Iskandar Zulkarnain, Andy Eka Saputra, Kelik Istanto — Sel, 14 Mar 2023 00:00:00 +0000

In general, the manufacture of paving blocks uses a mixture of cement, coarse aggregate, fine aggregate and water which is mixed into one and then shaped. The results of previous studies showed that the coefficient of runoff that occurred on land with ordinary paving block covers was 0.41 - 0.46 or there was an increase in surface runoff by 171% - 215% compared to hard soil without paving block covers. This indicates that there is a potential for increased puddles when it rains. Based on this, it is necessary to increase the ability to pass water from paving blocks in the form of modifying the character of the existing paving blocks by making porous paving blocks coupled with the application of innovative materials without cement. This research was conducted with the aim of designing a porous paving block material without cement which is expected to be a solution in overcoming the inundation that occurs. The result of this research show that the test results get a permeability value of 77.36% or in other words a runoff coefficient of 0.22, an infiltration rate of 1.15 cm/s and an average compressive strength of 106.886 kg/cm2.

Identification of Rice Disease Types Based on Digital Images Leaves Using Algorithm Support Vector Machine (SVM)

Kurniawan Saputra, Zuriati Zuriati — Sel, 14 Mar 2023 00:00:00 +0000

Diseases that commonly attack rice plant are: bacterial leaf blight, brown spot, and leaf smut. The disease can lead to a significant decrease in the quality and quantity of agricultural products so that it can cause economic loss. Farmers usually find out that the rice plant has been affected by the disease when it already shows severe symptoms and has spread to various parts of the plant so it is too late to control. Another thing that causes the failure of disease management in rice plant is the lack of knowledge of farmers about the symptoms of the disease which causes the provision of inappropriate treatment actions caused by errors in identifying the type of disease that appears with almost the same physical symptoms. Therefore, we need a solution in the form of a model that is able to identify the types of disease in rice plant so that farmers including the general public can detect disease that attack rice plant accurately and quickly. This study aims to develop a model for identification of rice plant disease based on plant leaf images. The research stages are: collecting rice leaf image data, sharing data for training and testing data using cross validation techniques, implementing the SVM algorithm and evaluating the model using a confusion matrix and calculating the accuracy, precision and recall of the SVM algorithm. The results of the evaluation of this identification model indicate that SVM can identify leaf disease of rice plant with an accuracy value of 0.90 or 90%, a precision of 0.902 or 90% and a recall of 0.900 or 90%.

Zuriati Zuriati, Dulbari Dulbari, Dewi Kania Widyawati — Sel, 14 Mar 2023 00:00:00 +0000

Aquaponics is a cultivation method that combines plant cultivation and freshwater fish farming. Aquaponics can be applied to a limited land such as house yard, which is very suitable to be applied in urban areas with limited land. Aquaponics cultivation requires a controlled environment and more maintenance and care compared to other cultivation techniques such as hydroponics, since cultivators must maintain and take care for both plants and fish at the same time. To get the maximum yields, it is necessary to control the time, ambient temperature, humidity value, water level, pH, and water temperature. The existing aquaponics farming that are carried out by farmers or cultivators in general still uses a simple system through measuring the pH level of the water (using the pH meter equipment), water level, water temperature, and ambient temperature, so that farmers or cultivators need more time and manpower to maintain and take care of the plants and fish. Therefore, we need a solution in the form of a monitoring system that can monitor the environmental conditions of plants and fish continuously throughout the day. The monitoring system developed has the ability to monitor time, ambient temperature, humidity, water level, pH, and water temperature. The system was developed using the rapid application development (RAD) system development method. The RAD consists of four stages: requirements planning; system design; construction; and cutover. The test result using the black box testing method prove that the monitoring system can monitor time, ambient temperature, humidity, water level, pH, and water temperature.

Dadih is a traditional West Sumatra dish derived from buffalo milk that is naturally fermented in bamboo vats at room temperature for 24-48 hours. The aim of this study was to determine the antibacterial activity of buffalo salt against the acne-causing bacteria Propionibacterium acnes, and the antioxidant content in buffalo salt can inhibit the formation of melanin pigment in the skin. This study used 12 curd samples including 4 treatment groups and 3 replicates each, in which the first treatment (D0) was 100% buffalo curd, the second treatment (D1) with 75% milk concentration. Eastern buffaloes supplemented with aquatic products, the third treatment. Treatment (D2) with 50% concentration of buffalo curd supplemented with aquadest and treatment 4 (D3) with 25% concentration of curd supplemented with aquadest. Each group was tested for bacterial inhibition by diffusion method and tested for antioxidant content by DPPH method. The obtained data were analyzed by ANOVA and continued with the DMRT test. The results of statistical tests on antibacterial activity of buffalo dung mushrooms showed that there was no significant difference (P 0.05) between groups D0, D1 and D2, but significantly different from D3. While the statistical results on antioxidants in buffalo curd showed no significant difference (P 0.05) compared with the four treatment groups. The highest antibacterial activity was shown in the D1 group (12.11 ± 2.94 mm) and the highest antioxidant content was in the D2 group (32.76 ± 2.67 ppm). Based on this, it is concluded that buffalo curd can be used as an alternative to natural facial skin care.

Sel, 14 Mar 2023 00:00:00 +0000

Java cardamom (Amomum compactum) is hardly propagated with rhizome without the mother plant. In vitro culture could overcome the problem through mass propagation for seedling production or other purposes such as genetic material for mutation breeding. The aim of the research was to generate protocol of establishing Java cardamom micropropagation. This research consisted of 4 aspects i.e. shoot induction of mother plant (without Plant Growth Regulator (PGR) and using PGR BAP (6-benzylaminopurine) 1000 ppm), explant origin selection (main stem, rhizome bud height >3 cm, rhizome bud height ≤3 cm and lateral rhizome), sterilization procedure establishment (4 methods differ in the use of detergent, HgCl2, Alcohol, NaOCl, Ethanol, Iodine and soaking time in fungicide and bactericide) and shoot multiplication (MS 0, MS 0 + BAP 1 ppm and MS 0 + BAP 1 ppm + NAA 1 ppm). Result showed the application of 1000 ppm BAP to mature plant could induce shoot emergence. The best explant source was rhizome bud that smaller or equal to 3 cm. The highest survival rate (71%) was recorded when explants disinfected with 70% alcohol for 30 seconds and 0.1 % mercuric chloride for 5 minutes. Java cardamom in vitro culture showed highest shoot multiplication rate in MS 0 + BAP 1 ppm medium (multiplier of 10 shoots/explant in 18 weeks). Keywords: explant, in vitro propagation, Plant Growth Regulator, rhizome, shoot multiplication

Potato Leaf Disease Detection with Convolutional Neural Network Method

TS Jaya , D Sahlinal — Sel, 14 Mar 2023 00:00:00 +0000

Potatoes are recognized by people as a staple food abroad because they contain carbohydrates. In Indonesia, potatoes are still considered a luxury vegetable. However, potatoes are a portion of delicious and very nutritious food. One of the main diseases that attack potato plants is late blight and another disease that is often encountered in potato plants is dry blight (early blight). In this research, we develop software to detect potato leaf disease using the convolutional neural network method. The advantage of the convolutional neural network method is that it can automatically extract important features from each image without human assistance, besides that the convolutional neural network method is also more efficient than other neural network methods, especially for memory and complexity. This study resulted in an application with all functions running correctly based on the results of the BlackBox test.

The aim of this study was to determine the serum indices of rabbit doe fed biscuit diets containing Moringa oleifera lamm based on urban organic waste. A total of 25 rabbits doe were used divided into 5 groups based on body weight with 5 treatments in each group. T0 was the control diet while T2, T4, T6, and T8 received additional 2%, 4%, 6%, and 8% moringa leaf meal, respectively. The treatment was given during pregnancy until the kit was 21 days old. Blood samples collected from rabbits does on the last day of study and evaluated for serum biochemical indices, data obtained were analysed statistically. The variables observed were cholesterol, glucose, total protein, albumin, globulin, creatinine, and urea. The results showed that cholesterol, total protein and albumin in the blood serum of rabbit doe were significantly different (P<0.05) while glucose, globulin, creatinine, and urea were similar (P>0.05) between the groups. Giving Moringa leaf meal up to 8% in biscuit diet was able to reduce cholesterol content in the blood from 75.10 mg/dl to 58.20 mg/dl. Total protein in blood serum increased from 6.94 g/dl to 8.24 g/dl. This increase in total protein seems to be influenced by a significant increase in albumin from 4.08 g/dl to 5.58 g/dl. The other variables still have values in the normal level such as controls.

Capture fisheries in Ogan Komering Ilir Regency, especially in Pedamaran sub-district, are mostly sourced from the floodplain area. Therefore, fishermen use various types of fishing gear in their fishing activities. Information on various types of fishing gear used by fishermen in Pedamaran sub-district is still minimal. This research was conducted in May 2022. This reasearch aimed to inventory of the types of fishing gear were operated by fishermen in floodplain, Pedamaran District. The method used in this research is a survey method and interviews with fishermen who land fish at the Land Fisheries Fish Auction Place, Pedamaran sub-district. Based on the results of the study, the fishing gear used by fishermen is divided into four groups, namely the pot trap group (sengirai, bubu, kemilar, pukat, roket), barrier trap (kilung, waring), gill net (net) and hook line (pancing, tajur).

The Effect of Online Learning on Student’s Academic Achievement for Accounting Subject

Artie Arditha Rachman, Dian Nirmala Dewi, Endang Asliana — Sel, 14 Mar 2023 00:00:00 +0000

Teaching and learning activities (TLA) for accounting courses were originally held offline, guided and accompanied by lecturers. Online TLA which suddenly had to be held due to the Covid-19 pandemic did leave doubts and questions regarding the achievement of student competencies. If theoretical lectures are considered 100% optimal, then this is not the case for practical activities. This activity is considered not optimal in its implementation online, although maximum efforts in providing practical materials in the form of modules and guides via video, coupled with meetings via zoom or other online meeting media have been taken as a form of learning method that is similar as possible to offline learning. This study aims to see if there is any effect of online learning method (synchronous and asynchronous) on student’s competency in accounting. The experimental results show that there is a difference between the students' pretest and posttest scores. It means that both synchronous and asynchronous learning methods have an impact on students’ competencies. Furthermore, the experimental results prove that there are differences in competencies between students who receive asynchronous and synchronous learning. Better performance were obtained by synchronous one.

DP Widiyani, JSS Hartono, AM Santika — Sel, 14 Mar 2023 00:00:00 +0000

Pesawaran Regency is one of the largest cocoa-producing areas in Lampung Province. Pesawaran Regency has a cocoa area of 27,411 ha with total production in 2021 reaching 30 thousand tons, with an average production per hectare of approximately 1 ton of dry cocoa beans. This is considered to be quite low considering the potential for cocoa production, which is up to 2 tons per hectare of dry beans. There are many aspects that lead to low cocoa production in Pesawaran Regency [1]. In connection with the efforts to rejuvenate the cocoa plant in Pesawaran Regency with the use of land, vegetation and the area of the area, it is hoped that there will be an appropriate use of cocoa cropping patterns. Thus the analysis of land suitability and climate is of course very important for efforts to make efficient use of land for cocoa commodities. Suitable land and climatic conditions will produce good cropping patterns and optimal results. This study uses a survey method by taking several sample points of community gardens that will be replanted in the cocoa revitalization program. Sampling points were taken based on the condition of the land and the condition of land cover or vegetation in the pesawaran cocoa area. Each village is classified into 3 areas. Based on the results and discussions that have been obtained, it can be concluded that the experimental plots of the Sungailangka and Wiyono Village cocoa farms each produced a micro-climate that varied with each element meeting the appropriate cocoa growing requirements.

DP Widiyani, JSS Hartono, Lela Mispandi — Sel, 14 Mar 2023 00:00:00 +0000

Pesawaran Regency is one of the largest cocoa-producing regions in Indonesia, ranking 5th, therefore cocoa plants are very strategic in this region. According to [1] Pesawaran Regency has a cocoa area of 27,411 ha with a total production in 2021 reaching 30 thousand tons, with an average production per hectare of approximately 1 ton of dry cocoa beans. This is considered still relatively low when compared to its potential. One of the cocoa-producing areas, namely the Gedong Tataan sub-district, is one of the largest areas for cocoa plants but its production is still relatively low at less than 1 ton/ha. Some of the problems in the Gedong Tataan sub-district include old plants, pests and unknown clones. The first step in a good cocoa cultivation business is to prepare clear planting material [2]. A clear cocoa clone will determine the sustainability of the cocoa business in the long term and benefit both production and increasing community income. The research was conducted using a survey method. Samples of respondents and cocoa plantations were determined purposively from cocoa plantation areas in Gedong Tataan sub-district, Pesawaran district, namely Sungai Rare and Wiyono villages. Observation variables in this study include identification of clone types (description) and climatic conditions. The obtained clone observation data were analyzed descriptively according to the morphological characteristics of each clone. Based on the data obtained, 5 types of superior clones were obtained including MCC 01, MCC o1, Sulawesi 01, Sulawesi 02 and BB. Based on the 5 clones, all of them had their own advantages and disadvantages, but in the Gedong Tataan sub-district the most commonly found was the MCC 02 clone with high production potential.

Broiler are live microorganisms that are given in adequate amounts to provide health benefits to the body. Probiotics are live microorganisms that have a good effect on the health of the host (broiler). The use of probiotics for broilers has a function to increase growth and feed efficiency. Giving probiotics in drinking water has the potential to help the digestive system in broilers. The general objective of this research is to examine the use of probiotics as an alternative to AGP (Antibiotic Growth Promoter) in broiler feed and drink. The experimental design used was Completely Randomized Design with 4 treatments and 5 repetitions, namely T0 = Control (Without Probiotics), T1 = Basal Diet + Probiotic Powder (50 mg/Kg), T2 = Drinking Water + Probiotic Liquid (1 ml/L) , and T3= Combination (Basal Diet + Probiotic Powder 25 mg/kg) with (Drinking Water + Probiotic Liquid 0.5 ml/L). Data were analyzed using analysis of variance and further test using LSD (Least Significant Different). Observations made Average Day Gain (ADG), Body Weight (BW) and mortality in broilers related to the use of probiotics. In the observation of body weight at the age of 7, 14, and 21 days, the addition of probiotics was significant. Observation of body weight at the age of 14 days in treatment T2 and T3 was significantly different. In the observation of Average Day Gain (ADG) at the age of 7,14, 21 and 28 days are significant. After further testing, Least Significant Different (LSD) in the grower phase (14 days) was significantly different in T2 and T3 treatments. In monitoring overall mortality for 28 days, the addition of prebiotics significantly reduced mortality compared to controls. The conclusion is that the addition of probiotics is significant in observing the performance of body weight, adg, and mortality. Giving probiotics had a significant effect (T2 and T3) on the addition of ADG grower.

V.R. Pertiwi, N. Riffiandi, A. Sofiana — Sel, 14 Mar 2023 00:00:00 +0000

In developing countries such as Indonesia, the health of small ruminants such asgoats is not given much attention because the medical costs are very high, it causing a farmer to prefer to sell their livestock, even though at relatively low prices if there are signs of infection, one of which is due to parasitic diseases. This research was carried out in the village of Rajabasa Lama. The study was conducted using a descriptive method by collecting feces from the goat pens in that area. Furthermore, the examination was carried out using a native test and fecal floating examination using a fluid sugar medium. The results of the examination of gastrointestinal tract parasites that were found included parasites from the protozoan Entamoeba sp. and Eimeria sp. and also parasites from the Trematoda family, the eggs of the worm Fasciola sp.. Eimeria sp. is a parasite that quite often infects ruminants, including goats.

Rizky Nadia, Sumiati Sumiati, Tuti Suryati — Rab, 01 Peb 2023 00:00:00 +0000

. Eggs are one of the animal foods that can be easily damaged but have a long shelf life. The objective of the research was to analyze physical quality of IPB-D2 candidate chicken strain eggs which had been supplemented with vitamin E in feed and storaged for 1 and 14 days at room temperature. This research used 30 IPB-D2 candidate chicken strain eggs, from chickens that fed treatment diets during 30 days. This study used a factorial completely randomized design with 3 vitamin E supplementation levels (0 ppm, 100 ppm, 300 ppm), 2 duration of storage treatments (1 and 14 days), and 5 replications. The data were analyzed using ANOVA and if there was a significant difference, it was further analyzed using Duncan Multiple Range Test. The results showed that supplementation 300 ppm vitamin E significantly increased yolk score (p<0.05). Storage treatments affects the percentage of albumen, the percentage of yolk, albumen index, yolk index, and haugh unit (p<0.05). However, there was no interaction between vitamin E supplementation levels and storage treatments. The conclusion of this study that supplementation of vitamin E generally did not affect physical quality of egg stored at the different time, except yolk score. Supplementation of 100 ppm vitamin E increased yolk score. The storage of egg for 14 days can reduce egg quality.

Quality seeds can be met if during their growth can take place well and produce healthy plants. One of the obstacles in maintenance activities is the recovery of seedling growth after a severe attack of leaf spot disease at the age of 5-6 months in the main nursery. The way that can be done is to test the effectiveness of nitrogen and magnesium fertilization on the recovery of seedling growth. This study aims to obtain the best concentration of nitrogen fertilizer and magnesium fertilizer in optimizing the growth of oil palm seedlings that have been attacked by diseases in the main nursery. The research will be carried out at the Lampung State Polytechnic's Oil Palm Nursery Unit. The experimental design used was a factorial randomized design (RAF) 2 x 3 with 5 replications. The first factor of treatment was KNO₃ fertilization and the second factor was kieserite fertilization. The first factor is KNO₃fertilization with a concentration of 1% and 2%. The second factor is kieserite fertilization which consists of doses of 0 g, 5 g, and 10 g. The observed variables were seedling height, seedling diameter, number of midribs, level of greenness of leaves and leaf area of tillers. Observational data will be analyzed by F test at level = 5%. If the results of the analysis of variance are significant, it will be continued with the further test of the smallest significant difference (BNT) at the level of = 5%. The results showed that the application of 2% KNO3 fertilizer with the addition of 10 g of kieserite was able to produce the best growth recovery on all observed variables.

Community Based Tourism Model Development in a Cultural Conservation, Agro Tourism Management, and Creative Economics in Sailing Tourism Village, Tanggamus Regency

Meyliana Astriyantika, Refdi Akmal — Sel, 14 Mar 2023 00:00:00 +0000

The principle of sustainable tourism development is derived from various
attractions management concepts, which is applied among others in ecotourism and tourism
villages. The tourism village is developed by exploring the potential that exists in the
village, both natural potential, customs of the surrounding community, cultural uniqueness,
and patterns of life that occur in daily life. The tourism village directly involves the
participation of the local community as a party that is in direct contact withtourists, so that it
becomes a special concern to determine the management model by making the community a
subject, not just an object. One of the tourism villages that has been active in Lampung
Province is in Tanggamus Regency, namely Sailing tourism village as a weaving industry
center of Lampung. The village offers the attractiveness ofthe process of making Lampung
tapis woven cloth to the sales process. In addition, thereare also agro-tourism locations with
fruit gardens as objects and waterfalls, as well as springs managed by the community. The
existence of the Sailing tourism village, which is positioned in the middle of community
settlements and even formed with collaboration between communities, becomes a special
demand that the management of this area should be designed with the participation of the
community as tourism actors, one of which is through the concept of developing community
based tourism (CBT) in 3 participations, namely ideas, material, and real action. The
community based tourism model designed from the findings in the Sailing tourism village
has 4 stages, namely identifying potential that can be developed into attractiveness, raising
awareness to the public as subjects and tourist objects, developing a management
organization with the formation of organizational structures and governance documents, and
implementing tourism programs and businesses.
