The study was conducted in smallholder Arabica coffee farms in the Ijen Bondowoso region, Indonesia. The research utilized a Randomized Complete Block Design with the following treatments: P1= 30 ml of liquid biofertilizer BRE4 per ton of manure, P2= 60 ml of liquid biofertilizer BRE4 per ton of manure, P3= 90 ml of liquid biofertilizer BRE4 per ton of manure, P4= 120 ml of liquid biofertilizer BRE4 per ton of manure, K- = Without liquid biofertilizer and manure, K+1= 60 ml of liquid biofertilizer, and K+2= 5L of manure without liquid biofertilizer. The results showed that the P4 treatment reduced the population of parasitic nematodes and increased the diversity of free-living nematodes better than other treatments. A total of 18 genera of soil nematodes were identified, with the bacterial-feeding nematode genus (bacteriovore) being the most abundant compared to other trophic groups. The application of BRE4 and manure improved the soil ecosystem based on the nematode diversity level.</span></p> <p class="ABSTRACT"> </p>2024-09-21T00:00:00+00:00Copyright (c) 2024 Jurnal Penelitian Pertanian Terapanhttps://jurnal.polinela.ac.id/jppt/article/view/3316Effectiveness of Cacabean (Ludwigia hyssopifolia G.

Sembodohidayat.pujisiswanto@fp.unila.ac.id<p>The presence of bobontengan weed (Leptochloa chinensis) in rice fields is considered to be detrimental and need to be controlled. Compounds secondary metabolites plant can be used as herbicides for weed control. Cacabean (Ludwigia hyssopifolia) is one of the plants that contain secondary metabolites compounds. This study aimed to determine the potency of the extract of each part of cacabean plant and the level of concentration in germination and growth of bobontengan. The research was carried out from February to March 2023, in the Integrated Field Greenhouse, Faculty of Agriculture, University of Lampung. The research design used a Randomized Block Experiment Design (RAK). The treatment consisted of two factors with four groups. The first factor was the source of cacabean extract: leaves, stems and roots, while the second factor was the concentration of cacabean extract which consisted of 4 levels: 0, 5, 10 and 15%. The homogeneity of variance was tested by Bartlett's test and the additiveness of the data was tested by Tukey's test. If the assumptions are met, the data is analyzed by analysis of variance and differences in treatment mean values followed by the Least Significant Difference (LSD) test at the 5% level. The results showed that extracts of leaves, stems and roots of cacabean at concentrations of 5, 10 and 15% effectively suppressed seed germination and bobontengan weed growth. L.hyssopifolia leaf extract was most effective in suppressing germination, shoot height growth, and dry weight of bobontengan weed. Cacabean leaves and stem extracts were most effective in suppressing the percentage of germination, shoot height growth, and the total dry weight of bobontengan. Concentration of 15% of Cacabean extract was most effective in suppressing the growth of shoot height of 2 MSA, root length, and dry weight of bobontengan, while the concentration of 10-15% was most effective in suppressing the percentage of germination and shoot height of 4 MSA. Sources of cacabean leaves, stem and root extracts were influenced by the level of extract concentration in suppressing seed germination and crown height.</p>2024-09-21T00:00:00+00:00Copyright (c) 2024 Jurnal Penelitian Pertanian Terapanhttps://jurnal.polinela.ac.id/jppt/article/view/3379Chemical characteristics of biscuits made by porang (Amorphophallus muelleri) and corn (Zea mays) flour as emergency food product: formulation and dough pretreatment2024-09-17T08:03:11+00:00Gusti Ananda Syahputrigustisyahputri@staff.uns.ac.idRahma Bayunita Hapsarigustisyahputri@staff.uns.ac.idKania Uswamagustisyahputri@staff.uns.ac.id<p><em>Emergency Food Product (EFP) is a special food used in emergencies such as disasters by paying attention to criteria such as safe, palatable, easy to distribute, easy to consume, and nutritionally complete. Biscuits are processed products that can be developed to meet EFP criteria. Biscuits have a crunchy and dry texture so that they can last a long time and are favored by the majority of people. The main ingredient in making biscuits is wheat flour. However, it can be modified by utilizing local commodities such as porang and corn. Therefore, research needs to be done to get the right formulation for making biscuits made from local flour so that they can meet EFP criteria. This study used the factorial Complete Randomized Design (RAL) method, which consists of two factors, local flour formulation and dough pretreatment temperature. Analysis of the chemical characteristics including moisture, ash, protein, fat, carbohydrate, crude fiber content, and calories. The results showed that the formulation provided significant differences in moisture, ash, fat, protein, crude fiber, and carbohydrate content of local flour biscuit prototypes. The temperature difference of pretreatment (-18°C or 4°C) for 30 minutes before molding provides significant differences in moisture, fat, crude fiber, and carbohydrate content of local flour biscuit prototypes. Based on the number of calories per 50 gr of products, all prototypes of local flour biscuits with pretreatment at -18°C showed calories with an average of 234 kcal, meeting the calorie density requirements of emergency food products, which is a minimum of 233 kcal / 50 gr and a maximum of 250 kcal / 50 gr</em></p>2024-09-21T00:00:00+00:00Copyright (c) 2024 Jurnal Penelitian Pertanian Terapanhttps://jurnal.polinela.ac.id/jppt/article/view/3353Effect of Plasma Light on Increasing the Germination Rate of Shallot (Allium ascalonicum L.) Seed Origin TSS Sanren F1 Variety2024-06-11T01:35:21+00:00Mukhammad Akmal Sururakmalsurur01@gmail.comErma Prihastantieprihast@yahoo.co.idSri Widodo Agung Suedyeprihast@yahoo.co.idEndah Dwi Hastutieprihast@yahoo.co.idSri Darmantieprihast@yahoo.co.id<p><strong>ABSTRACT</strong></p> <p><em> </em>Sanren F1 shallot is a type of TSS variety that is widely cultivated by Indonesian onion farmers. The cultivation of Sanren F1 shallots is faced with the constraints of non-uniform germination and low seed viability, thus affecting seed quality and yield of TSS shallots. Plasma light radiation is one of the fast, economical and pollution-free plant breeding methods to improve seed performance and yield. This study aims to determine the effect of plasma light period on the germination rate of shallots from TSS seeds of Sanren F1 variety. The research design used was a single-factor Completely Randomized Design (RAL). The factor used is the irradiation period with 6 levels, namely: P0 (control), P1 (5 minutes radiation), P2 (10 minutes radiation), P3 (15 minutes radiation), P4 (20 minutes radiation), and P5 (25 minutes radiation). The variables observed were germination power, germination rate, seed vigor and sprout height. The data obtained were analyzed using Analiysis of Variance (ANOVA) at 95% confidence level for the formation of the results significantly influenced or not. If influential then continued with Duncan's Multiple Range Test (DMRT). The results showed that plasma light treatment at the irradiation level of 15 minutes (P3) gave a real effect on the growth parameters, namely germination height and was able to increase the germination and seed vigor to 100%.</p> <p>Keywords: Shallot, Germination, Plasma radiation, TSS</p>2024-10-25T00:00:00+00:00Copyright (c) 2024 Jurnal Penelitian Pertanian Terapan
