The use of liquid organic fertilizer with added AB Mix nutrients is an alternative solution to reduce the use of AB Mix nutrients. The aims of the research were to study interaction between the application of liquid organic fertilizer and the hydroponic system on the growth and yield of pak choy and the effect of concentration of liquid organic fertilizer and hydroponic systems on the growth and yield of pak choy. This experiment used Split Plot Design, which consist 2 factors, main plot was concentration of liquid organic fertilizer. Sub plot was hydroponic systems. Data obtained were analyzed with F test, and were continued with LSD at 5 percent when significant. Results showed that there was no interaction between the concentration of liquid organic fertilizer and hydroponic system for all observed parameters. The concentration of 25% liquid organic fertilizer + 75% AB Mix and concentration of 45% liquid organic fertilizer + 55% AB Mix gave better results on the parameters of height, number of leaves and fresh weight of pak choy plants grown in a hydroponic system when compared with a concentration of 65% liquid organic fertilizer + 35 % AB Mix. The NFT hydroponic system is better in the parameters of height and number of leaves of pak choy plants when compared to the DFT hydroponic system.

Potassium is really needed by melon plants to increase the sweet taste of the fruit. The element potassium can improve the size and quality of fruit during the plant's generative period and can add a sweet taste to the fruit. Meanwhile, phosphorus functions in the process of forming plant flowers and fruit as well as increasing fruit production and ripening. The aims of the research were to study interaction between the concentration and time application of MKP fertilizer on the production and quality of melon (Cucumis melo L.) and the effect of concentration and time application of MKP fertilization on the production and quality of melon (Cucumis melo L.). This experiment used Randomized Complete Block Design, which consist 2 factors, first factor was concentration of MKP fertilizer. Second factor was time application of MKP fertilizer. Data obtained were analyzed with F test, and were continued with HSD at 5 percent when significant. Results showed that there is an interaction between the concentration of MKP fertilizer and the time of application of MKP fertilizer for melon production and quality on the parameters of fruit weight, fruit diameter and total soluble solids. Providing MKP fertilizer with a concentration of 9 g.l^-1 and application time of MKP fertilizer 42 and 49 days after planting is a good combination for melon production and quality in the parameters of fruit weight (3.16 kg), fruit diameter (13.65 cm), and total dissolved solids (13.73 °brix). Providing MKP fertilizer with a concentration of 9 g.l^-1 is the best fertilizer concentration for melon production and quality in the parameters of fruit weight (3.16 kg), fruit diameter (13.65 cm), and total soluble solids (13.73 °brix). MKP fertilizer application time of 42 and 49 HST is the best time for melon production and quality in the parameters of fruit weight (3.16 kg), fruit diameter (13.65 cm), and total soluble solids (13.73 °brix).

This study aims to evaluate the growth and vitamin C content of red amaranth microgreens (Amaranthus tricolor) under various nutrient concentrations and growing media. The experimental design used in this study was a Randomized Complete Block Design arranged factorially 5 x 3 (15 treatments) with 3 repetitions. The first factor was the concentration of hydroponic nutrients at levels of 0 ppm, 100 ppm, 200 ppm, 300 ppm, and 400 ppm. The second factor was the combination of growing media, namely sand + sawdust, sand + rice husk charcoal, and sand + cocopeat, with a 1:1 ratio for each combination. Data obtained from the observed variables were analyzed using variance analysis and further tested with an LSD test at a 5% significance level. The observed parameters included germination rate (%), plant height (cm), number of leaves, leaf color, root length (cm), number of roots, plant weight (mg), and vitamin C content. The results showed that the use of sand + rice husk charcoal as a growing medium was very suitable for the germination of red spinach microgreens. However, for leaf color and root length, the use of sand + cocopeat was better. The sand + cocopeat medium combined with nutrient concentrations of 300 ppm and 400 ppm produced the best plant height and sample weight compared to other treatments. Furthermore, the sand + sawdust medium was very effective in producing the number of roots and the vitamin C content of red spinach microgreens.

The use of shade percentage is the main factor as a barrier to sunlight which functions to reduce the intensity of the sun and as a weed control. Liquid biological organic fertilizer is fertilizer that contains microbes and is useful for helping plant growth. The aim of this research is to determine the best shade presentation and concentration of liquid biological organic fertilizer and their combination on the growth and yield of celery plants. This research was carried out from August to November 2023 at the Lampung State Polytechnic Land. This research was a split plot experiment (3 x 3) which was repeated 3 times. The first factor used as the main plot is the percentage of shade which consists of three levels: no shade, 30% shade, 60%. The second factor used as a subplot is the concentration of liquid biological organic fertilizer which consists of three levels: control, 10 ml.l^-1, 20ml.l^-1. If the results show a significant effect, it will be continued with the Honestly Significant Difference (BNJ) test at the 5% level. Based on the observations result, it can be concluded that there is no good combination between the shade percentage treatment and the concentration of liquid biological organic fertilizer on the growth and yield of celery plants. The shade percentage treatment of 30% gave the best results for all observation parameters tested. Treatment of liquid biological organic fertilizer with a concentration of 10 ml.l-1 gave the best results in all observed parameters except for plant height parameters.

Pengaruh Media Tanam Campuran Serbuk Bambu dan Serbuk Kayu Terhadap Pertumbuhan dan Hasil Jamur Tiram (Pleurotus ostreatus)

Oyster mushroom is a commodity that is in high demand in the community. Oyster mushroom production in Indonesia is decreasing year after year as wood sawdust, which is often used as a media for oyster mushrooms, becomes increasingly difficult to get. Bamboo has a nutrient content similar to wood sawdust; therefore, bamboo sawdust can be utilized as a media for growing oyster mushrooms. The aim of this research was to find the best mixture of bamboo and wood sawdust for the growth and yield of oyster mushrooms (Pleurotus ostreatus). This research was carried out from July to October 2023 at Lampung State Polytechnic. This study used a randomized block design with one factor that was repeated four times. The following treatments were used: C0 = 100% wood sawdust, C1 = 90% bamboo sawdust + 10% wood sawdust, L2 = 80% bamboo sawdust + 20% wood sawdust, C3 = 70% bamboo sawdust + 30% wood sawdust, C4 = 60% bamboo sawdust + 40% wood sawdust, and C5 = 50% bamboo sawdust + 50% wood sawdust. The collected data was analyzed using analysis of variance (ANOVA) and then evaluated with LSD test at the 5% level. The results of this research were that the treatment of C5 = 50% bamboo sawdust + 50% wood sawdust gave the best results on the parameter of the mycelium growth rate, the time of the fruit body initiation (FBI), the number of hoods, the diameter of the hood, the thickness of the hood, the harvest, the harvest weight per baglog, and the total harvesting per plot.
