Abstract

Hydroponic techniques are one of the intensification efforts that will ultimately increase the use of land and nutrient solutions. Nutrient solutions use liquid organic fertilizers (POC), which contain the composition of nutrients needed by plants such as AB Mix fertilizer, but are sold at very cheap prices because they are made from fermented organic materials. The organic waste needed in making fertilizer, researchers use red onion skins, banana stems, and kiambang as liquid organic fertilizer because this waste is often found but has not been utilized optimally. The method in this research used a Completely Randomized Design (CRD) which was analyzed using Analysis of Variance, there were 5 treatments P0 (AB Mix 100% Control), P1 (POC 25% + AB Mix 75%), P2 (POC 50% + AB Mix 50%), P3 (POC 75% + AB Mix 25%), P4 (POC 100%). The purpose of this study was to determine the effect of a combination of liquid organic fertilizers of red onion skin, banana stem kepok and kiambang as liquid organic fertilizers for hydroponic lettuce. After conducting experiments and calculations using ANOVA, the results of the effect of the combination obtained the best combination of nutrients in treatment 1, namely 75% AB Mix and 25% POC, with the parameters of leaf width, plant height and the maximum number of leaves

Abstract

The processing of coconuts into Virgin Coconut Oil (VCO) is an alternative coconut processing method with strong potential for development in North Kalimantan, considering the region’s favorable environmental conditions for coconut cultivation. Over the past three years, coconut production in North Kalimantan has continued to decline, even though the number of productive coconut plantations remains relatively high. This decline in production is primarily attributed to the low bargaining price of fresh coconuts in the region. Therefore, alternative coconut processing strategies are needed to restore the economic value and purchasing power of coconuts. One promising coconut processing product is VCO. VCO can be produced using a fermentation technique that utilizes microorganisms present in yeast. In the fermentation-based VCO processing method, coconut milk is first allowed to settle until it forms a cream layer. The cream is then inoculated with yeast containing microorganisms such as Saccharomyces cerevisiae and Rhizopus oligosporus. These microorganisms produce protease and lipase enzymes, which hydrolyze the oil in the coconut cream with a high moisture content. Differences in processing techniques can influence the oil yield obtained. The use of yeast in VCO fermentation, combined with longer fermentation times, is expected to increase the yield. In this study, VCO was produced using yeast as a fermentation starter, and the resulting VCO was subsequently analyzed for quality. The experiment employed a Randomized Block Design (RBD). Two factors were observed: the type of yeast, consisting of V (without yeast), VR (bread yeast), and VT (tape yeast), and fermentation time, consisting of T1 (36 hours), T2 (48 hours), and T3 (60 hours). Each treatment was replicated three times, resulting in 9 treatments × 3 replications = 27 experimental units. The produced VCO was then analyzed for yield, as well as its physical and chemical properties. The results showed that treatment VRT3 (bread yeast with a fermentation time of 60 hours) produced the highest yield, reaching 25%. Furthermore, longer fermentation times resulted in higher VCO yields

Abstract

Wood ear mushroom is one of the edible mushrooms that are in great demand by the community and widely consumed in Indonesia. Wood ear mushroom cultivation has been inefficient; however, it has economic and nutritional value. Wood ear mushrooms naturally grow on woody media containing cellulose and hemicellulose. The aim of this study was to determine the potential of bamboo waste as a growing medium for the growth and yield of wood ear mushrooms. This research was conducted using Randomized Block Design (RBD) with one factor and five replicates. The treatments used are different baglog media compositions: B1: 100% sawdust waste; B2: 100% bamboo waste; B3: 75% bamboo waste + 25% sawdust waste; B4: 50% bamboo waste + 50% sawdust waste; B5: 25% bamboo waste + 75% sawdust waste. Each experimental unit consisted of 10 baglogs. Data were analyzed using analysis of variance and 5% of the Tukey HSD test. This study provides the following result: mycelium filled the baglog at 70 days after inoculation (DAI), B1 and B5 had the fastest time of mycelium growth and filled the baglog at 42 DAI. The fastest primordia appearance times were at B1 and B5 at 51 DAI and 52 DAI. The optimal treatment overall is the B5 treatment, indicating that bamboo waste can only replace 25% of the whole mixed media with sawdust

Abstract

Anthracnose (Colletotrichum spp.) is a major postharvest disease that reduces the quality of Cavendish banana (Musa acuminatata L.) fruit. This study aims to evaluate the effect of chitosan application as an edible coating material on anthracnose disease of banana fruit, with a focus on symptom diameter and weight loss. The research was conducted in vitro at the Laboratory of Plant Disturbing Organisms, Faculty of Agriculture, Singaperbangsa University of Karawang, in November-December 2024, using a completely randomized design with five concentrations of 0%, 0.5%, 1%, 2%, and 3% chitosan, with five replications. The results showed that the application of 2% chitosan effectively suppressed the development of anthracnose disease symptoms, with an average symptom diameter of 2.77 cm and produced a percentage reduction in weight loss of 10.42%. Meanwhile, 3% chitosan concentration produced the best percentage of weight loss suppression, which was only 7.07%. In contrast, the control treatment showed the highest severity with a symptom diameter of 5.13 cm and a percentage of weight loss of 14.61%. These findings indicate that chitosan, especially at 2% concentration, is effective as an anthracnose control agent on Cavendish banana during storage

Abstract

Pakcoy (Brassica rapa L.) is a horticultural commodity with high economic value, yet its productivity still fluctuates. This has encouraged the use of marginal soils such as Ultisols, which have less optimal physical and chemical properties. Biochar derived from livestock waste, such as that from chickens and goats, has the potential to be applied as a ultisoll soil amendment. This study aimed to determine the appropriate dosage of livestock manure Biochar that provides the best growth response of pakcoy (Brassica rapa L.) Nauli F1 variety on Ultisol soil. The research was conducted from March to July 2025 at an experimental field located on Krajan Hamlet Street, Sirnabaya Village, East Telukjambe, Karawang, West Java 41361. The method used in this research is the Experimental Method of Randomized Block Design (RAK) with a single factor with 7 treatments and 4 replications.. The treatments included: Control/No Biochar (P0), Chicken Manure Biochar 20 tons/ha (P1), Chicken Manure Biochar 15 tons/ha (P2), Chicken Manure Biochar 10 tons/ha (P3), Goat Manure Biochar 20 tons/ha (P4), Goat Manure Biochar 15 tons/ha (P5), Goat Manure Biochar 10 tons/ha (P6). The research results were analyzed using the F-test and further tested with the Duncan Multiple Range Test (DMRT) at the 5% significance level. The analysis showed that the application of livestock manure Biochar had a significant effect on the growth of pakcoy (Brassica rapa L.) variety Nauli F1 grown on Ultisol soil. The P1 treatment (Chicken Manure Biochar at 20 tons/ha) resulted in the highest values for plant height (25,12 cm), number of leaves (19,4 strands), and stem diameter (9,17 mm). Based on the research results, the application of chicken manure Biochar at a dose of 20 tons/ha was effective as a soil amendment for Ultisol and has the potential to enhance pakcoy growth sustainably

Abstract

Limited land and increasing awareness of healthy lifestyles encourage the application of efficient cultivation methods such as microgreens, which are young shoots of vegetables that are rich in nutrients and are harvested in 7–21 days. This study aims to examine the influence of the type of LED lamp on the growth of several microgreens of the Brassicaceae family. The research was carried out using a split plot Group Random Design (RAK). The main tile factor is LED light (6 levels: inner control, outdoor control, blue LED, red LED, red-blue LED, and white LED), while the subplot consists of three types of microgreens (cabbage, turnips, and broccoli), with two replicas (36 experimental units). The data was analyzed using a 5% variety analysis, followed by the Duncan Multiple Range Test (DMRT) if there were any real differences. The results showed that there was no interaction between LED lights and plant types on plant height at 4, 7, and 10 days after planting (dap), rate of increase in number of leaves, and relative growth rate. Separately, red LEDs produce the highest plants, blue LEDs increase the number of leaves, and sunlight provides the highest LPR. Horseradish plants show the best growth compared to broccoli and flower cabbage.

Abstract

Shallot (Allium cepa L.) is one of the most important horticultural commodities, playing a significant role in human life and being widely cultivated in Indonesia. One approach to improving the growth and yield of shallot plants is the application of liquid organic fertilizer during cultivation. This study aimed to determine the effect of HENS Liquid Organic Fertilizer (HENS LOF) concentrations on the growth and yield of shallots and to identify the most effective concentration for enhancing their growth and productivity. The research was conducted at the Lebak Bulus Tissue Culture Laboratory from July to December 2024. The experiment employed a Randomized Complete Block Design (RCBD) with a single factor, namely the concentration of HENS Liquid Organic Fertilizer, consisting of five treatments: P0 = 0 mL/L, P1 = 10 mL/L, P2 = 20 mL/L, P3 = 30 mL/L, and P4 = 40 mL/L. Each treatment was replicated five times, resulting in a total of 25 experimental units. The observed variables included plant height, number of leaves, number of bulbs, bulb diameter, fresh plant weight, and dry plant weight. The results showed that HENS Liquid Organic Fertilizer concentration significantly affected plant height, number of leaves, number of bulbs, bulb diameter, fresh plant weight, and dry plant weight. The application of HENS Liquid Organic Fertilizer at a concentration of 40 mL/L produced the best growth and yield, with a plant height of 41.9 cm, 22.5 leaves per plant, 7.8 bulbs per clump, a bulb diameter of 21.6 mm, a fresh plant weight of 37.9 g, and a dry plant weight of 28.9 g
