Abstract

Organic waste bioconversion through maggot cultivation is believed to be a solution for managing organic waste based on a circular economy. Maggot cultivation has been widely carried out by Bank Sampah managed by the community in Indonesia, one of which is located in Bengle Village, Karawang District. Bank Sampah (BS) of Bengle Village has been able to reduce organic waste and produce Kasgot, reaching 75.00% and 25.00%, respectively. This study aims to examine nutritional content of maggot and characteristics of kasgot produced by BS of Bengle Village. The results showed that fresh and dried maggot contained quite high fat and protein, of 38.99%; 29.65% and 40.94%; 34.75%, respectively. These values make both maggots feasible as sources of animal fat and protein for poultry. Furthermore, Kasgot contains N-total, P2O5, K2O, Fe, and Pb each of 3.98%; 2.80%; 3.32%; 332.18 ppm; and 0.26 ppm has met the minimum specifications for solid organic fertilizer and compost from organic waste. However, the C/N ratio (6.40) and moisture content (22.77%) did not meet these standards and indicated that Kasgot was not stable as an organic fertilizer. Despite that, the quality of Kasgot can be improved through advanced fermentation processes such as vermicomposting so that it can be used as a substitute for inorganic fertilizers for plant growth and improve soil conditions.

Abstract

Pest attacks are an important problem in vegetable cultivation practices. Pest control using synthetic pesticides is still widely used, but excessive use has a negative impact on human health and the environment, one of which is insect diversity. As an alternative to pest control, pesticides can be used with active ingredients that are secondary metabolites from plants or commonly called plant pesticides. The purpose of this study is to evaluate the influence of vegetable pesticides on insect diversity and the intensity of leaf caterpillar pest attacks on kailan plants. The method used is an experimental method using a single-factor Random Group Design (RAK) consisting of 5 treatments and 5 replicates. These treatments include K (Control), PP (Papaya Leaf Pesticide), PM (Neem Leaf Pesticide), PB (Babanandan Leaf Pesticide), and PS (Synthetic Pesticide). Insect sampling was done 4 times at 7-28 hst with an interval of 7 days using slope pifall traps, yellow board traps and insect nets. The data was analyzed using ANOVA variety analysis and a follow-up test of BNT at 5%.  The results of the variance analysis showed that the PP treatment was able to maintain diversity with an index value of H'= 2.689 and an abundance of 369.800. PP treatment gave the lowest caterpillar attack intensity value ranging from 0.833% – 15,000%, which is a plant-based pesticide treatment with results close to synthetic pesticide treatment. Therefore, papaya leaf plant pesticides can be recommended as an alternative pesticide to maintain diversity and suppress the intensity of pest attacks in kailan cultivation.

Abstract

Cauliflower production in Indonesia decreased by 38.79% from 2021 to 2022, partly due to Shrinking agricultural land. Non-conventional cultivation methods, such as wick hydroponics and aeroponics, offer alternative solutions to traditional farming. In addition, one key factor affecting cauliflower yield is abiotic stress, particularly high pH levels in nutrient solutions. This study aims to examine the effect of combining non-conventional growing systems with alkaline pH stress on the growth and yield of cauliflower (Brassica oleracea L. var. botrytis) cultivar Larissa F1 This research used an experimental approach with a single factor Completely Randomized Design (CRD) with six treatments, each replicated four times, resulting in 24 experimental units and a total of 72 plants. The treatments included wick hydroponics and aeroponics under three pH ranges: 6–7, 7–8, and 8–9. Data were analyzed using ANOVA and further tested with Duncan's Multiple Range Test (DMRT) at a 5% significance level. Results showed that wick hydroponics with pH 8–9 produced the highest average leaf count at 14 days after planting (7.5 leaves). Aeroponics with pH 6–7 yielded the highest average leaf count at 42 days after planting (13.8 leaves), and also achieved the greatest average curd height and root length (10 cm and 62.5 cm, respectively), although these were not significantly different from other treatments.

Abstract

There was a decline in melon production in 2021–2022 due to suboptimal cultivation practices in land management and limited land availability resulting from the conversion of agricultural land. This issue can be addressed through the use of a hydroponic system and appropriate growing media. This study aimed to determine the best enrichment of growing media with the addition of tea waste to support the growth and yield of melon plants. The research method used was a Completely. The research was conducted using a single-factor Randomized Complete Block Design (RCBD) consisting of 10 treatments, each replicated three times. The treatments included: A (Cocopeat + Zeolite 1:1), B (Cocopeat + Zeolite 1:1 + 100 g Tea Waste), C (Cocopeat + Zeolite 1:1 + 200 g Tea Waste), D (Cocopeat + Zeolite 1:1 + 300 g Tea Waste), E (Cocopeat + Zeolite 1:1 + 400 g Tea Waste), F (Cocopeat + Fern Roots 1:1), G (Cocopeat + Fern Roots 1:1 + 100 g Tea Waste), H (Cocopeat + Fern Roots 1:1 + 200 g Tea Waste), I (Cocopeat + Fern Roots 1:1 + 300 g Tea Waste), and J (Cocopeat + Fern Roots 1:1 + 400 g Tea Waste). The results showed that the enrichment of growing media with tea waste had a significant effect on plant height, leaf number, stem diameter, fruit weight per plant, fruit circumference, flesh thickness, and sweetness level of the melon fruit. The best results were observed in treatment J, which produced the highest values across all parameters, including a plant height of 144.90 cm and a fruit sweetness level of 15.66 °Brix.

Abstract

The main issues faced in current cultivation practices are the reduction of available land and the decline in production. One solution is to shift from conventional farming to non-conventional or urban farming systems, such as hydroponic wick systems and aeroponics. The success of hydroponic and aeroponic cultivation is strongly influenced by the plant’s ability to absorb nutrients, particularly the acidity level (pH) of the nutrient solution. This study aims to determine the best combination of non-conventional cultivation systems and acidic pH stress of nutrient solutions on the growth and yield of cauliflower (Brassica oleracea L. var. Botrytis) cultivar Larissa F1. The experiment used a single-factor Randomized Block Design (RBD) consisting of six treatments and four replications: hydroponic wick system + pH 4–5, pH 5–6, pH 6–7, and aeroponics + pH 4–5, pH 5–6, and pH 6–7. Data were analyzed using F-test and Duncan Multiple Range Test (DMRT) at a 5% significance level. The results showed that the combination of cultivation systems and acidic pH significantly affected plant height at 56 DAT, number of leaves at 42 DAT, leaf area, root length, fresh weight, curd diameter, curd height, curd weight, and trimmed curd weight. The best treatment was the wick system with pH 6–7, producing a curd height of 13.6 cm, plant fresh weight of 585.5 g, curd weight of 291.8 g, and trimmed curd weight of 277.6 g.

Abstract

Jamur merang (Volvariella volvaceae) merupakan komoditas hasil pertanian yang bergizi serta bernilai ekonomis tinggi. Kandungan nutrisi pada media tumbuh merupakan faktor yang mempengaruhi produksi dan hasil jamur merang. Oleh karena itu, penggunaan media tumbuh yang tepat bisa menjadi alternatif solusi peningkatan produksi jamur merang. Tujuan penelitian ini adalah untuk mendapatkan kombinasi media tumbuh dan nutrisi organik yang memberikan hasil tertinggi jamur merang. Percobaan dilaksanakan di kumbung jamur merang Desa Tamelang, Kecamatan Purwasari, Kabupaten Karawang pada bulan Juli sampai Agustus 2021. Metode penelitian yang digunakan adalah Rancangan Acak Kelompok (RAK) dengan 3 ulangan. Terdapat 10 kombinasi perlakuan, yaitu A (kontrol), B (bekatul + ekstrak kulit kentang), C (Bekatul + air kelapa), D (Bekatul + air leri), E (ampas tahu + ekstrak kulit kentang), F (ampas tahu + air kelapa), G (ampas tahu + air leri), H (cocopeat + ekstrak kulit kentang), I (cocopeat + air kelapa), dan J (cocopeat + air leri). Pengaruh perlakuan dianalisis dengan analisis ragam dan apabila uji F taraf 5% signifikan, maka untuk mengetahui perlakuan yang terbaik dilanjutkan dengan uji lanjut DMRT (Duncan Multiple Range Test) pada taraf 5%. Hasil penelitian menunjukkan bahwa terdapat pengaruh nyata kombinasi jenis media tumbuh dan nutrisi organik terhadap parameter bobot total per petak, tetapi tidak berbeda nyata pada parameter lainnya. Perlakuan I (cocopeat + air kelapa) memberikan hasil tertinggi pada bobot total per petak jamur merang yaitu 228,51 g.
