Induksi mutasi dengan sinar gamma merupakan metode pemuliaan tanaman yang efektif dalam upaya merakit varietas unggul baru. Cabai rawit Prentul Kediri adalah komoditi lokal yang berpotensial untuk dikembangkan menjadi varietas unggul baru. Tujuan dari penelitian ini yaitu untuk mengetahui pengaruh mutasi sinar gamma terhadap tingkat keragaman genetik dan heritabilitas pada generasi M1 cabai rawit Prentul Kediri. Penelitian dilakukan pada bulan Agustus 2021-Februari 2022, di Desa Ketindan, Kecamatan Lawang, Kota Malang, Jawa Timur. Penelitian ini dilakukan terhadap generasi M1 cabai rawit Prentul Kediri hasil keturunan dari generasi M0 hasil induksi mutasi sinar gamma dengan dosis 100 Gy, 200 Gy, 300 Gy. Rancangan percobaan menggunakan rancangan acak kelompok (RAK) dengan tiga ulangan. Analisis yang diigunakan yaitu analisis BNJ taraf 5%, standar deviasi (SD), koefisien keragaman genetik (KKG), koefisien keragaman fenotipe (KKF) dan heritabilitas (H2). Hasil penelitian menunjukkan terdapat pengaruh signifikan pada karakter jumlah daun, umur berbunga, jumlah buah per tanaman dan bobot buah per tanaman. Tingkat keragaman genetik dan heritabilitas pada populasi M1 hasil dari masing-masing dosis mutasi yaitu dari rendah sampai tinggi (beragam).

Melon plants are a high-value horticultural commodity favored by consumers for their taste and market appeal. This study aimed to determine the best combination of Mono Potassium Phosphate (MKP) fertilizer and Amino Acid Liquid Organic Fertilizer (LOF) doses to enhance the growth and yield of melon plants while promoting nutrient balance and minimizing environmental impact. The experiment was conducted from April to July 2024 in a greenhouse located in Jatirejo Village, Nganjuk Regency, with LOF composition analysis carried out at the BSIP Laboratory. A factorial experiment using a Randomized Block Design (RBD) was applied with two factors: MKP fertilizer dose (5, 10, and 15 g/plant) and LOF dose (0, 50, 100, and 150 ml/plant), resulting in 12 treatment combinations replicated three times. Observed parameters included plant length, number of leaves, fruit weight, fruit diameter, and fruit length. Data were analyzed using ANOVA and followed by a 5% BNJ test for significant differences. The results showed a highly significant interaction between MKP and LOF treatments, with the combination of 15 g MKP and 100 ml LOF per plant producing the best outcomes across most growth and yield parameters, indicating that this treatment is optimal for maximizing melon productivity in a sustainable manner.

Bodag Village in Kare District, Madiun Regency, has an agroecological environment that strongly supports cocoa cultivation, with approximately 40 hectares of farmland managed by the Murah Sandang Farmer Group and strengthened by downstream initiatives through the Bodag Chocolate House. However, this potential has not yet translated into optimal productivity, as farmers face several constraints, including limited availability of organic fertilisers, rising production costs due to higher chemical fertiliser prices, and insufficient understanding of sustainable cultivation practices and the utilisation of organic waste. To address these challenges, this community service program implemented a participatory training on the production and application of Liquid Organic Fertilizer (POC) using locally available materials as a more environmentally friendly and economical alternative. The training included socialization, hands-on POC production, technology application in demonstration plots, and evaluation of program effectiveness. The results showed a significant improvement in participants’ knowledge, indicated by an increase in the number of participants in the “understand” and “highly understand” categories and the disappearance of the “do not understand” category. Participants’ enthusiasm also increased in each training session, and the farmer group successfully produced high-quality liquid and solid organic fertilizers. The program's outcomes demonstrate that the training effectively enhanced farmers’ technical capacity, improved their understanding of sustainable cultivation through organic fertiliser production, and strengthened the sustainability of cocoa farming as Bodag Village’s leading commodity.

Melons are a horticultural commodity with high economic value and are popular among consumers. Efforts to improve melon cultivation to increase production and fruit quality are necessary. The flowering phase in melon cultivation is a critical phase that greatly affects the success of the melon harvest. The combination of MKP fertilizer, which is an inorganic fertilizer, and amino acid LOF (Liquid Organic Fertilizer), which is an organic fertilizer, is expected to improve the flowering phase of melon plants. This study aims to determine the appropriate combination of MKP fertilizer and amino acid LOF doses to improve flowering in melon plants. The study was conducted from April 2024 to July 2024. The research was conducted on farmers' land in Jatirejo Village, Nganjuk District, Nganjuk Regency. This study used a factorial experiment arranged in a Randomized Block Design (RBD) consisting of 2 factors. Factor I was the MKP fertilizer dose, consisting of 3 levels, namely M1 (5 g/plant), M2 (10 g/plant), M3 (15 g/plant), and factor II was the amino acid LOF dose consisting of 4 levels, namely A0 (control), A1 (50 ml/plant), A2 (100 ml/plant), A3 (150 ml/plant). The parameters used were the age of the first flower, the number of female flowers, the number of male flowers, and the total number of flowers. Data analysis was performed using ANOVA and a 5% significance level. The combination of 15 g/plant of MKP fertilizer and 100 ml/plant of amino acid LOF was the best treatment combination for increasing the number of male flowers and the total number of flowers on melon plants.
