Abstract

Produksi durian nasional mencapai 500–700 ribu ton per tahun, dengan Kabupaten Jember menyumbang sekitar 3.402 ton. Peningkatan produksi durian di Desa Klungkung Jember, menimbulkan permasalahan lingkungan akibat penumpukan limbah kulit durian yang sulit terurai. Limbah berpotensi mencemari udara, air, dan menghasilkan gas berbahaya seperti CH₄, NH₃, dan H₂S. Kegiatan bertujuan meningkatkan kapasitas dan kemandirian Kelompok Tani Hutan (KTH) Santoso. Metode pelaksanaan mencakup tahap persiapan, sosialisasi, pelatihan, implementasi, serta monitoring dan evaluasi berbasis partisipatif. Hasil kegiatan menunjukkan peningkatan signifikan pengetahuan peserta, dari skor rata-rata pre-test 4 menjadi post-test 7. Uji aktivasi menunjukkan bahwa jeruk nipis menghasilkan arang aktif dengan kejernihan tertinggi dibandingkan KOH dan NaOH. Dampak kegiatan meliputi pengurangan limbah organik, peningkatan pendapatan masyarakat, serta penguatan kesadaran lingkungan. Program ini terbukti efektif dalam mengimplementasikan teknologi tepat guna berbasis potensi lokal yang mendukung ekonomi sirkular dan kesejahteraan masyarakat secara berkelanjutan

Abstract

One type of coffee plant widely cultivated in Indonesia is robusta coffee. During cultivation, nursery practices are crucial for improving coffee quality and productivity. To obtain good Robusta coffee seedlings, fertilization is essential. The recommended fertilizer is organic, which is more environmentally friendly. Fertilizing with fermented golden apple snail extract supports sustainable agriculture. Therefore, the purpose of this study is to determine the concentration, frequency of treatment, and interaction on the growth of hybrid robusta coffee seedlings prolegitim (BP 42 x BP 358). The study was conducted in the field laboratory of Politeknik Negeri Jember for 5 months. This study used a non-factorial RBD with 7 treatments and 6 replications. K0 (Control-0% concentration); K1 (2.5% concentration + application every 4 weeks); K2 (5% concentration + application every 4 weeks); K3 (2.5% concentration + application every 2 weeks); K4 (7.5% concentration + application every 4 weeks); K5 (5% concentration + application every 2 weeks); K6 (7.5% concentration + application every 2 weeks). The observed variables include: Number of Leaves (pairs), Leaf Area Index, Stem Height, and Root Length. The experimental data were analyzed using ANOVA followed by the LSD test at the 5% significance level. The study found that the K2 treatment (5% concentration applied every 2 weeks) produced the optimal growth response, particularly in leaf area, seedling height, and root length.

Abstract

Sugarcane (Saccharum officinarum L.) is a strategic crop that is the primary raw material for sugar and has an important role in the economy. Domestic sugar production has not met national needs due to various constraints, such as low yield, poor seed quality, and soil damage due to inorganic fertilizers. The application of amino acids as organic fertilizers can potentially increase sugarcane productivity by improving plant metabolism and soil microbial activity. This study aimed to determine the effect of amino acid administration on generative growth and the Brix value of sugarcane plants (Saccharum officinarum L.). Varieties of sea lining. The research was implemented from February to June 2024 at the Lapang Laboratory, Department of Agricultural Production, Politeknik Negeri Jember. The method used in the study is the Group Random Design (RAK) method, which involves 1 factor, namely, Amino Acid organic fertilizer has four levels of amino acid dosage, namely A0 = Control (without amino acid administration), A1 = Amino Acid 250 ml/polybag, A2 = Amino Acid 500 ml/polybag and A3 = Amino Acid 750 ml/polybag. The data obtained from the research results was analyzed using ANOVA and then further tested using BNJ at the level of 5%. The results of the study found that the application of amino acids to sugarcane plants (Saccharum officinarum L.) had a real effect on the height of the plant at 188 HST, the stem diameter of 218 and 249 HST, and very real on the stem diameter of 188 HST and the root volume of 249 HST. However, the effect was not significant on the plant height of 218 HST, 249 HST, and Brix values.
