Abstract

This study assesses the impact of adding phosphate and boron in a mixed liquid fertilizer (MLF)  on the growth and yield of red chili plants cultivated in a subsoil environment. The experiment was conducted to comprehend how these nutrients affect the performance of red chili plants, particularly when cultivated in less ideal conditions such as subsoil, a remnant of excavation for brick production. The research was carried out at the Ciparanje Garden of the Faculty of Agriculture, Universitas Padjadjaran. The research design employed a Randomized Completely Block Design with the following treatments: A = Control (degraded soil without fertilizer), B = 0% MLF + 1 NPK, C = 0.25% MLF + 1 NPK, D = 0.50% MLF + 1 NPK, E = 0.75% MLF + 1 NPK, F = 1.00% MLF + 1 NPK, G = 0.5% MLF + 3/4 NPK, H = 0.5% MLF + 1/2 NPK, I = 0.5% MLF + 1/4 NPK, J = 0.5% MLF + 0 NPK, and K = 1 NPK in normal soil. The results revealed that the addition of phosphate and boron in MLF significantly influenced the growth and yield of red chili in subsoil conditions. The recommended MLF concentration was 0.75%, alongside the standard NPK dose. These findings provide crucial insights for the development of more efficient and sustainable agricultural practices, especially in challenging soil conditions like subsoil, where nutrient availability can be a determining factor for agricultural success.

Abstract

Effective organic waste decomposition is vital for sustainable waste management and agricultural productivity. This study investigates the efficacy of ASEM-7—a newly developed decomposer comprising a consortium of seven microorganisms—in accelerating the composting process and enhancing compost quality across various types of organic waste. Five treatment groups were evaluated: paddy straw; animal manure; fruit and vegetable waste; a mixture of fruit and vegetable waste with straw; and a combination of fruit, vegetable waste, straw, and manure. During the decomposition process, key physicochemical parameters— including pH, temperature, moisture content, organic carbon (C-organic), total nitrogen (N-total), and the carbon-to-nitrogen (C/N) ratio—were systematically monitored. The results demonstrated that ASEM-7 significantly enhanced composting efficiency compared to both EM-4 and control (no-decomposer) treatments, achieving optimal pH stabilization (7–8) at a faster rate. Additionally, ASEM-7 reduced moisture content and C/N ratios more effectively, indicating a higher degree of compost maturity. Compost treated with ASEM-7 also exhibited the lowest levels of organic carbon, reflecting superior decomposition efficiency. Although temperature levels remained below the threshold required for effective pathogen elimination, microbial activity successfully facilitated nutrient recycling. The microbial consortium—comprising Bacillus sp., Lactobacillus sp., and Trichoderma sp.—demonstrated high efficacy in degrading recalcitrant organic materials such as straw and manure, thereby improving the compost's nutrient composition. By meeting key compost quality standards—organic carbon (≥15%), total nitrogen (≥0.5%), and a C/N ratio of 15–25—ASEM-7 effectively converts organic waste into high-quality compost. These findings underscore the importance of tailored microbial consortia in advancing sustainable waste management practices and enhancing soil fertility.

Abstract

Studi ini bertujuan untuk menganalisis manifestasi kearifan lokal masyarakat pesisir Aceh yang tercermin dalam tradisi Kenduri Laut, dengan fokus pada implikasinya terhadap ketahanan budaya. Pendekatan penelitian kualitatif dengan pendekatan library research digunakan untuk mengumpulkan data melalui studi literatur, dan analisis dokumen. Penelitian ini berupaya mengeksplorasi bagaimana tradisi Kenduri Laut, sebagai praktik budaya yang diwariskan secara turun-temurun, berkontribusi pada pelestarian nilai-nilai luhur dan keberlanjutan lingkungan di wilayah pesisir Aceh. Temuan penelitian menunjukkan bahwa Kenduri Laut berfungsi sebagai wahana konservasi lingkungan laut melalui nilai-nilai yang terintegrasi dalam ritualnya. Tradisi ini mengedukasi masyarakat mengenai pentingnya menjaga ekosistem laut dari praktik-praktik destruktif seperti pengeboman ikan dan pencemaran laut. Kenduri Laut berperan signifikan dalam memperkuat ketahanan budaya masyarakat pesisir Aceh, tercermin dalam partisipasi masyarakat dan pemerintah daerah dalam upaya pelestarian melalui Festival Khadori Laot. Program-program berfokus melestarikan tradisi, dan mempromosikan kesadaran pentingnya menjaga keseimbangan ekosistem laut. Konsep ketahanan budaya dalam konteks dioperasionalkan melalui komitmen masyarakat dan pemerintah untuk memelihara warisan budaya. Kemudian Dinas Pariwisata dan Kebudayaan setempat mengimplementasikan visi dan misi untuk memperkuat ketahanan budaya Kenduri Laut melalui adaptasi perayaan menyesuaikan dinamika zaman sehingga memberikan arsip digital. Studi ini menyimpulkan bahwa Kenduri Laut representasi kearifan lokal religious berkontribusi pada konservasi lingkungan dan ketahanan budaya masyarakat pesisir Aceh melalui electronic recordkeeping untuk menjaga eksistensi budaya masyarakat setempat.

Abstract

Fertilization is a key factor in enhancing crop productivity, primarily through the provision of essential nutrients. The application of compound fertilizers containing macronutrients, either as an alternative or a complement to single-nutrient fertilizers, is expected to improve fertilization efficiency and support sustainable crop yields. This study aimed to evaluate the effect of combining macronutrient NPK compound fertilizer with single-nutrient fertilizers—nitrogen (N), phosphorus (P), and potassium (K)—on plant growth and yield, as well as to determine the optimal dosage. The experiment was conducted from December 2024 to April 2025 using a randomized complete block design (RCBD) with nine treatments and three replications. The treatments included: a control (no fertilizer), single NPK fertilizers (300 kg/ha Urea, 150 kg/ha SP-36, 100 kg/ha KCl), combinations of NPK with compound fertilizer at different dosages (½, 1, and 1½), and compound fertilizer alone (4 L/ha). The results revealed that the combination of N, P, and K with compound fertilizer significantly enhanced plant growth and yield. Among all treatments, treatment E (NPK + 1½ doses of compound fertilizer) resulted in the highest maize yield

Abstract

Masalah limbah organik di Indonesia menjadi perhatian serius karena berkontribusi terhadap pencemaran lingkungan dan kesehatan masyarakat. Penelitian ini bertujuan untuk mengembangkan formula Super Dekomposer Cair Ramah Lingkungan yang berfungsi sebagai pengurai sampah organik. Formula ini mengombinasikan mikroorganisme seperti Streptomyces sp, Aspergillus sp, Pseudomonas sp, Saccharomyces sp, Lactobacillus sp, Trichoderma sp, dan Penicillium sp. Metode yang digunakan pada penelitian ini meliputi pengujian kompatibilitas dan stabilitas. Hasil menunjukkan bahwa formulasi yang dirancang secara kompatibilitas, ketujuh mikroorganisme yang tergolong bakteri dan jamur dapat hidup berdampingan, saling kompatibel, dan mampu bersinergi sedangkan secara stabilitas, ketujuh mikroorganisme tersebut memiliki aktivitas biologis yang baik setelah disimpan selama satu bulan, memiliki aktivitas mikroorganisme yang baik ditandai dengan perubahan pH menjadi asam selama proses fermentasi dan mampu mendegradasi bahan-bahan organik secara optimal. Dapat disimpulkan bahwa produk ini berpotensi sebagai alternatif dekomposer yang efisien dan ramah lingkungan, terutama bagi petani skala kecil dan rumah tangga serta dapat mendukung pertanian berkelanjutan dan sistem pengelolaan limbah yang lebih efisien.
