Abstract

Sampah domestik dari kegiatan rumah tangga yang tidak terkelola dengan baik mencemari lingkungan dan menimbulkan masalah kesehatan. Pengelolaan sampah secara komprehensif meliputi mengurangi (reduce), menggunakan kembali (reuse) dan mendaur-ulang (recycle) tidak hanya mengatasi permasalahan lingkungan tapi dapat mengubah nilai sampah dari barang yang tidak berharga menjadi produk komersial. Oleh karena itu, perlu dilakukan pemberdayaan terhadap ibu rumah tangga sebagai penghasil sampah domestik dalam pengelolaan sampah domestik. Permasalahan utama yang terjadi pada masyarakat sasaran adalah 1) kegiatan kelompok ibu-ibu belum banyak yang berhubungan dengan pemberdayaan masyarakat, 2) Sampah limbah rumah tangga di wilayah Kecamatan Medan Denai sebagian besar belum dimanfaatkan untuk pemberdayaan ekonomi, 3) sebagian besar anggota belum mempunyai pengetahuan, wawasan dan ketrampilan dalam intensifikasi dalam pemanfaatan dan pengelolaan sampah limbah rumah tangga.

Serdang Bedagai is the largest organic rice producing district in Sumatra Utara. The largest producer of organic rice in North Sumatra Province, the increase in production of organic rice in Serdang Bedagai Regency is directly proportional to the increase in organic rice land area. Increased consumer demand for organic rice does not mean that farmers get greater profits, because there are several market players in the process of distributing organic rice to consumers. The purpose of this study is to determine the pattern of marketing marketing channels, marketing functions, profit margins received by each marketing actor as well as Farmer's Share. and Farmer's Share of the organic rice supply chain in Serdang Bedagai Regency. This research uses a descriptive qualitative analysis approach with a snowball sampling method.

Abstract

In order to succeed in the development of agricultural sector in accordance with the Regulation of the Minister of Agriculture Number 67/Permentan/SM.050/12/2016 concerning Farmer Institutional Development, it is necessary to provide community service in the agricultural sector and plant cultivation as efforts to strengthen food self-sufficiency, especially during the Covid 19 pandemic. For this reason, we need to carry out community service activities for the production of liquid organic fertilizer using microorganism Bacillus cereus in Pantai Cermin Village, Tanjung Pura District. As we know Pantai Cermin Village, Tanjung Pura District, Langkat which about is 63.6 Km from Medan. In general, the majority of farmers own rice and corn areas and are members of the Gemah Ripah farmer group consisting of 30 farmers. From the results of dedication program, there are around 3000 hectares of rice and corn fields that have become a rice barn for the last 15 years, especially in Langkat Regency. Based on the results of the survey and partner interviews, several priority problems were obtained, including: a. There was a decrease in the selling price of corn in Langkat by Rp. 1,900,-/Kg from the selling price of corn in 2019 of Rp. 4,900,-/Kg to Rp. 3,000,-/Kg currently in Langkat; b. Rice farmers experienced a decrease in purchasing power of chemical compost during the Pandemic, because the price of solid organic compost from the Probiodek brand that functions as a decomposer of organic matter rose to Rp. 40,000,-/Kg; c. Farmers experienced a decline in purchasing power of chemical insecticides on the market; d. Farmers in Langkat currently do not have a knapsacksprayer and they only use 2 units of knapsacksprayer from government assistance to spray plant pests & diseases and this tool is used interchangeably for all farmer groups; e. Farming management is carried out in a simple and conventional way, namely using local F1 seeds (yield) from the previous corn harvest); f. Rice harvesting as well as shelling corn use a simple method of rice mill machine. In order to develop the potential of rice and corn barns, it is necessary to strengthen the independence of farmers through community dedication program (PKM) training in the production of liquid organic fertilizer using microorganism Bacillus cereus from Ristekdikti. The focus is to develop production of liquid organic fertilizer as an alternative to chemical fertilizers and chemical insecticides. The use of microorganisms Bacillus cereus is especially useful for facilitating the decomposition of organic matter in liquid fertilizer solutions so that it is more easily absorbed by plants as fertilizer and insecticide, as well as assisting and motivating partners to continuously continue producing liquid organic fertilizers because it saves costs in purchasing chemical fertilizers and pesticides in the future so as to create economic independence for partners. This will certainly improve the economy of farmer group partners so that life can be more prosperous. All of these activities aim to foster independence in partners when the program ends. It is hoped that food self-sufficiency can be realized that is free from residues of chemical fertilizers and insecticides so that environmentally sustainable agriculture can be realized.

Abstract

Jamur tiram merupakan bahan makanan bernutrisi dengan kandungan protein tinggi, kaya vitamin dan mineral, rendah karbohidrat, lemak dan kalori. Jamur ini memiliki kandungan nutrisi seperti vitamin, fosfor, besi, kalsium, karbohidrat, dan protein. Media yang umum dipakai untuk membiakkan jamut tiram adalah serbuk gergaji kayu. Permasalahan pada mitra mempunyai kendala usaha pada kapasitas produksi hanya 120 baglog/hari dan ini belum maksimal untuk memenuhi permintaan pasar baglog di sekitar Jepara. Selain itu proses pembuatannya masih sangat konvensional baik pada proses pemadatan, sterilisasi tanpa kontrol suhu uap panas, dan proses inokulasi kurang steril karena dilakukan pada ruang terbuka serta tempat penyimpanan baglog yang tidak efisien karena hanya ditaruh dilantai rumah tinggal. Solusi dan target luaran yang diberikan untuk mitra adalah penyuluhan manajemen usaha yang baik, pembuatan alat pemadatan baglog mekanis, pembuatan alat sterilisasi yang lebih besar kapasitasnya dan dilengkapi dengan kontrol suhu otomatis, dan ruangan steril untuk inokulasi. Tujuan Program pengabdian ini adalah pengabdi membantu usaha budidaya jamur tiram ditengah pandemi covid 19 di Kelurahan Denai, Kecamatan Medan Denai, Kota Medan. Kegiatan pelatihan ini dilakukan dengan pembekalan, demonstrasi cara budidaya jamur tiram putih dimulai dengan persiapan media tanam, pencampuran media, fermentasi, pengisian media dalam baglog, sterilisasi, inokulasi bibit, inkubasi, pemeliharaan dan panen serta pemberian alat produki baglog.

Abstract

Purpose: This study evaluates the economic feasibility and assesses the financial risks associated with smallholder patin (Pangasius hypophthalmus) aquaculture in Kabupaten Kampar, Riau Province, Indonesia, to provide evidence-based recommendations for sustainable aquabusiness development. Materials and Methods: A descriptive-quantitative research design was employed with 60 smallholder patin farmers selected through purposive sampling. Data collection involved structured interviews, production record audits, financial document analysis, and direct pond observations. Economic feasibility was evaluated using Net Present Value (NPV), Benefit-Cost Ratio (BCR), Internal Rate of Return (IRR), and Payback Period (PP) at a 10% discount rate. Risk assessment incorporated Coefficient of Variation (CV), sensitivity analysis, Monte Carlo simulation (10,000 iterations), and scenario analysis. Statistical analysis was performed using SPSS 26. Results: The average NPV was IDR 127,450,000 (USD 8,497), BCR was 1.34, IRR was 24.6%, and PP was 2.8 years, indicating economic viability. Risk analysis revealed a CV of 0.42, suggesting moderate income variability. Monte Carlo simulation showed a 73.4% probability of positive returns. Sensitivity analysis identified feed cost (elasticity coefficient: -0.68) and market price (elasticity coefficient: 0.82) as critical risk factors. Under pessimistic scenarios, 31.7% of farms showed negative NPV. Conclusions: Patin aquaculture demonstrates economic feasibility under current market conditions, but faces significant risks from feed cost fluctuations and price volatility. Risk mitigation strategies including feed cost management, market diversification, and insurance mechanisms are recommended for sustainable development.

Abstract

TM. Ali Muda is a North Sumatran astronomy figure who came from Aceh. His work and contribution in the field of astronomy is beyond doubt. His thinking in the matter of determining the beginning of the month is to combine calculations and field observations. However, the tendency of his calculation (hisab) is also quite dominant which is shown by his analysis in various issues of celestial jurisprudence. Meanwhile, in the matter of matlak and Eid al-adha, the hajj-related services whose implementation is only in Mecca, according to him, are obliged to hold on to the matlak of Mecca, while those whose implementation is not only in Mecca are obliged to hold on to their respective matlak
