Abstract

Limitations in productivity and adverse impacts of chemical fertilizers highlight the need for sustainable solutions in soybean cultivation in Indonesia. This study aims to evaluate the effectiveness of organic fertilizers as an alternative to chemical fertilizers in sustainable agriculture-based soybean cultivation. The experimental method employed a Completely Randomized Design (CRD) with six treatments: control (no fertilizer), chemical fertilizer, goat manure, compost, biochar, and a combination of POC + compost. The parameters observed included plant height, number of effective root nodules, yield components (number of pods, weight of 100 seeds, yield per polybag), as well as changes in soil chemistry after harvest. The results showed that the treatment of goat manure (P2) and a combination of POC + compost (P5) gave the best results in improving soybean growth and yield. Both also showed significant improvements in soil pH, C-organic content, total nitrogen, and availability of P and K. In addition to increasing crop yields, organic fertilizers have also been proven to support increased soil microbial activity through the formation of effective root nodules. Thus, organic fertilizers have proven to be an effective and environmentally friendly alternative in replacing chemical fertilizers. The use of organic fertilizers can promote productive, efficient, and sustainable soybean farming.

Abstract

This study aims to analyze the contribution of the diversity of biota in the waters of Toba Lake to the richness of Indonesia's biota. Research is needed to analyze the diversity of Lake Toba water biota. In order to achieve this goal, data and information collected regarding the contribution of the diversity of Lake Toba waters to the richness of Indonesia's biota is used. Verification of the data and information obtained was carried out through literature study, document analysis, interviews and filling out questionnaires. The results showed that in the waters of the lake there are endemic fish species whose existence is currently almost extinct, namely Batak fish or "ihan" (Neolissochillus thienemanni) consisting of two species, namely: Lissochilus sumatranus and Labeobarbus soro. There are various types of aquatic plants such as various types of algae and water hyacinth. Apart from that, there are also various species of molluscs such as freshwater snails and clams as well as other aquatic animals such as frogs and eels. The aquatic biota of Lake Toba has an important role in maintaining the balance of the ecosystem and providing resources for the people around the lake and contributing to Indonesia's Biota Wealth.

Abstract

Penelitian ini bertujuan untuk meneliti pengaruh dari aplikasi biochar sekam padi dan pupuk kandang sapi yang diduga aplikasinya secara perlakuan tunggal mauppun kombinasinya akan memberi pengaruh terhadap pertumbuhan dan produksi tanaman baby corn (Zea mays saccaratha L.) dimana perlakuan yang dilakukan adalah untuk mendapatkan data mengenai untuk mengetahui pengaruh aplikasi biochar sekam padi dan pupuk kandang sapi terhadap pertumbuhan dan produksi tanaman baby corn (Zea mays saccaratha L.) pada tanah Ultisol Simalingkar. Penelitian ini dilaksanakan di Kebun Percobaan Fakultas Pertanian Universitas HKBP Nommensen Medan di Simalingkar, Kecamatan Medan Tuntungan.  Lahan penelitian terletak pada ketinggian  sekitar  ±33 meter diatas permukaan air laut (mdpl) dengan keasaman  (pH) tanah 5,5-6,5 dan jenis tanah Ultisol, tekstur tanah pasir berlempung (Lumbanraja dkk., 2023).  Penelitian ini dilaksanakan pada bulan Januari 2023 sampai Maret 2023.  Bahan yang digunakan dalam penelitian ini adalah benih Jagung manis varietas Secada F1, Pupuk Kandang Sapi, Biochar sekam padi , Fungisida Dithane M-45, Insektisida Decis 25 EC, Ridomil Gold MZ 4, Fungisida Acrobat dan air.Pada hasil uji penelitian diperoleh data pengamatan parameter pertumbuhan tanaman, memperlihatkan bahwa perlakuan biochar sekam padi berpengaruh dengan  nyata pada pengamatan tinggi tanaman pada umur 2 MST dan 3 MST saja, sedangkan untuk minggu selanjutnya pengaruh perlakuan terhadap parameter ini tidak berbeda nyata

Abstract

Canada, amid the growing need for sustainable food production. The background of this research focuses on the challenges of modern agriculture in the efficient use of fertilizers and their impact on the environment. The purpose of the study was to examine the extent to which smart fertilization technology can improve agricultural yields while reducing fertilizer use and environmental impact. The research method used is a quantitative approach with field experiments involving farmers in five major Canadian provinces, using soil and weather sensors to collect data in real-time. The results of the study show that smart fertilization technology is able to increase crop yields by up to 22% and reduce fertilizer use by up to 18%, as well as reduce environmental impact by 9-12%. The conclusion of the study is that smart fertilization technology has great potential in improving agricultural efficiency and maintaining environmental sustainability in Canada. However, more research is needed to understand the long-term impact and ensure equitable access to these technologies across the region.
