Pakchoy (Brassica rapa L.) merupakan sayuran bernilai ekonomis tinggi yang membutuhkan ketersediaan unsur hara optimal untuk pertumbuhannya. Penelitian ini bertujuan untuk membandingkan efektivitas pupuk kompos limbah rumah tangga, pupuk kotoran ayam, dan pupuk Ponska terhadap pertumbuhan tanaman pakchoy. Penelitian menggunakan Rancangan Acak Lengkap (RAL) dengan 3 perlakuan dan 4 ulangan. Perlakuan terdiri dari: A (pupuk kompos limbah rumah tangga 100 g/lubang tanam), B (pupuk kotoran ayam 100 g/lubang tanam), dan C (pupuk Ponska 2 g/lubang tanam). Parameter yang diamati meliputi tinggi tanaman, jumlah daun, dan berat basah tanaman. Data dianalisis menggunakan ANOVA dan dilanjutkan dengan uji BNT 5%. Hasil penelitian menunjukkan bahwa perlakuan pupuk berpengaruh sangat nyata terhadap berat basah (F-hitung 17,4803 > F-tabel 1% = 4,98) dan berpengaruh nyata terhadap tinggi tanaman serta jumlah daun (F-hitung 9,406 > F-tabel 5% = 3,16). Pupuk kompos limbah rumah tangga memberikan hasil terbaik dengan rata-rata tinggi tanaman 23,93 cm, jumlah daun 23,93 helai, dan berat basah 263,45 gram, berbeda nyata dengan pupuk kotoran ayam dan pupuk Ponska. Peningkatan berat basah mencapai 88% dibandingkan perlakuan lainnya. Pupuk kompos limbah rumah tangga dapat menjadi alternatif pupuk organik yang efektif dan ramah lingkungan untuk budidaya pakchoy.

Tomatoes are an important food for humans whose production and price must be maintained so that the commodity remains available to humans. The objectives of the study are (i) analyzing the cost structure of tomato farming in Minahasa district, Indonesia, (ii) analyzing strategies to increase the competitive advantage of tomato farmers based on the cost structure of tomato farming with a business intelligence (BI) approach in Minahasa district, Indonesia and (iii) provide recommendations for the concept of tomato farming technology based on improving the structure of tomato farming costs in Minahasa district, Indonesia. This research uses a quantitative approach with the BI method and was carried out in the tomato production center of Minahasa district, North Sulawesi. The results found that (i) the production cost structure of Apple Tomato farming, namely variable costs of Rp 53,600,054.44 / ha or 78.74 percent and fixed costs of Rp 14,475,057.00 / ha or 21.26 percent. Based on cost structure, the variable cost that can be reduced is human labor cost and the fixed cost that can be reduced is stake cost. The recommended innovations that can be applied are using tractors to replace human labor to make beds, and replacing bamboo stakes with plastic pipes. This innovation can increase the profit of tomato farming from Rp 99,122,272.83 per ha to Rp 108,456,162.83 or an increase of Rp 9333890.00 (9.42%) per ha and the BEP price from Rp 2,300 per kg to Rp 1,987.82 per kg or reduce by Rp 312.18 (13.57%) per kg.

Chicken manure improves soil fertility by adding organic matter and enhancing soil structure, while NPK fertilizer provides fast, readily available nutrients. This study compared both fertilization strategies in rice and corn farming in Tomohon City, focusing on profitability, production costs, environmental impacts, and factors influencing farmers’ choices. A comparative observational method was used with 120 farmers selected through simple random sampling. Results showed that NPK fertilizer generated higher profits in corn farming, but no significant difference was found in rice. Meanwhile, chicken manure resulted in more cost-efficient production. Environmentally, chicken manure improved soil quality by increasing pH toward neutral, raising organic carbon (>2.7%), enhancing cation exchange capacity, and reducing nitrate residues and exchangeable aluminum—key indicators of long-term soil health in volcanic soils. In contrast, NPK fertilizer contributed to soil degradation, including declining pH, reduced organic matter, and accumulation of nitrate and exchangeable aluminum, which may harm root development and increase groundwater contamination risks. Farmers’ fertilizer choices are influenced by technical, economic, institutional, and socio-cultural factors. Overall, the findings highlight the importance of integrated fertilization strategies combining organic and inorganic inputs to balance short-term profitability and long-term sustainability. Policy efforts should focus on promoting integrated nutrient management, strengthening extension services, and providing incentives for environmentally sustainable practices to improve farm outcomes while preserving soil health.
