Analysis Of Irrigation Water Quality For Fields In Treman Village, North Minahasa Kauditan Regency. Ekoton   5. 28-35. This study aims to determine the quality of irrigation water in rice fields in Treman Village, Kauditan District, North Minahasa. This research was conducted for two (2) months, namely from March to April 2023. This research was conducted using purposive sampling method, the sampling technique is Composite. Research samples were taken at three points, namely the Primary Canal, Secondary Canal, and Tertiary Canal. Samples were taken as much as 4500 mL in each Canal, then analyzed at the Manado Industrial Research and Standardization Center Laboratory. The data obtained was analyzed using Bar Chart Statistics. The research shows that the Irrigation Water Quality of Rice Field Areas in Treman Village, Kauditan District, North Minahasa is still classified as very good because it meets the requirements as irrigation water according to Water Quality Of Irrigation based on Ayers & Westcott (1995), and there is no pollution based on Government Regulation No. 22 of 2021 concerning the Implementation of Protection and Management of Irrigation Water. Keywords: Quality of irrigation water, Sodium Absorption Ratio

Abstract

This Zingiberaceae plant is widely used as medicine, including temulawak. Because curcuma (C.xanthorrhiza) is a medicinal plant that has many benefits and includes plants needed in large quantities compared to other medicinal plants. Traditionally rhizomes Temulawak is used to treat stomach ailments, liver disorders, constipation, diarrhea, dysentery, fever, hemorrhoids, hypotriglyceridaemic, and anti-inflammatory. Study about plant Curcuma local ignite still not enough researched so that not yet get information compounds which contained in the local curcuma of North Sulawesi for the development for biopharmaceutical development, mapping in the distribution of plants, ecology, plant conservation and protection to maintain local wisdom. Histochemical Test is a method to determine the content of chemical compounds in a plant tissue qualitative. Testing can be done by adding a special reagent or solution to the incision organ plant and will give color which Specific. Activity study this will test curcumin compound group on local ginger from North Sulawesi by histochemical method. research that done is study non experiment with design descriptive qualitative. The results showed that North Sulawesi local white temulawak powder contained curcumin in a sample with a sample weight of 0.10 g at a sample spotting volume of 20 µl with a sample spotting volume of 2040 nanograms, curcumin levels were <0.10 nanograms/mg. Curcumin biosynthesis is influenced by site conditions, agro-climate, genotype, and plant cultivation.

Abstract

Jagung (Zea mays L) adalah salah satu tanaman pangan yang merupakan sumber karbohidrat utama kedua setelah beras. Metode modifikasi lingkungan mikro dapat meningkatkan produksi jagung. Tujuan dari penelitian ini adalah untuk mengetahui pengaruh waktu pemangkasan daun di bawah tongkol terhadap tingkat produksi jagung. Studi ini dilakukan di Desa Padang, Kecamatan Bintauna, Kabupaten Bolaang Mongondow Utara, Sulawesi Utara, dari Desember 2023 hingga April 2024. Metode penelitian adalah rancangan acak kelompok dengan lima perlakuan dan tiga kali ulangan. Penelitian menemukan bahwa perlakuan pemangkasan daun di bawah tongkol adalah tanpa pemangkasan (P0), pemangkasan 60 hari setelah tanam (P1), pemangkasan 70 hari setelah tanam (P2), pemangkasan 80 hari setelah tanam (P3) dan pemangkasan 90 hari setelah tanam. Hasil penelitian menunjukkan bahwa komponen produksi pada panjang tongkol, yaitu ukuran tongkol 19,26 cm dengan diameter 5,00 cm, berat biji sekitar 241.92 g, dan jumlah biji sekitar pertongkol 617.42, meskipun berdasarkan hasil analisis sidik ragam, pengaruh tanaman jagung hanya terbatas pada panjang dan diameter tongkol.

Abstract

This study aims to analyze the spatial distribution of the impact of nitrogen residue/diversification on the diversity of aquatic biota and contribute to the management of aquatic ecosystems as a source of life. Water quality sampling was carried out by grab sampling with water quality parameters measured including total nitrogen (TN), ammonia (NH₃), nitrate (NO₃⁻), and nitrite (NO₂⁻). TN analysis was carried out using the Total Kjeldahl Nitrogen (TKN), nitrate, and nitrite calculation methods. NH₃ was measured using the Flow Injection Analysis method, while NO₃⁻ was analyzed using the Cadmium Reduction Method and NO₂⁻ with the colorimetric method.Plankton sampling was done by filtering 20 liters of water from the surface layer using a 2-liter bucket. The plankton species diversity index was calculated using the Shannon-Wiener Index method. The effect of environmental factors on nitrogen chemical fertilizer residues in each research location was analyzed using the Principal Component Analysis (PCA). The results showed an increase in ammonia and nitrite residues followed by a decrease in total nitrogen and nitrate concentrations. Seven classes and 22 plankton species were identified, consisting of 18 phytoplankton species and four zooplankton species. The dominant plankton came from Cyanophyceae, Bacillariophyceae, and Chlorophyceae. The highest plankton species diversity index was recorded in Irrigation IX and VII. Based on the study results, plankton diversity at the research location is included in the moderate category. The main environmental factors that influence the presence of plankton in irrigation channels are the concentration of nitrate and nitrogen in the water.
