Abstract

The purpose of this study is to obtain an efficient combination of planting media for the growth and yield of vegetables, especially the Red Lettuce plant (Lactuca sativa var Red rapids). This research was carried out at the Greenhouse of the Faculty of Agriculture, Sam Ratulangi University from July to September 2022. This study used a non-factorial Complete Randomized Design (RAL) which was carried out with 5 treatments and 4 tests. So there are 20 experimental units. M0 (Soil without combination) as a control, M1(Combination of Soil and Husk), M2 (Combination of Soil and Husk Charcoal), M3(Combination of Soil and Sawdust) and M4 (Combination of Soil and Burn Sawdust). The results showed that the M4 treatment (Combination of Soil and Burn Sawdust) gave the best plant height with an average of 18.13 cm, the average number of leaves was 19.00 strands, the average brangkasan weight was 97.75 grams, the wet weight of the roots averaged 3.75 grams and based on the Fingerprint Analysis had a noticeable influence on the number of leaves, leaf width and weight of the Red Lettuce plant (Lactuca sativa var. Red rapids). Keywords: Growing media, combination, Lactuca sativa var. Red rapids Abstrak Tujuan dari penelitian ini adalah untuk mendapatkan kombinasi media tanam yang efisien untuk pertumbuhan dan hasil sayuran khususnya tanaman Selada Merah (Lactuca sativa var Red rapids). Penelitian ini dilaksanakan di Rumah Kaca Fakultas Pertanian Universitas Sam Ratulangi pada bulan Juli sampai September 2022. Penelitian ini menggunakan Rancangan Acak Lengkap (RAL) non faktorial yang dilakukan dengan 5 perlakuan dan 4 pengujian. Jadi terdapat 20 satuan percobaan. M0 (Tanah tanpa kombinasi) sebagai kontrol, M1 (Kombinasi Tanah dan Sekam), M2 (Kombinasi Tanah dan Arang Sekam), M3 (Kombinasi Tanah dan Serbuk Gergaji) dan M4 (Kombinasi Tanah dan Serbuk Gergaji Bakar). Hasil penelitian menunjukkan bahwa perlakuan M4 (Kombinasi Tanah dan Serbuk Gergaji Bakar) memberikan tinggi tanaman terbaik dengan rata-rata 18,13 cm, rata-rata jumlah daun 19,00 helai, berat brangkasan rata-rata 97,75 gram, berat basah akar rata-rata 3,75 gram dan berdasarkan Analisa Sidik Jari berpengaruh nyata terhadap jumlah daun, lebar daun dan berat tanaman Selada Merah (Lactuca sativa var. Red rapids). Kata kunci: Media tanam, kombinasi, Lactuca sativa var. Red rapids

Abstract

The purpose of this study was to determine the quality of irrgation water in Kauditan 1 I Village. Based on PP No. 22/2021 Concerning the Implementation of Environmental Protection and Management, Appendix VI concerning Class II, III and IV National Water Quality Standards for irrigating plantations and Sodium Adsorption Ratio (SAR) values in Kauditan District, North Minahasa Regency. This research was carried out for ± two months (2 months), from July to September 2022 in the village of Kauditan I, Kauditan District, then continued with analysis in the Manado Baristand Laboratory. The results showed that Total Dissolved Solid (TDS), Total Suspended Solid (TSS), Nitrate-N (NO3-N), Phosphate (PO4-P), Boron (B), Chloride (Cl) and pH met the National Water Quality Standard requirements. Class II, III and IV Designation for Irrigating Plantations Based on Government Regulation No. 22 of 2021 concerning Implementation of Environmental Protection and Management, Appendix VI. River Water and the Like. Electrical Conductivity meets Ayers & Westcot irrigation water quality requirements. (1985) with good category. And the value of Sodium Adsorption Ratio (SAR) is <10 with a good category. Keywords: Water quality, Irrigation, Rice fields, National Water quality standard Abstrak Tujuan penelitian ini adalah untuk mengetahui kualitas air irigasi di Desa Kauditan I Berdasarkan PP No. 22/2021 Tentang Penyelenggaraan Perlindungan dan Pengelolaan Lingkungan Hidup, Lampiran VI tentang Baku Mutu air Nasional Kelas II, III dan IV peruntukan mengairi pertanaman dan nilai Sodium Adsorption Ratio (SAR) di Kecamatan Kauditan Kabupaten Minahasa Utara. Penelitian ini dilaksanakan selama ± dua bulan (2 bulan), mulai Juli hingga September 2022 di desa Kauditan I Kecamatan Kauditan, kemudian dilanjutkan dengan analisis di Laboratorium Baristand Manado. Hasil penelitian menunjukan Total DIssolved Solid (TDS), Total Suspended Solid (TSS), Nitrat-N (NO3-N), Fosfat (PO4-P), Boron (B), Klorida (Cl) dan pH memenuhi syarat Baku Mutu Air Nasional Kelas II, III dan IV Peruntukan Untuk Mengairi Pertanaman Berdasarkan Peraturan Pemerintah No. 22 Tahun 2021 Tentang Penyelengaraan Perlindungan Dan Pengelolaan Lingkungan Hidup, Lampiran VI. Air Sungai dan Sejenisnya. Daya Hantar Listrik memenuhi persyaratan kualitas air irigasi Ayers & Westcot. (1985) dengan kategori baik. Serta nilai Sodium Adsorption Ratio (SAR) adalah <10 dengan kategori baik. Kata kunci: Kualitas air, Irigasi, Persawahan, Baku Mutu Air Nasional
