Abstract

Abstrak. Tujuan penelitian adalah untuk mengetahui : efektifitas pemberian Urea dan EM4 terhadap dekomposisi tanda kosong kelapa sawit.Rancangan yang digunakan dalam penelitian ini adalah Rancangan Acak Kelompok (RAK) dengan 4 ulangan. Perlakuan terdiri atas : 200 kg decenter solid, 220 kg TKKS, 220 kg TKKS + 500 g urea, 220 kg TKKS + 500 g urea + 40 mL EM4, dan 220 kg TKKS +40 mL EM4.Hasil penelitian menunjukkan aplikasi tandan kosong kelapa sawit dan decenter solid berperan dalam merangsang pertumbuhan akar aktif, dan memperbaiki warna daun kuning menjadi hijau jika diaplikasikan pada tanah tandus. Pemberian urea dan EM4 dapat mempercepat pelapukan tandan kosong kelapa sawit. Abstract.The purpose of this study was to determinethe effect of giving Urea and EM4 to the decomposition of oil palm empty signs. The design used in this study was a randomized block design (RBD) with 4 replications. The treatments consisted of: 200 kg solid decenter, 220 kg TKKS, 220 kg TKKS + 500 g urea, 220 kg TKKS + 500 g urea + 40 mL EM4, and 220 kg TKKS + 40 mL EM4. The results showed the application of oil palm empty fruit bunches and solid decenter plays a role in stimulating the growth of active roots, and improving the color of yellow leaves to green when applied to barren soils. The provision of urea and EM4 can accelerate the weathering of oil palm empty fruit bunches.

Abstract

The prospect of cauliflower or in its foreign language cauliflower in east Kalimantan is very promising. The supply of cauliflower at this time is very dependent on outside the East Kalimantan region, namely Java and Sulawesi. The efforts made to meet the needs are to increase production by improving intensive cultivation techniques. The productivity of cauliflower plants can be increased by providing micronutrients and using suitable varieties. The study aims to determine the effect of mikro fitomic and variety nutrients on the growth and production of cauliflower plants. This study was compiled in a Randomized Group Design (RAK) with a 4 x 2 factorial trial with 4 repeats. The first factor is the concentration of mikro fitomic fertilizer (F), which consists of 4 levels: F0: control, F1: 1.5 ml/litre of water, F2: 2.5 ml/litre, F3: 3.5 ml/litre water. The second factor is the variety, which consists of 4 levels V2: PM 126 variety. Fitomic micro fertilizer has significantly affected the growth and production of Brassica oleracea. The crop/plant weight of 884.38 grams was achieved at the optimal concentration of micro-fitomik fertilizer 3.5 ml/litre of water. The Brassica oleracea variety had a significantly affected diameter, plant/plant weight, and plant/plot weight. Plant production/hectare of the PM 126 variety was higher than the production of the Orient variety. The interaction between the concentrations of micro-fitomic fertilizers and the two types of varieties was not significantly different in growth and production. Recommendations for the application of micro-fitomic to B.oleracea plants are applied at a concentration of 3.5 ml/litre of water. PM126 and Orient varieties are suitable for cultivation in the lowlands of East Kalimantan.

Abstract

Tujuan Penelitian untuk mengetahui pengaruh pupuk NPK Mutiara dan POC Nasa serta Interaksi kedua perlakuan tersebut terhadap pertumbuhan dan produksi bawang merah (A. ascalonicum L.). Penelitian dilaksanakan dilahan terletak di Jl. Flamboyan, Kelurahan Loabuah, Kecamatan Sungai Kunjang, Kota Samarinda. Penelitian ini dilaksanakan selama 4 bulan, mulai pada Maret hingga Juni 2022. Penelitian menggunakan Rancangan Acak Kelompok dengan percobaan faktorial 4x4 yang terdiri dari 3 ulangan. Faktor Pertama adalah NPK Mutiara (M) yang terdiri dari 4 taraf yaitu M0 (tanpa perlakuan), M1 (3 g/polybag), M2 (5 g/polybag), dan M3 (7 g/polybag). Faktor kedua adalah POC Nasa (N) yang terdiri dari 4 taraf yaitu N0 (tanpa perlakuan), N1 (8 mL/L air), N2 (16 mL/L air), dan N3 (24 mL/L air). Hasil penelitian pada perlakuan pupuk NPK Mutiara pada parameter tinggi tanaman 15 HSP, jumlah anakan, berat basah serta berat kering tidak berpengaruh nyata. Namun tinggi tanaman 45 HSP berpengaruh sangat nyata. Hasil penelitian pada perlakuan POC Nasa pada parameter tinggi tanaman 15 HSP 45 HSP, berat basah serta berat kering tidak berpengaruh nyata. Namun pada jumlah anakan berpengaruh nyata. Interaksi kedua perlakuan pupuk tersebut tidak berpengaruh nyata terhadap semua parameter. Pupuk NPK Mutiara dengan dosis 4,2 gr/polybag memberikan hasil terbaik pada pertumbuhan dan produksi bawang merah. POC Nasa dengan dosis 13 mL/L air memberikan hasil terbaik pada pertumbuhan dan produksi bawang merah. Kata Kunci : Bawang merah, NPK Mutiara, POC Nasa
