This study aims to determine the nutrient levels of Liquid Organic Fertilizer (POC) Wastewater and Lemongrass Wastewater and soil nutrient status sub-optimal land after incubation for 21 days. Sub-optimal land is land that naturally has low productivity, therefore it is necessary to add nutrients in both organic and inorganic fertilizers to change nutrient status in the soil. Organic fertilizer in liquid form is one type of fertilizer that can facilitate the absorption of nutrients. Tofu wastewater has an unpleasant odor, one of the efforts that will be made to reduce the odor is by adding fragrant lemongrass in making liquid organic fertilizer. Based on the results of the study note that the total macro nutrient levels (N + P2O5 + K2O) Liquid Organic Fertilizer Wastewater and Lemongrass Wastewater is 0.17% with a degree of acidity 4.39. Suboptimal soil nutrient status after incubation for 21 days with different concentration treatments namely 10%, 30% and 50% addition of Liquid Organic Fertilizer tofu waste water and lemongrass experience changes in potassium nutrient status at concentrations of 0%, 10 %, 30% and 50%, while the phosphorus changes at concentrations of 30% and 50%, but not nitrogen.

The Ministry of Agriculture through the Agricultural Quarantine Agency (2019) stated that Robusta coffee has contributed 41% of the country's foreign exchange, with an average export frequency of 102 times per month, and will continue to increase. In connection with the growth in export volume of robusta coffee, coffee farmers need additional substances for the soil in the form of nutrients to be able to meet the soil nutrient needs for coffee from planting to harvest. Organic fertilizer in liquid form is one type of fertilizer that can be an option, in addition to facilitating nutrient absorption. This study aims to determine the response of various liquid organic fertilizers at certain concentrations to the vegetative growth of robusta coffee. The content of C-organic and total Nitogen in the soil which has been given the addition of gamal liquid organic fertilizer and tofu wastewater with the addition of citronella can provide a very significant difference in the vegetative growth of robusta coffee plants at the age of 60 HSP at plant height, and 90 HSP in diameter. stem and number of leaves (strands). Based on the results of laboratory tests carried out, it was also known that the macro and micro nutrient content in the soil with the addition of poc of tofu wastewater which was given citronella had a good content compared to the control and soil conditions with the addition of gamal liquid organic fertilizer.

Tujuan penelitian ini untuk mengetahui pengaruh penggunaan pupuk organik (sapi, ayam, kambing) terhadap pertumbuhan bibit kelapa sawit, mengetahui pengaruh pupuk NPK Pelangi terhadap pertumbuhan bibit kelapa sawit dan mengetahui interaksi pupuk kandang dan pupuk NPK Pelangi terhadap pertumbuhan bibit kelapa sawit di pre nursery. Penelitian dilaksanakan selama 4 bulan, dimulai dari awal bulan maret sampai dengan juli 2022 dan bertempat di kebun percobaan Fakultas Pertanian Universitas Widya Gama Mahakam Samarinda. Metode penelitian ini menggunakan percobaan faktorial 4 x 4 yang terdiri dari 3 ulangan yang disusun dalam Rancangan Acak Kelompok (RAK). Faktor pertama adalah pupuk kandang (K) yang terdiri dari 4 taraf yaitu: K0 = (kontrol), K1 (Sapi) = 250 g/polybag, K2 (Ayam) = 300 g/polybag, K3 (Kambing) = 350 g/polybag. Sedangkan faktor kedua adalah pupuk NPK Pelangi (P) yang terdiri dari 4 taraf yaitu: P0 = (kontrol), P1 = 6,6 g/polybag, P2 = 10 g/polybag, P3 = 13,3 g/polybag. Hasil dari penelitian ini menunjukan bahwa pemberian berbagai jenis pupuk organik berpengaruh nyata terhadap rata-rata diameter batang. Pemberian perlakuan terbaik terdapat pada K3 yaitu pupuk kandang kambing. Selanjutnya pemberian pupuk NPK Pelangi berpengaruh nyata terhadap rata-rata tinggi tanaman, panjang daun, dan panjang akar. Pemberian perlakuan terbaik terdapat pada P2. Kemudian interaksi pemberian pupuk organik kambing K3 dengan dosis 350 g/polybag dan pupuk NPK Pelangi P2 dengan dosis 10 g/polybag sudah mencukupi kebutuhan unsur hara pada bibit kelapa sawit (Elaeis guneensis Jacq.) di pre nursery. Dari hasil penelitian dapat disarankan untuk menggabungkan pupuk kandang kambing dengan dosis 350 g/polybag dan pemberian pupuk NPK Pelangi dengan dosis 10 g/polybag karena memberikan pertumbuhan bibit kelapa sawit yang terbaik di pre nursery terhadap tinggi, diameter batang, panjang daun, dan panjang akar. Perlakuan terbaik yaitu K3P2 Kata kunci : Pre Nursery, Pupuk Kandang, Pupuk NPK Pelang

Abstract This study aims to determine the effect of planting media composition and Trichoderma sp. dosage on the growth of cocoa seedlings (Theobroma cacao L.), as well as their interaction. The research was conducted from March to June 2024 at the Agricultural Research Field, Widya Gama Mahakam University, Samarinda. The design used was a factorial randomized block design (RBD) 3 × 4 with three replications. The first factor was planting media composition: P0 (control), P1 (1:1 cattle manure:topsoil), P2 (1:2 cattle manure:topsoil). The second factor was Trichoderma sp. dosage: T0 (control), T1 (20 g/polybag), T2 (30 g/polybag), T3 (40 g/polybag). Parameters observed were number of leaves, plant height, and stem diameter at 30, 60, and 90 DAP. Results showed that P2 and T2 significantly improved cocoa seedling growth. The best interaction was observed in P2T2 for plant height at 90 DAP. Keywords: Cocoa, growing media, cattle manure, Trichoderma sp.
