Abstract

The research method used was a Randomized Block Design with a 2x4 Factorial Experiment consisting of 3 replications. The first factor is solid organic fertilizer (P) which consists of 2 types, namely: Solid decanter fertilizer (Ps): 5 Kg/Polybag; Manure (Pk): 5 Kg/Polybag. The second factor is gamal leaf liquid organic fertilizer (G) which consists of 4 levels, namely: G0: (control); G1: 10% concentration; G2: 30% concentration and G3: 50% concentration.           The results of the research showed that the treatment of giving gamal leaf liquid organic fertilizer with the lowest concentration, namely G1 (10%), had a significant effect on the fresh fruit weight parameters per plant with the best average weight of fresh fruit per plant being 137.00 g. Providing solid organic fertilizer of the decanter type did not have a significant effect on all parameters. Providing solid organic fertilizer of the chicken manure type had a significant effect on the average height growth of plants at 30 DAP, 60 DAP, 75 DAP, 90 DAP, stem diameter at 15 DAP, 45 DAP, 60 DAP, 90 DAP, and fresh fruit weight per plant.           The interaction of solid organic fertilizer and liquid organic fertilizer with gamal leaves had a significant effect on plant height at 15 DAP, stem diameter at 90 DAP, and fresh fruit weight per plant but had no significant effect on other parameters. The best treatment interaction was PkG1 with a fresh fruit weight of 221.00 gr. Keywords : Solid, Liquid, Fertilizer, Gamal Leaves

Abstract

Suboptimal soil conditions can lead to reduced latex production and quality. One of the main factors influencing latex production is soil fertility, where fertile soil with adequate nutrient content can enhance latex yield. One of the efforts to improve production is through proper fertilization, where the dosage and timing of phosphorus (P) and potassium (K) application must align with the needs of the rubber plant and the condition of the soil. By using appropriate P and K fertilizers, rubber farmers can increase both latex yield and quality. This research was conducted using a factorial experiment with a randomized complete block design (RCBD) and three replications. The first factor was the amount of TSP fertilizer, divided into four categories: P0 = without TSP application per tree, P1 = 175 g per tree, P2 = 200 g per tree, and P3 = 225 g per tree. The second factor was the dose of KCl fertilizer, consisting of four categories: K0 = control, K1 = 200 g per tree, K2 = 250 g per tree, and K3 = 300 g per tree. The findings indicated that TSP fertilizer application had a significant effect on dry rubber content, while KCl doses did not show a significant effect on latex volume, wet latex weight, dry latex weight, or dry rubber content.

Abstract

Urin merupakan salah satu produk buangan yang harus dibuang dari dalam tubuh.  Definisi urin adalah cairan sisa yang diekskresikan oleh ginjal yang kemudian akan dikeluarkan dari dalam tubuh melalui proses urinasi.  Ternyata produk buangan dapat menjadi sesuatu yang bermanfaat bagi kehidupan masyarakat.. Hasil penelitian tentang penggunaan dan pengaruh pupuk organik cair terhadap sosio ekonomi budidaya tanaman dan produktivitas tanah, menunjukan bahwa penggunaan pupuk organik memberikan pengaruh yang lebih baik terhadap pertumbuhan, produksi tanaman dan mengurangi dampak pencemaran lingkungan, tanaman pangan (kedelai, padi, jagung dan kentang) maupun tanaman perkebunan (kelapa sawit, karet, kakao,teh dan tebu)  dibandingkan dengan pupuk anorganik. Sebagai salah satu contoh hasil penelitian dan penerapan pupuk organic di Pati, Lampung, Magetan, Banyumas, pupuk organik terbukti dapat menekan kebutuhan pupuk an-organik urea hingga 100 %.
