Pengaruh Pemberian Solid (Tandan Kosong Kelapa Sawit) Dan Arang Sekam Padi Terhadap Produksi Tanaman Tomat

Abstract

This study aimed to determine the effect of various types of solid (oil palm empty fruit bunches) and rice husk charcoal on the production of tomato plant (Solanum lycopersicum L). The treatments tested for this study consisted of two factors. The first factor was the provision of solid, i.e. S0 = without solid (control), S1 = 0.50 kg solid polybag-1 , S2 = 0.70 kg solid polybag-1 , and S3: 1 kg solid polybag-1. The second factor was the provision of rice husk charcoal, i.e. P0 = without husk charcoal (control), P1 = 0.2 kg husk charcoal polybag-1 , and P2 = 0.4 kg husk charcoal polybag-1. Each polybag contained 5 kg of air-dried soil. The results of this study indicated that the provision of solid and rice husk charcoal against tomato plant production had no significant effect on stem diamater, total number of fruits per plant, and total weight of fruits per plant. However, the treatment interaction of 1 kg solid polybag-1 and 0.2 kg husk charcoal polybag-1 increased stem diameter, total number of fruits per plant, and total weight of fruits per plant.

Provision of Urea Fertilizer and Organic Fertilizer of Rice Husk Charcoal on the Growth of Oil Palm Seeds

“…The results from Table 1 can be seen that the effect of organic fertilizer doses of rice husk charcoal and urea fertilizer on oil palm seedlings on plant height, namely Urea Fertilizer (kg/ha) U3 (300 kg/ha the highest was 77.78 cm2 while the lowest treatment was T0 ( 0 tons/ha) and U3 (300 kg/ha) of 52.19 cm2 while T2 (20 tons/ha) Organic Fertilizer Rice Husk Ash , this shows that optimal organic fertilizer levels can increase soil fertility by improving soil physical, chemical and biological properties. so that the plant response at a dose of 1.5 kg of compost showed more optimal leaf growth than other doses.This is in line with the opinion of Fadhillah and Harahap (2020), that optimal levels of soil organic matter will improve the physical, chemical and biological properties of the soil in support plants.…”

Monitoring Tingkat Ph dan Kandungan NPK pada Proses Composting Tandan Kosong Kelapa Sawit

“…Kegagalan penanganan limbah utama kelapa sawit dengan cara merombaknya menjadi kompos secara alami terletak cara menata limbah di tempat yang tidak nyaman, tidak dilakukan pengukuran tingkat pH serta keterbatasan alat untuk memantau kandungan unsur hara secara berkala di dalam tumpukan kompos tankos (Herman et al, 2021). Sebagaian besar pengelola tandan kosong kelapa sawit belum memanfaatkan teknologi pengolahan sampah (Leksi et al, 2019) yang memudahkan pengukuran dan monitoring parameter-parameter yang menjadi penentu kematangan kompos (Fadhillah & Harahap, 2020). Hal ini perlu dilakukan karena limbah tankos merupakan sisah dari hasil proses produksi kelapa sawit tersedia dalam jumlah banyak(Saputra & Stevanus, 2019) dan terus meningkat dari waktu ke waktu.…”

Aplikasi Seedballs untuk Pertumbuhan Benih Nangka (Artocarpus heterophyllus), Bisbul (Diospyros blancoi), dan Merbau (Intsia bijuga)

“…Penambahan arang sekam dan limbah kelapa sawit mampu mempercepat laju perkecambahan benih merbau. Hal tersebut selaras dengan hasil penelitian Fadhillah & Harahap (2020) bahwa penambahan arang sekam dan tandan kosong kelapa sawit mampu meningkatkan pertumbuhan tomat.…”
