Analisis Finansial Pemanfaatan Limbah Tandan Kosong Kelapa Sawit Menjadi Biokar Untuk Media Tanam

Abstract

This paper deal with incineration of the oil palm empty fruit brunches into biochar as carbon fertilizer for planting medium. The inceration process uses carbonized technology at temperature of 400 °F, developed by Ishenny Noor (2015). Application of 22-23% biochar as carbon fertilizer could increase soil carbon content from 0,4-0,7% to 2% / Ha, physical and chemical soil quality, ground water storage, fertilizer activity of soil microorganisms, soil nutrients. Application of biochar on rice plantation yielded 10 tons / ha of black rice / Ha, while application on oil palm plantation yielded oil palm fruit bunch of 20 to 40 kg / bunch. Production of biochar from oil palm empty bunches could give an extra profit for a palm oil processing factory by Rp. 471,926,000 a year (with a capacity of 100 tons/hour of the oil palm empty bunches in 24 hour operation a day) with the ROI of 78%/years, and B/C ratio of 1,71.

Correlation Analysis of Biological and Chemical Properties of SoilIn the Third Generation of Oil Palm Plants at PT. Sinar Pandawa Labuhanbatu

“…The diverse nature of soil is very determining in planning and managing land [12]. Improper land management has resulted in a reduction in microbial populations, biodiversity and reduced soil quality and fertility [10]. Therefore, information regarding the relationship between chemical and biological soil properties is very important for planning sustainable agricultural systems [11].…”

“…The lowest soil respiration was obtained in bamboo fields at 6.229 mg C-CO2 g-1 day-1. This microbial activity is the main factor in increasing the availability of plant nutrients in the soil through the process of decomposition of organic matter and mineralization [10] Correlation between chemical properties and biological properties of soil Correlation tests of soil biological and chemical properties show that microbial, fungal and spore populations and respiration values are most correlated with total soil P content. The correlation value for the total fungal population was highest with total N content of 0.427, while fungi had a negative correlation with pH and C/N ratio.…”

Verification of the Walkley Black Method Test for Determination of Organic Carbon Elements in Palm Oil Empty Fruit Bunch Waste Fertilizer

“…Potensi hasil produksi CPO di Indonesia yang terus mengalami peningkatan berbanding lurus dengan meningkatnya produksi pada tandan buah segar (TBS). Setiap 1 ton TBS yang diolah akan menghasilkan limbah tandan kosong kelapa sawit (TKKS) sebesar 22-23% atau sebanyak 220-230 kg (Lukas et al, 2018). Sehingga dalam kurun waktu 1 jam operasi sebuah pabrik dengan kapasitas pengolahan 100 ton/jam, dapat menghasilkan limbah TKKS sebanyak 22-23 ton (Rahmadi et al, 2014).…”

Potensi Peternakan Sapi Bali Terintegrasi Perkebunan Kelapa Sawit di Kecamatan Tanggetada, Kabupaten Kolaka

“…Tandan Kosong Kelapa Sawit (TKKS) kelapa sawit jumlahnya sangat melimpah. Setiap pengolahan 1 ton TBS (Tandan Buah Segar) akan dihasilkan TKKS sebanyak 22 -23% TKKS [27]. Selain itu, pemanfaatan pelepah sebagai pakan ternak sangat berpotensi tetapi rendahnya protein kasar dan tingginya kandungan serat kasar [28].…”
