Abstract

Kakao (Theobroma cacao L) merupakan buah yang telah lama berkembang luas di Indonesia. Limbah dari buah kakao berupa kulit buah kakao basah yang belum maksimal dalam pemanfaatannya, dengan demikian kulit kakao akan menghasilkan limbah dengan volume yang besar. Untuk itu perlu dilakukan pemanfaatan limbah kulit buah kakao sehingga akan meningkatkan nilai ekonomis dengan menjadikannya pupuk organik. Kulit kakao memiliki kandungan pH 4,9 , C-organik 30,12 %, N total 0,96%, C/N 31 dan bahan organik 52,11 % sehingga berpotensi dijadikan pupuk organik. Penelitian ini bertujuan untuk mengetahui pengaruh penambahan variasi bioaktivator dan dosis kotoran kambing. Rancangan percobaan penelitian ini adalah Rancangan Acak Kelompok (RAK) dengan 2 faktor yaitu bioaktivator (Bregadium, Petrofast, Decoprima) dan kotoran kambing ( 0,5 kg; 1 kg dan 1,5 kg). Hasil penelitian menunjukkan limbah kulit kakao dapat dijadikan pupuk organik setelah pengomposan 32 hari, penambahan bioaktivator dan kotoran kambing berpengaruh nyata terhadap nilai C-organik dan reduksi pupuk organik. Mutu terbaik dari penelitian ini pada perlakuan penambahan bioaktivator Bregadium : 0,5 kg dengan C-organik 23.83 , N-total 2.08 dan rasio C/N 11.60. Jika dibandingkan nilai C-organik dan N-total sudah memenuhi standar Standar Teknis Pupuk Organik.

English Abstract

Cocoa (Theobroma cacao L) is a fruit that has long been widespread in Indonesia. Waste of fruit cocoa pod husks wet form is not maximized in their utilization, thus cocoa skin will produce large volumes of waste. It is necessary for the utilization of waste pod husks that will enhance the economic value by making organic fertilizer. Cocoa skin contains 4.9 pH, organic C 30.12%, 0.96% total N, C / N of 31 and 52.11% of organic materials that could potentially be used as organic fertilizer. This study aimed to determine the effect of variations in bio-activator and a dose of goat manure. The experimental design of this study is a randomized block design (RBD) with two factors, bio-activator (Bregadium, Petrofast, Decoprima) and goat manure (0.5 kg, 1 kg and 1.5 kg). The results showed cocoa shell waste can be used as an organic fertilizer after composting 32 days, the addition of goat manure bio-activator and significantly affect the value of C-organic and reduction organic fertilizers. Best qualitiy of this study on the treatment of bio-activator addition Bregadium: 0.5 kg with organic C 23.83 , N-total of 2:08 and C / N ratio 11.60. When compared to the value of organic C and N-total already meet the standards of the Technical Standards Organic Fertilizer.
