Penelitian berjudul “Pengaruh Penambahan Buah Maja 
(Aegle marmelos) pada Dekomposer terhadap Kinetika Suhu dan Rendemen Kompos Feses 
Sapi Potong”. Penelitian dilaksanakan pada tanggal 28 November 2020 hingga 09 Januari 
2021 di PT.Catur Mitra Taruma Bogor, Jawa Barat. Tujuan dari penelitian adalah mengkaji
kinetika suhu dan rendemen kompos berbahan baku feses sapi potong dengan 
penambahan buah maja dengan dosis berbeda pada dekomposer.
Bahan baku yang digunakan yaitu feses sapi potong dalam bentuk basah 9000 kg, 
buah maja (Aegle marmelos) segar 540 gr, limbah rebung dalam 3,6 kg, molasses 1,8 L, air 
16,2 L, dan tepung beras 18 sdm. Rancangan penelitian yang digunakan adalah Rancangan 
Acak Lengkap (RAL) yang terdiri dari 3 perlakuan dengan 6 kali, sehingga diperoleh 18 unit 
percobaan. Perlakuan yang diberikan adalah penambahan buah maja (Aegle marmelos)
yaitu A0 (kontrol), A1 (0,03%), dan A2 (0,06%).Variabel yang diukur adalah kinetika suhu 
pada proses dekomposisi dan rendemen kompos. Pengukuran kinetika suhu dilakukan 
setiap hari pukul 08.00 dan 15.00 dan dengan pengamatan transisi pada hari ke-1, 4, 8, 12, 
16, 20, 24, dan 28, sedangkan pengukuran rendemen dilakukan pada akhir pembuatan 
kompos. Data dianalisis menggunakan Repeated Measures ANOVA (RMA) untuk kinetika 
sushu dan ANOVA (Analysis of Variance) untuk rendemen. 
Hasil analisis variansi terdapat interaksi yang nyata (P<0,05) antara perlakuan dan 
waktu pengamatan pada kinetika suhu. Suhu optimum dicapai pada pengamatan hari ke12 untuk perlakuan A0 (59.88oC), dan pengamatan hari ke-16 pada perlakuan A1 (60,63oC) 
dan perlakuan A2 (62,28oC). Suhu akhir yang dicapai pada hari ke-28 yaitu suhu A0 
(52,43oC), A1 (55,97oC), dan A2 (59,95oC). Hasil analisis variansi. Rendemen tidak terdapat 
perbedaan yang nyata pada ketiga perlakuan. rendemen yang dihasilkan yaitu 65,995 (A0); 
64,36% (A1); dan 66,79% (A2). Kompos yang menggunakan decomposer dengan 
penambahan 0,06% buah maja (perlakuan A2) menghasilkan kinetika suhu terbaik, namun 
rendemen yang dihasilkan relatife sama antar perlakuan.

. The research entitled "The Effect of Addition of Maja Fruit 
(Aegle marmelos) to the Decomposer on Temperature Kinetics and Yield of Beef Cattle 
Fecal Composition". The research was conducted on November 28, 2020 to January 9, 2021 
at PT. Catur Mitra Taruma Bogor, West Java. The purpose of this study was to determine 
the temperature kinetics and the percentage of compost yield made from beef cattle feces 
with the addition of maja fruit with different doses to the decomposer. 
The raw materials used were 9000 kg of beef feces in wet form, 540 grams of fresh 
fruit of maja (Aegle marmelos), 3.6 kg of fresh bamboo shoots waste, 1.8 L of molasses, 
16.2 L of water, and flour. rice 18 tbsp. The research design used was a completely 
randomized design (CRD) consisting of 3 treatments with 6 repetitions, in order to obtain 
18 experimental units. The treatments given were the addition of maja fruit (Aegle 
marmelos), namely A0 (control), A1 (0.03%), and A2 (0.06%). The measured variables were 
temperature kinetics in the decomposition process and the percentage of compost yield. 
Temperature kinetics measurements were carried out every day at 08.00 and 15.00 and 
with transitional observations on days 1, 4, 8, 12, 16, 20, 24, and 28, while the yield 
percentage measurement was carried out at the end of composting. Data were analyzed 
using Repeated Measures ANOVA (RMA) for temperature kinetics and ANOVA (Analysis of 
Variance) for percentage of rendemen. 
The results of the analysis of variance showed a significant interaction (P <0.05) 
between treatment and time of observation on temperature kinetics. The optimum 
temperature was achieved on the 12th day of treatment for treatment A0 (59.88oC), and 
the observation on the 16th day on treatment A1 (60.63oC) and treatment A2 (62.28oC). 
The final temperature reached on the 28th day was A0 (52.43oC), A1 (55.97
oC), and A2 
(59.95oC). The results of the analysis of the percentage of yield variance showed no 
significant differences in the three treatments. The yield percentage produced was 65.995 
(A0); 64.36% (A1); and 66.79% (A2). The results of orthogonal polynomials showed 
significant differences that varied in temperature kinetics in the three treatments. Compost 
using decomposer with the addition of 0.06% Maja fruit (A2 treatment) produces the best 
temperature kinetics, but the yield produced is relatively the same between treatments.
