PEMANFAATAN BUNGKIL BIJI KAPUK (Ceiba pentandra) SEBAGAI CAMPURANBRIKET SEKAM PADITHE UTILIZATION OF COTTON SEED MEAL (Ceiba pentandra) AS A MIXTURE OFA RICE HUSK BRIQUETTE

  • PUJI ASRI LESTARI

Abstract

Abstrak. Penelitian ini bertujuan untuk mengetahui perbandingan bungkil biji kapuk dan sekam
padi yang memiliki kadar air, kadar abu, kadar karbon, dan nilai kalor sesuai dengan SNI serta
mengetahui kerapatan, volatile matter, dan laju pembakaran briket. Jenis penelitian yang
digunakan adalah eksperimen dengan desain penelitian The Post Test Only Control Group Design.
Variabel bebas dari penelitian adalah bungkil biji kapuk 100%, 90%, 80%, dan 70%. Variabel
kendalinya adalah suhu karbonisasi 300 oC, jenis perekat dan massa perekat. sedangkan variabel
terikatnya kadar air, abu, karbon, nilai kalor, volatile matter, kerapatan, dan laju pembakaran.
Syarat mutu briket sesuai dengan SNI adalah kadar air ≤8%, kadar abu ≤8%, kadar karbon ≥77%,
dan nilai kalor ≥5000 kal/g. Sedangkan hasil analisis yang didapatkan adalah kadar air yang
diperoleh dari masing-masing briket sudah memenuhi standar mutu briket SNI 01-6235-2000 yaitu
berkisar 4,40-5,03%. Sedangkan kadar abu, karbon dan nilai kalor belum memenuhi SNI 01-6235-
2000. Kadar abu yang didapat berkisar 15,57-23,61%, kadar karbon berkisar 10,73-15,98%, dan
nilai kalor berkisar 2700-4893Kcal/Kg. Sedangkan kadar volatile matter berkisar 60,63-64,05%,
kerapatan yang didapat berkisar 0,6896-0,9926g/cm3, dan laju pembakaran berkisar 0,1025-
0,1618 g/menit.

Abstract.. This research aims to understand the comparison cotton seed meal and husks of the rice
is about level of water, level of ashes, level of carbon, and value of heat engine in accordance with
SNI and knowing the density is, volatile matter, and the rate of burning briquette. The kind of
research that is experiments with research design the post test only control group design. Variable
free of the research are cotton seed meal 100%, 90%, 80% and 70%. Is variable his control
temperature carbonization 300 oC, a kind of adhesive and a mass adhesive. While variable
dependent the water level, ashes carbon, the value of heat engine, volatile matter, the density is,
and the rate of burning. Quality requirements briquette in accordance with SNI is the water level
≤8%, level of ashes ≤8%, level of carbon ≥77%, and value of heat engine ≥5000 cal/g. The
analysis obtained is the water level obtained from each briquettes enough to fulfill briquette quality
standard SNI 01-6235-2000 range 4,40-5,03% , while levels of ashes , the value of carbon and heat
engine SNI 01-6235-2000 have not fulfilled .Levels of ashes obtained range 15,57-23,61% , ranges
10,73-15,98% of carbon , and value of heat engine ranges 2700-4893kcal/Kg. While the level of
volatile matter ranges 60,63-64,05% , the density is obtained range 0,6896-0,9926g/cm3 , and the
rate of burning range 0,1025-0,1618g/minute.
Keywords: Briquettes, Cotton seed meal, rice husk.
