Abstract

This study explored a simple preparation and characterization of the activated carbon and cloth from the palm kernel shell and compared it to the commercial-water-filter-carbon specification. A new pyrolysis chamber that is easily scaled up using the palm kernel shell itself as a heat source was tested. Two different steps were compared: the alkaline activation process performed before or after the carbonation process in the palm-kernel-shell carbon preparation. The palm-kernel-shell activated carbons prepared with the current method fulfilled the standard quality of activated charcoal except for the ash content. The sequencing step of the preparation affected the adsorption capacity. Instead of the reverse sequence, the soaking palm kernel shells in NaOH before the carbonation process lead to a higher adsorption capacity. The carbon particle stability on the cloth surface was affected by both the adhesive concentration and its size. The ammonia adsorption capacity of activated carbon cloth (ACC) was between 1–4 mg ammonia per g stuck carbon. The preparation and the carbon type source on ACC affected the adsorption capacity. The ACC absorbed and lessened the skim latex odor vapor, nearly odorless depending on the ACC area and the volume of odor vapor.

Abstract

Penelitian ini bertujuan untuk menganalisis pengaruh padat tebar yang berbeda terhadap tingkat pertumbuhan dan sintasan udang vaname (Litopenaeus vannamei) pada tambak CV. Markisa Farm. Metode dalam penelitian ini menggunakan metode purposif (Purposive sampling method),  dengan benih post larva (PL) 9 yang ditebar pada wadah luas kolam 1250m2 dengan tingkat padat tebar yakni A1 = 100 ekor/m2, A2 = 150 ekor/m2, dan  A3 = 200 ekor/m2 selama ±3 bulan. Parameter uji utama pada penelitian ini meliputi tingkat pertumbuhan dan tingkat kelangsungan hidup (survival rate) pada udang vaname. Selain itu dilakukan juga pengukuran kualitas air seperti salinitas, pH, ammonia, dan alkali sebagai parameter pendukung. Hasil penelitian menunjukkan pertumbuhan dan kelangsungan hidup tertinggi diperoleh pada A1 dengan padat tebar 100 ekor/m2 menghasilkan bobot rata-rata 24,15 gram/ekor dengan tingkat kelangsungan hidup 94,65% dan terendah pada A3 dengan padat tebar 200 ekor/m2 menghasilkan bobot rata-rata 22,20 gram/ekor dengan tingkat kelangsungan hidup 88,33%. Pemeliharaan udang vaname dengan padat tebar yang tepat akan menghasilkan pertumbuhan dan kelangsungan hidup yang tinggi.
