Judul: Identifikasi keanekaragaman kapang pada imago dan kokon ulat sutera liar Attacus atlas (Lepidoptera: Saturniidae)
Abstrak: Attacus atlas adalah salah satu jenis ngengat di Indonesia yang dikenal dengan nama kupu-kupu gajah. Informasi mengenai keanekaragaman kapang yang terdapat dalam ngengat ini belum banyak diketahui. Tujuan dari penelitian ini adalah untuk memperoleh data keanekaragaman kapang patogen dan non patogen pada fase hidup imago dan kokon ulat sutera liar A. atlas. Kapang diisolasi dari kokon bagian dalam, sedangkan dari imago pada bagian integumen dan saluran reproduksi. Kapang hasil isolasi dikultur pada media potato dextrose agar. Identifikasi kapang hasil isolasi dari kokon dan imago dilakukan dengan pengamalan makroskopis dan mikroskopis. Hasil penelitian menunjukkan bahwa terdapat dua jenis kapang dari kokon A. atlas yaitu F. oxysporum dan A. flavus. Terdapat empat jenis kapang dari imago A. atlas yaitu A. flavus, A, versicolor, A. fumigatus F. dimerum, dan Aspergillus sp. Kapang yang berpotensi merugikan terhadap atlas yaitu F.dimerum, A. fumigatus, A. flavus, dan A. versicolor….

Judul: Eksplorasi Potensi Limbah Imago Ulat Sutera Liar Attacus atlas (Lepidoptera: Saturniidae)
Abstrak: Wild Silkworm Attacus atlas is an Indonesian native germplasm from Aceh to Papua. Cultivation of wild silkworm Attacus atlas has started in line with the high market demand on the caterpillar cocoon. The purpose of this study was to determine the potential of imago waste produced by cultivation of wild silkworm Attacus atlas as a source of alternative feed ingredients and the potency as antimicrobial. Proximate analysis was done to find out nutrition in imago of Attacus atlas, antimicrobial testing using the disk method. The results of the proximate analysis test imago silkworm Attacus atlas shows that the imago contains 75.57% protein, 5.94% fat, 3.80% ash, and 14.64% crude fiber from dry matter. Attacus atlas imago extract is brown, gel, fat as a potential source of animal fat. Antimicrobial test from 96% ethanol extract of imago Attacus atlas with the disk method showed no antibacterial activity against Escherichia coli, Pseudomonas, Streptococcus, and Staphylococcus.

Judul: Studying rate of absorption steam by solutions Lithium Bromide (LiBr) as absorbant in absorption refrigeration
Abstrak: Absorption is the process of absorbing a fluid by another fluid to form a fluid solution. In absorption refrigeration system, LiBr as absorbent filters on components of the absorber will absorb water vapor with lower pressure than the evaporator pressure. The rate of absorption of water vapor is a function of concentration, temperature, humidity and pressure of water vapor. The goal of this research is to see the effect of concentration, temperature and vapor pressure of water at the rate of absorption of water vapor by aqueous absorbent filters (LiBr-H2O) in relation to the cooling system, to determine the equilibrium concentration absorption solution of LiBr-H2O, and to determine the sorption isotherm model. Equilibrium concentration is a function of temperature and humidity. Ce at 40oC and RH 60% was found 37%; at 40oC and RH 70% was 34%; at 40o and RH 80% was 29%; at 45oC and RH 60% was 37.5%; at 45oC and RH 70% was 36%; and at 45oC and RH 80% was 34.5%. The calculation results of Qe using Qe sorption isotherm model on temperature 40oC and 45oC were not too different. The calculation results of the percentage errors between Qe data and model from each of the humidity, obtained the lowest percentage of errors in model Freundlich was 0.4% in RH 60% and 70%; 0.3% in RH 80%.
