Judul: Aplikasi inseminasi buatan terhadap performa reproduksi imago betina ulat sutera liar Attacus atlas
Abstrak: Penelitian ini bertujuan untuk mempelajari pengaruh aplikasi inseminasi buatan terhadap performa reproduksi imago betina ulat sutera liar Attacus atlas. Penelitian menggunakan 28 ekor imago betina yang dibagi dalam dua perlakuan. Perlakuan pertama menggunakan 18 ekor imago yang diinseminasi dan perlakuan kedua menggunakan 10 ekor imago yang tidak diinseminasi. Hasil penelitian menunjukkan rerata bobot badan mati imago yang diinseminasi adalah 4.57±1.95 g, sedangkan imago yang tidak diinseminasi adalah 1.96±1.23 g. Rerata jumlah telur keluar imago yang diinseminasi adalah 51.61±84.02 butir lebih kecil dari imago yang tidak diinseminasi yaitu 235.20±145.71 butir. Rerata jumlah telur tertinggal pada imago yang diinseminasi adalah 207.06±82.92 butir dan 71.40±93.62 butir pada imago yang tidak diinseminasi. Rerata umur imago yang diinseminasi adalah 2.61±2.75 hari, lebih pendek dari imago yang tidak diinseminasi yaitu 9.50±2.42 hari. Aplikasi inseminasi buatan pada imago betina A. atlas menyebabkan peningkatan bobot badan mati dan jumlah telur tertinggal, penurunan jumlah telur yang dioviposisikan per hari, serta pemendekan umur imago.

Judul: Performa reproduksi imago jantan ulat sutera liar Attacus atlas L. (Lepidoptera: Saturniidae)
Abstrak: Attacus atlas L. (Lepidoptera: Saturniidae) is one of Indonesian native insect that has a great potential economy. Fulfillment the demand of material for silk thread still rely that exist in nature, therefore, needs to be done with the use of intensive breeding male imago as effective as possible in mating. The aim of this research was to study the reproduction performance of male imagoes of wild silkworm A. atlas. This research was conducted by allow a male imago mate with three different females. The time of each mating was 6 hours. The parameters observed were the first, second and third ejaculate volume, the number of eggs per imago, egg hatching time and hatchability of eggs. The results showed that the frequency of mating significantly affect the percentage of egg hatchability. The optimum value was achieved at first mating was 53.58 ± 18.26%. The percentage of egg hatchability declined with increasing frequency of mating. The number of eggs per imago and egg hatching time was not influenced by the frequency of mating with the average number of eggs per imago 225.86 ± 34.23 eggs and the average time of hatching eggs was 11.20 ± 3.23 days

Judul: Adsorptivitas arang aktif kayu meranti merah (Shorea sp) terhadap fenol.
Abstrak: Powder or scrap from wood processing has been widely used as adsorbent.This research utilized red meranti wood as an adsorbent for phenol waste. Activation process was carried out with combination of physical and chemical methods. The best condition was obtained with 0.75% NaOH and steam flow for 50 minutes. The adsorption capacity was 7.7−23.6 g/g and the adsorption efficiency was 89−92%. The adsorption mechanism followed Freundlich isotherm with linearity of 99.24%. The quality of the activated carbon was fulfiled the requirement in Indonesia National Standard 06-3730-1995 and was better than comercial activated carbon.
