Judul: Mempelajari Penggunaan Briket Batubara dalam Pengolahan Gula Merah Kelapa (Cocos nucifera L) dan Pembuatan Gula Merah Pasta serta Teknik Pengemasannya
Abstrak: Tujuan penelitian ini adalah : (1) memproduksi gula merah berbentuk pasta dari nira kelapa serta mempelajari sifat fisikokimianya, (2) mempelajari penggunaan briket batubara sebagai bahan bakar dalam pengolahan gula merah kelapa, (3) Mempelajari pengemasan gula merah, gula semut, dan gula merah pasta, serta evaluasi mutunya selama penyimpanan. Penelitian ini terdiri dari dua tahap. Penelitian tahap pertama yaitu pengolahan gula merah dengan bahan bakar kayu dan briket batubara, pengolahan guia semut dan pengolahan gula merah pasta. Sebagai pengawet nira digunakan larutan natrium metabisulfit sebanyak 70 ppm. Penelitian tahap kedua adalah evaluais mutu selama penyimpanan gula merah, gula semut dan gula merah pasta.

Judul: Pemanfaatan limbah Tebu menjadi briket dan biopelet
Abstrak: Sugarcane (Saccharum officinarum) is one of Indonesia's main commodities that provide benefits for life. Sugarcane bagasse and leaves are major waste of sugar mills. Both of waste have not been optimally used. This research conduct a briquette procesing used bagasse and biopellet processing used sugarcane leaves. The aims of this study was to determine concentration of adhesive of briquette and to optimize biopellet process at compression temperature and time. Briquette was made by the addition of tapioca adhesive with concentration of 5, 10 and 15%. Biopellet made used compression temperature and compression time with compression temperature were varied iii from 130 - 270oC and compression time consisted of 8 - 22 minutes. The best briquettes treatment obtained at a concentration of 5% adhesive, with value of 3.87% moisture content, 3.35% ash content, 76.35% volatile matter, 20.29 fixed carbon and heat level 4155 kcal/kg. Sugarcane leaves biopellet has optimal at compression temperature of 250oC for 20 minutes. Compression with these conditions produced moisture content of 3.41%, ash content of 12.19%, compressive strength of 119.22 kgf/cm2 and heat level of 4490 kcal/kg.

Judul: Gambaran Leukosit Domba Ekor Tipis yang Diinfeksi Haemonchus contortus.
Abstrak: The aim of this study was to investigate the effect of Haemonchus contortus infection to white blood cell profile of Javanese thin tail sheep. Twenty males Javanese thin tailed sheep were divided into five groups, namely infected group of 500 L3, 1000 L3, 2000 L3, 4000 L3 and uninfective group as control. The blood and fecal samples were collected from rectum before and three weeks after infection. The blood samples were collected using venoject® from Jugular vein. The fecal samples were collected directly from rectum. The blood samples were examined to determine total of white blood cell (leukocytes) and white blood cell differential, whereas fecal samples to determine egg per gram. The result showed that Haemonchus contortus infections cause an increased total of leukocyte but were not significantly different among of level infection doses (P>0.05). Number of eosinophils were significantly different among uninfected group (P<0.05), but were not significantly different in number of lymphocyte, monocyte, and neutrophil (P>0.05). There where positively correlated significantly between the amount of egg per gram (EPG) and profile of eosinophil (P<0.05), however were negatively correlated significantly between the amount of egg per gram (EPG) and neutrophil’s profile (P<0.05). There where no correlation significantly between the amount of egg per gram (EPG) and profile of white blood cell, lymphocyte, and monocyte (P>0.05).
