Soedarto, S.H., Tembalang, Semarang, Indonesiae-mail : ristisatya357@gmail.com  ABSTRACT The aim of this research is to study the effect of molasses level increase on physical quality and organoleptic of fattening period goat feed in pellet form. Material used in the research is rice bran, cassava peel, elephant grass, tofu waste product, molasses and premix. Completely randomized design was used in a study with 4 replications and 4 treatments, T0 = pellet ration + 0% molases, T1 = pellet ration + 3% molases, T2 = pellet ration + 5% molases, and T3 = pellet ration + 7% molases. Parameters observed were hardness, durability, color, texture and pellet scent. The results showed that the addition of molasses level had significant effect (P<0,05) on the improvement of physical quality of pellet and the decreasement of pellet organoleptic quality. Pellet with the addition of molasses as much as 3% has the best physical and organoleptic quality. Research conclusions recommended that the addition of molasses up to level 3% can provide good effect for the physical quality and organoleptic pellet. Keywords : Molasses Level, Pellet, Physical Quality, Organoleptic Quality.

Enzim kitinase banyak digunakan dalam bidang medis, makanan, bioteknologi dan lingkungan. Banyaknya kebutuhan enzim kitinase menuntut penyediannya yang murah dan melimpah dengan teknologi produksi yang sederhana. Penelitian ini bertujuan untuk isolasi mikroba kitinolitik dari cairan fermentasi sampah organik, produksi dan uji aktivitas enzim kitinase serta mengetahui karakteristik dari enzim kitinase. Isolasi mikroba telah dilakukan dengan  metode spread plate. Aktivitas kitinase ditentukan secara kualitatif dengan pengukuran indeks kitinolitik dan secara kuantitatif dengan pengukuran absorbansi menggunakan spektrofotometer Uv-Vis pada panjang gelombang 660 nm berdasarkan banyaknya substrat kitin yang dihidrolisis oleh enzim kitinase. Satu dari beberapa isolat yang didapatkan, yaitu isolat A1 menunjukkan aktivitas kitinolitik tertinggi, yaitu sebesar 1,21. Hasil identifikasi mikrobiologi menunjukkan bahwa isolat A1dinyatakan sebagai Pseudomonas pseudomallei. Bakteri ini mampu menghasilkan kitinase secara optimum pada jam ke 18 waktu fermentasi, dengan penambahan molase 0,5% (b/v) dan 1% kitin (b/v) pada media produksinya. Kitinase yang dihasilkan P.  pseudomallei menunjukkan aktivitas optimum pada suhu 50 °C danpH sebesar 6.

The present study investigated the effect of graphene oxide in cellulose acetate-based composite nanofibers on the transdermal delivery of naproxen.

This study aimed to assess the effect of a mixture of garlic powder and Lactobacillus casei (GLC) on intestinal development, hematological parameters, nutrient digestibility, and performance of broilers in the starter phase. One hundred forty 1-day-old broiler chicks were divided into four groups, namely control (not given GLC supplement) and given GLC supplement either 1%, 2%, and 3% of total feed. Chickens were reared for 21 days in an open cage. On the 21st day of the experiment, blood collection, lymphoid organ and digestive organ weight, and performance data were recorded. Accumulative feed intake until day 21 did not differ (P>0.05) among treatment groups. In this study, there were improvements in the height of villi in the jejunum, and the acidity in the duodenum and caecum, due to the increase of short-chain fatty acids (SCFA: acetate and propionate). Protein and crude fiber digestibility in the GLC-given chickens was significantly higher than in the control group ((P≤0.05). GLC supplementation (1%, 2%, and 3% of total feed) significantly increased body weight gain and improved feed conversion ratio (FCR) (P≤0.05). In conclusion, the use of GLC during the starter phase can improve the nutrient digestibility, intestinal health, and performance of broiler chickens.

ABSTRAK. Penelitian untuk mengkajipengaruh penambahan zeolit pada proses pelletizing limbah penetasan, terhadap total Coliform dan Salmonella,telah dilaksanakan di Laboratorium Teknologi Pakan, Fakultas Peternakan dan Pertanian, Universitas Diponegoro. Zeolit dilaporkan mampu mengikat berbagai senyawa kimia, termasuk senyawa beracun, serta mampu mempengaruhi aktivitas mikrobia. Penambahan zeolit dalam pelletizing limbah penetasan diharapkan mampu menurunkan total Coliform dan Salmonella dalam produk pellet, sehingga dapat meningkatkan keamanan produk pellet sebagai bahan pakan alternatif. Dosis penambahan zeolit pada pembuatan pellet yaitu: 0, 2, 4 dan 6%. Data dianalisis dengan analisis ragam dan dilanjutkan dengan uji jarak berganda Duncan. Hasil penelitian menunjukkan penambahan zeolit dalam proses Pelletizing limbah penetasan berpengaruh sangat nyata (P<0,01) terhadap penurunan total Coliform. Peningkatan dosis zeolite dapat menurunkan Total Coliform dan bakteri Salmonella tidak terdekteksi pada pellet limbah penetasan. Dapat disimpulkan bahwa pelletizing limbah penetasan dengan dosis zeolit hingga 6% terbuktimampu menurunkan kandungan Coliform dan Salmonella pada produk pellet.  (Effect administering zeolite in the pelletizing of hatchery waste to contents of coliform and salmonella of the pellet products) ABSTRACT. Experiment to study effect of administering zeolite in the pelletizing hatchery wastes on the total Coliform and Salmonella was done in the Laboratory of Feed Technology, Faculty of Animal Science and Agriculture, University of Diponegoro. Zeolite has been reported have binding capacity on wide range of chemicals, including toxic compounds, and interfere the activity of microbes. Administration zeolite in the pelletizing of hatchery wastes are expected to reduce the total Coliform and Salmonella in the pellet products, therefore improved the safety of the pellet products as an alternative feed ingredients. Doses of zeolite administration in the pelletizing are 0, 2, 4 and 6%. Data were analyzed by analysis of variance (ANOVA) followed by Duncan's multiple range test. The results showed, effect of administering zeolite in the pelletizing hatchery wastes was significant to the total Coliform (P <0.01). Increasing doses of zeolite reduced the Total Coliform and the Salmonella was not detected in the hatchery waste pellets. It could be concluded that pelletizing hatchery waste with a dose of zeolite of up to 6% proven to reduce the content of Coliform and Salmonella in the pellet products.

Dengue virus (DENV) is a significant pathogen emerging worldwide as a cause of infectious disease. Antidengue treatments are urgently required to control the emergence of dengue. DENV is a mosquito-borne disease responsible for acute systemic diseases and serious health conditions. DENVs were distributed in the tropical and sub-tropical areas and transmitted to humans by
