    Gluten-free products are needed by people with gluten allergy such as celiac disease and autism. The consumption of gluten-free products rises annually and, therefore, there is potential in the development of gluten-free products. Most of the non-gluten pasta products (NGP) contain a low amount of protein. In this study, NGP prepared from modified cassava flour (mocaf) (40%), rice flour (35%), and maize flour (25%), was supplemented with tempeh flour as a source of protein. In this research, NGP was prepared by extrusion. The cooked dough was extruded using a single screw extruder (screw diameter, 60 mm, locally manufactured by the Research Centre for Appropriate Technology-Indonesian Institute of Sciences, Subang, West Java Indonesia). The procedure of making NGP involved mixing all ingredients, steaming, extrusion, tempering, drying, and packaging. The effect of tempeh flour supplementation (0%, 2.5%, 5%, 7.5%, 10%, 12.5%, and 15% (w/w)) on the properties of NGP product was evaluated. The parameters of NGP that were evaluated included chemical properties, texture profile, elongation break, cooking properties, crystallinity structure, and morphological properties. The chemical properties included proximate and mineral content (iron (Fe) and zinc (Zn)) analysis. Results showed that adding tempeh flour significantly increased the protein, fat, fibre, iron, and zinc contents of NGP. The NGP had a moisture content of approximately 10%–12%. The higher tempeh flour addition resulted in the higher protein, lipid, Fe, and Zn contents of NGP. The highest protein and minerals (Fe and Zn) were obtained by 15% tempeh flour addition. Adding a higher amount of tempeh flour induced the higher percentage of V-type crystalline structure of amylose–lipid complex. Higher supplementation of tempeh flour resulted in higher cooking loss and decreased adhesiveness, springiness, and cohesiveness of the NGP product. The range of cooking time of NGP was between 5 min 25 sec and 6 min 50 sec. The supplementation of tempeh flour in the NGP reduced the cooking time. Observation of the morphological properties showed that starch of NGP ingredients had been fully gelatinized during the extrusion process as indicated by absence of intact starch granules.  Based on the results, it is suggested to supplement NGP with tempeh flour up to 10% (w/w) to get the nutritional advantage of tempeh without depressing its textural and cooking qualities

    Edible film (lembaran tipis dapat dimakan) berbasis karagenan-lilin lebah telah dibuat dengan menggunakan dua jenis plasticizer (bahan pemlastis) yaitu gliserol dan gula. Gliserol pada konsentrasi tetap 1% dikombinasikan dengan gula (fruktosa, glukosa dan sukrosa) masing-masing pada tiga level konsentrasi yaitu 0,5%, 1% dan 1,5% b/vt. Edible film mempunyai kadar air, ketebalan, kuat tarik, elongasi dan kecepatan transmisi uap air masing-masing sebesar 13,69-14,91%, 0,059-0,102 mm, 12,62-32,40 MPa, 13,34-43,57% dan 17,65-25,38 g/m2/24 jam. Kenaikan konsentrasi plasticizer menghasilkan kenaikan kadar air, ketebalan, elongasi dan kecepatan transmisi uap air namun menurunkan kuat tariknya. Semua edible film menunjukkan sifat warna yang baik dengan lightness antara 84,45-85,61 sedangkan edible film dengan plasticizer gliserol-sukrosa memperlihatkan lightness paling rendah. Hasil scanning electron microscopy menunjukkan bahwa edible film yang diberi perlakuan Plasticizer gliserol-fruktosa dan gliserol-glukosa memiliki permukaan yang lebih homogen dan halus daripada edible film kontrol dan edible film dengan plasticizer gliserol-sukrosa

    Leptospirosis becomes health problem in Indonesia. Until April 2014, cases of leptospirosis transmitted by rats were reported in Boyolali with case fatality rate (CFR) 83.3%. Leptospira genus consists of various serovars and genetic types living in different environment. Classification of Leptospira species based on rpoB gene could be used as this gene has high level of polymorphism. This study aimed to identify Leptospira serovars in rat population using kinship analysis based on rpoB gene polymorphism and to describe spatial distribution of rats with Leptospira positive in Boyolali District. A cross sectional study was conducted on April 2014 at Sindon Village in Ngemplak Subdistrict and Jeron Village in Nogosari Subdistrict, Boyolali District. Polymerase Chain Reaction test was performed on 104 rat kidney samples from the two locations of study. Spatial analysis was conducted to map distribution of rats with Leptospira positive. There were six positive rpoB gene samples in Rattus tanezumi, Rattus argentiventer and Suncus murinus. Five of six positive samples showed the closest genetic kinship to Leptospira borgpetersenii serovar Sejroe based on rpoB gene. One isolate did not have a close genetic kinship to any serovar included in the cluster. Spatial analysis based on home range buffer zone showed that rats with Leptospira positive were found in 30 meter and 150 meter from leptospirosis patients

    Malaria and Dengue Haemorrhagic Fever (DHF) are two major tropical diseases in East Java. The pathogens of these diseases are transmitted to human hosts via haematophagy by vector mosquitoes. Anopheles spp. specifically transmits Plasmodium parasites which cause Malaria, while Aedes spp. transmits Dengue viruses that cause DHF. Bangsring, Banyuwangi is one of the endemic areas of Malaria, while Jember is one of endemic areas of DHF. Two species of Malaria vectors i.e Anopheles vagus and Anopheles sundaicus have been found from several samplings which were conducted in Bangsring region. This mosquitoes have been previously identified as a major vector for malaria. Aedes aegypti and Aedes albopictus, which were major vectors for DHF, have been easily found in Jember during our sampling for any season of the year. This research wanted to differentiate the morphological characteristic of those vectors for malaria and Dengue. Adult mosquitoes can be distinguished from one another by characterizing their morphological features. Palpi, wings, and legs characteristics are commonly used as determination keys in Anopheles sp., while thoraxes and legs characteristics are used as identification keys in Aedes sp. Morphological identification is considered as the basic necessity in understanding and determining bionomic of mosquito vector. This is very important in developing effective and efficient mosquito vector control strategies, which is also an important step to prevent the death risks associated with Malaria and DHF cases
