Judul: Tubifex sp Kering - Beku dalam Kemasan Vakum Film Polyvinil Chloride, Polyethylene dan Oriented Polypropylene
Abstrak: Salah satu faktor yang penting dalam usaha budidaya ikan adalah faktor pakan, baik pakan buatan maupun pakan alami. Pakan alami yang cukup potensial untuk dikembangkan antara lain Tubifex sp. Sebagai pakan ikan, Tubifex sp mempunyai kelebihan, antara lain kandungan proteinnya yang cukup tinggi, yaitu 65 % (Bardach et al, 1972) .dan lebih mudah dicerna di dalam usus ikan, yaitu selama 1,5 - 2 jam (Grigyalis, 1967). Mengingat Tubifex sp mudah busuk, karena tubuhnya banyak mengandung air, maka Tubifex sp ini perlu diawetkan. Salah satu metode pengawetan yang dapat diterapkan adalah pengeringan beku (freeze drying). Sedangkan untuk lebih memperpanjang daya awetnya maka produk ini dapat dikemas dengan metode kemas vakum.

Judul: Pengembangan Kemasan Produk Pindang Ikan Tongkol (Euthynnus affinis)
Abstrak: Pemindangan is one of the preservation techniques that combines salting and boiling processes. Until recent days, these method has been applied traditionally without concerning of its hygiene, which causes low quality product. Some improvement was introduced starting from raw material handling, processing and up to packaging, storage and distribution, and produced high quality product according to the SNI 2717.1: 2009 standard. Application of vacuum plastic in packaging technology indicated less damage level of products compared to besek (traditional basket) container. Besek is a bamboo woven that is used as a container for boiling process and as end consumer packaging. It was not able to protect the product then caused shorten it shelf life. Storage in low temperature also implied that besek container was unable to avoid the evaporation process or desiccation occured on the fish surface. Fish appeared to be dried, broken, and even high loss weight. On the storage temperature of 4 C the fungi began to grow after the seventh day. Boiled fish packaged with vacuum plastics was capable to inhibit the evaporation at the surface of the products until 13 days storage. Vacuum plastic packaging also improved the consumer preference since the product deterioration occurred after the fifth week in 4 C of storage temperature and sixth week in -11 C. Development on the processing and packaging technology improved the product quality but consequently also increased the production costs. Based on production cost analysis, traditional salted boiled fish had lower production cost (Rp 3 812 per package), while modern manufactured salted boiled fish increased the production cost to Rp 4 955 per package.

Judul: Utilization of terra/MODIS L1B data for analysis of horizontal wind profile in the troposphere
Abstrak: This study was concerned with horizontal wind derived from data collected with the Moderate-resolution Imaging Spectroradiometer (MODIS) on board the NASA’s Earth Observation System (EOS)-Terra satellite. The aim of this study is to develop a method for the estimation of horizontal wind movement in the troposphere based on Navier-Stokes equation. The method was applied to a calibrated and geolocated Terra/MODIS L1B 1 km data set. The data inputs to estimate surface temperature are retrieved from TIR (Thermal Infrared) bands 31 (10.780 μm to 11.280 μm) and 32 (11.770 μm to 12.270 μm). The obtained surface temperatures were later used to approximate geopotential height on a constant-pressure surface by using the modified Poisson equation. The main assumptions used are the hydrostatic equilibrium, ideal gas law, constant lapse rate and constant acceleration of gravity. Based on the distribution of geopotential height, the pressure gradient force is measured by the gradient of geopotential on an isobaric coordinate to present the horizontal wind profile. For certain topographic areas especially in the mountain ranges, there was a disadvantage of using pressure as a vertical coordinate which lead to inaccuracy. In spite of that, Terra/MODIS L1B data with 1 km spatial resolution can be used to estimate the horizontal wind movement in the troposphere.
