Abstrak: One of the efforts to improve the quality of seaweed one of the important marine resources is by drying system that aims to reduce the moisture content. In general, the drying process is carried out in outdoor using a tarp to prevent from sand contaminated . The purpose of this research is to produce seaweed drying instrument with automatic solar dryer and heater system based on microcontroller and to analyze drying seaweed for its level of dried quality. The steps of research are : the design of instrument space, electronic systems, and software design, field test and dried seaweed quality analysis. Electronic system consisting of microcontroller ATmega 32 as the main controller, module DS 1307 as a marker of time, Module SHT 11 as temperature and humidity, data acquisitiq LCD 16x2 as display data temperature, humidity and time recording, SD card for data storage. Field test results obtained temperature range at dryer room is about 32.7 – 64.0 oC and the humidity ranges from 21-85.9% whereas the environmental temperature range about 29.1 – 46.9 oC and humidity range about 37.1-75.6%. The rate of weight loss inside instruments about 0.41-18.33 gr/min whereas conventional drying about 0-15.83 gr/min. Analysis of quality test results for dried seaweed in the dryer show moisture content of gray levels at 18%, 45.61%, fat show the water content 0.59%, 9.20%, protein and carbohydrate levels 26.28%, whereas in conventional drying have at 18% moisture content, ash content 48.90% 0.59%, fats, proteins and carbohydrates, 8.53%, 23.46%, respectively

Judul: Prototype Seaweed Washing Machines Based on Hybrid Technology
Abstrak: Seaweed has a high economic value in terms of its considerable use in various industries of sweets, cosmetics, ice cream, flavourings, bakery, sauce, silk, meat/fishery canning, medicine and iron-rod welding. In 2005,Indonesia has declared that seaweed as one of the leading commodities to be prioritized and revitalized. To produce quality of industrial-scale seaweed has necessary a serious handling, start from harvesting process, uploading, washing, drying, up to manufacturing caraggenan.This study has tried to produce a seaweed washing machine that capable to improve the quality of the seaweed in the washing process. This washing machine is based on hybrid technology that can be operated using energy from pedal-powered and electrical-powered generated from solar panels.The washing machine resemble three-wheeled transport vehicle using pedal-powered for mobility. Activity of seaweed washing process using plastic drum that rotated. There are two different size of plastic drum used in washing machine, the bigger size for static water storage containers and the little one for dynamic (rotation) using pedal-powered or electrical motor.The rolled chain transmission that connected with integrated toothed gear is used to ratate a dynamic drum. The different between pedal-powered and electrical-motor powered lies in process to rotated dynamic drum. Pedal-powered use manpower to rotated dynamic drum but electrical motor powered from electrical that generated from solar panel. Washing machine with pedal-powered similar like pedal powered that contained in bicycle. Solar panel systems which is the source energy for generated electrical motor consists of solar panel itself, controller, battery and DC to AC converter. Overall the machine has works well butt need improvement in terms of manueverability

Judul: Infeksi cacing Ascarid pasa anjing dan kucing, serta hubungannya sebagai zoonosis
Abstrak: Ada tiga cacing Ascarid yang didapatkan pada anjing dan kucing, yaitu Toxocara canis pada anjing, Toxocara cati pada kucing dan Toxascaris leonina pada anjing dan kucing. Ketiganya mempunyai habitat di usus kecil (Soulsby, 1982). Manusia dapat bertindak sebagai induk semang paratenik dari kelompok ini, melalui anjing dan kucing yang menderita sebagai sumber infeksi, terutama anak- anak anjing dan anak-anak kucing (Brown, 1975). Dari kelompok Ascarid ini penyebab utama penyakit pada manusia adalah Toxocara canis (Soulsby, 1982). Penyakit pada manusia yang disebabkan oleh kelompok ini dikenal sebagai penyakit 'Visceral Larva Migrans' (Brown, 1975), Toxocariasis (Beaver, 1966). Penularan pada anjing dan kucing, dapat melalui telur infektif (langsung), induk semang paratenik seperti tikus, kecos, cacing Lanah dan lain-lain (tidak langsung), intrauterin, trans-mammary dan secara fecaloral. Pada manusia, penularan terjadi melalui telur infektif yang tertelan. Gejala klinis yang tampak pada anjing dan kucing yang terinfeksi oleh kelompok ini, adalah anjing kurus, pertumbuhan terhambat, gelisah, batuk, respirasi meningkat, keluar cairan dari hidung, muntah yang kadang kadang bercampur dengan cacing, icterus, diare, sakit pada abdomen, perut buncit dan kadang-kadang timbul gejala konvulsi (Kelly, 1977). Pada manusia tanda klinis yang umum terlihat, yaitu batuk, dispnoe disertai demam dan gejala umum lainnya. Kadang-kadang endopthalmitis, retinitis perifer, papilitis, dan konvulsi. Pemeriksaan darah terlihat eosinofilia, leukositosis, hiperglobulinemia dan pemerik saan yang lain memperlihatkan hepatomegali…dst
