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

Abstrak: Development of science and technology today make automatic control have important role. It gives us ease to get performance in dynamic system. Automatic control be able to less routine work that operator always do. Automatic control tools have many kinds. Microcontroller ATMega328P is a kind of automatic control. The function is control and record data then save it. Automatic pitcher irrigation system constructions consist on hardware and software. Hardware consist on water level sensor and soil moisture sensor series, microcontroller, stackable SD card shield, real time clock, relay, battery and solenoid valve. Software is a program for microcontroller that used C/C++ language. Each sensor will be calibrated before use. Daily high water level and soil moisture data was data obtained. The data was obtained each 5 minutes. Data in microcontroller was obtained by record data on memory that was set in microcontroller. Calibration results express that microcontroller capability in monitoring high water level and soil moisture has high accuracy. Determination Coefficient calibration equation from the sensor is 0.955 for high water level sensor and 0.887 for soil moisture sensor. Furthermore, set point for control high water level is 5 cm for bottom margin and 14 cm for top margin.

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
