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 Virus Parainfluenza Pada Anjing
Abstrak: Virus parainfluenza anjing termasuk famili Paramyxoviridae, berbentuk pleomorf dengan ukuran bervariasi (bergaris tengah antara 100-500 nm), berpembungkus peka ether, berisi genom RNA dan secara serologis mempunyai kesamaan dengan virus SV-5 kera; dikenak sebagai salah satu kausa penting dari sindrom "kennel cough". Infeksinya dapat mengenai anjing semua umur yang belum pernah terinfeksi atau mendapatkan vaksinasi mengakibatkan gejala klinis ringan yang terbatas pada traktus respirasi atu infeksi yang secara klinis tidak memperlihatkan gejala nyata. Gejala klinis yang nampak setelah masa inkubasi (1-5 hari) terlewati berupa batuk yang tidak berat selama beberapa hari, berbagai tingkat tonsilitis dan pharyngitis dan kadang-kadang ditemukan kenaikan temperatur rektal antara 1-2 derajat C dari temperatur normal rat-rata. Anjing terinfeksi mengandung virus pada traktus respirasi bagian atas dan bawah serta limfonoduli sampai hari ke 9 setelah infeksi. Penyebaran virus antar anjing terjadi secara aerogen.
