Abstrak: Ocean wave is one of the important parameter that affected the dynamic of the coastal. Ocean monitoring that provides real-time data is needed to help better understand of the ocean. The objective of this study are designing and constructing an instrument to measure the wave height. The instrument is designed by using accelerometer sensor and its placed on a buoy to follow the water particle movement on the sea surface. Electronics systems used ATmega32 microcontroller as the main control of this instruments. Data from the sensors stored on the MMC/SD card. Data analysis used MATLAB software by using zero crossing method to get the wave properties. The instruments measured at one fixed point by mooring system. Instrument had undergone fields test in Wakatobi, Southeast Sulawesi and moored at 8 meters depth. Data analysis in 22 hours recording in location showed that the average wave height ̅ was 0.72 meters; the significant wave height (Hsig) was 1.32 meters and the maximum wave height (Hmax) was 2.58 meters.

Abstrak: The aim of this research is to design and construct an instrument to measure beach slope BS-Meter with accelerometer sensor. There were five stages in the design of this instrument, namely: casing design, electronic design, software design, laboratory tests and field trials. The casing is made of aluminum and 1-meter supporting board to make the instrument simple and easy to use. It is assumed, therefore, that within 1-meter there are no changes of the beach slope. An electronic system was built using the Arduino Mega as a microcontroller; while accelerometer sensor and GPS PMB-688 were used to obtain data slope and position, respectively. The data obtained is displayed on the Liquid Cristal Display (LCD) and stored on the SD Card. Laboratory test between BS-Meter and arc angle showed the different between -0.43 up to 0.96 degrees with a value of Root Mean Square Error (RMSE) 0.41. Thus BS-Meters have good accuracy. The Statistics Analysis of the t-test at a 95 percent with confidence interval = 0.05, showed that the value of the angle on the arc angle was not significantly different from the value of BS-Meter. Field test was also performed to compare the results of measuring BS-Meter with a Water pass. The results of field measurements of BS-Meter showed that the Palabuhanratu beach slope ranging from 2.16 to 8.32 degrees, while measurements using waterpass ranging from 2.42 to 11.10 degrees. Error or difference value of measurements between the BS-meter and Water pass is ranging from 0.13 to 3.00 degrees. The determination coefficient calculation (R2) between BS-meter and Water pass ranged from 0.97 to 0.99. Therefore, the BSMeter functions correctly and accurately.

Judul: Trichuriasis pada anjing
Abstrak: Tulisan ini bertujuan menguraikan trichuriasis pada anjing meliputi etiologi, epizootiologi, daur hidup, pato- genesa, gejala klinis, diagnosa, diagnosa banding, progno- sa, dan pengobatan berdasarkan berbagai acuan kepustakaan. Pada tulisan ini lebih ditekankan mengenai segi klinisnya terutama tentang diagnosa, pencegahan, dan pengobatannya. Trichuriasis pada anjing adalah infeksi/radang akut cecum dan colon yang disebabkan oleh parasit cacing Tri- churis vulpis Froelich, 1789. Terdapat di mana-mana di seluruh dunia dan menyerang hampir semua jenis ternak se- perti anjing dan rubah, kucing, rodentia, babi, ruminantia primata, dan manusia. T. vulpis bersifat zoonosis, penu- laran terjadi melalui makanan dan minuman yang terkontami- nasi telur infektif. Daur hidupnya bersifat langsung dan sederhana. Telur yang dikeluarkan cacing betina di luar tubuh induk semang tidak menetas, tetapi mengalami perkembangan larva di da- lam telur. Bila telur infektif termakan, maka di dalam tubuh induk semang akan menetas dan selanjutnya berkembang menjadi cacing dewasa yang hidup di cecum dan colon an- jing. Masa prepaten T. vulpis sangat beragam berkisar an- tara 28-35 hari (Jubb dan Kennedy, 1970) sampai 70-197 ha- ri (Kirk dan Bistner, 1985), dengan rata-rata 10 minggu...dst
