Judul: Perubahan Garis Pantai Di Sepanjang Pesisir Pantai Indramayu
Abstrak: The aim of this research is to investigate the characteristics of wave and sediment as well as coastline change in Indramayu. Data for the research consist of Landsat ETM satelite image process and hydro-oceanographic of wave and current. The data were analyzed by using method of energy flux, wind data forecasting, sediment statistics, budget sediment, and processing of the satelite image. Results of the research are (i) maximum wave height ranged from 0.181– 1.179 meter with a period of 1.73 – 3.36 sec, occured on the west season; (ii) sediment of coastal waters was dominated by silt-clay, with a sorting value of very well sorted, skweness very coarse skewed – near semytrical and kurtosis very platikurtik, and maximum transport sediment along the coast 0.13-11.83 kg/day; (iii) tide pattern classified as mixed tide preveling semiurdinal; (iv) current velocity of the waters ranged from 0.012-0.024 m/sec in March and 0.17-0.32 m/sec in July, with a direction of longshore current of 0.14 – 0.34 m/sec; (v) coastline abration occured with an average value of 19.89 m/year.

Judul: Deteksi Perubahan Garis Pantai di Kabupaten Indramayu, Jawa Barat
Abstrak: Pesisir Kabupaten Indramayu memiliki kerentanan pesisir yang tinggi akibat interaksi darat dan laut sehingga mudah mengalami perubahan secara fisik seperti perubahan garis pantai. Deteksi perubahan garis pantai menggunakan teknologi penginderaan jauh merupakan salah satu metode observasi yang dapat dilakukan secara multi temporal. Penelitian ini bertujuan untuk memetakan dan mengetahui perubahan garis pantai di Kabupaten Indramayu, Jawa Barat menggunakan citra Sentinel-2A pada tahun 2016 dan 2022 dengan metode Digital Shoreline Analysis System (DSAS). Hasil dari metode DSAS didapatkan nilai perubahan garis pantai yang memiliki nilai positif dan negatif. Nilai positif berarti pantai mengalami akresi sedangkan nilai negatif pantai mengalami abrasi. Laju abrasi tertinggi terjadi di Desa Paben llir, sementara itu akresi tertinggi terjadi di Desa Krangkeng. Faktor–faktor terjadinya abrasi ialah gelombang, arus, pembukaan lahan seperti tambak sehingga terjadi kemunduran garis pantai. Faktor–faktor terjadinya akresi adalah proses sedimentasi oleh aliran sungai. Kata Kunci: Abrasi, Akresi, DSAS, Garis Pantai., The coast of Indramayu Regency had high coastal vulnerability due to the interaction of land and sea so it easily experiences physical changes such as changes in coastlines. Detection of coastline changes using remote sensing technology is an observation method that can be carried out multi-temporally. This research aims to map and determine coastline changes in Indramayu Regency, West Java using Sentinel-2A imagery in 2016 and 2022 using the Digital Shoreline Analysis System (DSAS) method. The results of the DSAS method show coastline change values with positive and negative values. A positive value means the beach is experiencing accretion while a negative value is that the beach is experiencing abrasion. The highest abrasion rate occurred in Paben Illir Village, meanwhile, the highest accretion occurred in Krangkeng Village. The factors for abrasion were waves, currents, and the conversion of mangroves into ponds resulting in a decline in the coastline. The factors that cause accretion were sedimentation processed by river flows. Keywords: Abrasion, Accretion, DSAS, Shoreline

Judul: The Control And Eradication Of Brucellosis In Cattle From The Standpoint Of Human Health
Abstrak: Brucella abortus occurs both in man and cattle. The organism may thrive wherever cattle are raised by man for breeding purposes. As such, spread to humans can easily be lessened if the disease is properly controlled and/or eradicated in cattle. Control of Brucella abortus in cattle can be under taken by continued vaccination, proper attention to hygiene and the particular care taken in the introduction of only brucellosis-free animals into cattle farms. Vac- cination using the strain 19 or strain 45/20 Brucella abortus vaccine is commonly used, though the former is more popular. Each of these vaccine strains has its own advantages and disadvantages. Eradication of Brucella abortus by the test and slaughter policy can also be carried out after proper vaccination programmes have been initiated and a stage reached where only a very small percentage of positive reactors is found,
