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: Shoreline Changes in the Coastal of Sungai  Limau Subdistrict, Padang Pariaman Regency, West Sumatra Province
Abstrak: Pesisir merupakan wilayah peralihan antara darat dan laut sehingga sangat potensial sebagai lokasi pembangunan. Pembangunan kawasan pesisir yang semakin pesat menyebabkan adanya perubahan tata guna lahan. Penelitian ini dilakukan untuk mendeteksi perubahan garis pantai Kecamatan Sungai Limau Kabupaten Padang Pariaman, Sumatra Barat tahun 2016-2020 menggunakan citra satelit sentinel. Laju perubahan garis pantai dihitung menggunakan metode Digital Shoreline Analysis System (DSAS). Parameter yang dibutuhkan dalam metode DSAS yaitu baseline, shoreline, dan transect. Perubahan garis pantai pada transek dihitung dengan perhitungan End Point Rate (EPR) dan Net Shorline Movement (NSM). Abrasi terjadi pada semua zona yang meliputi Desa Pilubang, Desa Kuranji Hilir, Desa Koto Tinggi dan Desa Guguak. Desa Pilubang mengalami abrasi terbesar dengan perubahan garis pantai 114,59 meter. Desa Kuranji Hilir mengalami abrasi sebesar 94,60 meter, Desa Koto Tinggi mengalami abrasi sebesar 86,93 meter dan Desa Guguak mengalmi perubahan garis pantai berupa abrasi sebesar 78,72 meter. Perubahan garis pantai yang terjadi di pesisir Pantai Sungai Limau dipengaruhi oleh arus (0,12 – 0,25 m/s), angin (5 – 2 m/s), gelombang (0,3 – 0,93 meter) dan pasang surut (-0,6 – 0,8 meter). Arus yang bergerak menyusuri pantai yang terbentuk akibat angin dan gelombang yang ada di pesisir Kecamatan Sungai Limau mengakibatkan terjadinya abrasi., The coast is a transitional area between land and sea so it is very potential as a location for construction. The rapid development of coastal areas causes changes in land use. This research was conducted to detect changes in the coastline of Sungai Limau Subdistrict, Padang Pariaman Regency, West Sumatra Province from 2016- 2020 using sentinel satellite imagery. The rate of shoreline change was calculated using the Digital Shoreline Analysis System (DSAS) method. The parameters needed in the DSAS method are baseline, shoreline, and transect. The shoreline change on the transect is calculated by the End Point Rate (EPR) and Net Shoreline Movement (NSM) formulas. Abrasion occurred in all zones which include Pilubang Village, Kuranji Hilir Village, Koto Tinggi Village, and Guguak Village. Pilubang Village experienced the biggest abrasion with a coastline change of 114.59 meters. Kuranji Hilir Village experienced an abrasion of 94.60 meters, Koto Tinggi Village experienced an abrasion of 86.93 meters and Guguak Village experienced a change in the coastline in the form of abrasion of 78.72 meters. Coastline changes that occur on the coast of Sungai Limau are influenced by currents (0.12 – 0.25 m/s), wind (5 – 2 m/s), waves (0.3 – 1.42 meters) and tides (-0.6 – 0.8 meters). Currents that move along the coast formed by wind and waves on the coast of Sungai Limau District cause abrasion.

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,
