Judul: Sebaran Spasial dan Temporal Genangan Banjir Rob di Kota Pekalongan menggunakan Citra Satelit Landsat 8 OLI
Abstrak: Banjir rob merupakan suatu fenomena yang disebabkan oleh pasang surut yang menggenang daratan dengan ketinggian elevasi lebih rendah dari perairan. Salah satu daerah yang terdampak fenomena ini adalah Kota Pekalongan. Teknologi penginderaan jauh secara efektif dapat digunakan untuk mengetahui sebaran spasial dan temporal genangan banjir rob Kota Pekalongan dari tahun 2014 hingga 2018. Sebaran banjir rob didapatkan dari ekstraksi data daratan dan lautan yang disesuaikan dengan data ketinggian elevasi muka tanah Kota Pekalongan dan faktor penyebabnya. Hasil analisis menujukan bahwa setiap tahun terjadi perubahan luasan genangan banjir rob. Pada tahun 2014 seluas 957.47 hektar atau 20.63 % dari total luas Kota Pekalongan dengan 13 desa terdampak, tahun 2016 seluas 660.63 ha atau 14.23 % dari total luas Kota Pekalongan dengan 10 desa terdampak, dan tahun 2018 seluas 960.96 ha atau 20.70 % dari total luas Kota Pekalongan dengan 13 desa terdampak. Hal ini desebabkan karena pengaruh faktor pasang surut, angin, curah hujan, serta penurunan muka tanah. Tinggi genangan dan durasi genangan setiap tempat berbeda, tergantung dari ketinggian elevasi tanah, serta jarak ke laut dan sungai.

Judul: Analisis daerah genangan banjir rob (pasang) di pesisir utara Jakarta menggunakan data citra satelit SPOT dan ALOS
Abstrak: Most of the land area of the northern coast of Jakarta is a result of reclamation of mangrove forest area, thus changing the shoreline and mangrove buffer function vanish. Effect of shoreline phenomena such as tidal flood rob), it makes some parts of the region including the northern coast of Jakarta which has a coastline along the 32 km flood affected by tidal flood (rob). Floods tidal (rob) occur when sea water runoff to the mainland every time the high tides that inundate the region is lower than the average sea level. Effect of population makes land a solid building, make change in land cover wet into dry land by the construction of wet areas resulting from land use changes. Through the results of land use change, coastlines changes and inundation prediction using data of sea level rise can be explained tidal flood (rob). SPOT (2003) and ALOS (2008) satellite imagery can explain land cover changes over the past five years, and the value of sea level rise per year to predict inundation within the next ten years. Because of changes in coastal land, coastline changes that lead to the addition of soil (accretion) and a decrease in surface (abrasion). Addition of soil (accretion) explains the more advanced the shoreline that have an impact on the pool of sea water at high tide when the maximum occurs. Based on field surveys carried out, explaining that changes in the research area of coastal land cause tidal flood (rob). Inundation predictions using DEM-GDEM data 30 m, the level of the value of the coastline and the sea rose to explain the occurrence of inundation in coastal areas north of Jakarta in 2019. The results obtained from several methods to explain the inundation occurred in the same area, so that could explain the relevance of changes in land and sea level rise which resulted in tidal flood (rob) event.

Judul: Kandungan Kolesterol dan Vitamin A Ayam Arab yang Diberi Jamu Ternak Melalui Air Minum
Abstrak: Egg as one source of protein needed by the body contains high amount of essential amino acids, however in reality there is a constraint factor in consuming the eggs which is the high level cholesterol in an egg. Nowadays the cholesterol content of eggs is feared by most of the public in relation to its effect. Excess cholesterol can cause health problems, but on the other hand the yolks contain vitamin A which is good for the body. This research was aimed to study the cholesterol and vitamin A content of Arab chicken egg yolks with addition of herbs through drinking water it is expected to reduce the cholesterol level and increase the amount of vitamin A in egg yolks. This experiment was conducted in poultry house in block C of Animal Science Faculty, Bogor Agricultural Institute, it lasted from June to August 2011. Chicken used in this study was 48 arab hens by age 19 weeks. Research procedures include the preparation of cages and equipment, maintenance and provisions of herbal medicine. The design used in this study was a completely randomized design (CRD). The content of cholesterol during 5 weeks of herbal medicine with level of 5 ml per head and 10 ml per head was 535.28 mg/100 g up to 563.51 mg/ 100 g. The addition of herbal medicine for 3 consecutive days (per week) are mixed in hens drinking. The level differences does not affect the content of cholesterol in egg yolk, but the existence of different herbal medicine addition level provides different amount of vitamin A. The content of vitamin A in egg yolks for a treatment P0 (without herbs) amounted to 596.787 μg/ 100 g, P1 (herbs 5 ml/head/day) : 700.034 μg/ 100 g and P2 (10 ml/head/day) : 800.962 μg/ 100 g.
