Judul: Kebisingan Pemukirnan Pinggiran Rel Kereta Api: Analisis Preferensi, Persepsi dan Willingness to Accept (Kasus Desa Cilebut Timur KabupaJen Bogor Jawa Barat).
Abstrak: Peningkatan jumlah penduduk Indonesia setiap tahunnya akan mendorong peningkatan aktivitas manusia yang disebabkan oleb sifat "mobile" manusia. Kegiatan pembangunan khususnya di bidang transportasi perlu dilakukan untuk mengimbangi tingginya aktivitas rnanusia, karena akan dimanfaatkan oleh manusia Kemajuan teknologi di bidang Transportasi membutubkan pembangunan fasilitas-fasilitas transportasi, seperti pembangunan stasiun dan rel kereta api. Selain itu, peningkatan jumlah penduduk dan aktivitas manusia juga akan menyebabkan terjadinya peningkatan kebutuhan dan pemanfaatan terbadap Iahan pemukirnan Namun, jumlah ketersediaan Iahan yang bersifat relatif tetap dan terbatas akan mengakibatkan kompetisi dalam penggunaan setiap unit lahan. Pemanfaatan lahan, khususnya sebagai tempat tinggal atau pemukjrnan, juga dipengaruhi oleh tingkat kemiskinan Kemiskinan membuat masyarakat tidak mampu untuk menentukan lingkungan tempat tinggalnya, sehingga makin diabaikannya persyaratan lingkungan pemukirnan, seperti kenyarnanan dan keamanan bagi penduduknya, termasuk persyaratan gangguan kebisingan. Kebisingan/pencemaran, contohnya kebisingan kereta api, akan mempengaruhi kualitas lingkungan di sekitamya. Kebisingan tersebut dapat menimbulkan ekstemalitas negatif terbadap individu-individu masyarakat yang tinggal di sekitar jalur kereta api. Namun pemanfaatan daerah dekat jalur kereta api banyak terjadi, meskipun gangguan kebisingan terdengar hampir setiap saat. Persyaratan daerah pemukjrnan dipandang dari segi gangguan kebisingan, tidak. boleh lebih dari 60 dBA dengan tingkat ideal rnaksimum gangguan sebesar 40 dBA, sedangkan tingkat tekanan pada dekat kereta api adaIah 110 dBA.

Judul: Eksternalitas Negatif Akibat Kebisingan Kereta Api Terhadap Masyarakat di Kelurahan Bekasi Jaya, Bekasi Timur, Kota Bekasi
Abstrak: The increasing of population was related with the high demand through settlement area and transportation infrastructure. As a result, there was competition in the utilization of area where the area characteristic was fixed. It impacts that many resident lived in the settlement did not concerned about the environment factor that could effects toward the convenience and healthy, such as the people who lived nearby the train track. Train activity could create the positive and negative externality. The positive externality were transportation cost savings, easy and fast access. The negative externality were the noise pollution, security, and criminality risk. The research objective were to describe the negative externality caused by the train noise, to determine the willingness of family to receive the compensation funds, to estimate the compensation funds amount that willing to be received by the family as the compensation of train noise, and to determine the factors effects the compensation funds amount received by family. This research used the descriptive analysis, Willingness to Accept (WTA) analysis with Contingent Valuation Method (CVM), and linear regression. The result of research are disturbance due to noise is perceived communication disorder, easy to get shocked, emotional, concentration, increasing of blood pressure, increasing of pulse, disorder on digestion function, majority of respondents willingness to receive the compensation funds as a result of train noise, the alleged value of WTA average respondents is Rp 80 750/month/head of a family, the total value of WTA average is Rp 4 845 000/month and the total value of WTA population is Rp 22 610 000/month, positively variables of WTA model are a long stay, quality of noise, the work of the workers driver, and education and negatively variables are revenues and distance of places live to a source of noise

Judul: Mud Crab’s (Scylla serrata Forskal 1775) Response to Different Decaying Level of Gold Snail (Pomacea canaliculata Lamarck 1822) Bait.
Abstrak: Mud crab is well known as omnivorous-vigorous-voracious-opportunistic-scavenger. These intertidal animals applies mainly chemoreception in their predatory behaviour. It has been commonly assumed that non fresh gold snail bait is better than fresh bait in stimulating the mud crab. This research's aim is to analyze mud crab response to different decaying level of gold snail bait. Their response were observed as time required to touch the bait and pattern and direction of the mud crab in approaching the baits. The different decaying level of gold snail baits were shown on Total Volatile Base Nitrogen (TVBN) as 16.3 mg/100g (0 day); 534.1 mg/100g (3 days); and 887.4 mg/100g (6 days). The research was conducted from July 2009 until February 2011. The TVBN test for gold snail baits were conducted at Laboratory of BBPPHP Jakarta. The experiment was conducted in Pemalang. The result showed that the average period of mud crabs to touch the baits were 52.14 minutes; 61.57 minutes and 52.57 minutes. Anova test concluded no sufficient evidence of significant effect of TVBN content of gold snail bait on mud crab’s feeding behaviour. Movement pattern B, i.e. left and right deviation followed by straight forward movement to the bait, was commonly exhibited by the crabs. Consequences of time period required by the mud crab to approach the bait on fishing operation is discussed.
