Judul: Estimasi nilai kompensasi masyarakat akibat eksternalitas negatif aktivitas industri kimia (Kelurahan Gunung Sugih, Kecamatan Ciwandan, Kota Cilegon)
Abstrak: Industri kimia di Kelurahan Gunung Sugih tentunya menghasilkan dampak positif dan negatif. Dampak positif seperti peningkatan lapangan pekerjaan, sedangkan dampak negatif dapat menurunkan tingkat kualitas lingkungan. Studi tentang estimasi nilai kompensasi masyarakat (WTA) akibat eksternalitas negatif aktivitas industri kimia dibutuhkan untuk mencapai aktivitas ekonomi yang berkelanjutan. Tujuan dari penelitian ini adalah untuk mendeskripsikan dampak positif dan negatif akibat aktivitas industri kimia, mengkaji peluang masyarakat menerima dana kompensasi, mengetahui nilai WTA masyarakat, dan mengidentifikasi faktor-faktor yang mempengaruhi nilai WTA masyarakat. Penelitian ini menggunakan analisis deskriptif kualitatif, analisis logistik, penerapan Contingent Valuation Methods (CVM), dan analisis regresi linier berganda. Hasil menunjukkan bahwa manfaat dari keberadaan industri kimia adalah terbentuknya lapangan pekerjaan dan peluang usaha bagi masyarakat. Namun, dampak negatif yang terjadi yakni pencemaran udara, kebisingan suara dan kerugian yang dirasakan masyarakat berupa penurunan tingkat kesehatan dan terganggunya kenyamanan. Nilai rata-rata Willingness to Accept (WTA) responden sebesar Rp42 765.96/bulan/rumahtangga dan total WTA responden sebesar Rp2 010 000/bulan. Faktor-faktor yang berpengaruh nyata terhadap nilai WTA adalah dummy jenis kelamin, pendidikan, pendapatan, dummy udara berdebu, dan dummy persepsi sesak saat bernafas.

Judul: Estimasi Nilai Kerugian Masyarakat Akibat Pencemaran Air Tanah di Sekitar Kawasan Industri (Studi Kasus Industri Keramik di Kelurahan Nanggewer, Kabupaten Bogor)
Abstrak: One of the activities of economy, like an industrial activity may reduce the level of environmental quality. The study of the estimation of both external cost and public compensation (WTA), the effects toward environment caused by industrial activities is needed to achieve sustainable development. The objectives of this study are to identify the negative externality effect of the industry activity, to estimate economic losses and WTA value caused by industrial activities, and to identify the factors that influence WTA value. This paper presents explores the descriptive analysis, valuation of environmental economics, and application of Contingent Valuation Methods (CVM). The result shows that the economic loss of each household per month is IDR 125,716.67 and the average values of household’s WTA per month is IDR 497,674.42. There are seven factors those influence WTA value significantly such as age, gender, income, economic loss caused by replacement cost, education level, the distance between houses and industry area, and economic loss caused by medical cost.

Judul: Light Microscope Study of ConnectiveTissue in The Spleen of Common Rousette Bat (Rousettus amplexicaudatus)
Abstrak: The spleen is the largest lymphoid organ. As a secondary lymphoid organ, in addition to its immune function, the spleen also has functions as blood filtration, storage, and hematopoiesis. The spleen has different morphologies between species that support different physiological functions, one of which is the difference in the structure of the capsule and trabeculae. Capsule and trabeculae of the spleen generally consist of connective tissue and smooth muscle. The thickness of smooth muscle composed together with connective tissue in the capsule and trabecula determines the function of the spleen that is divided spleen into three storage, defense, and intermediate. Bats are the reservoir of various zoonotic diseases. Bats are thought to have unique immune systems compared to other mammals but the characteristics of its immune organs such as the spleen have never been studied before. This study was conducted to examine the characteristics of capsulae and trabecula of the Common Rousette (Rousettus amplexicaudatus).
