Judul: Kajian Implementasi Produksi Bersih di Industri Penyamakan Kulit (Kasus Desa Cibuluh, Kecamatan Bogor Utara)
Abstrak: Leather tanning industries are industries that process animal skin to produce finish leather product by using many stages of process. Every stage of the process will generate a large amount of wastes, either liquid or solid wastes. If the waste is not treated properly, it will cause environmental pollution. Implementation of cleaner production strategy can be used to solve this problem. This research studies the potentials of cleaner production application and alternative of cleaner production strategy in order to develop environmental friendly tanning industry in Cibuluh. The method used was process identification, waste sourch identification, and cleaner production analysis strategy. The cleaner production alternatives which are potential to be applied are design of installation wastewater to IPAL with pipe from molen machine, reuse wastewater from pre soaking process for the next batch, separation wastewater from hair and flesh, processing of fleshing waste for fat, and recycle chromium from tanning wastewater. Based on the priority alternative, three options were selected, namely recycle chromium from tanning wastewater, separation wastewater from hair and flesh, and reuse wastewater from pre soaking process for the next batch. The total investment of these option is Rp 2,059,500,- with pay back period (PBP) of 0.17 month. The Analitycal Hierarchy Process (AHP) analysis result shows that industrial policy is the most important factor to minimize waste product of tanning industry. The priority of cleaner production program from AHP analysis is recycle chromium from tanning wastewater which is consistent to that resulted from field study.

Abstrak: Tanning industry processes rawhide to produce leather in which this process results in by products as well as liquid and solid wastes. Cleaner production could be implemented as a preventive method that can reduce waste formation. Logistic chain related to this tanning process are breeder, slaughter house, rawhide trader, and the tanning industry. This research aimed to identify the input, output and generated waste, the cleaner production options that can be applied to the logistic chain, and to determine the role of society on the implementation of cleaner production. The methods used in this study were quick scan of logistic chains and Analytical Hierarchy Process (AHP). The best cleaner production option in raw material preparation is socialization to the butcher and farmers. While that in the main process are arranging stage of fleshing process to be conducted before soaking process, reuse of soaking and chrome waste, converting powder and feather waste to be construction materials, applying Occupational Health and Safety (OHS) management and setting screen above molen machine. AHP result showed that industry and the environment is the most important actor and factor respectively. The best selected option of cleaner production is recycling chrome waste in tanning process. The role of community in the implementation of cleaner production includes complying the OHS procedure for workers and warning the company to comply the environment.

Judul: Karakteristik Anatomi Skelet Kepala Buaya senyulong (Tomistoma schlegelii).
Abstrak: Buaya sepit atau senyulong (Tomistoma schlegelii) merupakan jenis buaya asli Indonesia yang berhabitat di sungai-sungai Sumatera, Kalimantan, dan juga pedalaman Sulawesi. Salah satu ciri khas buaya senyulong adalah bentuk moncong yang runcing dan sempit, namun hingga saat ini informasi mengenai struktur skelet kepala buaya senyulong sangat terbatas. Penelitian ini bertujuan untuk mempelajari karakteristik anatomi skelet kepala buaya senyulong yang dikatikan dengan fungsi dan perilakunya. Penelitian dilakukan secara eksploratif dengan melakukan pengamatan, pencatatan, dan pengambilan gambar dari skelet kepala buaya senyulong. Skelet kepala berukuran panjang 70 cm, lebar 29 cm, dan tingggi 17 cm dengan permukaan kasar pada os nasale, os frontale, os maxilla, os mandibula, os lacrimale, os jugale. Jumlah gigi pada buaya ini sebanyak 78 buah, terdiri dari 4 buah gigi premaxila, 16 buah gigi maxila, dan 19 buah gigi mandibula. Pada regio orbitalis ditemukan dua pasang fenestrae temporales yang berkembang baik. Fenestra supratemporale merupakan lubang oval yang membentang di sepanjang os parietale. Fenestra infratemporale berbentuk segitiga dan dibatasi oleh os squamosum, os postorbitale, os jugulare, dan os quadratum. Os mandibula hewan ini mempunyai symphysis mandibularis yang panjang yaitu garis yang melintang di corpus mandibulae. Secara fungsional ukuran symphysis mandibularis berkaitan dengan adaptasi hewan terhadap diet makan.
