Judul: Kajian Peluang Implementasi Produksi Bersih Di Industri Pengolahan Karet (Studi Kasus di PT Condong Garut)
Abstrak: Rubber processing industry uses the resources of large amounts of water. This causes the rubber industry has to deal with various types of wastes in the form of liquid and solid wastes and the generation of waste gas of pungent odor. Environmental problems, as a result of these activities can be minimized by applying cleaner production. Cleaner production aims to increase the efficient use of raw materials, minimize waste and the risk of direct contamination at the source. The cleaner production alternatives which are potential to be applied are good housekeeping, collects rubber particles in rubber trap, use of coagulant antibacteria, and giving incentive for industry that apply cleaner production. The total investment of these option is Rp 660.000,- with payback period (PBP) of 0,28 bulan. The use Liqiud Smoke may reduce the RSS processing cost around 17,6%, and avoid carbon dioxide pollution. The results of AHP suggests that the environment is the most important factor in the implementation of cleaner production and the most important actor is the industry. Strategy to implement good housekeeping is the most important strategies that are generated from the AHP. This result indicates the similarity of field data analysis and expert survey that good housekeeping is the most important proper strategy for implementing cleaner production at PT Condong Garut.

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.

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.
