Judul: Kajian Peluang Implementasi Produksi Bersih pada Industri Kertas di PT X.
Abstrak: Kajian peluang implementasi produksi bersih di industri kertas perlu dilakukan untuk meminimalkan limbah yang dihasilkan dan meningkatkan pemanfaatan limbah. Penelitian ini mengkaji peluang implementasi produksi bersih melalui identifikasi tahapan proses, identifikasi permasalahan, identifikasi peluang produksi bersih, analisis kelayakan alternatif dari aspek teknis, lingkungan dan finansial serta pemilihan prioritas peluang produksi bersih dengan Metode Perbandingan Eksponensial (MPE). Proses yang terjadi pada pembuatan sack kraft yaitu proses penyiapan bahan, pembentukan lembaran, pengepresan, pengeringan, penggulungan dan pemotongan. Skala produksi sack kraft pada kasus ini adalah menggunakan 110 ton afval kardus per hari yang rata-rata menghasilkan sack kraft 90.742 ton, kertas gagal 3.65 ton, sisiran 2.443 ton, kertas cacat 4.915 ton dan 8.25 ton limbah padat. Berdasarkan hasil penelitian teridentifikasi permasalahan yaitu sering terjadi jam henti mesin, mesin mengalami kerusakan, terbentuknya limbah padat yang belum termanfaatkan, kertas gagal, sisiran kertas dan kertas cacat. Alternatif yang direkomendasikan adalah pembuatan pelet sebagai subtitusi bahan bakar (PBP 0.1 tahun dan B/C ratio 8.31), pembuatan dan pelatihan Standar Operasional Prosedur (SOP) maintenance mesin (PBP 3.9 tahun dan B/C ratio 1.3), dan pelatihan Good Manufacturing Practice (GMP) (PBP 0.63 tahun dan B/C ratio 2.58). Urutan penilaian prioritas peluang produksi bersih menggunakan MPE yaitu pembuatan dan pelatihan SOP maintenance mesin, pelatihan GMP dan pembuatan pelet sebagai substitusi bahan bakar.

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: Posisi Filogenetik Kura-Kura Carettochelys Insculpta  (Reptillia: Testudinata)
Abstrak: Carettochelys insculpta is an endemic freshwater turtle of southern Papua and northern Australia. Phylogenetic position of this turtle is remain unresolved until now. Most of the research conducted show close relationships of C. insculpta and members of Trionychidae family. However, some of the research show distance between C. insculpta and members of Trionychidae family. This research is conducted to analyze phylogenetic relationship between C. insculpta and other members of Testudinata using 12S rRNA, 16S rRNA, and both gene as markers. DNA samples were obtained from three different organisms of C. insculpta. Two species used as outgroups were Alligator mississippiensis and Iguana iguana. Phylogenetic analysis was carried out using Neighbor-Joining method with Felsenstein 1981 (F81) modeltest. A polytomy tree of Testudinata was produced by using 12S rRNA gene. However, analysis using 16S rRNA and both genes as markers confirmed that C. insculpta was located between the Chelonidae and the Trionychidae family.
