Judul: Peningkatan produktivitas pada proses produksi karet alam dengan pendekatan green productivity (studi kasus di pt. xyz)
Abstrak: The productivity issues are the integral part in the industrial world. These because the productivity is one of the industrial sustainability indicators in the future. Productivity could be Improved by reducing the waste generated. The productivity improvement of natural rubber production process in the PT. XYZ have been accomplished. The current state analysis of green productivity measurement was used by using the green productivity indexing (GPI) method. The current state GPI measurement result for the production of ribbed smoked sheet is 0.269 while the brown crepe products result is 1.089. There are four alternative strategies to improve the green productivity in the PT. XYZ based on expert opinion. By using Analytical Hierarchy Process method, He reuse of water process was obtained as the alternative strategy choosen, with 0.336 for the weight value. The implementation of the selected alternative strategy shows the reducing of the Environmental impact as 3.565 for the production of ribbed smoked sheet and 0.538 for the Production of brown crepe. The implementation of the selected alternative strategies also shows the Green productivity increasing to 0.690 for the production of ribbed smoked sheet with 2.565 GP ratio and 3.889 for brown crepe product with 3.571 GP ratio.

Abstrak: Low productivity and quality of pre-processed rubber and lack of environmental consideration is the main obstacle in the development of the rubber industry. The main objective of this research was to obtain productivity improvement formulation of pre-processed rubber with green productivity approach. Research applied 3 stages of analysis. First, institutional analysis in the smallholder plantations using ISM to identify the contextual relationships between subelemen where farmers are the most important element. Second, production process analysis by mapping each stream process using GVSM and the initial GPI calculation. Third, pre-processed rubber quality analysis using QFD, and produced raw materials handling activities and freezing latex, need to be considered in producing a quality pre-processed rubber. After further analysis to obtain productivity improvement formulation, AHP then applied to weigh the improvement alternative. Based on the overall analysis, the best scenario obtained a GPI value of 1.875. It is better compared to the initial GPI of 1.138

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.
