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.

Judul: Peningkatan Produktivitas Proses Budidaya Karet Alam dengan Pendekatan Green Productivity (Studi Kasus di PT. XYZ)
Abstrak: Indonesia is the second largest natural rubber producer in the world, with 28% of the total world production in 2010. In line with the growth of the world's automotive industry, the needs of rubber as a complementary synthetic rubber products will also increase. The main objective this research was to find the best alternative strategy to increase the productivity of the natural bber plantations through the green productivity (GP) approach. The case study was conducted at PT. XYZ, a private company which runs in the plantation and processing of natural rubber usinesses. The material flow analysis was performed by using green stream map to analyze the seven Treen wastes. The best alternative strategy was determined by using of AHP model and several design Improvements scenario. The measurement of the alternative strategy performance was rated as the ture GPI and compared with the value of current GPI, which had been calculated on a case study hat was done. The results of this research will be able to provide the best improvement productivity rategy, the level of company's productivity which has been achived, and the productivity levels of The implementation strategy chosen.

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.
