Judul: Peningkatan Produktivitas Proses Produksi Ban Motor dengan Pendekatan Produktivitas Hijau (Studi Kasus di PT. XYZ)
Abstrak: Indonesian rubber Industries has the lower productivity among other rubber producer countries. Productivity issue was important part in the industry so low productuivity needed productivity improvement. The main objective of this research was to obtain productivity improvement formulation of motorcycle tire production process with green productivity approach. Research included two kinds of analysis. First, production process analysis was done by mapping each stream in production process used GVSM and mass balance also the initial GPI calculation. Second, sustainability analysis using MDS and produced v sustainability degree of motorcycle tire agroindustry. After further analysis to obtain productivity improvement formulation, then AHP applied to weigh the improvement alternative. Sustainability index of economic dimension was less sustain (LS) meanwhile sustainability index of social and environment were sustain enough (SE). Based on the overall analysis, the GPI initial was 1.081 with environmental impact was 1.073 and economic indicator was 1.160. Best scenario which was raw materials characteristics control also reuse of water and material obtained GPI value 1.123 with environmental impact was 1.040 and economic indicator was 1.168. On future, GP measurement needed depth analysis of motorcycle tire production process and integration system so could produced better improvement scenario.

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: 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.
