Judul: Determination Of Calculation Quota Exporters Of Skin Reticulated Python (Python Reticulatus Scheider 1801) Environmental In Indonesia.
Abstrak: Trade of reptiles in regional and international have been increased every year. The trade of reptiles was divided into three namely pet reptile, consumption reptile and reptile skin. The trade of skin reptile greater than pest, because the skin of reticulated python is the most popular and to be excellent among exporters. Quotas export is all of number of quota exporter should be traded by exporter to international. This study aimed to identify of key variables exporter and formulation of calculation quota exporters of reticulated python. Data were collected from 44 exporter skin of phyton from June to November 2015. The methods used in this research were examination of administrative documents exporters and direct observation to the enclosure to 44 exporter skin of phyton reticulated. Processing and data analysis includes the identification of variables of exporter performance. Variables performance of exporter were export realization ofthe previous year (X1), labor (X2), finished product (X3), crusted product (X4), investment value (X5), yield (X6), PNBP (X7), state of export (X8), time of realization (X9), conservation activities (X10), chemicals (X11), and electricity (X12). Data was analyzed using pearson correlation, multikolinearitas and regression on SPSS version 23. Results showed that key variables that have a correlation to the calculation of quotas exporter and has no multikolenieritas between independent variables are finished product (X3) , the product crusted ( X4 ) , the investment value ( X5 ) , yield ( X6 ) , PNBP (X7) , time realization ( X9 ) , conservation activities (X10) and chemicals ( X11 ) . Based on the analysis of linier regression formula obtained quota determination exporter: Y = 2.001 + 0.002 X3 + 0.072 X4 + 0.080 X5 + 0.030 X6 – 0.384 X9 + 0.059 X10. The result of regression equation of adjusted R square is 0.916. It means that the quation of regression linear is 91.6% for calculation of quotas as it could be explained by finished product, products crusted, yield, investment, time of realization and conservation activities, while 8.4% is explained by variables that are not included in of this research. Variables were positively related to the calculation of export quotas include finished product (X3), product crusted (X4), investments (X5), yield (X6), and conservation activities (X10), while the variables that have a negative relationship is time of realization ( X9).

Judul: Tata Niaga, Karakteristik Habitat dan Parameter Demografi Sanca Batik (Python reticulatus Scheider 1801) yang Dipanen di Propinsi Kalimantan Tengah
Abstrak: Reticulated python (Python reticulatus) has 180.000 heads annual quota. Despite of the commercial use of this species, a good management of the habitat and population is needed for its sustainability. This research was aimed to identify trades, the habitat charactesictics, harvestings, demographyc parameters and morphometry of harvested reticulated python. The research area was within harvesting areas, management authority, snakes collectors and traders in six regency in Central Kalimantan Province. The research method for trades was done by interviewing several actors of management authority, snakes collectors and traders. The habitat was performed by measuring the environment variables at every plot of capturing and nesting habitat, neither the snakes were captured or not. Harvestings, demographyc parameters morphometry variables of harvested snakes at every plot of habitats, catchers and collector were calculated and measured. Descriptive statistical analyzes showed that traders structure were consisted of collectors, middle man and legal permit owner. Kruskal Wallis and Kolmogorov-Smirnov test showed that there was no habitat preference by the reticulated python. Harvesting estimation derived from location of survey was 26.73% at collector stage and about 31.95 % at middle man stage comparing to annual quota of Central Kalimantan Province. Capturing criteria was based on the size of body length, rather than the sex. The sex ratio of captured snakes in collectors was 1:0.72 and middle man was 1:1.07. The age class most captured both in collectors and middle men was the adult male (99% and 89% from all male). This trend occurred because the adult male has a similar size with the young female.

Judul: Persamaan Gelombang Permukaan Dalam Sistem Hamiltonian
Abstrak: Fluida adalah suatu zat yang bentuknya dapat berubah secara kontinu akibat gaya geser. Dua bentuk fluida yang dikenal adalah fluida yang berbentuk cairan dan gas. Dalam tulisan ini akan dibahas fluida yang berbentuk cairan. Persamaan yang memodelkan fenomena gelombang fluida di antaranya adalah sistem Hamiltonian. Persamaan ini berasumsi babwa fluida dalam keadaan ideal di mana fluida tak mampu mampat (inkompresibel), fluida tak rotasional (irrotasional).
