Judul: The Optimalization of Local cricket (Gryllus bimaculatuc de geex) Care Management at Production Time
Abstrak: The cricket culture in our country is highly supported by climate, weather, the existence of land, and kind of cricket around us. This culture has been doing to evade from scarcity and destroyed. On that purpose, we need the cricket culture continuously to avoid those things from happening. The research was done in the Laboratory of Cattle NRSH (Non Ruminansia dan Satwa Harapan), Department of Cattle Production Science, Cattle Ranching Faculty, Bogor Institute of Agriculture. The research was done since April until May 2000. The aim of this research is to learn how the influence of density per a wide and vegetable food (Brassica juncea and Carica papaya) to eggs production for local cricket species i.e. Gryllus bimaculatus de geex at the production time. The variable evaluated in this research are; production, average of egg production per head, feed consumption (concentrate and vegetables) as the supported data. The data were analyzed by ANOVA (Analysis of Variance). If the result shows the influence of each treatment before, then the analysis is continued with the advance test, LSD.

Judul: Performa Jangkrik Alam (Gryllus mitratus) dengan  Media dan Durasi Pengangkutan yang Berbeda
Abstrak: Jangkrik merupakan salah satu jenis serangga yang memiliki siklus hidup cepat, konversi pakan tinggi, penggunaan lahan rendah dan berprotein tinggi. Tingginya permintaan konsumen terhadap jangkrik mengharuskan produsen jangkrik untuk mendistribusikan jangkriknya, namun tidak memperhatikan pengangkutan jangkrik alam yang dapat mempengaruhi performanya. Penelitian ini bertujuan untuk menganalisis pengaruh media dan durasi pengangkutan yang berbeda terhadap performa jangkrik alam Gryllus mitratus. Penelitian ini menggunakan jangkrik alam Gryllus mitratus sebanyak 13,5 kg, klaras (daun pisang kering) dan egg tray yang diangkut selama 2 jam, 3 jam, dan 4 jam. Peubah yang diamati meliputi persentase susut bobot dan mortalitas. Penelitian ini menggunakan Rancangan Acak Lengkap pola faktorial dengan dua faktor yaitu durasi dan media pengangkutan. Data dianalisis ragam (ANOVA) dan hasil analisis yang berbeda nyata dilanjutkan dengan uji Duncan. Hasil penelitian menunjukan bahwa media tidak berpengaruh nyata terhadap susut bobot dan mortalitas, dan durasi perjalanan tidak berpengaruh nyata terhadap susut bobot jangkrik namun berpengaruh nyata terhadap mortalitas., Crickets are one type of insect that has a fast life cycle, high feed conversion, low land use and high protein. High consumer demand for crickets makes many cricket producers distribute the crickets, but do not pay attention to the transportation of cricket which can affect their performance. This study aims to determine the effect of different media and transport duration on the performance of Gryllus mitratus cricket. This study used 13.5 kg of Gryllus mitratus cricket, dried banana leaves, and egg tray transported for 2 hours, 3 hours, and 4 hours. The observed variables included percentage of weight loss and mortality. The data were analyzed for variance (ANOVA) and the results of the analysis were significantly different, followed by the Duncan test. The results showed that the media had no significant effect on weight loss and mortality, and transport duration had no significant effect on cricket weight loss but had a significant effect on mortality.

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).
