Judul: The Effect of Mechanical Door Modifications on Folding  Traps on Blue Swimming Crab Behavior
Abstrak: Kualitas dan kuantitas hasil tangkapan bubu rajungan dipengaruhi oleh konstruksi yang digunakan. Upaya untuk meningkatkan produktivitas bubu dapat dilakukan dengan memodifikasi bagian slope net. Tujuan dari penelitian ini yaitu mengidentifikasi tingkah laku serta membandingkan waktu yang dibutuhkan rajungan dalam menemukan pintu hingga masuk ke dalam bubu modifikasi dan bubu kontrol. Penelitian ini dilakukan menggunakan metode eksperimental di Laboratorium Hatchery AUP Banten. Data hasil penelitian dianalisis menggunakan analisis deskriptif dan statistik. Hasil penelitian menunjukkan terdapat delapan pola yang dibentuk rajungan untuk masuk ke dalam bubu modifikasi dengan pola terbanyak (22%) yaitu M5 (mendekati dari sisi kanan dan masuk melalui bagian tengah) dan lima pola untuk bubu kontrol dengan pola terbanyak (28%) yaitu K3 (mendekati bagian tengah bubu dan masuk melalui kiri pintu). Sedangkan waktu yang dibutuhkan rajungan dalam menemukan pintu bubu modifikasi dan kontrol tidak berbeda signifikan dengan masing-masing 102,1 detik dan 136 detik, dengan standard error (Se) sebesar 4,53 dan 4,52. Akan tetapi memiliki perbedaan yang signifikan untuk waktu yang dibutuhkan rajungan masuk ke dalam bubu dengan masing-masing 27,6 detik dan 47,05 detik, dengan standard error (Se) sebesar 13,3719 dan 20,7338., The quality and quantity of crab trawl catches are influenced by the construction used. Increasing the productivity of the traps can be done by modifying the slope part of the slope net. The purpose of this study was to identify the behavior and compare the time required by the crab in finding the door to enter the modified trap and control trap. This research was conducted using an experimental method at the AUP Banten Hatchery Laboratory. The data were analyzed using descriptive and statistical analysis. The results showed that there were eight patterns formed by crabs to enter the modified trap with the most patterns (22%) namely M5 (approaching from the right side and entering through the center) and five patterns for the control trap with the most patterns (28%) namely K3 (approaching the center of the traps and entering through the left door). Meanwhile, the time taken by crabs in finding the door of the modified and control trap was not significantly different with 102.1 seconds and 136 seconds respectively, with a standard error (Se) of 4.53 and 4.52. However, there is a significant difference in the time taken by the crab to enter the trap with 27.6 seconds and 47.05 seconds respectively, with a standard error (Se) of 13.3719 and 20.7338.

Judul: Folding Trap Door Construction Modification for Blue  Swimming Crab (Portunus sp.)
Abstrak: Produksi rajungan di PPN Karangantu cenderung menurun. Hal ini menunjukkan bahwa alat tangkap yang digunakan yakni bubu belum efektif, sehingga diperlukan modifikasi. Modifikasi yang dilakukan yaitu menghilangkan bentuk funnel dan diganti dengan pintu satu arah pada mulut bubu, sehingga tujuan dari penelitian ini adalah membandingkan respons dan tingkah laku rajungan terhadap bubu kontrol dan bubu modifikasi, terdiri dari pola pergerakan mendekati bubu serta waktu yang dibutuhkan untuk menemukan pintu bubu dan memasuki bubu. Metode yang digunakan pada penelitian ini adalah percobaan laboratorium. Hasil penelitian yang didapatkan yaitu pola pergerakan rajungan pada bubu modifikasi umumnya melalui bagian tengah pintu sedangkan pada bubu kontrol melalui bagian sisi funnel. Pola pergerakan memengaruhi waktu yang dibutuhkan rajungan untuk menemukan pintu dan memasuki bubu. Perbedaan waktu yang dibutuhkan rajungan dalam menemukan pintu bubu kontrol dan modifikasi menunjukkan perbedaan yang signifikan, namun waktu rajungan memasuki bubu tidak menunjukkan adanya perbedaan yang signifikan antara kedua jenis bubu, The production of blue swimming crab in Karangantu Archipelago Fishing Port tends to decrease. This indicates that the fishing gear used, namely the trap, is not effective, thus requiring modification. The modification involves removing the funnel-shaped entrance and replacing it with a one-way door at the mouth of the trap. The purpose of this study is to compare the responses and behavior of crabs towards the control trap and the modified trap, specifically examining their approach patterns towards the trap and the time taken to find and enter the trap. The method used for this research is a laboratory experiment. The results show that the movement pattern of crabs towards the modified trap mostly occurs through the center of the door, while for the control trap, it occurs through the sides of the funnel. The movement pattern affects the time taken by crabs to find the trap's door and enter it. There’s a significant difference in the time taken by crabs to find the door between the control and modified traps. However, there’s no significant difference in the time taken by crabs to enter the traps between the two types.

Abstrak: The development of open source softwares is still going rapidly nowadays, including open source operating systems for desktop computer, netbook, tablet PC, and smartphone. The open source operating systems have considerable contribution to open source software. Linux is an open source operating system that continues to grow since 1991. The characteristics in general Linux are free, can be distributed freely, and free to make changes in it. Linux in its development is divided into several distributions. Each distribution is made as a specific goal so that the operating system can focus on running the desired functions, such as multimedia, networking, education, etc. The objective of of this research is to develop and evaluate the ILOS distribution for multimedia by providing multimedia of open source packages. ILOSmedia uses Ubuntu10.10 and Remastersys as a tool to remaster. ILOSmedia is developed by installing multimedia packages that have been obtained based on the results of questionnaires from 30 respondents from three communities, which are KPLI Bogor, Linux.com forums, and Kaskus.us forums. ILOSmedia also uses the Realtime kernel as kernal Mutimedia. ILOSmedia testing is performed by 11 students of Computer Science who are members of FOKERZ community. The testing process is performed by executing ILOSmedia via live-cd and filled in a questionnaire. The test result shows that ILOSmedia has hardware compatibility on notebook and PC with good performance. As much as 72.727% of respondents believe that the size of the installer ILOSmedia of 1.34 GB and a minimum 10GB hard drive is normal. ILOSmedia has multimedia packages complete with the percentage completeness according to respondents is 45.455% are very complete and 54.545% are complete. Boot speed ILOSmedia have an average of 28.87 seconds and 90.91% of respondents consider that ILOSmedia have a desktop environment that is easy navigation
