Abstract

First, we analysed alabcore catch data based on time, positions, and layer alabcore caught and ROMS result data monthly climatology data for temperature, salinity. current velocity, and sea surface height for 2005–2008. Then, we analyzed the relationship between catch data and ROMS data by combining the statistical method of regression trogh origin (RTO) and geographic information system (GIS). Three model RTO were generated with the abundance of albacore tuna as a response variable, and temperature, salinity. current velocity, and sea surface height as predictor variables. All of the predictors of temperature, salinity. current velocity, and sea surface height were highly significant (P < 0.001) to the number of albacore tuna. Values of temperature, salinity. current velocity, and sea surface height in albacore tuna preferences ranged from 220 to 230 C, 34.79 to 34.84 Psu, 0.01 to 0.03 m/s and 0.66 to 0.70 m, respectively. Validation of the predicted number ofalbacore tuna with the observed value was significant (P < 0.05, r2 = 0.60). sea surface height was the most important environmental variable to the number of albacore tuna caught, followed by temperature, salinity and current velocity.

Abstract

One of the problems in remote access to the system is the act of hacking to illegally gain access rights to a system. Therefore the need for an additional mechanism in user authentication in addition to the username and password parameters. The port knocking method is an option that can be implemented in this problem. Port knocking is a security system that functions to open or close access to certain ports by using a firewall on network devices by sending certain packets or connections. The connection used can be in the form of TCP, UDP, or ICMP protocols. The network system development method used in this research is the PPDIOO method developed by CISCO, where the cycle sequence includes: . prepare (preparation), Plan (planning), Design (Design), Implement (Implementation), Operate (Operation) and Optimize (Optimization). The result of implementing the Port Knocking method on a system on a computer network is that the system will refuse if the login activity on the system does not or sends additional parameters incorrectly, besides that the network admin can find out the activity on the network system if someone from outside fails when accessing the system through the port. so that actions can be taken according to system security requirements.

Abstract

Pada akhir masa belajar siswa SMK umumnya dilaksanakan Uji Kompetensi Keahlian (UKK) dalam rangka mengukur pencapaian kompetensi dari siswa tersebut. Aspek keahlian yang dinilai pada UKK di SMK Bakti Pangkalpinang meliputi keterampilan siswa dalam mendesain case dan cover DVD (Digital Video Disc) serta memproduksi video sesuai dengan tema yang ditentukan. Tidak menutup kemungkinan terdapat beberapa siswa yang belum mampu mengoperasikan software editing multimedia secara baik. Untuk mengatasi masalah tersebut, akan dilakukan workshop untuk meningkatkan keterampilan siswa dalam menggunakan software editing multimedia satu minggu sebelum UKK. Berdasarkan hasil evaluasi, workshop yang telah dilaksanakan mampu meningkatkan keterampilan peserta dalam menggunakan software editing multimedia secara efektif, yaitu rata-rata sebesar 9,88%. Setelah mengikuti workshop, predikat kompetensi dari 34 peserta didominasi dengan kompeten sebanyak 52,94%, disusul sangat kompeten sebanyak 41,18%, dan cukup kompeten sebanyak 5,88%.
