A major factor in the power system operation is the desire to maintain system security. System security involves a design to keep the system operating in the event of interference or failure. Interferences in electrical power systems are divided into generator, transmission, and load. Failure or interference of the transmission network results in a contingency of the transmission lines that can cause voltage in the bus and overload in the transmission lines, so it is very necessary to overcome the problem with a contingency analysis simulation to find solutions to problems caused by the disconnection of the transmission line. One of the contingency analysis methods is the 1P1Q (performance contingency index) method where the 1P1Q method lists the worst contingency impact on the electric power system to help engineers to solve problems and determine their next steps when contingencies occur. In the study, the Newton raphson's methods were used to determine the power flow in electrical systems at normal conditions or contingency. Calculating the value of the contingency index in times of interference or failure using the 1P1Q method. The results show that the worst impact or highest-ranking performance index for the Madura 150 kV electric power system occurs in the infinity-base scenario where two lines are overloaded and exceed the maximum value limit of the transmission line power of the infinity-gilitimur channel of 157.5 MW with a maximum value limit transmission line of 92,359 MW and gilitimur-bangkalan of 149 MW with a maximum value limit of transmission line of 88,616 MW. So there is prevention with load shedding of 87,638 MVA with scenario 6 in table 4:24 of load shedding on the bus Sampang, Sumenep, Pamekasan because by shedding loads of 95,528 MVA the power flowing at infinity-gilitimur becomes 72.9 MW.

AbstrakLulusan Sekolah Menengah Kejuruan (SMK) bisa melanjutkan ke perguruan tinggi tidak hanya lulusan Sekolah Menengah Atas (SMA) saja. Peserta didik SMK dapat mengembangkan potensi di perguruan tinggi dengan prodi yang sesuai dengan jurusan yang digeluti untuk menjadi teknisi yang handal dibidangnya. Dalam penelitian ini terdapat seberapa besar animo peserta didik SMK prodi keahlian teknik komputer dan informatika untuk melanjutkan studi ke perguruan tinggi dengan prodi yang sebidang serta faktor internal dan eksternal yang mempengaruhinya. Penelitian ini dilakukan pada peserta didik SMK Negeri prodi keahlian teknik komputer dan informatika kelas 12 tahun ajaran 2018/2019 Se-Kota Malang dengan jumlah sampel 559 peserta didik dan menggunakan analisis statistik deskriptif. Hasil analis yang dilakukan berhasil mendapatkan 72,63% peserta didik ingin melanjutkan ke perguruan tinggi dan 27,37% memilih untuk tidak melanjutkan. Kecenderungan animo peserta didik yang ingin melanjutkan perguruan tinggi berada pada kategori tinggi yaitu 56,15%. Presentase skor faktor yang mempengaruhi yaitu, faktor dari dalam diri sendiri 82,53% berada pada kategori sangat tinggi, faktor lingkungan keluarga 79,58% berada pada kategori tinggi, dan faktor lingkungan sekolah 74,62% berada pada kategori tinggi. Kemudian sebanyak 70,93% peserta didik memilih prodi yang sebidang. Penelitian ini berhasil mengungkap: (1) Kecenderungan animo berada pada kategori tinggi; (2) presentase skor faktor dalam diri sendiri lebih besar; (3) sebagian besar memilih prodi yang sebidang; (4) prodi teknik informatika paling banyak diminati. Kata kunci: animo, faktor mempengaruhi animo. AbstractGraduates of Vocational High School also could continue to college, not only graduates of Senior High School. Students of Vocational High School could develop their potentials in college by choosing the right major that suited their majors that they had been learned to be capable technicians in their own fields. In this research, there could be found how much Vocational High School students of Computer and Informatics Engineering were interested to continue their studies to college with the same major and internal and external factors that affected it. This research was done to Public Vocational High School students with Computer and Informatics Engineering as their major of grade 12 and year 2018/2019 in Malang City with the total of sample was 559 students and using desctiptive statistical analysis. The result of analysis that was done showed that 72.63% students wanted to continue to college and 27.37% chose not to continue to college. The interests tendency of students who wanted to continue to college was in high level, which was 56.15%. The percentage of score of the factors that affected it were 82.53% internal factor which was in very high level, 79.58% family environmental factor which was in high level, and 74.62% school environmental factor which was in high level. Then, 70.93% students chose major that had the same field. This research discoveried: (1) intere...
