The accuracy of the study period can be determinant the students to pursued undergraduate degree. The available data indicated that only 30% of students can graduate <5 years, the rest graduate > 5 years and became non-active students. To overcome of low graduation rate is needed the system to determine the relationship between the masters students with study period that taken by the students. The use of data mining techniques in this system is expected to provide insights that were previously hidden in the data warehouse to be valuable information. By utilizing data mining techniques particularly algorithm ID3, then the researchers made an application to find a pattern that can predict the future of a students study period based on the data from students and academic score. The student data, scores, and the study period integrated into the data training. The data training is processed into a decision tree based on the calculation of the gain and entropy. From that tree made a rule that can predict a students study period. From 140 data training and 20 data testing with 6 kinds of attributes input and 2 kinds of target attributes, can be obtained by the accuracy of the ID3 prediction result for 85%, while the error rate prediction results for 15%.Â Keywords : Optimasi, Jumlah Mahasiswa Asia, Prediks, Induksi Decision Tree

Salah satu upaya peningkatan kedisiplinan SMK (Sekolah Menengah Kejuruan) Mahardika Malang yaitu mewajibkan siswa untuk datang di sekolah tepat waktu. Disinilah sangat diperlukan kesadaran para peserta didik untuk mentaati peraturan atau tata tertib yang berlaku. Jika ada peserta didik yang tidak disiplin datang tepat waktu di sekolah yaitu terlambat datang di kelas, sementara peserta didik yang lain sudah mulai mengikuti proses pembelajaran di kelas, maka kedatangan peserta didik yang terlambat tersebut mengganggu jalannya pembelajaran. Dalam penelitian ini peneliti akan memberikan solusi untuk meminimalisir keterlambatan dengan pemanfaatan teknologi perekam kehadiran siswa menggunakan QR (Quick Respons) Code. Dengan adanya teknologi ini maka akan sangat membantu dalam pendeteksian siswa yang sering hadir terlambat dan dapat merekam data tersebut ke dalam database, sehingga wakil kepala sekolah bagian kemahasiswaan akan dapat dengan mudah mengevaluasi serta memantau kedisiplinan siswa. Hal ini juga dapat meningkatkan motivasi siswa agar datang tepat waktu. Perekaman kehadiran siswa dengan QR code ini memberikan beberapa keuntungan kepada para penggunanya, baik untuk wakil kepala sekolah bagian kesiswaan maupun siswa SMK Mahardika, siswa dapat dengan mudah melakukan presensi atau perekaman kehadiran dengan menunjukkan dan mendekatkan kartu kehadiran (sudah dipasang QR code) pada PC (Personal Computer) di depan gerbang sekolah, sehingga dapat memotivasi siswa untuk datang tepat waktu. Perekam Kehadiran Siswa dengan QR code ini dapat terintegrasi dengan sistem informasi manajemen sekolah yang terdiri dari data siswa, jadwal sekolahÂ (setiap matapelajaran siswa), daftar ketidakhadiran siswa, rekap presensi siswa dan pusat pengumuman penting untuk siswa. Sehingga dengan adanya integrasi ini, sistem menjadi lebih banyak memberikan manfaat untuk semua pihak, baik untuk wali siswa maupun SMK Mahardika Malang.Kata kunci : Perekam Data Kehadiran,Â QR code, SMK Mahardika Malang.

Sistem pentanahan atau grounding yang baik diharapkan dapat melindungi perangkat elektronika, baik secara langsung ataupun secara tidak langsung jika terjadi sambaran petir saat terjadi hujan. Karakteristik dan kondisi tanah merupakan salah satu faktor yang dapat mempengaruhi nilai pentanahan atau grounding. Pada penelitian ini dilakukan kegiatan pengukuran pentanahan atau grounding pada kondisi tanah berbeda, yaitu pada kondisi tanah berair atau tanah liat, tanah kering, tanah berbatu, tanah pasir dan tanah rawa. Penelitian ini bertujuan untuk mengetahui besarnya tahanan pentanahan atau grounding. Metode pengukuran menggunakan tiga titik (three point methode) dan empat titik (four electrode methode) dengan menancapkan elektroda batang ke dalam tanah. Nilai resistansi tahanan yang tertampil pada alat ukur (Earth Resistance Tester) akan semakin kecil jika penanaman elektroda ditanam lebih dalam dan adanya penambahan batang elektroda, serta jarak antar elektroda diatur 5 sampai 10 meter.

The problem of telecommunication device in BTS shelter typically hot, up and drop voltage. The damage of telecommunication device will interrupt communication between receiver and transmitter. This final project proposes a benefit for telecommunication device in order to maintain the temperature of telecommunication device appropriate with the function. This dc cooler for telecommunication device can work automatically using Arduino Uno.This tool utilizes work princip of a peltier element which has the side absorb heat and removing heat and can be supplied by direct current as voltage source. The normal temperature of telecommunication device ranged from 22oC until 26oC. When the temperature of the telecommunication device exceeds normal temperature thenthis tool will be active and when the temperature of the telecommunication device is back to normal then this tool will be automatically off. The temperature of the telecommunication device also can monitored by LCD and smartphone with Bluetooth as media. DHT11 sensor in this tool can work well with error 2,71%. The LCD can display characters letters and numbers when given input voltage 3.9volt and Bluetooth can connected at distance less than 15 metres without the obstacle and at distance less than 4 meters when there are obstacle.

Bandung Health Office as a Health Agency that always provides quality services is currently focused on handling pandemics, especially in the implementation of vaccination programs as a strategy to combat the COVID-19 outbreak. Therefore, monitoring of complaints experienced by the community after vaccination is required. The problem experienced today is the unavailability of containers to accommodate and manage data on COVID-19 vaccination complaints using the information system. The purpose of this research is to design a website-based information system that supports the process of monitoring and handling COVID-19 vaccination complaints in the Bandung Health Office by presenting informative and transparent data so as to facilitate the public in reporting and obtaining complaint information easily. The system development method uses waterfall model, while the system functional design method uses object-oriented modeling approach with Unified Modelling Language (UML). Black box test results obtained a 100 percentage of system functionality success. Evaluation test results with System Usability Scale (SUS) questionnaire obtained the final test score of 77.6 with Acceptable category and B Grade Scale. So based on the test results, the system can run easily according to the needs of the user. This research resulted in a web-based information system that makes it easier for health workers to efficiently manage COVID-19 vaccination complaint reporting data.
