Abstract

Green computing socialization was conducted at SMK Muhammadiyah 8 Medan on May 31, 2025, to enhance student awareness regarding environmentally friendly technology practices. The primary issue addressed was the need to build a collective responsibility towards the environment within the school's digital culture. The purpose of this study is to measure the level of student awareness and evaluate the effectiveness of the education program which utilized lectures, demonstrations, and interactive discussions. The research method used is descriptive with a participatory approach, collecting data through observation and questionnaires. The results indicated a significant improvement in understanding among the 27 participants, with 8 participants responding "very understood" and 14 participants responding "understood" regarding the material. The activity had a positive impact, fostering enthusiasm for applying energy-saving principles in daily life. These findings highlight the potential of green computing education to form a generation that is not only academically competent but also ecologically responsible.

Abstract

Penelitian  ini  bertujuan  untuk  mengembangkan  dan  melaksanakan program sosialisasi pengenalan Green Computing di lingkungan pelajar SMK Muhammadiyah 8 Medan, dengan tujuan meningkatkan kesadaran lingkungan di kalangan siswa dan masyarakat sekitar. Green Computing merupakan  pendekatan  dalam  penggunaan  teknologi  informasi  yang efisien  dan  ramah  lingkungan,  yang  mencakup  penghematan  energi, pengurangan  emisi  karbon,  serta  pengelolaan  limbah  elektronik  secara bertanggung jawab. Metode yang digunakan dalam penelitian ini adalah pendekatan  partisipatif  melalui  kegiatan  penyuluhan,  pelatihan,  dan demonstrasi  langsung  kepada  siswa  dan  masyarakat.  Kegiatan  ini melibatkan 27 peserta dari kelas Desain Komunikasi Visual (DKV) dan Akuntansi, yang terdiri dari 5 siswa dan 22 siswi disekitar sekolah. Materi yang  disampaikan  mencakup  definisi  Green  Computing,  dampak, manfaat, serta implementasi langkah praktis yang dapat diterapkan dalam kehidupan  sehari-hari  untuk  mengurangi  dampak  negatif  terhadap lingkungan. Hasil evaluasi menunjukkan peningkatan pemahaman yang signifikan  di  kalangan  peserta,  dengan  8  peserta  merespon  “sangat mengerti”,  14  peserta  merespon  “mengerti”,  dan  5  peserta  merespon “cukup mengerti”  dalam  kuesioner  yang  dilaksanakan  setelah  kegiatan. Selain  itu,  antusiasme  peserta  dalam  menerapkan  prinsip-prinsip  Green Computing dalam kegiatan sehari-hari juga meningkat.

Abstract

This study analyzes the customer queuing system at Warung Ayam Pecak by applying the First In First Out (FIFO) method combined with parallel processing to improve service efficiency. The selection of this topic is based on the problem of relatively long customer waiting times due to the sequential service process. Data collection was conducted through field observations to obtain patterns of customer arrivals, service duration, and cooking time under initial conditions using only one stove and one kitchen worker. Next, a simulation model was developed to compare the initial system with the proposed system, which implemented two parallel cooking processes. The simulation results showed that the application of parallel processing was able to reduce the Average Waiting Time (AWT) from 25 minutes to 2.82 minutes and the Average Waiting Process (AWP) from 11.82 minutes to 6.2 minutes. These findings indicate that the addition of simple resources, in the form of one stove and one worker, can significantly increase service throughput and reduce queue length. This study concludes that queue system optimization through the FIFO and parallel processing approaches is effective in improving the operational performance of small-scale culinary businesses.Keywords: Queue simulation, FIFO, Parallel Processing, Waiting Time, Operational Efficiency
