Abstract

Non- Non-Cash Food Assistance (BPNT) is a non-cash food social assistance from the government given to beneficiary families (KPM) of Rp. 200,000 per month which is given in the form of basic necessities by using an electronic card. The large number of residents who will be selected makes it difficult for village officials to make decisions on who is eligible or ineligible as recipients of non-cash food assistance every month. This research was conducted to design a decision support system for the eligibility of non-cash food assistance recipients by using the naïve bayes algorithm in order to help the Parit Baru Village apparatus every month in determining the eligibility of the next non-cash food assistance recipients, by perform Confusion Matrix calculations. From the results of the discussion carried out, it can be concluded that Naïve Bayes and the resulting rules had an accuracy rate of 95%, the Precision value was 94% and Recall was 100%. Therefore, the Naïve Bayes algorithm can be applied to the decision support system in determining the eligibility of recipients of non-cash food assistance.

Abstract

Pertumbuhan beban puncak Riau rata-rata 10 tahun mendatang sebesar 6,5% (RUPTL 2021-2030) dikarenakan pelanggan yang besar terutama rencana untuk pertamina hulu Rokan (400 MW), pelanggan pertamina RU II berpotensi memperluas pelanggan eksisting di Kawasan Industri (KID) Dumai. Pasokan listrik ke Dumai masih bersifat radial dengan mengandalkan transmisi Balai Pungut - Duri - Dumai. Apabila terjadi gangguan transmisi di GI Balai Pungut - Duri maka akan terjadi risiko tinggi terjadinya pemadaman listrik bagi GI yang memasok listrik ke pelanggan industri di Dumai. Untuk meningkatkan kehandalan jaringan di Riau untuk pasokan listrik ke Dumai maka perlu diterapkan sistem skema loop antara GI Siak - GI KID. Dengan hasil skenario II (looping KID-SIAK) yang menurun sebesar 39%, Skenario VIII (Ekspansi Beban di Vienna Pasca Looping KID-SIAK), dan Skenario X (Generator MPP Duri Mati Pasca Looping KID-SIAK) merupakan skenario yang paling aman untuk dilaksanakan dari nilai tegangan yang memenuhi persyaratan yang diizinkan oleh standar Aturan Jaringan Sistem Tenaga Listrik (GRID CODE), yaitu tidak kurang dari 10% dan tidak lebih dari 5% dari tegangan nominalnya pada ekspansi beban 12 MW.

Abstract

Nilai drop tegangan yang melebihi batas toleransi akan menyebabkan terjadinya pemadaman secara otomatis oleh sistem proteksi, untuk mengurangi daerah pemadaman listrik agar tetap tercapainya kondisi penyaluran tenaga listrik yang efisien dan maksimal salah satu cara dengan memanuver jaringan tersebut . Pada kasus ini Penyulang yang dimanuver adalah penyulang Suka Karya dengan Penyulang Taman Karya yang bertujuan untuk mengurangi pemadaman terutama pada daerah yang memiliki pelanggan prioritas. Untuk mengetahui seberapa besar drop tegangan dan rugi daya yang terjadi saat kondisi sebelum dan sesudah manuver beban pada penyulang ini perhitungan dilakukan dengan menggunakan software ETAP, simulasi terhadap penyulang dilakukan sebanyak 10 skenario berdasarkan data dari PT. PLN (Persero). Hasil penelitian ini untuk skenario manuver beban terbaik terdapat pada skenario ke 3 dengan jumlah beban 15610 kVA tidak terdapat drop tegangan yang melebihi batas toleransi dan tidak terjadi overload, sedangkan skenario terburuk terdapat pada skenario ke 1 dengan jumlah beban 23465 kVA terdapat drop tegangan di bus 8 yaitu 10,4% tegangan menurun menjadi 17,921 kV hingga ke bus 4 yaitu 18,17 % tegangan menurun menjadi 16,165 kV akibat dari kondisi jaringan yang mengalami over load. Untuk total rugi daya aktif dan reaktif sebelum manuver beban yaitu 1051,4 kW dan 3037,8 kVAR sedangkan sesudah manuver beban rugi daya aktif dan reaktif tertinggi terdapat pada skenario ke 1 dengan total 3957,4 kW dan 3981,7 kVAR.

Abstract

The International Community Service Program (PKM) has become a strategic tool in identifying and encouraging the use of appropriate technology in the development of higher education cooperatives. This study aims to explore the potential implementation of appropriate technology in the management and operational systems of the ANGKASA Malaysia Cooperative as a model for developing campus cooperatives in Indonesia. Through an observational approach, semi-structured interviews, and institutional document review, empirical data were obtained regarding the digitalization and information systems engineering practices implemented by ANGKASA. The study results indicate that technology integration based on the needs of cooperative members can improve service efficiency, financial accountability, and academic community participation. These findings serve as important reflections for higher education cooperatives in Indonesia to adopt similar adaptive and sustainable systems. Therefore, synergy is needed between educational institutions, technology developers, and the government to strengthen the digital cooperative ecosystem on campus.

Abstract

This research was motivated by the importance of using learning media that are attractive and appropriate to the characteristics of early childhood in introducing numbers and colors. Based on preliminary observations at Al Fath Kindergarten, Kedemangan Village, Muaro Jambi, it was found that some children still had difficulties recognizing numbers and colors and were less enthusiastic about participating in conventional learning activities. Therefore, the use of number and color puzzle media was considered an alternative to improve children's interest and learning abilities. This study aimed to describe the use of number and color puzzle media at Al Fath Kindergarten in Kedemangan Village, Muaro Jambi, to identify children's responses to the use of the media, and to determine the supporting and inhibiting factors in its implementation. This study employed a qualitative approach with a descriptive research design. The research subjects consisted of classroom teachers, the principal, and children of Al Fath Kindergarten in Kedemangan Village, Muaro Jambi. Data were collected through observation, interviews, and documentation. Data analysis used the Miles and Huberman model, including data reduction, data display, and conclusion drawing. Data validity was ensured through source triangulation and technique triangulation.The results showed that the use of number and color puzzle media had been implemented effectively in learning activities. Teachers used puzzle media as a learning-through-play tool to introduce numbers and colors to children. Children's responses to the use of puzzle media were very positive, as indicated by increased enthusiasm, participation, and involvement during the learning process. The use of puzzle media also helped improve children's ability to recognize numbers and colors, enhance concentration, develop logical thinking skills, and improve fine motor skills. Supporting factors included teacher creativity, the availability of learning media, and support from the school. Meanwhile, inhibiting factors included differences in children's abilities, limited numbers of puzzle media, and children's short attention spans. Keywords: puzzle media, numbers and colors, early childhood, learning, kindergarten.
