Abstract

Penulis mensimulasikan rangkaian buck converter pada controller turbin angin The Sky Dancer 500 W di PT Lentera Bumi Nusantara. Simulasi buck converter penting untuk di lakukan karena buck converter pada turbin angin berfungsi untuk menurunkan tegangan pada output yang menyebabkan tegangan output menjadi lebih kecil daripada tegangan input. Hal ini di lakukan agar tegangan yang masuk sesuai dengan konfigurasi baterai. Pada simulasi ini, penulis menggunakan rangkaian close loop. Cara kerja rangkaian close loop adalah apabila tegangan keluar dari buck converter belum sesuai dengan konfigurasi baterai, maka tegangan akan masuk ke rangkaian close loop untuk disesuaikan tegangannya sesuai dengan konfigurasi baterai. Berdasarkan hasil dari simulasi, dapat di simpulkan bahwa charging controller The Sky Dancer 500 W digunakan untuk membuat tegangan yang dihasilkan generator bisa disimpan ke baterai. Buck converter berfungsi untuk menurunkan tegangan yang dihasilkan generator dan membuatnya lebih stabil sebelum disimpan ke baterai agar umur baterai menjadi lebih panjang. Kata kunci: Controller, Close Loop, Buck Converter

Abstract

Stunting in children is a complex health problem with long-term impacts on physical growth, cognitive development, and future individual productivity. One contributing factor to stunting is poor environmental sanitation, particularly during pregnancy. This community service activity aims to increase the knowledge and awareness of pregnant women about the importance of environmental sanitation as a preventative measure against stunting in children. The activity was carried out in Rancangkencono Village, involving 12 pregnant women as participants. The implementation method included direct counseling, group discussions, and demonstrations of basic sanitation practices such as handwashing, using healthy latrines, and managing household waste. Evaluation was conducted by comparing pretest and posttest results to measure knowledge gains. The results showed an increase in the average knowledge score of participants from 55 in the pretest to 85 in the posttest. In addition, participants demonstrated positive changes in attitudes toward implementing clean and healthy living behaviors in the home environment. Data analysis showed that a participatory and contextual educational approach can increase the understanding and motivation of pregnant women to maintain environmental cleanliness for the health of their fetus and unborn child. Environmental sanitation education has proven to be an effective strategy in preventing stunting from pregnancy, so it needs to be implemented sustainably with cross-sector support at the community level.

Abstract

Academic reading is an essential competency for EFL learners, especially for those preparing for the IELTS examination, although it continues to create significant challenges. This study examines the issues encountered by Indonesian IELTS candidates in the reading section and analyzes the tactics they utilize to overcome these obstacles. A mixed-method approach was employed to collect data via questionnaires and open-ended responses from 24 participants in an IELTS preparation program in Ternate City. Quantitative data were evaluated using SPSS, and qualitative data were thematically interpreted to enhance the findings. Findings indicate that restricted vocabulary, time limitations, and comprehension challenges are the primary barriers faced by examinees. Participants indicated adopting multiple strategies to tackle these challenges, with skimming, scanning, highlighting important information, and employing contextual hints being the most commonly adopted techniques. The results highlight the significance of strategic instruction and vocabulary enhancement in preparing students for IELTS reading assessments. This study indicates that focused instruction and regular practice can improve learners' reading efficiency and performance in high-stakes language assessments.
