Abstract

Phonetic problems in Arabic are classic problems studied since the age of Al-Khalil bin Ahmed Al-Farahidi (d. 170 AH). This science is still being studied and developed to this day and has even become something that cannot be separated from linguistics. Ibn Taymiyah was an expert in religious knowledge who paid great attention to sound and its meaning. On this basis, through the use of semantic descriptive analysis, this research seeks to collect opinions regarding the meaning of sounds and at the same time compare them with what ancient and contemporary phonetic scholars have put forward regarding this issue. Among the results obtained from this research is the correspondence between the sounds in Arabic and the meaningThe phonetic intensity of a sound corresponds to the semantic intensity of its meaning, and vice versa. This study is really needed by Arabic language students, because some of them have difficulty memorizing Arabic vocabulary which is so large and cannot be distinguished from one another except by just one letter or just one vowel. Not only that, it is hoped that this research can contribute to knowledge on the topic of discussing semantics and phonetics.

Abstract

Abstrak - Di Indonesia masih banyak dijumpai daerah-daerah yang belum teraliri arus listrik PLN. Daerah-daerah tersebut menggunakan pembangkit listrik tenaga surya yang biasa dikenal dengan PLTS sebagai suplai energi listriknya. Energi listrik tersebut digunakan untuk keperluan sehari-hari seperti sebagai suplai penerangan rumah tangga. Pada umumnya lampu penerangan yang digunakan rumah tangga menggunakan tegangan AC 220-240 volt. Pada kondisi tertentu lampu penerangan rumah tangga dapat dinyalakan menggunakan tegangan DC. Tegangan DC berkisar dari 80-125 volt dapat digunakan untuk menyalakan lampu penerangan. Untuk itu agar PLTS dapat digunakan secara langsung untuk menyalakan lampu penerangan perlu dilakukan penyamaan level tegangan antara tegangan keluaran PLTS dengan tegangan suplai lampu penerangan.  DC to Dc converter dengan topologi boost konverter digunakan dalam penelitian ini.Tegangan DC sebesar 12 volt dari keluaran PLTS dinaikkan level tegangannya menjadi sekitar 95 volt DC. Output DC to Dc converter ini dapat di gunakan untuk menyalakan lampu led penerangan sebanyak 8 buah. Setelah dilakukan pengujian secara empiris didapatkan hasil, efisisensi DC to DC converter sebesar 70,7 % dengan arus kurang dari 35 mA.Kata kunci: Lampu Penerangan, Solar Cell, DC to DC Converter, Tegangan, Arus. Abstract - In Indonesia, there are still many areas that have not been connected to PLN electricity. These areas use solar power plants commonly known as PLTS as their electricity supply. The electricity is used for daily needs such as household lighting supplies. In general, household lighting uses 220-240 volt AC voltage. Under certain conditions, household lighting can be turned on using DC voltage. DC voltage ranging from 80-125 volts can be used to turn on lighting. For this reason, so PLTS can be used directly to turn on lighting, it is necessary to equalize the voltage level between the PLTS output voltage and the lighting supply voltage. A DC to DC converter with a boost converter topology is used in this study. The DC voltage of 12 volts from the PLTS output is increased to around 95 volts DC. The output of this DC to DC converter can be used to turn on 8 LED lighting lamps. After empirical testing, the results obtained were that the efficiency of the DC to DC converter was 70.7% with a current of less than 35 mA.Keywords: Lighting, Solar Cell, DC to DC Converter, Voltage, Current.

Abstract

Abstract: Limited access to laboratory facilities in vocational education, particularly in the field of mechanical engineering, often becomes a major obstacle in providing safe and industry-relevant practical experiences. Vocational high school (SMK) teachers in Bontang face challenges in delivering effective and efficient practice-based learning. This study aims to develop a Mixed Reality (MR) Laboratory as an innovative solution for simulating mechanical engineering practices. The MR Mixed Lab is designed to provide interactive learning experiences through mixed reality technology, enabling teachers to guide students in understanding machine assembly and disassembly concepts without the risk of equipment damage or injury. In addition, MR implementation can reduce operational practice costs and increase the frequency of training within a more realistic learning environment. The research method employed is Research and Development (R&D) with the ADDIE model, which consists of the stages of Analysis, Design, Development, Implementation, and Evaluation. The development process involves user needs analysis, system design, creation of interactive 3D models, and effectiveness testing involving vocational school teachers. Data are collected through observation, questionnaires, and interviews to evaluate usability, learning effectiveness, and user engagement. The expected outcome is an MR Lab prototype that is relevant, feasible, and beneficial for vocational education. Keywords: Mixed Reality (MR), Practice Simulation, Mechanical Engineering, Digital Laboratory, Teacher Abstrak: Keterbatasan akses laboratorium dalam pendidikan vokasi, khususnya pada bidang teknik mesin, sering menjadi kendala utama dalam memberikan pengalaman praktik yang aman dan relevan dengan kondisi industri.
