Abstract

Penelitian ini bertujuan untuk menganalisis performansi kabel N2XY pada sistem tiga fasa tegangan rendah dengan fokus utama pada pengaruh jatuh tegangan yang terjadi. Masalah jatuh tegangan dalam sistem distribusi listrik seringkali mengakibatkan turunnya kualitas pasokan daya, sehingga memerlukan analisis menyeluruh terhadap parameter sistem yang digunakan. Metode penelitian ini mencakup pengukuran langsung di lapangan, perhitungan manual menggunakan rumus dasar teknik listrik, serta simulasi dengan perangkat lunak ETAP 12.6.0 untuk memvalidasi hasil analisis. Hasil penelitian menunjukkan bahwa pada jarak 1,3 km dengan kabel N2XY berpenampang 4 x 70 mm² dan beban total sebesar 20,7 kW, diperoleh jatuh tegangan sebesar 33,3 V (8,31%) berdasarkan pengukuran, 33,89 V (8,47%) dari perhitungan, dan 25,8 V (6,5%) melalui simulasi ETAP. Disarankan untuk memperbesar penampang kabel guna meminimalisir jatuh tegangan dan menjaga kestabilan sistem distribusi daya listrik

Abstract

This article describes students’ writing skills in expository text based on the parallel class perspective for first-grade high school students. The research took place at the beginning of the even semester 2021/2022. The research used a descriptive-quantitative method. The population of the research were all students of class X SMA Negeri 6 Karawang who submitted answers to the writing skills test via a google form, which consisted of 137 students. There were 102 students who were selected through a simple random technique. Data were analyzed by using parametric inferential statistics with one sample t-test and a one-way Anova test via SPSS. The requirements for the homogeneity of variance and the normality of the curves of the Lilifors testing method were fulfilled through SPSS completely. It was found that the t-test of one sample was 0.411 at sig. 0.682 so that sig. 0.682 > 0.05, which means that the mean observation was 6.05 similar to the estimated mean of 6.00. The observed mean of 6.05 was equivalent to a relative value of 41.21%. This percentage included the low category. F value = 0.134 in sig. 0.970, so that sig. 0.970 > 0.05, which means that there is no difference in the mean of writing skill in writing exposition texts between class X-1, class X-2, class X-3, class X-4, and class X-5. The results contributed to related institutions regarding learning to write expository texts in a context of a gender perspective and parallel classes.

Abstract

Behavior is an organism's response to internal and external stimuli. By definition, behavior is an action performed by a living being in reaction to a stimulus. A consistent pattern of response to specific stimuli is categorized as behavior. An animal's ability to survive is reflected in these behavioral patterns. Each animal species has a unique way of acting, corresponding to their anatomical structure. Therefore, it is crucial to study animal behavior patterns in depth, given their critical role in maintaining ecosystem sustainability and balance. This research aims to investigate how the provision of stimuli to animals generates responses in the form of behavioral patterns towards their environment. By writing this research, it is hoped that the general public can understand more about animal behavior patterns. This research method is a literature review or literature review through several research articles, this review is done by searching from a database in the form of Google Scholar and obtaining 5 research articles.

Abstract

This study aims to produce valid and reliable Higher Order Thinking Skills instruments in learning the biology of ecology and environment material. The research is a Research and Development study with the ADDIE model. The research was conducted at SMA Negeri Kerinci. The sample in the study came from 2 biology education lecturers and 3 biology teachers. The instruments in this study were a 20-item multiple-choice HOTS test sheet and a validation questionnaire. Data collection techniques are tests and validation questionnaires. Indicators of Higher Order Thinking Skills are the ability to analyze, evaluate and create. Data analysis is quantitative and qualitative data analysis with the help of the SPSS version 16 application. The results showed that the Higher Order Thinking Skills instrument had a validation value of 0.724 with decent criteria and reliability of 0.972 with high criteria. These findings explain that the Higher Order Thinking SSkills(HOTS) instrument is very valid and reliable for use in ecology and environmental materials.
