Abstract

This research aims to determine student learning outcomes after implementing the Project-Based Learning model in programming and microcontroller application subjects at SMK Negeri 1 Koto XI Tarusan. This type of research is initial experimental research (Pre-Experiment) with a one-group pretest posttest design. The research subjects were students of class XI Electronic Engineering at SMK Negeri 1 Koto XI Tarusan for the 2024/2025 academic year, totaling 26 students. The research results show that the use of the Project-Based Learning model can improve student learning outcomes. These results are seen from the psychomotor domain in the form of skills assessment sheets and student learning outcomes assessments in the form of pretests and posttests. Based on data analysis analyzed using the N-Gain Score formula, a result of 0.45 was obtained, which is included in the medium category. The pretest results obtained were 34.61% in the low category, the posttest results obtained were 84.61% in the very high category and the skill results obtained were 92% in the very skilled category. In this way, the Project-Based Learning learning model improves student learning outcomes in the subjects of programming and microcontroller applications.

Abstract

This study aims to process the use of Audio Visual Media in Increasing Student Learning Motivation in SKI Subjects in class VII MTs Darussa`adah Petanahan and to find out the increase in student motivation after applying Audio Visual media to SKI learning in Class VII MTs Darussa`adah Petanahan. This research is a classroom action research conducted in two cycles, with two meetings in each cycle. The subjects of this study were SKI subject teachers and class VII students. The data in this study were taken using data collection techniques in the form of tests and non-tests. The results showed that there were changes in the pre-action results, cycle I, and cycle II. In the pre-action, only about 27% had motivation to learn. In cycle I, the percentage increased to 49%. Then, after reflection on cycle II, student motivation reached 86%.

Abstract

Gula pasir merupakan kebutuhan pokok yang sangat penting bagi rumah tangga dan masyarakat terutama dalam hal pangan. Salah satu hal yang perlu dilakukan untuk menghasilkan gula pasir yang baik adalah dengan melakukan proses ekstraksi nira. Parameter penentuan mutu gula berdasarkan SNI 3140.3:2010 adalah kekeruhan. Salah satu faktor yang mempengaruhi nilai kekeruhan nira encer adalah pH. Semakin tinggi nilai pH maka semakin rendah nilai kekeruhan getah encer. Metode penelitian yang digunakan dalam proses ekstraksi nira adalah dengan menggunakan metode eksperimen langsung. Nilai kekeruhan terendah pada shift 1 pada pH 6,98 sebesar 91 NTU, pada shift 2 pada pH 6,85 sebesar 94 NTU, pada shift 3 pada pH 7,30 sebesar 94 NTU. Hasil dari proses ekstraksi nira ini berupa nilai %Brix, %Pol, dan HK. Semakin tinggi suhu imbibisi maka diperoleh nilai %Brix, %Pol, dan HK tertinggi dengan nilai %Brix 13,64%, %Pol 10,04%, dan HK 73,61 tertinggi pada mill I pada suhu 95°C. Hasil ekstraksi getah tertinggi dapat digunakan dalam pembuatan Gula Kristal Putih (GKP).

Abstract

Product quality is one of the key factors influencing consumer purchasing decisions, especially in an increasingly competitive market. This study aims to systematically review research trends, methods, variables, and analytical tools used in studies examining the influence of product quality on consumer purchasing decisions. A Systematic Literature Review (SLR) was conducted on 40 articles published between 2019 and 2024. The results show that product quality and price are the most frequently used variables in previous studies. Most of the research applied a quantitative approach, with SPSS and linear regression being the dominant analytical tools. In addition, research trends over the past five years indicate a shift toward exploring contextual variables such as social media, risk perception, and sustainability preferences. These findings provide valuable insights for researchers and business practitioners to design marketing strategies that align with evolving consumer behavior and product quality expectations.
