Abstract

Tujuan dari penelitian ini adalah untuk mengetahui hubungan antara media pembelajaran berupa alat peraga jangka sorong dan metode pembelajaran games terhadap motivasi belajar dan hasil belajar siswa kelas X TPM 2 SMKN 1 Singosari. Metode yang digunakan pada penelitian ini menggunakan metode tindakan kelas yang terdiri dari dua siklus yaitu siklus I dan siklus II. Jenis penelitian ini menggunakan metode analisis data deskriptif kuantitatif dan deskriptif kualitatif. Subjek penelitian ini adalah siswa SMK Negeri 1 Singosari jurusan Teknik Pemesinan kelas X yang berjumlah 35 siswa. Hasil penelitian menunjukkan bahwa media pembelajaran berupa alat peraga jangka sorong dan metode pembelajaran games pada pembelajaran dasar-dasar teknik mesin materi pengukuran dinyatakan berpengaruh terhadap peningkatan motivasi belajar dan keberhasilan belajar peserta didik. Pelaksanaan pembelajaran pada siklus 1 dan siklus 2 menghasilkan peningkatan pada nilai minimal peserta didik, nilai peserta didik dengan predikat baik dan sangat baik, dan rata-rata nilai kelas jika dibandingkan dengan tahap pra siklus. Dari pembelajaran siklus 1 menunjukkan peningkatan dan kemajuan yang cukup baik namun masih ada siswa yang mendapat nilai dibawah 70 sehingga perlu untuk dilakukan siklus selanjutnya. Dari pembelajaran siklus 2 diperoleh hasil belajar dengan semua indikator keberhasilan tercapai sehingga dapat dikatakan cukup dalam pelaksanaan tindakan kelas.

Abstract

This study focuses on the design and implementation of an electrical system for a bread dough proofer tool, specifically optimized for donut dough fermentation, utilizing a microcontroller with Proportional-Integral-Derivative (PID) control. The proofing process is crucial for dough quality, and maintaining precise temperature and humidity conditions is essential for consistent results. The PID control algorithm continuously calculates the error between desired setpoints and measured process variables, adjusting actuator outputs to minimize this error. The PID parameters were tuned using a trial-and-error method to achieve optimal response speed and stability, with values of , , and . Experimental results demonstrate the system’s effectiveness in stabilizing the proofing environment. The temperature was maintained at 40.10  with a minimal overshoot of 0.30  and a rise time of 10.25 minutes. Humidity was regulated within the range of 80-90% RH for 38.4 minutes, with a rise time of 40.41 minutes. The system exhibited robust disturbance rejection, quickly recovering from external perturbations. Compared to manual proofing, the automated system reduced proofing time by approximately 25% and significantly improved donut dough quality, evidenced by enhanced volume expansion and uniform texture.   Keywords - Bread Dough Proofer, PID Control, Microcontroller, Temperature and Humidity Control, Automated Proofing System

Abstract

The plastic injection moulding process is a dominant manufacturing method for producing high-precision components. Final product quality is highly dependent on process parameters, particularly injection time and injection pressure. This study aims to quantitatively analyze the influence of these parameters on product weight and quality, specifically in mitigating common defects such as shrinkage and short shots. Utilizing polypropylene material, a factorial experimental design was implemented by varying injection time 3,5 s, 4 s, 4,5 s and pressure 36 bar, 37 bar, 38 bar. Each parameter combination was replicated five times to ensure data validity. Product weight was measured using a digital scale, and visual quality was manually evaluated. The findings indicate that increases in injection time and pressure significantly enhanced product weight and reduced defects. An optimal combination of a 4 s injection time and 37 bar pressure was identified, yielding products with consistent weight and superior visual quality. These results offer practical guidance for optimizing production processes and improving efficiency. Keywords: Injection Moulding, Injection Time, Injection Pressure, Product Quality.

Abstract

The limited availability of interactive teaching aids hinders students from understanding renewable energy concepts in depth. This community service study aimed to improve energy literacy among 60 high school students (30 per school) at Almaarif Islamic High School Singosari and Diponegoro Islamic High School Wagir using the Solar Energy Kit as an educational medium. A participatory, learning-by-doing method was employed, encompassing interactive lectures, tool demonstrations, and hands-on assembly practice in small groups. Students assembled photovoltaic systems and measured electrical output under varying sunlight conditions using a built-in multimeter. Pre- and post-test results showed an average knowledge gain of 40.6%, and questionnaire responses indicated a significant increase in students' interest in eco-friendly technology and environmental awareness. The Solar Energy Kit is an effective and practical teaching medium that is recommended for integration into the school science curriculum.
