Abstract

Mikrokontroler merupakan alat sistem kendali perangkat elektronika yang dibangun untuk dapat mematikan dan menghidupkan perangkat elektronika. Arduino merupakan salah satu mikrontroler yang mudah diaplikasikan untuk sistem kendali teknologi sederhana, seperti: keran otomatis, sistem kontrol rumah, sistem pengaman cerdas dan lain-lain. Langkah-langkah proses pembuatan meliputi: perancangan sistem, pemilihan sensor dan aktuator, sistem otomasi, desain kontrol, pembuatan perangkat keras dan pembuatan perangkat lunak. Kegiatan pengabdian masyarakat ini bertujuan untuk memberikan pengetahuan dasar dan peningkatan keterampilan tentang pembuatan karya teknologi sederhana menggunakan mikrokontroler Arduino kepada siswa Sekolah Menengah Atas (SMA) Al-Husna, Bandar Lampung. Selain itu, kegiatan pengabdian ini juga diharapkan dapat menjadi salah satu sarana peningkatan pemahaman dan kesadaran masyarakat terhadap Jurusan Teknik Mesin, Fakultas Teknik (FT) Universitas Lampung (Unila). Hasil free test dan post test menunjukkan bahwa pengetahuan peserta meningkat secara signifikan untuk semua materi yang disampaikan. Jumlah peserta mengerti yang awalnya hanya berkisar antara 27-30% setelah diberikan materi menjadi meningkat drastis hingga kisaran jumlah peserta yang mengerti mencapai 90%. Dengan adanya hasil yang positif tersebut, diharapkan kegiatan diseminasi teknologi maju oleh Dosen FT Unila dari berbagai jurusan diharapkan dapat ditingkatkan lagi di masa yang akan datang.

Abstract

This study aims to examine the influence of intelligence quotient (IQ) and learning styles on students’ learning motivation and mathematics achievement among tenth-grade high school students. The research employed a quantitative approach using an ex post facto design. A total of 83 students participated in the study, selected through a census sampling technique, as the entire population of tenth-grade students was included. Instruments used in this study included an IQ test, a learning style questionnaire (covering auditory, visual, and kinesthetic styles), a motivation questionnaire, and a mathematics achievement test. Data analysis involved instrument validity and reliability testing, classical assumption tests (normality and homogeneity), and multivariate analysis (MANOVA) to assess both the direct and interaction effects of IQ and learning styles on learning motivation and mathematics achievement. The results showed that IQ had a significant effect on mathematics achievement (p < 0.05), but no significant effect on learning motivation. Learning styles did not significantly influence either mathematics achievement or learning motivation. Furthermore, there was no significant interaction between IQ and learning styles in relation to either outcome. The coefficient of determination (R²) indicated that the model explained 26.3% of the variance in mathematics achievement and 16.5% of the variance in learning motivation. It can be concluded that IQ contributes to students’ success in mathematics, while learning motivation and performance are also shaped by other factors beyond IQ and learning styles. These findings highlight the importance of instructional strategies that consider students’ intellectual capacities along with affective and contextual factors

Abstract

Hospitals, as public service institutions, have a responsibility to integrate environmental aspects into their managerial practices. This study analyzes the influence of green accounting and environmental performance on managerial performance at Rumah Sakit Mata Undaan Surabaya. Data were collected from 39 managerial-level respondents and analyzed using the Structural Equation Modeling-Partial Least Square (SEM-PLS) method with the help of SmartPLS 4.0 software. The results show that green accounting has a positive and significant effect on managerial performance, supporting the stakeholder theory perspective. In contrast, environmental performance has a negative but insignificant effect on managerial performance. These findings highlight the importance of strengthening sustainability strategies in hospital managerial decision-making to create long-term sustainable value.

Abstract

Penelitian ini bertujuan untuk mengevaluasi pengaruh proses torefaksi pada wood pellet berbahan limbah furniture campuran terhadap nilai kalor dan sifat kimia sampel. Sampel wood pellet terdiri dari 80% kayu keras (Meranti, Merbau, Ulin, Mahoni, Keruing) dan 20% kayu lunak (Sengon, Pinus), diproses melalui torefaksi pada temperatur 250°C, 275°C, dan 300°C selama 30 menit. Pengujian nilai kalor dilakukan untuk menentukan peningkatan energi, dan analisis proximate serta ultimate dilakukan untuk mengetahui perubahan sifat kimia. Hasil menunjukkan bahwa nilai kalor meningkat secara signifikan setelah proses torefaksi, dengan peningkatan tertinggi pada temperatur 300°C mencapai 5.161 kkal/kg atau naik sekitar 32,3% dibandingkan nilai kalor awal 3.902 kkal/kg. Uji proximate menunjukkan peningkatan kandungan karbon tetap dan abu, serta penurunan kadar air dan zat volatil. Uji ultimate menunjukkan peningkatan kadar karbon hingga 60,19% dan penurunan kadar oksigen hingga 26,61% pada temperatur 300°C. Selain itu, torefaksi meningkatkan sifat hidrofobik wood pellet, terbukti dari ketahanan terhadap perendaman air yang lebih tinggi. Berdasarkan hasil ini, dapat disimpulkan bahwa torefaksi pada temperatur tinggi (300°C) secara efektif meningkatkan kualitas energi dan kestabilan wood pellet, menjadikannya alternatif bahan bakar biomassa yang lebih efisien dan tahan terhadap kelembapan.

Abstract

Growing environmental degradation has become a pressing global issue, highlighting the importance of education in shaping the environmental awareness of the younger generation. This study aims to fill the gap in the literature regarding the contribution of schools in building sustainable learning ecosystems that promote environmental awareness among students. This study uses a qualitative method with a case study approach in several schools that implement environmental education programs. Data were obtained through in-depth interviews with principals, teachers, and students, observation of school activities, and document analysis of environment-related education policies. The results showed that the integration of environmental issues in the curriculum, the implementation of nature-based extracurricular programs, and the management of environmentally friendly school facilities play a significant role in building students' awareness of sustainability. Activities such as reforestation, waste management and environmental campaigns allow students to be directly involved in sustainability practices, which in turn increases their understanding of and responsibility for environmental conservation. The involvement of various stakeholders, including families and communities, to support the creation of an effective learning ecosystem. This research provides strategic recommendations for policy makers to design a more integrated and impactful environmental education program. This research is expected to serve as a guide in efforts to strengthen environmental awareness through an educational approach

Abstract

The Instrument Landing System (ILS) is a critical component of aviation navigation that ensures aircraft landing accuracy and safety. However, public understanding of restricted ILS areas and equipment placement criteria remains limited, as existing informational media—such as regulatory documents or slide presentations—lack interactivity and spatial visualization. This study aims to design and evaluate a Virtual Tour-based ILS Application as an interactive educational medium to visualize and explain the placement criteria of ILS equipment in a three-dimensional (3D) environment. The research used the ADDIE (Analysis, Design, Development, Implementation, Evaluation) instructional design model to systematically develop the application. The content and functional design were derived from the Indonesian Civil Aviation Authority’s SKEP/113/VI/2002 and ICAO Annex 10 Volume I standards. Data collection methods included observation, expert validation, and user testing. The application was evaluated using three quality dimensions of the ISO 25010 software standard: functional suitability, compatibility, and usability. Participants included media experts, subject matter experts, and 20 community members residing near Budiarto Airport, Indonesia. As a result, the Virtual ILS application achieved high evaluation scores across all dimensions—functional suitability (97.5%), compatibility (100%), and usability (90.16%)—indicating excellent performance, ease of use, and educational value. The interactive 3D visualization effectively improved users’ comprehension of ILS restricted zones and equipment placement requirements, compared to conventional informational media.
