Abstract

Data is a collection generated from various media used by humans. DNA data is a form of data, which is data in the form of genetic code text to store biological identities and characteristics of living things. This study used DNA to test the similarity level of North Sulawesi pigs. The method used is the Pairwise Sequence Alignment method. With sequences of different DNA lengths, the researcher implemented the Needleman-Wunsch algorithm for alignment. Matching is used using the BioPython module, which is in pairwise2. And this study produces a model and proportion of the similarity level of North Sulawesi Pigs that can be used as future references for biological research on molecular biology or for the field of informatics in implementing Needleman-Wunsch algorithm in Python, or references and additional knowledge for research in Bioinformatics.

Abstract

The development of Tomohon City as a tourism hub in North Sulawesi has accelerated significantly, triggering a surge in economic activities and consequently increasing the demand for electrical energy. This study aims to analyze the relationship between economic growth and electricity consumption in Tomohon City, identifying the implications for energy infrastructure planning. A descriptive survey method was employed, using secondary data sourced from the Central Statistics Agency and PT PLN. Data on electricity supply and economic indicators such as Gross Regional Domestic Product (GRDP) were presented in tables, graphs, and diagrams to illustrate growth patterns from 2010 to 2021. Findings reveal that both electricity consumption and installed capacity have increased steadily, with electricity sales rising from 38.4 GWh in 2014 to 48.3 GWh in 2020 and customer numbers increasing from 24,575 to 29,770 over five years. Economic indicators such as GRDP also showed consistent growth, particularly in the tourism, trade, and accommodation sectors. The average annual growth in electricity production was 4.68%, highlighting the need for proactive energy planning. The study concludes that the economic development of Tomohon City is positively correlated with rising electricity demands. It recommends that stakeholders, including PT PLN and local government bodies, develop anticipatory infrastructure strategies to ensure sustainable energy supply, particularly as tourism continues to expand. This research provides critical insight into aligning energy provision with regional economic development priorities.

Abstract

This study analyzes student evaluations of lecturer performance at the Faculty of Engineering, Manado State University, integrating quantitative and qualitative approaches. A total of 127 students from various study programs assessed four main dimensions of lecturer performance: pedagogical, professional, personality, and social competence. Quantitative results indicate that all dimensions received high average scores, indicating that students perceive lecturer performance to be in the good to excellent category. Qualitative findings reinforce these results and reveal aspects that students appreciate, such as clarity of material delivery, professionalism, communicative interactions, and academic exemplary behavior. However, students highlighted the need for increased innovation in more applicable learning methods, broader use of digital media, and more intensive and constructive evaluation feedback. This study confirms that lecturer performance is a strategic factor in improving the quality of engineering learning and provides recommendations for strengthening engineering pedagogy, digitizing learning, and developing a formative evaluation system within a sustainable quality assurance framework.

Abstract

This study aims to develop and test the performance of energy-efficient stoves fueled by used oil as a renewable alternative energy solution for small-scale farmers. The stoves are designed to reduce dependence on subsidized Liquefied Petroleum Gas (LPG) while utilizing the increasing amount of oil waste in rural areas. The method used is Research and Development (R&D) with performance testing through the Water Boiling Test (WBT) and Fuel Consumption Rate (FCR) calculations. The main findings show that used oil stoves have an average thermal efficiency of 32.28%, meeting the SNI 7926:2013 standard (>30%), although slightly below the efficiency of LPG stoves (37.45%). These stoves are able to boil water 3-5 minutes faster than LPG stoves after reaching stable combustion conditions. From an economic perspective, the daily operating cost of used oil stoves is only Rp1,986, or 69.45% cheaper than LPG, and only consumes 4.9% of farmers' monthly income—far lower than LPG, which reaches 16%. With a production cost of IDR 363,000 per unit, this stove is not only affordable but also has the potential to reduce environmental impact through the utilization of waste oil. The research results indicate that used oil stoves are suitable for implementation as appropriate technology that supports energy security and the household economy of farmers.

Abstract

Perkembangan teknologi informasi dan komunikasi (TIK) memberikan peluang bagi perguruan tinggi untuk meningkatkan kualitas pembelajaran, khususnya mata kuliah yang memerlukan simulasi, eksperimen, dan analisis data seperti Mesin Konversi Energi. Artikel ini menganalisis permasalahan implementasi pembelajaran berbasis masalah (Problem-Based Learning/PBL) yang berbasis TIK, terutama terkait pemahaman mahasiswa, keterbatasan infrastruktur digital, pemanfaatan platform online seperti YouTube, dan kesiapan kompetensi dosen. Metode kajian dilakukan melalui studi literatur serta analisis konseptual terhadap implementasi PBL berbasis TIK di pendidikan tinggi. Hasil analisis menunjukkan bahwa penerapan TIK dalam PBL menghadapi hambatan teknis, pedagogis, dan manajerial, sehingga diperlukan penguatan kompetensi mahasiswa dan dosen, perbaikan infrastruktur, dan manajemen pembelajaran yang lebih terstruktur. Artikel ini menawarkan rekomendasi manajerial untuk meningkatkan efektivitas PBL melalui penguatan kapasitas digital, optimalisasi sumber belajar daring, dan pendampingan teknologi.

Abstract

Studi ini bertujuan untuk menganalisis efektivitas pengintegrasian YouTube sebagai media pembelajaran dalam Pembelajaran Berbasis Proyek (PjBL) untuk meningkatkan penguasaan tata bahasa Jepang tematik siswa. Berdasarkan eksperimen yang dilakukan dengan mahasiswa semester tiga, temuan menunjukkan bahwa penggabungan YouTube ke dalam PjBL melalui pembuatan proyek video bahasa Jepang, secara signifikan meningkatkan pemahaman siswa tentang tata bahasa Jepang tematik, dengan skor rata-rata 80,15385. Sementara itu, kelas kontrol yang tidak menggunakan YouTube sebagai media pendukung memperoleh skor rata-rata 80,15385. Penggunaan YouTube ditemukan dapat mengoptimalkan implementasi PjBL, sehingga meningkatkan hasil belajar siswa, tidak hanya dalam tata bahasa tetapi juga dalam keterampilan mendengarkan dan berbicara. Secara keseluruhan, hasil menunjukkan bahwa pengintegrasian YouTube ke dalam PjBL Jepang tematik efektif dalam meningkatkan kemampuan berbahasa Jepang siswa.
