Abstract

Sistem pengapian pada motor bakar merupakan prasyarat untuk terjadinya pembakaran dan juga menentukan kualitas dari proses pembakaran tersebut. Persyaratan utama dari sistem pengapian adalah mampu menyuplai energi panas yang dibutuhkan dalam bentuk percikan bunga api listrik busi pada volume yang kecil dan waktu yang cukup untuk terjadinya pembakaran. Berbagai jenis sistem pengapian dikembangkan untuk berbagai keperluan dan hasil yang berbeda sesuai dengan kebutuhan. Metode penelitian yang digunakan adalah metode eksperimental. Objek penelitian ini adalah mengukur kadar kandungan karbon monoksida (CO) gas buang yang dihasilkan oleh sepeda motor 4 langkah 110ccdengan sistem pengapian CDI dengan sumber arus AC (CDI-AC) dan sumber arus DC (CDI-DC) yang diuji dalam berbagai putaran mesin (RPM) yang berbeda. Dari hasil penelitian didapatkan nilai rata-rata kandungan CO gas buang yang dihasilkan pada sistem pengapian CDI-AC adalah sebesar 6,91%, sedangkan rata-rata pada sistem pengapian CDI-DC adalah 7,07%. Berdasarkan temuan ini persentase rata- rata kandungan CO pada gas buang sistem pengapian CDI-DC lebih tinggi dibandingkan persentase rata-rata CDI-AC, namun fluktuasi kadar CO pada sistem CDI-DC lebih kecil dibandingkan CDI-AC pada berbagai RPM yang berbeda. Hal ini sesuai dengan karakteristik sistem pengapian CDI-DC yang menghasilkan tegangan lebih stabil sehingga gas CO yang dihasilkan dari pembakaran juga lebih stabil dibandingkan sistem pengapian CDI AC.

Abstract

The main component of the injection system is the electronic control unit (ECU) functions to optimize the performance of the vehicle engine. The ECU has the functions of injection duration and ignition time as an injector and ignition controller. The purpose of the study analyzed the comparison and differences in variations in the regulation of injection duration and ignition time of injection motor engines against the power output of the engine using pertamax fuel by experimental methods. There are comparisons and differences in power and torque in each variation of the programmable ECU and standard ECU settings. The highest average power and torque results at the standard ECU setting compared to the programmable ECU setting have lower average power and torque. Due to the different injection duration and ignition time of each setting, the power and torque generated by the motorcycle engine can be higher or lower per variation of the Programmable ECU setting. In addition to the difference in power output and engine torque, it also has differences in SFC values and the average Thermis Efficiency produced varies by variation of the programmable ECU settings.

Abstract

Abstract Teachers' success is a critical measure of educational accomplishment; however they lack the ability to create appropriate assessment instruments. This community service program aims to improve teachers' high-order thinking skill assessment tool development. The goal is to empower teachers to develop 21st-century skills. This service uses observation, teacher competency mapping, training, and evaluation. Traditional teaching approaches include lectures, discussions, and assignments. After the classical learning period, the teachers discuss and assigns work using Google Classroom for about a week. The activities took place in West Java's SMPN 1 Mande and SMAN 1 Muara Gembong. 21 Mande District teachers and 13 Muara Gembong District teachers completed Google classroom exercises and assignments. The activity showed proficiency in using the HOTS-based evaluation tool. Before the training session, 27.0% of teachers were knowledgeable with the HOTS-based evaluation technique. This training program improved teachers' ability to construct assessment instruments associated with Higher Order Thinking Skills (HOTS) by 19%. In addition, participants learn how to develop multiple-choice assessment instruments that use higher-order thinking skills (HOTS). Abstrak Keberhasilan guru adalah ukuran penting dari pencapaian pendidikan; Namun, mereka tidak memiliki kemampuan untuk membuat instrumen penilaian yang tepat. Program pengabdian masyarakat ini bertujuan untuk meningkatkan pengembangan alat penilaian keterampilan berpikir tingkat tinggi guru. Tujuannya adalah untuk memberdayakan guru untuk mengembangkan keterampilan abad ke-21. Layanan ini menggunakan observasi, pemetaan kompetensi guru, pelatihan, dan evaluasi. Pendekatan pengajaran tradisional meliputi ceramah, diskusi, dan tugas. Setelah masa pembelajaran klasik, para guru mendiskusikan dan menugaskan tugas menggunakan Google Classroom selama sekitar satu minggu. Kegiatan berlangsung di SMPN 1 Mande Jawa Barat dan SMAN 1 Muara Gembong. 21 guru Distrik Mande dan 13 guru Distrik Muara Gembong menyelesaikan latihan dan tugas kelas Google. Kegiatan tersebut menunjukkan kemahiran dalam menggunakan alat evaluasi berbasis HOTS. Sebelum sesi pelatihan, 27,0% guru memiliki pengetahuan tentang teknik evaluasi berbasis HOTS. Program pelatihan ini meningkatkan kemampuan guru dalam mengkonstruksi instrumen penilaian yang terkait dengan Higher Order Thinking Skills (HOTS) sebesar 19%. Selain itu, peserta belajar bagaimana mengembangkan instrumen penilaian pilihan ganda yang menggunakan keterampilan berpikir tingkat tinggi (HOTS).

Abstract

The Merdeka Belajar curriculum represents a significant shift in Indonesia's educational landscape, emphasizing freedom in learning and the development of critical thinking and practical skills. Vocational High Schools (SMKs) play a crucial role in preparing students for the workforce, and effective industry partnerships are essential for achieving the curriculum’s goals. Despite their importance, there is a lack of innovative models that facilitate these partnerships effectively. This study aims to explore and propose innovative models for SMK-industry partnerships that align with the Merdeka Belajar curriculum. By identifying and evaluating these models, the study seeks to enhance the quality of vocational education and better prepare students for employment. The research employs a mixed-methods approach, combining qualitative and quantitative data collection techniques. Surveys and interviews with key stakeholders, including educators, industry partners, and policymakers, were conducted to gather insights. Additionally, case studies of successful SMK-industry partnerships were analyzed to identify best practices. The data were then synthesized to develop and evaluate innovative partnership models. Results of the study identify three innovative models for SMK-industry partnerships: Model A, which focuses on co-designed curriculum development; Model B, which emphasizes dual apprenticeship programs; and Model C, which integrates real-world projects into the learning process. Each model was evaluated based on criteria such as effectiveness, scalability, and sustainability. The findings indicate that these models significantly enhance student engagement, skill acquisition, and employability.

Abstract

Kebutuhan air bersih di wilayah perkotaan semakin meningkat seiring dengan laju urbanisasi dan pertumbuhan penduduk yang pesat. Masjid sebagai pusat aktivitas umat Islam menghasilkan volume air wudhu yang besar setiap harinya. Penelitian ini bertujuan untuk mengembangkan model pemberdayaan masyarakat melalui penguatan kompetensi dalam pengelolaan air, khususnya dengan memanfaatkan air wudhu menjadi air siap minum, sehingga mendukung keberlanjutan fungsi masjid di kawasan perkotaan. Metode yang digunakan meliputi survei lapangan, perancangan teknologi pengolahan air berbasis filtrasi multistage (pasir manganese, karbon aktif, resin, filter cartridge spun, granular active carbon (GAC), membrane RO, dan post carbon), serta pelatihan teknis kepada masyarakat, serta evaluasi keberhasilan melalui peningkatan kompetensi peserta. Hasil kegiatan menunjukkan peningkatan kompetensi masyarakat sebesar 73% berdasarkan evaluasi pre-test dan post-test, serta kualitas air hasil olahan memenuhi standar air minum sesuai Peraturan Menteri Kesehatan Republik Indonesia No. 2 Tahun 2023. Temuan ini menegaskan bahwa program penguatan kompetensi berbasis teknologi pengolahan air mampu mendukung konsep fungsi masijd sebagai pusat pembangunan manusia, serta memperkuat keberlanjutan lingkungan di wilayah Jakarta Utara.
