Abstract

Laboratorium merupakan sebuah sarana yang mendukung pembelajaran khususnya IPA, namun beberapa sekolah yang berada di daerah belum memiliki peralatan laboratorium yang memadahi, salah satunya adalah SMP Pusaka yang berada kecamatan Ciranjang. Pengukuran adalah salah satu materi dari pelajaran IPA, dalam melakukan pengukuran diperlukan alat ukur. Alat ukur yang sering diujikan di ujian nasional adalah jangka sorong, micrometer skrup dan multitester, tetapi alat ukur ini tidak tersedia di SMP Pusaka. Program Studi Pendidikan Fisika Universitas Kristen Indonesia melakukan pengabdian kepada masyarakat ke SMP Pusaka dengan melakukan kegiatan pelatihan penggunaan alat laboratorium berupa alat ukur jangka sorong, mikrometer skrup dan multitester serta menyumbangkan alat-alat tersebut. Pelatihan dilaksanakan kepada siswa kelas 7 SMP sejumlah 29 siswa, setelah pemaparan tim melakukan pendampingan kepada siswa untuk melakukan pengukuran dan mengisi lembar kerja yang telah disediakan, kemudian diberikan kuesioner untuk mengetahui pemahaman siswa dan kesan kepada instruktur. Dari hasil kuesioner yang dijawab oleh siswa menyatakan bahwa materi pelatihan mudah dipahami, diaplikasikan dan menambah pengetahuan, secara keseluruhan materi yang diajarkan mendapatkan respon baik dengan presentase rata-rata 86,6 %. Menurut kesan para siswa pelatih dari Pendidikan Fisika UKI memberikan perhatian, pendampingan dan penyajian materi yang baik dengan persentase rata-rata 85,4 %.

Abstract

One of the implementation of advances in information and communication technology that can be used for online exam is the iSpring Quiz Maker. This research aims to: (1) determine the feasibility of iSpring Quiz Maker as the online exam tool of physics worklab; (2) determine the student interest responses in using iSpring Quiz Maker as the online exam tool of physics worklab; as well as (3) determine the effectiveness of iSpring Quiz Maker as the online exam tool of physics worklab. The method of this research is research and development (R & D) by applying the ADDIE (analysis stage, design stage, development stage, implementation stage and evaluation stage) model. The results showed that: (1) iSpring Quiz Maker is very feasible as physics worklab online exam tool based on the assessment of both material and media expert validators; (2) Students are very interested in using iSpring Quiz Maker as physics worklab online exam tool; and (3) iSpring Quiz Maker has not been effective as physics worklab online exam tool because the percentage of the total students who got score of 50 is 77.6% while the percentage of the total students who got score > 50 is 22.4%.

Abstract

Accurate evaluation of head losses is essential in industrial systems transporting viscous chemical fluids, such as sodium hydroxide (NaOH), to ensure hydraulic efficiency and operational reliability, particularly in chlor alkali plants. This study analyses major and minor flow losses in the NaOH piping system at PT X Chlor Alkali Plant, Porsea, and evaluates the pipe design's hydraulic feasibility. After defining system parameters—including fluid properties, pipe geometry, and the number and type of fittings—technical calculations were conducted to assess flow profiles and pressure losses along two main pipe routes. A quantitative analysis using the Moody diagram and operational data reveals that minor losses dominate, contributing over 75% of total head loss in both routes. The total head loss remains within the pump's rated capacity (18 m), though with a narrow margin. A pipe diameter of 0.114 m produces a flow velocity of 0.79 m/s, aligning with recommended industrial standards for corrosive fluids. The use of Sch.80 stainless steel proves effective in minimizing frictional losses, particularly under turbulent flow conditions. These findings highlight the critical role of fitting configurations and material selection in optimizing chemical process piping systems.
