Charger handphone adalah alat yang dimiliki oleh hampir setiap orang. Jika terjadi kerusakan maka masyarakat cenderung akan membuangnya dan membeli yang baru. Tapi di sisi lain charger yang rusak terse-but akan menambah limbah elektronik. Charger tersebut dapat dimanfaatkan kembali dengan cara memper-baikinya. Oleh karena itu penelitian ini bertujuan untuk menganalisis jenis-jenis kerusakan pada charger handphone kemudian mengganti komponen yang diindikasikan rusak dengan komponen baru. Terdapat tiga tahap pengolahan sinyal pada charger handphone. Tahap pertama adalah penyearahan sumber alternating current (AC) dari PLN menjadi sumber direct current (DC). Pada tahap ini komponen yang digunakan berupa dioda dan kapasitor. Tahap kedua adalah tahap pensaklaran (switching), dihasilkan tegangan AC dengan frekuensi tinggi (orde kilohertz). Pada tahap ini komponen yang digunakan pada charger non-smartphone adalah transistor, kapasitor dan resistor, selain itu digunakan optocoupler untuk menjaga tegangan output 5V tetap stabil. Sedangkan untuk charger smartphone digunakan IC daya tanpa menggunakan optocoupler. Tahap ketiga adalah menurunkah amplitudo sinyal AC kemudian dirubah ke bentuk DC. Pada tahap ini digunakan transformer, dioda dan kapasitor. Berdasarkan enam belas charger rusak yang berhasil dikumpul-kan (enam charger non-smartphone, sepuluh charger smartphone), lima dari enam charger non-smartphone mengalami kerusakan pada optocoupler, sedangkan pada charger smartphone lima dari sepuluh sampel men-galami kerusakan pada kabel USB. Dua mengalami kerusakan pada kapasitor, dua mengalami kerusakan pa-da dioda dan satu sampel sisanya mengalami kerusakan pada fuse (sekring). Digunakan multimeter digital untuk mengecek kerusakan komponen tersebut, diagnosa kerusakan tersebut valid karena setelah komponen yang dianggap rusak diganti dengan yang baru, charger berfungsi normal.

RANCANGAN ALAT INDIKATOR LEVEL TEGANGAN BATERAI BERBASIS OPERATIONAL AMPLIFIER (OP AMP) Muh Pauzan
TEKNOKOM Vol. 2 No. 1 (2019): TEKNOKOM
Publisher : Department of Computer Engineering, Universitas Wiralodra

Telah dilakukan rancangan alat indikator level tegangan dengan memanfaatkan operational amplifier (op amp) sebagai komparator. Alat yang dibuat digunakan untuk mengetahui level tegangan dua baterai Li-Ion 3.7V yang disusun seri. Tegangan habis (end voltage) untuk dua baterai adalah 6 V dan tegangan maksimumnya 8.4 V. Tapi pada alat yang dibuat ditentukan 8 V sebagai tegangan maksimum. Terdapat empat indikator, pertama indikator LED merah untuk 25% (6.5V) tegangan baterai, LED kuning untuk 50% (7V), LED hijau untuk 75% (7.5V) dan LED biru untuk 100% (8V) tegangan baterai. LED akan menyala jika output op amp adalah high. Output high terjadi jika tegangan masuk Vin yang melalui pin 2 lebih besar daripada tegangan referensi ref pada pin 3 op amp.Dilakukan perhitungan secara teoritis kemudian dibuat rangkaiannya menggunakan softwareProteus.

The school bell is one of the important devices in school. It has been used from years ago to the present. Bell has been improved along with time. Nowadays, research about school bell has been focused on the bell’s controller, such as using software in a computer, placing a keypad on the bell, and even controlling the bell’s schedule, which can only be performed using coding. However, these controllers are not practical; therefore, an efficient school bell is made by using an Android-based application as the controller. Bluetooth is used as a communication tool between the smartphone and the bell. The research method was by conducting a literature study and doing a survey to SDN 1 Sarapati Indramayu. Based on the method, it has been decided to make four modes on the Android application, i.e., regular mode, exam mode, free, dan emergency mode. Regular mode is used in a normal condition, and exam mode is used when the students are doing an exam. If teachers want to ring the bell directly, the free mode is operated. There are four types of bell ring in free mode, i.e., once, twice, three, and four-time rings. Emergency mode is useful when the school is in an emergency, such as earthquakes, floods, and fires. Results show that the maximum range to control the bell is 9 m.

Pola yang ada pada jari bersifat unik, pola tersebut dinamakan biometrik. Biometrik digunakan pada metode absensi fingerprint. Penelitian tentang absensi dengan fingerprint baru sebatas pengolahan data absensi tanpa dibuat alat fingerprintnya yang layak pakai. Oleh karena itu dibuat alat absensi dengan metode fingerprint berbasis Arduino yang lebih baik. Jika penelitian-penelitian sebelumnya menggunakan database dan EEPROM di mikrokontroler untuk penyimpanan data absensinya, pada penelitian ini micro SD digunakan untuk penyimpanan data. Tahapan penelitian dimulai dari studi literatur, kemudian perancangan perangkat keras, lalu perancangan perangkat lunak. Setelah alat jadi, dilakukan ujicoba pada alat untuk menganalisis performanya. Dilibatkan 30 responden, masing-masing melakukan scan ibu jari dan telunjuk. Berdasarkan uji jumlah percobaan, ibu jari dan telunjuk memiliki rata-rata jumlah percobaan 1,70 dan 2,73 berturut-turut. Pada uji waktu respon, telunjuk lebih baik dengan waktu rata-rata 2,39 detik berbanding 2,79 detik untuk ibu jari. Pengguna sebaiknya melakukan scan minimal selama 2 detik supaya dapat dideteksi alat.

Formalin is a hazardous chemical substance that has a pungent odor, is colorless or clear, and is flammable. It should be used to preserve corpses, but often misused by unscrupulous traders to preserve food. Formalin has harmful effects on the human body if it is ingested. Therefore, a practical tool that can detect the presence of formaldehyde in food is needed. Making a formalin detection tool using the Mamdani fuzzy inference system is very useful for detecting formalin and the level of food safety quickly and economically. This tool used the HCHO and the MQ-7 sensors combined with an expert system, namely fuzzy logic. The HCHO detects formalin in the food, like the sense of smell; meanwhile, the MQ-7 sensor detects carbon monoxide (CO). In the testing process, a heater was utilized to vaporize the food samples. The vapor was then detected by the two gas sensors and was processed using the fuzzy logic of the Mamdani method. To see the test’s accuracy using the tool, its results were compared with those of the formalin kit and the Fuzzy Logic Toolbox in MATLAB. The results showed that the lowest level of formalin in the tofu sample, namely sample H, was 0.60 ppm; meanwhile, the highest level was in sample E, with 13.64 ppm. The lowest formalin found in salted fish, namely sample P, was 7.14 ppm, while the highest formaldehyde level was in the salted fish sample, namely sample T, with 193.81 ppm. Compared with the formalin kit results, the accuracy value obtained from the total testing of twenty samples was 95%. The output of the tool was nearly identical to that of MATLAB: 85% with a difference of 0.01 and 15% with a difference of 0.02. The average error between tool output and MATLAB was 0.77%.

Massive Open Online Courses (MOOCs) have emerged as powerful tools that bridge vast learning resources with diverse global learners, particularly gaining prominence during and after the COVID-19 pandemic. While numerous studies have investigated the general application of MOOCs, limited research has specifically focused on their distribution and utilization within the field of mathematics education, especially in the post-pandemic context. This study aims to fill that gap by conducting a systematic literature review on MOOCs in mathematics, using the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) framework to ensure a rigorous and replicable review process. At the identification stage, 2,349,886 articles were initially retrieved. After a comprehensive screening process based on inclusion and exclusion criteria, 78,191 articles were considered relevant. From this pool, 12 articles specifically addressed MOOCs in mathematics. However, only 6 articles met all the eligibility criteria for in-depth analysis. The findings reveal several key insights: (1) mathematics MOOCs are underrepresented in research, particularly in the context of school education; (2) research output on mathematics MOOCs has declined post-pandemic; (3) quantitative research methods dominate the field, limiting deeper qualitative insights; and (4) African countries remain significantly underrepresented in terms of both production and study of MOOCs in mathematics. This study contributes novel insights to the literature by highlighting geographic and methodological research gaps. It suggests that future research should explore mathematics MOOCs in school contexts, particularly using mixed-method approaches, and focus on understudied regions like Africa to promote equitable digital education access and innovation.
