Abstract

Abstrak Penelitian ini adalah Penelitian Tindakan Kelas (PTK) atau Clasroom Action Recearch (CAR) yang bertujuan untuk meningkatan hasil belajar operasi bilangan bulat melalui media domino matematika (DOMIKA. Subjek penelitian ini adalah siswa kelas VIID SMP Negeri 9 Banjarbaru. Penelitian ini dilaksanakan sebanyak 2 siklus dan setiap siklusnya dilaksanakan sebanyak 4 kali pertemuan termaksud tes setiap akhir siklus. Pengambilan data dilaksanakan dengan menggunakan tes hasil belajar siswa pada setiap akhir siklus, dan observasi dilakukan setiap proses pembelajaran berlangsung. Data yang terkumpul dianalisis dengan menggunakan analisis kuantitatif dan analisiss kualitatif. Hasil yang dicapai setelah pelaksanaan tindakan pembelajaran dengan menggunakan media domino matematika (DOMIKA) selama 2 siklus adalah meningkatnya hasil belajar peserta didik. Hal ini dapat dilihat dari skor rata-rata hasil tes yaitu pada siklus I sebesar 69 berada pada kategori tinggi meningkat pada siklus II menjadi 80 berada pada kategori sangat tinggi. Terjadinya peningkatan keaktifan dan aktifitas siswa dalam proses belajar mengajar sesuai dengan lembar observasi yang dilakukan selama penelitian. Kata kunci: Kartu Domino Matematika, Operasi, Bilangan, Hasil Belajar

Abstract

The increasing demand for electrical energy should be supported by efforts to improve the quality of service to customers. The service is said to be unsatisfactory if the electricity supply that is distributed often experiences blackouts which causes customers to be unable to use electricity for a certain period of time. In addition to customers who were harmed due to the non-channeling of electricity, the company's performance value, especially PT. PLN (Persero) ULP Jombang, decreased compared to other ULP. PT. PLN (Persero) ULP Jombang is currently trying to provide the best service by overcoming 20 kV medium voltage power grid disturbances and increasing the company's performance value. PMT disturbance is one of the company's performance values. From a total of 13 feeders in the work area of PT. PLN (Persero) ULP Jombang, PMT disturbances caused by animals occur in the sambong feeder with 2 times the PMT disturbance in 2021. One way to anticipate is not to Repeated PMT disturbances in the sambong feeder, namely by installing zinc climbing barriers at points prone to animals.

Abstract

In the digital transformation era, the demand for automation in household electrical systems continues to grow to improve energy efficiency and user convenience. Traditional manual control of electrical devices is considered inefficient and lacks integration with current smart technologies. This research addresses the problem by designing a smart electrical control system, SmartElectra, which allows users to remotely monitor and control the flow of electricity using an Android-based application. The system integrates the ESP32 microcontroller, a relay module, and a Wi-Fi network to receive and execute commands from the mobile application. The Android interface was developed using MIT App Inventor, enabling seamless wireless communication with the hardware. Testing was conducted to evaluate the system’s responsiveness, control accuracy, and communication range in a typical residential setting. Results show that SmartElectra effectively controls electrical loads with an average response time of 1.2 seconds and reliable operation within a 20-meter range. With its dual-core processing power and built-in wireless capabilities, the ESP32 provides a robust and scalable foundation for smart home applications. This system presents a cost-effective, user-friendly solution that enhances energy management and remote control in modern households.
