Abstract

Pesticide sprayer tools that are widely used by farmers are still using hands or fossil fuel machines, so they are still classified as traditional and ineffective methods. Some of the weaknesses of the traditional method include less practical, fossil fuels that will run out and the impact on the environment. Solar energy from the sun can be a solution to these problems. Solar panels are devices used to convert sunlight into electrical energy. In this study, a monocrystalline 30W solar panel was used as a tool used to capture sunlight. By utilizing solar power as an energy source sprayer and pump so that it can take advantage of the hand pressing the lever and refilling it manually. In addition, preferring solar power over fossil fuel engines can reduce the use of fossil fuels and further strengthen renewable energy that will not run out and is environmentally friendly. In this study, solar panels were installed above the head to maximize the capture of sunlight and also protect the head from the heat of the sun. The results showed that the battery energy required to spray the difference in battery percentage from 10 liters to 6 liters of liquid volume was 4% and from 6 liters to 2 liters of liquid volume was 6%.

Abstract

COP on a cooling machine is used to reveal the performance of a cooling engine. To increase the COP value in the system, it can be done by changing the dimensions of the filter-drier and capillary pipes used. Therefore, this study was conducted to determine the effect of changing the dimensions of the filter-drier and capillary pipe on the COP and the consumption of electrical power produced by the 2-door refrigerator unit. The method used was an experimental method, namely by varying the filter drier and capillary tube dimensions of the 2-door refrigerator. Variations of filter driers used were filter driers with sizes 7 cm and 9 cm. While the capillary pipes used were 0.31 inches in diameter and 0.51 inches in diameter with a length of 200 cm and 250 cm respectively. The results obtained from this study indicate that the greatest COP value is obtained when using a 7 cm filter-drier and a capillary pipe with a diameter of 0.31 inches with a length of 200 cm, which is 2.80. The COP value also continues to decline as the size of the filter-drier and capillary pipes used increases.

Abstract

In this study, Fuzzy-Fractional Order Proportional Integral Derivative (Fuzzy-FOPID) control technique is applied to regulate the speed of a separately excited DC motor. This control technique uses a combination of two intelligent algorithm tuning methods, Fuzzy logic and Genetic Algorithm (GA). This is done to get an effective and powerful control effect. The identification of parameters in the form of Kp, Ki and Kd uses fuzzy logic and for fractional parameters in the form of μ and λ using GA. To find out the performance of this control technique several tests have been carried out using the MATLAB 2013a simulation which then the results are compared with Fractional-Order PID (FOPID) control technique where all parameters are obtained using GA tuning. In testing the speed and constant load the performance of the Fuzzy-FOPID control has a smaller overshoot value and the settling time is faster than the FOPID control. The FOPID driver has a better undershoot response of 0,25% when there is a change in the added load. But when testing the speed change, Fuzzy-FOPID control has a fast and stable response with an undershoot value of 0.875% and a 0.143% overshoot, smaller than the FOPID control. From the results of all tests, it can be concluded that Fuzzy-FOPID control is better and more efficient than FOPID control.Dalam penelitian ini, teknik kendali Fuzzy-Fractional Order Proportional-Integral-Derivative (Fuzzy-FOPID) diterapkan untuk mengatur kecepatan motor DC penguat terpisah. Teknik kendali ini menggunakan gabungan dua metode penalaan algoritma cerdas yaitu logika fuzzy dan Algoritma Genetika (GA). Hal ini dilakukan untuk mendapatkan efek kendali yang efektif dan kuat. Penalaan  parameter Kp, Ki, dan Kd menggunakan logika fuzzy dan untuk parameter fractional μ dan λ menggunakan GA. Untuk mengetahui kinerja dari teknik kendali ini telah dilakukan beberapa tes menggunakan simulasi MATLAB 2013a yang kemudian hasilnya dibandingkan dengan teknik kendali lain yaitu teknik kendali FOPID dimana semua parameternya didapat dengan menggunakan penalaan GA. Pada pengujian kecepatan dan beban konstan performa kendali Fuzzy-FOPID memiliki nilai overshoot yang lebih kecil dan settling time lebih cepat dibanding kendali FOPID. Pengendali FOPID memiliki respon undershoot yang lebih baik sebesar 0,25 % ketika tejadi  penambahan  beban. Namun ketika dilakukan pengujian perubahan kecepatan, kendali Fuzzy-FOPID memiliki respon yang cepat stabil dengan nilai undershoot 0,875 % dan overshoot 0,143%, lebih kecil dibandingkan dengan kendali FOPID. Dari hasil seluruh pengujian dapat disimpulkan bahwa kendali Fuzzy-FOPID lebih baik dan effisien dibandingkan dengan kendali FOPID.

Abstract

Gardu induk adalah komponen penting dalam sistem distribusi energi listrik yang berperan sebagai penghubung utama untuk mengalirkan listrik dari pembangkit ke konsumen. Secara khusus, fungsi utama dari gardu induk adalah untuk melakukan transformasi daya listrik sehingga dapat disalurkan secara efektif dan efisien. Petir dapat merusak peralatan tegangan tinggi di jaringan distribusi. Tegangan tinggi dari sambaran petir dapat menyebabkan flashover jika isolasi tidak cukup baik. Di Indonesia, yang merupakan negara tropis, kerapatan petir cukup tinggi, yaitu antara 5 hingga 15 sambaran per kilometer setiap tahun. Lightning arrester adalah perangkat yang awalnya berfungsi sebagai isolator, namun saat terkena petir, ia menjadi konduktor dengan resistansi rendah untuk mengalirkan arus ke tanah. Arrester sangat penting untuk melindungi peralatan listrik dari bahaya tegangan lebih, terutama yang disebabkan oleh petir. Keberhasilan perlindungan peralatan listrik tergantung pada pemilihan, pemasangan, dan perawatan lightning arrester yang tepat.Tujuan dari peneltian ini adalah untuk mengetahui dan menganalisis kinerja arrester berdasrkan arus bocor dan suhu body arrester yang dihasilkan terhadap pemilihan 2 bahan yang berbeda yaitu porselen dan polimer. Analisis dilakukan dengan pengambilan data langsung di PT. PLN (Persero) UPT Purwokerto GISTET 500 kV Adipala.Hasil penelitian perhitungan arus bocor Hasil analisis selama empat tahun terakhir menunjukkan adanya perbedaan nilai arus bocor antara arrester porselen dan arrester polimer dalam merespon sambaran arus petir. Dari data ini, dapat dilihat bahwa suhu pada body arrester polimer lebih stabil dan cenderung lebih rendah dibandingkan dengan arrester porselen.

Abstract

Abstrak Krisis lingkungan dan iklim global menuntut pendidikan untuk turut serta dalam solusi melalui pendekatan Greening Education, sebagaimana diinisiasi oleh UNESCO. SMK Negeri 1 Puring yang memiliki visi ramah lingkungan menjadi mitra dalam kegiatan pengabdian masyarakat bertajuk Greening Education 101, yang bertujuan meningkatkan kompetensi civitas akademika dalam aspek pengetahuan, keterampilan, sikap, dan nilai konservasi lingkungan. Kegiatan menggunakan pendekatan manajerial POAC (Planning, Organizing, Actuating, Controlling) yang diterapkan pada seluruh tahapan pelaksanaan. Metode pelatihan terdiri atas ceramah, tanya jawab, demonstrasi, praktik mandiri, dan pendampingan. Evaluasi dilakukan melalui pretest-posttest. Pelatihan diikuti oleh 24 peserta pada tanggal 11 Juni 2025 dan menghasilkan peningkatan signifikan pada seluruh aspek. Pengetahuan meningkat dari 38% menjadi 88%; keterampilan dari 25% ke 56%; sikap dari 88% ke 100%; dan nilai konservasi dari 44% ke 81%. Hal ini menunjukkan efektivitas pelatihan dalam menginternalisasi prinsip greening education. Namun, pelaksanaan hanya satu hari menjadi kendala dalam pendalaman materi dan pengukuran outcome jangka panjang. Partisipasi peserta juga bervariasi, dengan dominasi komunikasi satu arah. Pelatihan Greening Education 101 efektif dalam meningkatkan kompetensi peserta di bidang pendidikan berkelanjutan. Diperlukan pelatihan lanjutan berdurasi lebih panjang dan pendekatan komunikasi dua arah untuk mendukung transformasi lingkungan sekolah secara menyeluruh. Kata kunci: greening education; pendidikan lingkungan; SMK; sustainable development. Abstract The global environmental and climate crisis demands that education participate in solutions through the Greening Education approach, as initiated by UNESCO. SMK Negeri 1 Puring, with its environmentally friendly vision, became a partner in a community service activity entitled Greening Education 101, which aims to improve the competence of the academic community in the aspects of knowledge, skills, attitudes, and values of environmental conservation. The activity uses the POAC (Planning, Organizing, Actuating, Controlling) managerial approach, which is applied at all stages of implementation. The training includes lectures, questions and answers, demonstrations, independent practice, and mentoring. Evaluation was carried out quantitatively and qualitatively through pretests and posttests. Twenty-four participants attended the training and significantly improved all aspects. Knowledge increased from 38% to 88%; skills from 25% to 56%; attitudes from 88% to 100%; and conservation values from 44% to 81%. This demonstrates the effectiveness of the training in internalizing the principles of greening education. However, the one-day implementation hampered in-depth understanding of the material and the measurement of long-term outcomes. Participant participation also varied, with one-way communication predominating. The Greening Education 101 training effectively improved participants' competencies in sustainable education. Further, longer training and a two-way communication approach are needed to support comprehensive school environmental transformation. Keywords: environmental education; greening education; sustainable development; vocational high schools.
