This research aims to develop the design of wind-solar power plants in shrimp pond areas. The prototype was developed according to the design of the generator made. Design efficiency is demonstrated by analyzing electrical energy generated in the system. The methods include: build generator system design, prototype assembly and testing. The design developed is to maximize work of the radial generator system through manufacturing of rotors with neodymium magnets. The test results obtained an average battery charging of 29.72 watts. The lowest solar intensity occurs at 06.00 WIB (46300 lumens). While the highest intensity occurred at 14.00 WIB (116200 lumens). The highest wind speed of 2.8 m/s at 12:00 WIB. This clarifies that the intensity of the sun and wind speed affect the value of battery, the value will be directly proportional that the greater the intensity and speed, the greater electrical energy produced.

Abstract: Magnetoimpedance (MI) effect was observed on multilayer samples [Ni80Fe20(800)nm)/Cu(x)nm]4 Cu-Printed Circuit Board substrates. The multilayer system was grown through an electrodeposition process by modifying thickness of the Cu layer. The MI effect was analyzed by means of an impedance test under an external magnetic field at low frequency 100 kHz. The results found that MI ratio increased ± 1.02 fold with the reduction Cu layer (800 nm until 0 nm) from 2.39% to 3.44%. This condition is believed by differences resistance of magnetic layer to conductive layer in the multilayers system. The measured sample resistance value is inversely proportional to the function of “x” as the thickness of the conductive layer. This means that the reduction conductive layer can be improve magnetic properties for a multilayer [Nife/Cu]N system. The analysis calculation of the sensitivity value also shows the potential increase sample sensitivity to 0.9746% / mT.Abstrak: Magnetoimpedansi (MI) telah diamati untuk sampel multilapisan [Ni80Fe20(800)nm)/Cu(x)nm]4 substrat Cu-Printed Circuit Board. Sistem multilapisan ditumbuhkan melalui proses elektrodeposisi dengan memodifikasi ketebalan lapisan Cu. Efek MI dianalisis melalui pengujian impedansi dibawah medan magnet luar pada frekuensi 100 kHz. Hasil uji ditemukan rasio MI meningkat ±1.02 kali lipat dengan berkurangnya lapisan Cu (800 nm sampai 0 nm) dari 2,39 % menjadi 3,44 %. Kondisi ini diyakini oleh adanya perbedaan resistensi lapisan magnetik dengan lapisan konduktif pada sistem multilapisan. Nilai resistensi sampel yang terukur berbanding terbalik terhadap fungsi x sebagai ketebalan lapisan konduktif. Artinya berkurangnya lapisan konduktif dapat meningkatkan sifat magnetik sampel untuk sistem multilapisan [Nife/Cu]N. Analisa perhitungan nilai sensitifitas juga menunjukan potensi kenaikan sensitifitas sampel tertinggi sampai 0,9746 %/mT.

Magnetoimpedansi (MI) telah diamati untuk sampel multilapisan [Ni80Fe20/Cu]N substrat Cu-Printed Circuit Board. Sistem multilapisan ditumbuhkan melalui proses elektrodeposisi dengan memodifikasi jumlah perulangan multilapisan sebanyak N = 2 sampai 6. Rasio MI dianalisis melalui pengujian impedansi dibawah medan magnet luar pada frekuensi 100 kHz. Jika diaplikasikan sebagai sensor magnet, nilai sensitifitas dapat dianalisa menggunakan persamaan ξ = 2[(∆Z/Z)max]/∆H. Hasil uji dan perhitungan ditemukan keselarasan antara peningkatan rasio magnetoimpedansi dengan sensitifitas sensor berbanding lurus. Rasio MI meningkat ± 1.61 kali lipat dengan penambahan jumlah multilapisan [Ni80Fe20/Cu]N dari N = 2 sampai N = 6 lapis, atau meningkat dari 3.32 % menjadi 5.36 % sebesar 2,04 %. Peningkatan tersebut kemungkinan disebabkan karena bertambahnya jumlah multilapisan pada sampel meningkatkan permeabilitas bahan magnetik sistem multilapisan itu sendiri. Penambahan jumlah multilapisan telah meningkatkan sensitifitas sensor sebesar ±1,64 kali lipat. Sensitifitas tertinggi didapat pada sampel dengan N=6 sebesar 0,61 %/Oe.

The addition of Ni metal dopants to the ZnO photocatalyst material has been carried out using the immersion method followed by sonication. The variables observed included variations in the concentration of addition of Ni and sonication time. The results of the optical absorption analysis from the uv-vis test showed that the optimum condition was reached at a concentration of 25% Ni and a sonication time of 30 minutes. The optical absorption peak has shifted towards the wavelength of visible light and new absorption peaks have been observed in the wavelength range of 425-450 nm and 650-750 nm. The energy band gap also decreased from 3.22 eV to 3.09 eV. While the crystal size analysis of the XRD diffraction pattern showed a decrease in the crystal size at 25%Ni from 105.012nm to 78.545nm.

Desa Margasari memiliki potensi wilayah pesisir dengan sumber energi angin, matahari, dan limbah cangkang kerang yang belum termanfaatkan secara optimal untuk mendukung perekonomian masyarakat setempat. Program pengabdian masyarakat di Desa ini bertujuan untuk mendukung sektor ekonomi masyarakat melalui kegiatan penyusunan layout desain teknologi tepat guna berbasis energi terbarukan. Kegiatan penyusunan layout teknologi ini meliputi pembuatan desain sistem teknologi pengeringan ikan berbasis energi matahari, desain turbin angin Venturi untuk solusi kebutuhan energi listrik, dan pembuatan panduan/metode pengolahan limbah cangkang kerang sebagai bahan tambahan pembuatan paving block. Metode pengabdian yang digunakan meliputi: koordinasi, pemetaan kebutuhan, penyusunan layout teknologi, dan presentasi kepada peserta (perangkat desa, masyarakat, dan pelaku usaha tepung ikan). Presentasi difokuskan pada pengenalan desain dan tahapan konstruksi yang dapat dirancang agar dapat diadopsi masyarakat secara mandiri. Layout teknologi tepat guna dirancang untuk memberikan panduan yang jelas, meliputi prosedur konstruksi bertahap dan spesifikasi teknis, sehingga memungkinkan penerapan yang praktis di kemudian hari dan sesuai dengan keperluan lokal masyarakat. Layout teknologi ini juga diharapkan akan memicu realisasi inovasi teknologi berbasis sumber daya lokal yang dapat diterapkan di wilayah Desa margasai serta wilayah-wilayah pesisir lainya.
