Abstract

Abstrak— Salah satu permasalahan yang sering dihadapi oleh nelayan adalah mengenai penanganan pasca penangkapan. Nelayan mengharapkan ikan yang ditangkap tetap segar sampai di tangan konsumen, sehingga dapat dijual dengan harga jual yang tinggi, tetapi fakta yang ada saat ini ikan hasil tangkapan sering mengalami perubahan baik secara fisik maupun kimia yang kemudian secara bertahap mengarah pada proses pembusukan sehingga mengakibatkan harga jual ikan menjadi berkurang. Tujuan dari penelitian ini adalah untuk merangcang sebuah pendingin ikan tenaga surya yang dapat mempertahankan suhu dengan jangka suhu 0-5°C dan dapat diimplementasikan langsung di nelayan sehingga diharapkan dapat membantu nelayan dalam penanganan ikan pasca penangkapan. Alat ini mempunyai mempunyai kapasitas 35 Kg ikan. Pengujian alat ini dilakukan di desa Pulau Pasaran, Bandar lampung. Pengujian dilakukan selama 3 jam. Dari hasil pengujian didapatkan alat pendigin dapat mempertahankan suhu 0-5°C sesuai dengan standar. dan berdasarkan perhitungan alat ini dapat hidup selama 7,9 jam. Kata Kunci : Nelayan, Ikan, Pendingin, Panel Surya Intisari— One of the problems frequently faced by fisherman is about post-catched fish handling. Fishermen expect to have fresh fishes delivered for consumers in the market places to get high selling price when they are sold. However, the current fact is that the fishes are commonly found to be physically and chemically changed and then gradually, the quality is going low due to the loss of preservation which causes the selling price of the fishes decreases. This research aims to design a solar powered fish chiller system that can maintain the temperature in a range of 0°C until 5°C and be able to be implemented for fisherman directly, so that can help them in handling fish after catching. The instrument has a capacity in the amount of 35 kilograms fish. It is tested in a village of Pasaran Island, Bandar Lampung. The testing periode that was carried out is 3 hours. The analysis of the data concludes the chiller system can maintain the standard temperature between 0°C and 5°C and exxtrapolation of the analysis states that the system can be active in 7,9 hours. Keywords : Fisherman, fish, chiller, solar panel

Abstract

Intisari — Penelitian ini akan menyajikan sebuah studi komprehensif tentang kinerja dan perilaku protokol perutean AODV dan DSDV dengan menggunakan standar Wi-fi Direct. Wi-fi Direct  sendiri merupakan standar jaringan nirkabel baru yang memiliki potensi yang cukup unggul  karena bisa digunakan sebagai alternatif untuk menggantikan standar DSRC di VANET. Untuk melihat unjuk kerja dari Wi-fi Direct maka akan dilakukan pengujian pada dua skenario perutean yang berbeda. Kedua skenario pengujian ini akan disimulasikan dengan model mobilitas yang sebenarnya yang ada di wilayah Kota Bandung melalui bantuan simulator NS-2 dan SUMO. Berdasarkan hasil simulasi yang didapat, protokol perutean AODV menghasilkan nilai QoS yang lebih optimal dibandingkan protokol perutean DSDV. Secara keseluruhan, unjuk kerja yang dihasilkan oleh standar Wi-fi Direct dan protokol perutean AODV layak dijadikan alternatif pengganti standar DSRC guna menghasilkan biaya implementasi yang lebih murah. Kata kunci — AODV, DSDV, VANET, DSRC, Wi-Fi Direct, QoS       Abstract — This research will present a comprehensive study on the performance and behavior of AODV and DSDV routing protocols by using Wi-Fi Direct standard. DSRC is a well-known technology being considered as the most promising wireless standard in VANET. The potential of Wi-Fi Direct technology should be concerned because it can be an alternative to replace DSRC in VANET. Performance of Wi-fi Direct will be tested in two different routing scenarios. They will be simulated with a realistic mobility model in Bandung City to analyze the performance by using simulator NS-2 and SUMO. Based on simulation results, AODV routing protocol produces better QoS than DSDV routing protocol for Wi-fi Direct . Overall, the performance generated by the Wi-fi Direct standard and the AODV routing protocol deserve alternative to the DSRC standard in order to realize cheaper implementation costs. Keywords — AODV, DSDV, VANET, DSRC, Wi-Fi Direct, QoS

Abstract

Abstract – The use of lights in daily activities is needed by humans, especially at night. However, when power failure, it will be a problem because the lights will also die. Therefore, in need of an alternative power source other than the PLN to replace the electric source of the lamp when the power off. To overcome this the authors use the battery as a replacement source of electrical voltage from the PLN which at the same time can be refilled automatically when the PLN electric current is on.keywords -- Index terms- Lamp, Emergency, Battery, Power
