{"title":"PERAHU NELAYAN MENGGUNAKAN JERIGEN PLASTIK BEKAS UNTUK MENINGKATKAN KESEJAHTERAAN NELAYAN","authors":"Purwo Joko Suranto, Bambang Sudjasta","doi":"10.54378/bt.v14i2.364","DOIUrl":"https://doi.org/10.54378/bt.v14i2.364","url":null,"abstract":"Perahu nelayan adalah suatu sarana yang dapat mengapung di air yang digunakan oleh para nelayan untuk mencari dan menangkap ikan di sungai maupun di laut. Perahu nelayan merupakan sarana yang paling penting bagi para nelayan untuk digunakan mencari dan menangkap ikan, tanpa adanya perahu maka nelayan tidak bisa mencari nafkah untuk keluarganya. Di Indonesia cukup banyak sekali masyarakat perkampungan nelayan, dikarenakan Indonesia merupakan negara kepulauan dimana setiap pulau dikelilingi oleh lautan. Mereka tersebar dan hidup bermukim di daerah-daerah pinggiran pantai atau pesisir pantai di seluruh wilayah kepulauan Indonesia. Mahalnya harga perahu nelayan, sehingga banyak nelayan yang tidak mempunyai perahu sendiri. Kebanyakan mereka bekerja pada juragan-juragan kapal sebagai buruh nelayan, dengan demikian penghasilan mereka tidak mencukupi untuk memenuhi kebutuhan keluarga. Dilain pihak banyak sekali jerigen-jerigen plastik bekas tempat minyak yang tidak dimanfaatkan sehingga bisa menjadi limbah, jerigen-jerigen plastik inilah yang akan dimanfaatkan untuk pembuatan perahu nelayan. Tentunya didesain dan dihitung kekuatan serta stabilitas dari perahu tersebut, sehingga terjamin keselamatan nelayan dalam mencari ikan di laut. Ukuran pokok Perahu yaitu Panjang Perahu Keseluruhan (Loa) = 3,80 m, Panjang Perahu antara Garis Tegak (Lpp) = 3,40 m, Sarat Perahu (T) = 0,400 m, Lebar Kapal (B) = 0,858 m, Kecepatan dirancang = 6 knot. Sesuai dengan besarnya kecepatan perahu 6 knot maka didapat Hambatan Perahu adalah 840,83 Newton (N) serta Besarnya Effektif Horse Power (EHP) perahu tersebut adalah 3,48 Horse Power (HP). Berdasarkan EHP yang didapat maka dapat dicari besarnya Break Horse Power (BHP) perahu tersebut, setelah melalui perhitungan berdasar dari EHP tadi maka didapatkan besarnya BHP mesin adalah  6,931 HP kemudian dicari mesin yang ada dipasaran didapat BHP mesin 7 HP. Besarnya muatan perahu dihitung sesuai displasemen perahu dimana Displasemen = DWT + LWT dimana unsur muatan terdapat pada DWT sehingga setalah melalui perhitungan maka didapat hasil muatan yang bisa diangkut oleh perahu tersebut sebesar 655,5 kg. Stabilitas perahu pada kondisi muatan kosong (Empty Load) sebagaimana maupun pada kondisi muatan penuh (Full Load) menunjukan bahwa stabilitas perahu nelayan tersebut sangat baik artinya apabila perahu oleng atau miring akibat ombak, angin atau muatan maka perahu tersebut dapat kembali keposisi tegak sehingga perahu tidak tenggelam, maka aman digunakan oleh nelayan.","PeriodicalId":441070,"journal":{"name":"Bina Teknika","volume":"196 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114922992","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The Indonesian government represented by PT. PLN (State Electricity Company) will continue to maintain, operate and maintain old hydropower plants. So far, the development and development of PLTMH in Indonesia still uses consultants / contractors and its manufacturing is from overseas, even components (spare parts) are also still dependent on the technology producers themselves, the majority of which are foreign countries. Imports cannot be avoided, this results in us being vulnerable to several things, fluctuations in foreign exchange rates, and dependence on foreign producers. But with the increasing understanding of national resilience, especially in terms of national industrial independence, several national companies began to carry out reconstruction and fabrication for hydroelectric power plants. This is encouraging the author to learn to know, understand, how to plan the main parts of the Kaplan Turbine which include: runner, shaft, spiral casing, stacker, draft tube. In this plan the author focuses on calculating the main dimensions of the Kaplan Turbine. From the results of the design and calculation, the appropriate type of turbine is Kaplan Turbine as an electric generator drive in Plumbungan PLTM with installed power of 1.2 MW, maximum head of 21.16 meters and water discharge requirement of 7.68 m3 / sec. Plumbungan PLTM installation consists of turbines, turbine supporting equipment, and turbine operation aids. The turbine installation component consists of: suction pipe (penstock), turbine house (spiral casing), runner, runner shaft, shaft support bearing and draft tube.","PeriodicalId":441070,"journal":{"name":"Bina Teknika","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123853898","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the examination of the 1000 cc sedan engine that has been operating for 30,000 hours found a rough sound on the engine and experienced loss compression on the cylinder block number 2. The purpose of the study was to obtain the factors causing the deformation of the piston 1000 cc sedan vehicles. The research method used is metallographic observation using ASTM E 3 and ASTM E 112, testing hardness using ASTM E 92 and SNI 19-0409-1989 and testing chemical composition using ASTM A 751. The results of research on piston damage can be seen that observation macrostructure proves that there is plastic deformation on the surface area of the piston material, the results of microstructure observation are known to occur microcrack on the top surface of the right side of the piston, there is no change in micro hardness between the piston material in the deformed area with the deformed piston material hardness, piston material made of alloy Al-Si. In the area of the piston surface that experiences deformation, Mg2Si and Mg2Al3 compounds are formed, these compounds which cause microcrack on the piston's upper surface. Plastic deformation on the piston surface occurs due to a collision between the piston surface and the cylinder head due to the buildup of crust on the piston surface.","PeriodicalId":441070,"journal":{"name":"Bina Teknika","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114638448","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
