Aktivitas penambangan yang dilakukan dengan cara peledakan yang kemudian diangkut menggunakan Dump Truck untuk dikirim ke unit Crushing plant agar diproses sesuai ukuran. Pengolahan granodiorit di unit Crushing plant terdiri dari dua tahap yaitu Primary crushing dan Secondary crushing. Alat yang digunakan yaitu 1 unit primary crushing (Jaw Crusher) dan 1 unit Secondary crushing (Cone Crusher). Penggunaan alat Crushing tersebut didukung oleh alat penunjang seperti Hopper, feeder, screening dan belt conveyor. Rangkaian pengolahan tersebut menghasilkan produksi berupa abu batu, 1x1 mm, 1x2 mm, dan 0,5 mm. Adapun tujuan dari kegiatan ini adalah mengevaluasi ketercapaian target produksi granodiorit di PT. TOP dan mengetahui faktor-faktor yang menghambat kinerja alat crushing plant..Hasil evaluasi produksi pada belt conveyor 11,12,13, dan 14 telah sesuai dengan target produksi di PT. TOP, namun target produksi tersebut belum optimal. Untuk itu perusahaan dapat meningkatkan target produksi tanpa perlu menambah alat belt conveyor pada unit Crushing plant. sedangkan faktor yang menghambat kinerja crushing plant adalah lambatnya penanganan terhadap mesin crushing plant yang rusak, ukuran material terlalu besar.","PeriodicalId":394289,"journal":{"name":"Journal of Applied Mechanical Engineering and Renewable Energy","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133875229","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}

During the period 2018-2020 the BELL 412 EP helicopters often experienced unscheduled maintenance which resulted in losses resulting in flight failure, this was due to a malfunction in the Main Rotor Blade system. The malfunction of the Main Rotor Blade system is dominated by the hub component, namely on the shaft associated with Crack, Noise and Burn damage, and blade components, namely Corrosions, Nicks, Scratches, Dents, Deformation Holes and Crack. Therefore, the aim of this study is to eliminate failure system and unscheduled maintenance. \u0000To eliminate failure and unscheduled maintenance, the authors perform an analysis with the FMEA method and calculate using the distribution method, then design the appropriate activities on the system. The data used for analysis are qualitative and quantitative data, where the authors use data from Time To Failure (TTF) and Time To Repair (TTR). \u0000According to calculations using the current distribution we found that the Main Rotor Blade system was on time during the 200 operational flight hours, for which the reliability figure was 0.70. Maintenance activities in accordance with the operational conditions of the main rotor blade operating system are preventive maintenance with activities for tool preparation, inspection or chek, dismantling and servicing, and finally installation and finishing activities.","PeriodicalId":394289,"journal":{"name":"Journal of Applied Mechanical Engineering and Renewable Energy","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134000083","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 use of metals that have good hardness is very necessary, especially in the engine parts which must always be in contact with other engine parts. One way to increase metal hardness is to add carbon to the metal. The process of adding carbon is by solid carburizing. The use of calcium carbonate catalyst can also be used to accelerate the reaction of the solid carburizing. This study aims to determine the effect of the carburizing process on ST 37 steel either by using a catalyst or without a catalyst to the hardness test. From the results of observations and data collection that has been done, the average hardness value of raw material is 47.9 HRB. For ST 37 steels which are heat treated at 900ºC, normalizing process and quenching process have an average hardness value of 47.5 HRB and 49.05 HRB. As well as ST 37 steel which is carried out by a solid carburizing process using catalysts and without catalyst, each has a hardness rate of 48.6 HRB and 48.2 HRB. From the results above it is known that the cooling time affects the hardness of steel ST 37. The carburizing process can increase the hardness due to the addition of carbon to the steel. Catalysts play a role in increasing the hardness of steel, this is because the catalyst can accelerate the rate of reaction in carburizing","PeriodicalId":394289,"journal":{"name":"Journal of Applied Mechanical Engineering and Renewable Energy","volume":"94 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-02-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115792073","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}

Salah satu cara mengatasi hal tersebut adalah dengan proses offload. Peralatan yang penting untuk kegiatan offload adalah pompa offload. Pompa ini digunakan untuk memindahkan cairan yang telah ditampung di vessel ke trunkline. Unjuk kerja pompa offload dalam memtransfer cairan merupkan hal yang sangat penting. Penelitian ini bertujuan melihat perubahan unjuk kerja pompa offloading antara kondisi awal sesuai spesifikasi pabrik dengan saat ini setelah dipakai selama ± 9 tahun. Jenis pompa yang diuji adalah pompa multistage sentrifugal model 20 WUC-2R-19. Pengujian performansi pompa offload dilakukan dengan menvariasikan bukaan katup discharge sebesar 25%, 50%, 75% dan 100%. Kemudian membandingkan performansi pompa aktual dengan data terkoreksi menggunakan hukum affinity law. Pengujian ini tidak memperhitungkan perubahan karakteristik cairan yang terjadi saat kegiatan offload. Hasil penelitian menunjukan telah terjadi penurunan performansi antara kondisi awal operasi tahun 2011 dengan kondisi aktual tahun 2020. Kapasitas aktual pompa turun menjadi sebesar 23,45 m3/h dibandingkan kapasitas disain sebesar 24 m3/h. Efisiensi pompa offload menurun dari kondisi awal sebesar 80 % menjadi 7,71%. Penurunan efisiensi selama 9 tahun adalah sebesar 2,29% atau 0,25% per tahun.","PeriodicalId":394289,"journal":{"name":"Journal of Applied Mechanical Engineering and Renewable Energy","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116331842","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}

Variabel penelitian ini meliputi lama perendaman 1 jam, 2 jam, 3 jam, serat yang di gunakan serat tebu dan perbandingan fraksi volum resin dan katalis 65% (2% katalis) dan serat tebu 35%. Spesimen yang digunakan sesuai standar pengujian impak ASTM D 5942-96, dengan metode Charpy. Pada penelitian ini dapat disimpulkan bahwa dari tiga spesimen yang diuji diperoleh spesimen satu (1 jam) mempunyai energi serap terbesar dengan harga impak 0,5374 Joule/mm2. Semakin lama perendaman serat ampas tebu kedalam larutan alkali maka energi terserap semakin kecil.
