Abstract

Pengendalian korosi adalah aspek yang dianggap penting secara teknis, ekonomis, dan estetika. Inhibitor menjadi salah satu bagian dari pengendalian korosi yang bekerja menekan laju  korosi dengan meminimalisir reaksi logam dengan lingkungan. Penggunaan inhibitor dianggap mudah dan efektif pada pengaplikasian pada area tertentu (in situ). Green Inhibitor merupakan inhibitor yang dapat terurai secara biologis, tidak mengandung logam berat, biasanya di hasilkan dari ekstrak tanaman dan buah buahan. Jambu biji merah (Psidium Guajava) merupakan tanaman yang memiliki populasi dan produksi yang besar dimana sampah daun kering yang dihasilkan belum dimanfaatkan optimal. Daun jambu biji merah memiliki kandungan tannin yang memiliki kemampuan sebagai inhibitor korosi. Larutan inhibitor hasil ekstraksi daun jambu biji merah dengan metode maserasi dengan menggunakan pelarut air dilakukan dan dibandingkan dengan ekstrak daun jambu merah pabrikan yang dilarutkan dalam air untuk menguji kemampuan inhibisinya dalam media korosif asam maupun garam. Dilaporkan penambahan ekstrak daun jambu biji merah menurunkan laju korosi pada baja ASME SA36 baik melalui proses ekstraksi dengan menggunakan maserasi menggunakan pelarut aquades maupun menggunakan ekstrak pabrikan yang dilarutkan dalam air, pada kedua media korosif. Larutan inhibitor hasil ekstrasi dengan metode maserasi menggunakan pelarut air efektif menghambat laju korosi 27% pada media korosi air laut, sedangkan untuk media korosif HCl penambahan ekstrak pabrikan yang dilarutkan dalam air efektif menghambat 55% korosi.

Abstract

Waste is an unused or disposed material from a source of human activity and natural processes. So far, waste is still a big problem, because there is no proper solution that causes adverse impact on the environment and health. Less of knowledge about waste processing makes people less concerned about the impact caused. All of the time, waste processingby Landfill method where the waste is transported to landfill (TPA) or taken by scavengers and the rest burned or dumped for a long time. The solution is not an appropriate alternative, because landfills are unsustainable and cause environmental problems. Waste that should be an additional income even burned and impacted for health and the environment. With the garbage bank and the principle of 4R (Reduce, Reuse, Recycle, Replace) for solution of waste, it will help the society to make use of waste into additional income.Thatis one of the steps to awaken the public about the awareness of the surrounding environment and create a clean and economical environment.Keywords: waste, waste solution, garbage bank, 4R, Reduce, Reuse, Recycle, Replace

Abstract

Construction activities include the stages of construction, operation, maintenance, demolition, and rebuilding of a building. One of the construction activities in Indonesia is the construction of double-track railways. In the double-track railway construction project, there is a small excavator A which often fails. The excavator is used for excavation, land stripping, and embankment work. Failures that occur can disrupt construction implementation and can result in the company experiencing losses. Maintenance activities in the construction company that is the research location have a maintenance schedule, namely every 3 months and every 6 months based on the manual book, without adjusting the condition of the equipment. Therefore, it is necessary to analyze excavator components so that appropriate maintenance is known. RCM II is a maintenance evaluation method so that system components run well and according to the expected function by determining a maintenance action that must be carried out based on the characteristics of machine use so that maintenance activities run optimally. This research uses the RCM II method to determine the maintenance schedule, as well as the FMEA method. The FMEA results show 43 failure modes. RCM II decision worksheet analysis showed that 8 components had scheduled discard task maintenance, 3 components had scheduled restoration task maintenance, and 1 component had scheduled on-condition task maintenance.
