Abstract

There are still many dumpling cracker makers who are generally done at home as a small home industry where they still use human labor to make the dough so that it takes a lot of energy and a long time, the use of human labor causes a lack of time efficiency and the possibility of decreased hygiene. Seeing these problems, the community service team of the D3 Engineering study program at the Maritime University of Amni Seamarang provided solutions to these problems by designing tools and providing training in the operation of the dough mixer to accelerate the production process and increase the hygienic value of production. The result of this service is a double stirring of the dumpling cracker dough which increases the speed of the kneading production process for 30 minutes / dough.

Abstract

In addition to knowing the various types of machining components that exist, operators are required to know the maintenance and be able to measure each component so that the diesel engine's performance does not experience problems that result in decreased engine performance. Meanwhile, the supporting components of the diesel engine are like cylinder liners, because the cylinder liner components determine the volume of the cylinder and the performance of the diesel engine. The shape of the cylinder liner is like a tube where the manufacturing process uses a horizontal centrifugal casting process. Horizontal Centrifugal casting process is a casting process for making cylinder liners by pouring molten metal into a rotating mold. Implementation of Top Overhaul on diesel engines is carried out by opening the cylinder head or the top of the engine. The parts examined include the rocker arm, inlet and exhaust valves, injectors, air starting valves and push rods. Top Overhaul is carried out when the working hours of the diesel engine have worked with around 6,000 hours of work. Major Overhaul maintenance, which includes inspection, maintenance and inspection carried out on all Top Overhaul works and on the piston, connecting rod, piston ring, seated metal and road metal. Major Overhaul maintenance is carried out when the diesel engine has 12,000 working hours according to the Diesel Engine Intruction Book. In the cylinder liner often occurs damage or looseness which is commonly referred to as abrasion, erosion and corrosion. Because of that the cylinder liner requires maintenance and measurement using an inside micrometer tool. From the results of the measurements and maintenance on the cylinder liner, the calculation of the consistency, taper and wear was obtained, to find out the specifications or exceed the limits specified in the Main Engine Intruction Book on the ship.

Abstract

Penelitian ini dilatar belakangi oleh pentingnya pencegahan terhadap pencemaran air laut yang berasal dari pembuangan limbah air dari kamar mesin kapal. Oil water separator merupakan salah satu peralatan yang dapat digunakan untuk mencegahan pencemaran yang berasal dari kamar mesin. Apabila minyak kotor yang bercampur dengan air laut dibuang melalui OWS, maka minyak kotor yang berasal dari limbah air got kamar mesinsetelah melewati OWS maka limbah air got yang dibuang ke laut sudah aman bagi lingkungan karena kandungan campuran minyak dan kadar minyak tidak melebihi dari 15 PPM. Tujuan dari penelitian ini adalah untuk mengetahui manajemen perawatan dan perbaikan OWS untuk mencegah terjadinya pencemaran di laut pada KM. Lawit. Metode penelitian yang digunakan adalah pendekatan kualitatif karena untuk menggambarkan bagaimana manajemen perawatan OWS untuk mencegah terjadinya pencemaran di laut pada KM. Lawit secara lebih rinci dan jelas sedangkan. Hasil dari penelitian ini adalah untuk melakukan perawatan pada OWS di KM. Lawit perlu dilakukannya manajemen perawatan yang meliputi perencanaan, pengorganisasian, pelaksanaan serta yang terakhir pengawasan pada saat mengoperasikan OWS.
