ABSTRACT
Aripin, 2020 "Analysis of the occurrence of a cooling water leak in the combustion
chamber of the main engine MV. Spil Hana ”thesis of Engineering Study
Program, Diploma IV Program, Semarang Shipping Polytechnic, Advisor I:
Nasri, M.T, M.Mar.E and Advisor II: Sri Suyanti, S.S.
The main engine is the main driving machine on the ship which becomes the driving /
driving of the ship so that the ship can go forward or backward according to operation.
The entry of cooling water into the combustion chamber affects the performance of the
main engine. The problem is known when going to test the engine before the ship
maneuvers, the main engine is blown up and cooling water comes out of the cylinder
indicator valve no. 1 main engine.
The purpose of this study was to determine what factors caused cooling water to enter
the combustion chamber of the main engine and determine what efforts were made to
overcome the entry of cooling water into the combustion chamber of the main engine.
The author summarizes the problems and tries to identify the problem using the fishbone
analysis.
There are many reasons for the entry of cooling water into the combustion chamber
cylinder engine No. 1 on the MV.Spil Hana ship. The main cause of the entry of cooling
water into the combustion chamber cylinder No. 1 in the MV. Spil Hana is a cylinder
head wall crack, due to incompatible maintenance with PMS and cooling water quality
that affects the cooling system which causes fatigue of the cylinder head and cylinder
head material which has cracks which affects the performance of the main engine. To
deal with these problems based on research by the author, efforts can be made to care and
replace spare parts in accordance with PMS and maintain the quality of cooling water for
a better cooling system

Upaya Hukum Terhadap Rumah Susun yang Tidak Memenuhi Persyaratan Teknis dalam Sertfikat Laik Fungsi
No full textThe scarcity of land has prompted a shift towards vertical housing solutions, with apartments gaining prominence as a viable alternative to traditional single-family dwellings. However, In creating a suitable apartment development, the apartment developer should pay attention to the requirements for the apartment, one of which is contained in the form of Sertifikat Laik Fungsi (SLF) based on Law No. 20 of 2011. SLF essentially functions in providing legality for the operation of an apartment and providing a sense of security. However, in fact there are still flats that have SLF, but they do not comply with the actual condition of the building's reliability, causing losses to the flat's occupants. One of them occurred at the PH Flats. For this reason, the author is interested in studying legal violations regarding SLF ownership by the PH Flats along with the legal measures that can be taken by the residents of the flats due to the losses they suffer. This research is based on normative research methods as well as statutory and conceptual approaches with data sources and types of primary legal materials. The results of this research indicate that legal violations regarding SLF ownership are caused by mal administrative actions by Dinas Cipta Karya dan Tata ruang in issuing SLF along with violations of building reliability requirements carried out by apartment developers. There are legal remedies that can be taken by apartment residents, both in litigation and non-litigation efforts.
