Analysis Of Mechanical Properties Of Rubber Fruit Shell Composites Due To Compression Pressure Variations As An Alternative Material For Brake Pads
No full textMotorized vehicles are used to dissipate the vehicle's motion energy so that the vehicle slows down. The working principle of this brake is that there is friction between the disc and the brake pad when these two brake components come into contact. So that with this friction, the kinetic energy coming from the vehicle is converted into heat. Based on this, a solution is needed to handle it by utilizing the potential of rubber fruit shells, as well as increasing the economic value of the waste. Thus, research is needed to make brake pads using composite materials made from rubber fruit shell waste as an alternative material for motorcycle brake pads. Rubber fruit shell composites are made with several loading variations, with variation I: 2 ton loading, variation II: 3 ton loading and variation III: 4 ton loading. In this study, several tests were carried out, namely friction testing, microstructure and hardness testing to get results that are close to conventional motorcycle brake pads on the market. In this conclusion, it can be obtained that the effect of the variation in compaction pressure on the hardness value, wear rate and microstructure of the specimen of the brake pad material of the rubber fruit shell material is greater the pressure of the compaction load, the results obtained are also closer to those on the market. Variation in compression loading in the analysis of mechanical properties of rubber fruit shell composites due to compression pressure variations as an alternative material for motorcycle brake pads that get the maximum value with a hardness value of 28.43 BHN and a wear rate value of with the influence of variations in compaction loading on specimens. This test obtained the highest hardness result at the loading of a 4-ton compaction with a hardness value of 28.43 BHN and the lowest hardness value at a 2-ton loading with a hardness value of 19.90 BHN. Analysis of the mechanical properties of rubber fruit shell composites due to compression pressure variations as an alternative material for motorcycle brake pads obtained the lowest wear rate value with the value of at the loading variation of 2 tons and the result of the highest wear rate valueon the variation of compac tion loading at a load of 4 tons. This test obtained the results that the microstructure in the specimen had a difference in the variation of the loading of the compact, in the loading complex of 2 tons and 3 tons had a non-homogeneous microstructure so that the distribution of powder on the specimen was uneven. In loading, the 4-ton Compaction has a homogeneous microstructure so that the powder is evenly distributed.86 PagesSkripsi Sarjan

Comparative Analysis Single Economic Entity Doctrine in Business Competition Law in Indonesia (Comparative Study with the United States)
No full textSingle Economic Entity Doctrine (SEED) is a doctrine that views several different legal entities as one economic unit from a business competition law perspective. The point of contact between company law and business competition law regarding the implementation of SEED is whether or not the parent company controls its subsidiaries as one inseparable business unit, which affects the subsidiary's independence in determining its market behavior.
This thesis research uses normative juridical methods with a comparative approach to identify how SEED is implemented in Indonesia and the United States. The research results show significant differences in the scope, implementation criteria, and jurisprudence related to SEED. In Indonesia, the application of SEED is still limited and does not yet have clear criteria even though it has been implemented in several KPPU decisions. Meanwhile in the United States, SEED has a strong legal basis through Section 1 Sherman Act and jurisprudence. It is recommended that SEED be adopted explicitly in the revision of Law Number 5 of 1999 or in KPPU regulations taking into account its implementation practices in the United States.139 PagesSkripsi Sarjan

Study of the Influence of Sending TPA Mencirim Activities on the Water Quality of the Mencirim River, East Binjai
No full textThe Mencirim River, which is located in East Binjai District, is one of the water sources that
the community uses for daily activities. The flow from the Mencirim River passes through the
Mencirim Landfill with a distance of ± 50 m from the Mencirim Landfill which is thought to
indicate pollution from leachate contamination originating from the Mencirim Landfill which
causes a decrease in river water quality. The aim of this research is to analyze the quality of
river water and leachate water (temperature, pH, DO, TSS, BOD and COD), and analyze the
level of pollution in Mencirim River water. This research was carried out in 2 sessions, namely
on June 27 2024 and July 18 2024. The method for determining river water quality used in this
research is the Pollution Index method contained in the Decree of the Minister of Environment
Number 115 of 2003 concerning Guidelines for Determining Water Quality Status. Based on
the results of research that has been carried out, there are parameters such as BOD that exceed
class 2 water quality standards in Government Regulation Number 22 of 2021 which are at
downstream of the Mencirim River, and TSS parameters that exceed leachate water quality
standards in the Minister of Environment Regulation Life and Forestry Republic of Indonesia
No. 59 of 2016 concerning Leachate Quality Standards for Final Processing Place Businesses.
Based on the results of calculations using the Pollution Index method, the quality status or level of water pollution ranges from 1.0 ≤ IP ≤ 5.0 and is classified as lightly polluted.97 PagesSkripsi Sarjan
