Abstract

The substance of the Narcotics Act has not provided a clear conception regarding the application of the law to narcotics users who use narcotics for themselves who are qualified as addicts and narcotics victims. As a result, the application of the law against narcotics users, has not yet fully realized legal certainty. dapun problems in this study regarding the application of Article 127 in conjunction with Article 103 of the Narcotics Act? Regarding the obstacles in applying the provisions of Article 127 in conjunction with Article 103 of the Narcotics Act against narcotics abusers? What is the ideal criminal law policy in making effective the implementation of Article 127 in conjunction with Article 103 of the Narcotics Act?This type of research is normative juridical research, while the nature of the study is descriptive analysis. This research uses several approaches, namely the law and conceptual approach. The research data consisted of secondary data sources. The data analysis used in this study is qualitative data analysis. Based on the results of the study, the application of Article 127 in conjunction with Article 103 of the Narcotics Act against abusers who use narcotics for themselves does not yet have legal certainty. The substance of the Narcotics Act is still ambiguous. Obstacles in applying the provisions of Article 127 in conjunction with Article 103 of the Narcotics Act, are influenced by three factors, namely the legal substance factor that has not been supported. Legal structure factors, related to the not yet created professionalism of law enforcement officers in law enforcement and legal cultural factors, that is related to community legal awareness. The ideal criminal law policy in streamlining the application of Article 127 in conjunction with Article 103 is to revise the provisions of the Narcotics Act, specifically Article 112 Paragraph (1) of the Narcotics Act by adding the phrase "with the intention of selling or distributing narcotics ...".

Abstract

This study examines the influence of the application of a rotating magnetic field in the electrodeposition of copper (Cu). During the electrodeposition, five constant magnets were rotated (500 and 800 rpm) towards the bottom of the sample. To investigate deposition rate, surface morphology, phase, structure, corrosion resistance, and hardness in deposited Cu using a weighing scale, a scanning electron microscope equipped with energy dispersive spectroscopy (SEM-EDS), X-ray diffraction (XRD), potentiodynamic polarization, and hardness tester respectively. Bacterial activity was also evaluated through this research. Morphological surface observations showed that the increase in the rotational speed of the magnets during the electrodeposition process led to a smooth surface. A perfect Cu phase covers Al alloy with no oxide. The potentiodynamic polarization demonstrated by the increase in the rotating led to a shift to the more positive value of the corrosion potential. Moreover, the corrosion current also decreases with the increase in the rotating speed of the magnets. Less crystallite size promoted forming a higher hardness and inhibition zone of the Cu films.

Abstract

Microstructure modification of the plain carbon steel usually enhances hardness and corrosion resistance. Therefore, in the present research, the microstructure of plain carbon steel is modified by heating it in an electric furnace using various temperatures and then quenching it in engine oil to enhance corrosion resistance and hardness. Several characterizations were conducted, such as microstructure, hardness, and electrochemical behavior. The microstructure evolution indicates a clear transformation of martensite morphology with decreasing austenitizing temperature. Decreasing the furnace's heating before quenching could increase the specimens' hardness and corrosion resistance, with values around 586.36 HV and 0.135 mmpy. Therefore, the optimal heat treatment condition for plain carbon steel components in marine environments was found at 800 °C based on the results of this study.
