Abstract

This study is motivated by the increasing complexity of corporate crime, which necessitates the reform of criminal law policy in Indonesia, particularly through Law Number 1 of 2023 on the Criminal Code. The research questions focus on how criminal policy toward corporations is formulated under the new Criminal Code and how effective its implementation is in addressing corporate crime. This research employs a normative legal method using statutory and conceptual approaches, supported by a literature review of primary and secondary legal sources published within the last five years.The findings indicate that the 2023 Criminal Code formally recognizes corporations as subjects of criminal law and adopts a flexible liability framework through a combination of identification theory, vicarious liability, and strict liability, while also providing a broader range of sanctions. However, the effectiveness of this policy remains constrained by challenges in proving corporate fault, potential sentencing disparities, and limited institutional capacity of law enforcement agencies.This study recommends the development of clear technical guidelines for corporate criminal liability, strengthening institutional capacity, and integrating penal and non-penal approaches through the implementation of good corporate governance principles.

Abstract

This study aims to analyze the effectiveness of penal and non-penal policies in combating terrorism in Indonesia and to identify juridical and criminological challenges in their implementation. The study is grounded in the evolving dynamics of terrorism, particularly reflected in the case of Jamaah Ansharut Daulah (JAD), which demonstrates that weakening organizational structures does not necessarily eliminate radical ideology. This research employs a normative legal method using statutory, conceptual, and case approaches. The findings reveal that penal policies under Law Number 5 of 2018 are effective in law enforcement and prevention of terrorist attacks but have not addressed the ideological roots of radicalization. Meanwhile, non-penal approaches, particularly deradicalization programs, face limitations in preventing recidivism and ensuring sustainable social reintegration. The main challenges include ambiguous legal norms, potential human rights violations, and complex criminological factors such as ideology, social networks, and digital transformation. This study highlights the necessity of integrating penal and non-penal strategies based on human rights principles, emphasizing preventive and rehabilitative approaches to achieve a more effective and sustainable counter-terrorism framework.

Abstract

In the World of Information Technology computer science, data security something that is very important so that data can not be misused by some parties who have not / not have rights. In the delivery of documents documents is needed a security so that the document file can be accepted by those who have the right to receive it. It is therefore very necessary to process a document encryption / encryption file. Among the science of cryptography that can secure the document file such as LSB Steganography Algorithm (Least Significant Bit). This analysis aims to improve the security of document files by encoding a document file, then providing a password into the document file.Keywords : Encryption, Data Security, LSB Steganography, Files, Documents

Abstract

Lithium demand increases as it is widely used as raw material for rechargeable battery, alloy for airplane, andfuel for fusion nuclear reactor. Lithium is an extremely reactive element, that it is never found as free element innature. Lithium compounds are found in earth crust, with very small concentration (20 – 70 ppm) and totalcontent of more than 20 million tons. The biggest lithium reserve is in seawater (0,14 – 0,25 ppm) andgeothermal water (7 ppm) with total amount of 230 billion tons. There is no industry applies the technology torecover lithium from seawater. Having a vast sea area and abundant geothermal sources, Indonesia needs todevelop a technology to recover lithium from both sources. This research is aimed to recover lithium fromgeothermal water. The experiment was conducted using synthetic and geothermal water with lithiumconcentration range of 220 – 400 ppm, temperature range of 20 – 40°C, and mixing time range of 1 – 4 hours.The experiment was designed with 2 level factorial design. The results show that the most influencing variable ismixing time, while significant interaction amongst variables is not observed. Further experiment usinggeothermal water from Bledug Kuwu with initial lithium concentration of 400 ppm and temperature 30°Cresulted in optimum mixing time, i.e. 3 hours with 92,5% of the lithium could be recovered

Abstract

One of the most dangerous pollutants in wastewater is ammonia. The concentration of ammonia inwastewater discharged from nitrogen fertilizer industry is up to 1500 ppm. Ammonia can be removed byseveral methods such as biological denitrification, air-stripping, and ion exchange. The methods cannotreduce the concentration of ammonia to a low level as required for standard quality of wastewater. Theelectrochemical method has recently attracted attention for the treatment of wastewater containing ammonia.This research is aimed to evaluate the effect of ammonia concentration, current density, and time on theelectrolysis process. Synthetic wastewater containing 500-1500 ppm of ammonia was used in this research.The solution was electrolyzed in a electrolytic cell with Pt/SS electrodes. The experiment was conducted byvarying current density in the range of 5 – 10 mA/cm2 and time from 0 to 105 minutes. The experiment resultsshow that as current density rises, the electrolytic reaction occurs more rapidly. On the other hand, initialconcentration of ammonia has negative effect on the final conversion of ammonia.
