Corporations, as legal entities, can be held criminally liable for corruption offenses under Indonesian law. The legal framework in Indonesia recognizes corporations as subjects of criminal law, as outlined in Law No. 20 of 2001 concerning the Eradication of Corruption Crimes (UU Tipikor). However, there are still gaps in the law, particularly regarding main and additional penalties for corporate entities. The introduction of Law No. 1 of 2023 concerning the Criminal Code (KUHP Nusantara) addresses these shortcomings by providing more comprehensive regulations on corporate criminal liability, particularly for corruption-related offenses. This study employs a qualitative research approach, using legislative analysis, case law examination, and conceptual analysis. The research is doctrinal and juridical-normative, relying on literature studies and document analysis of statutory regulations and court decisions regarding corporate corruption. The study focuses on the corruption case involving PT. Sinarmas Asset Management (PT. SAM), where the corporation was held criminally liable under both the Anti-Corruption Law and the Indonesian Criminal Code. The research reveals that the Indonesian Criminal Code offers more detailed provisions, including additional penalties for corporations convicted of corruption. The case study also highlights significant legal developments in the trial process. Initially, the District Court convicted PT. SAM of corruption, but this verdict was overturned by the Jakarta High Court, which acquitted the company. However, the Supreme Court disagreed with the lower courts and upheld the conviction, continuing to impose penalties on PT. SAM for the mismanagement of unauthorized funds. This case underscores the complexities of corporate criminal liability in corruption cases and the evolving nature of judicial interpretations of corporate accountability in Indonesia.

Minerals are solid objects that can be found in nature, formed inorganically, with chemical composition at certain limits and have atoms arranged regularly. Rocks can be distinguished based on the formation process and mineral content. The purpose of this study is to identify minerals in sedimentary rocks and laterite deposits in this study used analytical methods, namely Binocular Microscope and XRD (X-Ray Diffraction) laboratory tests. XRD analysis is used to determine the type of mineral in the sample. Based on the results of the XRD X-Ray Diffraction lab test, each sample has a different mineral content.

People's mining activities in Gamey Village, Uwapa District, Nabire Regency, Central Papua Province are carried out to meet daily needs and improve the welfare of the local community. This mining activity is based on alluvial deposit conditions and is applied for mining sediments on the surface and using alcon machines. for high pressure water spray. This community mining activity is divided into several stages starting from preparation of mining land, processing and production processes as well as selling gold products for sale. This research aims to examine the gold processing used by small-scale miners in Uwapa District, Gamey Village, and its impact on the environment and public health. The main focus of this research is on the use of the sluice box method, which is the gold processing technique most commonly used by local communities. This method was chosen for its simplicity and low cost, although the gold recovery efficiency varies between 50-70%. Additionally, this research evaluates alternative technologies such as shake tables and centrifuges that can increase gold recovery efficiency and be more environmentally friendly. The research results show that the implementation of alternative technology requires training, procurement of adequate equipment and infrastructure as well as ongoing monitoring. By adopting better technology, it is hoped that gold mining activities in Gamey Village can run more productively and sustainably, improving community welfare without damaging the environment.

The prevalence of Ear, Nose, and Throat (ENT) diseases presents diagnostic challenges, especially in resource-limited settings. At THB Bekasi Hospital, constrained specialist availability and long consultation queues highlight the need for an accessible diagnostic solution. This study aims to develop an expert system for diagnosing ENT diseases using the Extreme Programming (XP) methodology, incorporating the forward chaining technique for inference. The research includes assessment, knowledge acquisition through expert consultations, system design, and rigorous testing. The system was developed as a mobile application using Android Studio, enabling users to input symptoms and receive real-time diagnostic insights. The knowledge base integrates data from medical experts, synthesizing 11 diseases and 35 symptoms into a robust decision-making framework. The diagnostic process applies predefined rules to ensure accuracy in identifying conditions such as sinusitis, laryngitis, and otitis. Evaluation results demonstrate a 100% match accuracy during testing with 15 test cases, confirming the system’s reliability. The application offers users rapid diagnostic assistance, promoting timely treatment for ENT issues, although it does not substitute medical professionals. By leveraging ubiquitous smartphone access, this system addresses gaps in healthcare accessibility and enhances patient autonomy. This research contributes a scalable framework for deploying expert systems in other medical domains. Future improvements include integrating geolocation services for nearby specialist referrals and adopting backward chaining for more complex diagnoses, thereby broadening its applicability and utility

Tobacco is one of the leading commodities in the agricultural sector. In the Indonesian agricultural sector, tobacco has been widely exported to various countries. Of the several tobacco export destination countries, Cambodia dominates the Indonesian tobacco export market. Problems related to fluctuations in Indonesia's export volume need serious attention, because this is important to understand the factors that influence the increase and decrease in the volume of Indonesian tobacco exports to Cambodia. Based on the description, the objectives of this study are (1) To analyze the influence of production volume, inflation, and the dollar exchange rate simultaneously on the volume of Indonesian tobacco exports to Cambodia, (2) To analyze the partial influence of production volume, inflation, and the dollar exchange rate on the volume of Indonesian tobacco exports to Cambodia. The data used in this study are secondary data with a total of 32 observations (years), using the multiple linear regression method. This study found that (1) Simultaneously, production volume, inflation, and the dollar exchange rate significantly affect the volume of Indonesian tobacco exports to Cambodia, and (2) Partially, production volume, inflation, and the dollar exchange rate have a positive and significant effect on the volume of Indonesian tobacco exports to Cambodia. Based on the results of the study, it is hoped that the government can pay attention to the causes of fluctuations in the volume of Indonesian tobacco exports.
