Investment is an essential instrument for capitalist countries to boost the national economy and create job opportunities for the community. Investment in Indonesia began with Foreign Investment Law No. 56 of 1964, which was later updated with Foreign Investment Law No. 25 of 2007 in line with the times. To increase investor interest in entering Indonesia, the government enacted Job Creation Law No. 11 of 2020, which was further updated through the Job Creation Law up to 2023. Due to the complexity and increasing number of investors facing obstacles such as land acquisition and regional policies, a Presidential Regulation on National Strategic Projects (PSN) was issued. The government's hopes and expectations for smooth investor operations do not always align with implementation. Specifically, PSNs often result in agrarian conflicts for local residents whose land is taken over for PSN purposes. In the context of investment in Batam, particularly the Rempang Eco-City Development Plan in the Rempang-Galang area, clashes occurred and drew national attention and concern from various experts when land measurements began by PT MEG, escorted by the Joint Team comprising police, TNI, and the Ditpam Batam Management Agency (BP Batam). They have not reached an agreement but are already being pushed for swift execution. The obstacles to investment in the PSN Rempang Eco-City include conflicts arising from legal uncertainties over land ownership since the administrative change from Bintan Selatan District to Batam City, becoming Galang District since 1980. Represented by their legal counsel LBH GP Asnhor, they demand legal certainty over their ancestral land to be issued certificates, enabling fair and humane compensation. This demand has been submitted to President Joko Widodo regarding the request for land legality for the villages on Rempang Island, Galang Island, and New Galang Island on behalf of the chairman of the Local Indigenous People's Relatives (KERAMAT) Gerisman Ahmad. Due to these obstacles and conflicts, the central government, through President Joko Widodo, issued Presidential Regulation No. 78 of 2023 on Handling Social Community Impacts in the Context of Land Provision for National Development. However, as of July 2024, there has not been a comprehensive agreement between the community, the Batam City government, and the head of BP Batam. The government is taking a softer approach by personally approaching residents to relocate to Tanjung Banon, where four model houses have been provided as promised incentives for those willing to move.

Batam as an industrial area which development is carried out by the Batam Island Industrial Area Development Authority agency, has also been expanded into an autonomous region which later give birth to the Batam City Government. The existence of these two government agencies then creates problems in the management of Batam City in the form of overlapping / dualism of authority. To overcome this problem, the government then issued a new breakthrough by setting the Head of the Batam Concession Agency to be held ex-officio by the Mayor of Batam in the hope that the implementation of his duties and authority would be more effective. Therefore, the purpose of this thesis research is first, the implementation of the Mayor of Batam ex Officio Head of Business Agency. Second, the ideal arrangement for the relationship between the Batam City Government and the Business Agency and third, obstacles in the implementation of ex officio. This type of research can be classified into the juridical sociological research type, because it wants to see the correlation between the law and what happens in the field so as to reveal the effectiveness of the law's application. With the research location located at the Batam Concession Agency and the Batam City Government. This research uses data sources in the form of primary data and secondary data, and data collection techniques are carried out by means of interviews, questionnaires and literature review. From the study, there are three main points that can be concluded. First, the Mayor of Batam, Muhammad Rudi, succeeded in implementing the central government's decision regarding the position of Head of the Batam Business Agency, concurrently ex-officio by the Mayor of Batam. Second, it is necessary to study Government Regulation Number 41 of 2021. and third, social problems, such as illegal houses, unemployment, crime, and others, arise as a result of inequality, public policy, inability to compete and others. As for the advice from the author; First, the need for Human Resource governance to support the duties and functions of each work unit Second, the need to re-assess/test the material of government regulation number 41 of 2021 and third, the need to develop IT innovation in the context of improving services and reporting.

Indonesia is rich in diverse natural resources, namely animal natural resources and vegetable natural resources. One of the gifts of Almighty God which can be used as a source of the country's economy for national development. However, as time goes by, the species that breed in the forest are starting to become endangered. This is caused by the behavior of people or business entities who only think about personal interests without thinking about the impact of what they have done. A corporation involved in crimes involving protected wild animals will be charged in accordance with the applicable articles to provide a deterrent effect against the perpetrators. This research aims to find out the types of crimes against protected wild animals and to find out how law enforcement is carried out against corporations that commit crimes against protected wild animals based on Law of the Republic of Indonesia Number 5 of 1990 concerning Conservation of Living Natural Resources and Their Ecosystems. This research is normative legal research. The data collection method is by conducting a literature review of legal materials whose data sources come from secondary legal materials, namely primary legal materials, secondary legal materials and tertiary legal materials. The data is described qualitatively descriptively and then analyzed to obtain conclusions from the problem formulations.

Purpose: Investment is the allocation of funds with the aim of obtaining profits in the future. An example of the investment instruments with high returns and high risks are stocks. The risks associated with the investment can be reduced by forming a portfolio of quality stocks optimized through mean-variance (MV). This is necessary because successful selection of high-quality stocks depends on the future performance which can be determined through accurate price prediction.
Methods: Stock price can be predicted through the adoption of different forms of deep learning methods. Therefore, BiLSTM and LSTM models were applied in this research using the stocks listed on the LQ45 index as case study.
Result: The utilization of LSTM and BiLSTM models for stock price prediction produced favorable outcomes. It was observed that BiLSTM outperformed LSTM by achieving an average MAPE value of 2.1765, MAE of 104.05, and RMSE of 139.04. The model was subsequently applied to predict a set of stocks with the most promising returns which were later incorporated into the portfolio and further optimized using the Mean-Variance (MV). The results from the optimization and evaluation of the portfolio showed that the BiLSTM+MV strategy proposed had the highest Sharpe Ratio value at k=4 compared to the other models. The stocks found in the optimal portfolio were BRPT with a weight of 19.7%, ACES had 16.9%, MAPI 11.8%, and BMRI at 51.6%.
Novelty: This research conducted a novel comparison of LSTM and BiLSTM models for the prediction of stock prices of companies listed in the LQ45 index which were further used to construct a portfolio. Past research showed that the development of portfolios based on predictions was not popular.

Purpose: This research aims to develop a system for detecting the credibility of information on social media X by classifying tweets as credible or non-credible. Additionally, it seeks to improve the accuracy of classification and prediction of information credibility using feature extraction methods, semantic features, feature expansion, and optimization.
Methods: The system is built using a deep learning approach with Long Short-Term Memory (LSTM), Term Frequency-Inverse Document Frequency (TF-IDF), Robustly optimized BERT Approach (RoBERTa), Global Vector (GloVe), and Particle Swarm Optimization (PSO). The dataset consists of 54,766 Indonesian tweets from social media X, focusing on the 2024 General Election and using several keywords such as ‘Pemilu 2024’, ‘Pilpres 2024’, ‘anies baswedan’, ‘Prabowo’, ‘#GanjarPranowo’, and ‘#debatCapres’.
Result: The results of this study show that the highest accuracy achieved is 89.09% using LSTM with an 80:20 data split, baseline unigram, RoBERTa, Top1 corpus IndoNews, and PSO of the LSTM model’s hyperparameters, resulting in a highly significant statistical improvement of 0.96% over the baseline model.
Novelty: This research contributes to information credibility classification research using RoBERTa to add semantic features and GloVe to expand features by utilizing a built corpus and finding similar words to connect with these expanded features. Additionally, PSO is applied to find the optimal hyperparameters, thereby improving the performance and accuracy of the LSTM classification model.

This study aims to determine the validity of the presumption of innocence principle against perpetrators or suspected perpetrators of criminal acts of terrorism committed by law enforcement officials, especially Densus 88. This paper uses a statute approach and a conceptual approach. The results showed that the principle of presumption of innocence in handling criminal acts of terrorism is, in fact, still often ignored by law enforcement officials. Even the data obtained shows that several suspects/perpetrators have died during the legal process they underwent, as well as the actions of law enforcement officials who often commit acts that exceed limits and violate human rights. This principle needs to be implemented and strictly regulated in the Criminal Procedure Code as the master procedural law as well as in the law on the eradication of criminal acts of terrorism so that the strength and application of this principle increasingly get a place and position that can protect perpetrators/suspected perpetrators of criminal acts of terrorism.
