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.

<p><em>After graduating, many vocational school students take part directly in the work. One of them is vocational school students majoring in construction who can immediately work in the world of construction or projects. In the implementation of construction, many work accidents occur which are caused by human factors, because of understanding of the dangers in construction projects. It was recorded by the Social Security Administering Agency (BPJS) for Employment that from January to November 2022 there have been 265,334 work accidents in Indonesia. Therefore, students need to be given education about Occupational Health and Safety (K3). The aim is for the graduate to always apply K3 during construction so that graduates do not experience work accidents. Education was carried out through the presentation of material about K3 by the USM PKM team and continued with a question and answer session. Participants were very enthusiastic about participating in educational activities. It was shown from a lack of participants who asked questions to the PKM team. Apart from that, the results showed that 81% of the students thought that the PKM material was in line with community needs and that the overall PKM activities provided benefits.</em></p>

This research is motivated by the importance of the role of KSOP in ensuring that ship guidance at the port is carried out in accordance with the set safety standards, as well as various obstacles that hinder the optimization of the implementation of these responsibilities. These obstacles include limited human resources, budgets, infrastructure, and ineffective coordination and communication. Research Objectives The purpose of this study is to analyze and evaluate the accountability of KSOP in the implementation of guidance at Batam City Port, identify the obstacles faced, and formulate efforts that can be made to overcome these obstacles. Research Methods This research uses normative juridical and empirical sociological methods. The normative juridical method is carried out through a literature study of the laws and regulations that regulate ship guidance and the responsibilities of KSOP. Meanwhile, empirical sociological methods are carried out through observation, interviews, and direct data collection from the Batam Special KSOP and other related parties. Research Results The results of the study show that the implementation of KSOP accountability in the implementation of guidance at the Port of Batam City has not run optimally. Obstacles faced include limited human resources, inadequate budgets, outdated infrastructure and technology, and lack of coordination and communication. In addition, awareness and compliance with safety procedures still need to be increased. Suggestions This study suggests increasing the recruitment and training of ship guides, optimizing budgets, modernizing navigation equipment and communication technology, simplifying regulations, and improving coordination and communication between related parties. With these steps, KSOP is expected to be more effective in supervising and ensuring the implementation of safe and efficient guidance at the Port of Batam City.

Batam Port is one of the strategic ports in Indonesia that plays an important role in the flow of goods and passengers and supports regional and international connectivity. As a port with mandatory pilotage waters, pilotage and towing services are vital components in ensuring the safety and efficiency of port operations. The imposition of Non-Tax State Revenue (PNBP) of 5% from these services aims to increase state revenue and the quality of port services. However, the implementation of this policy raises various challenges, such as overlapping levies that increase ship operational costs and low levels of user compliance.This study aims to analyze the legal regulations, implementation, and impact of the imposition and management of PNBP contributions of 5% from pilotage and towing services in Class II Pilotage Waters of Batam Port. The research method used is qualitative with data collection techniques through in-depth interviews, observations, and documentation studies. Research respondents included officials of the Batam Special Harbormaster and Port Authority Office (KSOP), Port Business Entities holding pilotage delegations, shipping companies, and port service user.The results of the study show that the imposition of 5% PNBP is supported by a strong legal basis, but its implementation still faces obstacles such as high operational costs due to overlapping levies and low understanding and compliance of service users. The management of PNBP funds that is not transparent is also an obstacle in achieving the goal of improving port services and infrastructure. To overcome this problem, efforts are needed to harmonize levy policies, increase transparency and accountability in fund management, and provide more effective education and socialization to the maritime community. Suggestions submitted include harmonization of policies between KSOP Batam and the Port Business Entity BP Batam, increasing socialization and education to service users, and reviewing regulations by the government to ensure port efficiency and competitiveness. With these steps, it is hoped that the implementation and management of 5% PNBP can be more efficient, fair, and provide optimal benefits for all stakeholders in Batam Port.
