The development of science and technology has caused the military forces of many countries to spend a lot of money and energy on research and development of automated, multi-faceted and effective (including lethal) technology. From a maritime perspective, this development has attracted widespread interest from many navies in underwater technology such as submarines and unmanned submarines. Modern submarines are now capable of moving at high speeds with very low noise levels, in addition to being able to carry weapons with very high destructive power and carry out diving operations for long periods of time. At the same time, modern unmanned underwater vehicles are now capable of carrying out various types of operations, including surveillance, minelaying, underwater surveys, and even the ability to carry long-range weapons up to thousands of kilometers away. It is undeniable that the development of other countries' navies is a real threat to Indonesia. To overcome this problem, an underwater surveillance system is needed in Indonesian waters, especially in deep waters which are likely to be used by other countries such as ALKI to carry out covert operations. This underwater surveillance system must utilize existing technological developments in order to carry out its functions effectively and sustainably, especially by using autonomous underwater vehicles (USVs). The use of USV in surveillance systems will save a lot of costs because it does not waste budget on expensive logistics, personnel, maintenance, and spare parts. This research is a research and development using mixed research methods (qualitative and quantitative) with research products in conceptual form. In this underwater surveillance system concept, USV will automatically conduct underwater contact surveillance along the ALKI II water body using sensors and software integrated into the USV.

Background: Stunting is a chronic nutritional disorderl in toddlers that is permanent and irreparable (irreversible) if it occurs during the First 1000 Days of Life (HPK). One significant risk factor is birth spacing that is too close, which affects the mother's nutritional status and the quality of fetal nutrient intake. Objective: This study aimed to analyze the relationship between birth spacing and the incidence of stunting among toddlers on Morotai Island. Methods: An analytical study with a cross-sectional design was conducted on 30 respondents selected through accidental sampling in the Community Health Center (Puskesmas) area of Morotai. Data were collected through questionnaires, MCH (Maternal and Child Health) books, and anthropometric measurements, then analyzed using Simple Logistic Regression test. Results: The majority of respondents had a birth spacing of 3-4 years (40%), but the prevalence of stunting remained quite high at 43.3%. The statistical test results showed a p-value = 0.005 (p < 0.05), proving a significant relationship between birth spacing and the incidence of stunting. Conclusion: There is a significant relationship between pregnancy/birth spacing and the incidence of stunting among toddlers on Morotai Island.

The rapid increase in Ro-Ro (Roll-On/Roll-Off) vessel and vehicle traffic at Tanjung Perak Port, Surabaya, has exposed critical inefficiencies in port operations, particularly at key berths such as Jamrud Utara and Jamrud Selatan. These inefficiencies manifest as prolonged queuing times for Ro-Ro vessels and land-based vehicle congestion, leading to delays in cargo handling and increased operational costs. This study aims to evaluate the operational performance of Ro-Ro terminals based on queue time indicators for both Ro-Ro vessels and vehicles. Employing a quantitative descriptive approach, the research integrates the M/M/c queuing model and Fishbone Diagram analysis to identify systemic causes of operational delays and overcapacity. The study reveals that berth utilization rates exceed 75%, indicating saturation, while limited buffer zones and disorganized traffic flow exacerbate vehicle queues. As a case study, the findings offer data-driven insights and practical recommendations, including schedule optimization, dedicated traffic lanes, and infrastructural upgrades to mitigate congestion. The proposed framework not only enhances service efficiency at the port but also contributes to broader logistics performance in Eastern Indonesia. By combining classical queuing theory with root cause analysis, this research introduces a methodological synergy that can be replicated across other Ro-Ro terminals facing similar challenges. The findings underscore the urgent need for integrated port traffic management and infrastructural adaptability in response to growing maritime logistics demands.

The objective of this research is to assess the use of discovery learning techniques in enhancing students' engagement and critical thinking abilities in Pancasila and Citizenship Education courses. Discovery learning is a teaching method that encourages students to learn on their own by observing, exploring, and verifying what they learn. The study's findings suggest that the implementation of discovery learning may enhance students' engagement in debates, facilitate inquiry, and encourage the expression of viewpoints. Also, students' critical thinking abilities became better because they could examine material, come to conclusions, and solve issues in a logical way. However, there were several problems with its use, such as not having enough time, students being at different levels of preparation, and problems with managing the classroom. With careful preparation, good time management, and a lot of help for students, these problems may be solved. The discovery learning technique has been shown to be beneficial in enhancing the quality of learning. It is also particularly useful for helping students become active, critical thinkers who can solve issues on their own.

This study examines the persuasive strategies used by Anies Baswedan in his TEDx speech titled “Governments, Make Public Transport Equitable.” As the Governor of Jakarta, Baswedan delivered the speech on a global platform to advocate for equitable, inclusive, and sustainable public transportation. The research focuses on how he employs Aristotle’s classical rhetorical appeals, namely ethos to establish credibility, pathos to create emotional connection, and logos to present logical reasoning, in order to engage and persuade his audience. Using qualitative rhetorical analysis, the study explores how these appeals are combined and positioned throughout the speech. The official transcript was carefully analyzed to identify statements that reflect each persuasive strategy. The findings show that logos is the most dominant appeal, as Baswedan presents data, measurable goals, and clear policy outcomes. Ethos is conveyed through his position, achievements, and inclusive vision, while pathos emerges in moments where he highlights social justice, the urgency of addressing climate change, and the unifying power of public transport. This research shows that rhetorical appeals in political speeches like Baswedan’s are not applied in a strict sequence but are interwoven to strengthen the overall persuasive impact. The study offers insight into how classical rhetorical strategies are applied in modern communication platforms such as TEDx.

This research aims to examine and describe the implementation of a digital-based Cost of Revenue recording system at PT Alam Mulya as a logistics service company.

This study employs a qualitative descriptive approach, utilizing data collection techniques through literature review, direct observation, and interviews with parties involved in the company's financial recording process. The research findings indicate that the use of the Shortcut-AM application can accelerate the real-time recording of direct costs, reduce the risk of recording errors, and facilitate internal monitoring and audits. However, the effectiveness of the system still faces several challenges, such as delays in collecting supporting documents, account classification errors, and discrepancies between account mutation data and internal records. These challenges highlight the importance of cross-divisional coordination, ongoing technical training, and strengthening internal controls to ensure the system operates optimally. Thus, the digital-based recording system not only enhances operational efficiency but also serves as an essential foundation for maintaining the integrity and accountability of the company's financial reports.

Efficient resource allocation is a major challenge in various sectors, especially when faced with limitations in quantity, time, and cost. This study aims to examine the application of linear programming as an optimization method in solving assignment problems, where a number of resources must be optimally allocated to a number of specific tasks. Through a literature study approach, this study examines various relevant previous study results, especially in the Indonesian context. The results of the study indicate that linear programming is able to improve operational efficiency, reduce costs, and produce a more balanced task distribution. However, this model has limitations in dealing with non-linear conditions and data uncertainty, so integration with other methods such as fuzzy logic or genetic algorithms is needed. This study is expected to broaden the understanding of the benefits of linear programming and encourage its wider application in quantitative-based decision making.

Late payment of accounts receivable is a serious challenge that can disrupt the stability of the company's cash flow and financial performance. This study aims to evaluate the role of risk management in minimizing late payment of accounts receivable at PT Alam Mulya, a logistics company in Surabaya. The research method used is descriptive qualitative with a case study approach, through direct observation, interviews, and documentation during the five-month internship period. The results showed that the company has implemented risk management principles, such as customer identification, setting credit limits, monitoring maturity, and implementing active collection. However, the implementation has not been thorough and consistent, especially in the aspects of using digital systems, documenting credit policies, and applying sanctions for late payments. It was also found that decision interventions based on personal relationships hindered the effectiveness of risk control. This study recommends the implementation of an integrated digital system, the establishment of a written credit policy, and staff training related to risk management and collection. By strengthening comprehensive risk management, the company is expected to improve the efficiency of receivables management and maintain optimal cash flow sustainability.

The distribution of sugarcane from farmers to sugar mills in Indonesia continues to face various challenges, particularly in terms of logistical efficiency and farmers’ dependency on intermediaries. This study aims to analyze the role of intermediaries in determining the efficiency of sugarcane distribution, using a case study in Kedungmakam Village, Tuban Regency. A qualitative approach with a case study design was employed, enabling an in-depth understanding of distribution practices directly in the field. Data were collected through field observations, in-depth interviews with farmers, intermediaries, and retail traders, as well as supporting documentation. The results indicate that intermediaries play a crucial role in providing production capital, scheduling harvests, and managing transportation of sugarcane to the mills. However, their dominance, in the absence of formal contracts, creates relationship imbalances and weakens the bargaining position of farmers. Furthermore, geographical barriers, limited access to market information, and the lack of independent distribution infrastructure exacerbate inefficiencies and reduce fairness in the existing distribution system. Therefore, strengthening farmer institutions, improving contract transparency, and enhancing access to logistics and information are recommended as long-term solutions.

This study aims to examine public preferences for online shopping platforms and the relationship between these preferences and patriotism. This is based on the fact that online shopping activities, particularly in Indonesia, are predominantly carried out by young people. Preferences for online shopping platforms are often influenced by factors such as price, shipping speed, and discounts. However, non-economic factors, such as patriotism or love for the country, also play an important role in choosing an online shopping platform. This research uses a descriptive quantitative approach with a Likert scale-based questionnaire instrument to measure two main variables: consumer patriotism and preference for online shopping platforms. The results of data analysis using binary logistic regression show that patriotism has a significant influence on the selection of online shopping platforms. Although more people prefer Shopee, the presence of Tokopedia, as a symbolic representation of economic nationalism, remains prominent. This suggests that patriotism can influence consumer behavior, even in a digital context that is often assumed to be neutral to national values.

This study aims to analyze the effect of maqashid sharia on Muslim women's happiness in Indonesia, using data from the Indonesian Family Life Survey (IFLS) 5th wave 2014. Maqashid sharia, as a core concept in Islamic law, focuses on the maintenance of five main aspects, namely religion (ad-din), soul (an-nafs), intellect (al-aql), offspring (an-nasl), and property (al-mal). This study examines whether the implementation of maqashid sharia principles coupled with region of residence as a control variable has a significant impact on the subjective happiness of Muslim women in Indonesia. Using logit regression method and STATA software, this study found that the maintenance of health (soul), education (mind), and income (wealth) has a significant positive effect on Muslimah's happiness, heredity (lineage) shows an insignificant negative effect, religiosity (religion) shows a positive and significant relationship, while the region of residence has an insignificant negative relationship with the level of happiness of Muslimah in Indonesia. These results indicate that the subjective happiness of Indonesian Muslim women is more influenced by material dimensions than philosophical or spiritual matters. This research is expected to contribute to the formulation of public policies that support the social welfare of Muslimahs based on maqashid sharia.
