Aquaculture is a significant industry in Indonesia, but water quality management remains a challenge, impacting fish health and productivity. This paper presents a low-cost, IoT-based water quality monitoring system designed for small-scale aquaculture operations. The system continuously measures pH, temperature, dissolved oxygen, and turbidity, providing farmers with real-time data via a mobile application. Field trials in Java demonstrate the system's effectiveness in maintaining optimal water conditions, reducing fish mortality, and increasing yield. The study suggests that affordable, technology-driven solutions can substantially benefit the aquaculture sector in Indonesia.

Urban traffic congestion is a growing problem in Indonesian cities, affecting economic productivity and quality of life. This research explores the development of a smart traffic management system utilizing Internet of Things (IoT) sensors and artificial intelligence (AI) algorithms to analyze traffic patterns and optimize flow. The proposed system collects real-time data and uses predictive analytics to adjust traffic signals dynamically. Field tests in Jakarta demonstrate a 15% improvement in traffic flow and reduced travel times during peak hours. The findings suggest significant potential for scalable smart city solutions in urban traffic management across Indonesia.

This paper presents an optimization approach for a hybrid photovoltaic (PV)-wind-battery energy system tailored for remote areas in Indonesia. Due to the archipelagic nature of the country, many remote areas lack access to the national power grid, making renewable energy solutions crucial. This study utilizes a genetic algorithm to optimize system configurations, balancing energy production, storage requirements, and cost efficiency. Results indicate that the proposed hybrid system can meet local demand with high reliability and at lower costs compared to diesel generators. The study also addresses environmental and social impacts, proposing sustainable energy strategies for Indonesia's underserved regions.

The construction industry in Indonesia faces challenges in finding sustainable materials for concrete production. This paper investigates the potential of rice husk ash (RHA) and palm oil fuel ash (POFA) as alternative supplementary cementitious materials (SCMs) in concrete. Both RHA and POFA are abundant agricultural by-products in Indonesia. Laboratory tests indicate that their incorporation enhances the compressive strength, durability, and sustainability of concrete. The findings highlight the dual benefit of reducing industrial waste and creating eco-friendly construction materials, thus contributing to the development of green infrastructure in Indonesia.

Adolescent girls with good nutritional status are one of the efforts to prevent stunting. Indonesia is faced with three burdens of nutritional problems, namely the high prevalence of stunting, wasting, obesity and anemia.  Good nutritional status can be realized if balanced nutrition practices are carried out properly.

Cosmetics have varied purposes, including cleansing, increasing brightness, changing appearance, and protecting or maintaining certain conditions. The applicable cosmetics regulations are explained in the BPOM provisions, which mandate registration before cosmetics can be used by consumers. In this research, the results of two literature reviews are presented that support this statement. The first study by (Chandra Adi Gunawan Putra, 2023) shows that the need for state involvement in protecting consumers arises because of the power imbalance between business actors and consumers. The second study by (Ribka Amanda Dera, 2019) the regulation of cosmetic products has been regulated by BPOM number 12 of 2020 article 2 paragraph 1 which emphasizes that cosmetics producers must ensure that their products which will be distributed both domestically and abroad meet the criteria, safety and security standards. benefits, quality marking, and claims. The results of both studies show that the importance of terms and conditions related to cosmetics are under law and regulated in the Republic of Indonesia Constitution, the Health Law, provisions issued by the Minister of Health and decisions taken by the Head of the Republic of Indonesia Food and Drug Supervisory Agency and in BPOM regulations starting from formulation to product withdrawal. So that any party who commits an illegal act by producing or distributing pharmaceutical or cosmetic products without a permit will receive applicable sanctions in accordance with legal provisions.

Retirement is a phase which has to be faced by a worker in the completion of his work duties. The preparation of the process draws attention to the people who experience it or the stakeholders to provide policies on the retirement matters. This research aims to provide information about the factors which influence the welfare of life (wellbeing) in retirement. The current study used a literature review that involved nine journals that studied retirement. This research was conducted by searching for articles using an application called Publish Perish by using two keywords “Retreatment” and “Pension”. The crossref (cross   reference) search found that there are 5 journals from the keyword “Pension” and 10 journals from the keyword “retreatment”.  After the exclusion, nine journals were obtained according to the researcher’s desire.

Yuliddin Away Tapaktuan General Hospital and become a guideline for improving health services for toddlers with bronchopneumonia.  

Hypertension, often called the "silent killer," is a leading non-communicable disease contributing to high mortality and morbidity, particularly in the elderly. As individuals age, peripheral blood vessel elasticity decreases, increasing vascular resistance and leading to systolic hypertension, commonly seen in older adults. Hypertension requires long-term treatment, which can result in non-compliance among elderly patients. Family support plays a crucial role in assisting and encouraging adherence to treatment regimens. This quantitative correlation study, with a cross-sectional approach, aimed to examine the relationship between emotional family support and treatment compliance in elderly hypertensive patients. The study was conducted at the Sei Agul Health Center, with a sample size of 65 elderly individuals selected using the Slovin formula and purposive sampling technique in October 2023. The Morisky Medication Adherence Scale (MMAS-8) was used to measure treatment compliance, while the emotional support instrument was developed by the researcher. Data were analyzed using the chi-square test, showing a significant relationship between emotional family support and treatment compliance (p-value < 0.05). The findings conclude that emotional support from family positively influences the compliance of elderly patients undergoing hypertension treatment at the Sei Agul Health Center. Health workers are encouraged to involve families in supporting hypertensive patients to enhance treatment outcomes.

This research aims to formulate a transformation model for stunting assistance by the Kunduran District Stunting Team, Blora Regency. The study uses qualitative methods with a phenomenological approach through in-depth interviews. The results of the research show that the implementation of the role of companion for stunting families in Kunduran District still faces several obstacles, such as limited competence of companions, less effective counselling methods, barriers to access to health services for stunting families, and early detection and supplementation of at-risk pregnant women. A transformation of the stunting assistance paradigm is needed from the old top-down approach to a dialogical and collaborative model between the assistant and the family. Transformation is required by increasing companions' competence, interactive counselling, an organized referral system, early detection of at-risk pregnant women, and increasing access to nutritional supplementation. With comprehensive transformation, it is hoped that supporting stunted families will be more effective in accelerating the reduction of stunting in Kunduran District and Blora Regency. Regional government support through policies and funding is urgently needed to optimize the transformation of the role of family companions.
