The objective this study is to analyze the implementation of Bandung Barat Regency Regional Regulation No. 5 of 2018 about the Placement and Protection of Indonesian Migrant Workers (PMI) originating from Bandung Barat Regency referring to the Hill and Hupe's theory of Policy Implementation. This matters all the more since the migrant worker-related cases that garner the highest volume if not interest–like illegal, clandestine worker departures, back wages, and exploitation–reflect the lack of protection systems, the unmet obligation towards the respect of individual rights and human dignity. This qualitative case study reveals key factors influencing policy implementation — low levels of socialization and knowledge about the regulation among migrant workers, absence of inter-agency coordination and poor resources for monitoring and enforcement In addition, it builds upon the variables presented by Hill and Hupe in order to present a more integrated analysis of the implementation process of the policy. These results highlight failures in the system, including the lack of inter- agency cross country collaboration and low resource allocation toward the functions that protect PMI. In light of this, the study makes a range of recommendations including for better policy socialization, improved inter-agency coordination and enforcement, and strengthening resourcing and legal compliance capabilities. Practical implications This study advances the theory of public administration and provides practical insights for policymakers, particularly for strengthening the protection of Indonesian migrant workers in an effective manner.

Organic waste management has become an urgent global issue, as the increasing volume of waste poses serious challenges to the environment. One innovative solution that is gaining increasing attention is Maggot cultivation, through a bioconversion process. Maggot bioconversion not only addresses the problem of organic waste but also offers new economic opportunities through the production of high-value resources. In addition, maggot cultivation can also contribute to addressing the high price of protein sources and the increasing demand for animal feed. As highlighted by a study, maggot bioconversion technology can address three main problems: the generation of organic waste, the high price of protein sources, and the increasing demand for animal feed. (Handayani et al., 2021). Maggot (Hermetia Illucens) is a black soldier fly larva that has a chewy texture, high protein and has the ability to secrete natural enzymes that help improve the digestive system of livestock.

This study evaluates the effectiveness of a hybrid citizen–AI legal monitoring system in enhancing urban environmental governance. The hybrid system integrates citizen-driven reporting platforms with AI-powered legal monitoring tools to address the challenges of weak public oversight in urban environmental management. By implementing the system in three metropolitan areas, the study explores how real-time data collection through citizen reports, combined with AI-driven analysis, can improve the accuracy, speed, and responsiveness of identifying environmental violations. The results showed a 45% improvement in oversight effectiveness, demonstrating the potential of hybrid systems to enhance monitoring capabilities beyond traditional methods. The AI system, capable of analyzing large datasets and providing timely insights, enabled quicker identification and categorization of violations such as pollution and waste management issues. The integration of citizen involvement through digital platforms allowed for more inclusive data collection, enhancing the quality and volume of information available for decision-making. This synergy between human participation and AI-driven analysis improved the speed of response to urban environmental challenges, making the system more adaptive and efficient. However, challenges such as data reliability and variable citizen participation rates were identified, suggesting the need for strategies to encourage consistent engagement and ensure the accuracy of reported data. The study concludes that hybrid citizen–AI systems can significantly improve urban governance by enhancing transparency, accountability, and responsiveness, offering a promising solution for cities seeking to address environmental issues more effectively.

This study analyzes noise levels caused by traffic activities and generator sets (genset) in the Semarang University environment. Measurements were conducted using descriptive analytical methods by comparing measurement results against noise quality standards according to KepmenLH No.48 of 1996.

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.  

This research aims to design and test a genset fuel conversion system from gasoline to HHO gas (brown gas) as a more environmentally friendly alternative. Conventional fossil-fueled generators face challenges in theform of limited resources and the impact of environmental pollution. In this study, HHO gas is produced through a water electrolysis process using an HHO generator that separates water molecules into hydrogen and oxygen using electric current. The test results show that increasing the voltage from 2.58 V to 5.12 V significantly increases the volume of gas produced. At a voltage of 2.58 V, the gas volume reached 110 ml, and increased to 750 ml at a voltage of 4.72 V. The generator set was successfully operated for 1 minute 15 seconds with HHO gas using a separate battery power source. These results demonstrate the potential of HHO gas as an efficient alternative fuel for generator sets. This study recommends further testing with voltage and current variations to find the optimal configuration, as well as the use of a larger power source to increase the efficiency of HHO gas electrolysis.

Plastic waste is one of the sources of problems for all living things, especially humans and their environment. So there is a need for awareness of this adverse impact. Measures such as the use of environmentally friendly alternatives, plastic reduction education, and government policies to limit the production and distribution of single-use plastics are increasingly being promoted. By implementing these alternative measures, it can have an impact on keeping our earth clean. The method used in this research is normative juridical, this research leads to the scientific field of law, regulations, and provisions that apply to a problem. In this case, a review of laws and regulations relating to plastic waste reduction policies is carried out. Meanwhile, the meaning of normative legal research is research conducted by looking at any library material as secondary data and is also considered as library legal research. According to the Jambeck Research Group report in 2015, Indonesia ranks second after China in the contribution of plastic waste to the ocean, with an estimated 3.2 million tons of plastic waste per year, and around 640,000-1.29 million tons end up at sea. By 2024, plastic waste in Indonesia is projected to reach around 13.98% of the total national waste generation, with an estimated volume of around 9.9 million tons. As a wise individual, we should not only rely on government policies in dealing with plastic waste, but each individual must be educated in order to create awareness of the dangers of the impact caused by the waste of plastic use.

In conclusion, the Suroboyo Bus policy has great potential to reduce congestion if supported by infrastructure development and increasing public awareness of the use of public transportation.

The dance work entitled Malungunjei’s is a new work that develops the mangunjei movement motif in one of the Manduda dance motif movements. Malungunje’si comes from one of the names of the Batak Simalungun dance motifs, namely mangunjei. Mangunjei is a movement of both hands crossed in front of the chest and both hands on the left and right sides by turning the palms of the hands. The theme of this dance work is non-literal, because the presentation of this dance work is a development or exploration of the essence of the Mangunjei motif by utilizing intensity, large volume, and wide space for movement. Malungunjei's work is a group choreography consisting of three female dancers and two male dancers, a total of five dancers who will be composed in a large group composition and a small group by paying attention to the arrangement of parts. The costumes in this choreography use hiou material and the choice of colors is more on red, black and white, all three are colors used in every Batak Simalungun traditional activity. The dance music is formatted in MIDI with patterns resulting from the development of the Batak Simalungun gonrang. This work uses the exploration method as an initial part in developing the creativity of the creation process, improvisation to find movements by chance or spontaneously, composition to arrange the movements that have been obtained, and periodic evaluation and correction of the process.

How Cola nitida could affect the urine calcium and magnesium concentrations of the male human subjects in comparison to the female counterpart were focused on. Sixty subjects (males=30 and females=30) and unaccustomed to Cola nut eating were involved. Their age range was between 18 and 28years. Three (3) sub-categories were involved: underweight=10, normal weight=10 and overweight=10. Hypertensive, renal and any subject with cardio-pulmonary-related conditions were exempted from the study. The normal chamber temperature, (RT=270C and RH=70%), the raised chamber temperature (RT =370C and RH=90%) were studied. Sequel to the foregoing, the subjects sat quietly in the sweat chamber for 20 minutes. The third experimental condition was the normal chamber temperature with exercise (RT=270C and RH=70%) and the subjects rode a bicycle ergometer at 750J/minute for 20 minutes. All of these happened prior to the consumption Cola nitida. Ahead of the experimentation in the sweat chamber, the subject urinated in a container in order for the timed urine volume to be measured and urine was again taken at the end of the experimentation that was also measured in order to obtain the actual urine volume within the given period. Thereafter, the urinary flow rate was calculated. The urine calcium and magnesium concentrations were likewise estimated. 0.5g/kg body weight of Cola nitida was given to each subject and chewed as a bolus. After swallowing, 50ml of deionized water was given to each subject to drink and the subject was allowed to rest for 90 minutes before being brought into the sweat chamber. The results showed that in respect to urine Ca ions concentration, no significant change was observed in a comparison between the males and females after the ingestion of Cola nitida under normal, raised temperature and exercise experimental conditions. As regards urine Mg ions concentration, no significant change was observed in a comparison between the males and females after the ingestion of Cola nitida under normal and exercise experimental conditions. However, there was a significant increase in Mg ions concentration in the female UW and NW subjects compared to the males after the consumption of Cola nitida under raised temperature condition.

Indonesia has significant fisheries potential due to its vast waters. Its abundant fishery resources have strong export potential. However, export activities often face challenges that cause export volumes to fluctuate. This fluctuation is influenced by various factors. These factors can be minimized using statistical methods such as Principal Component Analysis (PCA) and Factor Analysis. This study includes data characterization for each variable and testing PCA and factor analysis assumptions, including multivariate normality testing, independence testing (Bartlett's test), sampling adequacy (KMO test), anti-image correlation testing, PCA testing, and factor analysis. The results indicate that the percentage contribution of fisheries to GDP, the number of coastal villages with disaster mitigation facilities, and the average daily per capita calorie consumption from fish are relatively less dispersed and not highly variable around the mean. Additionally, all data meet the assumptions, and the sample size is adequate. Factors such as aquaculture pond production and the percentage contribution of fisheries to GDP sufficiently explain the data variations.

Waste is leftover material that is considered to have no economic value, but its existence cannot be avoided in people's social life. In Karanglangon Hamlet, the increase in population that occurs every year increases the volume of waste produced. As the population increases, household waste production and other activities also increase, thereby exacerbating waste management problems in the region. If not managed properly, the increasing amount of waste can have various negative impacts, both on public health and the surrounding environment, such as air, land and water pollution. This problem demands more attention from various parties to find appropriate and sustainable solutions. This research aims to identify in more depth the problems related to waste management at the Dusun Karanglangon TPS using the PAR (Participatory Action Research) approach method. The research results revealed that the condition of the waste at the TPS had a significant negative impact on the surrounding environment. The main causes are limited facilities, minimal budgets, and inadequate waste management standards, resulting in the accumulation of waste and increasingly severe environmental pollution.
