The implementation of blue economy policies in Tanjungpinang City, the capital of Riau Islands Province, aims to foster sustainable urban development by leveraging marine and coastal resources. This study explores the potential and opportunities of blue economy principles to enhance economic growth, social welfare, and environmental sustainability. Utilizing a qualitative approach, the research evaluates local government policy documents and collaborates with industry stakeholders to assess the impact of these policies. Findings reveal that Tanjungpinang’s strategic maritime location supports significant fishery production (118,661 tons in 2023) and tourism growth, creating jobs and reducing coastal poverty. Key programs include sustainable marine resource management, fishery processing industry development, human resource capacity building, market access optimization, eco-friendly infrastructure, and environmental policy enforcement. These initiatives promote ecological sustainability, economic value, and social inclusivity. However, challenges such as limited processing scales, resource continuity, and environmental pollution persist. The study underscores the need for coordinated governance, technological investment, and community participation to ensure long-term benefits. Tanjungpinang’s blue economy model offers a replicable framework for sustainable urban development in coastal regions.

The ratification of the new Criminal Code (KUHP) through Law Number 1 of 2023 marks an important milestone in the history of Indonesian criminal law. The new Criminal Code replaces the colonial product that has been in place for more than a century and brings significant updates, especially in the regulation of gender-based crimes such as sexual and psychological violence. The recognition of these forms of violence is a response to the demands of civil society and is part of Indonesia's commitment to international human rights instruments. However, the effectiveness of such arrangements still faces serious challenges, such as the narrowness of the criminal formulation, the high burden of proof, and the potential for gender bias in the criminal justice system. In this context, criminal law should not only be a means of repression, but also carry out preventive and protective functions through holistic criminal policies. An integrative approach that combines penal and non-penal strategies is important to address the complexity of gender-based violence that is structural and multidimensional. This article aims to critically evaluate the provisions of the new Criminal Code related to sexual and psychological violence in the perspective of gender-responsive criminal policy. The evaluation was carried out taking into account the principles of restorative justice, the protection of victims' rights, and the need for social transformation that supports equality and non-discrimination. The results of this study are expected to be an input for the improvement of a criminal law system that is fairer and on the side of victims, especially women and other vulnerable groups.

The enactment of Law No. 1 of 2023 concerning the Criminal Code (KUHP) has brought a number of controversies, one of which is related to the revival of provisions regarding the criminal act of insulting the President and Vice President. This article aims to critically examine these provisions in the perspective of the freedom of expression guaranteed by the Indonesian constitution and international human rights instruments. This research uses a normative juridical approach with an analysis of the norms in the new Criminal Code, the 1945 Constitution, as well as international treaties such as the International Covenant on Civil and Political Rights (ICCPR). The results of the study show that although the provision of insulting the President in the Criminal Code is only referred to as a complaint offense and is framed to protect the dignity of state institutions, the provision still has the potential to limit freedom of opinion excessively. In addition to risking opening a loophole for criminalization of legitimate public criticism, this rule also has the potential to contradict the principles of non-discrimination and accountability of public officials in a democratic country. Therefore, an in-depth evaluation of the formulation of norms and their application is needed so that they do not conflict with the spirit of democracy and the protection of human rights.   Keywords: , , , , .

This research is motivated by several factors that cause voter behavior in the regional head election in Banjar City. The purpose of this study is to determine voter behavior in the Regional Head Election in Banjar City. The method used in this study is descriptive analysis. There are 7 informants. Data collection techniques are literature studies, field studies (observations and interviews) and documentation. The author uses qualitative data analysis techniques through data processing from interviews and observations to draw conclusions so that they can answer the problems in the study. Based on the results of the study, it is known that: voter behavior in Banjar City is still dominated by the tendency of traditional voters and skeptical voters. This is evidenced by the problem of many voters who determine their choices based on following suit if most of their environment chooses a candidate pair, in addition, voters in determining their political choices are based on information obtained from their parents or from their environment, there are voters who are reluctant and lazy to pay attention to political contestation. There are obstacles to voter behavior in the regional head election in Banjar City, including unequal access to information so that people only get political information from unverified social media. In addition, the practice of money politics is still a reality that is difficult to avoid, where direct assistance or certain promises are the main considerations in choosing candidate pairs as well as past experiences. To overcome various obstacles, a number of efforts have been made, including the Banjar City General Election Commission (KPU) implementing a voter education program through direct outreach to the community, especially in villages and densely populated areas.

Drawing on the participants' concrete lived experiences, this study explores how the processes of typification and we-relations shape the construction of meaning in everyday interactions. Data were collected through in-depth interviews and participant observation with four informants and one single caregiver, and analyzed descriptively texturally and structurally. The findings show that affective communication includes empathy, humor, and firm but authoritative correction that become the foundation for the formation of emotional bonds and a sense of “new family.” Holistic routines (praying in congregation, studying, social activities) facilitate the internalization of religious values, discipline, and independence, which in turn strengthen children's self-identity. The process of meaning construction does not only occur through words, but through daily practices that bring together the emotional, spiritual and social dimensions. These results recommend strengthening intersubjective communication training for caregivers in similar institutions to support the development of character and identity of orphans.

The development of information technology has had a significant impact on the healthcare sector, particularly in improving the efficiency and quality of services. Technologies such as Big Data and the Internet of Things (IoT) enable the collection and analysis of large volumes of medical data as well as real-time patient monitoring. This study aims to analyze how the integration of Big Data and IoT can enhance the quality of healthcare services, with a focus on their impact on patient care and hospital operational efficiency. The research method used is a literature review, involving the collection and analysis of data from various sources such as scientific journals, articles, and related research reports. The results indicate that hospitals that have implemented these technologies have experienced significant improvements in several aspects, including increased diagnostic accuracy, reduced service delays, and more efficient resource management. Real-time patient monitoring through IoT devices enables faster medical decision-making, while Big Data analytics helps predict disease patterns and medical needs. However, the challenges faced include data security issues, infrastructure limitations, and shifts in healthcare practice paradigms. In conclusion, the integration of Big Data and IoT can improve the quality of healthcare services, but addressing the existing challenges is essential to optimize its implementation in the healthcare sector.

The River Basin (DAS) as a place of absorption and water source for living things, forms an ecosystem and a direct relationship between humans and nature. This study aims to determine the function of the Subayang River for the DAS community in Tanjung Belit Village, and to analyze the process of interpreting the river using the social construction theory of Peter L. Berger and Thomas Luckman. This study uses a descriptive qualitative approach, with data collection techniques in the form of in-depth interviews, observation, and documentation. Data analysis uses the Miles and Huberman model. The research subjects numbered eight people, consisting of six main subjects (selected purposively) and two key subjects. The results of the study show that the Subayang River has domestic functions (consumption and MCK) and non-domestic (interaction space, economic function, mobility, culture, conservation, and disposal). The process of the community interpreting the Subayang River consists of three processes, namely externalization (Knowledge) sources of community knowledge about rivers are formed through direct experience, family heritage, social interaction, norms or unwritten rules maintained by the community. Objectivation (Attitude) of Subayang River is not only seen as a water source but as a source of life, as a sacred object, river as identity and river as a place of purification. Internalization (Action) of society carries out various actions that come from the community's response to the river. The social construction process is influenced by internal factors (Personal Experience, Cognitive Awareness, Emotional) and external factors (Family, Norms/Rules, Community Culture, Environmental Conditions).

Optimization of the justification for the establishment of prisoner guidance so far, is based on policies that maintain the types of criminal penalties as regulated in Article 10 of the Criminal Code. Prisoner guidance is one type of sanction in criminal law that is often used as a means to overcome crime problems. The use of prisoner guidance as a means to punish perpetrators of criminal acts began in the late 18th century which was based on the ideology of individualism and the humanitarian movement. Prisoner guidance increasingly plays an important role and shifts the position of the death penalty and corporal punishment which are considered cruel.In general, the image of prison is a very scary place, not getting good food, sleeping on the floor and being bitten by mosquitoes, there is torture and it is very uncomfortable, it is difficult to communicate with the outside world and family, there is no entertainment and suffering and limited in everything. Teguh Prasetyo, explained that prison gives an image to the general public, as a place where criminals are deprived of their freedom and tortured and employed or trained so that they can form good behavior and character after leaving prison. Therefore, the image was changed to prisoner development. The image of prison that gives a scary image to the general public, aims to provide a deterrent element for criminals, so that they become aware and change their evil attitudes and behavior. Based on the background above, the following problem formulation is determined: How to Optimize the Implementation of Prisoner Development in Changing Behavior Towards Inmates?. This research is an empirical legal research, which examines the optimization of the implementation of prisoner guidance in changing the behavior of inmates carried out at the Class III Langkat Youth Penitentiary. The implementation of empirical legal research aims to see the empirical conditions of the optimization of the implementation of prisoner guidance in changing the behavior of inmates at the Class III Langkat Youth Penitentiary, as well as its influence on changes in prisoner behavior.

The coaching system for drug convicts is carried out in correctional institutions, where Correctional Institutions are a form of criminal punishment (imprisonment). In the rehabilitation process, victims of narcotics abuse are not objects but subjects. Criminal punishment (punishment) is not merely giving suffering to deter, but an element of guidance and coaching with the aim that lawbreakers can realize their mistakes and not repeat their actions again, and can return to society and carry out their social functions properly. The purpose of this study was to find out the concept of fostering convicts through rehabilitation, Implementation of Rehabilitation of Narcotics Prisoners in Lubuk Pakam Class II B Prison, Effectiveness of implementing Narcotics Rehabilitation in Lubuk pakam Class II B. This research is included in the descriptive research with the type of empirical juridical research using qualitative analysis methods.From the results of the research it is known that the concept of rehabilitation in the process of coaching prisoners is aimed not only at the mentality of prisoners but also treating dependence on narcotics themselves so that prisoners can recover physically and mentally. Implementation of rehabilitation is based on the provisions of Law Number 35 of 2009 concerning Narcotics and several rules for the implementation of rehabilitation, the Implementation of Fehabilitation in the Class IIB Lubuk Pakam Penitentiary includes medical rehabilitation and social rehabilitation. The implementation of medical rehabilitation includes the Health Examination Stage, the Detoxification Stage, the mental and emotional stability stage of the sufferer. While social rehabilitation includes personality development and independence development and the application of medical rehabilitation and social rehabilitation at the Lubuk Pakam Class IIB Penitentiary is quite effective in reducing the repetition rate (recidivist) of convicts who have completed their sentence, convicts who have served a period of detention have recovered from dependence on narcotics, but the environment outside the prison can affect the re-use by inmates.

Wasting affects health and threatens children potential. Direct factors such as food intake need to be maximized to improve nutritional status. This study aims to determine the differences in energy and macronutrient intake, food parenting, and exclusive breastfeeding history in wasting and non-wasting toddlers in the working area of Sidotopo Wetan Health Center Surabaya. This study is a case control study. Total respondents were 88 toddlers aged 7-60 months, consist 44 wasting toddlers taken with total sampling technique and 44 non-wasting toddlers taken with purposive sampling technique with age and gender matching. Energy intake and macronutrients were obtained by 3x24 hour food recall questionnaire, food parenting patterns obtained from filling out FPSQ (Feeding Practices and Structure Questionnaire) and FPSQ-M (Milk Version) questionnaires, exclusive breastfeeding history obtained through interviews with questionnaires, anthropometric data measured using digital scales and microtoas. Data analysis used independent t-test and Mann Whitney test. The results of this study showed there were significant differences in energy intake (p=0.000), carbohydrates (p=0.023), protein (p=0.000), fat (p=0.000), and exclusive breastfeeding history (p=0.003) and there was no significant difference in food parenting (p=0.632) between wasting and non-wasting toddlers. Parents are expected to pay attention to food intake and provide exclusive breastfeeding.

This study aims to explore the effectiveness of optimal hydration on brain activity and mental health in students and workers through a biopsychological approach. Five participants (three students and two workers) participated in a hydration intervention by drinking at least 8 glasses of water per day for seven days. The design used was a one-group pretest-posttest, with measurements using the PANAS (Positive Affect Negative Affect Schedule) scale and daily reflection. The results showed an increase in positive emotion scores and a decrease in negative emotion scores after the intervention was carried out in both groups. Participants' daily reflections supported these findings, although some experienced discomfort such as bloating or nausea. Biopsychologically, adequate hydration can contribute to cognitive function, emotional control, and daily productivity. This study confirms that regular drinking habits are a simple but effective strategy in improving mental health and brain function in both students and workers.

The method used is a qualitative approach with data collection through in-depth interviews and observations at home, school, and the social environment. The results of the study indicate that family support, positive interactions with peers, and effective teaching methods at school significantly improve children's language skills. The conclusion of this study emphasizes the importance of creating a supportive environment in all aspects to facilitate optimal language development.

Coffee production generates large amounts of solid waste, particularly coffee pulp, which can lead to environmental pollution if not properly managed. This study investigates the utilization of coffee pulp waste as a liquid organic fertilizer (LOF) and its effect on the growth of Arabica coffee seedlings (Coffea arabica L.). The experiment was conducted using a randomized complete block design (RCBD) with five treatments (0, 10, 20, 30, and 40 ml/L of LOF) and five replications. Observations were made on seedling height, stem diameter, and number of leaves over a four-month period. The results showed that the application of LOF had a significant effect on plant height and number of leaves. The highest increase in height and leaf count was observed in the 30 ml/L treatment, while the 40 ml/L treatment showed a slight decline, possibly due to nutrient oversaturation. However, stem diameter did not show a statistically significant difference among treatments. Correlation analysis indicated a strong positive relationship between plant height and leaf number (r = 0.800), suggesting synchronized vegetative growth. These findings demonstrate the potential of coffee pulp LOF as an eco-friendly alternative to chemical fertilizers in coffee seedling nurseries. Further research is recommended to evaluate long-term effects and optimal dosages for different growth stages.

This study aimed to evaluate the effect of chitosan-based liquid organic fertilizer (LOF) at various concentrations on the growth of cocoa seedlings (Theobroma cacao L.). The research was conducted at PTPN I Regional 5, Kendenglembu Plantation, Banyuwangi, for four months using a Completely Randomized Block Design (RCBD) with five treatments: P0 (control), P1 (10 mL/L), P2 (20 mL/L), P3 (30 mL/L), and P4 (40 mL/L). Growth parameters observed included plant height, stem diameter, and number of leaves up to 12 Weeks After Planting (WAP). ANOVA analysis showed no statistically significant effect of the treatments on any parameter. However, descriptive data indicated that concentrations of 20–30 mL/L tended to produce better growth: P2 (31.25 cm) had the highest plant height, P3 (6.93 mm) the highest stem diameter, and P1 (12 leaves) the most leaves. Chitosan potentially acts as a plant growth stimulator by increasing nitrogen availability and enhancing physiological processes such as photosynthesis. In contrast, a high concentration (40 mL/L) exhibited inhibitory effects. Although the differences were not statistically significant, concentrations of 20–30 mL/L could be recommended for practical application. The lack of significant results may be attributed to suboptimal concentrations, application frequency, or environmental conditions. Further studies are recommended to modify treatments and assess additional parameters such as biomass, root development, and leaf area to better understand the efficacy of chitosan fertilizer in cocoa seedling growth.

The 1945 Constitution of the Republic of Indonesia states that every Indonesian citizen has the right to a clean and healthy living environment. Unsustainable development and exploitation of natural resources have led to a drastic decline in the quality of the living environment in Indonesia. This has resulted in environmental damage, such as pollution and loss of biodiversity. One important instrument in the effort to protect the environment is environmental law, which is regulated by Law Number 32 of 2009 concerning the Protection and Management of the Living Environment (Environmental Protection Law). Although the Environmental Protection Law provides a comprehensive legal framework, law enforcement in the field still faces several issues, such as limited resources and low legal awareness. In such situations, community participation can be strategically utilized to enhance the efficiency of environmental monitoring and law enforcement. The aim of this research is to descriptively examine the function of community participation in environmental law enforcement as regulated by the Environmental Protection Law, as well as to analyze how effective and challenging its implementation is.

Digital developments in the financing system for issuing Drug Examination Result Certificates (SKHPN) have had a significant impact on improving administrative governance in the health and legal sectors in Indonesia. This study uses an empirical legal approach with a juridical-sociological method to analyze the use of information technology in payment mechanisms and governance of SKHPN services. Data were collected through in-depth interviews, direct observation, questionnaire distribution, and studies of regulations, including Law Number 17 of 2023 concerning Health and Government Regulation Number 28 of 2024. The findings show that the digitalization process of financing has a positive impact on shortening bureaucratic channels, accelerating service verification, and encouraging budget transparency and accountability. The implementation of an integrated health information system as regulated in Articles 371 to 378 of Law Number 17 of 2023 also strengthens service management through real-time and traceable digital recording. Meanwhile, PP No. 28 of 2024 emphasizes the importance of using electronic payment systems, transparency of financial reporting, and public involvement in service supervision. Although there are still obstacles such as limited infrastructure and low digital literacy, digitalization in SKHPN financing has proven to be a strategic step in realizing adaptive, open and inclusive public services in accordance with the direction of technology-based health policies.

The utilization of Artificial Intelligence (AI) in healthcare services and medical diagnosis in Indonesia has grown rapidly alongside the digital transformation of the health sector. AI technology has been employed to improve service efficiency, accelerate diagnostic processes, and enhance disease detection accuracy, particularly through medical imaging and ECG data analysis. Algorithms such as K-Nearest Neighbor (KNN) and Chi-Square have shown effectiveness in heart disease classification. However, despite its benefits, AI implementation presents legal challenges. The absence of specific regulations regarding legal liability in cases of AI-based diagnostic errors creates uncertainty for both medical professionals and patients. Additionally, the lack of national standards, weak patient data protection, and digital literacy gaps present significant obstacles. Adaptive policies, the establishment of dedicated regulations, and collaboration between government, medical practitioners, technology developers, and academics are essential to develop a legal framework that accommodates AI advancements responsibly. With clear legal certainty, AI technology can be optimally utilized to support more inclusive and high-quality healthcare services.

It is impossible to disentangle customary law from the fabric of a community as it is an integral aspect of society as a whole.  The national legal system in Indonesia also develops as society evolves in response to shifting social, cultural, economic, and political demands.  Through the lens of positive legislation and field practices, this study adopts a juridical-sociological method to better understand how indigenous people's rights are legally protected in environmental management.  By taking a legal stance, we may analyse the constitutional guarantees and statutes that protect indigenous peoples' rights from 1945 forward.  At the same time, the sociological method seeks to understand indigenous populations' experiences with, reactions to, and advocacy for their right to a sustainable environment in light of these legislative obligations.  The 1945 Constitution guarantees, in Article 18B paragraph (2).

Fraud in the buying and selling of projects and jobs is becoming more common and is causing unrest in society. The method used by the wrongdoers often involves making false promises and tricking others to gain personal benefits illegally. This study aims to look into how Article 378 of the Criminal Code applies to a fraud case in the buying and selling of projects and jobs in South Lampung, focusing on the Tanjung Karang District Court decision Number 467/PID.B/2023/PN TJK. The study uses a legal method that focuses on laws and specific case studies. Data were collected through literature reviews and examination of relevant court decisions. According to the discussion results, it is clear that the crime of fraud elements, as described in Article 378 of the Criminal Code, are present in this case. The accused was found to have committed deceit and told a series of lies that caused the victim to suffer financial losses. The court ruled that the accused was guilty and gave a sentence that matched the actions taken. The use of Article 378 of the Criminal Code in this case is seen as appropriate, providing protection for the victim and discouraging the offender. The conclusion of this study is that criminal law can effectively address fraud in the buying and selling of projects and jobs if there is strong evidence and proper legal procedures.
