Abstract:The rights of justice collaborators (JCs) to obtain sentence reductions in murder cases remain inconsistently applied within Indonesia’s criminal justice system. This research addresses three core issues: the normative legal…
legal basis for JC rights, the consistency of judicial decisions in granting those rights, and the necessity for legal reform. Using a normative juridical approach supported by document analysis and expert interviews, the study examines Law No. 31/2014, SEMA No. 4/2011, and recent judicial decisions, including the high-profile cases of Richard Eliezer and Abdul Khoir. Findings reveal that while legal provisions exist, the absence of detailed indicators, formal mechanisms for status determination, and binding multi-institutional coordination leads to implementation gaps. Judicial discretion remains unchecked, resulting in unequal treatment of justice collaborators with similar contributions. The study concludes that a lex specialis law is urgently needed to standardize definitions, evaluation mechanisms, and inter-agency protection schemes. Recommendations include harmonization of technical norms, incorporation of JC recognition in verdicts, and alignment with UNCAC and UNTOC standards. This would strengthen legal certainty, uphold the principle of nulla poena sine lege, and enhance the effectiveness of the criminal justice system in addressing serious crimes through systemic cooperation.
Abstract:This study examines the fulfillment of remission rights for drug offenders in Indonesia following the enactment of Government Regulation No. 99 of 2012, which introduced restrictive provisions inconsistent with the rehabilitative…
ilitative vision of Law No. 12 of 1995. The research problem lies in the normative contradiction between correctional laws oriented toward behavioural reform and derivative regulations that prioritise punitive measures. The study aims to evaluate the implementation of remission regulations and their alignment with principles of justice and human rights. Employing a normative legal research design, it analyses statutes, judicial decisions, doctrines, and comparative law. Findings reveal that remission has shifted from a universal right to a conditional privilege, disproportionately affecting low-level drug offenders, exacerbating prison overcrowding, and weakening legal certainty. The study concludes that policy reform is necessary through individualised assessments, restorative justice integration, independent oversight, and regulatory harmonisation to restore fairness and uphold human rights.

the prevalence of hypertension by utilizing nonpharmacological therapies, such as consuming young coconut water consumption. Therefore, this study aims to evaluate the effect of young coconut water consumption on reducing high blood pressure in menopausal women. A nonrandomized controlled trial study with a pretest-posttest control group design was chosen as the design of this study, which was conducted at the Community Health Center of Pekalongan, East Lampung Regency. A consecutive sampling technique was used to select eligible participants among menopausal women diagnosed with mild and moderate hypertension by medical personnel, totalling 16 treatment groups and 16 control groups. The treatment group was given the intervention of consuming young coconut water 300 ml morning and evening for seven days and taking standard hypertension medication. Meanwhile, the control group took standard hypertension medication. Participants had their blood pressure checked using an aneroid tensimeter before and after treatment. Data were analysed using a paired t-test with a confidence level (α) of 0.05 to prove the treatment effect on blood pressure reduction. The results found that the treatment of drinking young coconut water affected reducing systole blood pressure (p-value 0.016) and diastole (p-value 0.007). The average decrease in systolic and diastolic blood pressure pre and post-treatment was 11.25 mmHg and 9.87 mmHg after participants were controlled by taking standard hypertension medications. Drinking young coconut water can be used as a companion option for hypertension treatment by the community.

Nias Regency. This study aims to determine the level of performance of Sisobahili Village office employees in the use of technology to improve administrative services. This research uses a qualitative approach with a type of descriptive research, and the object of this study is carried out on natural objects. The data collection techniques used in this study are Observation, Documentation, and Interview. The researcher made observations by directly going into the field to see the object being studied. Then the researcher conducted interviews to explore information to data sources, namely the main informant, key informant, and supporting informant, then collected documents about the use of technology techniques in analyzing the data carried out in this study after data collection, then data reduction, data presentation, and conclusion or verification. Based on the results of the research, it was concluded that the Sisobahili Village Office still does not have adequate facilities to support administrative service activities to the community such as computers that are still not owned by the Sisobahili Village office, the facilities in the Sisobahili Village office, only in the form of laptops and printers . The limitations of these facilities are an obstacle for the Village apparatus in carrying out administrative activities related to the use of technology, so in this case information technology has not been used optimally. Human Resources in the use of information technology by the Sisobahili Village apparatus is still low, due to the low level of education of village apparatus in terms of technology utilization, so that some forms of services carried out still have obstacles, all forms of services related to technology are always charged to operators and other devices that are able to use technology, so it can be concluded based on the results of interviews at the level of human resources of the Village apparatus The use of technology is still minimal. The technology application system in Sisobahili Village has been running since 2018, but in 2022-2023, the Village information system, based semi-online, due to a lack of support, and for 2024 the plan will be carried out online through the website.
