Reconstructing Cosmic Harmony: Singer, Indigenous Justice, and the Legal Pluralism of Forest Fire Governance among the Dayak Ngaju
No full textRecurring forest and land fires (Karhutla) in Central Kalimantan reveal not merely an environmental emergency, but a structural failure of Indonesia’s state-centered environmental law to deliver effective and socially legitimate ecological justice. This article critically examines how the Dayak Ngaju customary legal system challenges the dominance of punitive–administrative fire governance through singer sanctions and community-based adjudication, which frame forest fires as violations of collective ecological order rather than isolated criminal acts. Employing a socio-legal approach, the study combines doctrinal analysis of national environmental law with contextual examination of indigenous legal practices to expose the tension between state law and living customary law in the resolution of forest fires. The analysis demonstrates that, while state law prioritizes criminal liability and regulatory compliance, Dayak Ngaju customary law operates through restorative accountability, material compensation, and community responsibility aimed at restoring ecological balance. This article argues that the marginalization of indigenous legal mechanisms is not a neutral administrative choice, but a source of ecological injustice that perpetuates ineffective fire governance. Its central contribution lies in advancing a critical legal pluralism framework that repositions Dayak Ngaju customary law as a legally operative system capable of correcting the limitations of state environmental law. By foregrounding indigenous legal sovereignty as an analytical claim rather than a cultural footnote, this study offers a normative critique of Indonesia’s environmental governance and proposes a more context-sensitive pathway toward ecological justice grounded in legally recognized pluralism
THE EFFECT OF THE SAFE-SPOT PROGRAM ON THE LEVEL OF SAFETY AWARENESS AMONG FACTORY WORKERS AT PT X SEMARANG
No full textThe rising incidence of workplace accidents in Indonesia indicates that the occupational health and safety (OHS) system is not yet optimal. PT X, a botanical extraction manufacturing company, faces complex hazardous conditions requiring a high level of safety awareness among its workers. However, low levels of safety awareness were observed among factory workers. One way to enhance safety awareness is through a proactive educational program called SAFE-SPOT. This study aims to analyze the influence of the SAFE-SPOT program on the level of safety awareness among factory workers at PT X Semarang. This study employed a quasi-experimental design with a pre-test post-test control group. The study population comprised 92 production workers at factory PT X Semarang. A sample of 58 workers was selected through purposive sampling and randomly allocated into two groups of 29 workers each. Data analysis utilized the Mann-Whitney U Test to determine the influence of the SAFE-SPOT program on safety awareness levels post-intervention in the experimental group compared to the non-intervened control group. The results demonstrate that the SAFE-SPOT program significantly improves safety awareness levels among factory workers at PT X Semarang.
 
Comparison of Risk Factors for Priority Non-Communicable Diseases in Bandung Regency Hajj Pilgrims in 2024
No full textThe most common diseases suffered by Indonesian hajj pilgrims are non-communicable diseases (NCDs). To optimize the health istita'ah policy of the Ministry of Religion, further analysis is needed regarding the risk factors for NCDs in hajj pilgrims. This study aims to compare the risk factors for priority NCDs (hypertension and diabetes mellitus) in hajj pilgrims in Bandung Regency. The research design used was a case-control study with secondary data from the Integrated Hajj Computerized System for Health (Siskohatkes). The number of samples was 178 hajj pilgrims for each case and control group. Data analysis was carried out using the logistic regression analysis method. The results showed that age (OR=4.34; 95%CI=1.45-13.02) and comorbidities (OR=7.65; 95%CI=4.59-12.73) were risk factors for hypertension in hajj pilgrims. Age (OR=2.65; 95%CI=1.14-6.15) and comorbidities (OR=7; 95%CI=4.31-11.34) are also risk factors for diabetes mellitus in hajj pilgrims. Hajj pilgrims with a high-risk age category (≥40 years) or comorbidities are at greater risk of experiencing hypertension than diabetes mellitus. Thus, health coaching for hajj pilgrims must include lifestyle modification and education on routine control compliance
ASSOCIATION OF AGE, BLOOD PRESSURE, AND BODY MASS INDEX WITH TOTAL CHOLESTEROL LEVELS AMONG MINING WORKERS
No full textThe purpose of the study was to determine the relation between age, body mass index (BMI), and blood pressure and total cholesterol levels in mining workers in PT Harmoni Panca Utama, Job Site KDA. The cross-sectional design was used and a multiple linear regression was carried out to determine the relationship between the independent variables and the overall cholesterol levels. The analysis showed that age and BMI were significant in influencing the level of total cholesterol (p < 0.001), but the systolic and diastolic blood pressure did not exhibit significant relations. Age was associated with more LDL and total cholesterol deposition because of age-related changes in lipid metabolism, and the excessive body weight (BMI) was associated with dyslipidemia because of visceral fat deposition and dysfunctional lipoprotein metabolism. These results have highlighted the significance of occupational health-serial of monitoring concerning the age and the nutritional status of workers to avoid cardiometabolism complications
THE CONSERVATION NUMBERS IN THE PETRI NET MODEL OF THREE-PHASE TRAFFIC LIGHTS WITH THE NORWEGIAN SYSTEM
No full textThe Petri net model can be used to represent the discrete state behavior structure of traffic light signals. The Petri net model is also capable of presenting three-phase traffic light scheduling synchronization. This study aims to examine the three-phase traffic light Petri net model that implements the Norwegian system. The Petri net model must pass validation and verification tests, including the use of several Place-Invariants, its boundedness property, conservation, coverability for all states, and simulation. The study results indicate that the model complies with all Place-Invariants, meets all required properties, and the simulation is also accurate. Place-Invariants in each phase must include a dummy. The three-phase traffic light Petri net model with the Norwegian system has a conservation number that applies to the model as a whole. The conservation number is an extension of Place-Invariant that only applies partially to the model
PENERAPAN GENERALIZED LINEAR MODEL DALAM MENANGANI OVERDISPERSI PADA DATA PENGANGGURAN DI INDONESIA
No full textUnemployment remains a major problem in Indonesia. In 2023, the open unemployment rate was recorded at 5.32%, or approximately 7.86 million people. Low absorption of productive-age workers and limited job opportunities have led to a potential increase in unemployment in several regions. This situation requires in-depth analysis to reduce the increase in the open unemployment rate. Various socio-economic factors in Indonesia influence the unemployment rate and can be analyzed using the Generalized Linear Model (GLM) framework. Because unemployment data is count data, the approach used is Poisson Regression. This model has the basic assumption of equidispersion, meaning that the variance is equal to the mean. However, observations indicate that the variance is greater than the mean, resulting in overdispersion. To address this, a GLM development with an additional dispersion parameter, namely Poisson Generalized Inverse Gaussian Regression (PGIGR), was used. This model was chosen because it can capture greater data variation and represent factors that influence the unemployment rate. The results of this study indicate that the number of unemployed between provinces in Indonesia is influenced by the variables of Provincial Minimum Wage, GRDP Growth Rate on a Constant Basis, Literacy Rate, and TPAK, with an AIC value of 33,577.45.Pengangguran masih menjadi salah satu persoalan utama di Indonesia. Pada tahun 2023, tingkat pengangguran terbuka tercatat sebesar 5,32% atau sekitar 7,86 juta jiwa. Rendahnya penyerapan tenaga kerja usia produktif serta terbatasnya kesempatan kerja mendorong potensi meningkatnya jumlah pengangguran di sejumlah daerah. Kondisi ini menuntut adanya analisis mendalam guna menekan kenaikan tingkat pengangguran terbuka. Berbagai faktor sosial-ekonomi di Indonesia turut memengaruhi besarnya angka pengangguran dan dapat dianalisis menggunakan kerangka Generalized Linear Model (GLM). Karena data jumlah pengangguran termasuk data hitungan (count data), pendekatan yang digunakan adalah Regresi Poisson. Model ini memiliki asumsi dasar equidispersion, yaitu varians sama dengan mean. Namun, hasil pengamatan menunjukkan bahwa varians lebih besar daripada mean sehingga terjadi masalah overdispersi. Untuk mengatasinya, digunakan pengembangan GLM dengan tambahan parameter dispersi, yakni Regresi Poisson Generalized Inverse Gaussian (PGIGR). Model ini dipilih karena mampu menangkap variasi data yang lebih besar serta merepresentasikan faktor-faktor yang memengaruhi tingkat pengangguran. Hasil penelitian ini mengindikasikan bahwa jumlah pengangguran antarprovinsi di Indonesia dipengaruhi oleh variabel Upah Minimum Provinsi, Laju Pertumbuhan PDRB Atas Dasar Konstan, Angka Melek Huruf, dan TPAK, dengan nilai AIC sebesar 33.577,45
Exploring the Role of Financial Literacy as a Catalyst for Circular Economy Adoption in Rural MSMEs in Indonesia and ASEAN
No full textThis study aims to explore financial literacy as a key catalyst for accelerating the adoption of the circular economy among Micro, Small, and Medium Enterprises (MSMEs) in rural areas of Indonesia and ASEAN countries. Employing a descriptive qualitative approach through a literature review, the research specifically identifies the relationship between the financial literacy levels of MSME owners and their readiness to implement circular economy innovations. Key aspects discussed include financial management understanding, capacity to access alternative funding sources, and challenges in integrating sustainability principles into everyday business practices. The literature review indicates that low financial literacy significantly hinders rural MSMEs' green investment decisions, while enhancing financial literacy is shown to strengthen MSMEs' capacity to effectively and sustainably adopt circular economy practices. The study underscores the importance of financial education strategies and community-based support programs as strategic initiatives that should be reinforced by government policies and multisectoral collaboration to ensure sustainable rural economic development in Indonesia and the ASEAN region
Equipment Efficiency Analysis of Espresso Machine Using the Overall Equipment Effectiveness (OEE) Method and Total Productive Maintenance (TPM) Approach
No full textThis study aims to evaluate the equipment efficiency of a La Marzocco espresso machine at Kopi Anak Monopole Coffee Shop by employing the Overall Equipment Effectiveness (OEE) method and the Total Productive Maintenance (TPM) framework. The analysis measures machine performance through three main OEE components: availability, performance, and quality. A quantitative approach was used by collecting eight months of observational data (December 2024–July 2025), including operational time, downtime, setup duration, and the quantity of both good and defective outputs. Data interpretation involved OEE computation, the Six Big Losses framework, Pareto prioritization, and Fishbone root-cause analysis. Findings indicate that before TPM implementation, the espresso machine achieved an average OEE of 30.25%, dominated by idling and minor stoppages (65.61%). After TPM was applied, the OEE increased to 31.01%, showing measurable improvement in machine reliability and operator awareness. The study highlights that the adoption of TPM principles in small-scale coffee shops can enhance operational discipline and efficiency, offering both theoretical and practical insights for service oriented businesses
Pediatric Submandibular Abscess: Diagnostic Challenges and Comprehensive Management – A Literature Review
No full textSubmandibular abscess in children is a rare deep neck space infection but can be fatal if diagnosis and management are delayed. Most cases (70–85%) originate from odontogenic infections of the mandibular molars, with Staphylococcus aureus and Streptococcus viridans as the predominant pathogens. This article reviews the etiology, early diagnosis, and management of pediatric submandibular abscesses based on recent literature (2020–2025) from Google Scholar, PubMed, and ScienceDirect. Anatomical and immunological differences in children lead to faster infection spread with nonspecific early symptoms; therefore, careful clinical examination and the use of CT scans or ultrasonography are crucial for early diagnosis. Management includes airway stabilization, culture-based broad-spectrum antibiotics, and timely surgical drainage. Multidisciplinary collaboration among dentists, ENT specialists, and pediatric anesthesiologists is essential to reduce morbidity and mortality. Prospective studies are needed to evaluate the effectiveness of minimally invasive approaches and current antibiotic resistance patterns in children. Early diagnosis, rational therapy, and interdisciplinary cooperation remain the key factors in achieving successful outcomes in pediatric submandibular abscess management
The Role of Rumination in University Students’ Mental Health: A Mediation Analysis of Depression and Anxiety
No full textThis study examined the relationship between rumination and mental health among university students by testing the mediating roles of depression and anxiety. Rumination refers to a repetitive and passive focus on negative experiences and emotions that may influence psychological functioning. A quantitative correlational design was employed. A total of 113 students completed the Ruminative Response Scale (RRS), Beck Depression Inventory-II (BDI-II), Beck Anxiety Inventory (BAI), and General Health Questionnaire (GHQ-12). Parallel mediation analysis indicated that rumination significantly predicted depression (β = .6197, p < .001) and anxiety (β = .5830, p < .001). Depression significantly predicted mental health (β = .2893, p = .025), whereas anxiety was not a significant predictor (β = .1186, p = .343). The direct effect of rumination on mental health was not significant (β = −.0940, p = .427), nor was the total effect (β = .1544, p = .098). However, the indirect effect through depression was significant (β = .1793, p = .031; 95% CI [.00464, .0957]), whereas the indirect path through anxiety was not significant (β = .0692, p = .347). These findings indicate that depression fully mediates the relationship between rumination and mental health. Thus, the influence of rumination on students’ mental health primarily operates through increased depressive symptoms
