A NEW APPROACH TO BOUNDING THE PERIMETER OF AN ELLIPSE: EXTREMAL ANALYSIS AND INTEGRAL REFORMULATION
Get PDFThe perimeter of an ellipse is typically represented using an elliptic integral, which does not have a closed-form solution. One common approach to approximating the ellipse perimeter involves determining its bounds using arithmetic, geometric, and harmonic means. This study refines the integral formulation representing the ellipse perimeter as the average of its integral. By restructuring the integration limits, a new method is introduced to determine the bounds based on the extreme values of the integrand. This approach offers a clearer geometric interpretation, establishes new lower and upper bounds for the perimeter, and proposes a conjecture for the greatest possible lower bound, supported by analysis of the trapezoidal rule with a single subinterval

No full textThis editorial explores the paradigm shift in Indonesian public policy over the past two decades, driven by the dual forces of digital transformation and decentralization. These changes have reshaped public administration, the relationship between the state and citizens, and intergovernmental dynamics. Digital transformation fosters data-driven, responsive, and transparent governance, while decentralization enables local governments to craft policies suited to local needs. The May 2025 edition of the Journal of Public Policy and Management Inquiry presents articles addressing issues such as poverty data accuracy, digital banking service quality, youth involvement in cultural preservation, mining policy implementation in South Papua, rural digitalization efforts in West Java, civic engagement via social media, Indonesia-Australia economic cooperation, and regional financial governance. Together, these perspectives underscore the importance of inclusive, adaptive, and data-based policy reforms, emphasizing the critical role of citizen participation and cross-level accountability in shaping public policy in the digital era

Rent-Seeking Theory in the Asymmetry of Blue Economy Benefit Distribution: Economic and Sustainability Accounting Perspectives
Get PDFThe blue economy offers great potential for growth, but the unequal distribution of benefits creates serious inequalities. This research explores the impact of unequal access to marine resources, particularly for small-scale fishers and indigenous communities, through the lens of rent-seeking theory and sustainability accounting. The privatization of coastal resources often enriches large corporations while marginalizing local communities, undermining food security and leading to human rights violations. In addition, renewable energy projects in coastal areas reflect a disregard for social and ecological values that exacerbate resource conflicts. The analysis shows that top-down governance widens the gap, while traditional reporting fails to capture the social and environmental externalities of resource exploitation. The study highlights the importance of Social Return on Investment (SROI)-based reporting approaches and environmental cost-based accounting to measure the holistic impact of blue economy policies. The marginalization of women in the fisheries sector, which is often not recognized in formal reporting, underscores the need for gender-based accounting. As a solution, genuine, not just symbolic, participation of local communities must be integrated in inclusive governance. Reporting approaches such as Integrated Reporting and the Global Reporting Initiative (GRI) can map economic, social and ecological dimensions in a more balanced way. With strengthened accountability and a comprehensive sustainability framework, the blue economy has the potential to be a tool for equitable growth, protecting the rights of local communities while keeping ecosystems in balanceEkonomi biru menawarkan potensi besar untuk pertumbuhan, tetapi distribusi manfaat yang tidak merata menciptakan ketimpangan serius. Penelitian ini mengupas dampak ketidakadilan akses terhadap sumber daya laut, khususnya bagi nelayan kecil dan masyarakat adat, melalui lensa teori rent-seeking dan akuntansi keberlanjutan. Privatisasi sumber daya pesisir sering kali memperkaya korporasi besar sembari meminggirkan komunitas lokal, merusak ketahanan pangan, serta memunculkan pelanggaran hak asasi manusia. Selain itu, proyek energi terbarukan di wilayah pesisir mencerminkan pengabaian terhadap nilai sosial dan ekologis yang memperburuk konflik sumber daya. Analisis menunjukkan bahwa tata kelola top-down memperlebar kesenjangan, sementara pelaporan tradisional gagal mencatat eksternalitas sosial dan lingkungan dari eksploitasi sumber daya. Studi ini menyoroti pentingnya pendekatan pelaporan berbasis Social Return on Investment (SROI) dan akuntansi berbasis biaya lingkungan untuk mengukur dampak holistik kebijakan ekonomi biru. Marginalisasi perempuan dalam sektor perikanan, yang sering kali tidak diakui dalam pelaporan formal, menggarisbawahi perlunya akuntansi berbasis gender. Sebagai solusi, partisipasi masyarakat lokal yang sejati, bukan hanya simbolis, harus diintegrasikan dalam tata kelola inklusif. Pendekatan pelaporan seperti Integrated Reporting dan Global Reporting Initiative (GRI) dapat memetakan dimensi ekonomi, sosial, dan ekologi secara lebih seimbang. Dengan akuntabilitas yang diperkuat dan kerangka keberlanjutan komprehensif, ekonomi biru berpotensi menjadi alat pertumbuhan yang adil, melindungi hak-hak masyarakat lokal sekaligus menjaga keseimbangan ekosistem

HUBUNGAN TINGKAT STRES DENGAN PERILAKU MAKAN MAHASISWA DI INDONESIA
Get PDFMental health in students can be caused by academic stress. Academic stress is a pressure that occurs caused by competition or academic demands. Students who feel stressed can experience troubled appetites. Experiencing stress will cause the release of hormones that affect eating behavior. When someone experiences stress, they tend to have unhealthy behaviors such as eating too little, overeating, eating fatty foods, or eating foods with excessive sugar. The study applied a quantitative approach using a cross-sectional design. Data collection was done through distributing a questionnaire to Indonesian students totaling 180 students as respondents. The results of the study showed a relationship between stress and 6 categories of eating behavior (low-fat eating, emotional eating, sweet snacking, cultural/environmental/healthy eating behavior, meal planning, and skipping meals). The Spearman correlation test showed a significant relationship in the category of emotional eating (p-value = 0.0001, r = 0.2874), cultural//environmental/healthy eating behavior (p-value 0.0476, r = -0.1479, skipping meals (p-value = 0.0001, r = 0.2856), in contrast, there was an insignificant relationship in the category of low-fat foods (p-value = 0.9977, r = - 0.0002), sweet snacking (p-value = 0.1625, r = 0.1045), and meal planning (p-value = 0.9051, r = 0.0090)

These results indicate a significant decrease in cholesterol levels (p < 0.005) of BALB/C mice. In addition, mice fed a high-fat diet experienced a decrease in total cholesterol levels after receiving kaffir lime peel ethanol extract treatment
PENGARUH KOMBINASI SORGUM DAN KACANG TUNGGAK TERFERMENTASI TERHADAP SIFAT FISIK DAN ORGANOLEPTIK SERBUK MINUMAN SEREALIA
Get PDFStunting caused by malnutrition from the prenatal period to the age of two can cause various short-term and long-term health problems. One solution to prevent malnutrition is providing additional food (PMT) from local ingredients. Therefore, this study utilized sorghum and cowpeas, which are high in carbohydrates and protein and are expected to prevent malnutrition in pregnant women and toddlers. Additionally, they maximize local food ingredients such as cereal drink powder. This study aimed to determine the effect of the combination of sorghum and cowpeas on the physical and organoleptic characteristics of cereal drink powder. This study used a Completely Randomized Design (CRD) with the addition of sorghum and cowpea at concentrations of 15%: 15%, 20%: 10%, and 25%: 5%, with two repetitions, each in duplicate. Data were analyzed using one-way ANOVA at a 5% significance level, and if significant differences were found, DMRT was used for further analysis. The results showed that the concentration of sorghum and cowpeas had a significant effect (p<0.05) on viscosity, rehydration time, color, and organoleptic attributes (taste, thickness, and overall). However, the concentration did not have a significant effect (p>0.05) on hygroscopicity rate, hygroscopicity level, solubility, and organoleptic attributes (color and aroma)
