Introduction: Additive Manufacturing (AM) has revolutionized the production of complex geometries, offering flexibility, customization, and precision across various industries. However, optimizing multiple process parameters simultaneously to enhance AM performance remains a significant challenge. This study focuses on improving both mechanical properties and surface quality by utilizing multi-objective optimization techniques. Literature Review: The research reviews existing approaches in AM optimization, highlighting the limitations of single-objective optimization and the potential of multi-objective evolutionary algorithms (MOEAs). Previous studies demonstrate the difficulty of balancing competing objectives, such as tensile strength and surface roughness, within AM processes. Materials and Method: This study employs NSGA-II, MOEA/D, and SPEA2 algorithms to optimize AM parameters like layer thickness, build orientation, and infill density. The optimization aims to improve mechanical performance, including tensile strength and impact resistance, while reducing build time and surface roughness. The methodology integrates experimental validation with computational predictions to evaluate the effectiveness of these algorithms. Results and Discussion: The optimization process yielded Pareto-optimal solutions that balanced mechanical strength and surface quality. The results demonstrated improvements in tensile strength and surface finish without significantly increasing build time. Trade-off analysis highlighted the inherent conflicts between mechanical performance and surface quality, allowing for better decision-making in industrial applications. The study contributes to the AM industry by offering a comprehensive optimization framework for improving both efficiency and product quality.

This study analyzes the politics of spatial planning in the land-use conversion of the Bowosie Forest in Labuan Bajo as part of the National Strategic Project (PSN) for tourism development. The transformation of the forest into an economic tourism zone demonstrates that spatial planning is not neutral, but rather an arena of power relations among the state, investors, and local communities. Through regulatory instruments such as revisions of the Regional Spatial Plan (RTRW), ministerial decrees on forest release, and the granting of Management Rights (HPL) to BPOLBF, the state has facilitated tourism investment and the commodification of space. Using a qualitative approach and David Harvey’s theory of Accumulation by Dispossession, the study finds that these policies have produced three forms of exclusion: spatial exclusion (loss of access to land and water sources), political exclusion (limited community participation in decision-making), and economic exclusion (development benefits concentrated among investors). The village government occupies a structurally limited position due to the top-down nature of the policy framework. The study concludes that the conversion of the Bowosie Forest reflects a process of capital accumulation legalized through state regulation, highlighting the need for more inclusive and socially just spatial planning.

Population mobility is a dynamic phenomenon that plays an important role in regional development processes. Population movement is influenced by various interconnected factors, particularly social, economic, and environmental aspects. This study aims to analyze the factors influencing population mobility using a Systematic Literature Review (SLR) approach. Data were collected from relevant national and international scientific literature published within the last ten years. The results indicate that economic factors are the primary determinants driving population mobility, particularly in relation to employment opportunities and income improvement. Meanwhile, social factors such as education and social networks act as supporting elements in the mobility process. Environmental factors also show significant influence, especially in the context of climate change, natural disasters, and environmental degradation. The interaction among these factors demonstrates that population mobility is a multidimensional phenomenon that requires a comprehensive analytical approach. This study is expected to contribute to the development of population studies and serve as a reference for sustainable development policy formulation.

Penelitian ini menganalisis praktik akuntansi keberlanjutan pada Arif Barbershop, sebuah usaha mikro, kecil, dan menengah (UMKM) di Jombang, Jawa Timur, Indonesia. Dengan menggunakan pendekatan studi kasus kualitatif, penelitian ini mengeksplorasi bagaimana barbershop menerapkan prinsip Environmental, Social, dan Governance (ESG) dalam operasional sehari-hari. Data dikumpulkan melalui wawancara mendalam dengan pemilik usaha dan dianalisis menggunakan analisis tematik. Temuan menunjukkan bahwa Arif Barbershop telah menerapkan praktik lingkungan dasar seperti pengelolaan limbah rambut melalui kantong plastik ke tempat pembuangan sampah, serta efisiensi energi dengan mematikan peralatan listrik setelah jam operasional.

Praktik tata kelola, meskipun bersifat informal, mencakup pencatatan keuangan sederhana menggunakan buku biasa. Namun demikian, barbershop belum memiliki izin usaha formal dan belum menerapkan kerangka akuntansi keberlanjutan yang terstandar. Penelitian ini menyoroti bahwa UMKM dapat mempraktikkan akuntansi keberlanjutan secara intuitif, dan menyarankan perlunya program pelatihan serta alat pelaporan yang disederhanakan.

Penelitian ini mengeksplorasi fenomena kecurangan pada PT Dana Syariah Indonesia (DSI) melalui pisau analisis Fraud Triangle milik Donald R. Cressey (1953). Fenomena penyimpangan di PT Dana Syariah Indonesia (DSI) tercatat sebagai skandal keuangan paling masif pada sektor P2P lending berbasis syariah di tanah air. Sepanjang tahun 2018 hingga 2025, kerugian finansial yang ditimbulkan diestimasi menyentuh Rp2,4 triliun dengan total korban mencapai lebih dari 15.000 pemberi dana. Penelitian ini menggunakan metode kualitatif deskriptif dengan pendekatan studi kasus. Data dikumpulkan melalui studi dokumentasi dari berbagai sumber, meliputi laporan resmi OJK, siaran pers Bareskrim Polri, temuan PPATK, serta publikasi berita terverifikasi. Hasil penelitian menunjukkan bahwa ketiga elemen Fraud Triangle terbukti hadir dalam kasus DSI: (1) Tekanan (pressure) berupa kebutuhan likuiditas internal dan target imbal hasil tinggi 16–18% per tahun yang tidak realistis; (2) Kesempatan (opportunity) berupa lemahnya pengawasan OJK terhadap fintech syariah, ketiadaan audit independen yang efektif, dan eksploitasi kepercayaan berbasis label syariah; serta (3) Rasionalisasi (rationalization) berupa pembenaran pelaku dengan menggunakan argumen ekonomi makro dan penyalahgunaan nilai-nilai syariah sebagai perisai. Penelitian ini juga mengintegrasikan perspektif akuntansi forensik sebagai alat deteksi dan pencegahan fraud. Temuan penelitian ini diharapkan menjadi kontribusi ilmiah bagi penguatan regulasi, pengawasan fintech syariah, serta literasi keuangan masyarakat.

The issue of nutrition among school children remains a public health challenge in Indonesia. As an effort to improve the nutritional status of students, the government launched the Free Nutritious Meal program (MBG) in educational units. However, in its implementation, there are still students who do not take advantage of the program. This study aims to identify the reasons why students do not utilize the Free Nutritious Meal (MBG) program based on the (ABC) theory of antecedent, behavior, consequence at SD Negeri 100 Kendari. This research uses a qualitative method with a case study approach. The number of informants to be studied is 6 people selected through Purposive Sampling, consisting of students, the principal, teachers, SPPG officers, and parents. Data collection is conducted through in-depth interviews, recording, observation, and documentation. The data are analyzed through the stages of data reduction, data presentation, and drawing conclusions. Research results show that the antecedent of students' knowledge about the MBG program is at the level of knowing to understanding, the application of the provided menu has been in accordance with balanced nutrition principles, and the program policy is supported by various parties. Students' behavior shows rejection of the program influenced by negative experiences, perceptions of the halalness of food containers, and parental prohibitions. The consequence of students not participating does not directly have a negative impact on their learning conditions or physical health, because nutritional needs are still met from other sources. Therefore, students have no motivation to utilize the program. In conclusion, students who do not take advantage of the MBG program are influenced by perceptions, experiences, and parental restrictions. Therefore, it is necessary to improve education, strengthen communication, and enhance the quality of program implementation to increase the utilization of the MBG program.

Studi ini dirancang untuk menginvestigasi pengaruh Suhu Permukaan Laut (SST) dan konsentrasi klorofil-a terhadap variabilitas hasil tangkapan ikan di kawasan Pantai Selatan melalui pendekatan model regresi linear berganda dengan estimasi Ordinary Least Squares (OLS). Pada tahap diagnostik awal, terdeteksi adanya indikasi autokorelasi positif pada residual model (statistik Durbin–Watson = 0,993), suatu kondisi yang berpotensi menginduksi bias pada estimasi standard error sehingga dapat mengkompromikan validitas inferensi statistik. Guna mengantisipasi permasalahan tersebut, dilakukan koreksi menggunakan metode Newey-West Heteroskedasticity and Autocorrelation Consistent (HAC) standard errors yang diimplementasikan melalui komputasi Python. Hasil estimasi pasca-koreksi mengungkapkan bahwa secara simultan, variabel SST dan klorofil-a memberikan pengaruh yang signifikan terhadap keragaman hasil tangkapan ikan, dengan nilai koefisien determinasi (R²) sebesar 23,7%. Berdasarkan uji parsial (uji t terkoreksi), SST menunjukkan pengaruh negatif yang signifikan secara statistik terhadap hasil tangkapan, sementara klorofil-a tidak memperlihatkan pengaruh yang signifikan. Temuan tersebut mengimplikasikan bahwa variabel termal (SST) memiliki kontribusi yang lebih dominan dibandingkan indikator produktivitas primer (klorofil-a) dalam memengaruhi dinamika hasil tangkapan ikan pada wilayah kajian.

Social interaction is an important part of students' lives, especially in the school environment and socializing with peers. In the process of this interaction, verbal bullying behavior often appears which is often considered a form of joke or a natural thing. In fact, verbal bullying can have a quite serious psychological impact on students who experience it. This study aims to examine various forms of verbal bullying that occur in social interactions in students and analyze the psychological impact it causes. This study uses a literature review method by analyzing various scientific sources in the form of research journals, scientific articles, and relevant books published in the range of 2016–2026. The results of the study show that verbal bullying in students can appear in various forms, such as mockery of physical or ability, insults, the use of harsh words, yelling, and humiliation in front of others or the general public. Various studies have also shown that these behaviors are influenced by the factors of the friendship environment, lack of emotional control, and excessive joke culture among students. The psychological impact caused includes decreased self-confidence, the emergence of feelings of sadness, anxiety, stress, and a tendency to withdraw from the social environment. Therefore, attention from various parties, especially the school and family environment, is needed to prevent and reduce the occurrence of verbal bullying so that students' psychological development can take place in a healthy manner.

This study aims to analyze the impact of middlemen on the price of Fresh Fruit Bunches (FFB) of oil palm received by farmers in Lambur I Village, Tanjung Jabung Timur Regency, from a sharia economic perspective. This study also examines the FFB marketing patterns carried out by farmers and the factors that influence farmers in choosing where to sell their harvest. The method used is a qualitative approach with a case study research type. Data were obtained through in-depth interviews, field observations, and documentation to understand FFB marketing practices and the socio-economic relationships between farmers and middlemen. The results show that FFB marketing in Lambur I Village is carried out through three main channels: middlemen, the Marketing Chain of Trust (RAM), and palm oil processing factories. Most farmers choose to sell FFB to middlemen because the transaction process is easier, payments are fast, and transportation costs are not required. In addition, urgent financial needs, limited transportation facilities, and long-standing socio-economic relationships also influence farmers' dependence on middlemen. In practice, middlemen play a dominant role in determining prices, deducting approximately Rp 250–Rp 300 per kilogram from the factory price. From a sharia economic perspective, marketing practices through middlemen are essentially permissible as long as they are carried out with mutual consent and do not contain elements of usury, gharar, or injustice. However, the dominance of middlemen in determining prices indicates a bargaining imbalance that could potentially harm farmers, thus not fully reflecting the principle of justice in sharia economics

Pengelolaan anggaran daerah memerlukan sistem pengendalian internal yang efektif serta penerapan manajemen risiko yang terintegrasi untuk mendukung tercapainya tujuan pembangunan secara optimal. Namun, pada praktiknya masih banyak pemerintah daerah menghadapi persoalan berupa rendahnya kualitas perencanaan, lemahnya pengawasan, ketidaktepatan prioritas belanja, serta belum optimalnya pemanfaatan sumber daya fiskal. Penelitian terdahulu umumnya membahas pengendalian internal dan manajemen risiko secara terpisah, sedangkan kajian mengenai sinergi keduanya dalam pengelolaan anggaran daerah, khususnya pada daerah dengan kapasitas fiskal terbatas, masih relatif terbatas. Penelitian ini bertujuan untuk menganalisis sinergi antara internal control dan manajemen risiko dalam pengelolaan anggaran pada Pemerintah Kabupaten Bengkulu Tengah. Penelitian dilakukan dengan metode kualitatif melalui wawancara mendalam, observasi, dan telaah dokumen, kemudian dianalisis menggunakan model interaktif Miles dan Huberman. Hasil penelitian menunjukkan bahwa internal control telah berjalan secara normatif melalui fungsi pengawasan APIP. Namun, penerapan manajemen risiko masih bersifat administratif dan belum menjadi dasar utama dalam pengambilan keputusan anggaran. Temuan ini menunjukkan kebaruan bahwa integrasi pengawasan internal berbasis risiko menjadi model penting dalam meningkatkan efektivitas, efisiensi, akuntabilitas, dan kualitas tata kelola keuangan daerah.
