A Data-Driven Framework for Integrating Decision-Making and Operational Efficiency in Multi-Product Retail: A Case Study with Experimental Evaluation
Get PDFIn today’s highly competitive retail and industrial landscape, multiproduct retail systems face growing challenges due to complex operations, fluctuating demand, and market uncertainty. This paper presents a data-driven framework for optimizing integrated decision-making and enhancing operational efficiency. By utilizing historical transaction data and advanced analytical techniques, the model combines key operational functions—including demand forecasting, inventory management, and resource allocation—to support real- time, data-informed decisions. The approach employs predictive modeling and optimization algorithms to minimize operational costs while maintaining product availability and service level targets. The initial model features five interconnected components: inspection, distribution, disposal, recovery, and retail centers. However, it currently excludes forward logistics, fleet operations, and is limited to a single product and planning period. To address supplier uncertainty, a deterministic equivalent formulation is introduced, relying on the estimation of statistical moments from limited data. Since supplier selection is critical to effective sourcing strategies, improving this process directly enhances supply chain performance. The study highlights that accurately identifying and modeling operational uncertainties is essential for achieving robust and optimal outcomes in retail environments
Optimal Control Application in Mathematical Model of Indonesian Coffee Export Tax
Get PDFCoffee is one of Indonesia's largest non-oil and gas export commodities in the agricultural sector, significantly contributing to the country's export volume each year. Major export destinations include the United States, Egypt, Japan, Spain, and Malaysia. Approximately 67% of Indonesia's coffee production is exported, while the remaining 33% serves domestic demand. To optimize the economic values related to production, demand, export volume, and export tax revenue, a dynamic model was developed, followed by two simulations: one where the government controls with set economic targets and another without target controls on export tax. The model formulation involved estimating equations using the Two-Stage Least Squares (TSLS) method, which served as constraints within the optimal control model. The objective of the discrete dynamic optimal control function is to minimize a quadratic objective function that represents deviations from target values and optimal control levels. Simulations conducted with varying weights on both the control function and without governmental intervention showed that changes in the export tax have limited impact on final outcomes, likely due to the high export tax rate applied. It is recommended that, to achieve export tax values closer to desired targets, the government could consider adjusting export tariff policies by reducing the export tax rate, which would also encourage increased export volume. @font-face {font-family:"Cambria Math"; panose-1:2 4 5 3 5 4 6 3 2 4; mso-font-charset:0; mso-generic-font-family:roman; mso-font-pitch:variable; mso-font-signature:-536870145 1107305727 0 0 415 0;}@font-face {font-family:Calibri; panose-1:2 15 5 2 2 2 4 3 2 4; mso-font-charset:0; mso-generic-font-family:swiss; mso-font-pitch:variable; mso-font-signature:-469750017 -1073732485 9 0 511 0;}@font-face {font-family:Cambria; panose-1:2 4 5 3 5 4 6 3 2 4; mso-font-charset:0; mso-generic-font-family:roman; mso-font-pitch:variable; mso-font-signature:-536870145 1073743103 0 0 415 0;}@font-face {font-family:"Baskerville Old Face"; panose-1:2 2 6 2 8 5 5 2 3 3; mso-font-charset:77; mso-generic-font-family:roman; mso-font-pitch:variable; mso-font-signature:3 0 0 0 1 0;}p.MsoNormal, li.MsoNormal, div.MsoNormal {mso-style-unhide:no; mso-style-qformat:yes; mso-style-parent:""; margin:0cm; mso-pagination:widow-orphan; font-size:10.0pt; font-family:"Times New Roman",serif; mso-fareast-font-family:"Times New Roman"; mso-ansi-language:EN-US;}p.IOP-CS-Abstract, li.IOP-CS-Abstract, div.IOP-CS-Abstract {mso-style-name:IOP-CS-Abstract; mso-style-unhide:no; mso-style-qformat:yes; mso-style-link:"IOP-CS-Abstract Char"; margin-top:0cm; margin-right:0cm; margin-bottom:18.0pt; margin-left:70.9pt; text-align:justify; line-height:107%; mso-pagination:widow-orphan; font-size:11.0pt; font-family:"Cambria",serif; mso-fareast-font-family:Calibri; mso-fareast-theme-font:minor-latin; mso-bidi-font-family:"Times New Roman"; mso-bidi-theme-font:minor-bidi; mso-font-kerning:1.0pt; mso-ligatures:standardcontextual; mso-ansi-language:EN-GB;}span.IOP-CS-AbstractChar {mso-style-name:"IOP-CS-Abstract Char"; mso-style-unhide:no; mso-style-locked:yes; mso-style-link:IOP-CS-Abstract; mso-ansi-font-size:11.0pt; mso-bidi-font-size:11.0pt; font-family:"Cambria",serif; mso-ascii-font-family:Cambria; mso-fareast-font-family:Calibri; mso-fareast-theme-font:minor-latin; mso-hansi-font-family:Cambria; mso-bidi-font-family:"Times New Roman"; mso-bidi-theme-font:minor-bidi; mso-font-kerning:1.0pt; mso-ligatures:standardcontextual; mso-ansi-language:EN-GB;}.MsoChpDefault {mso-style-type:export-only; mso-default-props:yes; font-size:10.0pt; mso-ansi-font-size:10.0pt; mso-bidi-font-size:10.0pt; mso-font-kerning:0pt; mso-ligatures:none; mso-ansi-language:EN-US;}div.WordSection1 {page:WordSection1;
Hamming Weight-Based Simulation of Correlation Power Analysis for AES Key Extraction
Get PDFThis study investigates the effectiveness of Correlation Power Analysis (CPA) using the Hamming Weight model to extract AES encryption keys in a fully software-simulated environment. By leveraging Python programming, we emulate power traces not from hardware devices but through Hamming Weight calculations derived from byte-level operations during AES encryption. Simulated plaintexts are randomly generated, and key hypotheses are evaluated using Pearson correlation between expected bit-switching activity and simulated traces. The method achieved approximately 50% accuracy with just 10 plaintexts and up to 85% accuracy when using over 1,000 simulated inputs. Correlation coefficients above 0.90 were consistently observed for most key bytes. While the simulation avoids the complexity of real-world noise and hardware interference, it also lacks authentic electrical characteristics. This highlights both the novelty and the limitation of a software-only CPA framework. The findings underline the vulnerability of AES to side-channel attacks and suggest countermeasures like masking to reduce risk

IMPLEMENTATION OF POLICY NO. 46 OF 2023 ON THE PREVENTION AND HANDLING OF VIOLENCE IN KINDERGARTENS IN PIDIE REGENCY
Get PDFCases of violence and bullying within educational settings in Indonesia have become a serious issue, with 2,355 recorded violations of child protection in the education sector as of August 2023. Bullying most frequently occurred at the elementary and junior high school levels (25% each), followed by senior high schools and vocational schools (18.75% each), Islamic junior high schools (6.25%), and Islamic boarding schools (6.25%). Specifically, Aceh Province has also reported a significant number of bullying and sexual violence cases, with 575 cases of sexual violence against women and children recorded by June 2023. In response to the widespread prevalence of harassment cases in Indonesia, particularly in Pidie District, the Ministry of Education issued Regulation No. 46 of 2023 concerning the Prevention and Handling of Violence in Educational Settings. This regulation aims to create a safe and effective learning environment, one of its key measures being the establishment of a Team for the Prevention and Handling of Violence (TPPK) in every educational institution. However, the implementation of this regulation still faces challenges, especially in Pidie District. Observations indicate that the formation of TPPK has not been optimal, particularly at the kindergarten to junior high school levels, whereas senior and vocational high schools—under provincial government authority—have demonstrated more efficient implementation. Although there have been previous studies discussing the prevention and handling of violence in educational environments—whether related to Regulation No. 46 of 2023 or efforts to prevent bullying through character education—these studies tend to focus on narrow scopes. Therefore, this study specifically examines “The Implementation of Regulation No. 46 of 2023 on the Prevention and Handling of Violence in Kindergartens in Pidie District.” This research is crucial for assessing the effectiveness of policy implementation on a broader scale and for emphasizing the importance of early prevention, considering that violent and bullying behavior is often part of a long-term patter

The cultural elements in the museum, such as colonial architecture and a collection of artifacts reflecting the lives of prisoners, successfully create a deep and meaningful learning experience. This study concludes that the museum has an important role in building historical awareness and cultural identity of the Malang community
Implikasi Yuridis Ketentuan Pencatatan Perkawinan Siri Dalam UU No. 1 Tahun 1974 Terhadap Status Keperdataan Istri Dan Anak (Analisis Putusan MK NO. 46/PUU-VIII/2010)
Get PDFABSTRACKMarriage registration as stipulated in Article 2 paragraph (2) of Law Number 1 of 1974 on Marriage is a formal requirement for a marriage to be legally recognized by the state and to produce civil legal consequences. In practice, unregistered marriages, known as siri marriages—those conducted according to religious norms but not officially recorded—remain prevalent in Indonesia. These types of marriages raise significant legal issues, particularly regarding the civil status of the wife and child. The wife in a siri marriage is not legally protected in terms of her marital rights, while the child often has legal ties only to the mother and her family. This research aims to examine the legal implications of the registration requirement on the civil status of wives and children in siri marriages, and to analyze the impact of Constitutional Court Decision Number 46/PUU-VIII/2010 on the legal status of children born outside of officially recognized marriages. The method used is normative juridical research with a statute approach and a conceptual approach. The findings show that while the Court's decision grants civil recognition to children based on biological evidence, the legal position of wives in siri marriages remains unprotected. Legal reform is urgently needed to ensure justice and legal certainty for women and children.Keywords: Juridical Implications, Registration, Unregistered Marriage ABSTRAKPencatatan perkawinan sebagaimana diatur dalam Pasal 2 ayat (2) Undang-Undang Nomor 1 Tahun 1974 tentang Perkawinan merupakan syarat formal agar suatu perkawinan sah secara hukum negara dan menimbulkan akibat hukum keperdataan. Dalam praktiknya, masih banyak terjadi perkawinan siri, yaitu perkawinan yang sah secara agama tetapi tidak dicatatkan pada instansi resmi. Perkawinan siri menimbulkan persoalan hukum serius, terutama terhadap status keperdataan istri dan anak. Istri tidak memperoleh perlindungan hukum atas hak-haknya dalam perkawinan, sedangkan anak yang dilahirkan dari hubungan tersebut kerap kali hanya memiliki hubungan hukum dengan ibu dan keluarganya. Penelitian ini bertujuan untuk mengkaji implikasi yuridis ketentuan pencatatan perkawinan terhadap status keperdataan istri dan anak dalam perkawinan siri, serta menganalisis pengaruh Putusan Mahkamah Konstitusi Nomor 46/PUU-VIII/2010 terhadap perubahan status hukum anak luar kawin. Metode yang digunakan adalah penelitian yuridis normatif dengan pendekatan perundang-undangan (statute approach) dan pendekatan konseptual (conceptual approach). Hasil penelitian menunjukkan bahwa meskipun Putusan MK telah memberikan pengakuan hukum terhadap anak luar kawin yang dapat dibuktikan hubungan biologisnya dengan ayah, posisi hukum istri dalam perkawinan siri masih belum mendapatkan pengakuan yang memadai. Diperlukan pembaruan hukum dan instrumen pelindung yang lebih adil bagi perempuan dan anak dalam sistem hukum nasional.Kata kunci: Impilikasi Yuridis, Pencatatan, Perkawinan Siri, Keperdataan Istri dan Anak
Kaidah Yang Berkaitan Dengan Khulu’
Get PDFKhulu’ merupakan salah satu bentuk pemutusan hubungan pernikahan yang dilakukan atas permintaan istri dengan memberikan kompensasi tertentu (’iwad) kepada suami sebagai imbalan atas talak. Penelitian ini bertujuan untuk menganalisis kaidah khulu’ secara normatif, dan menganalisis dalil dalil nya , serta menelaah implementasinya dalam kehidupan sehari hari, dan juga dalam sistem hukum di Indonesia. Penelitian ini menggunakan pendekatan normatif, dengan studi pustaka terhadap kitab-kitab fikih klasik dan regulasi nasional. Hasil kajian menunjukkan bahwa khulu’ berlandaskan prinsip kerelaan, kejelasan bentuk dan nilai tebusan, serta perlindungan terhadap hak perempuan. Teori khulu’ juga menempatkan suami sebagai pihak yang mengakui akad dan menerima tebusan, sehingga menghasilkan talak ba’in yang tidak dapat dirujuk kecuali dengan akad baru. Studi ini menegaskan bahwa pengaturan khulu’ perlu memperhatikan prinsip keadilan, maqāṣid al-sharī‘ah, serta kepastian hukum bagi kedua belah pihak
