Abstract

This study evaluates the quality and visitor satisfaction across Anyer Beach, Tanjung Lesung Beach, Carita Beach, and Sawarna Beach in Banten, Indonesia, using the Bath Area Registration and Evaluation (BARE) survey and Importance-Performance (I-P) Matrix analysis. Each beach's attributes, including security, water quality, facilities, litter management, and scenery, are assessed to identify strengths and areas for improvement. The findings reveal varying levels of performance and visitor satisfaction, highlighting notable gaps in safety, medical facilities, showers, waste facilities, and changing rooms. Recommendations include enhancing safety measures, upgrading medical and shower facilities, improving waste management practices, and preserving scenic beauty to enhance visitor experiences and support sustainable tourism practices.

Abstract

Penelitian ini bertujuan untuk mengembangkan sebuah Sistem Pendukung Keputusan (SPK) yang digunakan dalam menentukan Sekolah Menengah Pertama berprestasi di wilayah Kabupaten Serang, Provinsi Banten. Pengembangan SPK ini diharapkan mampu membantu pihak terkait, seperti dinas pendidikan atau pengawas sekolah, dalam melakukan proses penilaian sekolah secara lebih sistematis, objektif, dan terstruktur. Dengan adanya sistem ini, proses evaluasi sekolah dapat dilakukan dengan lebih mudah dan cepat tanpa harus melakukan kunjungan langsung ke setiap sekolah, sehingga lebih efisien dari segi waktu dan biaya. Metode yang diterapkan dalam penelitian ini adalah Simple Additive Weighting (SAW), yang dipilih karena mampu memberikan perhitungan berdasarkan pembobotan kriteria secara jelas dan terukur. Pengumpulan data dilakukan melalui wawancara dengan pengawas sekolah sebagai sumber data primer, serta observasi data sekolah yang diperoleh dari Dapodik dan dokumentasi sebagai data sekunder. Hasil penelitian menunjukkan bahwa metode SAW mampu menghasilkan penilaian yang akurat dan efisien, di mana Sekolah Menengah Pertama Terpadu Bismilah menempati peringkat tertinggi sebagai sekolah berprestasi. Kesimpulannya, penerapan SPK ini dapat meningkatkan kualitas pengambilan keputusan dalam penilaian sekolah berprestasi di Kabupaten Serang.

Abstract

This paper introduces a hagoslot stochastic model to investigate the failure times of bearings based on a two-parameter Weibull distribution utilizing Monte Carlo simulation. The failure times were fitted based on maximum likelihood estimation, and the parameters showed that the wear-out failure type with an increasing hazard rate (β>1) was corresponding to the fatigue-induced breakdown phenomenon in the rolling bearings. A Monte Carlo simulation with 1000 runs was performed to quantify the uncertainty of lifetime predictions, which have presented relatively high spreads but stable central tendencies in the Weibull parameter estimates. Survival analysis and hazard function showed increasing probability of failure with time, indicative of the need for prognosis-based maintenance. The findings demonstrate that the Weibull model is a reliable and interpretable paradigm that can be used to describe the probabilistic nature of mechanical component failure. The presented modeling strategy is appropriate for both engineering purposes and simulation-based reliability analyses, possibly evolved into a mixture-Weibull representation or data-driven parameter estimation.

Abstract

This study models the health service queue system at the Integrated Health Service Post (Posyandu) in Cilegon City, Banten, using the Petri Net and Max-Plus Algebra approaches to analyze the flow of participant arrivals and completion times. The data used are observational data from Posyandu activities simulated through a discrete event model, which includes several types of participants, namely: babies not standing yet, babies standing, pregnant mothers, and family planning programs. Petri Net modeling is used to represent the relationship between service transitions, while Max-Plus Algebra is used to calculate the process cycle time based on the critical path. The results of the study showed that the categories of non-standing babies, standing babies, and pregnant women/participants in the family planning program had identical service time patterns, namely a total duration of 17 minutes 19 seconds, with the main stages including measurement, midwife intervention, and provision of additional food. Max-Plus analysis confirms that the measurement and midwife intervention stages are the critical path that determines the length of service time. This study concludes that the combination of Petri Net and Max-Plus Algebra is effective in describing the dynamics of Posyandu queues and is able to provide quantitative information needed to identify bottleneck points and the basis for improving the service flow.

Abstract

A Foreign exchange reserves are a vital instrument in maintaining Indonesia's macroeconomic stability, particularly in mitigating external turmoil and stabilizing the rupiah exchange rate. This study aims to analyze the factors that affect Indonesia's foreign exchange reserves position for the period from January 2022 to August 2025 using the Error Correction Model (ECM) method. Independent variables used include the Consumer Price Index (CPI), the rupiah exchange rate against the US dollar (IDR/$), and the policy rate (BI Rate). Data was obtained from the publication of Indonesian Economic and Financial Statistics (SEKI) of Bank Indonesia. The results of the Dickey-Fuller Augmented Stationarity test showed that all variables were stationary at the first difference, while the Engle-Granger co-integration test confirmed the existence of a long-term relationship between the variables. The results of the estimation indicate that, in the long term, no variables have a significant impact on foreign exchange reserves. However, in the short term, the exchange rate has a positive and significant influence, while the policy rate has a negative and significant effect on Indonesia's foreign exchange reserves. A value speed of adjustment indicates that short-term imbalances are corrected towards long-term equilibrium each month, indicating a swift adjustment mechanism.
