Abstract

Poverty is a problem that occurs throughout the world, especially in developing countries such as Indonesia. With a very dense population, especially in big cities, Indonesia faces various social problems. The poverty rate in Cilegon City in the last six years has fluctuated. However, the poverty line has consistently increased from IDR 428,867 in 2018 to IDR 663,533 in 2024. In 2023, the poverty rate in Cilegon City reached 3.98%, an increase of 0.34% compared to 3.64% in 2022. However, in 2024, the poverty rate decreased slightly to 3.75%.Consolidation of Targeting Data for the Acceleration of the Elimination of Extreme Poverty (P3KE) & Integrated Social Welfare Data (DTKS) by going through a data matching process using NIK (Population Identification Number) and Name data. The process is carried out by involving the SIKS -NG Operator (Next Generation Social Welfare Information System), which then after the matching results are known, they are then processed in Microsoft Excel Working paper to facilitate analysis and updating, so that the intersection between P3KE and DTKS data will be known. In the context of P3KE (Targeting the Acceleration of the Elimination of Extreme Poverty) data, ranking refers to the grouping of households based on welfare levels.

Abstract

Penjadwalan produksi yang optimal sangat penting bagi perusahaan manufaktur untuk menghindari penumpukan barang dan keterlambatan distribusi. Penelitian ini bertujuan mengoptimalkan penjadwalan produksi paving block pada Mulia Genteng Beton menggunakan metode Palmer. Data yang digunakan mencakup waktu proses tiap job, jumlah mesin, serta data permintaan bulan September 2022. Metode penelitian yang digunakan adalah metode kuantitatif dengan pendekatan eksperimen yang bertujuan untuk mengoptimalkan penjadwalan produksi pada sistem flowshop. Adapun tahapan dalam penelitian ini meliputi uji kelayakan data, perhitungan waktu baku, perhitungan dengan menggunakan metode Palmer serta perhitungan makespan. Hasil penelitian menunjukkan urutan job optimal adalah J2–J1–J3 dengan makespan sebesar 381.624,66 detik (±106 jam). Hasil ini sama dengan perusahaan namun dengan pendekatan yang lebih sistematis. Penelitian ini berkontribusi dalam memberikan rekomendasi metode penjadwalan sederhana namun efektif pada industri paving block.

Abstract

Rainfall prediction plays an important role in understanding the pattern of rainfall movement for daily life. This research aims to predict monthly rainfall in Medan Belawan using the Tsukamoto fuzzy logic method. Tsukamoto fuzzy logic is used to predict monthly rainfall in Medan Belawan. This method uses several steps, starting from data input, fuzzification, inference, to defuzzification to help predict rainfall. This research aims to apply Tsukamoto fuzzy logic to monthly rainfall prediction. Fuzzy logic has tolerance for imprecise data. This rainfall prediction uses 4 (four) input variables, namely air temperature, air humidity, air pressure and wind speed, and 1 (one) output variable, namely rainfall as a crips value which is the output generated for rainfall prediction. The data used is 12 monthly data from January 2023 to December 2023. The results show the accuracy of the fuzzy method of 57.75% using the MAPE calculation and show that the calculation of the Tsukamoto fuzzy method is sufficient or feasible to do.

Abstract

The rapid urban expansion of Medan City has intensified the complexity of municipal waste transportation, where limited fleet capacity, congested road segments, and long travel distances to the Terjun disposal site result in high operational costs and excessive carbon monoxide (CO) emissions. In addition, daily fluctuations in waste volume introduce uncertainty that disrupts routing efficiency and increases the risk of vehicle overload. This study proposes a Robust Optimization based Green Capacitated Vehicle Routing Problem model to minimize transportation cost and CO emissions while maintaining route feasibility under demand uncertainty. The model incorporates a Hamiltonian circuit structure to ensure closed-loop routing and applies the Nearest Neighbor Algorithm (NNA) as a constructive heuristic for generating initial solutions. Compared to commonly used methods such as the Clarke–Wright Savings algorithm, NNA provides faster computational performance, simpler implementation, and more stable feasible routes when integrated with robust capacity constraints. Using real CO emission data from major arterials in Medan, the model was evaluated across multiple uncertainty levels (Γ = 0–6). The results show that the robust model reduces overload risk by up to 12%, lowers total emission cost by approximately 5% relative to the deterministic solution, and produces more environmentally efficient routing decisions even when route distance increases slightly. From an analytical perspective, the RO Green-CVRP framework enables evaluation from operational, environmental, and robustness performance dimensions. This research contributes theoretically to green robust optimization and practically supports the development of adaptive, low-emission waste transportation strategies aligned with Medan’s sustainable urban development goals.

Abstract

Background: Perlang Village, located in Central Bangka Regency, is recognized as one of the earliest halal tourism villages in Indonesia; however, it has experienced a decline in brand strength due to limited digital literacy, simple promotional strategies, and the community’s insufficient understanding of comprehensive halal tourism concepts. This Community Service Program (PKM) aims to strengthen Perlang Village's branding as a halal tourism destination by enhancing community capacity in digital marketing, promotional content development, and the use of digital marketing tools. The method applied is the Asset-Based Community Development (ABCD) approach, which emphasizes the strengthening of local assets and active community involvement. Method: supported by in-depth interviews and Focus Group Discussions (FGDs) to map the village's potential and needs. The program was conducted through a series of training activities, including the introduction to halal tourism concepts, tourism package development, digital marketing practices, and a final evaluation. Results: Increase in participants’ understanding of digital marketing strategies, their ability to produce informative promotional content, and their skills in using digital tools to expand the reach of halal tourism. Although a slight decline was observed in certain post-test indicators, this reflects participants' improved reflective awareness of higher competency standards. Overall, the program generated a positive impact in revitalizing the image of Perlang Village as a competitive halal tourism destination. Conclusion: Moving forward, continued assistance and periodic monitoring are required to ensure that Perlang Village’s branding remains strong and sustainable in attracting tourists.
