Abstract

Indonesia has abundant potential for solar energy. The decrease in the cost of solar power generation components can bolster the development of solar power plants. Due to its geographical characteristics, it is essential to analyze the feasibility of using solar power plants as a primary renewable energy source in Indonesia, especially in Sumatra Island. One of the critical aspects of developing solar power plants is determining the suitable location of the power plant and allocating the electricity generated to the regions. Therefore, this study considers the Capacitated Location Allocation Problem (CLAP) to determine the optimal placement of solar power plants on Sumatra Island to minimize investment and transmission costs. To address the problem, we explore three metaheuristics, namely Particle Swarm Optimization (PSO), Simulated Annealing (SA), and Large Neighborhood Search (LNS). The results obtained by these metaheuristic methods show significant differences in cost, with SA providing the best solution with the lowest cost. The investment and transmission cost can be minimized by solving the CLAP to obtain optimal solar power plant placement while enhancing the region's resilience in implementing distributed generation.

Abstract

Purpose: The purpose of this study is to evaluate the Green Supply Chain performance of hotels in Bali. Research methods: This study uses primary data obtained from questionnaires using a sample of three division heads per hotel and secondary data obtained from past hotel data. The data is processed using excel. Results and discussion: Two hotels obtained results of 66.48 and 75.02. These scores fall into the Average and Good grades. There needs to be some prioritized improvements with SNORM scores below 60 from two different hotels, namely water used, energy used, % suppliers with an EMS or ISO 1400 certification, supplier lead time, delivery item accuracy, and source flexibility. Implication: Recommendations that can be given are the use of PLTS, other water sources, and good communication with suppliers.
