: 2015 saw all UN members embrace the 2030 Agenda for Sustainable Development. It aims to create a global collaboration to achieve peace and prosperity for the planet and people. 17 SDGs aspire to improve the world by 2030 without excluding anybody. This study will evaluate how hotels fulfill SDGs sustainably, especially SDG6. The data from 57 star-category hotels were collected from Rajasthan, India, and analyzed. Results indicate that water conservation, sanitation, and hygiene for everyone contributed significantly to sustainable development. According to findings, different-star category hotels contribute differently to SDG6 by implementing sustainable practices to satisfy environmental SDGs.

: This paper presents a comprehensive investigation utilizing simulations to analyze the peak force and energy absorption characteristics of cylindrical configurations, as well as a novel spiral crash box design inspired by the albuca spiralis form. The study aims to evaluate the behavior of these designs in low-speed collisions by utilizing aluminum and steel as two different materials. Four primary forms of thin-walled structures, including concentric circles, tangent circles, half-balanced circles, and spiral circles, were thoroughly examined using finite element analysis. Mesh-independent tests were conducted to ensure the accuracy of the simulation results, and various crumple displacements were compared to determine the optimal mesh sizing. The numerical results demonstrate a significant reduction in peak force for the aluminum crash box, with a remarkable 60% decrease compared to the steel crash box. Furthermore, the spiral shape, identified as an optimized design, exhibits a low peak force of only 118.42 kN and offers superior energy absorption of 9.15 kJ per kilogram compared to the other designs. Consequently, employing nature-inspired designs provides substantial benefits for enhancing crashworthiness in energy-absorbing devices.

: This paper introduces the mission analysis of Small Scaled LNG Carrier (SSLNG) as LNG feeder transportation in Eastern Indonesia. This study aims to obtain an LNG delivery model from the Ambon Hub to all gas power plants in the Maluku and Papua regions. There are currently about 33 prioritized Mini Gas Power Plants (PLTMG) in eastern Indonesia as proof of the Indonesian government's commitment to lowering carbon emissions. With a market share of 14.09 % of the total domestic gas demand, the electricity industry is one of the primary consumers of domestic gas demand. Mission analysis was carried out on a type C tanker as a gas storage system because of its advantages. This analysis studies the primary transportation demand for LNG to create the best LNG supply chain scenario for eastern Indonesia. Supply and demand analysis is also carried out to obtain the optimum ship size. In addition, planning and optimization of shipping routes have also been carried out, considering the limited time for LNG storage. Several Vehicle Routing Problem (VRP) analysis methods found that the Heuristic method is more effective than other methods, with an efficient delivery time of 2-3 days, which is better effective with the choice of a predetermined operational.

: System performance analysis and comparison are necessities for ensuring the optimal operation of a photovoltaic (PV) power plant system. The primary metric that affects the PV system's productivity, dependability, profitability, ecological footprint, and grid compatibility are called Key Performance Indicators (KPIs). This study analyzes the KPIs of a 93.6 kW grid-connected rooftop PV system in South Tangerang and then compares them with the previous studies. Solar irradiation and output power data are collected. Then a modified extrapolation approach is used to fill in data gaps before proceeding with the performance parameter calculation. The performance indicator analysis refers to the IEC 61724-1 standard, including performance ratio (PR), final energy yield, system efficiency, system losses, and capacity factor. The results indicate that the PR, final energy yield, system efficiency, losses ratio, and average daily capacity factor varied from 82.0% to 91.6%, 2.94 to 3.70, 13.7% to 15.7%, 8.4% to 18.0%, and 12.12% to 15.67%, respectively. Compared to other studies, the PR values are much higher than expected. All of the other parameters, however, are normal. As a result, it shows that the PV system is working correctly.

: The price of international Liquified Petroleum Gas (LPG) has suffered in Indonesia, leading to its replacement with renewable ones, such as syngas. This study focuses on the techno-economic analysis of the 1-megawatt updraft fixed bed gasifier using a garden waste biomass. Three syngas price scenarios are considered, and the weighted performance index ranks the scenario and performs a sensitivity analysis on the best rank. The scenario of the 40% syngas price being less than the retail non-subsidized price fits and offers attractive economic feasibility to investors, balancing consumers' purchasing ability and government subsidies.

: The optimal power flow (OPF) issue is a critical optimization job in the operation and planning of power systems. It entails establishing the best settings of control variables to minimize generating costs while meeting operational restrictions. Traditional optimization techniques often struggle to handle the complexities and uncertainties inherent in power systems. This paper introduces fuzzy systems' concepts and their integration with genetic algorithms. It then delves into the many possibilities for power system optimization problems. The first section introduces the fundamental ideas of fuzzy, while the second section explores its structure and components. The third section explores the genetic algorithm's synergism with the fuzzy technique. The suggested technique was evaluated on an upgraded IEEE 30-bus system, with an optimal solution indicating fuel cost reduction under various linear and non-linear constraints. The suggested methodology's results were compared to all those mentioned in the literature. The outcomes of the offered methodologies are encouraging, demonstrating the efficacy and resilience of the proposed procedures. The synergism of the fuzzy system with the genetic algorithm offers several advantages, including flexibility in handling uncertainties, adaptability to complex systems, and the potential for discovering innovative solutions. However, it is important to carefully design the fuzzy system's rule base and appropriately set the genetic algorithm's parameters for optimal performance.
