Abstract

This research was conducted to determine the possible impact of an earthquake on the mainland of Wangi-Wangi Island based on the presence of shear strain on the surface ground (γ). The size of γ is obtained by multiplying the ground susceptibility index and the acceleration of basement ground or PGA using Nakamura’s technique. The data used are microtremor data and earthquake data from 1920 to 2020 sourced from the USGS. Microtremor data are obtained from the results of filtering ground vibration signals using a Band Pass Filter in the frequency range between 0.5 to 25 Hz. Ground vibration signals were recorded at 47 measurement points spread over the surface of Wangi-Wangi Island within 29.25 to 48.16 minutes. Furthermore, the microtremor data were processed using the HVSR (Horizontal to Vertical Spectral Ratio) method. The use of earthquake data must meet the requirements for a surface magnitude (MS) ≥ 5.0 SR and an earthquake epicenter depth (h) ≤ 45 km. The results obtained are the γ sizes of Wangi-Wangi Island in the order of 10-06 to 10-03. Based on the size distribution, it is known that the majority of the Wangi-Wangi Island area has the potential to experience cracks and land subsidence due to settlements if an earthquake occurs, and only a portion of the area is vibrating. In addition, it is also known that the mainland of Wangi-Wangi Island is not prone to landslides and liquefaction because γ<10-2.

Abstract

In today's dynamic global economy, organizations face increasing challenges in managing risk amidst market uncertainty. This paper addresses a gap in current research by focusing on innovative risk management strategies designed to effectively address these uncertainties. Using a qualitative research approach, this study investigates how organizations identify, assess, and mitigate risk through in-depth interviews and thematic analysis. The novelty lies in exploring the integration of traditional risk management frameworks with emerging qualitative methodologies to improve decision making and resilience. By leveraging qualitative insights, this research aims to uncover various risk factors that are often overlooked by quantitative approaches, thereby offering a comprehensive understanding of risk dynamics in complex global markets. This study contributes to advancing theoretical frameworks and practical applications in risk management, empowering organizations to proactively adapt and thrive in turbulent environments. Based on the evaluation that has been carried out, it can be stated that risk management plays a crucial role in influencing company performance. Risk management not only functions to manage company resources with efficiency, but also to optimize the results obtained so that the company can achieve the financial goals that have been set.

Abstract

Harga jual biji kakao di tingkat petani sering kali tidak mencerminkan kualitas sebenarnya, akibat keterbatasan akses informasi dan dominasi tengkulak dalam rantai distribusi. Penelitian ini menawarkan solusi dengan mengembangkan sistem digital berbasis Artificial Intelligence (AI) dan algoritma fuzzy logic, yang terintegrasi ke dalam platform e-commerce. Sistem ini dirancang untuk membantu petani menentukan harga jual yang adil berdasarkan kualitas biji kakao seperti kadar air, kebersihan dan tingkat fermentasi. Hasil harga prediktif yang muncul dapat digunakan sebagai acuan saat petani berinteraksi langsung dengan pembeli, tanpa perantara. Platform juga menyediakan fitur eduakasi dan informasi digital untuk meningkatkan literasi petani. Pendekatan ini memperkuat posisi tawar petani, menciptakan transparansi harga, dan membuka akses pasar yang lebih luas. Inovasi ini diharapkan membentuk ekosistem agribisnis digital yang tidak hanya cerdas secara terknologi, tapi juga adil dan berpihak pada kesejahteraan petani.

Abstract

Today's passenger terminal is starting to erode its existence with various problems plaguing it. This research was conducted to examine the existence of the Waramosio Terminal in improving the welfare of the local community in terms of a sociological approach and to analyze the efforts that must be made to optimize the terminal's function by the Southeast Sulawesi Provincial Transportation Service. The method used is a descriptive qualitative method by conducting interviews with ten informants. The theory used is Coleman's Rational Choice theory. The results found are that the existence of the Waramosio Terminal today is increasingly eroded and its function is decreasing. This needs to be paid attention to and efforts made by the Southeast Sulawesi Provincial Transportation Service to optimize the terminal's function and its existence in the community.
