Abstract

This research was conducted to examine the impact of empowering and fostering innovation of peasants as an activity that summarizes the values to build a new paradigm in agricultural development. The role of the agricultural sector is very strategic, not only in order to achieve food self-sufficiency but also in order to expand non-oil and gas foreign exchange sources. The purpose of this study is to see the impact of the strategy and pattern of relations between the Aceh Community Empowerment Institution (LPMA) in implementing the empowerment program and fostering farmer innovation in Nisam District, North Aceh Regency. The method used in this study is a qualitative method with data collection techniques through interviews, observation and documentation. The phenomenon of poverty for the people in Nisam District, North Aceh generally comes from the agricultural sector due to the lack of support for knowledge and business capital. This empowerment activity is carried out by the Aceh Community Empowerment Institute (LPMA), a non-governmental organization. Research shows that the optimization of empowerment and innovation carried out by LPMA has contributed to increasing community empowerment and also contributed to business partnerships for poor farmers to increase community empowerment.

Abstract

We provide an overview of the research on cultivating sustainable employee engagement and well-being initiatives in Indonesian organizations. The study aimed to comprehensively examine the strategies employed, the challenges faced, and the impact of these initiatives on organizational performance in the Indonesian context. The research was rooted in a mixed-methods approach, combining qualitative and quantitative methods to understand the subject matter better. Data was collected from surveys, interviews, and organizational records. Stratified random sampling was employed for surveys, while purposive sampling was used for interviews, ensuring a diverse and representative dataset. Our analysis incorporated descriptive statistics and inferential statistical methods, such as regression analysis, for quantitative data. Qualitative data underwent thematic analysis, allowing for the identification of patterns and themes. Integrating both data types enabled triangulation and a more profound insight into the research questions. Ethical considerations were paramount throughout the research, with data treated confidentially and participant identities protected. Informed consent was obtained from all participants, and potential biases or conflicts of interest were transparently addressed. While the mixed- methods approach enriched our understanding, it did pose resource and time constraints. While valuable within the Indonesian context, the findings may not be universally applicable. Additionally, challenges related to data collection, such as participant availability and the completeness of organizational records, were acknowledged. This research contributes to the existing body of knowledge by offering insights into the strategies and impact of sustainable employee engagement and well-being initiatives in Indonesian organizations while shedding light on the challenges faced in implementing such programs.

Abstract

Determining strategic warehouse locations is complex because it involves various criteria that are often conflicting, such as cost, ease of access, capacity, and operational risk. This study aims to evaluate a robust model in a Decision Support System (DSS) for warehouse selection using a Multi-Criteria Decision Making (MCDM) approach. The applied methodology combines several MCDM techniques, namely the Analytical Hierarchy Process (AHP) to determine the criteria weights and the Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) to rank alternatives. In addition, a sensitivity analysis is used to test the level of stability and resilience of the model to changes in criteria weights. The results show that the developed model is able to produce stable and responsive recommendations to variations in decision parameters. The sensitivity analysis also reveals that several criteria have a significant influence on the final result, thus requiring more attention in the weighting process.

Abstract

Sea transportation on route X plays a vital role in community mobility but still faces various safety risks that are not yet systematically managed. This study aims to identify risk events and risk agents, determine risk priorities, and propose mitigation strategies for passenger boats. A mixed-method approach was applied, with data collected through field observations and interviews with boat operators, then analyzed quantitatively using the House of Risk (HOR) phases 1 and 2 and the Bowtie diagram. The results identified 10 risk events and 18 risk agents, with the highest risk being boat overload and the lowest risk propeller entanglement in fishing nets. Pareto analysis revealed 9 dominant risk agents and 14 proposed mitigation actions. The Bowtie diagram illustrated the relationship between causes, events, and impacts with 6 main top events. Therefore, operators are recommended to implement and continuously evaluate mitigation strategies to minimize safety risks.
