Abstract

Abstract-Program Postgraduate Program in Pancasakti University Tegal. 2019. Implementation of Procurement of Government Goods and Services by E- Purchasing Method in the Tegal Religious Court. The implementation of e- procurement in various agencies makes the process of interaction between users and service providers, and the community-run easier and accelerates the process of procurement of goods. Equally important, the implementation of e-procurement has automatically improved the control system for various rules and violations. Procurement of government goods/services electronically can be done by e- tendering and e-purchasing who use electronic catalogs and supply chain plays a vital role in the e-purchasing of the goods and services. The purpose of this study is 1) examine the implementation of e-purchasing in the application of rules regarding the procurement process of goods/services through the Tegal Religious Court, 2) explain the role of supervisory institutions in the implementation of the procurement process of goods in the Tegal Religious Court in anticipation of fraud that can cause losses to the state's finances. This type of research is normative-empirical legal research using a normative approach. The type of material used is primary, secondary and tertiary legal materials. Data collection methods used are library research and field studies.The results of this study include 1) procurement of goods/services with e- purchasing method is the right system in implementing procurement because it is more transparent, effective, efficient, compared to conventional systems, but the implementation is not optimal because a) is still coordinated so that time is not enough efficient, b) in e-catalog there is no information on the number of items available, so the buyer does not know the stock directly, c) the Supreme Court has not precisely targeted domestic production due to high specifications, 2) the role of supervisory institutions is not optimal because there are still many frauds and not yet the maximum application of a whistleblower because the procurement executors and the wider community are not familiar with the procurement of goods/services.

Abstract

This study analyzes the influence of Electronic Word of Mouth (eWOM) and destination image on visit intention and decision to Sebalang Beach, South Lampung. With tourists increasingly relying on online reviews, understanding these relationships is essential for effective destination marketing. The research addresses the issue of how eWOM and destination image affect tourists' decisions, aiming to provide insights for tourism stakeholders. A quantitative approach was used, employing a survey method with purposive sampling of 110 respondents who have visited or intended to visit Sebalang Beach. Data were analyzed using Structural Equation Modeling-Partial Least Squares (SEM-PLS) to test the proposed hypotheses. Findings indicate that destination image significantly influences visit intention and visit decisions, while visit intention also mediates the effect of destination image on visit decisions. However, eWOM does not have a significant impact on visit intention or visit decisions, and visit intention does not mediate the relationship between eWOM and visit decisions. These results suggest the importance of strengthening online promotional strategies and enhancing the positive image of Sebalang Beach. Encouraging content creation on social media and collaborating with influencers can effectively increase engagement and attract visitors. This study offers practical recommendations for tourism stakeholders to optimize Sebalang Beach’s potential and enhance its competitiveness as a tourist destination.
