The volume of Indonesian gold exports to Singapore increased eightfold compared to 2013. At the same period, Singapore, which is not a gold producer is one of the top 10 countries with the highest gold export value in the world, while Indonesia's position is left behind Singapore. This study aims to analyze the variables that affect the volume of Indonesian gold exports to Singapore in 2006-2017. The analytical method used in this research is Autoregressive Distributed Lags (ARDL). The results showed that in the short term, there were significant effects of gold export volume a quarter prior, Indonesian gold production a year prior, Singapore’s investments a year prior, and exchange rate. In the long term, the exchange rate and gold production were significantly affected by the gold export volume. The policy recommendation is government support in stimulating the establishment of national gold refining and manufacturing industry to increase profits by exporting value-added products through infrastructure and high technology support. The government should encourage the refining and gold manufacturing industries by implementing the Good and Service Tax elimination.","PeriodicalId":229902,"journal":{"name":"Proceedings of the International Conference on Trade 2019 (ICOT 2019)","volume":"194 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115487531","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This article tries to address some NTMs issues on Indonesian agricultural export products particularly the prevalence of NTMs using frequency ratio (FR), coverage ratio (CR) and regulatory distances (RD) analysis. This study utilizes data from World Intergrated Trade Solution (WITS). The study shows that Indonesia’s ability to get better market access to its major trading partners depend on its ability to comply with SPS and TBT measures, and this is reflected in their high prevalent index. However, the average coverage ratio on Indonesian agricultural exports is only 13%, implying that NTMs policy on agriculture products imposed by Indonesian FTA/CEPA trading partners impacted only 13% of Indonesian agriculture export products. The RD of agricultural products between Indonesia and some of its main FTA/CEPA partners is 0.011with Pakistan and Singapore, and 0.09 with the Philippines and Australia. The finding reveals that there is a “core” of countries with similar NTM patterns at the product level on animal and food regulations.,. Indonesia is encouraged to address NTMs issues with its FTA/CEPA trading partners, in particular on any stringent NTMs and procedural obstacles related to SPS and TBT implementation as they often burden exporters.

Cooperation within the RCEP can facilitate Indonesian trade as an effort to increase value added within global value chain framework. Economic cooperation is proven as a way to boost GVC participation within its member in the region, including the Regional Comprehensive Economic Partnership (RCEP) due to regulation uniformity. The study used Descriptive Qualitative statisctics and Trade in Value Added (TiVA) data aims to identify Indonesias GVC participation within RCEP as well as its position in GVC participation. Specifically, this study uses the participation index, the index of the number of production stages and index of the distance of the final product. The study shows that Indonesias GVC participation is higher than neighboring countries such as Malaysia and Thailand however, compared to other East Asian countries Indonesia is still low. Most of Indonesias GVC participation is as a supplier of raw material. Within RCEP, Indonesias participation in GVC is still dominated by Low Technology Industries.

However, as a net importer of agricultural products and the member of G33 countries, Indonesia should address the ER policy because it may have potential to increase prices and threaten food security in domestic market and G33 member countries. This study uses a descriptive qualitative statistical analysis to determine Import Dependency Ratio (IDR) and SelfSufficiency Ratio (SSR) for five main imported agricultural products by G33 countries such as rice, corn, soybean, wheat, and horticulture. The Computable General Equilibrium (CGE) Analysis using GTAP ver.9 is also used to analyze the potential impact of agricultural product export restrictions for five analyzed products on macroeconomic and sectoral indicators. Based on IDR and SSR it can be concluded that almost all G33 countries heavily rely on wheat imports, as many as 36 countries depend on imported wheat with IDR values varying between 70% 215%. On the other hand, several G-33 countries have a fairly good level of fulfillment of consumption from domestic production (SSR) or more than 80%. Moreover, based on the GTAP calculation on the Indonesia case, export restrictions will have a negative macroeconomic impact on Indonesia. However, in sectoral perspective Indonesian farmers/producers can take advantage of the impact of the export restriction policy as an opportunity to increase their production.

The purpose of this paper is to provide business strategies that support the competitiveness of the family business in the global value chain. We reviewed related literature on family business and agriculture to describe the challenge and propose strategies that can bridge agricultural family business to become competitive. The study highlighted two challenges, namely labor usage, and capital usage. The amount of labor usage in Indonesia's family business was higher than the global business. However, the competitiveness by labor usage was determined by knowledge transfer and farmers' cooperation. Thus, the total value of capital usage in Indonesia's family business was lower than the global business. The capital usage was driven the competitiveness by social capital reinforcement, capital allocation, and capital availability. In this case, The Indonesian family business was found not able to take advantage of capital usage. The study proposed a strategy for the family business was to overcome the threat of labor usage by using its capital usage strength. These findings highlighted the importance of strengthening family business in agriculture sector based on each strength to overcome global trade challenge and take the opportunity from it. This paper may avail governments in drawing up policies for assisting the family business in the agriculture area to get global. It also contributes to the limited source of references literature regarding family business in agriculture in Indonesia.

Therefore, it is crucial to create a competitive advantage in order to stay in the market. In the case of the tourism industry, creating competitive advantage could be done by providing an extraordinary experience which is the ultimate goal for travel leading to customer satisfaction and customer loyalty. This paper aims at exploring and developing a model of tourism value chain activities experience by tourist for competitive advantage creation. Tourism value chain activities model consists of three stages whereby each stage has its own type of measurement. The first stage covers the pre-trip experience, in this stage, the detailed information prior to departure will be discussed. Next stage is the trip experience, which are the tourism activities involved during the visit and experienced during the trip. Lastly the post-trip experience, whereby on this stage the output of the tourism value chain activities will be measured. The proposed measurement for this stage will be an evaluation of tourist satisfaction and tourist loyalty in order to create a competitive advantage. Future studies are expected in implementing these tourism value chain activities in specific tourism destinations (country) to measure the tourism experience.
