Global partnerships based on sustainability standards compiled by international NGOs are needed to achieve social, economic and environmentally sustainable development, as well as to deal with global uncertainty in trade and business of agricultural commodities, including coffee in Indonesia. This paper aims to compare the implementation of global partnership standards in coffee between Indonesia and other producer countries. The Study focused on sustainable standard-compliant in coffee such as 4C and Organic certification standards. Trade and sustainability map tools were described. The findings demonstrate that there were only 8 percent and 9 percent of the Indonesian coffee area certified by 4C and Organic, respectively. Indonesia placed at number fourth of 4C implementation in the worldwide after Brazil, Colombia, and Viet Nam. Indonesia is also placed at number fourth of Organic implementation in the worldwide after Mexico, Ethiopia, and Peru. To compete in the potential market, Indonesia’s commitment to implement sustainable standard-compliant in coffee is needed. Therefore, Indonesia has to increase the coverage of sustainability standards certified area to meet the global market demand. The government also should implement the right policies and programs to enhance the sustainability compliance of national coffee stakeholders.Keywords: coffee, global trade partnership, sustainability standards, global value chain

Herding Behavior is an irrational investor behavior, because investors do not make investment decisions based on economic fundamentals of risky assets, but based on others investor in the same condition, or following market consensus. Herding behavior indications can be seen from relation between dispersion of stock return (Cross Sectional Absolute Deviation, CSAD) and market portfolio return. If herding behavior exist, CSAD increases lower than increase of market portfolio return moreover, CSAD will decrease even though market portfolio return increases. Herding behavior in stock market can trigger mislead in stock pricing because is bias among investors in analyzing risk and return. To understand relationship between CSAD and market portfolio return in some conditions, Quantil regression is used. Result gained from this research is that in Indonesian and global Asia Pacific stock market, herding behavior occurs in a market stress condition, whereas in normal condition or in condition of very high stock return, investor behavior tends to be more rational. Keywords : herd behavior, Quanrtile regression, CSAD

Unemployment is a problem that occurs in many countries and often gets special attention both from policymakers and academics. This fact is because if not addressed, it will cause socio-economic problems in the country. Therefore it is necessary to formulate the causes of unemployment by involving spatial aspects to avoid biased and inefficient estimates. This study aims to find the determinants of unemployment rates in Indonesia, including calculating the direct and indirect effect of using the spatial Durbin models (SDM) in the period 2000-2017. The results of this study indicate that the overall independent variables used significantly influence the unemployment rate in Indonesia. Besides, it turns out that the higher education variable completed by the population of a region has the most significant impact both in decreasing unemployment in a region and neighboring regions. Therefore, the policy taken should pay attention to this.

This study aims to develop a model of the future of Indonesia’s food consumption up to 2045, using a baseline of food consumption in 2017 and projections to 2025 as milestones, and to draw policy relevance on food and related issues for the next Medium-Term Development Planning of 2020–2024. The projected demand of Indonesian food consumption is built based on the functional relationship between income and food consumption at the baseline using three different scenarios of economic growth: baseline, moderate, and optimistic. Method of Almost Ideal Demand System (AIDS) was implemented to estimate changes of food consumption. Susenas data from 2017 is used as the baseline of food demand model. Susenas data from 1990–2016 is used to analyze selected food consumption trends and the relationship between food consumption, price trends, and income in all 33 provinces of Indonesia. The results show that future food demand in Indonesia is determined by existing demand, income, price and its composition, and various other factors that affect the behavior and trends of consumption. The policy should focus on the balance between demand-side management and supply-side or productivity improvement, as the majority of food production centers are located in Java.

This study analyzes the relationship between credit risk and profitability on the capital adequacy ratio (CAR) of commercial banks in Indonesia. The empirical model result shows that credit risk and profitability performance altogether significantly influence the capital adequacy ratio (CAR). Partially, the variables that significantly influence the CAR are the characteristics and complexity of the bank group. This study also suggests that the pace towards the long-term balance is, in general, less than one year. Capital ratio in the banking industry is 8%, indicating the bank has set aside to anticipate the impact of external factors as well as to comply with Bank Indonesia Regulation Number 15/12/PBI/2013.

Dioxin/furan is one of the persistent organic pollutants (POPs) that the government and public in Indonesia has not taken care of, as there is currently no policy on reducing dioxin/furan emission, even according to previous research dioxin/furan emission has already high. Steel industries produce dioxin/furan emission that will give negative impact to the people (cancer and death) and environment. The objective of this research was to estimate dioxin/furan emission and to determine factors that influence dioxin/furan emission concentration on the air, especially from steels industries. Methods employed in this research used emission factors to estimate dioxin/furan emission and Gaussian dispersion modeling to estimate emission concentration. The result showed that dioxin/furan emission is 9,38-13,54 gTEQ and it has to be reduced. Production is main factor to contribute dioxin/furan emission to the air. Besides that, emission concentration also depends on temperature, wind speed, height of stacks and radius from the site to the recipient. The conclusion of the research is dioxin/furan emission should be reduced, by means of first or second treatment.

The enhancement quality of clove leaf oil by purificationThe clove leaf oil is produced by distillation from the whole leaves and twigs of the clove tree. The color of the oil is brownish black and dirty. That condition is due to the presence metal ions of Mg, Fe, Mn, Pb and Zn in the oil. Those metal ions may come from the clove leaves and distillation apparatus. That problem could be solved by purification process. The purifications done in this research were adsorption using bentonite and chelating process using citric acid. The objective of this experiment is to find out the suitable concentration of bentonite and citric acid and their effects on the clearness, brightness, color and quality of oil. This experiment consisted of three activities, those were: (I) Analysis of clearness, brightness, color and quality of oil before adsorption or chelating process. (2). Purification of oil. Adsorption experiments were conducted using Completely Randomized Design, with ten treatments (1%,2%.3%,4%. 5%, 6%, 7%, 8%,9% and 10% of bentonite) and three replications. Chelating process experiments were done using a Completely Randomized Design, with five treatments (0.2%, 0.4%, 0.6%, 0.8% and 1.0% of citric acid) and three replications. (3) Analysis of clearness, brightness, color and quality of oil after adsorption or chelating process. Result showed that increasing of bentonite concentration from 1 to 10 % in adsorption process could enhance the clearness of oil from 31.2 %T to 91.7%T, enhance the brightness of oil from 32.93 to 48.42, enhance the yellowish color of oil from 11.41 to 42.65, and enhance the quality of oil.
