The Jakarta regulation for waste cooking oil (WCO) shows the desired WCO to Biodiesel supply chain through the DKI Jakarta Governor Regulation Number 167 the Year 2016. Still, the implementation of said regulation proved inefficient. The study aims to analyze the risks in the supply chain because the WCO to Biodiesel supply chain is vulnerable to different risks than the typical supply chain and the green supply chain. The method used in this research is the group analytical hierarchy process (G-AHP) approach to create a consensus model between actors of the supply chain. Deep interviews were conducted with six experts to identify the risks and the normal scale was used to quantify their preference. Then, the PriEst software assisted the risk weight calculation, AHP matrix validation, and consensus modelling. The findings show the supply chain is vulnerable to 23 risks, categorized into six risk categories. The three risks that cause the most uncertainties in the supply chain are supply chain design risk, key supplier risk, and financial source risk. Technology risks and asset failure risks are the least concern because most WCO conversion is not done in Indonesia. These findings would be useful for the government to focus its effort on the most critical risks.

Rice is the main consumption food for Indonesians. The demand for food increased from 114.6 kg per capita in 2016 to 124.89 kg in 2017. However, rice farmers and supply chain actors in rice agribusiness have experienced high challenges, such as production, transportation, price, product quality, and the environment. This research aimed to understand actors involved in the supply chain, their perception of occurring risks, and evaluation and risk mitigation in the supply chain. This was a quantitative descriptive study done purposively in Watugede Village, Singosari Sub-District, Malang Regency. Non-probability sampling was taken to gather primary data. The respondent of this research was 16 involved actors, from on-farm actors to consumers. The data were analyzed using the Fuzzy analytical hierarchy process (FAHP) to provide descriptive risk mitigation strategies. The results show that six involved actors are suppliers, farmers, grinders, traders, and buyers. Each actor faces different risks, and thus, the recommended mitigation strategies are adjusted to their risks. Sharing information, optimizing the level of supply availability, measuring supply chain performance, and building more coordination with the government are the best strategies to mitigate risks.

With the continuous development of China's agricultural economy, the concept of green production has begun to penetrate into the hearts of the people. Exploring a new circulation mode adapted to China's green supply chain of agricultural products is an important way to promote green production in China, and also an important condition to promote the successful transformation and development of China's rural economy. But in the process of building a green supply chain of agricultural products and exploring circulation mode, there are many problems that hinder the development of green industry economy. Therefore, it is necessary for the government to play a guiding role and actively guide farmers to explore green development ways and new circulation mode to meet their own development needs, which provides reference for better optimizing the new circulation mode of agricultural products supply chain in China.

Due to rapid economic development and population growth, environmental pollution problems such as urban pollution and depletion of natural resources have become increasingly prominent. Municipal solid waste is part of these problems. However, waste is actually an improperly placed resource. As a part of green supply chain management, remanufacturing can turn waste products into remanufactured products for resale. Based on the development status of China’s remanufacturing industry, this paper establishes three Stackelberg game models, namely the free recycling model (model N), the government regulation model based on the reward–penalty mechanism (model G), and the government dual-intervention model (model GF). In this study, the standard solution method for the Stackelberg game method, namely the backward induction method, is applied to solve the dynamic game equilibrium. For comparison, a further numerical analysis is also carried. The research results show that: (1) in the closed-loop supply chain based on remanufacturing, the strengthening of cooperation between manufacturers and remanufacturers is beneficial in terms of maximizing supply chain profits; (2) in order to maximize social benefits, the government needs to intervene in green supply chain management; (3) government regulation is particularly important when the remanufacturing industry is in the initial stage of development; (4) government intervention needs to be based on the development level of the remanufacturing industry; (5) in order to maximize social benefits, it is recommended that the government consider the ratio between the green consumption subsidies and the taxes on new products.

Purpose Without proper treatment, waste cooking oil (WCO) will bring serious environmental and health hazards, which can be effectively alleviated by converting it into biofuel. Subsidies from the government usually play a significant role in encouraging recycling activities and supporting sustainable supply chain. This paper aims to quantitatively investigate the incentive effects of government subsidies under asymmetric information. Design/methodology/approach This paper applies the principal–agent contract to compare the incentive effects of the two widely used subsidy modes (raw material price subsidy [MS] and finished product sale subsidy [FS]) in a management system which consists of the government and a bio-firm where the bio-firm’s conversion rate of the WCO remains as private information. Findings Results indicate that the two subsidy modes have the same performance under symmetric information, while under asymmetric information, the government always prefers the MS mode which is more environment-friendly. Besides, if the average conversion rate is large or the uncertainty level of the asymmetric information is moderate, the MS mode is Pareto-improving compared with the FS mode for the government and the high-type bio-firm. Only when the average conversion rate is small or the uncertainty level is very small/very large, the high-type bio-firm welcomes the FS mode. Originality/value Different from the existing literature, this paper applies the principal–agent contract into the WCO management system and quantitatively compares the two subsidy modes taking the practical problem of asymmetric information into consideration.

Abstract Based on the “three bottom line” and stakeholder theory, the paper considers the relationship and cooperation strategy between the government and the supplier and manufacturer of the green supply chain. By constructing the dynamic differential game model, the paper discusses the differences in the optimal effort level, green degree of product, reputation and the optimal benefit under the three situations of noncooperation, government promotion and collaborative cooperation. The results show that the optimal effort level, green degree of product, reputation and the optimal benefit in collaborative cooperation are obviously higher than the situations of non-cooperation and government promotion, and the cooperation of the three parties can promote the development of green supply chain. Government promotion is better than noncooperation. The government plays an active role in improving the optimal benefit and reputation of green supply chain. Finally, the reliability of the proposed proposition is verified by an example analysis, which provides an important reference for improving the efficiency of green supply chain.

The supply of environment-friendly products is an integral part of the green supply chain. Due to such reasons as lack of high-tech and lack of price competitiveness in contrast to traditional products, the manufacturers will not have incentive to produce and supply green products, so the Government should grant financial subsidies to producers which will compensate the profits entitled to them. Through the analysis based on game theory, the article concludes that there is disadvantage in constant subsidy and the variable subsidies will have more positive effects on the supply of environment-friendly products since the subsidy amount varies with the production scale.

Hierarchy Process

Increase in demand for clean energy is one of the strategic issues in Indonesia nowadays, considering the significant economic growth of the country. A conventional LNG supply chain is not the best solution taking into consideration its high investment. The possibility of using a small scale LNG supply chain concept (Mini LNG) is recently sought by the government and private sectors in Indonesia. It is even more promising when we consider the amounts and number of stranded gas fields in the country. One of the main obstacles to the development plan is the geographical position of Indonesia as an archipelagic country. This paper presents a case study of LNG supply chain model of 10 mmscfd Gas Sales Agreement (GSA) in Batam and its design of LNG transportation model from Batam to Siantan-West Kalimantan [1]. The distance between Batam and Siantan is approximately 392 nautical miles. Two main objectives are covered in this paper. The first one is an implementation of the Analytical Hierarchy Process (AHP) to select the best location for mini LNG plant, and the second one is to design the LNG supply chain model based on optimization approach. The AHP model uses a pairwise comparison of 4 (four) qualitative attributes and 14 (fourteen) sub-attributes. 3 alternatives of location for mini LNG plant are evaluated, namely: Tanjung Uncang, Pemping Island and Janda Berhias Island. A sensitivity analysis by varying the weight of some critical attributes is also conducted to ensure that preferred location is sensitively selected with minimum error. The optimization of the LNG supply chain model is carried out by means of Gradually Reduced Gradient (GRG) methods. The Objective is to attain one design that will minimize investment (cost). Decision variables of the model are LNG plant capacity, storage tank capacity in loading and receiving terminal, vessel size, number of round trip, number of operating vessels, regasification capacity at the receiving terminal, and others.
