Abstract— The supply chain in the 4.0 era wanted consumers to be closer to producers. Problems that occur in the supply chain are supply chain information flow is still long, there is no transparency, marketing coverage is less extensive, and documentation of activities is not good. The purpose of this study is to analyze the condition of the Kelompok Tani X cocoa supply chain and to identify the attributes of the blockchain based group cocoa supply chain farmers. The method used is the System Development Life Cycle (SDLC) and Unified Modelling Languange. The results obtained are that the supply chain information flow in the X farmer group is still overlapping, and has not been systematic. Actors consist of farmers, farmer leaders, processing factories (Kelompok Tani X), and retailers. Activities that occur are signing up, logging in, filling content, transactions, shipping, validation, and returning goods. The conclusion is the supply chain activities of the Kelompok Tani X have not been documented. The blockchain system that is designed is adjusted to the situation, so it is expected to be able to make the administration and documentation system better.  Keywords—: Agroindustry 4.0; supply chain; system development life cycle; transparency; unified modelling languange.

The Impact

The adoption of renewable energy technologies in developing nations is recognized to have positive environmental impacts; however, what are their effects on the electricity supply chain workers? This article provides a quantitative analysis on this question through a relatively new framework called social life cycle assessment, taking Malaysia as a case example. Impact assessments by the authors show that electricity from renewables has greater adverse impacts on supply chain workers than the conventional electricity mix: Electricity production with biomass requires 127% longer labor hours per unit-electricity under the risk of human rights violations, while the solar photovoltaic requires 95% longer labor hours per unit-electricity. However, our assessment also indicates that renewables have less impacts per dollar-spent. In fact, the impact of solar photovoltaic would be 60% less than the conventional mix when it attains grid parity. The answer of “are renewables as friendly to humans as to the environment?” is “not-yet, but eventually.”

Revenue Model

By establishing a two-level symbiotic supply chain system consisting of one supplier and one manufacturer, we use Stackelberg method to analyze the optimal price and revenue model of supplier and manufacturer in the symbiotic supply chain under two power structures in which the supplier and manufacturer are dominant respectively, and analyze the influence of the degree of symbiosis and power structure on the model. Through comparative analysis, we find that: There is a relationship between the income level and the degree of symbiosis in the symbiotic supply chain. The change of power structure will affect the relative benefits of suppliers and manufacturers in the symbiotic supply chain. The manufacturer’s expected unit product revenue will affect the supply chain revenue when the manufacturer is dominant. Finally, the sensitivity analysis of relevant parameters is carried out through an example analysis, and the validity of the conclusion is verified. This paper has a guiding significance for the behavior of enterprises in the cogeneration supply chain.
