Abstract The purpose of this research/study is to identify the actors involved in the value chain, analyze the added value received by each actor, and analyze the value chain of business actors who get the most benefits and related parties in the Toba Samosir Regency. The data analysis used in this research is in the form of qualitative and quantitative data analysis. Qualitative analysis is conducted to describe and analyze the actors involved in the value chain of the tilapia business. Quantitative research is carried out to calculate the costs and benefits used to determine the added value of the business. The results of this study are the flow pattern of the tilapia business value chain, starting from fish cultivators to consumers. The actors involved in the value chain consist of fish farmers, wholesalers, processors of tilapia, and distributors. The added value obtained by each tilapia value chain actor is 18.08% for tilapia cultivators, 5.31% for collectors, 60.76% for tilapia fillet processors, and 15.85% for tilapia fillet processors distributors. The business actor getting the biggest profit in the value chain is the fish processor, Rp. 102,048,667,500 per kg.

Abstract This study aims to modify the pyrolysis device that produces bio-oil with methyl esters, determine the content of methyl esters with GC/MS analysis, and test the performance of biodiesel using a diesel engine. This research modified the pyrolysis tube wall by changing the thickness of the stainless-steel material to 1.5 mm to facilitate the combustion process and heat transfer and reduce the equipment weight. Meanwhile, the tube base still uses 3 mm stainless steel to prevent leakage during the process because of high temperature (300 – 400°C). Using wood and coconut shell could accelerate the incomplete combustion process and produce higher methyl ester than using a gas stove. The process using wood and coconut shell could produce 35.88% of bio-oil produced while the process using a gas stove only produces 30%. The GC/ MS analysis has discovered that the content of methyl ester and ethanol was 60.12% and 1.13%, respectively. The obtained methyl ester was separated from the tar using a rotary evaporator based on the boiling point difference. Methyl ester from this husk can turn on the diesel engine with B20-B60.

Gambier is a significant Indonesian export commodity contributing more than US$ 55 million to the economy. Production of gambier is centered in the province of West Sumatra, specifically Lima Puluh Kota Regency. This research aims to analyze the structure, conduct, and market performance of gambier commodity in West Sumatra. Fifty-two gambier farmers and twelve gambier traders were interviewed with data that were analyzed descriptively to determine the market structure, market conduct, and market performance. Based on the number of end buyers (exporters) in West Sumatra, which are relatively small, only 16 companies compared to the number of sellers (farmers Gambier), this study concluded Gambier market structure tends to be monopsony. The majority of gambier exports from West Sumatra went to India. The market concentration analysis obtained a CR4 value of ≥ 0.8, which means low competition in the gambier commodity market. The market entry barriers analysis obtained an average value of MES of 35%, indicating the existence of barriers to market entry for new competitors. Four institutions were involved in marketing; collecting traders I, collecting traders II, interregional traders, and exporters. Of the four marketing channels, farmers-traders II-interregional traders (PAD)-exporters, was the most widely used, amounting to 51.92% of gambier trade. The research shows how different marketing channels benefit different institutions and provides suggestions to move towards a marketing system that provides more benefits to producers. The highest total marketing margin is on channel 1; Farmers-Merchants Merchants Gatherer I-II- Traders Inter (PAD) - Exporters. It occurs because channel 1 provides more marketing agencies. The highest of sharing farmers is the channel 4, i.e. farmers- interregional traders -exporters by 63.15%, and the lowest is in channel 2 (farmers-collecting traders II - interregional traders (PAD)-exporters) of 57.2 %.

The development of cassava agro-industry in Lima Puluh Kota District is very potential. It is related that Lima Puluh Kota District is the largest cassava commodity production district in West Sumatera Province. There are formal and informal institutions that support the development of agro-industry through various activities involving agro-industry. This study aims to describe the network structure of formal and informal institutions in the development of cassava agro-industry in Lima Puluh Kota District. This research uses mixed methods research. Data and information in this study are obtained from literature studies, observations, in-depth interviews, and Focus Group Discussions (FGD) used for quantitative and qualitative analysis. The quantitative analysis used descriptive statistics, and qualitative analysis used the interactive model. The results of this research showed that the frequency of interactions of informal institutions and agro-industry is more often than formal institutions. Social relations are more dominant than business relations in the network structure of formal institutions and agro-industry. On the other hand, the network structure of informal institutions and agro-industry, business relations are more dominant comparing social relations. Social relations can get through coaching activities such as counseling, training, procurement of production equipment, and business licensing. While business relationships can get through transactions such as purchasing, selling, land leasing, loan of capital, saving of money, and transfer of money. Informal institution relations occur in every agro-industry activity, starting from procurement of raw materials, auxiliary materials, processing, and marketing products. Formal institution relations occur in processing and marketing products.
