In fact, many commercialized products were unable to survive in market. In order to avoid these failures, performance of technology has to be assessed. Technology readiness assessment for innovation of aromatherapy products or services represent assuredness to the products. Technological readiness levels (TRLs) are widely adopted to assess the maturity of new technology. The business process model of innovation performance toward commercialization is conducted using System Development Life Cycle (SDLC) method. Through SDLC, the innovation performance system entity and Business Process Modelling Notation (BPMN) were constructed. BPMN which constructs notation of business process shows that the stakeholders involved in innovation performance assessment are innovator, evaluator, research center and investor. TRLs system of aromatherapy products were then developed for innovation performance assessment. It was able to define criteria, attributes, and metrics for performance assessment based on the basic concept of TRLs and aromatherapy. Finally, validation was done using Fuzzy Inference System (FIS). The result shows that the developed TRLs system of aromatherapy products is valid for performance assessment. It is also conforming to TRLs and aromatherapy basic concept.

The primary processing of coffee produces waste from pulping and hulling activities. Waste can be processed further through composting, anaerobic water waste treatment and burning to be converted into electrical energy. Therefore, the calculation is needed that estimates the amount of potential biomass that is converted. Then, the purpose of the paper is to analyze each stage in the life cycle of Gayo Arabica coffee and calculate the potential amount of electrical energy produced. The life cycle assessment method uses material and energy analysis intending to explain the flow of inputs and outputs within the system boundary and analyze the movement and transformation of materials, energy, waste, and emissions. In the context of the paper, the study uses material flow analysis to estimate the biomass potential from solid and water waste treatment. The study uses interviews, observations and a cooperative report located in Central Aceh district as an Arabica coffee producer area in Indonesia. Production of Arabica coffee is managed by cooperatives involving small farmers and collectors from cultivation, primary processing, packaging, and delivery. Cultivation uses the agroforestry system with a shade tree of the type of lamtoro (Leucaena leucocephala). Packing with a pack of burlap is done by the cooperative. Activities undertaken cooperatives include the acceptance of coffee beans from the collector. Since 2016 cooperatives implemented a policy of processing coffee beans at the collector level. The estimation of the study shows that waste treatment through anaerobic water waste treatment, composting and combustion from 1 ton of cherry coffee (primary processing) has an energy potential of 34 kwh.

These by-products contain organic materials that cause environmental pollution and degradation. Some of the by-products are energy containingcompounds that can be used to supply energy needs in the production process. This study aims to develop a closed model of energy-independent Arabica coffee production. The model was developed based on mass flows in the coffee production process.One mass balance equation can be made for each stage of the process. The model showed that the optimal yield of green coffeebean production was 28%. Coffee production of a capacity of 5,500 kg of cherries per day has energy potential of by-products of 6,161,286 kcal originating from the outer skin, pulp and parchment. Energy conversion using boiler can meet production energy needs of 117.20 kWh per day. This study concluded that Arabica coffee wet processing can be developed as an energy independent production by optimally utilising of by-products.

These wastes pollute the environment because of their rich organic compounds that will undergo decomposition. The main compounds contained in the waste are energy-carrying materials such as fibre, carbohydrates, protein, and oil/fat. The use of these materials as energy sources can save natural resources while cutting the load of environmental pollution. This paper discusses the assessment of adequacy of energy contained in the waste and proposes an integrated flow model to support the agroindustrial production process. The amount of waste obtained from the mass balance model is then multiplied by the energy content of each waste to obtain energy potential. Energy conversion is used to calculate steam (heat) and electricity needed to support the production process. Some examples are given to show that agroindustry has the potential to become an energy independent industry by applying the principle of less input and multiple outputs through the reuse, recovery, and recycling of the waste. Some future research recommendations are proposed to enable the implementation of energy self-sufficient agroindustry.

Most energy used is fossil energy in the form of electricity and diesel oil which availability has declined so that affect the tapioca production process in the very near future. In addition to producing main products, tapioca industry also generates certain amount of by-products such as cassava's peel, stockpile and wastewater that potentially be utilized as an energy source. This research aimed to develop a model of a closed system of energy independent production process of tapioca through reusing the by-product as the energy source. Development of a closed system model was based on the mass balance, assessing energy content of by-products, and build a closed system of tapioca production process. This study used secondary data of processing stages and primary data of material balance from a tapioca industry. The results showed that the achievable yield of tapioca was 32%. The tapioca industry with 1,000 ton of cassava per day has the potential energy of 1,407,714,408 kcal per day derived from cassava stockpiles and cassava peels. This potential energy is able to meet the energy requirements of 99,261 kWh per day for the production process. Therefore, the tapioca industry is potentially being an energy independent industry by optimizing the utilization of by-products.

However, there is no strong cassava based processing industry (tapioca, cassava flour, glucose syrup, and ethanol) grow with good business insight. This review sees the gap comprehensively between the capacity to produce and availability of raw material (fresh cassava), and high potency of uses and increasingly down stream product demand. This paper ends with recommendations on how to bridge upstream potency and down stream demand through the development of cassava based industry. Special discussion on Cassava Research Center is provided.

An alternative model and an institutional model selected should consider the innovation taken, feasibility, the lowest cost, the lowest possible consequences or risks. This article was aimed to describe strategies for development of agro-industrial institutions and some other opportunities for novelty as a research contribution. Results of the analysis discovered some research opportunities that become challenges for researchers, in particular in the context of wide open agro-industries. They include ones related to the historical analysis, the comparative analysis and the functional analysis, the assessment of institutional positions, the structurization of institutional systems, future prospects, the assessment of potential innovations and the institutional performance measurement. In-depth review of one component or in depth-study of a combination of components is continuously required. Therefore, characteristics of each agricultural commodity, social dynamics, current development and technological advances, policy changes and global challenges become challenges crucial for development of agro-industrial institutions in the future.

Recycling the biomass as a source of energy and using the released water as a part of the production process will cut fossil fuel and water use. These approaches will significantly save resources and cut the environmental pollution load. The objectives of this study were to analyze the mass balance, assess the energy content of by-products, and build a closed flow of energy and water self-sufficiency in the white sugar production process. A mass balance model was developed to illustrate internal mass-flows and to determine the amount of by-products generated in the production process. The results showed that optimal use of by-products can produce energy and water exceeding the needs of the sugar processing itself, leading to the creation of energy and water self-sufficiency or an independent sugar production process. The potential energy contained in the by-products of a sugar mill with a capacity of 3000 tons of cane per day is approximately 2237 gigacalories per day, which could meet the energy needs of the mill with an excess of 37,081 kWh/day. The mill is also able to produce a net water surplus of 700 m3 per day. This research demonstrated that a complex mass balance model can be used to assess the level or possibility of sugar mill energy and water self-sufficiency. It is suggested that the sugar production process should be developed as a closed-production system that does not require the input of energy and water from outside the system. Application of this production system at a practical level will contribute to reducing sugar mill pollution, reduce coal and other fossil fuel use and help protect water resources from excessive exploitation. A closed production system can be applied to all industries that process raw material containing energy. In the short term, sugar production should be restricted in its use of fossil fuel, public electricity networks, and water from natural sources. In the long run, sugar mills should become multipurpose factories producing sugar, energy, and water.

The scenario developed to formulate production process based on gap analysis. The objective of the study was to compare the production and productivity of sugar mills through improvement efficiency. The method used in this research was quantitative descriptive method, making a description of the relationship between sugar yields determinant variables, including (1) determination of gap analysis on a benchmark, (2) prediction of sugar yields and bagasse using multiple linear regression, (3) energy calculations with NCV (Net Caloric Value) approach, and (4) partial productivity measurement. The results showed that scenario 3 increased the yield to 10.4% with an increase of white crystal sugar production by 24%, while scenario 2 increased the yield to 9.3% with an increase of white crystal sugar production by 11.7% compared to scenario 1. Increasing the efficiency of milling extraction (ME) capable of increasing the energy potential of 4.3 kWh. Improving the technical efficiency of the factory resulted in increased productivity of raw materials of 0.029 tons white crystal sugar/tons, productivity of machine work hours of 5.29 white crystal sugar per work hours, sugar productivity to the land of 1.79 tons white crystal sugar/ha and energy productivity 4.27 kWh/tons bagasse (R-value as a validation test prediction model is 97.1% and 72%).
