Financing risk is a condition of uncertainty that affects the success of a business to gain profit. Meanwhile, profitability is the ability to generate profits based on the capital owned. This study aims to analyze the risk and profitability of financing in the tapioca agro- industry using an interest-free calculation basis. The data used are primary data from field observations at the center of tapioca agro-industry in Ciluar, Bogor Regency, and secondary data from literature studies. The analysis is carried out by calculating the risk of loss and profitability of financing using the assumption of an acceptance rate of 10% of the total capital and when the level of acceptance falls -10% of the total capital owned. Furthermore, a comparison is made between tapioca agro-industries that use an interest-bearing financing scheme and an interest-free financing scheme which includes variables of risk of loss, income level, and profitability level. The research results prove that the bigger the loan used, the greater the risk to be borne. Another finding, interest-free financing in the tapioca agro- industry has a higher rate of return and income than interest-bearing financing

Since Indonesia have signed and ratified Stockholm Convention on Persistent Organic Pollutants (POPs) in 2009, the country must make efforts to manage POPs appropriately. A number of pollution evident of POPs has occurred in Indonesia, either air, soil or water. Agricultural soils are not excluded from POPs pollution as the result of halogenated pesticide uses or other unidentified sources. Contamination of POPs to humans have been detected, as well as indicated potential exposure of POPs to humans. Based-catalyzed decomposition is a method that can be used to decompose or decontaminate POPs. Limestone can be processed to produce calcium-based catalyst that can apply for POPs decomposition. Indonesia is a country rich in limestone natural resources to produce calcium. However, calcium is inferior to sodium or potassium in reactivity for the dehalogenation of POPs. Thus, more evaluation is needed in order for synthesizing proper and economical calcium-based catalyst to alleviate POPs pollution in Indonesia.
