Abstract

Indonesia as an agricultural country produces and consumes a huge amount of fruits. One of the popular fruits is durian (Durio zibethinus), which can create issues with the high amount of durian seeds. Durian seeds can be fermented quickly. Thus, if they are not processed immediately, it causes pollution to the environment, particularly an odor issue. One of the waste management is to convert durian seed waste into biochar, an ameliorant agent to improve soil quality. This study aims to analyze the physicochemical properties of durian seed-derived biochar under different pyrolysis temperatures. The results showed that the increases in the temperature allowed the creation of more porosity in the biochars, which is due to chemical structure and crystallinity arrangement. This is confirmed by the increases in surface area and total pore volume also decreases in particle size. The change in the chemical structure can be verified by the decreases in the biochar yield. The produced biochar from fruit seeds has excellent carbon content and elemental components such as potassium, magnesium, phosphor, and sulfur, informing prospective fruit seeds as a soil amendment fertilizer

Abstract

Household activities and beverage industries that use tamarind often generate waste in the form of tamarind seeds. Tamarind seeds account for approximately 40% of the total weight of the fruit. If these tamarind seeds are not properly managed, they end up as waste with no economic or other benefits. One effective waste management strategy is to convert tamarind seeds into biochar. This research aims to examine the characteristics of biochar produced from tamarind seeds at different pyrolysis temperatures. The results indicate that as the pyrolysis temperature increases, the fixed carbon content also increases. Pores begin to form on the surface of the biochar at a temperature of 400°C. We have identified functional groups such as C-H, O-H, C≡N, C≡C, C=C, C=O, CH3, C-O, and C-C in the biochar. The dominant elements in tamarind seed biochar are K2O, CaO, P2O5, SO3, and MgO, which are part of macronutrients and alkaline elements with the potential to improve soil quality as soil amendments.
