Abstract

Belitung Taro Starch (Xanthosoma sagitifolium), which until now has not been utilized properly used as raw material for making edible film with glycerol as plasticizer. Also added Kencur rhizome extract (Kaempferia galanga L.) to provide additional antimicrobial properties. In the resulting antimicrobial edible films were tested for antimicrobial activity using Staphylococcus aureus bacteria. Edible film with the addition of kencur extract has activity against Staphylococcus aureus bacteria characterized by inhibit zone with a diameter of 9 mm to 28 mm.

Abstract

Iodine value is the number of grams of Iodide absorbed by 100 grams of oil, is one of the quality standards of palm oil. Determination of Iodine value is done by titration of iodometri (Wi's method) with or without Sodium Acetate solution catalyst. The addition of a catalyst for the acceleration of the reaction so that the analysis time is more efficient. The test sample consisted of RBDPO, RBDPS, Cooking Oil IV 56, Cooking Oil IV 57, Cooking Oil IV 58, Cooking Oil IV 59, Cooking Oil IV 60. Results of Iodine Numeral analysis with and without catalyst for RBDPO samples were 52.24 and 52.35, RBDPS samples were 33.18 and 33.24, Cooking Oil IV 56 samples were 56.02 and 56.09, Cooking Oil IV 57 samples were 57.28 and 57.34, Cooking Oil IV 58 samples of 58.00 and 58.10, Cooking Oil sample 59 that is 59.17 and 59.21, sample of Cooking Oil IV 60 that is 60.42 and 60.46. The test results of each sample showed no significant differences with standard iodine numbers. T Test is performed for determination of data acquisition of Iodine number acceptable or not. T test result of Iodine number using catalyst and without catalyst of RBDPO sample obtained t0<ttable that is 1.947<2.015 and sample RBDPS 1.924<2.015 so that method obtained can be accepted (valid).

Abstract

The gambier industry in West Sumatra, particularly in Payakumbuh, is Indonesia's largest producer of gambier, contributing approximately 80-90% of the national production. This high production rate results in increased waste generated during the production process. This article discusses the potential environmental pollution from wastewater from the gambier industry and efforts to address this issue. The study notes that coagulation-flocculation and adsorption methods have efficiently treated textile industry wastewater. The study discusses the Wastewater Treatment Plant (WWTP) conditions in the gambier processing industry before optimization and the steps taken to improve its performance. Additionally, the study analyzes wastewater characteristics before and after treatment. The results of this study indicate that adding aerators and pH-adjusting agents to the WWTP can improve wastewater treatment performance, resulting in effluent that meets the quality standards set by government regulations. Moreover, treating wastewater with adding Poly Aluminium Chloride (PAC) reduces COD and BOD, indicating the degradation of organic components in gambier waste. COD removal efficiency is 92.65%, and BOD removal efficiency is 58.01%. This optimization results in an improved quality of gambier industry wastewater, reducing its negative environmental impact. These efforts are crucial to meet environmental regulatory standards established by the Indonesian government.
