Pengaruh Koagulan Biji Asam Jawa (Tamarindus indica) Terhadap Efisiensi Penurunan Zat Organik Pada Air Gambut

Abstract

Organic substances in peat water cause smell, have a brown color and taste, in addition to that it can interfere the processing process by forming carcinogenic trihalomethane which is produced from the reaction between organic compounds and chlorine. Peat water used in this study came from the village of Tuah Indrapura, Siak Regency with a concentration of organic matter of 95.2 mg/L. Based on Permenkes No. 492 of 2010 the concentration of organic substances exceeds the quality standard, so it needs to be treated before being used as a source of clean water. Therefore, in this study, uses the coagulation method of flocculation by utilizing natural coagulants, namely tamarind seeds (Tamarindus Indica). The study was conducted using variations in the size of biokoagulan by 200 mesh, 230 mesh, and 270 mesh with a dose variation of 1 gr, 2 gr, 3 gr, 4 gr dan 5 gr. The result showed that using 270 mesh biokoagulan particle size as much as 2 grams can set aside organic matter by 64%. This allowance is not large enough because tannins only form aggregates with organic substances in the form of proteins and alkaloids.

Utilization of Tamarind Seed Biocoagulant as Learning Material for Water Purification Practicum in Colloidal System

“…Based on interviews with two students about the ease of understanding and the ability to stimulate interest in learning, the results showed that students were interested in this practicum design because it was easy and could increase their understanding of the nature of colloidal coagulation. Using appropriate media for the material being taught effectively stimulates student interest, increases participation in the teaching and learning process, and enables students to easily grasp the material, thus increasing student achievement (Rasanzani et al, 2017).…”

Uji efektivitas antidiare ekstrak etanol biji asam Jawa (Tamarindus indica L.) terhadap mencit jantan dengan metode transit intestinal

“…Biji asam jawa mengandung tannin dan beragam senyawa polifenol seperti katekin, serta banyak jenis procyanidin. Khususnya, oligomer procyanidin tetramer sekitar 30,2%, procyanidin heksamer sebesar 23,8%, procyanidin trimer sekitar 18,1%, procyanidin pentamer sebesar 17,6%, procyanidin B2 sekitar 5,5%, epikatekin sebesar 4,8%, dan juga taxifolin, apigenin, eriodictyol, luteolin, dan naringenin (Riyandini & Iqbal, 2020). Tanin berfungsi sebagai adstringen yang memiliki kemampuan untuk menyusutkan selaput lendir usus, sehingga seringkali digunakan sebagai pengobatan antidiare (Rahmadani, 2021).…”
