Abstract

Palm sugar has wide scope as an alternative sweetener in the Indonesian market. Palm sugar is a natural alternative to cane sugar which is less healthy and also more beneficial for farmers. The taste, sensory profile, and nutritional content of palm sugar vary based on the species, growing region, and climatic conditions. Currently, the traditional processing of palm sap in Kaliabu village results in lower yields and higher costs. There is enormous potential in the field of developing processing techniques (traditional processing, spray drying, membrane technology, and vacuum drying) to optimize palm sugar production in Kaliabu village. Spray drying is a non-conventional method that has the potential to be implemented in palm sugar production in Kaliabu village. This is because spray drying is quite good in terms of increasing antioxidant and phenolic content as well as storage capacity.

Abstract

In this article, we study several research about optimizing the adsorption of harmful compounds contained in batik dye liquid waste using activated carbon. The employment of naphthalene as a chromogenic agent in the batik industry introduces a significant quandary by contributing to water pollution through effluent discharge. Noteworthy efforts have been made by certain industries, employing activated carbon to mitigate the presence of Pb and Cr attributable to naphthalene. The principal objective of this exposition is to consolidate insights into the sequestration of perilous dyes within batik industry effluents, leveraging various forms of natural activated carbon. The kinetics of the adsorption process will be quantified utilizing the appropriate kinetic order formula, while equilibrium data will be scrutinized through reaction isotherms employing diverse models.

Abstract

Water is a basic need of living things that is very important to maintain its quality so that it does not cause problems. The method that can be used to improve water quality is to carry out the coagulation method using moringa seed coagulant (moringa oleifera) and alum which has been proven to be able to improve the quality of water. Both coagulants can reduce the following parameters, turbidity by reducing TSD, neutralizing pH, reducing dissolved metal levels, color, and reducing microorganisms contained in it such as E-coli bacteria and total coliform. The results of this study indicate that the two coagulants can reduce the parameter values of TDS, turbidity, iron content, E-coli, color, and pH in the sample water to be below the maximum limit or in accordance with drinking water quality standards, but the nitrate parameter is not yet below the maximum level. The optimum concentration to improve the quality of well water into drinking water is 2.5 ppm with an optimum residence time of 4 weeks.
