Abstract

Finished leather, a primary material for making shoes, bags, and wallets, is processed through tanning to remove veins and feathers. Liquid waste contains a high demand for chemical oxygen (COD), chloride, chromium, and sulfide that can affect river water quality if not treated further. This research was conducted at PT X in Malang City, where liquid waste treatment using an aerator is considered less effective. The tool used in this study is a jet aerator to increase the spread of oxygen in the aeration process. The study aimed to assess changes in the characteristics of tanning liquid waste (pH, temperature, total suspended solids/TSS), and COD) and the effectiveness of using jet aerators in aeration methods in tanning liquid waste treatment. Aeration is carried out for three days. The treatment carried out is aerator + 15 L (A15), jet aerator + 15 L (JA15), and jet aerator + 20 L (JA20). The data were analyzed using Factorial Complete Randomized Design followed by the Smallest Significant Difference test. pH and temperature have met quality standards, while TSS and COD have not. The results showed that the jet aerator +15 L (JA15) decreased maximum tanning liquid waste characteristics on day 1. In contrast, aerator +15 L (A15) and jet aerator +20 L (JA20) decreased maximum waste characteristics on day 2. The jet aerator+15 L (JA15) treatment provides the highest effectiveness value compared to other treatments. COD decreased 49.2%, and TSS decreased 49.7%.

Abstract

Powdered honey represents a development from liquid honey to a powdered form. Product development is a critical component for businesses to be sustainable. Powdered honey processing is significant because it extends shelf life, facilitates transportation and storage, and makes it easier to utilize in a variety of food and beverage items. Furthermore, powdered honey can broaden market reach, provide value, and meet consumer desire for more practical and long-lasting products. Producers can use economic analysis to examine several components of their final product. By taking essential elements into account, business leaders can make better judgments about investments, machinery selection, and cost control to optimize earnings. The purpose of this study was to evaluate the economics of using vacuum drying equipment with a jet air system to produce powdered honey. The investigation was carried out at the Lastrindo Engineering Laboratory in Klojen, Malang, Indonesia. The results show that producing powdered honey with a vacuum drying machine and a jet air system has a positive NPV of IDR 640,134,063; a B/C Ratio of 1.22; and an IRR of 73.93%, making the investment plan for this machine economically viable. According to sensitivity analysis, increases in raw material prices and labor wages have a smaller impact than a loss in production, which has the greatest influence on the vacuum drying machine's profitability in powdered honey manufacturing.
