Abstract

Tofu liquid waste is a white liquid with a thick texture derived from unused tofu production. Tofu liquid waste contains nitrogen, phosphorus, potassium, and protein, which are easily fermentable. It will pollute the environment and cause a bad smell if it is directly thrown away without prior processing. Therefore, tofu liquid waste was processed into organic liquid fertilizer. The purpose of this study was to determine the effect of fermentation time and sugar ratio on the levels of N, P, K The manufacture of liquid fertilizer involves a fermentation process by adding Yakult and EM-4 because both contain lactobacillus bacteria which can help the fermentation process. The sugar and coconut water were also added in a ratio of 1:0.075, 1:0.125, and 1:0.25. The process of liquid waste fermentation was carried out for 5 days, 10 days, 15 days, and 20 days. Fertilizers were tested using the Kjeldahl method for nitrogen (N) levels, spectrophotometry to determine phosphorus (P2O5) levels, and AAS (atomic absorption spectroscopy) for potassium (K2O) levels. The best levels of N, P, and K were produced from tofu waste with a fermentation process for 10 days by 0.662%, 1.133%, and 1.239%, respectively.

Abstract

A heat exchanger or commonly referred to as a heat exchanger is a tool that is commonly used in the industrial world. The function of this tool is to cool down a fluid. There are various types of heat exchangers, including shell and tube. The purpose of this research is to design a heat exchanger that is good and correct and has a fairly high effectiveness in accordance with the existing heat exchanger design rules. The object of this research is a heat exchanger with a size of OD in, 16 BWG with stainless steel material which has a counter current type which is used to cool the type of air at a temperature of 80°C to 60°C with the help of an air type fluid also at a temperature of 60°C. 30°C. The effectiveness of the tool is quite large, namely 88.7%.
