Abstract

Clay is silicate frame-based mineral praticle with a diameter of less than 4 micrometers, clay contains fine fused silica and aluminium. The development of clay as an alternative adsorbent is very possible because the clay has a large surface area, high porosity, and high abundance in nature and also relatively inexpensive compared to other adsorbents. The purpose of this study was to determine the ratio of SiO₂/Al₂O₃ content in activated clay. Clay was activated by using hydrochloric acid (HCl) with variable time and concentration of Hydrochloric Acid. Variable concentrations of hydrochloric acid used were 1N, 2N, 3N, 4N, 5N 1000 ml and time variables were 1 hour, 1.5 hours, 2 hours, 2.5 hours, and 3 hours. The best ratio results were shown at 5 N hydrochloric acid (HCl) concentration with 3 hours activation time of 12,26%.

Abstract

Small and Medium Enterprises (SME) product innovation in order to support the concept of green products must be able to convince consumers. Product innovations which have been made that are not in accordance with the tastes of consumers, so the goods are less attractive to consumers. SMEs have difficulties in adjusting products that are environmentally friendly and acceptable to consumers. The high cost in innovating also results in SMEs who hesitate to modify the product. This study aimed to determine, describe, and analyze the effect of green products on the performance of SMEs in Sidoarjo. The first stage was to map green product criterias that affect the performance of environmentally-based SMEs, then analyse the effect of green products on the performance of environmentally-based SMEs. The method used in determining this effect was Partial Least Square (PLS). From the results of data processing, there were factors that influence the performance of environmentally friendly SMEs, namely the green product factor. Then a critical success factor analysis was carried out on the green product factor to determine the strategies that must be taken by environmentally friendly SMEs. The results of the analysis obtained strategy recommendations in improving the performance of SMEs were the strategy of selecting raw materials, choosing energy sources, using the amount of raw materials, and choosing product packaging materials. The strategy was in the context of developing environmentally friendly SMEs so they can improve SME competitiveness.

Abstract

In general, industrial processes have characteristics as multivariable processes where the variables interact with one another which causes poor performance. Quadruple tank is a Multi Input Multi Output (MIMO) system that can be used to analyze dynamics and process control schemes with strong interactions. The design is simple but can represent complex systems in the industry so that a reliable controller can be tested using this system. Tuning controller parameters using Ziegler-Nichols only work well for single loops, therefore detuning controllers are needed using the BLT and Mc Avoy methods. The research method is to make mathematical models and determine the specifications of quadruple tanks. Next make a process simulation and identify the transfer function with the step test method. Interaction analysis using the Relative Gain Array (RGA) method. Tuning controller parameters using the Ziegler-Nichols method is then detuned using the BLT and Mc Avoy methods. Simulation of quadruple tank systems both open loop and closed loop can run well and can be used to test the reliability of PI-PID controllers with BLT and Mc Avoy detuning. Based on IAE values, controller with Mc Avoy detuning are superior compared to controllers with BLT detuning, both at level and temperature controllers.

Abstract

Kimpul can be used as various types of products to increase added value, one of that is biscuits. The advantages of biscuits include long-lasting, also easy to digest. Therefore biscuits can be made as complementary foods for ASI (MP-ASI). MP-ASI biscuits are commonly consumed by children aged 12-24 months. MP-ASI biscuits with the raw material of kimpul flour still need other ingredients to increase the protein content in order to meet the quality requirements, such as cowpea flour. To improve the texture to make it softer, it is used sago flour. Sago flour, which has a high starch content, also functions as an adhesive. This study aimed to determine the quality of the MP-ASI biscuit product of kimpul-cowpea composite flour and sago flour during storage. The research used a single factor RAK, namely the type of packaging (PE pouch, aluminum foil pouch, PE-aluminum foil pouch) and repeated three times. Observation during storage was done in every two weeks for six months. The parameters taken were physical characteristics, water content, Aw, FFA, TPC, and peroxide number. The results showed that during storage, there was a decrease in the quality of physical characteristics, increased water content, Aw, FFA, peroxide number, and TPC. Based on physical and chemical quality, the treatment that experienced the lowest quality decline was P1 (Aluminum Foil).

Abstract

Cane juice is the main raw material in sugar factories. The processing of cane juice to produce the highest quality sugar must be through the proper evaporation process. If the evaporation temperature is too high, the cane juice can be damaged and this will affect the quality of sugar produced. The type of evaporator that is often used to reduce water content in food is falling film evaporator. This study obtained to determine the effect of the flow rate of cane juiceon the temperature distribution at the interface and wall. This research was conducted using Matlab Software and the Runge-Kutta Method. The research variables used were the flow rate of 154, 243, and 301 l/hr and the air flow rate of 4, 8 and 10 m3/hr. The results showed that the smaller flow rate of the solution, the smaller temperature of the solution at the interface with the same position. The temperature distribution on the wall has increased at the beginning of evaporator operation, but then decreased due to evaporation.
