International Conference on Informatics, engineering, Science and Technology, INCITEST 2018

作者： Robecca, J. Sudrajat, D. Study Program of Industrial Engineering Faculty of Engineering and Computer Science Universitas Komputer Indonesia Jl. Dipatiukur no. 112-116 Bandung Indonesia

The purpose of this study is to Minimize the purchase cost for each food from the catering menu. Therefore, raw material inventory control method is needed to plan arrival schedule, order schedule, and the amount of ordering of each foodstuff. The technique of deterMining the amount of ordering (lotting technique) used there are three, namely the least unit cost technique, the lot for lot technique and the least total cost technique. The results of this study indicate that the company can Minimize the cost of purchasing food based on lead time, storage time limit, and optimal lotting techniques. Lead time is the period between the order to the delivery time, the storage time limit is how long the best time required for the quality of foodstuffs are maintained, while the lotting technique is the optimal size of order quantity. The lotting technique chosen for each type of food material is different. The cost of purchasing the food consists of the price of the foodstuff, the ordering fee for the type of material and the storage cost for the type of foodstuff. There are 16 types of foodstuffs with the cost of purchasing the smallest raw material with the lot for lot techniques. There are 29 types of foodstuffs with the cost of purchasing the smallest raw materials using the least unit cost techniques. And 10 types of foodstuffs with the least total cost technique as a lotting technique with the purchase of the smallest raw material. Of the 55 types of food raw materials, the company was able to save the cost of purchasing groceries of 33,006,371.75 IDR per month. Of course, in order to apply this planning, the company must provide facilities in order to extend the life of the foodstuff in accordance with predeterMined lead time and to ensure the quality of the foodstuff is guaranteed. © Published under licence by IOP Publishing Ltd.

Effect of Temperature and Starter Concentration on the Fermentation Process in Making MOCAF

引用

Journal of Physics: Conference Series 2020年第1期1500卷

作者： Muhammad Yerizam Suri Andayana Utari Oktavia Industrial Chemical Technology Study Program / Chemical Engineering Sriwijaya State Polytechnic Palembang Indonesia

This research aims to determine the optimum conditions with variations in temperature and concentration of Lactic Acid Bacteria (BAL) starter in fermentation in the process of making mocaf flour. Fermentation of cassava is carried out using a fermenter equipped with a thermo controller and tubular heater. Heater is used to increase the temperature connected to the temperature controller (thermo controller) so that the fermentation process runs in optimum conditions and get good quality of mocaf flour according to SNI 7622-2011 standards. The fermentation process was carried out anaerobically with and varying the temperature of 30 and 33°C and the concentration of the lactic acid bacteria starter were 0.06%, 0.12%, 0.18%, 0.24% and 0.3% with fermentation time during 24 hours. The results showed optimum conditions of cassava fermentation at a temperature of 33°C and lactic acid bacteria starter concentration of 0.3% obtained mocaf flour protein levels of 12.87%.

Transesterification Condition of Crude Palm Oil to Biodiesel Using Solid Catalyst Zeolite/NaOH

引用

IOP Conference Series: Materials Science and engineering 2020年第1期854卷

作者： E Kurniasih P Pardi Adriana Department of Chemical Engineering Study Program of Industrial Chemical Technology Polytechnic State of Lhokseumawe Aceh Department of Chemical Engineering Study Program of Oil and Gas Production Polytechnic State of Lhokseumawe Aceh

The use of NaOH as a catalyst for biodiesel production has long been used and provides high conversion conversions. Homogeneous NaOH phase during the transesterification reaction causes soap to form at the end of the process. Soap is diseparasi from biodiesel by washing and decantation techniques. The presence of soap can reduce the quality of biodiesel, especially at the flash point of biodiesel. Heterogeneous catalyst zeolite / NaOH is synthesized from natural zeolite and NaOH through the impregnation method. Natural zeolite is contained in natural rock obtained from Ujong Pancu, Aceh Besar. The synthesis of natural zeolite catalyst was initiated by activating zeolite powder with 4 M HCl for 10 hours at 90oC. Activated zeolite was impregnated using 2.5% NaOH at a ratio of 1: 2 (w / v) at 90oC for 2 hours. Application of zeolite / NaOH in transesterification reaction using crude palm oil off grade. The results showed that the use of zeolite / NaOH can prevent the formation of soap with characteristics that have met SNI 04-7182-2006 standards.

Estimating the opportunities of ester content improvement through variation of NaOH, KI And KIO3 developed impregnators on activated natural zeolite catalyst for methyl ester synthesis

引用

IOP Conference Series: Materials Science and engineering 2020年第1期725卷

作者： E Kurniasih P Pardi Departement of Chemical Engineering Study Program of Industrial Chemical Technology Polytechnic State of Lhokseumawe Aceh Departement of Chemical Engineering Study Program of Oil and Gas Production Polytechnic State of Lhokseumawe Aceh

The Content of esters are the number of compositions of esters formed after the esterification and / or when transesterification reaction takes place. Esters are formed by breaking up the alkyl acid carboxylic group of fatty acids or triglycerides which react with methyl groups from methanol. To increase the reaction rate, heterogeneous catalysts were synthesized using impregnators NaOH, KI and KIO3. The impregnator is carried out in the framework of natural zeolite with a concentration of 2.5% (w/v). The zeolite framework was previously activated using 6M HCl solution for 10 hours at a temperature of 90°C. To strengthen the impregnator bond on a heterogeneous zeolite catalyst, calcination was carried out at a temperature of 600°C for 4 hours. Heterogeneous catalysts were tested on biodiesel production using a transesterification reaction. The transesterification reaction was carried out at a temperature of 65°C for 2 hours based on crude ester with 5%-10% (w/w) heterogeneous zeolite catalyst ratio shows the percentage decrease in free fatty acid content of 74.05% for zeolite/NaOH, 75.01% for zeolite/KIO3 and 75.77% for zeolite/KI. Based on the results of gas chromatography analysis, it was found that zeolite/KI catalysts of 77.1591.86%.

Experimental investigation of thermal behavior in an active type solar water heater based on phase change material using solar simulator

引用

AIP Conference Proceedings 2020年第1期2296卷

作者： Muhammad Nadjib Suhanan Joko Waluyo 1Doctoral Study Program Department of Mechanical and Industrial Engineering Faculty of Engineering Gadjah Mada University Yogyakarta Indonesia 2Mechanical Engineering Study Program Faculty of Engineering Universitas Muhammadiyah Yogyakarta Yogyakarta 55183 Indonesia 3Department of Mechanical and Industrial Engineering Faculty of Engineering Gadjah Mada University Yogyakarta Indonesia

The weakness of an outdoor solar water heater (SWH) experiments is the difficulty in determining its thermal behavior. The fluctuation of solar radiation intensity causes the supply of energy received by SWH also fluctuate. The result is that the thermal behavior of the SWH cannot be known for specific parameters. This paper aims to investigate the thermal behavior of an active type SWH containing paraffin wax using the constant heat flux method. A phase change material (PCM) inserted into the capsule. The capsules were arranged in a tank to form a heat exchanger (HE). The thermocouples were mounted both on the waterside and the PCM side. The solar simulator installed on the top of the collector, and the SHW system placed indoors. The heat flux and water flow were set at 1000 W/m2 and 2 LPM, respectively. The temperatures of water and PCM for 143 minutes charging recorded. The data obtained were used to analyze the thermal behavior of water and PCM. The results showed that the average heating rate of water and PCM was 0.227 °C/min and 0.205 °C/min, respectively. The value of this adjacent average heating rate shows that HE has functioned well in removing heat energy from water. The accumulated thermal energy produced was 13.08 MJ. Indoor experiments can reveal the thermal behavior of the SWH-PCM systems.
