Abstract

This study aims to determine the effect of the amount of yeast and the length of time of fermentation on % yield of cilembu sweet potato bioethanol produced from the fermentation process. The stages of the research method include: sample preparation of cilembu sweet potato, hydrolysis process, fermentation process and bioethanol purification. Sample preparation was carried out by cutting, washing, drying and grinding. The hydrolysis process uses the acid hydrolysis method, namely 21% HCl. Yeast Saccharomyces cereviceae was used in the fermentation process with 5, 6, and 8 days of fermentation time and 5 grams and 6 grams of yeast mass variations. Meanwhile, the distillation method is used in the bioethanol purification process. Next, the percent yield of the bioethanol produced is determined. The results showed that the yield of bioethanol using 5 grams of yeast with each fermentation time was 5 days: 0.86%, 6 days: 1.94%, and 8 days: 0.97%. While the % yield of bioethanol used 6 grams of yeast each with variations in fermentation time of 5 days: 1.25%, 6 days: 1.69%, and 8 days: 1.6%. The highest bioethanol yield was found on day 6 with the use of 5 grams of yeast.

Abstract

Cinnamaldehyde (C9H8O) makes perfume, aroma enhancers in making candy, soap, and medicine. Factory designed with a capacity of 20,000 Tons/Year. The factory, located in Gresik Industrial Area, East Java, operates 330 days a year with 24 hours/day production. They were making Cinnamaldehyde using the Aldol Condensation process by reacting Acetaldehyde and Benzaldehyde with a Sodium Hydroxide catalyst in the reactor at a temperature of 70oC and a pressure of 4.7 atm with a conversion of 85%. The reaction is exothermic, so to maintain the temperature of the reaction, water cooling is needed. Then Cinnamaldehyde is neutralized with H2SO4 in the neutralizer, and Cinnamyldehyde is further separated in a distillation tower. The results of the economic analysis show that the Cinnamaldehyde plant requires fixed capital (Fixed Capital Investment) of IDR 525,828,918,487 and Working Capital Investment of IDR 92,793,338,557. This factory has a Return Of Investment (ROI) before tax 64.45% and after-tax 73.24%; Payout Time 1.37 years, Shut Down Point (SDP) 61,96%, Break Event Points 44.2%, and Internal Rate Of Return (IRR ) 19.22%. Based on the economic review, it can be concluded that the Cinnamaldehyde factory is feasible to build.

Abstract

Ammonium Nitrate is a raw material for the manufacture of chemical fertilizers that are needed in the agricultural sector. Sadly. Domestic production of ammonium nitrate is still not able to meet domestic needs, so imports are the solution to meet these needs. Until now there are four general methods that are generally used to produce ammonium nitrate, among which there is the vacuum crystallization method. In the process of making ammonium nitrate with a production capacity of 150,000 tons/year, the reactor acts as a place for reacting raw materials in the form of ammonia and nitric acid. The reaction that occurs is exothermic with an operating pressure of 4.4 atm and a temperature of 60 oC. The reactor used is a mixed flow reactor in the form of an upright cylinder with a standard dished top lid.

Abstract

The availability of non-renewable energy has recently been running low, which has an impact on electrical energy. One of the efforts to utilize renewable energy is by utilizing the kinetic energy of water. Water energy can be transferred into other forms of energy such as mechanical or electrical using a water turbine. The Contra Rotating type turbine is suitable for use by utilizing a small water flow rate. This research is a previous development by changing the slope of the blade angle on the turbine. The results showed the high and low values ​​of the contra rotating turbine rotation due to the influence of the tilt of the blade angle affect how efficiently the turbine captures power from the water flow. At the lowest blade angle, which is 15O degrees, the highest rotational speed is 240.3 rpm. The greatest power is also obtained by a turbine with a blade angle of 15O with a value of 0.5176 watts, and from the calculation of the performance efficiency of a contra rotating turbine with a blade angle of 15O, the highest value is 0.598%, so it can be concluded that the blade angle affects the performance of the contra rotating small hydro turbine.

Abstract

Batu City is one of the cities in EastJava Province which has a tourist destination that is usually visited by immigrants because of its culture, natural beauty and friendly citizens. Located at the intersection of Jalan Diponegoro and Jalan Gajah Mada, Batu City, there is Batu Square which describes one of the holiday destinations in the city center. With this location, and the increasing number of residents, it also increases the need for transportation facilities to support activities, thus causing an increase in the number of 2-wheeled and four-wheeled transportation equipment that requires parking space. With this background, the researcher aims to understand the situation of the existing parking capacity, parking demand, and parking space circulation. To find out, researchers used information in the form of primary data and secondary data. While the results obtained before the pandemic were the number of parking spaces that were still lacking, this was known during the 7-day survey at 15.00 – 21.00, because at that time there were many parked 2-wheeled and 4-wheeled vehicles, so that parking needs exceeded normal capacity. , while the average parking space for motorbikes is 852 parking spaces and the average car parking space is 272 parking spaces, so with this condition it is considered that the parking facilities are not feasible and need to be rearranged. As for the irregular circulation of vehicles, further arrangement is needed.

Abstract

The pre-design of the paper mill as it will be designed is based on a capacity of 18,000 tons/year, with bagasse mainly containing cellulose. The location of this factory was established in Sukosari Village, Djatiroto District, Lumajang Regency, East Java. The factory's location was chosen to be close to the source of raw materials, namely bagasse (bagasse) which is the waste of a sugar factory in the Lumajang area, including PG Jatiroto. Paper mills work for 300 days a year based on the production process every day. The method used in papermaking is one of the soda processes based on several stages, including the pre-treatment stage, cooking as can be used to remove lignin using 10% NaOH solution at a temperature of 170°C and a pressure of 8 atm. Next in the bleaching stage is the bleaching process with the help of H2O2 at a temperature of 70°C and a pressure of 1 atm, and the last stage is post-treatment which can form sheets of paper. The primary tool used is a bleaching tank for the bleaching process with a capacity of 5,908,5096 kg/hour, and after calculations, the bleaching tank is obtained with SA 240 Grade M type 316 stainless steel construction. A vertical stirred paddle vessel with a head and bottom in the form of a standard dished, type Double Welded Butt Joint welding, and a corrosion factor of 1/16 inc. The bleaching tank has a height of 3.7198 m, a diameter of 1.8962 m, a shell height of 2.9718, a design pressure of 17.606, and a residence time of 70 minutes.
