Dr. Setiabudhi No. 229 Bandung 40154 West Java - Indonesia Tel. 022-2013163 Fax. 022-2013651 Abstract The incessant development of infrastructure in Indonesia is one factor in the increasing role of the construction sector in the Indonesian economy. This can be seen from the large percentage of the construction sector to GDP of 10.60% in the third quarter of 2019. One of the improvements is found in technological developments in the construction sector. Technology in the construction sector has an influence on the development of modern equipment that can increase the productivity of construction work, including ceramic installation work. The quality of the ceramic installation work is of concern to the constructor because the results that are done depend on the skills and abilities of the ceramic craftsman. The effort made is by making ceramic installation tools that have been designed to lift and level the ceramics at the time of ceramic installation work. Vaporcelain is made using the principle of the vacuum system and the grade system of the nivo and also made using easily available ingredients. Vaporcelain as a product is created with the aim of facilitating the finishing work of ceramic installation in a building, increasing the results of ceramic installation according to standards, and increasing the productivity of ceramists.

METHOD OF SUGAR PRODUCTION FROM ARROWROOT STARCH : A REVIEW Enjang Rohman (a), Rama Tiyana (a), Sarah A. N. W. Al Falah (a), Mustika N. Handayani (a) a) Study Program of Agroindustry Technology Education, Faculty of Technology and Vocational Education, Universitas Pendidikan Indonesia Abstract Sugar production from sugar cane, palms, and beet plants could not been able to meet domestic sugar needs in Indonesia. Moreover, there is a shift in sugarcane as a raw material for ethanol. An alternative solution to this problem is sugar production from other sources such as starch, which is widely found in local Indonesian tubers. Arrowroot tubers (Maranta arundinacea L.) are minor tubers that have potential to be used as raw material for sugar production because they contain 19.40-20.96% starch. The purpose of this study was to explore a method of producing sugar based on arrowroot starch. The method used was literature review. In general, the production of arrowroot starch-based sugar consists of extraction, hydrolysis, purification, and crystallization. Starch extraction can be done using wet or dry methods. Hydrolysis aims to break down starch into simple sugars which can be done by acid hydrolysis, enzymatic hydrolysis or a combination of both. Purification aims to remove impurities from sugar components through defecation, sulfitation, or carbonation methods. Crystallization aims to obtain sugar crystals which can be done by adding anti-solvent or cooling. Productivity and quality of arrowroot starch-based crystal sugar depend on the sugar production method used. Keywords: Arrowroot Starch, Sugar, Crystallization, Extraction, Hydrolysis, Purification.

One of the media that can be used by blind children in learning to recognize braille characters is Dynamic Braille Display media that can work according to instructions from the user. However, the media is still difficult to find because they have to order abroad for around 3600 euros, the equivalent of about 53 million rupiahs. In addition, this device is limited to the Latin writing systems letters and punctuation marks. It cannot be used to generate Arabic letters or the so-called Hijaiyah characters. This study aims to produce Dynamic Hijaiyah Braille Display media with voice features and integrated android, which can be used as a medium for recognizing Arabic letters for blind children. Therefore as the solution, we offer the Dynamic Hijaiyah Braille Display media, which has the advantage of Arabic letters in the form of braille characters and can sound according to the letters pressed. Learning can also be monitored by parents or teachers virtually through the android application. In this research, an electronic system is designed to accommodate two braille character cells for Arabic letters and their punctuation. The device is also equipped with voice features and an integrated android application. This system was tested with the results of being able to generate two patterns with a functioning solenoid and integration with Android devices using the Firebase platform. Furthermore, the voice feature can be operated properly according to the Hijaiyah character being learned.

Dr. Setiabudi No.229, Bandung 40154, Indonesia Abstract Polylactic acid (PLA) is an environmentally friendly plastic raw material. However, the synthetic lactic acid raw materials needed are relatively expensive. There is an alternative solution to produce lactic acid from other natural resources that are abundant and untapped, such as tofu industrial solid waste, namely tofu dregs. This study aims to explain the potential of tofu dregs as a raw material for Polylactic Acid. The data collection method used was literature review. It is known that Lactobacillus plantarum can hydrolyze the starch content in tofu dregs into lactic acid. Furthermore, lactic acid is polymerized into Polylactic acid by using the Ring-Opening Polymerization method to produce Polylactic acid. The starch content of tofu dregs is potential to be processed into Polylactic acid.

ANALYSIS OF ALTERNATIVE SOLUTIONS FOR IMPROVING VOLTAGE PROFILE DUE TO OVER LOADING INTERCONNECTION SYSTEMS 150 KV Tasma Sucita, Yadi Mulyadi Departemen Pendidikan Teknik Elektro Universitas Pendidikan Indonesia Abstract Voltage profile has a very important role in the distribution of electricity from generation sources to consumers. This research was conducted at PT. PLN APB West Java with the subject of the power flow study conducted to determine the voltage profile, active power flow and loading on the subsystem. The purpose of this study is to determine the voltage profile with a power flow study and understand the concept of operating patterns in a 150 kV transmission system during daily peak load conditions. The reason for this research is to evaluate the extent to which subsystems connected to the looping system can operate without problems that can disrupt the quality and reliability of the network on each busbar. So it is useful in the operation of the electrical system so that the voltage value is still within the reliability criteria of the subsystem. The method in this research explains the study of power flow in a 150 kV electrical system under normal conditions and in the working pattern conditions when the generator is only operating 1 unit, until it does not operate all (0 units) even the entire load is simulated using ETAP Software with analysis method Gauss-Seidel. Research findings with power flow studies are expected to obtain a solution for the system under conditions of low voltage disturbances (under voltage) due to more loading until returning to normal conditions.
