<![CDATA[The rainfall in the Cilacap region is high, about 80-100mm in October-March. The high rainfall that causes the overflow of river water is unpredictable. The high water discharge is not realized until the river water overflows and causes flooding. Therefore, a river water level monitoring system is needed to detect river overflows early. This tool uses a solar cell as a power supply. The monitoring system is divided into two points of river water level monitoring system with a distance between points for the laboratory scale stage, which is 100 meters. Sensors that measure the height of river flow are ultrasonic sensors. The sensor results are processed by microcontroller and SIM 900 L module to be sent to the database. When the water level is in the Alert level 3, the buzzer will sound as a warning. The ultrasonic sensor test results have a very small error. Sensor 1 has an average error of 0.00023% and ultrasonic sensor 2 has an error of 0.00016%. The system is able to transmit river water level data that can be accessed through the website.]]>

<![CDATA[Sustainable product design has a role in reducing environmental impacts and can provide economic and social benefits for stakeholders. Design is one way to make improvements and provide an overview of alternative solutions to problems. One of the problems of motorcycle users is experiencing the incidence of punctured tires. This research aims to design a tool to help users of automatic and manual motorcycles when a flat tire occurs. The tool design with dimensions of 160 mm x 190 mm x 100 mm uses a 2 mm iron plate as the mainframe, rubber-type wheels on the front and live caster on the back, and stainless steel for bolts and nuts. Testing the tire leak tool uses three motorcycles with automatic and manual types that have an engine capacity of up to 110 cc, and has a wheel size of 62.09 mm for automatic motorbikes and 65.79 mm for manual motorbikes. The test results showed it function well. The tool is stable and safe when used at a speed of 20 km/hour. The tire leak tool can be used on various types of road surfaces and can withstand passenger loads of up to 65 kg. The trial process was carried out 7 times in the environment around the Purwokerto Telkom Institute of Technology campus with up and down road surfaces and various variations of bends. The tool design is easy to install on leaking wheels and is convenient to carry on the go. A tire leak tool can be used as an alternative for motorcyclists when a flat tire occurs, especially automatic and manual motorbikes.]]>

<![CDATA[The interest of hotel visitors has decreased since the Covid-19 pandemic. So it is recommended that hotels implement Customer Relationship Management (CRM) which has three stages: getting new customers (Acquire), improving customer relationships (Enhance), and retaining customers (Retain). However, hotels currently do not have practical service applications that help to maintain the relationship between hotel management and consumers, so it requires research that implements E-CRM by designing a prototype of web-based Hotel customer service applications. This study aims to standardize hotel customer service applications that implement E-CRM. It uses qualitative research methods by applying the prototype system development method. The research contribution is to make an E-CRM prototype in a hotel customer service application with several features such as complaints, testimonials, promotions, and point redemption. Based on experiments and testing from a user using UAT and interview, the implementation of E-CRM using a prototype of web-based Hotel customer service applications helps the staff to find customer complaints. The promotion feature helps staff add promotional information that appears on the website's front page. Hotel customers can use the feedback feature in complaints, testimonials and redeem points exchange with prizes. In future research, sentiment analysis on hotel customer reviews using a classification algorithm can be carried out.]]>

<![CDATA[The quality of software can be measured. One of them is by its functionality, whether it is suited to user requirements or not. To maintain the quality of the software, testing needs to be conducted during the development stage to ensure that there are no errors or bugs. Tests carried out on the state property maintenance software are focused on the functional module of item replacement by using the black box testing equivalence partitions method. The final result of this test is to know the effectiveness level of the equivalence partitioning method by determining the application test case, initializing the standard input and output partition grade and testing dataset. The final result of the application test shows that the level of effectiveness of the functional goods replacement module is 93.2%]]>

<![CDATA[Resilient, machine processed, shapped aluminium using pulling power for pure aluminium with 4-5kgf/mm2. Aluminium fusion with series 2024-T3 is a metal fusion whose low weldability so it is very difficult to be conducted the welding process because it tends to occur hot cracking or being porous, and precipitation hardening when conducting welding process due to segregation of copper (Cu) fusion subtance. One of welding method to obtain the good aluminium welding result is by using FSW (friction stir welding). The purpose of this research is to find out the shape and type of fracture on aluminium fusion with FSW welding by dealing TTT. The fracture is created from fatik substance test. The reserach method was conducted by welding of plate aluminium fusion 2024-T3 using FSW technique by dealing transient thermal tensioning (TTT). Transient thermal was conducted by resigning heater line with weld tool/pin. The speed of determined FSW welding was 11 mm/minutes and 1200 rpm. The conducted test was fatigue test and factografi test with SEM. The result of the reserach shows that the number of fatik test cycle is 765.250 with sigmoidal curve visually. Then, the result of fractography using SEM shows that the occured fracture is brittle.]]>

<![CDATA[According to UNAIDS until 2018, there are around 690 thousand people with HIV in Indonesia. Until now HIV is a virus that is slow to diagnose, but there are ways that can be used to diagnose the HIV virus. One way to find out whether someone is infected or not is by taking HIV test accompanied by counseling in the clinic (Voluntary HIV Counseling and Testing). Prospective patients feel ashamed during the initial diagnosis of a health examination. To solve these problems, it is necessary to build a system capable to diagnose HIV / AIDS using the best first search algorithm. The result of this study is to be able to facilitate patients checking their health by computerization easily, quickly and precisely, especially about HIV AIDS. Based on the system evaluation of the respondents, RK test results are obtained from the convenient use of the HIV expert system application that has a value of 3.72 with the title of satisfaction. the RK test results from the benefits of using the HIV expert system application has a value of 3.96 with the title of satisfaction.]]>

<![CDATA[Violence is one of the characteristics needed by the ball mill. To get this trait up to now is still done by trial and error so it is very ineffective. Therefore, a study was conducted to determine the parameters that affect the hardness of the ball mill and the optimal level. There are three parameters that are thought to affect ball mill hardness, namely the temperature of raw material (Tm), the initial temperature of the quenching process (Tq) and the final temperature of the quenching process (Tt).]]>

<![CDATA[Domestic economic growth in Indonesia has increased by 5% per year in the four year period of the implementation of the RPJMN (2015-2018). The Department of Manpower and Industry of Cilacap district has had IKM data that have been recorded manually using books. The problem that occurs is the agency difficulty in finding data as well as difficulties in monitoring the development of turnover, production capacity, assets, as well as the number of workers that change very quickly. Based on these problems, it is necessary to create a center-based small and medium industry information system to manage small-based center industries. This research uses the Rapid Application Development (RAD) method. The results of this study are the existence of an information system that is able to manage data of small and medium industries based on centers, the ability to find data quickly, and the ability to monitor developments in terms of turnover, assets, production capacity and number of employees.]]>
