Neighborhood RW<br>XXIX The GMA III housing estate is classified as new, the area is quite large and has a relatively<br>dense population. The current condition is the problem that is often faced by RT and RW heads in<br>carrying out their main duties and functions (tupoksi), namely in serving their citizens related to<br>various administrative requirements less than optimal, due to one side being unable to leave their<br>rights in carrying out their activities as individuals and heads families so that services to their citizens<br>cannot be ontime but only at certain times, conditions like this clearly have an impact on impeded<br>smoothness in carrying out the tasks of the village or village government in development and society.<br>In addition, in providing important information / news to its citizens, it is also waiting for routine<br>community meeting every month. In an effort to carry out its duties, functions and to organize its<br>environment, RT V RW XXIX housing GMA III needs to make changes and breakthroughs. One of<br>them is the need for support in the use of information technology to help, manage and manage their<br>tasks in order to improve services to the community. In this study he made an IoT-based RT<br>Management Information System to optimize its services.</p> Solikhin Solikhin, mr Martono Martono, mr ##submission.copyrightStatement## 2019-12-04 2019-12-04 18 2 18 24 TI Pengembangan Sistem Informasi Pendaftaran Seminar Kerja Praktek Program Studi Sistem Komputer Universitas Surakarta 1,3 Berbasis Codeigniter 3 http://jurnal.politama.ac.id/index.php/jp/article/view/271 <p>Based on the results of practical work in the administrative office of the Computer System Study<br>Program at the Faculty of Electrical and Informatics Engineering, University of Surakarta, the author<br>has made a web-based practical work seminar registration information system using the PHP<br>programming language assisted with framework codeigniter 3. The system is still intended for<br>administrative staff and have not been given registration facilities for students online, in connection<br>with this case students who want to register for practical work seminars still have to come to program<br>administration. Based on these problems, the author is motivated to develop a practical work seminar<br>registration information system by adding facilities so students can register for practical work<br>seminars online. Making this information system requires MySQL and PHPMyAdmin as a system<br>database. For system design, the author uses CSS and bootstrap to make the display of information<br>systems interesting, and for the main programming language the author uses the PHP programming<br>language that is assisted with framework codeigniter 3. The stages in making this information system,<br>begins with analyzing the system that is running and analyzing system requirements. The second stage<br>is done designing the system database. The third stage is to design a system display design. The fourth<br>stage lists the programs and compiles the program. The fifth stage is testing the system, from the<br>results of the test it can be concluded that the practical work seminar registration information system<br>is going well. The last step is to install the program into the hosting server. The addition of registration<br>facilities for students facilitates the online student registration process. The registration proof output<br>and student registration report are also more effective and efficient.</p> Dwi Prihtapambudi, ms Budi Nugroho, mr Cicilia Puji Rahayu, ms ##submission.copyrightStatement## 2019-12-04 2019-12-04 18 2 25 33 TI Rancang Bangun Sistem Kendali Dan Monitoring Rumah Tinggal Menggunakan Smartphone Berbasis Mikrokontroler Di Sukaharja Kabupaten Ketapang http://jurnal.politama.ac.id/index.php/jp/article/view/272 <p>A recent technological development in many developments such as small shophouses and<br>residential houses has made practitioners create ideas that are very useful for society in life today,<br>especially the number of theft cases that target residential houses. The occurrence of the theft was due<br>to a lack of security, causing the thieves to intend to look for opportunities to enter the house. To<br>overcome this problem arises the design and control systems using a smartphone-based<br>microcontroller. The open source operating system on an Android smartphone can be used to make a<br>light controller and servo motor application to play CCTV using Arduino UNO (Microcontroller AT<br>Mega 328). Android applications are used as input commands to the microcontroller circuit via a<br>bluetooth module connector. The servo motor controller system for playing CCTV uses 3 output pins<br>on the microcontroller, and for the light controller system uses output pins 3,4,5,6,7,9,10,11,13 on the<br>microcontroller, the light controller system pins are connected with 2.2K ohm resistor for lights with a<br>current (DC), and for lamps with a current (AC) using relay modules, relay modules function as a<br>switch. The results obtained by the servo motor can rotate 180ยบ and 9 lights can work controlled with<br>an Android smartphone.</p> Syarif Ishak Alkadri, mr ##submission.copyrightStatement## 2019-12-04 2019-12-04 18 2 34 51 Sistem Informasi Persediaan Barang Pada UD.

Improved services are shown by improving hospital management, such as the management of existing resources optimally. In management, planning is the initial activity stage and is very important because it can define the goals, strategies, and directions needed. The number of patient visits is fluctuating and the exact number cannot be predicted, causing the planning that has been made to be inefficient. In an effort to anticipate these problems and support planning management, it is necessary to estimate or predict. In this study using the Fuzzy Time Series method with Average-Based Length Algorithm which is packaged in a computing application to predict the number of patient visits Central Surgery Installation at Permata Medika Hospital Semarang. The algorithm is able to determine the effective interval length, so that it can provide predictive results with a good degree of accuracy, thus the prediction results can be used in supporting decision making for the leaders of Permata Medika Hospital Semarang quickly, effectively, and accurately.</em></p> Martono Martono Barkah Hendrardi ##submission.copyrightStatement## 2019-12-04 2019-12-04 18 2 63 71 Investigasi Material Baru Sebagai Pengganti Part Dies Import http://jurnal.politama.ac.id/index.php/jp/article/view/281 <p><em>The special material used as a stamping process (dies) cutting tool is currently needed by the manufacturing industry. Many companies use import materials as part of the production process even though many of the same material properties are found in the domestic market. The purpose of this study is to observe changes in the microstructure and improvement in mechanical properties of imported dies and SKD-11 steel components as a replacement. This research was carried out by heating SKD-11 steel specimens to austenitic temperature of 850oC with holding time for 1 hour and 2 hour then cooled with water. The specimens that have been subjected to heating and cooling are then subjected to rigorous and microstructure testing. Microstructure observation results show that the longer the holding time, there are more martensitic carbide content which can result in harder material. The results of SKD-11 steel hardness testing without heat treatment (224.3 HV), with a holding time for 1 hour (559.7 HV), and for 2 hours (580.9 HV). The hardness test results show that with increasing holding time the hardness value will rise and reach the highest value at a holding time of 2 hours (580.9 HV). The conclusion from the data shows that SKD-11 steel experienced an increase in violence but could not match the hardness value of imported dies materials.</em></p> Moch.
