Optimalisasi Kapasitas Rooftop PV System Skala Rumah Tangga di Perumahan
Get PDFOne of the renewable energies in Indonesia is solar energy. The geographical condition of Indonesia, which is a tropical country, is one of the advantages it has for applying solar energy. The Indonesian government is gradually regulating the population system for Solar Power Plants (PLTS). The resident system is in demand because of the advantage that it can be connected to the PLN grid and used as an energy reserve. The installation of rooftop PLTS both in government buildings and on the roofs of houses has now become a common trend in the community as a form of participation in the use of New and Renewable Energy (EBT). Before installing PLTS Roofs, it is necessary to determine in advance how much capacity will be installed. This is also related to the community\u27s question, what is the percentage of electricity costs if PLTS roofs are installed in bulk. These designs and calculations are generally carried out with the help of simulations. To discuss these problems, in this article, we will discuss a simulation of the potential for electrical energy generated from rooftop solar power plants in Cilacap Green Smart Living housing. The simulation was carried out with the help of the SolarGIS PV lunar device. Analytical calculations are carried out by software based on input of regional location and solar irradiation. SolarGis will calculate the daily output power generated by the rooftop PV mini-grid and the average monthly and yearly power. The simulation results show that one house with a daily energy requirement of 13 kWh by installing a rooftop PLTS with a capacity of 3 kWp, the demand for electrical energy imported from the PLN network to the house is only 7.8% in one year
Rancang Bangun Monitoring Early Warning System Bencana Banjir Berdasarkan Ketinggian Aliran Sungai Mengunakan Modem SIM900 dan Internet of Things
Get PDFThe 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

PkM Olahan Pangan Hortikultura di Kelompok Wanita Tani Desa Tesbatan
Get PDFThe Community Partnership Program (PKM) activity in the Tesbatan Village Women\u27s Group aims to exploit local potential, namely moringa leaves, corn, chili, tomatoes, papaya and coconut. The local potentials are processed into nutritional products with long shelf life. Thus it will increase the income and health of partner families.
Partners are trained and assistanced during the processing practice of tea products, noodles, moringa cake, corn tortillas, VCO, and sukade. The training was conducted in groups with the andragogy approach that was presented with a ratio of 30% theory and 70% practice. The implementation of PKM has provided training participants with knowledge about cassava diversification, packaging and labeling.
The main target of assistance to farmer groups is to enable the group to independently produce processed products as to increase nutritional and economic value by being marketed around the partner group\u27s residence so that they can continue to carry out housework. In addition to the activities of processed local products, counseling was also carried out about the urgency of stunting on adolescent women and their effects on future generations. Partners are also equipped with knowledge about packaging and label design for the products.
The activity received a very good response, this can be seen from the involvement of partners during the PKM, as well as a positive attitude and high motivation throughout the series of activities indicated by the presence and interest of partners in every discussion, training, and monitoring activity
Peningkatan Pelayanan PMB Berbasis Android di Politeknik Harapan Bersama Tegal
Get PDFCurrently the development of information and communication technology has been approved by the aspects of human life, undeniable in the field of education including the development of mobile technology that presents SmatPhone in various functions that are not only as a means of communication, but also use today\u27s information sources. This creates greater public demand for information on education and encourages Educational Institutions including the Harapan Bersama Tegal Polytechnic to use it as an information media and to register prospective new students based on Android. This study takes the theme "Improving Android-Based PMB Services at the Polytechnic of Harapan Bersama Tegal" with the aim of assisting new students in registering using the SmatPhone device and to assist the Polytechnic of Hope together in processing registration data. This application is a development of an application that was previously still using the Web, then developed into an Android-Based PMB Application by developing using the MIT Ai2 programming that can run on the Android operating syste
Pemanfaatan Augmented Reality Sebagai Media Pembelajaran Protozoa
Get PDFOne of the efforts to improve the quality of education is the use of technology as a medium of learning. The learning media used by XYZ SMA teachers to teach about protozoa in class X MIPA still use graphic images in books. Problems that occur students find it difficult to understand the form, name and function of protozoa animals. To see protozoan animals in real terms, a microscop tool is needed, but there are not many microscopes owned by XYZ SMA. The purpose of this research is to make learning media with Augmented Reality technology about Protists on mobile devices. This application will only display four 3D objects, namely Paramecium, Flagellata, Sporozoa, and Amoeba. The method used by MDLC consists of six stages, namely concept, desing, material collecting, assembly, testing, and distribution. The results of this study are in the form of an Augmented Reality application as a learning medium for the discussion of protozoa. After testing using the alpha test, all buttons / menus run according to their function. Then in testing using the beta test, respondents stated that the application is very good for use as a learning medium

Studi Numerik Kontur Pola Aliran Fluida Pendinginan Pada Mold Injeksi Molding
Get PDFThe conventional cooling process was chosen because of the better estimation of manufacturing times and lower manufacturing costs. One alternative to minimize the decline in quality in plastic products is by using a conformal cooling process. This study will compare the contours of the fluid flow pattern between conventional cooling channels and conformal cooling channels. Case study on a box-shaped product made of PP material which has a melt temperature of 205 ° C. 3D product images were made with Solidwork 2017 software and process simulation using fluent 19.0 software. The results showed that the temperature flow pattern in the conformal channel resulted in a temperature absorption of around 303.2K while the conventional cooling channel was around 302.5K. Then the coolant channel that experiences high pressure drop occurs in the conformal cooling channel around 88888.9 pascals and the conventional cooling channel around 355555.6 pascals
