There are several problems that can interfere with the performance of large-scale PV. One that enhances PV performance is shading on a PV module, that make interferes PV performance. This research studied about the effect of shading on the performance of large-scale PV systems through testing a 9 × 10 Wp miniature PV array and simulation using Matlab software. The use of diodes on a PV module can be done to prevent damage to the PV module due to shading. Through the power-voltage (P-V) and current-voltage (I-V) characteristic curves the effect of shading and the use of bypass and blocking diodes can be determined. Shading effect gave in a decrease in power in the PV module. From the results of this study note that the bypass diode and blocking diode output power generated by the PV module can be optimal.

Android phone is one of the most widely used telecommunications devices today. The exchange of various forms of information ranging from text, sound, images and video through this media is inseparable from the threat of criminal crime through digital data theft. Data security aspects are very important to be considered, one of which is data in the form of text. Text data is commonly used in short message services (SMS), chat in various Android applications or in the use of logins and passwords. This research will create an application on Android for securing text data through cryptographic techniques with a layered algorithm using three types of algorithms namely Caesar, Blowfish and AES Algorithms (Advanced Standard Encryption). This application can run on Android 5.0 (lollipop) or above, which can be used to encrypt and decrypt text messages. The test results show that the results of the initial text that was encoded through the encryption process can be safely returned by the decryption process without the slightest mistake with the original text. The encryption test for capital letters, numbers, and punctuation can be completely decrypted.

The utilization of ozone is commonly applied in various fields, for instance, it is used as a disinfectant for water treatment, disinfecting, sterilizing medical devices and preserving foodstuffs. Ozone is a nearly colorless gas with a characteristic odor that can be detected by humans up to 0.01 ppm. It can be produced by the dielectric barrier discharge method,which is generally used as a method of generating ozone supplied by high voltage or also called high voltage plasma generators. High voltage plasma occurs in the dielectric barrier discharge air gap, as a result of the air failed in maintaining its insulator properties. The power supply used in this study is a parallel resonant pushpull inverter using a flyback transformer. Furthermore, this study did not use an additional magnetic loudspeaker and used ceramic dielectrics instead. 5 types of ceramics and 2 different types of granite and combined the range of air gap were used during examination and research. The research indicates that the best plasma was found in ceramics 3, 5, granite 1 and 2 with an air gap of 2mm. The current discharge in ceramic 1 with an air gap of 2 mm was higher than the others. The highest voltage discharge was on granite 2 with an air gap of 2 mm. Ceramics 3, 5, granite 1 and 2 with an air gap of 2mm had better ozone concentrations than ceramics 1, 2 and 4.

The Child Social Welfare Institution (LKSA) is an institution tasked with providing relief services to meet the standards of living, health, education, and the social needs of both individuals and groups. An LKSA Robbani is one of the institutions that help in handling family and child cases by National Standards for Child Care. In solving child problems, the institution must open the previous case data to determine the appropriate solution, such that the service process becomes long. Therefore, an application software is needed that can help the institution to be faster. The developed system is using the Case-Based Reasoning (CBR) Method. The advantage of this method is how to adapt the solutions of the previous case, as well as in seeking similarity in each case that the most significant similarity value is considered the most similar case. The method is very suitable for building the application. The system that was built had to do a trial before being used by the user. The trial result was carried out of the system with manual calculations using the case-based reasoning method. Furthermore, from the results of the trial, it was produced by 87.5%.

Pekanbaru city is a large area, therefore traffic congestion often occurs due to the density of society’s vehicles. From this problem, it is needed a technology that can exchange information between vehicles. Information Technology that can involve many vehicles with special network types without dependence on an infrastructure is Ad Hoc Network. One type of this network is Vehicular Ad Hoc Network (VANET). VANET is a new concept in enabling communication between Vehicle to Vehicle (V2V). For efficient data packet delivery, VANET requires a routing protocol. In this research, for simulated and analyzed performance is used the Dynamic Source Routing (DSR) and Temporally Ordered Routing Algorithm (TORA) protocol. NS-2 is used to simulated a moved nodes, SUMO software is used to simulated real map of SKA Mall crossroad and parameter the quality of performance routing protocol DSR can determined by End to End Delay, Packet Delivery Ratio (PDR) and Routing Overhead (RO).

Using solar panels as a power plant can reduce the dependence of fuel oil. To work always on maximum power points (MPP), Photovoltaic (PV) requires optimization method. Therefore, the authors are interested in discussing the optimization method of the PV array model using Maximum Power Point Traking (MPPT) with the Perturbation & Observation (P & O) Algorithm and Boost Converter. In this case, PV capacity will be simulated on 10 kWp. That PV consists of 4 strings, which is each strings consist of 10 PV modules. The output of PV modules will be forwarded to the Boost Converter circuit. Boost Converter want is controlled by P&O Algorithm. The voltage and current generated from the PV array modeling will be used by the P&O Algorithm as a reference. The function of P&O Algorithm is to track the Maximum Power Point (MPP) of the PV model. The result of tracking power by P&O Algorithm will be forwarded to Pulse Width Modulation (PWM) circuit as a duty cycle generator. Duty cycle signal will be forwarded to the switching tool contained in the converter circuit. By that control system, PV model expected has maximum power according to the voltage. Based on the results of power test by 1000 W/m2 radiation, maximum power obtained is equal to 9967 Wp with 99.6 % efficiency at a voltage level of 400 volt. Therefore,it can be concluded that the design of the PV Array System using P&O Algorithm and the Boost Converter can work well.

One of main causes of interruption of electrical power supply is the lightning strike on overhead power transmission lines. The lightning performance of transmission line can be determined by value of shielding failure flashover rate (SFFOR) and back flashover rate (BFOR). The object of this study is to create a computer application to compute lightning performance on the transmission lines using Python programming. Pythons package tkinter used for program interface window. Application programming is done by using the concept of object-oriented programming (OOP) using Pythons keyword class.

Mobile Ad hoc Network (MANET) is a wireless network that contains a collection of nodes without infrastructure and interconnected to communicate. MANET works dynamically when a group of nodes moves spontaneously, so the network topology can change quickly and cannot be predicted. It causes changes in wireless network topology according to existing conditions. The node functions in determining the route to be selected. Ad Hoc networks have limited transmission range, so routing is needed to send data over the network. The problem with mobile nodes is that routing must provide a path when the node changes. The speed of a node obtaining information is affected by the routing protocol used in the network. Each routing protocol has different capabilities in network speed, so the discovery routing time for each routing is also different. The selected routing protocols are Ad Hoc On-Demand Distance Vector (AODV), Optimized Link-state (OLSR), and Zone Routing Protocol (ZRP). The study will conduct a comparative analysis of ad hoc network initialization speeds on AODV, OLSR, and ZRP routing protocols. The parameter tested is the speed of routing discovery. After the data is collected, an analysis is carried out by looking at the routing discovery speed of each routing protocol. The test results show that each of the routing protocols examined, the AODV routing protocol, has a faster routing discovery time than the OLSR and ZRP routing protocols.
