Abstract

Third generation (3G) mobile network technology has been present for many years and has wide coverage in various regions of the world.3G network quality is often a problem faced by users.Poor network quality can cause interference in making voice calls, sending messages, and using the internet.Ensuring that the Short Voice Call method provides accurate and representative information about 3G network quality using the short voice call method for 1 minute and iterating 5 times.The results of 3G network quality measurements carried out by walk test in Batu Kuwung Room Hotel Le Dian 1st floor are as follows: out of 3 times of attempted calls made, 2 times were successful and 1 time the call was blocked. The measured RSCP has a low value with an average measured power of -110.31 dBm. The average measured Ec/No was -18.42, falling into the poor category. The SQI MOS also falls into the poor category as it has an average value of 1.96.By using the short voice call method, 3G network quality evaluation can be carried out effectively and potential problems can be identified.

Abstract

This research aims to design a control system for a Peanut Grinder based on a 135 Watt AC Motor, intended to assist small and medium-sized food business entrepreneurs who utilize peanut ingredients. The purpose of this device is to enhance production efficiency in the preparation of peanut-based condiments, replacing the manual and time-consuming process with an automated system capable of sorting peanuts into fine and coarse textures as desired. By utilizing a 135 Watt AC Motor obtained from a washing machine as the main driving component, the design aims to reduce costs by reusing existing components. The control system will encompass mechanisms for grinding peanuts efficiently, ensuring user safety, and regulating motor speed and grinding duration. This research emphasizes environmental friendliness by repurposing unused components. Overall, the proposed Peanut Grinder aims to benefit UMKM entrepreneurs by streamlining production processes and enhancing productivity in the peanut-based condiment preparation.

Abstract

Electrical energy plays a much needed role in people's lives and economic development. Alternative energy potential, especially water energy, is a solution to utilize it as an energy source. Pico Hydro Power Plant is a tool or medium that uses water. At this time a hydro power generation system is being developed that produces electrical energy, one of which is using a pico hydro generator where the flow rate of water can be converted into electrical energy. In the water piping system at home it is used as a source of electricity, namely where the water reservoir as a reservoir for clean water with water conditions that are affected by the water flow rate can drive a pico-hydro generator turbine. In this research, the data collection process was obtained with a process of taking every 2 minutes for 40 minutes, it obtained an average water discharge of 8.75 L/s with a cross-sectional area of ​​0.0531, so the pico hydro generator can produce an average voltage of 8.88 Volts where the output results are step Up for battery charging and the average power is 10.60 watts on the battery using 3 loads and this research can be used for home lighting.

Abstract

Determining the early time prayer is very fundamental for Muslims as it directly relates to the legal requirements of prayer. Prayers are not performed whenever we want, but rather there is a determination of the beginning and end of the prayer time as a guideline for Muslims to carry it out. The Indonesia government sets standards for Muslims to perform the dawn prayer service, by precisely determining the degree of the emergence of the dawn of Sadiq by -200. This study aims to compare the determination of the government's dawn time using different sensors, specifically drone cameras as image sensors. Drones were chosen due to their several advantages. The data generated by the drone is in the form of photos, which are subsequently processed using digital image processing software, called image-J. The data obtained are in the form of mean and standard deviation. All data collected in 1 day is recorded using Excel to form a graph of data which is then carried out by a polynomial approach to find out the cutoff point as the beginning of the dawn of Sadiq which indicates the start of dawn. The method used in this research is using the 4th order polynomial approach and the Sarrus method and the data obtained is the mean value and standard deviation. The conclusions obtained in the image analysis research are that the government's dawn time is 15 minutes too fast, the standard obtained in this study is -14.98° and unlike 2D SQM data, 3D drone data results in more accurate data analysis.

Abstract

Flood is a threat that has significant impacts on communities and the environment. To improve the management of disaster risk, this research takes an integrated approach by utilizing geospatial data from various sources. The main objective of this research is to provide an integrated approach to determining flood-vulnerable area classes. This research focuses on the processing of various geospatial data such as DEM (Digital Elevation Model) imagery, Landsat 8 satellite imagery, Hydrological data based on SHuttle Elevation Derivatives at multiple Scales (HydroSHEDS) water flow accumulation imagery, and Climate Hazards Group InfraRed Precipitation with Station data (CHIRPS) rainfall imagery which are used as data sources to model the flood vulnerable area classification of The Jratunseluna watershed. Landsat 8 satellite imagery is used as a source for landuse land cover (LULC) classification, it is done to score each land category to the level of ability to absorb and drain excess water, the remaining data is used to score the earth elevation, accumulated water flow, and rainfall from the area. The weights and scores are used as the basis values to create a flood-vulnerable area classification model. The result of this research is a flood-vulnerable area classification map generated from a pre-made model.

Abstract

SCADA (Supervisory Control and Data Acquisition) is a system that can supervise, control and acquire data on a plant. This system uses a computer to display the status of sensors and actuators in a plant, display them in graphical form and store them in a database. Generally, this computer is connected to a Programmable Logic Control (PLC) controller through a certain communication protocol (serial communication). This Engineering Practice Report discusses the improvement of the Jakarta flood control monitoring system uses the SCADA system where currently the use of SCADA is only limited to the visual monitoring display of CCTV cameras with water level elevation notifications and risk level indicators arising from the data received. In the design of the SCADA system in pump houses or flood pump sub-polders in locations spread throughout DKI Jakarta that exist today, especially in the current projects implemented, namely JGC Marunda Sub Polder, Adyaksa Pump House and Tipala Pump House.
