Abstract

The development of UWB technology is very helpful in supporting high-speed data access. UWB offers a solution for large capacity for wide bandwidth. The frequency range for UWB systems between 3.1–10.6GHz will cause interference to wireless communication systems via wireless local area networks (WLANs) for IEEE 802.11a operating at 5.15–5.35GHz and 5.725–5.825GHz. This research aims to obtain a design of a rectangular printed monopole patch microstrip antenna and a slit using the Defected Ground Structure (DGS) technique to obtain bandwidth optimization on the UWB spectrum. For the implementation of the antenna design, the simulation method is used with the support of the RT/ Duroid substrate material. Realization of the design with the results of a manufactured antenna prototype with a minimalist size. The simulation and measurement results of the Absolute UWB bandwidth parameter at return loss < -10 dB (VSWR <2) the measurement value is 600MHz narrower than the simulation and for fractional bandwidth the measurement value is narrower by 0.21%. Resonance at the 5.2GHz frequency produces polarization with a gain value of 3.29dBi, omnidirectional and vertical polarization. As a prototype antenna to support the application of indoor wireless access communication devices that are low profile, compact with minimalist dimensions.

Abstract

The unpredictable weather changes in Indonesia cause various problems for the agricultural sector. One of which is the decline in productivity of farmers' crops up to 40% which is caused by non-optimal environmental conditions during the plant growth process. To be able to adapt to these conditions, it is necessary to have an optimal system of environmental conditioning for plant growth. In this research, a screenhouse temperature and humidity conditioning system was designed for the growth of tomato plants as a horticultural commodity with high potential and high economic value in Indonesia. The system design is modeled and tested through simulation on Vensim software by varying the furnace capacity by 4oC/hour, 6oC/hour, and 10oC/hour in order to see its effect on the internal screenhouse temperature and heating duration. Based on the simulation results of system design, the heating rate and duration for each furnace capacity variation are 4.74oC/hour (135 minutes per cycle), 6.9oC/hour (75 minutes per cycle), and 11.76oC/hour (45 minutes per cycle). The furnace capacity value of 10oC/hour is considered to be optimal and more energy efficient because it only requires a heating process for 180 minutes per day to maintain the screenhouse internal temperature in optimal temperature range for tomato plant growth, which is 18 - 24 oC with an offside value of ±0.5 oC. The stable cooling rate value for this system is in the range of 1 – 1.8oC/hour.

Abstract

Wind energy that can be utilized into electrical energy certainly requires sufficient wind speed so that the wind turbine can rotate and produce mechanical movement in the form of rotational torque which can then be converted into electrical energy. Before the application of the technology is carried out, this study is needed to examine the potential of wind energy produced in Siman Village, Lamongan Regency. To produce a power profile from wind energy sources, wind speed measurements are first carried out, followed by mechanical modeling and wind turbine electrical modeling. The maximum electric power generated from the simulation of electrical energy conversion using a wind turbine is 11.94 Watt with a maximum wind speed of 3.5 m/s. If converted in energy units, then in a day the wind energy that can be extracted into electrical energy is 286.56 Watt.h. When compared with the daily electrical energy needs in the household sector (9364 watt.h) the electrical energy generated through modeling is able to meet 3.1% of electricity needs in a day.

Abstract

A Handheld portable 3D Scanner is an optical-based tool that can be gripped by hand and moved from one place to another. This tool is used to scan part’s surface and produce a 3-dimensional representation in the form of a point cloud. The use of 3D Scanners has grown significantly in recent years, especially in applications in the metrology, industrial manufacturing inspection, and reverse engineering. Apart from the ease of use and flexibility of use, as an optical-based tool with triangulation principles, Handheld Portable 3D Scanners have limitations in scanning the geometric shape of a narrow hole or slit. The specifications published by the manufacturer do not fully describe tool’s performance  in this regard. For this reason, an evaluation of the performance of the Handheld Portable 3D Scanner is carried out by determining the error of measuring holes on the workpiece with variations in depth and diameter. As a reference value, the results of the Coordinate Measuring Machine –CMM measurement are used. . The study result show that handheld 3D scanners generally have an error in measuring the diameter and measuring the depth of the hole, above the specification of 0.03 mm. In holes with a diameter of 1 mm, the handheld 3D scanner has a relationship between the error of measuring hole’s diameter and hole’s diameter with the regression equation: y=0.037x-0.54. En values categorized as "outliers" were found in holes with a diameter of 1 mm with a depth of 0.5, 1, 2, 4 mm and holes with a diameter of 2mm with a depth of 4 mm.

Abstract

The technology  of adding manufacturing or 3D printing is one of the main issues in the concept of technology 4.0. The construction design of the 3D printing machine and the deflection of its construction significantly affect the accuracy of the dimension and shape the printed product. The study aims to obtain a construction design of a cartesian type 3 D printing machine based on fused deformation modelling, and to verify the maximum value of the deflection of the machine axis. The study method used VDI222, calculation analysis, and Finite Element Analysis (FEA) simulation using CAE Solidworks software to verify the strength and deflection of the machine design construction. The study results show the construction design of 3D printing machine has been obtained according to the requirement. The verified maximum deflection value is 0.036 mm, hence the maximum error in the dimensions and shape of the printed product for each layer will still be within the standard tolerance. In addition, its maximum deflection value is verified within the radial clearance value of each determined machine axis bearing.

Abstract

Currently, it is hoped that information technology will provide many conveniences for consumers. Because of its ease of use, information technology makes it easier to process data that was previously done manually to become systematic. A newer feature is the use of applications that have been systemized in Android on smartphones. Mitra Karya Cooperative is one of the cooperatives that performs data processing using the Microsoft Excel application, so there are still problems that occur regarding the completeness and security as well as the data distribution process. Building an Android application to process customer data, savings data, and online lending data at the Mitra Karya Cooperative is the goal of this research. The spiral system development methodology, which includes phases of customer communication, planning, risk analysis, engineering, construction, and disposal as well as customer evaluation, is used in this study. While the model used by the author to visually design the application uses the UML (Unified Modeling Language) model. The Kodular framework and Airtable database are used in the development of Android-based applications. The outcome of the research is an android-based application that can be used to assist Mitra Karya Cooperative in resolving issues related to the cooperative data processing process, which consists of processing customer data, processing deposit data, and processing customer loan data online using an Android device.

Abstract

Fresh fish is sensitive to storage temperature. Temperatures above 2 °C accelerate the growth of bacteria and cause spoilage. The optimal storage temperature for frozen fish is -20 °C. Reefer container with a closed cooling system serves to preserve by maintaining the temperature of frozen fish. The problem of this research is the uneven distribution of cold air in the reefer containers of the train, thereby reducing the quality of frozen fish. The purpose of this research is to increase the even distribution of air, velocity, and pressure in the reefer container of the train. The solution to the problem is simulation and analysis of the condition of the reefer container train using Computational Fluid Dynamics (CFD). Reefer containers without guide plates are simulated to find out the area of the train reefer containers that are not evenly distributed. The distribution of air in the reefer container of the train is improved even by the addition of guide plates with variations in angles of 40°, 50°, and 60°. This research produces qualitative data (velocity contour and pressure contour reefer container) and quantitative (average velocity and pressure). The results of this study are CFD simulation data of uniform distribution of air, speed, and pressure on the reefer container train with a 40⁰ guide plate.
