Abstract

Augmented Reality (AR) is a technology that combines objects from the real world and virtual or virtual objects with real-time or direct conditions. The merging of real and virtual objects occurs because of the right technological support while the interactions that are carried out can occur using certain devices. AR is a variation of Virtual Environments (VE), better known as Virtual Reality (VR). This VR technology allows users to fully immerse themselves in a virtual environment. While Augmented Reality technology is developing very fast, many applications in Indonesia use AR technology. This study uses the waterfall system development method, where the research flow will follow the phases of the waterfall. This application is built using Unity and Vuforia. The purpose of this research is an interactive application to make it easier for students and museum visitors to understand augmented reality through mobile devices. So that museum visitors and students can see objects containing information interactively

Abstract

— This research explored the feasibility of corn cob ash-silica fume blend in the production of pozzolanic cement to produce High-Performance Concrete. The cement in concrete was partially replaced by corn cob ash-silica fume blend in 5,10,15 and 20% by weight of cement and was compared to a control mix of 0% replacement. An intelligent mix design, Densified Mix Design Algorithm (DMDA), was used to effectively reduce both water and cement content. In order to create high strength and workability, a polycarboxylate-based super plasticizing admixture was utilized in conjunction with a low water binder ratio of 0.35. Compressive strength was appraised to determine the mechanical properties at days 3,7,14,28 and 56 to determine the optimum percentage replacement and compared to the control at the specific ages. With the optimum percentage replacement, the flexural test was investigated at 28 days. Water absorption and electrical resistivity tests were also investigated as potential indicators of durability. All of the blends that included corn cob ash and silica fume produced a higher strength than the control except 15 and 20%, with 10% replacement yielding a cube strength of 61 MPa at day 56.

Abstract

Photovoltaic (PV) temperature is an important parameter that can influence PV performance. The increase in PV temperature can cause a drop in PV output voltage, which indicates that the PV does not operate optimally. In this paper, a design of an integrated cooling system based on fuzzy logic to control the PV temperature is presented. This, in effect, will potentially ensure that the PV performance is at its maximum condition. In this work, the temperature of the PV is kept constant by attaching a cooling system that carries water inside it. The constant temperature of the cooling system is carried out through a radiator and thermoelectric with electronic control. The experiments are carried out using two 320-watt PV systems; one with the cooling mechanism and the latter without the cooling system as a control. Several important data such as temperature, voltage, current, and radiation measurement in each PV were collected for three days from 10:00 to 17:00 with an interval of 10 minutes for each measurement. The results of the integrated cooling system measurement showed an increase in PV power generation and efficiency of 1.32% compared to the control PV unit. From the results of the study, it can be concluded that the fuzzy logic-controlled cooling system contributed to the increase in PV performance.

Abstract

The food business opportunity is very interesting for home industry entrepreneurs in West Sumatra, a home industry of cassava chips. The step of the cassava chip production process that takes longer time than the other step is the washing process. The cassava washing process is carried out manually because washing device that uses motor drives are not affordable for home industry entrepreneurs. In addition, the cassava washing process makes a physical complaint from the operators. Therefore, this research designs a cassava washer that is affordable for the home industry by considering design methods, ergonomic aspects, and customers' needs. This design is carried out using the Quality Function Deployment (QFD) method to translate the voice of the customer into technical and design characteristics, morphological charts for generating alternative designs, and an objective weighted method for evaluating that alternative. The result of this research is the design of a cassava washer which is more practical because it makes the operator works easier and can save time in the washing process. It is also very affordable, with an estimated cost of production IDR2,397,743.

Abstract

Regarding criticism and suggestions from consumers, it shows that of the 881,140 products sold, there are 22,947 products that are considered manufacturing defects, with an average percentage of defective products per month of 2.71%, with several types of defects submitted by consumers through the survey. This is quite serious because it will provide a bad experience to consumers in using this product. Failure Mode and Effect Analysis (FMEA) is a method used to evaluate system design by considering existing failure modes in a machine or equipment component system and analyzing the consequences for the reliability of the system. Based on the method used, it was found that the highest RPN value was in a case of disability, namely causing itching, with an RPN value of 504, consisting of a severity value of 9, occurrence of 7 and detection of 8, with a percentage of RPN occurrences of 35%. Beased on this result, it proposes improvements to the priority types of product defects and other product defects.

Abstract

The building sector consumes about 30% of the world's primary energy demand. Conventionally, reducing building energy consumption is done through energy saving or energy conservation activities. Nearly zero energy building (nZEB) itself can be defined as a provision that implies a value of energy consumption that is as low as possible or an energy-efficient building, then determines the energy source that is able to meet these energy needs. These strategies can generally be done with passive design, active design, and comprehensive energy management approaches [6]. This article presents an overview of the implementation of nZEB and finds out the shortcomings in terms of strategies and techniques used for different types of buildings and climates. Given the differences in climate and building characteristics, we found that each region has different challenges in applying the nZEB concept.

Abstract

The Indonesian government has also set a target to increase the contribution of renewable energy in the national energy mix to 23% by 2025 and 31% by 2050. In this paper, an analysis of Maximum PV Capacity was used on the transmission network with a minimum loading approach using the Power Factory15.1 simulation. From the simulation that has been done, it can be seen that the placement of two PV location points gets better results than the placement of one PV location point. This can be seen that the feeder load for PV location point of 74.3%, while for two PV location points of 35.8% which value is still within safe limits, but for two PV location points get better results. PV trip state frequency values obtained for single location point and two PV location points get a result of 2% of 50 Hz which is still within safe limits.

Abstract

Microgrids will become common in future electrical distribution networks. Numerous operating modes that occur in microgrids make the development of protection schemes and settings challenging. This paper aims to develop a simple protection scheme for the Microgrid IEC Benchmark without any expensive equipment such as communication apparatus. The scheme consists of directional and non-directional overcurrent relays with standard inverse characteristics. For the simulation tool, Digsilent powerfactory is employed. Four operating modes of the microgrid are applied to verify the relays’ coordination. The results show that the proposed scheme successfully protects the microgrid during short circuit faults with acceptable time margins.

Abstract

The sequence of product assembly affects the efficiency and effectiveness of production because it reduces cycle time and production costs and reduces production errors. The application of artificial intelligence is growing to optimize the problem of assembly sequences of components or products, including genetic algorithms and fuzzy logic. These two models can complement each other to produce the best assembly sequence. This research consists of several stages: model formulation, model analysis, solution, and model verification and validation. A hybrid fuzzy and genetic algorithms model can optimize product assembly sequences more effectively and efficiently. Fuzzy logic can help determine the variables that must be optimized, while genetic algorithms can help find the optimal solution by combining these variables. Experiments using hybrid fuzzy logic and genetic algorithms to minimize assembly cycle time have resulted in product part assembly sequences that accommodate all geometric constraints, including assistive devices.
