Abstract

The presence of tourist buses is considered to be a factor in Yogyakarta’s traffic congestion in long holiday season. Research was conducted to plan a tourism transportation, called Trans Jogja Wisata that is integrated with other public transport services to accommodate tourist movement from park and ride locations to tourist attractions. Data collection was done by carrying out surveys and interviews at a parking location in Yogyakarta. The data collected included tourist destinations, bus gateways to Yogyakarta, and environmental conditions. Based on the analysis results for planning Trans Jogja Wisata’s integration with existing public transport, there are four designated routes that can be used to accommodate tourists in getting to their destinations: Route 1, Route 2, Route 3, and Route 4. These routes are fully integrated with the Trans Jogja bus system, becak or pedicabs, andong or horse drawn carriages and Si Thole mini buses.

Abstract

Inefficiency of service and the waiting time can occur in inpatient services, especially in VIP rooms. Reduction in waiting lists for patients entering the VIP room is carried out by increasing the bed capacity and the allocation of health workers. The study was conducted by modeling the service system in hospitalization, which began from the patient service at the Emergency Room (IGD) until service in the VIP room of a hospital in Sukabumi. The model was built with 2 scenarios, scenario 1 was designed to improve the performance of the IGD by adding beds and health workers so that patients had an alternative choice in class 1 before getting service in the VIP room, and scenario 2 was designed by not changing the system in the emergency room, but adding 10 VIP rooms. Scenario 2 is a solution and can visually improve the VIP service system by reducing the waiting time by 50.55 hours, with the investment value of net present value (NPV) > 0 and internal rate of return (IRR) 32.2%, against the Minimum Attractive Rate of Return (MARR) 12% per year profitable. Scenario 2 by adding 10 VIP rooms, initially 25 units to 35 units, effectively being able to produce improvements in significantly reducing the waiting list originally from 50.94 hours to 39 minutes there was a decrease (99.23%), and could reduce the utility level or busyness of service in VIP was originally 93.49% to 87.19%. From the results of NPV analysis > 0, and IRR 32.2% assuming MARR 12% per year, constructing 10 VIP rooms in 5 years can give a profit of 20.2% per year. Scenario 2 can be used as the basis for hospitals in making inpatient service system policies, especially in VIP rooms.

Abstract

The stent installation is one of cardiovascular disease treatments which is selected the most to handle patients with blood vessel disease. As the demand for stents increases, more researches are aimed at developing them. This study aims to obtain the optimal link design to produce the best flexibility to the change of stent angle with minimum stress so as not to injure blood vessel plaque. In this study, the stents are polymer stent with different types of links made with PLA materials with strut mirror (S><) design. The study was conducted on two stent configurations, namely crimped and expanded to determine the ability of angular change and maximum stress experienced by both when bending moment applied. The bending moment test was done through simulation based on finite element method in software Abaqus 6.14. The simulation results were then used as a model-making reference to determine the desired optimization design using the help of Minitab 18 software based on the response surface method. The results of this study indicate that the best optimal flexibility on crimped stent L1 to L5, which is the highest flexibility with von mises stress in the safety limit can be obtained based on a combination of link design parameters in the form of bending moment of 0.0074 N.mm with a thickness of 100 μm L3, and 0,0087 N.mm with a thickness of 106 μm L5. While at the expanded stent L1 to L5, the optimal link design parameter value for obtaining the best flexibility with von mises stress within the safety limit is a bending moment of 0.0075 N.mm with a thickness of 63.78 μm L3, 0.0067 N.mm with a thickness of 70 μm L5.

Abstract

This study developed a new product development planning framework for small and medium enterprise (SME) in creative industry sector to increase the business competitiveness. The development process referred to the stages of design science research. The development stage adapted the first two stages of the modular function deployment (MFD), those are the description stage of consumer need through the house of quality, and functional decomposition. The study explained that the application of MFD adaptation is effective and adequate to the creative SME condition. The technical concepts were   able to be screened and scored by using pugh selection matrix. However, every technical concepts could not be described into detailed domain functions and means. Therefore, the addition of methods applied in parallel was carried out, that is the concept decomposition with the function means tree, and the technical solution synthesis with the axiomatic design so that the design process is easier to handle. It’s recommended to eliminate the zigzagging process in axiomatic design, since it has been done on the function means tree and the use of customer relationship management data base to support voice of customer.

Abstract

There are many frauds involving the trade of beef. Traders do the fraud by replacing the beef it sells with pork. Also, the lack of consumer knowledge of the difference between beef and pork make these traders unscrupulous. Because we research by designing and creating systems that can identify and analyze the freshness of beef and pork. This system uses a color sensor as a color identifier in meat and humidity sensors to measure the level of freshness of meat. Also used is also a microcontroller as an acquirer and data processor. This system is designed to distinguish between beef and pork. This study involved data collection on beef and pork as much as 420 data. These data have shown that this system has an accuracy of 79%, 80%, 80%, 83%, 77% and 81% in identifying fresh beef, fresh pork, less fresh beef, less fresh pork, the cow is not fresh, and the pork is not fresh in sequence. This system is portable because it can be taken anywhere with a battery that supplies the power of this tool. With this system, consumers can distinguish between beef and pork and can know the level of freshness in each meat.

Abstract

Synthesis of Fe3O4@SiO2 modified with propyldiethylenetriamine (Fe3O4@SiO2@PDETA) with variation of synthesis routes have been investigated. Research was begun with synthesis of Fe3O4 using dispersion agent of trisodium citrate at coprecipitation system through stirring using ultrasonic wave. Coating magnetite with propyldiethylenetriamine modified silica was carried out through sol-gel process with two different mixing sequences of raw materials (two synthesis routes) with main materials of Fe3O4 synthesized, N-[3-(Trimethoxysilyl)propyl]-diethylenetriamine (TMSPDETA) and Na2SiO3. The products were characterized by fourier transform infrared (FTIR) spectrophotometer and scanning electron microscope-energy dispersive X-ray (SEM-EDX). Results indicate that Fe3O4@SiO2@PDETA has been synthesized succesfully. Fe3O4@SiO2@PDETA synthesized through route 1 (magnetite mixed with a mixture TMSPDETA and Na2SiO3) contains more propyldiethylenetriamine group than that of through route 2 (magnetite mixed with Na2SiO3 solution, then mixed with TMSPDETA)

Abstract

The goal of movement was to improve the service through placing the governmental office area in one integrated location. Furthermore for spatial context it would be highly expected to be the instrument of urban development as well as to trigger the establishment in the expansion area. According to Urban Spatial Detailed Planning (RDTR) of Boyolali Year 2012 – 2032, the new location was the expansion of Boyolali City which included part of Mojosongo Dictrict covering Kemiri Sub-district, Mojosongo Sub-District and Kragilan Village. Those mentioned administrative regions were capable to be developed. This research aimed to identify the movement impact of governmental office area towards the development of Boyolali urban area. The methodologies being used in this study were deductive quantitative with the comparison between the condition of former and current governmental office area. The analysis was conducted with quantitative descriptive method and spatial descriptive. This study proved that the movement of governmental office area gave the impact in developing the urban area. The impact began with the land-use change from agriculture turning into the settlement, trade and service, and industrial areas, also gave the transformation for the accessibility improvement such as the addition of road network and the increment of land price. The result of analysis towards existing land-use in 2018 with land-use zonation according to RDTR Boyolali Urban Area 2012-2032 (map zonation and text) found out that there was deviation in the usage of green open space and industrial area. That issue showed that the urban development should have been included the instrumental implementation in case of controlling the space utilization for liveable city.
