Abstract

Four shaped models of delivery valve had been investigated and compared to improve performance of a hydraulic ram. Hydraulic ram pumps have been constructed and operated. Most of them built locally using steel pipe fittings that commercially accessible in the market rather than factory-made one. These have assisted inhabitants in rural or hilly area where water sources available for water supply services or irrigations. However, the major problem challenged by the public was on designing and repairing of the impulse and delivery valves of the pumps. Performance of the pumps are affected predominantly by the both valves. One characteristic of the valves is their shape. Considered on the characteristics of the fluid flow through surface of plate and sphere object are different on the pattern and losses. Therefore, investigation is necessitated to find a proper shape of the delivery valve for enhancing the performance of the pump. In this research four valve models were experimented to assess the hydraulic ram pump performance on varies delivery heads. The results show that the sphere model of the delivery valve offered the best efficiency, then followed by the membrane, the half-sphere and the flat delivery valve models. However, the rounded model: sphere and half-sphere delivery valve model were facing obstructions in implementation for a high delivery head.

Abstract

Concerns about the waning identity of Balinese architecture led the Provincial Government of Bali to issue Perda No. 2, 3, 4 of 1974, which was later revised to No. 5 of 2005 concerning Architectural Requirements of the Building. . This requirement emphasizes that building architecture in Bali must have the characteristics of Balinese traditional architecture, especially in tourism areas where there are many tourist accommodations. But on the other hand, there are various perceptions and interpretations according to the interests of each architect regarding the Architectural Requirements of the Building. Architects as practitioners in architectural design have a responsibility to maintain environmental quality, especially architecture in Bali. This study aims to identify the Architectural Requirements from an architect's point of view. The subject is architects who practice in Bali, selected by purposive sampling technique with the keyword tourist accommodation architectural designers in Bali. The variables of the design process that are the focus of the study are aspects of creativity dan critical issues. This study uses a qualitative descriptive analysis method, namely by using a questionnaire with a Likert scale. Data analysis was performed by ranking each statement variable to obtain a comparison between the architect's interpretation variables. This study identifies two broad categories, namely how architects view traditional Balinese architecture as a priority issue that must be considered in designing and how the architect's cognitive response to Architectural Requirements in the design process.

Abstract

The use of composite materials for panel boards, building construction, vehicle accessories, and household furniture is growing. Coconut coir fiber-reinforced composites can be applied as panel boards for building and furniture construction, which can also be used as heat storage systems. The coco fiber composite's low energy storage capacity can be increased by incorporating PCM material into it, forming a PCM composite material. Heat absorption and release performance depend on the material's thermal conductivity, which can be increased by adding additives such as graphite. This paper presents a performance test of PCM composites to obtain bending strength and thermal conductivity. The research materials were coconut coir fiber, polyester, paraffin, and graphite. The weight fractions of coco fiber and polyester were 30 and 50%, respectively. Variation of paraffin weight fraction 15 and 20% and variation of graphite weight 0 and 5%. The method of mixing materials is direct incorporation and forming of PCM composites using a press molding process. The tests carried out include the bending test (ASTM D790-03) and the thermal conductivity test using the Heat Transfer Experiment Base Unit test kit. The results show that the use of 15 wt% paraffin with 5 wt% graphite increases thermal conductivity by 23.27% and increases bending strength by 36.71%.

Abstract

Abstract. The development of a city cannot be separated from how its people view a city. People who understand how the culture of the city will give a strong identity and character to the city. Over time, there are differences in how people perceive elements of the city, one of which is the catuspatha. Catuspatha is no longer interpreted as empty space but began to get additional functions as aesthetic and elemental elements of city landmarks (landmarks). There are several meanings arising from the physical aspects and socio-cultural aspects of a catuspatha as a landmark of the City of Semarapura. This research focuses on Catuspatha Semarapura City in terms of physical and socio-cultural aspects. The data search was carried out by means of litelature studies, field observations and interviews with people who were active in and around Semarapura City. By using a qualitative descriptive method, this research results that the Semarapura catuspatha in terms of physical size has different criteria with its environment so that it is physically prominent, unique, easy to remember, easily recognizable, has historical and aesthetic value. From the socio-cultural aspects of the area around the Semarapura catuspatha also functions as a node, in which at this location a variety of activities are held mainly related to social and cultural activities such as Tawur Kesanga, Ngulapin, Nebusin, Ngelawang, and other activities including Ogoh-ogoh parade activities, various festivals and folk parties and also cultural marches. Keyword: catuspatha, identity, landmarks, physical, social culture.

Abstract

The development of technology when making an explosion of the number of news or news documents that are very much on the internet, it is necessary to have clustering done in dividing these documents so that they can be adjusted based on the category of the online news. Application of document clustering can increase the effectiveness of information retrieval by referring to a hypothesis that relevant documents will tend to be in the same cluster if a collection of documents has been clustered. This research aims to try to do clustering on online news about Covid-19 taken from three online news websites contained in XML files. K-Means clustering is used as a grouping of online news by using an open-source application, Carrot2 Workbench which turns out to be able to generate nine clusters of "Covid-19" queries entered in the Carrot2 application.

Abstract

Non player character is an important part of a game that can make gameplay more interesting and challenging. That reason also makes it important to study, especially for non player characters that are clustered in large numbers where programming of such non player characters is relatively difficult to do. Quite a lot of games with non player characters in the form of birds that are clustered but on average the game does not apply good movement so that the motion of birds is relatively slow, monotonous and unrealistic. In this research, we will try to modify the Flocking Algorithm, as one of the popular algorithms for non player character groups, so that birds can fly scattered in terrain while maintaining flocking. In its implementation, the new algorithm was successfully designed and inserted in flocking, which was then applied to a 3D game. The test results are quite satisfactory with only 6.6% collisions on 100 agents with a maximum frame rate of 10 fps. Non player characters succeeded well toward 3 targets in less than 2 minutes and the results of beta testing were an average of 81% of respondents "VERY AGREE" The implementation of the Flocking Algorithm and its modification worked well and resulted in a realistic movement of non player characters.

Abstract

The development of information technology that has developed in government is very helpful in the process of managing government infrastructure. In the Gianyar Regency Development Section which has implemented a system, namely the TEPRA. TEPRA is a system used to carry out the process of monitoring the realization of the budget given to each OPD (Organisasi Perangkat Daerah) in Gianyar Regency to find out any problems or obstacles that might occur when realizing the program of each related OPD. The frequent mistakes made by TEPRA Operators in completing data information about the program of the relevant OPDs are the reason that it is necessary to carry out an audit of the TEPRA information system. The audit process of the TEPRA information system uses a framework, namely COBIT 4.1. In the research process carried out using COBIT 4.1 and with a total of 110 respondents consisting of the Head of the Bagian Pembangunan, the Head of the Sub-Division of Pengendalian and Pembangunan , TEPRA Staff, and TEPRA Operators in each related OPD, resulting in a maturity level of 3.09 (defined). From the results obtained, generally the TEPRA system has been running or implemented properly. With this maturity level, there is a maturity gap so that improvements need to be made in order to achieve the expected maturity level.
