Abstract

The Status of Legal Entity State Higher Education (PTN-BH) at the Institut Teknologi Sepuluh Nopember (ITS) gives full autonomy to the management of higher education. For ITS to be able to innovate in exploring revenue generators, Business Development and Management Agency (BPPU) was formed which functions to raise, manage funds, and develop business units. Professional cooperation as one of the most dominant ITS business unit in contributing ITS revenue. BPPU as the administrative center for professional cooperation services always try to provide excellent service, but there are still complaints about these services related to speed and accuracy. To analyze the level of quality of professional cooperation services, this research uses the Servqual, Importance-Performance Analysis (IPA) and Quality Function Deployment (QFD) methods. Servqual is used to analyze the gap between perception and customer expectations. The IPA method is used to measure the performance satisfaction expected and received by customers. And the QFD method is used to design priority strategies for improving service quality according to customer desires and technical capabilities by internal managers of professional cooperation. Servqual analysis results show the greatest gap between the perception variable and customer expectations, namely Em1 (understanding specific needs), Em2 (clarity of procedure), Rs2 (responsive service capability), and As3 (accuracy of cooperation services management). The results of the IPA analysis show that the variables in the quadrant A are the same as the results of Servqual Analysis which also have high priority to be handled, namely Em1, Em2, Rs2, and As3. In QFD analysis, these variables become customer requirements (whats) associated with technical responses (hows) obtained from internal BPPU management, and according to the house of quality diagram, the priority sequence of technical response is obtained, the priority of the technical response can be applied internally by BPPU so that FGDs are carried out, with the hope that a strategy for improving service quality can reduce complaints from professional cooperation customers.

Abstract

Modeling and simulation using computer software are very important in supporting various types of research based on data calculations. In the research process, accuracy is needed between the simulation results and the results of field measurements. Thus, there is no significant difference between the two results. This study aims to verify and validate the result of field measurements and simulation using the ARCHIPAK 5.1 software. The variables studied focus on indoor air temperature and humidity. This research takes a case study in the village of Ranupane which is located within the Bromo Tengger Semeru National Park. There are 4 housing buildings measured which consist of two types of houses using fireplaces and two types of houses without fireplaces. All of the four houses are afterward modeled using the ARCHIPAK 5.1 software to validate the data results. From the measurement results, the field measurement data show a higher hourly temperature profile compared to the results of the simulation of the base case model. Two striking differences are the type of house without a fireplace which is showing the difference in the average temperature of 1-2 K. While the type of house using fireplace shows the difference average temperature of 5,2-5,3 K. This occurs due to the internal heat gain input which the value is a slight difference between the result of field measurements and simulation of the base case model. This data verification and validation will be used as modeling optimal building configuration for housing in a humid tropical highland climate.

Abstract

Banjarmasin city has the character of settlements along the river that reflects the concept of the authentic Banjar settlements on river banks as a product of Nusantara architecture’s. However, the existence of these settlements began to lose their existence due to changes in life orientation from river culture to landed culture. To restore the existence of these settlements, the government of Banjarmasin city plans to develop these settlements into tourist villages with Banjar culture. This encourages optimization of existing potential by improving the quality of settlements that pay attention to various aspects in the context of the location being developed, such as environmental damage, water quality, and applicable regulations. Although there are many design criteria related to riverbank settlements in Banjarmasin, there are some aspects that have been neglected such as the cultural aspects of urang Banjar which are related to the river and Islam. This has an impact on the quality of settlements that reduce the level of kinship in the Banjar community. By using a force-based framework, the design criteria will be formulated by applying a strategy of extending tradition. The design criteria produced, cover various design aspects that are closely related to activities, order, form, building construction, supporting elements, and circulation patterns to improve the quality of the settlement, so that it can develop into a self-sustaining area with food security, energy sources, and the conservation area of Banjar culture.

Abstract

Inspection companies supporting upstream oil and gas business activities with multi-owned businesses are demanded to compete and survive in increasingly fierce market competition. Differences in the characteristics and scope of each business unit makes the company encouraged to be more observant in seeing the position rate of development of each business unit. A strategy is needed to ensure the treatment of each of these business units in order to achieve company goals. Identification, clustering and analysis of influencing factors affecting the company business performance are carried out through the stages of collecting secondary and primary data to obtain a follow-up plan for each business unit of the company. We use the real case in one of Indonesian Inspection Company. The method used in this paper is the analysis of strategy formulation in determining business strategies by three stages. First stage IFE (Internal Factors Evaluation) matrix and EFE (External Factor Evaluation) matrix are prepared then follow by IE (Internal External Matrix). Second stage, by assesment the following matrixes, we matched up with SWOT (Strength, Weakness, Opportunity, and Threat) matrix. Finally the final stage is taken by using QSPM (Quantitative Strategic Planning Matrix) to determine reliable strategy for inspection company in the upstream oil and gas business activities.

Abstract

A proper maintenance project selection is a key to support performance of power plant. The issue of maintenance is allocation a limited budget to achieve the goals of various maintenance criteria and conflicting objectives. This paper presents an integrated AHP and goal programming. In the first step, since maintenance is measured in qualitative criteria, it is recommended to use AHP to weight and quantify criteria. Second step utilize GP which uses the criteria weights and alternative priorities calculated with AHP to optimize multiple objectives without exceeding available resource constraint. The results show that the approach can aid in selection optimal projects within available budget.

Abstract

Since 1975, the drinking habits of the Indonesian people began to change from being merely boiling water from tap to bottled water (AMDK), thus encourage drinking water producers to continue branch out in market share. In 2013, the market share of AMDK industry was Rp 22.51T and there were around 500 competing AMDK companies. PT. Distribusi Air Santri (PT. DAS) is a company engaged in the distribution of “Air Mineral Santri” brand which located in Surabaya. This company aims to increase the market in Surabaya by 10% or sell 142,000 items / month. So to achive company goals, company need to develop business models and plan business strategies using Business Model Canvas (BMC). In the BMC analysis, an analysis of environmental conditions was carried out using the 7sMcKinsey method, External Scanning and porter strength analysis. And validation is needed so that BMCs are made accurately and precisely with the help of a SWOT analysis.

Abstract

The bolt as an element which integrates several small parts to a united big structure had been used since a long time ago. This type of impermanent joint holds many advantages in the engineering field such as facilitating the maintenance, particularly at the change of defected part, and also making the delivery of many parts composing a huge structure more sensible by transporting them in diverse modes of transport. One of problems using this type of joint is sometimes it is difficult to assure holes position between parts to be aligned just as designed, in order to facilitate positioning of parts during assembly we could possibly use parts with slotted hole. However, a slotted hole will result in a reduced contact surface between the bolt and parts assembled, therefore the behavior of this type will be clearly different compared to the assembly with normal hole. The research will be conducted with assistance of a finite elements software ABAQUS® for simulating the model along with its parameters and mathematical software Matlab® for interpolating data obtained from the simulation. Firstly, the model will be validated by comparing it to experimental result of research conducted by Bakhiet[1], then its boundary conditions and mesh will be used to next model simulations. Secondly, the parameters of the assembly will be varied such as bolt positions on the part and the modulus Young ratio of bolt and parts. Finally, both assemblies are to be compared (e.g. with normal and slotted hole) and then the assembly’s critical value is to be found by using dimensionless parameters developed by Turgeon and Vadean[2]. From research conducted, we could conclude that the behavior of the assembly, particularly at its fatigue stress produced at the bolt, changes significantly with the variation of the bolt position and also the modulus Young ratio of the bolt and part. A reduced value of fatigue stress produced will be achieved while the bolt position is the nearest possible with respect to the point where load applied. Whereas, a higher modulus Young ratio will convict a higher fatigue stress produced at the bolt

Abstract

An unmanned high-speed vehicle requires a high resolution control unit to decide whether the vehicle should break or steer. This paper describes the utilization of a Frequency Modulated Continous Wave (FMCW) radar to detect the distance and angular position of the target relative to the moving vehicle. These informations are calculated from some numbers of data obtained from a radar system that is mounted on the moving vehicle. To obtain a high angular resolution, a phase-processing approach is introduced by extracting the constant phase information from the radar FMCW beat signal. It is found that a very high angular resolution can be obtained by processing the phase information, independent from the change of relative velocity between the radar and the target. However, this method requires a very stable radar system with high phase resolution and accuracy.

Abstract

Myanmar has a great strike-slip active fault called the “Sagaing Fault Zone” besides the Sumatra-Andaman Subduction Zone. Major cities (Yangon, Naypyitaw, Bago and Mandalay) are at risk along this fault. Recently, in 2012, Thabeikkyin earthquake with Magnitude of 6.8 caused collapse of many residential housings and ground failures near Mandalay. Therefore more attention should be paid for Yangon which has no large earthquakes since 1930 and is the largest not only in population but also in socio-economic activity. One of the most important concerns after an earthquake is to survive under any disastrous conditions. The medical care is requested not only for emergent injured people after an earthquake, but also for various types of patient and aged people from several weeks to longer periods. So medical center must be always functional before and after earthquake. For this purpose, medical buildings should be structurally resilient and also be functional for medical services by sustainable supply of electric power, water and any other delivery service which can be carried out by urban lifeline systems. This research is to investigate the structural vulnerability of hospital buildings and facilities, to assess the performance of urban lifeline systems and to check the operational capability of medical services in which surgical capability and life safety management method should be discussed. The water supply system is adopted as a typical lifeline system in Yangon in this study. One sample medical center in Yangon is adopted to carry out this analysis. Finally, the performance of medical services after the earthquakes can be assessed in a probabilistic manner.
