The Comparison of Bundle-Pricing Scheme Models Using Quasi-Linear Utility Function Fitri Maya Puspita; Evi Yuliza; Muthia Ulfa
INSIST Vol 1, No 1 (2016)
Publisher : Universitas Lampung

Abstract—— In this paper, we formulate bundle-pricing modified models involving pricing scheme based on quasi-linear utility function as one of internet service provider (ISP) main goal is to maximize their profit. The model formed by setting cost of creating bundle and total reservation price of customer i’s. LINGO 11.0 is used to solve the models to obtain the optimal solution. The solver result for each case either from original model and modified model are compared to obtain the optimal solution. The result showed that for each case based on 3-pricing schemes which are flat fee, usage based and two-part tariff, ISPs gain the same profit with the original model but ISPs save more time in terms of resources rather than the original model. ISP’s may use this model as consideration for setting cost of creating a bundle and total reservation price of customer in maximizing profits and also to provide better service quality for customers with their preferences exactly.Keywords— bundle pricing, utility function, pricing strategies, optimal solution.

INSIST Vol 2, No 1 (2017)
Publisher : Universitas Lampung

Abstract—The aim of this study is to elaborate the conserving Kali Pasir Jami’ Mosque in Tangerang City, Banten Province that includes the participation of local communities. There is an initial conservation program proposed by the local government but it is not yet clear of how should the collaboration between communities who have done practical conservation and local government who slowly plans the conservation program. The lack of historical documentation of the building and unstructured research done by communities imply a potential threat to the conservation effort and loss of historical values of the mosque. This paper is the result of both qualitative and quantitative approaches such as observation and in-depth interviews in analyzing the conservation of the mosque. The finding of the research shows the important role of local communities in the sustainability of the mosque although there is also an urge to involve experts and government to create the right strategy in conserving the mosque.Keywords—conservation, Kali Pasir Jami’ Mosque, preservation

Publisher : Universitas Lampung

Abstract— The primary objective of this research were to produce and evaluate the official Indonesian language version of the Rheumatoid Arthritis Quality of Life instrument (RAQoL). The UK RAQoL was translated into Indonesian by a forward-backward translation. A separate lay panel was conducted to consider the appropriateness and comprehensibility of the items in Indonesian. The translated version of the RAQoL was pilot tested to determine whether the questionnaire RAQoL could be well understood and well accepted. Pilot test was conducted by interviews with 20 subjects, which 10 healthy Indonesia people and 10 rheumatoid arthritis patients who were recruited from X hospital in Yogyakarta, Indonesia. Items on the two response format questionnaire used in pilot study were scored one for a ‘yes’ response and zero for a ‘no’ response. The individual total item scores with a high score indicating poor QoL. Few difficulties arose in the translation process and the new language version was well received by the lay panel and field-test participants. Statistical analysis was conducted to determine the difference of completion time between healthy subjects and RA patients, and the total score of the questionnaire answers between healthy subjects and patients. The average total score of responses to questionnaire on the healthy subject and patients by T test was significantly different (p < 0.05). The official Indonesian RAQoL was well received by RA patients. The psychometric quality of the translated questionnaire means that it is suitable for validity and reliability of the questionnaire towards patients with RA.Keywords—Rheumatoid Arthritis, questionnaire, RAQoL, translation, pilot test

Abstract— This Previous research suggests that magnetic field (MF) can enhance seedling vigor, growth, and the production of tomato plants. This study examines the influence of MF on the growth of tomato infected by Fusarium oxysporum, fungal pathogen that causes Fusarium wilt in tomatoes. This factorial study arranged in a stripe split plot design. Factors tested consists of long exposure to the MF, M (control; 7'48 "; II'42" and 15'36 "), how to infect fusarium, F (through soaking the seeds and by infecting fusarium through the stem at the age 28 days after sowing (das), and soaking the seeds, S (soaking and without soaking for 15 minutes before MF treatment). Each unit of experiment was repeated 3 times. Parameters measured were percentage of germination, growth rate based on plant height, and fresh weight. Observations were made on the plant until 42 das. Data were analyzed of variance followed by the least significant difference (LSD) test at α = 1 and 5%. The results showed that the interaction between MF and fusarium (MxF), fusarium and soaking (FxS), and MF, fusarium, and soaking (MxFxS) did not produce a different response on all parameters measured. Differences in response to the treatments derived from the treatment of MF (M), Fusarium (F), and the treatment interaction of the MF x soaking (MxS). The MF (M) and the interaction of MF and soaking (MxS) significantly effect on all parameters measured at each measurement. The treatment of Fusarium (F) significantly effect on germination percentage, and fresh weight at 7 das.Keywords— magnetic field, fusarium, germination percentage, growth rate, fresh weight.

Publisher : Universitas Lampung

Abstract— Fuzzy Decision Making involves a process of selecting one or more alternatives or solutions from a finite set of alternatives which suits a set of constraints. In the rule-based expert system, the terms following in the decision making is using knowledge based and the IF Statements of the rule are called the premises, while the THEN part of the rule is called conclusion. Membership function and knowledge based determines the performance of fuzzy rule based expert system. Membership function determines the performance of fuzzy logic as it relates to represent fuzzy set in a computer. Knowledge Based in the other side relates to capturing human cognitive and judgemental processes, such as thinking and reasoning. In this paper, we have proposed a method by using Max-Min Composition combined with Genetic Algorithm for determining membership function of Fuzzy Logic and Schema Mapping Translation for the rules assignment.Keywords— Fuzzy Decision Making, Rule-Based Expert System, Membership Function, Knowledge Based, Max-Min Composition, Schema Mapping Translation

Library Automation Systems Integration (Case: ELIB and SLiMS) Meizano Ardhi Muhammad; Mardiana Mardiana
INSIST Vol 1, No 1 (2016)
Publisher : Universitas Lampung

Abstract—The Library automation system help reduce much work need to be done by doing monotonous routine jobs with the help of technologies such as Barcode and RFID. Unila Library as the pioneer of RFID technology implementation in Lampung province face challenge in migration. Unila Library used SLiMS Library Automation System to manage collections, which use mainly barcode to identify collection. RFID uses allow collections to be scanned in gate and warn librarian. Unfortunately, SLiMS doesn't support SIP2 protocol which is needed by RFID devices (gate, kiosk) to function properly. Therefore, a solution must be made to address the migration of data and support SIP2 protocol. ELIB is a library automation software which support SIP2 protocol. So, library automation systems integration which synchronize both database in ELIB and SLiMS to keep up to date data and allow support for SIP2 protocol must be made in the form of middleware. Some of difficulties arise in integration was the development of both library automation systems which require fine tuning everytime update occurs and both systems in active use. Benchmarking is done to find anomaly and disreparancies of data. And, because the integration system is build as middleware, it remain flexible and open to future development. It can be concluded, Library automation systems integration require vigilance and keen observations into minuscule level especially because both systems are so different.Keywords— library, RFID, ELIB, SLIMS, SIP2, middleware

This paper discusses the development of a numerical simulation platform that can be used for representing the principal works of aircraft systems. The platform consists of some parts each of which is intended to replicate the operation of a system implemented in a modern aircraft, such as hydraulic line, electrical system, landing gear system, control system, etc. The platform is intended to be a tool for modeling and analyzing the operation and performance of certain systems configuration. To some extend the platform can be viewed as a virtual Iron Bird System. Iron Bird is a term representing a platform for simulating the works of aircraft systems using real components, which is very important for aircraft system development. At this stage, the numerical platform will only involve some sub-systems, namely main hydraulic line, control surface actuation, landing gear, and control system. These sub-systems are chosen to be the basis for further development where other sub-systems will be added and integrated to the platform.Keywords—Aircraft System, Numerical Simulation, System Analysis

Abstract—Changes in land use have occurred quite significant in the city of Pekanbaru. The increasing of building spaces, the decreasing of plantations and forests are continues to grow with the increasing of population and industries. This means, it can cause impact on groundwater resources. This condition shall continue in effect, along with the population and industrial growth. This means, it can cause impact on groundwater resources of Pekanbaru City, thus the analysis of groundwater zone of Pekanbaru city is needed. The data used in this research is related with the biophysical and social economic. Data analysis method was using numeric simulation programming using finite difference method. The results showed that in 2016, its depth ranges between 16-46 m, this indicates that the unconfined aquifer was in trapped position but not included to the confined aquifer system. In 2017, it was predicted that the depth is about 6-38 m, and in 2018 the depth of unconfined aquifer will go deeper to 31,4-34 m. This is influenced by the changes of population and industrial and the automation of extraction of groundwater by those population and industrial is getting bigger. While in 2019 and 2020, the depth of the unconfined aquifer will be between 41,8-44,4 m and 44-46,8 m. It was predicted that the growth of population and industries will grow rapidly in the future. This rapid growth will cause the damage of the aquifer. Keywords—Zone, groundwater, numerical method.
