Abstract

Multitasking is one of the most challenging issues in the automation industry which is highly depended on the embedded system. There are two methods to perform multitasking in embedded system: RTOS and primitive interrupt. The main purpose of this research is to compare the performance of R¬TOS with primitive method while concurrently undertaking multiple tasks. The system, which is able to perform various tasks, has been built to evaluate the performance of both methods. There are four tasks introduced in the system: servo task, sensor task, LED task, and LCD task. The performance of each method is indicated by the success rate of the sensor task detection. Sensor task detection will be compared with the true value which is calculated and measured manually during observation time. Observation time was varied after several iterations and the data of the iteration are recorded for both RTOS and primitive interrupt methods. The results of the conducted experiments have shown that, RTOS is more accurate than interrupt method. However, the data variance of the primitive interrupt method is narrower than RTOS. Therefore, to choose a better method, an optimization is needed to be done and each product has its own standard.

Abstract

Saat ini sertifikasi di dunia konstruksi sangatlah diperlukan oleh para Project Manager khususnya yang bekerja di bidang konsruksi. Hal ini dikarenakan dengan mengikuti sertifikasi yang tepat akan sangat membantu bagi kemajuan karir Project Manager tersebut. Penelitian yang dilakukan pada tugas akhir ini bertujuan untuk mengetahui seberapa banyak manfaat yang akan didapatkan oleh Project Manager dengan mengikuti sertifikasi di dunia konstruksi. Metodologi yang dipergunakan adalah pengumpulan data survei dari internet dan analisa data survei. Berdasarkan hasil dari studi literatur tentang berbagai macam sertifikasi tersebut, dipilih 5 asosiasi sertifikasi untuk dibandingkan. Adapun ke-5 asosiasi tersebut adalah IPMA, PMI, PRINCE2, IAMPI dan ASTTI. Asosiasi sertifikasi IPMA, PRINCE2 dan PMI merupakan asosiasi sertifikasi yang paling banyak diikuti oleh Project Manager dibanding dengan asosiasi sertifikasi IAMPI dan ASTTI. Hal ini dikarenakan asosiasi sertifikasi IPMA, PRINCE2 dan PMI merupakan asosiasi sertifikasi yang berskala internasional dan memiliki daerah jangkauan serta pengaruh dan manfaat secara global

Abstract

Abstract Congestion is one of the severe problems that occurs in big cities like Jakarta, the center of the Indonesian government. One alternative solution to solve this problem is with a Traffic Information System which is easily accessible by the public. Twitter as a social media can be used as one of information source to develop the Traffic Information System. The most common problem in the processing of information on Twitter, especially in Indonesia, is the use of abbreviations and typographical error (typo). We propose an application of Web Place Name Dictionary in addressing abbreviations and typos in the name of the location contained on Twitter to develop a Traffic Information System. Three cases in find coordinate point in the street that derived from location name in Twitter can be handled through the proposed system. This system produces 90% accuration rate on 100 data set that obtained via @TMCPoldaMetro. This study only focus on the implementation of Web Place Name Dictionary method so we do not compare our system with the other methods.

Abstract

Sistem Informasi Zakat (SIZakat) is a web-based information system that is used to assist in the management of zakat in Imam Bonjol Mosque Pondok Labu, South Jakarta. In this thesis, we conducted testing to the SIZakat application to know the quality and the feasibility. We conducted seven kinds of testing: Unit Testing, Integration Testing, Stress Testing, Load Testing, Testing SQL Injection, XSS Injection Testing and User Acceptance Testing. In addition to ensure the quality of SIZakat, the SIZakat test result is expected to be a reference for future quality improvement. Test results show that SIZakat have accurate functionalities, good security, and good performance.

Abstract

Abstract In general, Zakat Information Systems is established to manage the zakat services, so that the data can be well documented. This study proposes the existence of a feature that will determine the amount of zakat received by Mustahik automatically using C4.5 Decision Tree algorithm. This feature is expected to make the process of determining the amount of zakat be done easy and optimal. The data used in this study are the data taken from Masjid An-Nur, Pancoran, South Jakarta. The experiment results show that the proposed feature produces an accuracy rate over 85%.

Abstract

Sistem Informasi Database Riset dan Pengmas (SIDR) is an information system that saves the reseach and community service data in Universitas Indonesia. To evaluate the effectiveness of SIDR, it is ideal to gather data about the SIDR user’s responses. Consequently, in the present study, questionnaire method uses a 6-point Likert scale is applied to obtain that kind of information. In general, the results show that SIDR provides an effective means of creating and centralizing research and community service data for whole faculties in Universitas Indonesia.

Abstract

On the contribution to scientific publications, The Faculty of Computer Science Universitas Indonesia (Fasilkom UI) holds an annual international conference entitled International Conference on Advance Computer Science and Information Systems (ICACSIS). This international conference is aimed to be a platform for scientists all over the world to present their findings to other colleagues of the same interest. The process of collecting papers from these particular countries is not easy. Thus, a system that can automatically manage the paper submission process is needed. There are numerous webbased conference management systems on the Internet. Despite the basic common features, many of them offer various features that distinguish them from the others. This paper presents various features that are available in the market, analyzes the functions of features that meets the ICACSIS paper management’s requirement and integrating both the former and the later.

Abstract

Sorting is common process in computational world. Its utilization are on many fields from research to industry. There are many sorting algorithm in nowadays. One of the simplest yet powerful is bubble sort. In this study, bubble sort is implemented on FPGA. The implementation was taken on serial and parallel approach. Serial and parallel bubble sort then compared by means of its memory, execution time, and utility which comprises slices and LUTs. The experiments show that serial bubble sort required smaller memory as well as utility compared to parallel bubble sort. Meanwhile, parallel bubble sort performed faster than serial bubble sort

Abstract

Register is one of the computer components that have a key role in computer organisation. Every computer contains millions of registers that are manifested by flip-flop. This research focuses on the investigation of flip-flop performance based on its type (D, T, S-R, and J-K) and architecture (structural, behavioural, and hybrid). Each type of flip-flop on each architecture would be tested in different bit of shift register with parallel load applications. The experiment criteria that will be assessed are power consumption, resources required, memory required, latency, and efficiency. Based on the experiment, it could be shown that D flip-flop and hybrid architecture showed the best performance in required memory, latency, power consumption, and efficiency. In addition, the experiment results showed that the greater the register number, the less efficient the system would be.
