Unslotted Hybrid CDMA/ISMA Protocol for Indoor Wireless Computer Communications
No full textA hybrid Code Division Multiple Access / Inhibit Sense Multiple Access (CDMA/ISMA) protocol has been proposed as an effective multiple access scheme for Indoor Wireless Computer Communications. This new protocol combines the advantages of both CDMA and ISMA into one protocol. On the one hand the ISMA protocol introduces a limitation to the number of simultaneous accesses to the transmission channel. On the other hand the CDMA protocol introduces an improvement to the packet survival chance. It is shown that the performance of the hybrid protocol is indeed better than CDMA only. In addition, code sharing can be applied to reduce hardware cost. The slotted hybrid CDMA/ISMA protocol using the p-persistent ISMA scheme has already been analysed. In this report, we investigate the hybrid protocol using the unslotted non-persistent ISMA scheme. The analysis is done for a star-connected multiple access wireless computer network. The performance comparison between the slotted and unslotted hybrid CDMA/ISMA protocol is evaluated in terms of throughput and delay using computer simulation and mathematical analysis.Electrical Engineering, Mathematics and Computer ScienceTelecommunicatie- en Verkeersbegeleidingssysteme

Performance Analysis of Slotted ISMA Protocols for Mobile Communications on a Three Lane Motorway
No full textA slotted ISMA protocol has been proposed for using with the communication channel from vehicles to a base station near the motorway. In this report the performance of this channel using the proposed protocol is analysed. Three slotted ISMA protocols can be distinguished, namely: • p-persistent slotted ISMA; • 1-persistent slotted ISMA; • non-persistent slotted ISMA. The performance of the protocol has been measured in terms of the throughput and the packet delay of the communication channel. The system has been modelled by assuming a capture receiver at the base station. The vehicles are assumed to maintain constant velocities while moving in one direction inside a cell of 200 metres on a three-lane motorway. The distribution of the vehicle positions on the motorway has been considered. Also the influence of the packet length and collision detection ratio will be examined. Furthermore the integration of DECT with the designed system is investigated. The performance of the system has been investigated for three traffic types: light traffic, heavy traffic and queuing traffic.Applied SciencesElectrical EngineeringTelecommunications and Traffic-Control Systems Grou
Peran Pemerintah Terhadap Tenaga Kerja Indonesia Tahun 2004-2014 (Studi Kasus TKI Asal Jawa Barat ke Saudi Arabia)
No full textABSTRACT Andi Riva Isma. C0513004. Government Role About Migrant Worker Between 2004-2014. Thesis: History Departement, Faculty of Cultural Science, Sebelas Maret University, Surakarta. The issue discussed on this research is about: (1) how the background of migrant worker development in West Java, (2) sociologic condition of West Java society (3) interest of West Java Society who want to go to Saudi Arabia, (4) the government policy about placing and protection of migrant worker in Saudi Arabia. The method on this research covering such as Heuristic which is a collecting of primary and secondary data obtained from BNP2TKI, BP3TKI, and Migrant Care. The next stage of source criticism namely compare and criticize historical sources to obtain data that is valid or invalid. Then, interpretation that is namely exposure and analyze to reduce subjectivity. And the last step is historiography, the writing of history in accordance with the characteristics of the writing of history that has a period, unique and interesting and the writing has the development and change. The result of this research is show us that between 2004-2014, West Java is the most migran worker sender with the highest ammount among other province in Indonesia, it caused by pull and driving factors. The pull factor is caused by; Saudi Arabian is a rich country, very high migrant workers demand for the domestic sector, and high sallary offer. Then, the driving factors covers economic circumstances that encourage to improve the standard of living, an open opportunity even for junior high school graduates, also the ease of pilgrimage when they have succesfully worked in Saudi Arabian. Meanwhile, the development of migrant workers departure who came from West Java to Saudi Arabia between 2004-2014 tend to be variated, and the higest amount is in 2011 which is 58.385 persons deeparture to Saudi Arabia. Also at 2011 the goverment applied migrant workers moratorium to Saudi Arabia as a form of goverment role in minimize case of violence that has happened in a long time. One of the causes of many cases of violence is the absence of direct protection regulations to protect domestic workers in the domestic sector by the Saudi Arabian government. The conclusion of this research is, on February 19th 2014 has reached an agreement about the placement and protection of domestic workers in Saudi Arabia. The success of the MoU signing agreement is the result of the hard work of the government to fight for the protection of Indonesian workers between Indonesia and Saudi Arabia.

Performance Analysis of a Hybrid ISMA/CDMA Protocol for Indoor Wireless Communication
No full textThe hostile transmission medium encountered in Indoor: Wireless Communications (IWC) requires the use of special communication protocols. In this report we investigate a combination of the Inhibit Sense Multiple Access (ISMA) and Code Division Multiple Access (CDMA) protocols. The ISMA protocol limits the number of simultaneous accesses to the transmission channel and the CDMA protocol improves the packet survival chance. With CDMA each bit is transmitted using several code bits, giving each signal has its own, easy to recognize, signature. Coding spreads the signal over a large transmission bandwidth, which makes it particularly resistant to fading and multipath propagation, two key factors which degrade network performance…Applied SciencesElectrical EngineeringTelecommunications and Traffic Control Systems Grou

Sehingga dalam penelitian lanjutan ini, tujuan yang akan dicapai adalah merancang konsep one river one plan dalam penataan DAS Binanga Lumbua secara komperehensif untuk mewujudkan pembangunan yang berkelanjutan. Analisis yang digunakan adalah berupa analisis spasial dan deskriptif kualitatif.Hasil penelitian ini berupa pemetaan konsep penataan DAS yang berbentuk site plan. The criticality of the Binanga Lumbua watershed is that it contributes to the decline in the income per capita of Jeneponto Regency. This is also one of the reasons why Jeneponto Regency is the only area in South Sulawesi Province that is included in the category of underdeveloped areas. Looking at the physical condition of this area which has a varied topography and fertile soil, this area should have potential economic value for the development of forestry, plantation crops, and food crop agriculture. The results of previous research were the identification of drought using a hydrological approach both qualitatively and quantitatively. Then, provide directions for spatial use based on drought prevention efforts. So that in this follow-up research, the goal to be achieved is to design a 'one river one plan concept' in the comprehensive arrangement of the Binanga Lumbua watershed to realize sustainable development. The analysis used is in the form of qualitative descriptive and spatial analysis. The result of this research is a mapping of the watershed planning concept in the form of a site pla
