Evaluasi Beban Torsi dan Drag pada Sumur Berarah Mila di Lapangan Lepas Pantai Laut Jawa Bagian Barat dengan Menggunakan Software Dswe

Pemboran berarah adalah sebuah teknologi pemboran dengan membelokkan lubang bor menuju kearah tertentu untuk mencapai target dibawah permukaan bumi yang telah ditentukan sebelumnya. Dalam pemboran berarah, timbulnya beban torsi dan drag yang ditanggung oleh rangkaian pipa bor merupakan salah satu faktor yang mempengaruhi keberhasilan pemboran. Tersebut Sumur Mila adalah salah satu sumur pengembangan gas yang terletak pada Cekungan Sunda yang berjarak kira-kira 50 mil arah Barat Laut dari Jakarta. Dalam kegiatan operasi pemboran pada sumur tersebut, dijumpai adanya peningkatan torsi yang tinggi dibeberapa titik pada saat kegiatan operasi pemboran sedang berlangsung. Salah satu penyebabnya adalah karena kondisi lubang bor yang tidak begitu baik, yaitu karena banyaknya cutting yang ditemukan pada lubang bor. Pada penelitian ini akan ditinjau faktor – faktor yang menyebabkan meningkatnya torsi dan drag pada proses pemboran sumur tersebut . Dan diharapkan dari hasil penelitian ini akan dapat diperoleh suatu cara penanggulangan yang tepat untuk mencegah terjadinya masalah yang mengakibatkan munculnya torsi dan drag yang tinggi

Determination of Irrigation Performance Indices for Paddy Cultivation

Evaluation and monitoring of paddy irrigation schemes (field plot level) traditionally use conventional indices, namely, Relative Water Supply (RWS) and Water Use Efficiency (WUE). Where continuous irrigation was practice, low WUE and high RWS were obtained giving the impression that little water management had been carried out. This is partly blamed on the incorrect use of these indices because the aim of the agency is different from those for which RWS and WUE were developed. A study at field plot level was conducted in Bagan Serai, Perak for one main season to measure the components of water balance in an irrigated paddy field. The components of the water balance were individually measured using a range of equipment. Observations were made to find indicators that can show the performance of water management according to the aim of the agency. These indicators were incorporated in the proposed indices. Plot Consumption Index (PCI) and Effective Water Use Index (EWUI) were developed and proposed to evaluate and monitor the irrigation performance at field plot level. These indices were developed in line with the aim of the agency and that was to maintain the 'Design Water Depth' (DWD) in the field. DWD is the depth of water that should be maintain throughout the planting season. Results of the components of the water balance were used to calculate WUE, RWS, PCI and EWUI. For most of the season, daily values of EWUI were less than 1 but more than 0, indicating that excess water was supplied. Some days recorded negatives values ranging from -0.1 to -6.9. On these days there was heavy rains and the field was flooded. On the weekly basis, week two had a value of 0.32 while week six had a value of 0.16, while the weekly basis, week tw had a value of 0.32 while week six had a value of 0.16, while the last week recorded 2.71 , indicating under supply, a situation commensurate with the end of season. All other weeks indicated excess or flood conditions by its negative values

INFORMATION THROUGH THE FLIPBOOK TO THE LEVEL OF KNOWLEDGE ABOUT DOMESTIC VIOLENCE IN FERTILE COUPLES IN SLEMAN IN 2017

Domestic violence can have an impact on reproductive health. This study aims to determine the Influence of information through the Flipbook to the level of knowledge about Domestic Violence in fertile couples in Sleman in 2017 ". This research is quasi-experimental research. The population is a fertile-age couple in Sleman in 2017. The sample is obtained by simple random sampling. The sample size was 70 respondents for the experimental group and 70 for the control group. The independent variables are the giving of information through flipbook about domestic violence (KDRT). The dependent variable is Knowledge of Domestic Violence. In the experimental group were given information through the Flipbook on domestic violence, while the control group was given leaflets. Instruments in the form of questionnaires and data collection format. Analysis with T Test analysis with significant level 5% (p = 0,05). The results of this research is in the experimental group given information with the average flipbook knowledge level of pretest domestic violence 62.8, standard deviation 7.2 post test average 78.5 standard deviation 6.6. In the control group with leaflet, pretest average of 60.8, standard deviation of 8.9; average post test 71.5 standard deviation 10.4. Average knowledge increase 15.6, standard deviation 8.5, in leaflet group 10.7, standard deviation 10.4 with p-value 0.003. There is a significant difference in the average increase in knowledge of domestic violence between flipbook and leaflet groups. The conclusion of this study is significant of giving the flipbook to the level of knowledge about domestic violence. Keywords : Information, Flipbook, Knowledge, Fertile Couple

Connectivity analysis for mmWave V2V networks : exploring critical distance and beam misalignment

In this paper, we investigate the analytical connectivity performance of Vehicle-to-Vehicle communications when using millimeter wave carrier frequencies, by taking into account its challenges of high path loss and beam misalignment. The connectivity analysis is carried out in two dimensions; first, an analytical and parametric critical transmission range is developed, based on system parameters such as vehicle density and Signal-to-Interference-Plus-Noise ratio threshold, and second, the beam misalignment probability caused by the in-lane lateral displacement of vehicles is determined. The analysis is carried out for antennas with half power beamwidths of 3◦, 6◦, 10◦, 20◦ and 45◦, resulting in different beamwidth regimes depending upon road curvature and vehicle density. For low/medium vehicle density on low-curvature roads, the sensitivity of the network connectivity to the beamwidth is relatively small. On the other hand, the narrowest beamwidth is the best performer in terms of maximizing connectivity in low/medium vehicle density scenarios on high-curvature roads, and the wider beamwidth is the best performer for high vehicle density on low-curvature roads

Worst-case access delay of HomePlug Green PHY (HPGP) for delay-critical in-vehicle applications

The increasing complexity of automotive electronics has put considerable pressure on automotive communication networking to accommodate in-vehicle information flows. The use of power lines has been a promising alternative to in-vehicle communications because of elimination of extra data cables. In this paper, we focus on the latest HomePlug Green PHY (HPGP) which has been promoted by major automotive manufacturers for green communications with electric vehicles, and study its worst-case access delay performance in supporting delaycritical in-vehicle applications using both theoretical analysis and the simulation. Specifically, we apply Network Calculus as a deterministic modeling approach to evaluate the worst delay and further verify its performance using the OMNeT++ simulation. Evaluation results are also supplemented to compare with legacy methods and provide useful guidelines for developing HPGP based vehicular power line communication systems
