Abstract

Utilization of Information Technology in local Irrigation system in Bali called ‘Subak’ is expected to be able to distribute water evenly to all agricultural needs. Later, there will be no excess or even lack of water, no arable or infertile in the agricultural land due to water and its also expected to be able to produce maximum agricultural production. This study uses sensors of Soil Moisture, Soil Temperature and Soil pH which are expected to control water requirements for agricultural land which are flowed automatically by the system from the reports received by the sensor and the server using the Wireless Sensor Network. Water distribution will be carried out by the system after receiving water demand from sensors embedded in agricultural land using fuzzy logic so that the shared water will be the same as the Subak irrigation system but more controlled, effective and efficient. This may lead to better level of soil fertility required by plants as well as increase the agricultural output . The use of the Internet of Thinks (IoT) in this study will produce information that is fast and can be accessed on the Internet by using SmartPhone media, PCs or other communication devices.

Abstract

The use of physical server for Bank Mandiri branch office operations has several shortcomings, namely the high server procurement costs, limited part upgrading, maintenance costs, land requirements and electricity consumption. An alternative that can be used is cloud computing technology based on virtualization with the ROCCA adoption method. In this research, cloud computing is implemented to run the operational applications of Bank Mandiri branch offices using Microsoft Hyper-V virtualization. Then the performance and value of cost efficiency are compared to the physical server. Implementation results indicate the ROCCA method can be used for cloud computing adoption in the banking sector. Measurement of physical server performance reaches a score of 36% while the cloud server 9%, physical server memory reaches a score of 35% while the cloud server 50%, and the physical server harddisk reach a score of 48% and cloud server 52%. A higher percentage indicates better performance. Regarding to network speed, the physical server reaches a bandwidth of 94.9 Mbits / sec, while the cloud server 94.1 Mbits / sec. In terms of investment efficiency is not too significant, where in 5 years the efficiency value is 1.8% and for 10 years it is 2.81%.

Abstract

Sumber daya manusia merupakan salah satu faktor penting dalam sebuah organisasi yang mampu memberikan pengaruh besar pada organisasi. Pengembangan sumber daya manusia harus diukur untuk meningkatkan dan mencapai tujuan organisasi dalam menghasilkan sumber daya manusia yang berkualitas. Kinerja merupakan sesuatu yang dapat diukur dengan memberikan potensi dan kemampuan dalam menciptakan hasil dari tindakan yang dikerjakan. Untuk mengetahui tingkat kinerja dari sumber daya manusia yang dimiliki sebuah organisasi perlu dilakukan penilaian terkait kinerja atau kontribusi dari SDM tersebut. BARS adalah suatu metode dalam penilaian kinerja yang berdasarkan pada perilaku dari masing-masing individu. Penelitian ini bertujuan untuk mengetahui penerapan dari metode BARS dalam menilai tingkat kinerja pada organisasi swasta dan negeri. Hasil yang ditemukan menunjukkan bahwa penerapan metode BARS lebih banyak digunakan pada organisasi swasta dibandingkan dengan organsisasi negeri. Nilai yang ditunjukkan beberapa organisasi swasta lebih signifikan karena sudah mencapai dan hampir mendapatkan nilai tertinggi yang berarti melebihi tingkat nilai BARS dalam penilaian. Dalam hal ini organisasi swasta dan negeri memiliki harapan agar dapat menerapkan motivasi dan konstribusi yang baik dari setiap sumber daya manusia yang dimiliki agar mencapai tujuan dari organisasi.

Abstract

Captain I Wayan Dipta stadium rooftop power plant is designed as an additional power supply to meet the stadium's electrical load needs. Roof plts design using 2 scenarios. Scenario 1 has a capacity of 83,300 Wp with a solar module of 238 units and a 2-unit inverter generating 112,321 kWh/year of energy and will supply the day load of transformers 2 and 3 stadiums of 35,470 kWh/year. Scenario 2 with a capacity of 156,800 Wp with a solar module of 448 units and 4 inverters generates 211,458 kWh/year of energy and will supply the day load of transformer 1 stadium at 100,919 kWh/year. Scenario 1 investment cost of Rp.1,178,760,000 with total income up to 25 years amounting to Rp.1,090,635,084 while in scenario 2 costs investment amounting to Rp.2,237,860,000 and income up to the 25th year amounting to Rp.3,126,761,273 in economic feasibility analysis using NPV, PI, and the DPP is only scenario 2 which can be said to be feasible because in the 25th year the income is greater than the investment, while in scenario 1 the income will be worth the same as the investment in the 29th year. This means the system in scenario 1 is not feasible because it has a DPP longer than the lifespan of the project.

Abstract

Abstract—Image sharpening is an image optimization technique by combining two satellite images by taking advantage of each images, so that the output image has good spectral and spatial quality. Image sharpening is an alternative to facilitate the recognition of an object, moreover for Landsat satellites has many bands that can be used as samples for the image sharpening process. One method used in image sharpening is Brovey Transformation. This method is widely used because it is very simple and easy in making the algorithm. The Bands which is used in the image sharpening process are composite bands (red, green, and blue) with panchromatic bands from the Landsat 8 satellite. The results of the image sharpening process are high spectral images obtained from composite images and spatial values obtained from panchromatic images. Analysis of the results of image sharpening using the Brovey Transform method is done by comparing the quality of the truecolor image before sharpened and the image that has been sharpened by calculating the maximum and minimum values of the red, green and blue bands, analyzing the mean values and also the standard deviation values of each image. Key Words— Brovey Transformation, Composite, Image Sharpening, Landsat 8
