Abstract

From an environmental perspective, implementation and awareness of environmental sustainability are translated into sustainable development policies. To become a sustainable development, the performance of development must consider environmental, social, and economic factors based on living resources that ensure the quality of life of present and future generations. The rapid development of the city will always be followed by population growth. It will lead to land-use change, especially in areas that have potential land values ??for development. The Regional Government's role in controlling the conversion of land functions is by determining the allocation of agricultural land for food crops. However, the community often responds to this directive as discriminatory treatment because of restrictions on the right to build on their land, which is different from other people's land in areas designated for settlement and tourism. There is an indication of a common form of space utilization control. Besides, the principle of justice is not created for the people who own land for agricultural purposes. In terms of utilization, land allocated for agriculture cannot build buildings that are not following their original function, but landowners' incentives are not optimal. Likewise, investors who make villas and restaurants on land designated for agriculture are not subject to appropriate disincentives. This phenomenon that occurs in Canggu Village reflects that the control of spatial use listed in the RTRW direction of Badung Regency does not yet have the principles of justice and the principles of sustainable development. Concerning the preceding, as an effort to overcome the phenomenon while preventing further similar phenomena from occurring and protecting the values ??of social justice in society, management of spatial use control is required, especially on land designated for food crop agriculture.

Abstract

The southern side of Subak Babakan Yeh Kuning has an agricultural irrigation water shortage due to the dry season’s drought. In 2016, the Ministry of Public Works and Public Housing resolved that by giving diesel-powered irrigation water pump system and groundwater irrigation network, however the high operations cost resulted an abandonment of it. This study conducted a solar power plant design for submersible pumps at the southern side of Subak Babakan Yeh Kuning by calculating the amount of irrigation water needed, designing the solar power plant and the investment costs, and comparing the operations cost between the new and old system. Based on the design, the capacity of the solar power plant was set at 12,54 kWp using 33 solar module units and a 18,5 kW inverter unit. The pump could operate for 5 hours and 30 minutes on a sunny weather with a water discharge of 253 m3 or fulfill 17,5% of water needs for an area of 16-hectare. The investment costs of the solar power plant pump system were IDR 171.193.500. The operations cost of the new system (solar-powered) per hectare was IDR 6.495/day. Meanwhile, the operations cost of the old system (diesel-powered) per hectare was IDR 15.950/day.

Abstract

The internet has provided tremendous impact in educational development throughout the world. E-Exam system is one of educational component which has been used increasing dramatically for evaluating educational process. As an e-exam feature, uniformity of system access and time duration of the exam to all examinees is very important to be considered. Exam manager usually utilizes a fixed network to connect all e-exam terminal in order to maintain service stability on e-exam systems. However, the use of a fixed network will be difficult to be implemented if the number of examines is large. There are not many Education institutions have adequate ICT infrastructure or e-exam terminals for all students. Most institutions develop WLAN networks as an alternative to being able to provide ICT services to all students. With the development of mobile device technology (Handphone or Laptop) that strongly supports the learning process through mobile devices. This research aims to develop application of the Time Adaptive for Mobile E-Exam (TAMEx) Model. It serves to maintain the reliability of e-exam implementation on WLAN networks. The possible connection disruptions is anticipate by seeking time compensation only to participants who has experienced the connection problem. The time compensation must be accordance to the duration of the occurrence of connection loss. Application development has been carried out and is functioning properly. The report of application shows that it has succeeded in identifying the connection disturbance duration and provide time compensation to the proper examinee.

Abstract

Spatial Data Clustering is one of the most important technical techniques used to obtain information about knowledge about number boundaries in databases from various applications. This technique can determine groups of forms that cannot be arranged and can be used effectively with a budget. Exploring interesting and useful spatial boundary patterns is more difficult to extract traditional and categorical numerical polymers because of the difficulty of species, the relationship between autocorrelation of spatial boundaries. One of the pioneering techniques in the development of facial and technical grouping technologies is DBSCAN. This technique can determine groups of shapes that cannot be arranged and can be arranged in an effective way. the groups that have already received the next classification process are carried out in order to obtain information on the classes already formed. The K-Nearest Neighbour classification technique is based on learning by analogy. When there is new data, K-Nearest Neighbor will look for a class of data from the learning sample that is closest to the new data. This closeness can be defined using the Euclidean Distance calculation method.

Abstract

There are millions of different colors that exist in this nature. There are colors that can easily be distinguished from other colors, but many are also difficult to distinguish. The ability to distinguish colors is important in the recognition of an object, especially objects in an image. Color can be represented in a three-dimensional RGB color space and each color will have an RGB value with a range of values ??from 0-255. Conceptually, colors with different RGB values ??are different colors, but the human eye may not necessarily be able to distinguish them. This study aims to determine and measure the color dissimilarity that can be distinguished by humans. With an experiment comparing a color with a color made with a variation of RGB values, this study resulted that two colors that have a Delta E (?E) value of 8 can be distinguished by the eye. This result is obtained if both colors have a value of ?R, ?G or ?B of at least 8, or a value of ?RG, ?RB or ?GB of at least 6, or a value of ?RGB of at least 5.

Abstract

The study of digital image processing is still a hot topic in the realm of research, especially in medical research. The presence of various digital image processing methods and machine learning also contributes to the progress of research in this field. Detecting Covid Chest X-Ray is a prediction problem solving with a supervised classification method. In this study, the SVM method was chosen because it is proven to function as a good classifier as has been done in previous studies. Where previously the chest x-ray image feature extraction was carried out using wavelet transform. Feature extraction using wavelets has given the distinctive features of normal lung X-rays and distinguishes them from the distinctive features of Covid lung X-rays. The measurement results of the average classification model for the approximate, vertical, horizontal and diagonal dataset are 93.91% accuracy, 6.09% error rate, 98.75% recall, 89.06% specificity, and 91.26% precision. The vertical dataset is the best dataset to get a classification model because it has the best value in the accuracy and recall variables, but still provides good performance in measuring precision.
