DATA VISUALIZATION TECHNIQUES: A REVIEW

Data visualization involves representing data and information in a graphical or pictorial form so that it can be easily understandable. At Present time, data is increasing at a very fast rate so, it is important to visualize and analyze the massive amount of data by using various visualization techniques. Data Visualization techniques are very helpful to visualize and understand outliers, trends, and patterns in data and thus helpful in decision making. This paper presents a review of the basic concepts of data visualization and various techniques and tools used for visualizing data. Some big data visualization techniques, which are the need of the hour, are also being discussed.

BUILDING USER SATISFACTION ANALYSIS TOWARD NEW ULM BANJARMASIN BUILDING IN 2020

The building is a physical form of the results of construction work that has a function as a place for humans to do activities. Every building that is built naturally has its own functions and uses. The ULM Banjarmasin building that has been built has finished its implementation period, where the maintenance period starts from the date of the first handover (PHO) for 12 months. But there is an agreement from the owner and the contractor where the building is used during the maintenance period in the trial period with a loan system that is operated during the maintenance period. When the function of the building is in operation, complaints of damage occur. Complaints about the damage in the form of building defects, some rooms have leaked, as well as the walls and floors that have cracked. In addition to dealing with physical damage to buildings, damage also occurs in facilities used by building users. These complaints trigger the dissatisfaction of building users during the usage period. This study aims to analyze user satisfaction with the new ULM building. This study is specifically for users of the building with 36 respondents who can be represented by students and staff employees. The analysis used is the Customer Statisfaction Index (CSI) of77% can be concluded that the user was satisfied during the use of the building in the maintenance period of the new building. Furthermore, with the Importence Performance Analysis (IPA) analysis, there are 7 variables that become the main priority in their subscription, which needs to be improved, i.e.there are pictures or floor plans of each building to get to the room to be obtained the results of satisfaction, quality of walls, sanitary and toilet accessories, roof / ceiling quality, fast and responsive in making repairs, sensitivity in complaints, friendliness and courtesy in repair services. Increased building user satisfaction is to tighten supervision of its workforce so that it can work optimally to prevent re-work and the need for training in operation of new buildings so that no damage is caused by the user at least minimizing the damage happens so users are satisfied as desired. Overall it can be concluded that the building user is satisfied.

DYNAMICS OF GAMMA RAY COUNTS RATE AND RADON GAS MEASUREMENTS IN TROPICAL REGION OF BRAZIL

In this experimental work, measurements of low energy gamma radiation are shown every minute and radon gas every hour during an uninterrupted period of six months. These measurements close to the ground were carried out in the city of São José dos Campos, ITA and IAE ground area in a tropical region of Brazil. Both measures show a correlation with day / night and dry and wet weather. It is observed from the measurements that most of the low energy gamma radiation originates from the exhalation in the region of radon gas and it vertical movement. During the period from January 27 to August 3, 2020, there were only six rainy intervals, the rest being very dry. These intervals are well revealed in the measurements of the local gamma radiation in energy range up to 10.0 MeV.

THE EVALUATION OF SLUM MANAGEMENT PROGRAM IN KEMUNING REGION, BANJARBARU CITY

The main obstacle currently faced in Indonesia urban settlements is the existence of slums area, as happened in Banjarbaru City. This is triggered by the high rate of urbanization which becomes the a strong pull factor for rural communities to move out to urban areas. They live in illegal land in the city and giving rise to slums. Urban settlements on legal land also have slum houses. This is mainly due to the fact that Minimum Service Standards (SPM) has not been implemented in the region. Looking at the social and cultural order in the environment, the communities that live in economically slum areas are generally low-income groups which are often the cause of moral degradation and politeness norms in various social structures. This study aim to understanding the characteristic of slums in Kemuning Region, evaluate the benefits of activities that have been built, find out if there are obstacles and how technical recommendations for handling slums next so that it can become a best practice. The method of research uses a quantitative approach and is a descriptive study that affects the slum environment in the Kemuning Area. This study is using primary data and secondary data. Primary data is obtained from interviews, questionnaires to the community and field observations related to the handling of slums in the Human Settlements field that had been built in the Kemuning Area. While secondary data is obtained from documentation that serve as supporting data and complement research support. This study suggested that Kemuning area has a typology of slums located on the edge of the water and lowlands, the evaluation of the utilization of slum area handling activities in Kemuning is deemed successful and beneficial as it is able to change the slums condition through handling contributions of 77.27% and technical recommendations for handling sustainability

SOLUTION OF SYSTEM OF ORDINARY DIFFERENTIAL EQUATIONS USING SHEHU TRANSFORM

Differential equations are fundamental and importance in engineering and mathematics because any physical laws and relations appear mathematically in the form of such equations. In this paper, we will discuss system of ordinary differential equations by using Shehu transform.

LAND SUITABILITY EVALUATION FOR A NUMBER OF ANNUAL CROPS IN THE TIWORO RIVER WATERSHED, MUNA, SOUTHEAST SULAWESI

The Tiworo River Watershed, which covers a total area of 29,047.82 ha, has been a resource for agricultural development for the local people of Muna, Indonesia. The information regarding the land suitability for annual crops in this watershed was, however, still very limited. A survey-based study was, therefore, conducted to evaluate the land suitability in the watershed for six annual crops (i.e. paddy-rice, corn, peanut, soybean, cassava, and tomato). The evaluation was based on Djaenuddin’s criteria, that was by matching the respective crop growth requirements against soil characteristics (e.g. soil pH, organic-C content, total-N, P2O5, K2O, CEC, base saturation, soil texture and drainage, rock outcrops, effective soil depth, and slope) and climate (e.g. rainfall, and air temperature and humidity). Soil characteristics were collected from 87 land units. A ten-year climate data series was gathered from the Betoambari weather station. The results of the evaluation showed that the land in the watershed fell into class S3 (marginally suitable) and class N (not suitable) for all the six crops evaluated, and no land units belonged to S1 (highly suitable) and S2 (moderately suitable). The main limiting factors found were low water and nutrient availability, and high erosion hazard.
