: The purpose of open space is as a forum for organizing activities that are not only limited to human activities but also as a forum for nature conservation Papan Island has the potential as a tourist destination with its cultural wealth and biodiversity, by creating a space for tourists and still paying attention to the needs of the people of Papan Island and its environment, a tourist area will be created with the concept of Green Open Space (RTH) Method: The method used in this research is the Architectural design method. This method uses an analysis of the activities and needs of tourists and the community on Papan Island. Data obtained through interviews, observations, documentation, and literature studies Results and Discussion: This research makes the concept of shared space in architecture refer to an area or environment designed to be used and enjoyed together by a group of people. Based on the results of the analysis that has been carried out, the following design response will be made, namely making flexible openings such as large sliding door openings but at the same time can be closed.

E-Surveillance System Security Using RSA-AES Algorithm (Rivest Shamir Adleman - Advanced Encryption Standard)

2024-06-26T15:14:38+00:00

Introduction: The Regional Inspectorate of Central Sulawesi Province has the task of supervising and fostering the implementation of government such as conducting audits, evaluations, reviews, and monitoring. The Regional Inspectorate of Central Sulawesi Province built a system for fostering Regional Apparatus Organizations called the E- E-Monitoring system. However, the files uploaded by the Regional Device Organization have not been encrypted in this system, so this study aims to use the RSA-AES algorithm in the E-Pengawasan system to increase system security.

Method: The process that occurs in the RSA-AES algorithm is that the RSA key is used to encrypt the AES key and the AES key is used to encrypt and decrypt the file.

Results and Discussion: The test results used are the black box testing method and also usability testing. Black box testing is used to test whether the functions on the system are running smoothly or not and usability testing is used to test efficiency in encryption and decryption based on file size.

Conclusion: Based on the tests carried out, it was found that the amount of time used to encrypt files with a file size of 1MB - 50MB was 0.182 - 0.393 seconds. The test results for decryption were found with a file size of 1MB - 50MB, namely 0.050 - 0.148 seconds.

2024-06-26T15:14:39+00:00

Research has been carried out on the effect of eco enzymes on television electromagnetic radiation. This research aims to determine the amount of electromagnetic radiation on live television before and after using an eco enzyme. Measurements were made of the amount of electromagnetic radiation from the television when it was off, and the television when it was on before and after using eco enzyme, using 2 types of eco enzyme (pineapple eco enzyme and organic material eco enzyme) with a volume of 1 liter (for 1 bottle) and 2 liters (for 2 bottles). The position of the eco enzyme with the surface of the bottle cover open is placed in front of the television screen at a measuring distance of 25 cm, 50 cm, 75 cm, 100 cm, 125 cm, 150 cm, 175 cm, and 200 cm. Television electromagnetic radiation in the form of the highest electric field and magnetic field when the television is on before using eco enzyme at a measuring distance of 25 cm respectively is 30 V/m and 0.22 μT. After using the eco enzyme, the highest reduction in electromagnetic radiation occurred at a measurement distance of 25 cm. Treatment using 2 liters of pineapple eco enzyme can reduce television electromagnetic radiation in the form of electric fields and magnetic fields respectively, namely 6 V/m and 0.18 μT. In the treatment using eco enzyme, a variety of organic materials with a volume of 2 liters can reduce television electromagnetic radiation in the form of electric fields and magnetic fields respectively, namely 7 V/m and 0.19 μT.

Determination of Slope Safety Factor Based on Hoek & Brown Collapse Criteria on Ampera-Surumana Road Section

2024-06-26T15:14:39+00:00

Introduction: One way to determine whether a slope is stable or not is by using the safety factor criterion. The method to determine the safety factor using the limit equilibrium method. Administratively the research area is located in the village of Salubomba, Central Banawa District, Donggala Regency, Central Sulawesi Province. The results of the study are also expected to be used as one of the basis for planning the design of stable slopes in the area Method: The methods used in this research were qualitative and quantitative. The process in this research was carried out with each method. The process of collecting secondary data and primary data is carried out by Geology and Geological Engineering methods both qualitatively and quantitatively. Results and Discussion: Observations in this study were made in the field in the form of observations of bridging on road slopes. The bruises in the study area are grouped on the basis of their shape and genetics. Through the results of observations and measurements on rock slopes at the research site. Based on data processing on the GEOSTUDIO 2018 R2 software application. Then, the value of the slope safety factor at observation station 1 is 2.316. Conclusion: Based on testing and analysis of the Hoek & Brown collapse criteria method, it can be concluded that the value of the slope safety factor at observation stations 1, 2, 3, 4, and 5 is 2.316; 2.029; 1.765; 1.658; 2.622 respectively. At station 4 the level of vulnerability is medium (Landslides can occur), at station 3 is at a low level of vulnerability (Landslides rarely occur), while at stations 1,2 and 5 are at a very low level of vulnerability (Landslides very rarely occur).

This research was conducted in part of Palu Bay which is included in the administrative area of Palu City. The problems in this study are: (1) How is the change of coastline in some parts of Palu Bay? (2) How much area was affected by the Tsunami in parts of Palu Bay? This study aims to: (1) To know the changes of coastline in some parts of Palu Bay. (2) Know the area affected by the Tsunami in part of Palu Bay. This type of research is quantitative descriptive research. The method used to obtain data is by using Geographic Information System (GIS) analysis with overlay techniques.

Effect of Food Safety Education on Knowledge, Attitude, and Behavior of School Community and Retail Community in Ampibabo Sub-district

2024-06-26T15:14:41+00:00

Food safety is a condition to prevent food from possible biological, chemical, and other contaminants that can harm and endanger human health. This study was conducted to determine the effect of food safety education on the knowledge, attitudes, and behavior of the school community and retail community before and after the intervention. This type of research is an experimental study with a total sample of 60 people from the school community and 54 people from the retail community. This research began in March-October 2021. The analysis used in this study was the Wilcoxon analysis with the SPSS application. The results of the effect of food safety education on the school community in aspects of knowledge, attitudes, and behavior with the value of Sig. (2 tailed) < 0.05 consecutively 0.030 < 0.05; 0.000 < 0.05 and 0.000 < 0.05. H0 is rejected so that there is an effect of food safety education on food safety knowledge, attitudes, and behavior. The effect of food safety education on the retail community on the knowledge aspect with a value of 0.000 < 0.05, which means that there is an effect of food safety education on the knowledge aspect of the retail community. While on the aspect of attitude and behavior aspect with the value of Sig. (2-tailed) < 0.05 0.106 > 0.05 and 0.363 > 0.05, which means that H0 is accepted, so there is no effect of food safety education on aspects of attitude and behavior in the retail community. The conclusion obtained is that there is an effect of food safety education on the knowledge of attitudes and behavior of the school community, there is an influence towards a better direction after food safety education is carried out on aspects of knowledge of the retail community and there is no effect of conducting food safety education on aspects of attitudes and behavior of the retail community.
