Abstract

Many people aspire to go on vacations, but their wishes often go unfulfilled due to the difficulty of managing the required budget for the trip. Additionally, they encounter challenges in selecting a holiday destination because well-known tourist spots tend to be crowded with visitors, leading to a less comfortable experience. These issues have sparked the interest of a research team in developing an application to address these concerns. The application is designed based on feedback obtained from a survey conducted by the research team. After processing and analyzing the survey results, the team has conceptualized an application called "Holiyay" to assist users in planning vacations within their predetermined budgets. The suggested travel destinations provided by the application are guaranteed to meet quality standards, ensuring a pleasant experience for users. To enhance the comfort of users during their vacations, the application will also offer the services of a guide called "Holiguide" to accompany them. In order to ensure security for both users and the application, a QR code will be provided to users when they book their vacation packages. This QR code will be scanned by the Holiguide to verify the identity of both parties, confirming that they are the designated user and guide provided by the application.

Abstract

Crowd has been a normal thing particularly in big cities. This could lead to negative causes such as slower mobilization or social anxiety towards individuals. Ever since the pandemic of Covid-19 lands all over the world, the application of thermal censoring devices has been commonly encountered in public places. The most common use of thermal censors is to detect human body temperature. Therefore, this research is done to analyze the effectivity of thermal cameras on detecting crowd inside a building. By using surveys and literature reviews as our methods, the result of this research shows that from 30 survey respondents, with the average age of 17-25 years old that tends to do indoor activities, 55.6% of them find that crowd is affecting their efficiency during activities. Besides that, 66.7% respondents struggle to measure the crowd level inside a building, also 87.3% of them feels like there should be a solution to this problem. Thus, this research proves that the use of thermal censors on camera for crowd detection is very effective with the accuracy rate of 99%. In conclusion, thermal censor devices are effective to be used as crowd detection devices.

Abstract

Communities in Jayapura use groundwater for their daily needs both from springs, dug wells and drilled wells. The research was conducted in the Sentani and surrounding areas. The purpose of this study was to determine the physical and chemical properties of groundwater based on laboratory tests. The physical and chemical properties of groundwater are one of the main properties of water and are very useful for determining the quality of groundwater. This study took three sampling locations with stratified random sampling method. The samples taken were springs, dug wells and drilled wells. The parameters of the physical properties of groundwater tested included pH, temperature ( T0C ), TDS, hardness ( CaCO3 ), while the parameters of the chemical properties of ground water tested included magnesium (Mg), calcium (Ca), potassium (K), Sodium (Na), Sulfate (SO4), Chloride (Cl) and Bicarbonate (HCO3). In general, all samples analyzed from the study area showed that the levels of chemical elements in groundwater had not exceeded the drinking water standard limits, but there were locations that had high levels of magnesium, namely location 1 (Sosiri) of 149 mg/L. The results of the physical properties test showed that the test content value had not exceeded the drinking water standard limit, in the sense that the groundwater in the study area was suitable for use.
