“…Kenaikan nilai kelembapan selama proses distribusi dikarenakan suhu dan kelembapan memiliki hubungan erat, apabila suhu berubah maka kelembapan akan berubah. Semakin rendah suhu udara maka kelembapan akan naik (Marni & Jumarang, 2016). Kelembapan relatif 85-90% disarankan dalam proses pematangan pada buah yang tingkat warnanya hijau dan sedikit berwarna kuning, akan tetapi harus diturunkan kelembapan relatifnya yaitu antara 70-75% jika tingkatan warnanya lebih banyak hijau daripada kuning.…”

Technological developments are used to provide product quality assurance and provide goods and services to consumers. Product quality is a condition related to the product, where the product could meet the needs and satisfaction of consumers. Product quality assurance, could be supported from raw materials, processes to distribution. This condition requires a tool that is able to control or monitor agricultural products by utilizing technology, namely the Internet of Things (IoT) using temperature, humidity, vibration, carbon dioxide (CO2) sensors and GPS that is able to show the location when the distribution process takes place in real time. The purpose of this study was to design and performance monitoring tools for temperature, humidity, vibration, carbon dioxide (CO2) and location during the distribution process. The results of the field test showed that the GPS sensor was able to show the location in real time according to the delivery route. The results of recording the highest temperature data was 30.8°C and the lowest temperature was 27.8°C, while the lowest humidity was 80% RH and the highest was 94% RH. The recording results from the SW-420 sensor showed that 51.04% for small vibration, 19.79% for medium vibration, and 28.64% for large vibration. The recording results from the MQ-2 sensor was able to show the carbon dioxide value around the tomatoes, with the lowest carbon dioxide with the value of 10% and the highest with the value of 23%.

Rain is one of the important hydrological components. Factors that affect the amount of rainfall in an area are temperature, air humidity, air pressure and wind direction. Previous research stated that there is a strong relationship between temperature and the amount of rainfall. This research was conducted to find out how strong the relationship between the amount of monthly rainfall that occurs in Padang City and the average temperature that occurs in each month for the last 30 years. The research method used is to use quantitative methods using descriptive statistics and non-parametric (spearman correlation test). The selection of the Spearman correlation test was carried out based on the results of the data normality test using the One Sample Anderson-Darling, Ryan-Joiner and Kolmogorov-Smirnov method. Data on temperature and rainfall for the city of Padang are not normal even though they have been normalized using the Box-Cox tranformation method. Spearmen's correlation test shows that there is no significant relationship between the amount of rainfall and temperature with a correlation level of only 9% with a P-Value of 0.087 > 0.05 or 0.001. Further research is needed to find out how strong other factors such as air pressure, humidity and wind direction are on the amount of rainfall in the city of Padang.

“…Universitas Tanjungpura merupakan perguruan tinggi yang berada di Kota Pontianak yaitu kota yang secara astronomis dilalui oleh garis ekuator. Posisi tersebut menyebabkan Kota Pontianak menerima lama penyinaran matahari yang panjang serta radiasi matahari yang tinggi, sehingga berdampak pada tingginya suhu udara pada kota tersebut (Jesiani et al, 2019). Kondisi iklim tersebut diindikasi dapat menimbulkan ketidaknyamanan termal bahkan dapat mengganggu kesehatan manusia karena suhu udara optimal manusia untuk beraktivitas adalah berkisar antara 20-27°C (Mintarto & Fattahilah, 2019).…”

This study aims to examine the level of thermal comfort of Tanjungpura University's green open space. The method used is to measure air temperature and humidity at seven green open spaces with three observation periods and then analyze it by calculating the Temperature Humidity Index (THI) value at each location. The results showed that the overall thermal comfort of green open space was still in the uncomfortable and partially uncomfortable category, with THI values between 25.61 to 28.93. In conclusion, there is a need for the development and enrichment of green open space vegetation in the Tanjungpura University area to increase thermal comfort for the academic community. Keywords: Thermal Comfort, Green Open Space, Temperature Humidity Index
