Abstract

Increased evictions of agricultural land have an impact on current agricultural commodity production. Vertical farming/hydroponic systems in urban areas integrated with Photovoltaic (PV) are an alternative solution to two crises, i.e. land constraints and the concept of green energy. The research carried out aims to create a tool for monitoring environmental parameters in an Urban Farming Energy-Independent system that is integrated with the Internet of Things (IoT). The research began with (i) designing the electronic component board and interface of the Human Machine Interface (HMI) system, (ii) assembling and installing devices on hydroponics, (iii) calibration processes as well as device testing, and (iv) integration process with IoT. The monitoring device can run in two modes: manual or automatic. Parameters that can be monitored are water pH, water TDS, water height in the tank, temperature, and humidity.  The data entered on the device can also be monitored through the grafana platform. The accuracy of sensor readings on the device reaches over 98%.

Abstract

Research has been carried out regarding the evaluation of scattered radiation dose during CT scans of the thorax on the gonads and thyroid using 30 patients with CT scans of the thorax. In this study, the radiation dose received by thorax CT Scan patients was measured using TLD-100 which was placed at 3 measurement points on the patient. The first point was placed on the thyroid using 1 TLD, the second point on the thorax using 2 TLDs, and the third point was placed on the gonads using 1 TLD. The thorax CT Scan examination used a tube voltage of 120 kV. The results showed that the DLP and CTDIvol values ​​affected the value of the effective dose received. The average values ​​of CTDIvol and DLP were 6.268 mGy and 782.196 mGy.cm and the average thorax dose was 2.495 mSv. The average CTDIvol and DLP values ​​obtained in the study did not exceed the threshold set by the BAPETEN Regulation in 2021, namely the CTDIvol and DLP values ​​were 16 mGy and 810 mGy.cm. Radiation that affects the gonads and thyroid organs is scattered radiation. The average radiation dose received on the gonads and thyroid organs was 0.121 mSv and 0.485 mSv. The average dose value received did not exceed the dose received on the thorax and the radiation dose received on the thyroid was greater than the radiation dose received on the gonads. This is because the thyroid organ is closer to the irradiation area than the gonad organ.

Abstract

Magnetic susceptibility analysis of surface soil around Teluk Sirih Power Plant in Padang city has been conducted. Soil sampling was conducted at 28 points at a depth of 30 cm. The results show that the magnetic susceptibility value of surface soil range from 81.4667×10-8 m3/kg to 934.2133×10-8 m3/kg. The magnetic susceptibility value indicates that the surface soil around the PLTU is moderately to highly polluted, with several points of low pollution. The further from the PLTU, the lower the magnetic susceptibility value, indicating that the pollution comes from emissions from coal combustion at the PLTU. The further from the road, the lower the magnetic susceptibility value, indicating that there are other sources of pollution from vehicle emissions passing through the road. It also found that vegetation affects the level of soil pollution as indicated by the magnetic susceptibility value in the vegetated zone being lower than the magnetic susceptibility value in the non-vegetated zone.
