Riau Islands, which consists of thousands of islands and is located in the border area of Indonesia, has its own challenges. Based on this strategic geographical location, there are threats and opportunities to develop inter-island information systems. Wireless long-range communication is considered the most suitable for these conditions. Antennas are an important part of wireless communication. Research and fabrication of the Helix Quadrifilar antenna by utilizing the advantages and consideration of simple, lightweight and inexpensive materials, as the receiver antenna in inter-island communication systems. In this research, the design was carried out with the assist of the Antenna Magus software, measurements were using a Vector Network Analyzer instrument, and testing accomplished under the LOS conditions. The results are fabricated antenna optimum frequency shift of 433 MHz to 452.5 MHz, within 5.88% error percentage. The antenna fabrication, which is measured at a frequency of 433 MHz, obtained return loss -13.06 dB and VSWR 1.5, that meets the criteria of 1 ≤ VSWR ≤ 2. Quadrifilar Helix Antenna fabricated results can receive data from GPS sensors, temperature, humidity, air pressure, wind speed and wind direction of up to 9 kilometers. So that this antenna is suitable to be used as an antenna for inter-island UHF communication.

A measurement system is a process that consists of standards, employees, and methods for measuring particular quality characteristics. Measurement System Analysis (MSA) attempts to evaluate a measuring system's precision, accuracy, and consistency so that clients receive high-quality goods. The previous study implements the MSA for machinery and industrial lines, electronics manufacturing, agricultural and poultry, aviation, and even employee monitoring and inspection. Elsewhere, waste management has problems, especially with capacity measurement instruments and weight sensors. This study aims to: (i) build an IoT-based waste management system; and (ii) evaluate the developed system by implementing the MSA technique, focusing on measurement equipment. The Gauge Repeatability and Reproducibility (GRR) Study Type 1, the (GRR) Study, and the Analysis of Variance (ANOVA) are conducted to evaluate the measurement instrument of the waste management system. The study findings that the total variance of the GRR is 20.95 %, and the distinct categories are 6. Thus, as the Automotive Industry Action Group (AIAG) GRR recommendation, the measuring system is marginal (acceptable in certain conditions). Moreover, the ANOVA result indicates that interaction and operators did not affect measurement outcomes because the blue dots remain inside the acceptable range.

Object mapping based on location tracking methods has been widely used in various types of applications. Most tracking systems recently use existing technology and infrastructure such as satellite, cellular and wireless (RF) technology. These existing technologies are high-cost technology that needs authorized permission to be integrated to the novel technology. This research proposed a cheap point to point device technology to track a location of a transceiver using GPS in a portable infrastructure using Line of sight radio communication. The tracking system design is connected to the IoT system in order to be more accessible. The proposed system using GPS as an identifier of the transceiver coordinate location and 433MHz radio module as media communication between transmitter and receiver. The use of a 433MHz radio frequency module which is free-license adds value to the system so that it will be easily accessed. The design of portable and internet-based devices also gives a positive value in which the system does not have to depend on existing infrastructure and the system can also be reached even if it is placed in remote areas. The system test results show that the system can be well accessed up to a distance of 6.8 km.
