This study investigates the performance of the ESP-NOW communication protocol on ESP32 devices through field testing and Quality of Service (QoS) analysis. ESP-NOW is a lightweight, low-energy communication protocol that allows multiple ESP32 devices to communicate without relying on Wi-Fi. The objective of this research is to implement a program capable of measuring QoS parameters, including latency, packet loss, and Received Signal Strength Indicator (RSSI), across various distances. Field tests were conducted at Tanjungpinang, with devices positioned at heights of 2.5 meters and distances increasing at 10-meter intervals. The results indicate that ESP-NOW communication remains efficient up to 150 meters, with significant performance degradation beyond this range. Latency values ranged from 5.13 ms to 46 ms, and packet loss became substantial beyond 180 meters, with a maximum packet error rate of 99% at 300 meters. RSSI values showed a consistent decrease with increasing distance, falling to -97 dBm at 300 meters. According to TIPHON standards, the latency and packet error rate at closer distances were within acceptable limits, categorizing the protocol's performance as ‘Best’ for latency and ‘Perfect’ to ‘Good’ for packet error rate up to 210 meters. These findings suggest that while ESP-NOW is a viable communication protocol for short to medium distances, its reliability diminishes significantly beyond 200 meters. The study provides valuable insights into the limitations and capabilities of ESP-NOW, aiding users in making informed decisions about its application in various systems. This research supports the use of ESP-NOW in applications requiring robust and efficient short-range communication.

The Indonesian abalone industry has been experiencing growth in recent years and holds significant potential for further expansion. This paper provides a comprehensive review of the current state of the abalone industry in Indonesia, including production processes, markets, and trade, as well as the challenges and opportunities faced by the industry. The study found that the growth of the Indonesian abalone industry is driven by both the domestic market and the increasing demand for Indonesian abalone in international markets. Despite these opportunities, the industry faces various challenges, such as illegal fishing practices, intense competition, and fluctuating prices. The Indonesian government has implemented regulations to promote sustainable harvest and trade practices to address these challenges. The industry is focused on producing high-quality abalone to maintain its competitive position in the global market. The Indonesian abalone industry needs to overcome these challenges To sustain its growth in the future, expand its market reach through international trade, and continuously produce high-quality products. This review provides valuable insights into the Indonesian abalone industry and highlights potential future directions for growth. The findings of this study could be useful for industry players, policymakers, and researchers interested in the development of the Indonesian abalone industry.

Abstract BMP280 sensor is widely used to measure air pressure. Accuracy and precision are parameters used to indicate the performance of a sensor. This study examined the BMP280 sensor performance by measuring the air pressure on 15 sensors compared with BMKG devices as a reference standard. This measurement was conducted in BMKG class III Tanjungpinang from 20-22 May 2022. BMP280 Sensor performance analysis was performed using a statistical analysis one-way ANOVA method, Tukey test, linear regression, and root mean square error. Based on the results of one-way ANOVA, it is found that there is a BMP280 sensor that is different from the others. The Tukey test found that ID sensors 6 & 14 are not significantly different, ID sensors 1 & 4 are not significantly different, sensors 15 & BMKG are not significantly different, and sensors 3 and 9 are not significantly different. In addition, the results of linear regression and RMSE show an increase in the accuracy of the BMP280 sensor reading. Linear regression makes sensor measurement more accurate due to the small RMSE value.

Abstract The potential of sea waves, located precisely in the Berakit area, can be used as electrical energy on a small scale. Kelong is a floating house situated on the coast, which anglers (fishermen) use to catch fish. In the Bintan area, there are two types of kelong, namely floating kelong and cacak (permanent) kelong. Floating kelong, as the name implies, is a kelong that can be moved anywhere. During the fish season, the kelong are offered to the middle of the sea, but if the west wind season or not during the fish season, the kelong will be brought ashore. On the other hand, kelong cacak are usually not far from the beach or coast and cannot be moved and operated at night by using a lamp to catch cuttlefish or anchovies. This research was conducted on Kelong Cacak and Floating Kelong (pontoon) located in Berakit, Disability Telok Sebong, Kabubapen Bintan. The power generation system was built using the buoy method. Based on the research results, the wave power plant can be driven by sea waves with an average height of 6 cm and produces a voltage and continuously the voltage is not always stable. The maximum peak output voltage is up to 15 Volt DC; after knowing the test results, the power plant can supply as a charger for the battery in the kelong cacak of 0.8839 Volt DC with an average battery voltage of 10.052 Volt DC and total voltage charging is 0.37 Volt DC, with average battery voltage 11.4902 Volt DC on Floating Kelong (Pontoon).

In small island areas, people still use fossil fuel vehicles as their mode of transportation. This will cause environmental damage. One solution to this problem is developing the electric bike. This study uses a power-assisted bicycle type electric bicycle, consisting of a battery, a dc motor, a motor controller, and a throttle motor. From the test results, the motor can be used to support the rider. The problem is that the rated power is still more oversized than the engine can receive, where the temperature rises sharply from 30. 6 ° to 56.8°C in 21 minutes. The consequence was motor burnout because the motor forced to turn the front wheel over time. For right now, this e-bike suitable tourism bike in a short area so we can make sure the motor temperature did not exceed 50°C.

Ocean tides are the phenomenon of periodic sea-level change on the coast or in the ocean. There are a number of basic requirements that should be considered when planning to record the tidal data in the field, such as the length, the location, and most importantly the interval of observation. Unique features of Indonesian waters induce several types of tide observed. Focusing on the applicability of altimetry satellites in obtaining tidal harmonics to demonstrate the advantages of it. Hiring altimetry data from Topex and Jason series from RADS server could derive 25 years data of SSH. Using Formzhal-equation, the construction of tidal types has done. Mixed prevailing diurnal and diurnal types commonly found in the western part of Indonesia, while mixed prevailing semidiurnal types appeared in the eastern part.
