Indonesia is situated in the Coral Triangle region that has the worldâs highest coral reef biodiversity. Therefore, coral reef monitoring needs to be conducted regularly to assess the condition of coral reef ecosystem for management purpose. There are several coral reef monitoring methods available such as the line intercept transect (LIT), point intercept transect (PIT), photo transect, belt transect and benthic towed-diver. In Indonesia, LIT and PIT are the most commonly used methods for coral monitoring. However, there is a main disadvantage when collecting data using these methods, that is scientific divers need to spend hours to input the data after dives. Here, we introduce an electronic logging instrument called Coral Input Data Instrument that helps to decrease the input data time by employing a look-up table system that simplifies data input process by replacing text with numerical coding. In addition, water quality data such as temperature, depth and visibility also are embedded in the electronic logging instrument. The instrument hardware consists of Arduino Mega 2560, keypad 4x3, LCD Module 16x2 character, real time clock, temperature sensor, pressure sensor, visibility sensor and micro SD card module. Arduino IDE 1.6.5 software is used to program the microcontroller. In this paper, we describe the design and implementation of the instrument in the field.

Gastropod is a class of snail with the biggest number of species from the mollusk phylum, since it is able to adapt with any type of habitat. Watukarung Village, which has unique characteristic of its rocky beaches and sand dunes, is one of many habitats of gastropods in the intertidal zone. Thus, a basic information on the structure of the gastropods community in the area is required. Research was conducted in August 2014 in Ngalorombo Beach, Pasir Putih Beach, and Kasap Beach. Systematic sampling was applied using the quadratic plot of 1 x 1 m2, while data analyses comprised of density, Shannon-Wiener index, Eveness index, Simpson index, and correspondence analysis. The gastropods were found in studied areas consist of 8 families, 9 genera, and 13 species. The highest density and the most diverse of the category were in Kasap Beach. Eveness index and Simpson index of the species in the three beaches were in the low category. There was a tendency of the gastropods to live in the habitat made up of coarse sand and stones with good water quality, as shown in the result of the correspondence’s analysis.

Wilayah pesisir merupakan lingkungan dinamis yang dipengaruhi oleh interaksi atmosfer, daratan dan lautan. Demikian pula, posisi garis pantai juga selalu berubah karena komponen alami dan ulah manusia seperti erosi, gelombang, pasang harian, badai, dan pembangunan yang terjadi di kawasan pesisir. Dalam literatur, posisi garis pantai dapat diidentifikasi berdasarkan berbagai proxi seperti: fitur pantai yang diidentifikasi dari foto udara atau citra resolusi sangat tinggi dan indikator berbasis datum pasang surut yang diekstraksi dari survei lapangan. Penelitian ini mengusulkan suatu metode dalam memodelkan garis pantai berbasis datum dengan mengintegrasikan berbagai data batimetri termasuk data single beam dan multibeam echo sounding, Digital Elevation Model Nasional, data batimetri nasional dan data batimetri yang dihasilkan dari citra satelit. Metode stacked curve spline tension diterapkan untuk mengasimilasi berbagai data batimetri tersebut dan untuk membangun garis pantai. Berdasarkan hasil uji akurasi diperoleh kemiripan garis pantai yang bervariasi akurasinya yaitu garis pantai LAT memiliki tingkat akurasi sebesar 29.28%, garis pantai MSL sebesar 65.45% dan garis pantai HAT sebesar 47.48%. Variasi akurasi yang diperoleh dapat terjadi karena beberapa hal diantaranya minimnya data input kedalaman yang digunakan, kerapatan data kedalaman yang sangat bervariasi, perbedaan waktu perolehan data antara data yang digunakan untuk penyusunan Peta LPI dan data yang digunakan dalam penelitian ini. Meskipun hasil uji akurasi yang diperoleh masih kurang memuaskan metode yang disusulkan ini cukup menjanjikan untuk diadopsi sebagai metode alternatif dalam pembangunan garis pantai dan untuk mengatasi keterbatasan data, waktu dan biaya dalam penyediaan garis pantai nasional.

Sea level is one of ocean properties that needed to be observed. Sea level observation will give information about osean tides and tides datum. As technology became more reliable, people can develop new instrument easily. Recently, open source microcontroller “Arduino” became popular and lot of people using it to develop what we call “low-cost” instrument. But, there are several disadvantages if we build instrument directly. Simulation phase must be done before manufacture instrument. This phase will help to decrease cost and time. In this paper, we will describe the concept, algorithm, and simulation phase in manufacturing Low Cost Ocean Tides Monitoring Instrument.

A battery, also known as an accumulator, is an electrical cell that can reverse an electrochemical process with high efficiency. It is essential in the use of electrical systems as storage devices. It has two critical parameters: current and voltage. These parameters can affect the battery's behavior, which leads to battery usage. As a result, a battery monitoring instrument is required to monitor the battery's current and voltage while it is in use. The researchers designed a monitoring instrument with an Arduino Pro Mini 5V microcontroller as the main processor, INA219 as a current and voltage sensor, RTC DS3231 as a time reader, micro SD card module as a data logger, and OLED SH1106 to display the current, voltage, and time readings. The calibration of the INA219 sensor has a current reading accuracy of 91.43% and a voltage reading accuracy of 99.87%. RMSE was measured at 227.65 mA and 0.0146 V. The device was tested with a BSB DB 12-55Ah battery connected to 30W PJU lamps. In the results of this test, we experienced voltage drop and current ripple in the battery performance. The battery usage capacity was 49.71 Ah. Based on this research, the device built can monitor battery conditions.

The aim of this research is to develop an automated instrument for filtering surimi washing wastewater. The tool consists of a water suction system, a filtration system using a plankton net, and temperature sensors DS18B20 and distance sensors JSN-SRT04. The results show that the automated surimi washing wastewater filtering instrument has been successfully developed and can produce 343 grams and 199 grams of filtered meat from 1 kg of meat in two trials. The water turbidity data before and after the filtration process also shows that the instrument can reduce turbidity by 88% allowing the surimi washing wastewater to be reused. This demonstrates that waste reduction can be applied to this instrument. Data from DS18B20 temperature sensor and JSN-SRT04 distance sensor also show accurate and precise data patterns. DS18B20 calibration shows average error by 2.51%, RMSE by 1.47 ?C, and standard deviation by 0,7 ?C. JSN-SRT04 calibration shows average error by 3.07%, RMSE by 1.99 cm, and standard deviation by 0.45 cm. Therefore, the automated surimi washing wastewater filtering instrument is an effective solution for utilizing surimi washing wastewater and reducing liquid waste. The implementation of this tool would be very beneficial to the surimi processing industry in reducing waste and preserving the environment. This instrument can also be used as a reference for developing other automated instruments in the field of wastewater treatment. Key Words: Surimi, zero waste, acoustic sensor, temperature sensor

Monitoring sea level is important for assessing climate change impacts, coastal management, and predicting hazards. Accurate measurements of air pressure is essential for precise sea level monitoring through pressure-to-altitude conversion. Additionally, understanding tidal patterns and their dominant components is crucial for comprehensive sea level analysis. This research aimed to investigate the accuracy of BMP280 and BME280 sensors in measuring air pressure and altitude to monitor sea level. Comparing air pressure data from the BMP280, BME280, and BMKG sensors showed that the BMP280 sensor had a higher accuracy than the BME280 sensor. Linear regression was used to decrease the error value. After calibration, BME280 and BMP280 did not differ with the BMKG sensor using one-way ANOVA and Tukey test. A field test was also conducted to assess the ability of the BMP280 sensor to measure sea level height from air pressure conversion. It was found that the BMP280 sensor could not provide an accurate sea level height value with an R² value of 0.00931. A Fourier analysis was used to investigate the tidal pattern in Tanjung Siambang using six constituents, symbols S1, O2, M2, S2, S4, and S6, with periods of 24, 12.91, 12.42, 12, 6, and 4 h. It revealed that the dominant components were M2 and S2, caused by the moon's and the earth's gravitational pull. This study highlights the limitations of the BMP280 sensor in providing accurate sea level height measurements and the importance of the M2 and S2 tidal components in determining sea tides in Tanjung Siambang.
