Abstract

Koi fish (Cyprinus carpio), or commonly known as nishikigoi, is one of the ornamental fish that is in great demand by the public today, because koi fish has a very beautiful uniqueness, both in terms of shape, pattern, and color on the body of the koi fish, that it has a high selling price. Maintaining koi fish is a small-scale cultivation activity, which is currently popular with the public during this pandemic, but maintaining a koi fish is complicated because there are many factors that need to be considered so that the health of koi fish is maintained, especially where koi fish live in the form of water. Basically, fish will live and breed in an aquarium properly if the environmental conditions provided in accordance with their living conditions can be met or close to their natural habitat, one of the water parameters that needs to be considered is salinity. Koi fish are sensitive to salt concentrations in their environment and have developed systems that maintain a constant balance of salt ions in their bloodstream through the movement of salts and across gill membranes. Koi fish have a minimum salinity level of 2 ppt and a maxi

Abstract

Aerator is a machine that produces air bubbles that functions to move water in the pond so that the water is rich in dissolved oxygen which is needed by all freshwater fish. The working principle of this tool is to make the surface of the water as much as possible in contact with the air. The goal is that the oxygen content in the water is sufficient and gases and impurities that usually cause rot can be expelled from the water. These air bubbles are very important for fish because these bubbles act as oxygen for fish. This oxygen level is commonly called DO (dissolved oxygen). Many ornamental fish entrepreneurs, especially koi, underestimate the level of dissolved oxygen in water (the use of aerators) both in terms of power consumption, which is not regulated or does not provide a tool in the form of an aerator. For this reason, this research makes aerator speed settings according to the needs of the fish and also saves costs because it does not have to be turned on every time.Keywords: Aerator, koi fish farming, DO, dissolved oxygen in water

Abstract

Koi is one of the largest contributors to ornamental fish exports based on data from the 2014-2018 KKP, koi exports have increased from 767 kg in 2017 to 2,162 kg. The high demand for koi encourages cultivators to increase their koi fish farmingbusiness. Koi live in freshwater waters with a pH ranging from 7.5 to 8.5 with a tolerance of 6-9 in calm water currents and have many aquatic plants. Continuous monitoring of water quality, especially pH levels, is very much needed. Monitoring the pH level of water in fish farming ponds is currently still done using the manual method, namely by measuring directly to the aquarium which takes a long time and is inefficient. So that this problem can be overcome, a pH control device in the aquarium is made that can monitor and control pH levels continuously in the aquarium. Controlling pH levels in aquarium water is done by giving a certain amount of acid (pH down) or alkaline (pH up) solution that can increase and decrease pH levels so that the pH in aquarium water is always stable in a predetermined range. The acid or base solution is sucked up by a water pump motor to be discharge

Abstract

Crop failure due to high rainfall is a threat to farmers. One solution to overcome this problem is to cultivate melons in a greenhouse. However, this can result in a significant increase in temperature so that the soil in the planting medium dries quickly. In this study, an algorithm was implemented to control the readings of dissolved water content in the planting medium by non-invasive capacitive sensor pieces which were carried out alternately using a decoder, as well as reducing reading noise using the Kalman Filter algorithm. The algorithms designed include reading sensor data every 50 ms, changing each capacitive sensor plate so that it can act as an excitation source, sensing element, and shield in turn, reducing noise reading from the sensor, sending sensor reading data from Arduino Nano to ESP32, receiving and parsing the data according to the data sent by the Arduino Nano, and turning on or off the fertigation system according to the data obtained. Based on the test results showed that the water content read on the capacitive sensor without planting media

Abstract

Melon is a widely cultivated fruit because it only takes 60 days until harvest time. One of the biggest threats to melon farmers is crop failure. Melon cultivation in a greenhouse is one solution to overcome this problem. One of the parameters monitored is the water content in the planting media. A non-invasive capacitive sensor is used to read the soil moisture value evenly. This capacitive sensor works like a capacitor, with the planting media as a dielectric material that is placed between the electrode plates. The sensor requires a signal conditioning circuit to convert the capacitance value of the sensor into a DC voltage so that it can be read by the ADC. this circuit has specifications such as: the ability to generate an output in the form of DC voltage, ability to generate different output value for the different condition of planting media, and ability to be read by microcontroller's ADC. The test is carried out on the Signal Conditioning Circuit which consists of: De Sauty bridge circuit, full-wave rectifier circuit, and operational amplifier circuit. The results s

Abstract

Royal Jelly is a nutritious food that has many benefits, thus increasing the demand for the product. Royal Jelly can be produced by bees 121 times/year, but the large amount of production is not matched by a good harvesting system, namely using the conventional method by prying out the queen cup. If the harvesting process is carried out in large quantities, farmers will have difficulties and have an impact on product quality, when the harvest time of royal jelly is getting longer, the quality of royal jelly will decrease, especially in the aspect of viscosity. Then an automatic royal jelly harvester is needed to speed up the harvesting process. In an automatic royal jelly harvester, a system that can detect and measure the distance of royal jelly is needed, namely by image processing using a camera. The results of the RGB segmentation test were obtained with a binary image thresholding value with a lower limit (220,220,220) and an upper limit (255,255,255) while the HSV method obtained a binary image thresholding value with a lower limit (0,0,240) and an upper limit (179,80,255). The detection rate of the HSV color space method gets 100% accuracy compared to the RGB color space method which gets 60%. In addition, measuring the distance of Royal Jelly with millimeters using a camera can be done using the Euclidean distance method and the percentage of error is relatively small (3%) from the actual distance.Keywords: Royal Jelly, Image Processing, Eclidean Distance

Abstract

Royal jelly is one type of bee product that has many benefits and high nutritional content. The characteristics of royal jelly are classified as easily damaged if the queen cup is left open for a long time, so the quality of the royal jelly produced is not good. Poor quality will affect the important ingredients in royal jelly which can reduce the amount of royal jelly production. Unfortunately, the harvesting tools used today do not have measurements and monitoring of the composition of weight and royal jelly that support it. Therefore, the purpose of this research is to design a monitoring system for weight and sucrose in royal jelly based on the Internet of Things. The system is equipped with accurate measurement of sucrose content, measurement of harvest weight, and real-time data transmission that is stored through the database. Measurement of sucrose level monitoring was carried out using the TCS-230 sensor resulting in an error percentage of 3.002% and was in accordance with ISO standards. In addition, the results of the measurement of the first harvest weight of 26.2 grams then increased until the fifth harvest, which was 113.2 grams. With Internet of Thingsbased monitoring, the value of sucrose content, weight, time, and date that can be seen through the android application aims to make it easier for users to view incoming realtime data and automatically recap data.Keywords: Royal Jelly, Sucrose, Weight, Internet of Things.

Abstract

Royal Jelly is a product produced by honey bees and has many benefits, thus increasing the demand for the product. This high demand is considered not effective because the harvesting system is is carried out using conventional method, by removing one queen cup at a time. If the harvesting process is carried out in large quantities, farmers will have difficulties and this will impact on product quality, because the amount of royal jelly increases within 72 hours, but begins to decrease after 96 hours of larva removal. Therefore, an automatic royal jelly harvester is needed. In this research, the process of designing back up power and setting the conveyor speed. The results of this study, it can be seen that the system is capable of for 30 minutes using an accumulator, when the power goes out. While on the conveyor speed system, the conveyor is able to run at the desired speed according to the in the specified distance range, so that the queen cup object can stop at a position that can be reached by the royal jelly suction for the harvesting process.Keywords: Royal Jelly, Back Up Power System, Duty Cycle, Conveyor

Abstract

This study discusses how to reproduce HHO (Hydrogen Hydrogen Oxygen) gas by water electrolysis process with electrolyzer wet cell or wet type. The method used in this research is experimental. The design of this tool is divided into 3 main stages, manufacture of containers, manufacture of water traps, and manufacture of gas flowmeters. The container measuring 120 mm x 100 mm x 140 serves as a place for the process of separating water molecules (?2?) into its constituent compounds, namely hydrogen (?2 ) and oxygen (?2 ) or it can be called water electrolysis. The electrode used is a graphite with measuring of graphite electrode is 140 mm x 20 mm x 20 mm. 20 grams of Potassium hydroxide (KOH) serves as a catalyst to help accelerate the process of separating water molecules in electrolysis. The container will be connected to a water trap and then a gas flowmeter or gas measuring instrument. This study shows that designing a wet type HHO gas generator with a pure DC source and a PWM source will have a correlation between HHO gas production and variations of the distance between two electrodes. At a distance of 2 cm the electrode produces HHO gas of >1200 ml with a pure DC source within 15 minutes. For an electrode distance of 4 cm the HHO gas produced is 1200 ml with a pure DC source within 15 minutes. And for an electrode distance of 6 cm the HHO gas produced is 880 ml with a pure DC source within 15 minutes. Meanwhile, at a distance of 2 cm from the electrode with a PWM source of HHO gas, the resulting HHO gas is >1200 ml in 15 minutes. For an electrode distance of 4 cm with a PWM source of HHO gas, 1030 ml is produced in 15 minutes. And for the electrode distance of 6 cm with a PWM source of HHO gas, 690 ml is produced in 15 minutes.Keywords: electrolyzer wet cell, HHO gas, distance of electrodes

Abstract

Water quality is the main parameter in the cultivation of freshwater ornamental fish and marine ornamental fish. To get healthy ornamental fish, water conditions must be maintained, one of which is the pH of the water. Generally fish need a water pH in the range of 6.5 to 8.5, which is considered the optimal range for good fish growth. Changes in the pH of seawater can adversely affect the life of marine biota, either directly or indirectly. Controlling the pH of water in marine ornamental fish using the Mamdani fuzzy logic method, by determining its membership function so that it can control the speed of pumping acid or alkaline solutions. From the results of the study, the tool can control the pH of seawater according to the setpoint membership function that has been set, namely 6.5-8.5 for 368-478 seconds by adjusting the pump output discharge according to the difference between the pH of the aquarium and the desired value.Keywords: pH, Fuzzy Logic Mamdani, Membeship Function
