Abstract

Evaporation boats waste is a waste that is difficult to decompose which has characteristics as a material for makingowi, but its utilisation is still not optimal. The purpose of this study was to determine the effect of compaction pressure on the thermal conductivity and microstructure of aowi made from evaporation boats, kaolin and rice husk charcoal. The research method used was experimental. The independent variable used in this study is the kowi compaction pressure with variations of 20 MPa, 25 MPa, 30 MPa, 35 MPa. The composition of the materials used is 50% evaporation boats, 35% kaolin powder, and 15% rice husk charcoal and 15% water from the total weight of the materials in the mixing. The dependent variables in this study are thermal conductivity testing and microstructure observation. Control variables in this study are powder particle size 100 mesh, mixing time 90 minutes, thickness 2 and 4 mm, specimen diameter 40 mm, firing temperature used 8000C, and holding time 2 hours. The results showed that the average value of the highest thermal conductivity of 4.1045 W / MK at a compression pressure of 35 MPa and the lowest thermal conductivity value of 3.3499 W / MK at a compression pressure of 20 MPa. The higher the compression pressure, the greater the value of thermal conductivity. This is because the greater the compression pressure, the stronger the bond between particles and pores are reduced so that the density increases. The microstructure shows a difference in phase at each compression pressure given. The greater the compression pressure applied, the tighter the density of the material. Keywords: Compression Pressure, kowi, evaporation boats, kaolin, rice husk charcoal, thermal conductivity, microstructure

Abstract

Fish hatcheries are a significant endeavor in aquaculture with promising economic potential. However, the manual process of counting fish seeds is time-consuming and inefficient. This paper examines a prototype of a fish seed counting device based on a Programmable Logic Controller (PLC) and Human Machine Interface (HMI) that can expedite the counting process. The device is designed using infrared proximity sensors, a DC power window motor, a solenoid valve, and is controlled by a PLC and HMI. The infrared proximity sensor is placed under the fish passageway to detect fish presence. The counting results are displayed on the HMI screen. After counting, the DC motor closes the fish passageway, and the fish in the plastic packaging are automatically tied for oxygen filling. Testing results indicate that this fish seed counting device functions well and can improve the efficiency of the fish seed counting process

Abstract

The performance of a biomass-assisted recirculating mixed-flow dryer for drying paddy (Oryza sativa L.) was thoroughly assessed. The dryer system comprises a biomass furnace, drying column, vibratory feeder, bucket elevator, and blower. In the experimental setup, the drying time required to reduce the moisture content of paddy from 20.90% (wet basis) to 13.30% (wet basis) was measured at 4.5 hours. During this period, the average air temperature was recorded at 78.15 °C, accompanied by an average relative humidity of 8.55%. The observed drying rate ranged from 1.688 to 18.126 kg/h, with an average value of 7.792 kg/h. Further analysis revealed that the specific moisture evaporation rate (SMER) and specific energy consumption (SEC) varied between 0.122 and 1.308 kg/kWh, and 0.806 and 8.657 kWh/kg, respectively. The corresponding average values were 0.562 kg/kWh for SMER and 4.119 kWh/kg for SEC. The thermal efficiency of the dryer, along with exergy efficiency, demonstrated a range of 7.82% to 83.99% and 15.28% to 25.64%, respectively. The average values for thermal efficiency and exergy efficiency were calculated as 36.11% and 19.46%. Meanwhile, the efficiency of the biomass furnace ranged from 70.63% to 87.70%, with an overall average efficiency of 79.53%.

Abstract

The demand for electrical energy is increasing. Electricity supply in Indonesia is not yet evenly distributed. Indonesia's electrification ratio is only 99.63%. Generally, areas that have not been electrified are rural areas. It is necessary to utilize water energy sources for power generation. This research was conducted with a simulation tool from a micro hydro power plant with a crossflow turbine. The use of this turbine is because it is easy in terms of cost and manufacturing. The research was given an input source from a pump with a double pump system and a single pump system. Each system is given a variation of 100%, 75% and 50% openings. Data collection time is carried out for 90 minutes on each system and opening. From the research results obtained current, voltage, and output power. In the double pump system with 100% opening is relatively greater than 75% and 50% opening in the same system and in the single pump system. The maximum output current obtained in this study is 0.09 amperes with a double pump system opening 100% and the minimum output value is 0.02 amperes in a single pump system opening 50%. The maximum output power obtained in this study was 1.81 watts with a 100% opening dual pump system and a minimum output value of 0.32 watts in a 50% opening single pump system. The maximum output voltage obtained was 21.5 volts at 50% opening of the dual pump system, and the minimum output voltage was 15.8 volts at 50% opening of the single pump system. A large discharge will provide a large current, voltage and power output because it is able to crush the turbine with a relatively large speed. Discharge will affect the pressure and flow that occurs in the pipe, because the amount of discharge will be linear with the amount of pressure. The use of double pumps will get high efficiency with a large discharge. The greatest efficiency occurs when the double pump system.

Abstract

This research aims to determine the effect of seawater on concrete durability and to assess the compressive strength of concrete based on variations in concrete mixtures and curing methods. The tests conducted include testing the characteristics of coarse and fine aggregate materials to obtain accurate concrete mix planning, followed by compressive strength testing after curing for 3, 7, 14, 21, and 28 days with four different mix and curing variations. The results show that in variation 1, the compressive strength of concrete cured with seawater for 14 days was 9.81% higher than that cured with freshwater. In variation 2, the compressive strength of concrete mixed with seawater and freshwater cured for 3 days was 43.91% higher compared to seawater curing. In variation 3, the compressive strength of concrete with a freshwater-seawater mix cured for 14 days was 44.65% higher than that of the seawater-only mix. In variation 4, the compressive strength of concrete with a seawater-freshwater mix cured for 3 days was 15.54% higher than that of the freshwater-only mix.

Abstract

Indonesia is experiencing significant traffic load growth; however, this is often not matched by the development of adequate road infrastructure. This phenomenon occurs because traffic load growth is faster than the development of road infrastructure. Excessive traffic load can cause damage to the roads. Aggregates, especially fine aggregates, play an important role in flexible pavement layers, particularly in the AC-WC layer. The AC-WC layer aims to provide smoothness, safety, and comfort for road users while protecting the underlying layers from damage caused by traffic loads, such as subsidence, ruts, and asphalt deformation. The use of silica sand has become one alternative to improve the quality of the AC-WC layer. This study aims to obtain the Optimal Asphalt Content (KAO) value and the Refusal Optimal Asphalt Content (KAO) value. The KAO value using the Marshall method in the AC-WC mixture is 5.99% for 0% silica sand variation, 5.88% for 25% silica sand variation, 5.845% for 50% silica sand variation, 5.835% for 75% silica sand variation, and 5.810% for 100% silica sand variation. The Refusal KAO value is 5.920% for 0% silica sand variation, 5.83% for 25% silica sand variation, 5.785% for 50% silica sand variation, 5.750% for 75% silica sand variation, and 5.775% for 100% silica sand variation. Thus, the greater the percentage of silica sand added as a substitute for fine aggregates in the AC-WC mixture, the lower the Marshall KAO and Refusal KAO values obtained.

Abstract

This research aims to design and analyze a portable cold storage system that uses solar energy as the main power source. The research methods used include literature studies, system design, and design analysis to evaluate the performance of the cold storage being designed. The designed system has a volume of 2.93 liters with an operational temperature of -2°C, which requires a total energy requirement of 114,912 kWh per day to maintain storage temperature stability under external environmental conditions of 30°C. The solar panels used have an efficiency of 18% with a standard irradiation exposure of 1000 W/m², capable of producing 4,788 watts of power, which shows sufficient efficiency to meet the cold storage energy needs. Based on the analysis, it is estimated that 43.2 solar panels are needed to meet daily energy needs, which indicates the large scale of energy infrastructure needed to maintain cold storage operations 24 hours a day. In addition, to ensure operational continuity, especially at night or when exposure to sunlight is low, energy storage capacity in the form of batteries of 230 kWh is required so that the cold storage can function without interruption. The results of this research show that with proper planning, the use of renewable energy through solar power can be optimized to support the sustainability of cold storage operations, even in environments with significant energy availability challenges. This research makes an important contribution to the development of efficient and sustainable portable cold storage technology

Abstract

This study focuses on the design and development of a smoking device aimed at enhancing the quality and production efficiency of smoked fish. The primary objective was to create a device that optimizes the smoking process, ensuring consistent product quality while increasing production capacity. The development process involved a systematic design approach, including the selection of materials and construction techniques. The smoking process utilized a combination of drying and the application of natural smoke compounds derived from the combustion of organic materials. Performance testing was conducted using catfish as the primary substrate, with measurements taken for smoking duration, moisture content, and production rate. The effectiveness of the device was evaluated based on sensory characteristics, including texture, color, and aroma. The smoking apparatus was constructed with dimensions of 126 cm x 100 cm x 180 cm and is capable of accommodating up to 32 kg of fresh fish per smoking cycle. Results indicated that the smoking device achieves a production rate of 4 kg of smoked fish per hour, yielding products with a desirable golden-brown color and distinct smoky aroma. The findings demonstrate that the device significantly improves production capacity and allows for enhanced control over smoking conditions, contributing to greater consistency in product quality.
