Abstract

Moringa trees are often planted as living fences and along rice fields or paddy fields, and they also function as green plants. In addition, Moringa leaves are also known as an efficacious medicinal plant by utilizing all parts of the Moringa plant, starting from the bark, seeds, and leaves to the roots and undergoing processing operations such as drying, wilting and enzymatic oxidation. The processing of Moringa goes is carried out with a drying process that aims to speed up the processing of Moringa leaves. Tests on drying Moringa leaves are carried out in 2 ways, namely drying without using controls and drying using fuzzy rules, then, from the two tests, a comparison will be made, and conclusions will be drawn. This drying was carried out to determine how much weight loss was in dried Moringa leaves using fuzzy control with a temperature of 60 °C. The overall test results for Moringa leaves were carried out with two tests. Namely, the same results will be obtained from 180-gram Moringa leaves at 60°C and 180-gram Moringa leaves at 50°C. Temperature and time with a decrease in the percentage of age by 50% using fuzzy control. This system is supported by a type k thermocouple temperature sensor, load cell sensor, tubular heater, fan, solid state relay, keypad, I2C LCD, and Arduino mega. Two input variables must be controlled in a fish dryer: temperature and weight. At variable temperatures, the input is a type k thermocouple sensor. The output is an SSR that controls the tube heater so that the temperature of the fish dryer matches the set-point temperature. The fuzzy logic method controls the temperature when drying fish does not exceed the set point temperature.

Abstract

The distribution network is an integral part of electricity distribution, both technically and non-technically, which is very vulnerable to disturbances. This disturbance should be resolved as soon as possible so that it does not interfere with the performance of the electricity distribution and also damage the distribution transformer. In overcoming this disturbance, it can be done by using a safety device and a voltage breaker in each load area. The protection system in the distribution network must work quickly and immediately isolate abnormal conditions to prevent further damage and minimize blackouts. This disturbance should be resolved as soon as possible so that it does not interfere with the performance of the electricity distribution and also damage the distribution transformer. . The effects of this disturbance are changed in voltage, current, temperature, and gas levels in the distribution transformer. So we need a tool that can monitor the condition of the transformer. NodeMCU ESP8266 is a microcontroller that can connect to the internet network, which is used as the central control. The PZEEM-004T sensor is applied as a current and voltage reader. For gas measurement, the MQ-4 sensor is used to measure CH4 gas levels; the MQ-7 sensor is used to measure CO gas levels, and the MQ-8 sensor is used to measure H2 gas levels. The test results found that due to the unbalanced load conditions, there was an increase in temperature in the transformer, which resulted in changes in gas levels. Where from the test, it was found that the lowest gas content was CH4 reaching 113 PPM, CO went 21PPM, and H2 reaching 158PPM.

Abstract

Kuala Bubon Port, a maritime axis in the west-south Aceh region is one of the crossing facilities that connects shipping activities by the surrounding community. The need for passenger departures and logistics transportation is increasing every year. Therefore, to facilitate inter-island crossing activities, it is planned to develop buildings and facilities at Kuala Bubon Port. It is necessary to carry out a feasibility study for these infrastructure development activities to determine the feasibility of the development project. Besides that, the feasibility study also avoids the risk of loss. Research This feasibility study uses data analysis, including the Budget Plan analysis and the cash flow (cash flow) analysis. The method for analyzing cash flow uses 4 methods, namely Net Present Value (NPV), Benefit Cost Ratio (BCR), Internal Rate of Return (IRR), and Break Event Point (BEP). The four methods refer to the calculation of direct, indirect, and annual costs. This calculation is obtained from processing primary and secondary data and assuming an interest rate of 3.50%, and the project's economic life is set at 25 years. For NPV analysis, the investment is feasible if the results are positive. Conversely, if the NPV is negative, the investment is not feasible. Furthermore, if the BCR value ≥ 1, the IRR value ≥ the interest rate, and the BEP are obtained when the NPV = 0, then the project can be feasible. After calculating, the NPV value obtained is IDR 1,730,821,838,222, the BCR value is 162.93%, the IRR value is 5.25%, and the BEP was obtained in year 4, day 39. Based on the results of these calculations, the project can be said to be feasible to implement. The results of this study are expected to be one of the references and information for the Department of Transportation, Water Resources Public Works, and the Government to plan the right design for development projects at ports. The long-term target is that the results obtained can be used as data in other water construction projects so that they are effective from a financial perspective.

Abstract

Groundnut shell powder contains significant amounts of the chemical silica (SiO) to be utilized as construction materials. Through the use of groundnut shell powder, this study seeks to determine the split tensile strength of concrete (GSP). With a compressive strength design of f'c =21.7 MPa, the concrete mixture adheres to ACI 2I1.1-91. The aggregate of crushed stone with a maximum diameter of 19.1 mm. Portland cement type I is the type of cement utilized. With a variation of 0%, 5%, 7,5%, 10%, and 12.5%, additional material (GSP) substitutes cement in part. At 14 and 28 days old, concrete is tested for its tensile strength. For each modification, there are three cylindrical test objects, each measuring 30 cm in length and 15 cm in diameter. The split tensile strength of concrete was tested using 14-day-old peanut shell powder, and the results were 1,699 MPa, 1,840 MPa, 1,581 MPa, and 1,510 MPa, respectively. The findings demonstrated that concrete's split tensile strength (f'ct) was 28 days with a fluctuation of 0%; 5%; 7,5%; 10%; and the sequential 12.5% was 1,934; 2,170; 2.265; 1,958; and 1,887 Mpa. Following the findings, the ideal tensile strength value was at a variation of 7.5%, or 2,265 MPa, greater than 0% (1,934 MPa) of 17.11%. The age of 28 days was 7.5% higher than the age of 14 days (1,840 MPa) of 23.10% for the variation's maximum tensile strength. Compared to standard compressive strength test findings, the Split tensile strength value of concrete utilizing GSP is 6.83%

Abstract

An investigation into the performance of the building structure in receiving the earthquake load must ensure that the building structure is able to receive it within safe limits. A non-linear approach is generally done through pushover analysis. The purpose of this study is to find out how the behavior or performance of building structures when receiving earthquake loads. The analysis is carried out by modeling the structure of the building using the help of the STERA 3D application. Then it is done by entering the Kobe earthquake spectrum data into the software. From the results of the analysis, the value of the deviation between directional levels X 0.0058 m with a base shear of 10,090 KN was obtained. While the Y direction capacity curve has the largest displacement of 0.0084 m with a base shear of 13,270 KN. The result of structural deviation when the performance point is reached for X direction and Y direction loading of 0.0042 m and 0.0063 m, resulting in a yellow color at each point of the column and beam relationship which means that it is still within the range of 1 U 5 (AMP (response force) analysis), this indicates that the condition of the building structure remains safe during an earthquake.

Abstract

Shellfish (bivalves) are potential biodiversity of waters with an important significant value used by the community as a food source of highly nutritious animal protein. Based on survey results, several coastal areas in North Aceh District have the potential for shellfish. Still, there have not been any scientific reports on this region's proximate composition of bivalves. This study aims to determine the relative arrangement of the dominant bivalves in the North Aceh District based on species differences and environmental characteristics. The results showed varying proximate bivalve proximate compositions of 4 chief types of shellfish in North Aceh waters. Bivalvia water ranged from 6.9-14.2%, ash ranged from 5.87-8.29%, protein ranged from 32.84-35.87%, fat ranged from 3.04-10.83%, and carbohydrate ranged from 38.11-42.71%. The highest protein and fat content were found in the Crassostrea sp1 type clams. In addition, the differences in the environmental characteristics of the shell sampling locations also resulted in different proximate compositions. The PCA test results showed that the critical variablarrangemente composition was ash and fat content. The environmental parameters, which were the key parameters of the relative arrangement of the shells were the substrate and pH.
