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.
贝类(双壳类)是潜在的水域生物多样性,具有重要的重要价值,被社区用作高营养动物蛋白的食物来源。根据调查结果,北亚齐地区的几个沿海地区具有贝类的潜力。然而,关于这个地区双壳类动物的大致组成,还没有任何科学报告。本研究旨在根据物种差异和环境特征确定北亚齐地区优势双壳类的相对分布。结果表明,亚齐北部水域4种主要贝类的近双壳类近组成存在差异。双壳壳水分含量为6.9 ~ 14.2%,灰分含量为5.87 ~ 8.29%,蛋白质含量为32.84 ~ 35.87%,脂肪含量为3.04 ~ 10.83%,碳水化合物含量为38.11 ~ 42.71%。其中蛋白质和脂肪含量最高的是长牡蛎sp1型。此外,贝壳取样地点环境特征的差异也导致了近似值组成的不同。主成分分析结果表明,关键变量为灰分和脂肪含量。底物和pH是影响壳相对排列的关键环境参数。

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%
花生壳粉末含有大量的化学二氧化硅(SiO),可以用作建筑材料。通过花生壳粉的使用,本研究试图确定混凝土的劈裂抗拉强度(GSP)。抗压强度设计f′c =21.7 MPa,符合ACI 2I1.1-91标准。碎石骨料,最大直径19.1 mm。I型硅酸盐水泥是所使用的水泥类型。在0%、5%、7%、5%、10%和12.5%的变化范围内,附加材料(GSP)部分替代水泥。在14天和28天,测试混凝土的抗拉强度。每次修改都有三个圆柱形测试对象,每个测试对象的长度为30厘米,直径为15厘米。采用14日龄花生壳粉对混凝土进行劈裂抗拉强度测试,结果分别为1699 MPa、1840 MPa、1581 MPa和1510 MPa。结果表明:混凝土劈裂抗拉强度f'ct为28 d,波动幅度为0%;5%;7, 5%;10%;12.5%的顺序是1934;2170;2.265;1958;1887兆帕。结果表明,理想抗拉强度值变化幅度为7.5% (2265 MPa),大于0% (1934 MPa)的17.11%。28 d龄期的最大抗拉强度比14 d龄期(1840 MPa)的最大抗拉强度提高了7.5%,提高了23.10%。与标准抗压强度试验结果相比,使用GSP的混凝土劈裂抗拉强度值为6.83%

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.

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.
吉隆坡布本港是亚齐西南地区的海上轴心,是连接周边社区航运活动的过境设施之一。旅客离港和物流运输的需求每年都在增加。因此,为了方便跨岛活动,计划在吉隆坡港发展建筑物和设施。有必要对这些基础设施发展活动进行可行性研究,以确定发展项目的可行性。除此之外,可行性研究也避免了损失的风险。本可行性研究使用数据分析,包括预算计划分析和现金流量(现金流)分析。现金流量的分析方法采用净现值法(NPV)、效益成本比法(BCR)、内部收益率法(IRR)和突发事件点法(BEP)四种方法。这四种方法是指直接成本、间接成本和年成本的计算。该计算是通过对一手资料和二次资料进行处理,假设利率为3.50%,项目经济寿命设定为25年。对于NPV分析,如果结果为正,则投资是可行的。相反,如果NPV为负,则投资是不可行的。如果BCR值≥1,IRR值≥利率,且NPV = 0时获得BEP,则该项目是可行的。计算得到净现值为1730,821,838,222印尼盾,BCR值为162.93%,IRR值为5.25%,净收益为第4年第39天。根据这些计算结果,可以说该项目是可行的。本研究结果可作为交通部、水利部、公共工程部及政府在规划港口发展项目设计时的参考资料之一。长期目标是获得的结果可以作为其他水利建设项目的数据,使其从财务角度来看是有效的。

Aggregate gradation is measured by determining the percentage of various particle sizes in an aggregate sample using a standard sieve arrangement. Gradation is usually expressed as a curve showing the percentage of each particle size on a logarithmic scale. This curve can then be used to determine the optimum mix design for a given concrete grade. The purpose of this research is to determine the effect of adjusting the gradation of the coarse aggregate of crushed clinker bricks on the strength of concrete. Clinkers bricks are bricks that have been burned at temperatures that are excessively high. The coarse aggregate grading is adjusted according to aggregate grading limits based on SNI 7656-2012, which are divided into three types of grading limits, namely upper, middle, and lower limits. A total of 60 cylindrical 150mm x 300mm concrete specimens were used for the compressive strength tests. The findings showed that adjusting the lower limit gradation produced optimum compressive strengths of 29.09 MPa, 35.08 MPa, 39.96 MPa, and 38.82 MPa, respectively, for the specified target concrete strengths of 20 MPa, 25 MPa, 30 MPa, and 35 MPa, which were higher than those of the middle and upper limit gradations. The compressive strength and density of the concrete can be significantly improved by modification of the coarse aggregate grading of the clinker bricks
骨料级配是通过使用标准筛子排列确定骨料样品中各种粒径的百分比来测量的。级配通常用曲线表示,在对数尺度上表示每种粒度的百分比。该曲线可用于确定给定混凝土等级的最佳配合比设计。本研究的目的是确定调整熟料砖粗集料级配对混凝土强度的影响。熟料砖是在过高温度下燃烧的砖。粗骨料级配根据SNI 7656-2012骨料级配限值进行调整。SNI 7656-2012骨料级配限值分为上、中、下限三种级配限值。共使用60个150mm × 300mm圆柱形混凝土试件进行抗压强度试验。结果表明:当混凝土强度为20 MPa、25 MPa、30 MPa、35 MPa时,调整下限级配可产生的最佳抗压强度分别为29.09 MPa、35.08 MPa、39.96 MPa、38.82 MPa,均高于中、上限级配;通过对熟料砖的粗骨料级配进行改性,可以显著提高混凝土的抗压强度和密度

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.
辣木树通常作为活栅栏种植,沿着稻田或水田种植,它们也有绿色植物的功能。此外,辣木叶也是一种有效的药用植物,利用了辣木植物的所有部分,从树皮、种子、叶子到根,经过干燥、枯萎和酶氧化等加工操作。辣木果的加工是通过干燥过程进行的,旨在加快辣木叶的加工速度。采用无控制干燥和模糊规则干燥两种方法对辣木叶进行干燥试验,并对两种方法进行比较,得出结论。在温度为60°C的条件下,采用模糊控制进行干燥,以确定干燥后辣木叶的失重程度。对辣木叶的总体试验结果进行了两次试验。也就是说,180克的辣木叶在60°C和180克的辣木叶在50°C下得到相同的结果。采用模糊控制,温度和时间随龄期百分比下降50%。该系统由k型热电偶温度传感器,称重传感器,管状加热器,风扇,固态继电器,键盘,I2C LCD和Arduino mega支持。在鱼干机中必须控制两个输入变量:温度和重量。在可变温度下,输入是k型热电偶传感器。输出是一个SSR,控制管加热器,使鱼烘干机的温度匹配设定点温度。模糊逻辑方法控制干燥鱼不超过设定值温度时的温度。

Fish is a food in great demand at home and abroad, and apart from its delicious taste, fish is also prevalent because of its health benefits. High protein content and lower fat content compared to other animal protein sources. However, the quality of fish is effortless to decline and spoil. One of the efforts to preserve processed fish so that it can be stored for a more extended period is using preservation. The purpose of preserving fish is to keep fish as long as possible by eliminating the causes of spoilage. There are various types of fish preservation, one of which is drying. Fish drying is a process of reducing the water content in fish to inhibit spoilage. Several factors affect the drying fish’s operation: temperature and airflow velocity. Temperatures that are too large can cause case hardening where the outside of the fish is dry, but the inside is still wet. Then the temperature chosen in this study was 50°C and 60°C with consideration of nutritional standards for dried fish and airflow velocity of 1.5 - 2 m/s. According to SNI 2732.3: 2009, the maximum water content in dried fish is 40%. 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 holds the tube heater so that the temperature of the fish dryer matches the setpoint temperature. The fuzzy logic method controls the temperature when drying fish does not exceed the set point temperature.
鱼在国内外都是一种需求量很大的食物,除了味道鲜美之外,鱼还因其有益健康而广受欢迎。与其他动物蛋白来源相比,蛋白质含量高,脂肪含量低。然而,鱼的品质很容易下降和变质。为了保存加工过的鱼,使其可以保存更长的时间,其中一项努力就是使用保鲜法。保存鱼的目的是通过消除导致变质的原因,使鱼尽可能长时间地保存。鱼的保存方法有很多种,其中一种就是干燥。鱼的干燥是减少鱼的含水量,以防止变质的过程。有几个因素影响干燥鱼的操作:温度和气流速度。温度太高会导致鱼的表面变硬,鱼的内部是湿的,但外面是干的。然后考虑鱼干的营养标准,本研究选择的温度分别为50℃和60℃,风速为1.5 ~ 2m /s。根据SNI 2732.3: 2009,干鱼的最大含水量为40%。该系统由k型热电偶温度传感器,称重传感器,管状加热器,风扇,固态继电器,键盘,I2C LCD和Arduino mega支持。在鱼干机中必须控制两个输入变量:温度和重量。在可变温度下,输入是k型热电偶传感器。输出是一个SSR,保持管加热器,使鱼烘干机的温度匹配设定值温度。模糊逻辑方法控制干燥鱼不超过设定值温度时的温度。

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.
配电网在技术上和非技术上都是配电系统的重要组成部分,非常容易受到干扰。这种干扰应尽快解决,以免影响配电的性能,损坏配电变压器。为了克服这种干扰,可以在每个负载区使用安全装置和电压断路器。配电网中的保护系统必须快速工作并立即隔离异常情况,以防止进一步的损害并尽量减少停电。这种干扰应尽快解决,以免影响配电的正常运行,损坏配电变压器。这种扰动的影响改变了配电变压器中的电压、电流、温度和气体水平。因此,我们需要一种能够监测变压器状态的工具。NodeMCU ESP8266是一款可以连接到internet网络的微控制器,作为中央控制。PZEEM-004T传感器用作电流和电压读取器。对于气体测量,MQ-4传感器用于测量CH4气体水平;MQ-7传感器用于测量CO气体浓度,MQ-8传感器用于测量H2气体浓度。测试结果发现,由于负载不平衡,变压器内温度升高,导致气体水平变化。从试验中发现,最低气体含量为CH4达到113 PPM, CO达到21PPM, H2达到158PPM。
