Concrete is the main basic material used for planning and designing building structures and is widely used as a building material. One of the efforts to improve the unfavorable properties of the concrete in this case is to add bendrat wire fiber to the concrete mix. In this study, bendrat wire fibers in the shape of "U" and "Z" were used with variations in the addition of fiber in the concrete mix of 0.5%, 0.75% and 1% of the cement weight. The bendrat wire used has a length of 60 mm and a diameter of 1 mm. The test specimens were made in the form of a double-L beam with dimensions (200 x 150 x 300) mm as many as 21 pieces. Double-L beam testing was carried out at the age of 28 days using a Compression Testing Machine (CTM). From the results of the research, the highest shear strength of concrete was obtained in "U" shape bentrat wire fiber concrete with 1% bendrat wire percentage (BF3) with an average value of 6.00 MPa or an increase in concrete shear strength of 46.33% compared to Normal Concrete (BN). The value of the shear strength of the double-L beam with "U" shape bendrat wire fiber is higher than the value of the double-L shear strength beam with "Z" shape bendrat wire fiber although the difference in the shear strength value is not too significant. The addition of "U" and "Z" bentrat wire fibers can reduce cracks in the concrete.
混凝土是用于建筑结构规划设计的主要基础材料，是一种用途广泛的建筑材料。在这种情况下，改善混凝土不利性能的努力之一是在混凝土配合比中加入弯曲丝纤维。在本研究中，采用“U”形和“Z”形的弯曲钢丝纤维，纤维在混凝土配合比中的添加量分别为水泥重量的0.5%、0.75%和1%。使用的弯线长度为60mm，直径为1mm。试件以双l梁的形式制作，尺寸为(200 x 150 x 300) mm，多达21块。28日龄用压缩试验机(CTM)进行双l梁试验。研究结果表明，当弯丝率(BF3)为1%时，“U”形弯丝纤维混凝土抗剪强度最高，平均为6.00 MPa，比普通混凝土(BN)抗剪强度提高46.33%。采用“U”形弯丝纤维的双l梁抗剪强度值高于采用“Z”形弯丝纤维的双l梁抗剪强度值，但差异不太显著。“U”型和“Z”型弯丝纤维的加入可以减少混凝土中的裂缝。

STMIK Lombok is one of the Private Universities that regularly conduct assessments of lecturers every semester. This is done in order to motivate lecturers in improving service to students. Although in its implementation, the performance assessment of this lecturer runs smoothly but has not reached optimal because it still uses Microsoft Excel in the calculation process so it takes a long time in the process of calculating values and reporting process. so it still needs improvements, especially in the assessment process using the application. This research aims to build an assessment information system and evaluate the performance of STMIK Lombok lecturers. The ARAS (Additive Ratio Assessment) method is one of the multicryteria decision-making methods based on the concept of combat using a utility degree, namely by comparing the overall index value of each alternatife to the optimal alternative overall index value. This decision support system can provide selected alternative decisions that can later be used as a reference to determine the best Lecturer Performance. The system development method used is Waterfall, PHP as a programming language and uses data flow diagram (DFD) system modeling. The testing process used in this application is the Black Box. The results of this built Application can speed up the process of calculating the performance assessment of lecturers and the reporting process more effectively and efficiently.
STMIK龙目岛是一所私立大学，每学期定期对讲师进行评估。这样做是为了激励讲师改善对学生的服务。该讲师的绩效考核虽然在实施过程中运行顺利，但由于其在计算过程中仍然使用Microsoft Excel，因此在计算数值和报告过程中花费的时间较长，因此没有达到最优。因此，它仍然需要改进，特别是在使用应用程序的评估过程中。本研究旨在建立一个评估资讯系统，并评估龙目岛学院讲师的表现。ARAS (Additive Ratio Assessment)方法是一种基于效用度作战概念的多条件决策方法，即将各备选方案的综合指标值与最优备选方案的综合指标值进行比较。这个决策支持系统可以提供选择的备选决策，这些决策以后可以用作确定最佳讲师表现的参考。系统采用瀑布式开发方法，以PHP为编程语言，采用数据流图(DFD)系统建模。此应用程序中使用的测试过程是黑盒。该应用程序的结果可以加快教师绩效评估的计算过程和报告过程，更加有效和高效。

Indonesia is the confluence of three of the world's major plates, therefore a lot of plate activity occurs so that earthquake intensity often occurs. The earthquake resulted in many casualties, this is because many building structures do not meet the requirements of earthquake-resistant buildings. The structure of mosque buildings in Lombok has many towering mosque towers. Many mosque buildings in Lombok do not apply the earthquake-resistant building principle, namely strong column weak beam, so that the average mosque building collapses is the soft story type. The research method used to optimize the dimensions of the columnar beam in this study there are two methods, namely optimization using SAP 2000 and then optimization using Artificial Neural Network (ANN) modeling. The empirical equations obtained are three equations, namely the equation of a beam, a square column and a circle column. The percentage of error that occurs in the use of the empirical formula is 0.88%, so that the equation can be used to perform dimensional prediction calculations with different variations.

The planning and design of a Hotel & Resort should be in accordance with the climate and location of the construction. In Indonesia, especially in areas that have cool air and are far from air pollution and noise pollution, they have a tropical climate, so Tropical Architecture is very suitable for planning and designing Hotels & Resorts, but it is possible to plan and design Hotels & Resorts with other architectural characteristics. Modeling studies can also be called modeling design and information about buildings, which is a field of science that examines development planning, development implementation, and maintaining and repairing if there is damage in a building. Activities from these fields of science are studying design drawings of houses, offices, buildings, and so on. In addition, this field of science does not only study building design, but this field of science will learn how to calculate the cost budget plan which is often referred to as RAB. Air circulation modeling has several sub-specifics, namely Planning Plan, building view, section view, Air Flow Scheme, and air circulation calculation. The building modeling method here uses an application called Autocad and SketchUp, then for the calculation of the natural air circulation using the ACPH (Hourly Air Exchange System) method. . Building 1 has a building area of approximately 1486.7 M2 2 floors, building 2 has a building area of 461 M2 1 floor, and the hotel room area has a building area of 940.56 M2.

Concrete is the main basic material used for the planning and design of widely used structures. This is because concrete has a very high compressive strength value when compared to other materials. However, concrete also has weaknesses, one of which is its brittle nature. Therefore, in this study, the use of Z-shaped bendrat wire will be carried out to increase the value of the compressive strength of concrete while improving the brittle nature of the concrete.In this study, bendrat wire fiber in the form of Z was used with a mixed variation of 0.5%, 0.75% and 1%. The number of test objects made is 12 pieces. The test was carried out when the specimen was 28 days old by using a Compression Testing Machine (CTM). From the results of the study, the average compressive strength value for normal concrete (SN) was 26.46 MPa, for Z-shaped bendrat wire fiber concrete with a mixed variation of 0.5% (SF1) the average compressive strength value was 27.27 MPa, for fiber concrete bendrat wire Z shape with a mixed variation of 0.75% (SF2) the average compressive strength value is 28.03 MPa, and for fiber concrete wire bendrat Z shape with a mixed variation of 1% (SF3) the average compressive strength value is 28.21 MPa. The more Z-shaped bendrat wire fibers added to the concrete mix, the higher the compressive strength value and the smaller the cracks that occur in the concrete.

Therefore, in this study, the use of Z-shaped bendrat wire will be carried out to increase the value of the compressive strength of concrete while improving the brittle nature of the concrete.In this study, bendrat wire fiber in the form of Z was used with a mixed variation of 0.5%, 0.75% and 1%. The number of test objects made is 12 pieces. The test was carried out when the specimen was 28 days old by using a Compression Testing Machine (CTM). From the results of the study, the average compressive strength value for normal concrete (SN) was 26.46 MPa, for Z-shaped bendrat wire fiber concrete with a mixed variation of 0.5% (SF1) the average compressive strength value was 27.27 MPa, for fiber concrete bendrat wire Z shape with a mixed variation of 0.75% (SF2) the average compressive strength value is 28.03 MPa, and for fiber concrete wire bendrat Z shape with a mixed variation of 1% (SF3) the average compressive strength value is 28.21 MPa. The more Z-shaped bendrat wire fibers added to the concrete mix, the higher the compressive strength value and the smaller the cracks that occur in the concrete.","PeriodicalId":448230,"journal":{"name":"J-ENSITEC","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-01-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127166039","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

So far, the drying process carried out by farmers is still simple, namely by drying it directly in the sun. This method is less effective because it will require a large area with a relatively long drying time of 10-12 days. The author will conduct research on the design and testing of a red chili drying machine using Solidwork software. The drying process used in this red chili drying machine uses a tubular heater. It is hoped that the design of this red chili drying machine can increase the production of dry red chilies. The results of the research show that the chili drying machine is designed into 2 parts that are bulkhead using a filter with dimensions of 385 x 320 mm, the dimensions of the drying room are 400 mm long, 421 mm wide, 353 mm high, in the drying room section there are 10 shelves that can be assembled and assembled. with dimensions of 400 x 380 mm for storing chilies to be dried and the dimensions of the combustion chamber having dimensions of 140 mm in length, 421 mm in width and 353 mm in height, then the tool will be made of stainless steel sheet with a thickness of 3 mm. / fan with a diameter of 170 mm which has 5 propeller blades, and the fan is rotated using an electric motor type yj62-25 with a voltage of 100-240 VAC, a frequency of 50/60 HZ and a power of 5-100W.
到目前为止，农民进行的干燥过程仍然很简单，即直接在阳光下干燥。这种方法效果较差，因为它需要很大的面积和相对较长的干燥时间，为10-12天。本文将利用Solidwork软件对一台红辣椒干燥机进行设计与测试研究。本红辣椒干燥机的干燥过程采用管状加热器。希望本设计能够增加干辣椒的产量。研究结果表明，辣椒干燥机设计成2部分，隔板采用尺寸为385 × 320 mm的过滤器，干燥室尺寸为长400 mm，宽421 mm，高353 mm，干燥室部分有10个可拼装的货架。尺寸为400 x 380毫米储存辣椒干,燃烧室有维度的尺寸长度140毫米,宽421毫米和353毫米高,那么该工具将由不锈钢薄板的厚度3毫米。/风扇直径170 mm 5螺旋桨叶片,并使用一个电动马达风扇旋转类型yj62-25 100 - 240伏的电压,频率50/60 HZ和5 - 100 w的力量。
