Soft crab is an export product where foreign demand is much higher than production. In the production of soft crabs, it is done by keeping the crabs individually in a crab box which is placed in the pond until they molt. Molting is a natural process of molting, i.e. removing the old tough skin for growth purposes. Shortly after molting, the new crab shells are still very soft and will harden again after water absorption occurs. Therefore it is important to monitor molting crabs to help farmers in the cultivation of soft shell crabs. The number of crab datasets is 1060 which consists of 1000 training data and 60 testing data. There are several popular image classification algorithms, namely K-Nearest Neighbors (KNN), Support Vector Machine (SVM), and Random Forest Classifier (RFC). KNN, SVM, and RFC are classification algorithms from Machine Learning. This study aims to compare the performance of the three algorithms so that the performance of the three algorithms is known. Several parameters are used to configure the KNN, SVM, and RFC algorithms. From the results of the trials conducted, KNN has the best performance with 98.33% accuracy, 98.33% precision, 98.38% recall, and 98.38% F1 Score.

Planning and controlling costs and time is part of the overall construction project management. In addition to the assessment in terms of quality, the achievement of a project can also be assessed in terms of cost and time. The costs that have been incurred and the time spent in completing a job must be measured continuously for deviations from the plan. The presence of significant cost and time deviations indicates poor project management. With the existence of project performance indicators in terms of cost and time this allows preventive actions so that project implementation goes according to plan. The concept of "Earned Value" is one of the tools used in project management that integrates cost and time and by using Ms. Projects. Ms. Project is a project management software product and is developed and sold by Microsoft. It is designed to assist a project manager in developing plans, assigning resources and tasks, tracking progress, managing budgets and analyzing workloads. From the results of the evaluation of cost control and project schedules on outpatient and basement building construction projects using the earned value method, it can be concluded that the CV (Cost Variant) in this project results in 0 which means the Zero Number on the Cost Variant indicates that the cost is within the budget, SV (Schedule). Variant ) the value shows a negative number, this means that the completion of the work is delayed, the CPI (Cost Performance Index) is 1, meaning that the expenditure is in accordance with the project budget

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.

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.

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 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.

To increase the allocation of water in the river basin (WS) of southern Lombok, the potential for irrigation areas (AI) has spread widely, since the 1980s, efforts have been made to transfer water from wet river basins to dry watersheds. The transfer is through the Babak-Renggung-Rutus High Level Diversion (HLD) channel (18 km) and the Jangkok-Babak-Jurang Sate channel (43 km), as well as 22 other channeling channels in / across the watershed (87 km). Until now, 12 watersheds are connected, namely: Meninting, Jangkok, Remening, Babak, Dodokan, Renggung, Pare, Rere, Palung, Moyot, Aikampat and Starfruit. The number of main structures for taking water (headwork or HW) in the watersheds include 3 dams (BD), 77 reservoirs (E), 355 dams (B), and 55 diversions in the Jangkok-Babak-Jurang Sate canal. A total of 487 HWs were intended to irrigate 98,878 ha of irrigated land in 432 Irrigation Areas (DI) and a little to supply raw water of 404 l / sec. In addition, there are 2442 l / sec raw water withdrawals directly from 42 points of springs which are spread in the watershed: Jangkok, Babak, Aikampat, Meninting Midang, Kelongkong Remening, Renggung, Rung and Starfruit. Analysis of reservoir operational performance using the Hashimoto method yields a coefficient of Reliability (R) = 100%, Resiliency (R) = 100%, and Vulnerability (V) = 0%. So based on this RRV value the reservoir operational performance is categorized as maximum sustainable
