This study was conducted to estimate the company's optimal profit by considering the product supply chain in a company that receives orders from several distributors. If all orders cannot be fulfilled by the available production capacity, the company will offer a solution in allocating capacity to distributors by considering scheduling costs and other constraints. The main work in estimating the company's profit is modeling the scheduling costs and constraints in the capacity allocation problem in the company. That is, the company makes order scheduling to minimize costs to achieve maximum profit by applying the Karush-Kuhn-Tucker (KKT) method. Karush-Khun-Tucker can be used to find the optimal solution of the function formed from the allocation and scheduling problems whether linear or nonlinear. In the process, the KKT method basically involves the same steps as the Lagrange method to be able to calculate the critical point and find the optimum solution. It is suggested for further research to involve more varied variables with more interesting cases.

Assignment problem is one part of linear programming that can be found in real life. The Assignment problem includes m workers who have n tasks assuming n=m. The division of work is seriously handled by the company so that each employee gets an equal amount of work hours that are determined. This study aims to optimize employee assignments based on minimum operational costs and minimum job completion times using the Hungarian method. Optimization is a mathematical approach that deals with maximum and minimum problems. From the results of the study, after using the Hungarian method, the work completion time on the Kefamenanu Supermarket Metro was 9: 34: 20 (in hours, minutes, seconds). The total operational costs of work incurred by the company if calculated using the Hungarian method with MATLAB software, the results are Rp. 11,141. Furthermore, the order of minimization of employee assignments is obtained as follows: II, VII, I, IV, VI, V and III.

The activity of filling in school data, student data, and student final grades in report card at elementary schools in the Insana Fafinesu District, Timor Tengah Utara Regency has been carried out in handwriting (conventional), which have some constraints such as taking a long time to processing grades, has a tendency to miscalculation if the student report card is lost or damaged, it does not have documentation/ back-up documents. For teachers who have sloppy handwriting, it will be difficult for a parent to read. One software that can be used in making student report cards is Microsoft Office Excel. This software is easy to understand and can overcome problems in making student report cards such as the length of time for processing grades, the tendency of grade processing error, difficulties in reading teacher writing by parents, and overcoming problems with documentation/backup documents. This service activity aims to provide training in making e-report card applications using Microsoft Excel for elementary school teachers in the Insana Fafinesu area, Timor Tengah Utara Regency. The methods used in this activity are workshops and ongoing mentoring. As a result, teachers better understand the functions in Microsoft Excel that are useful in the process of filling out student report cards, each teacher succeeds in making their own e-reports, and they agree that e-reports with Microsoft Excel are more efficient and effective than filling out report cards manually (conventional) and will use e-reports in their respective schools. The next plan for this service activity will be an application for Teacher Performance Assessment (TPA) and Employee Work Targets (EWT).

Based on the slope class, the shape of the area and the elevation of dry land in Nusa Tenggara, agricultural land in Noepesu Village is suitable for planting coffee plants with an agroforestry scheme. To overcome the problem of limited water, drip irrigation system technology can be applied. The use of drip irrigation as an agricultural technology in Noepesu village has been carried out by many farmer groups. Still, the installation process does not consider the pipe specifications (pipe length and pipe diameter) and the condition of agricultural land. This causes the service life of drip irrigation to be not long. If this continues, of course, it will increase system installation costs. To optimize service life, a hydraulics analysis method is needed for drip irrigation pipe network systems that take into account pipe specifications and agricultural land conditions.The hydraulics analysis of the drip irrigation network system determines the emitter’s water flow rate. The emitter flow rate forms a nonlinear equation known as the closed pipe equation. In the process of solving these equations, numerical methods can be used, specifically the Newton-Raphson method. This study focuses on applying the Newton-Raphson method to calculate the amount of water discharge from each emitter of the drip irrigation network system on the farmland of the Mutis Cemerlang Farmer Group in Noepesu Village. The drip irrigation system is designed with 250 nodes, 275 pipes, 26 loops, and 86 outlets divided into two sides, with the left side containing 84 outlets with one emitter and the right side containing 102 outlets with two emitters. The amount of water discharge for each emitter is 0,0008 ml/second≤Q≤2,6 ml/second for the left side and 0,001 ml/second≤Q≤1,1 ml/second for the right side, as determined by simulation calculations utilizing the Newton-Raphson method and Matlab software. The simulation results show that the amount of water discharge at each emitter is ideal in the first iteration because it has a discharge correction value (∆Q)≈0.
