Abstract

Metode konjugat gradien merupakan suatu metode untuk menyelesaikan sistem persamaan linier pada skala besar, yang mana metode tersebut diperkenalkan oleh Hestenes dan Stiefel untuk menyelesaikan permasalahan tersebut. Metode konjugat gradien merupakan metode iteratif dan juga merupakan salah satu metode yang efektif dalam menyelesaikan optimasi tak berkendala. Dalam tulisan ini, penulis melakukan pengusulan metode konjugat gradien hibrid baru berdasarkan ide dari metode NH1, NH2, NH3 dan NH4. Metode hibrid tersebut diusulkan berdasarkan dari kekurangan dan kelebihan dari metode sebelumnya yaitu metode HS, FR, PRP, CD, LS dan Metode DY. Kekurangan dan kelebihan dari metode-metode tersebut diantaranya proses kinerja komputasi (iterasi) kurang baik dan kekonvergenan global. Berdasarkan dari metode-metode hibrid yang diusulkan tersebut maka penulis mengusulkan metode baru yaitu penggabungan dari metode LS dengan metode DY, dimana metode LS memiliki kelebihan pada kinerja komputasi dan DY kelebihannya pada kekonvergenan globalnya. Metode hibrid baru yang diusulkan tersebut yaitu metode NH5 (LS-DY) dan metode yang diusulkan ini akan di ujikan pada fungsi tak linear orde tinggi. Metode baru menunjukkan bahwa fungsi-fungsi yang diberikan dapat diselesaikan dengan sangat efisien serta perbandingan metode NH5 dengan metode-metode sebelumnya menunjukkan hasil pada proses komputasinya baik dan dapat bersaingKata Kunci: metode konjugat gradien, metode hibrid, knerja komputasi.

Abstract

Potential for the development of the mangrove crab business in the coastal area of the city of Langsa, which has a fairly large mangrove forest area and produces abundant mangrove crab resources. However, some of the results of the study stated that the exploitation and the absence of restrictions on the size of the capture of mangrove crabs resulted in a decrease in the number of catchments by fishermen because the condition of crab stock in nature has decreased. The purpose of dedication is to provide education and training to fishermen about selling mangrove crabs, which is more prioritized than fattening results from direct catches from nature, and to increase the production of mud crabs by utilizing local materials. The next goal is the management of crab capture. Implementation of dedication is carried out through socialization and training for coastal communities and fishermen in Sungai Pauh Tanjung Village, Langsa City. The results of the implementation of community service activities contribute to increasing skills and added value, as well as increasing the production of mangrove crabs through the use of Samudra being cages and the use of local materials as potential feed for fattening mangrove crabs before being sold at the market.

Abstract

Ornamental plants are plants that are planted and cared for aesthetic and beauty purposes. Ornamental plants are often used in decorative horticulture, landscaping, and interior design. Algonema is a type of ornamental plant that is popular and often found. Aglaonema has wide, colorful leaves, which often have interesting patterns or patterns. Several varieties of Aglaonema have green leaves with white, red, yellow spots, or a combination of these colors. The high demand for aglonema plants opens up opportunities for producers to commercialize them in and out of the city. However, to achieve the target of marketing outside the city, plant packaging is something that must be considered so that the plants can reach consumers properly and intact. The purpose of this service is to find the right packaging for marketing Aglonema outside the region and determine an efficient marketing strategy to reach consumers and increase marketing. The PKM activities carried out include: mentoring and outreach regarding suitable, inexpensive and safe aglonema packaging techniques for sales outside the region as well as developing a sales strategy to reach a wider range of consumers; business model mapping based on determining target consumers that have been determined by partners; register partners on e-commerce platforms and marketplaces to facilitate the product sales process and reach wider consumers; assistance with e-commerce and marketplace applications to partners; and within a period of 3 months, the service team evaluates the use of e-commerce and marketplaces. After the service is carried out, partners have knowledge about packaging techniques and marketing strategies for aglonema ornamental plants so that partner income increases.

Abstract

The method of transferring the main load to the dummy load is still used in micro hydropower plants. Because the turbine and generator are constantly operating at maximum capacity, the load transfer system, also known as the electronic load control (ELC) system, is ineffective and inefficient. The researcher devised a method for controlling the pressure/flow rate on the branch pipe by using a control valve motorized (CVM). Control valve motorized (CVM) is responsible for the opening and closing of branch pipelines using an electric motor. The goal is to achieve voltage and frequency stability by using CVM to adjust the flow/pressure of water in the branch pipe. The method involves designing and testing the CVM system via a Pelton turbine module connected to the generator. The results of testing the Pelton turbine module with a pressure of 4 kg/cm2 on a 34-inch pipe show that the turbine rotates at 800 rpm. Brushless direct current (BLDC) generator with 12 poles and a Pelton turbine. The proportional integral derivative (PID) controller control parameters are calculated by the control system using the Nichols-Ziggler method, with tuning results of PB 130%, Ti 2.8 seconds, and Td 0.7 seconds. A frequency of 50 Hz and a voltage of 61 volts is produced by controlling the set point (SP) at 55% of the process variable (PV) and the manipulated variable (MV) to CVM at 38%, respectively. The conditions are implemented by varying the load on the system by connecting and disconnecting the load; the system remains stable for 5 seconds.

Abstract

Operations research is widely applied by industrial and business companies to maximize profits or minimize potential losses. In practice, many operations research problems cannot be solved using linear models and require nonlinear models instead. This is the case for Lavera Konveksi, a company that produces long-sleeve t-shirts, collared t-shirts, plain t-shirts, and training pants each month. The company faces issues with fluctuating production quantities and costs. This research aims to develop a nonlinear objective function model to minimize production costs and determine the minimum production cost and the optimal number of items to be produced by Lavera Konveksi. The data used in this study includes production quantities and costs for the period from December 2019 to April 2020. The research employs the Quadratic Programming method, where the nonlinear problem is transformed into a linear case and then solved using the Wolfe Simplex Method. The results indicate that Lavera Konveksi should produce 530 long-sleeve t-shirts, 455 collared t-shirts, 425 plain t-shirts, and 180 training pants to achieve a minimum production cost of IDR 49,436,799.

Abstract

The fuzzy logic of The Tahani model is described as a model used to process data searches, only that this model is based on operations in fuzzy set theory to obtain information that matches its data search criteria. In this study, the fuzzy logic of the Tahani model was applied to help the company PT. Lambarona Sakti in terms of determining recommendations for reordering Honda motorcycles with linguistic criteria against vehicle data that has definite characteristics. The determination of the recommendation of the vehicle to be rebooked from the main dealer is carried out by first doing the fuzzification stage, then determining the degree of membership, then a data search will be carried out based on the desired criteria, the final stage is determined recommendation based on the resulting fire strength value. How the determination of the fire strength value works can be done using the help of the Microsoft Excel application and automatically the results will be in accordance with the filling of the membership degree that has previously been done. 2 possible recommendations were obtained, namely there are recommendation results with all types of Honda motorcycles to be reordered and there are recommendation results with only a few types of Honda motorcycles to be reordered.
