Abstract

The purpose of this research is to provide the new innovations on mapping of poverty characteristics in West Nusa Tenggara Province using Biplot analysis. The analysis based on matrix transformation, singular value decomposition, and matrix factorization. In this research we construct two kind of matrix transformation, that are average transformation and standarization transformation. The result of this research is symmetry Biplot, which maps the regency and  poverty characteristics simultaneously. The result of Biplot mapping with average transformation obtained the value of  (79.12%), while standarization transformation obtained the value of  (63.11%). It can be concluded that Biplot mapping with averaging transformation is better than standarization transformation.

Abstract

In this research, integer linear programming of vehicle’s setting in Lombok International Airport is solved by Branch and Bound Method. Branch and Bound is the method that can deliver integer solution of the linear programming. The optimum result is parking area’s income of Lombok International Airport can be achieved until Rp1.218.690.000/month with lade of 384 unit’s of motorcycle, 990 units of class I of the car, and 21 units of the bus or truck with the length < 9 m. If we make a comparison between the maximum income with the number of tax in number Rp90.074.550, then the number of the tax is only 7,31% of the maximum income. So that, in the other words we can say that the number of tax which accepted by Central Lombok’s Government is not representative with parking area’s income which can be acquired.

Abstract

Zero-one integer programming is a mathematical method to solve the scheduling problems, such as nurse scheduling (cyclic scheduling) using Branch and Bound method. In cyclic scheduling method every nurse will work over a period of time (n days) and will take place periodically. The aim of this research is to give an alternative nurses scheduling which optimize the preference of each nurse that maximize the nurses performance and maximize hospital service. This research divided into three steps. First observations for actual hospital schedule, the second stage, formulation the actual schedule into linear programming model and solving the problem. Last, the solution from second step, transformed into the real problems, that is job schedule for each hospital room. Based on the analysis results the optimal schedule are obtained which maximize the quality of assignment for each shift, regard the job load and job constrain. Furthermore, there are significant different of both scheduling in quality and fairness aspect, examine scheduling is more dominant. Meanwhile, in three other aspect of coverage, stability and stability, both of schedule has the same characteristics.

Abstract

UMKM Bunda Rasya is a home industry that is engaged in the production process in managing raw materials for bananas and sweet potatoes into a product of banana chips and sweet potato chips which will be marketed as snacks for the Indonesian people. Until now, Bunda Rasya UMKM do not have a marketing system, so there is no promotion of the products they produce. The order for chips has not experienced a significant increase so far, and even experienced a slight decrease in sales due to decreased production per day. Based on the observations of researchers in an effort to restore the current condition of UMKM sales due to the impact of the Covid-19 pandemic which has not yet been completed, that one of the factors that influence the lack of sales orders is the absence of marketing. So that it is difficult for companies to get new consumers, given the importance of marketing in a business, a strategic plan is needed to determine the right marketing strategies for Bunda Rasya UMKM, namely digital marketing. The steps for using digital marketing are as follows: 1. Determine a personal buyer. 2. Identify the needs of the target market. 3. Prepare a marketing plan. 4. Take advantage of various digital marketing media (google my business, instagram, facebook, whatsapp business, website, etc.). 5. Apply an attractive copy writing strategy. 6. Use marketing tools for business. 7. Understand digital marketing metrics and evaluations. After making direct observations during the activity, this activity gave results, namely providing input to business management in making product marketing strategies. business management becomes more mastered and understands the importance of marketing strategies in the business world, especially UMKM in the field of digital marketing
