Abstract

As an intangible cultural heritage, Indonesian Batik continues to develop and is increasingly in demand by domestic and foreign people. In the current era, the concept of making batik that is sustainable or more environmentally friendly has emerged, one of the efforts is in terms of coloring that uses natural dyes. This innovation produces softer batik colors aka soil colors, besides that the manufacturing process is longer than using chemical dyes, so the price is more expensive. With these changes, analyzing the development of sustainable batik sales is important to identify an increase in sales. This study aims to determine the prediction of sustainable batik sales with Monte Carlo simulations precisely and accurately. The data processed is batik production using natural dyes, then converted into probability distributions in the form of compulsive frequencies and then generated random numbers to obtain random numbers. After that, group the interval limit of the random number that has been obtained and continue with the simulation process so that it gets the simulation results and the percentage of accuracy using the Monte Carlo method. The results of the study on data processing from 2020 to 2021 have an accuracy of 90%. So this research is very appropriate for predicting sales for the next year.

Abstract

The role of the agricultural sector can be optimized if it is supported by an integrated sustainable system and capital support. In this study the problems to be discussed are 1) Capital is a problem faced by farmers, 2) Many farmers are able to increase crop yields if they have sufficient capital, 3) Without sufficient capital, farmers will not be able to increase the productivity of their crops. To overcome the problem of lack of capital, farmers borrow money from both formal and informal financial institutions, the purpose of this study is to determine the effect of the efficiency of agricultural credit distribution on the welfare of farmers in the agricultural sector. Agricultural credit plays a very important role in agricultural development: if production increases, farmers' income will also increase. In the research applying quantitative methods where the number of samples is 100 people. With a population of 187 people are farmers in Kedung Lengkong Village, Dlangu District, Mojokerto Regency. In the research the analysis applied is simple regression in order to determine the effect of credit performance on the welfare of farmers. The results of hypothesis testing that credit has a positive influence on happiness is worth the regression coefficient of 0.291. Farmers are helped by credit to buy fertilizers, seeds and others according to agribusiness needs so as to increase profits, as a source of welfare.

Abstract

Boy Delivery is a delivery service in the city of Lamongan which has been operating for about 4 years. Boy Delivery has an average of 12,000 demand per month. However, the high demand was not accompanied by good demand management, Boy Delivery often piled up and even rejected a number of demand due to the unavailability of drivers at that time, this was due to an incorrect prediction of demand. Therefore this research was conducted to help forecast future demand using the Single Moving Average, Weighted Moving Average, and Exponential Smoothing methods. Of the three methods, the Single Exponential Smoothing method was obtained as the best method with the most accurate results with a smaller error of 5.481%.
