The existence of new students at a tertiary institution is a routine activity every year in a tertiary institution and can also see the sustainability of the tertiary institution. The variety of regional origin of new students makes the party from the university want to see the distribution of new students based on the origin of the school and its place of residence. STIKOM Tunas Bangsa is one of the tertiary institutions in Pematangsiantar. It aims to promote the university. K-Medoids is able to group data on the distribution of new students in STIKOM Tunas Bangsa Pematangsiantar. The clusters produced in this study are of three clusters. The validity used in this study is the validity of Silhoutte Coefficient. The validity value generated in the K-Medoids algorithm produces a validity value of -116.47 by assuming that if the non-medoids value produced S
The development of livestock agribusiness includes all activities that begin with the procurement and regulation of production and marketing suggestions. With the many types of livestock found in Simalungun Regency, Indonesia should be able to increase the potential for livestock agribusiness development. In this study, the authors will analyze the best architecture that can be used to predict the number of livestock populations according to the type of livestock in Simalungun District Indonesia so that certain parties can make improvements to the development of livestock agribusiness in Simalungun District Indonesia. In this study, there are five 5 architectural models namely, 3-5-1 architecture, 3-6-1, 3-7-1, 3-8-1, and 3-9-1. Of the five architectural models, the best architectural model is 3-7-1 with 75% accuracy and 1693 epoch. While the error rate is 0.001-0.01. It is expected that this architectural model can help academics in the process of predicting the number of livestock populations in Simalungun Regency in the coming year.
One way the government determines the level of welfare of farmers is to look at the development of the farmers' exchange rate index. Farmer exchange rate index (NTP) is useful in determining, measuring the ability to exchange products sold by farmers with products needed by farmers in household production and consumption. This study produced an estimate of 4 (four) years ahead from the farmer subsector index of the exchange rate index while the data was obtained from Official News published monthly by the Central Sumatra Provincial Statistics Agency (BPS). The estimation of the farmer exchange rate index will use the backpropagation algorithm, as one algorithm that is quite accurate in estimating and predicting. The problem in this study was that there was a decrease in the percentage of the farmers' exchange rate index of the food crop sub-sector in 2017 which caused a decline in the level of welfare index of farmers in the food crop subsector. This study uses 5 architectural models, that is 3-7-1, 3-15-1, 3-20-1, 3-28-1,3-40-1. Of the 5 architectures, the best is the 3-28-1 architectural model producing an epoch of 7060 with the time needed 01:19 seconds.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
