Forecasting is an attempt to project future events using relevant information from the past. Using such data, forecasting serves as an effective means of planning activities and reducing the likelihood of errors in predicting the course of future events. One method of prediction is the Single Exponential Smoothing method. The research is aimed at predicting the amount of pineapple production in Riau Province by 2023. The study utilizes information on the number of pines production in the Riau province as many as 10 datasets covering the period from 2013 to 2022. This data is obtained from the official website of BPS Province Riau. In this study, the researchers used quantitative methods. Based on a solver analysis in Ms.Excel, the results showed that the forecast accuracy rate reached 71.64% with the smallest error presentation of about 28.36% which categorized these forecasts quite well. Using this method, the forecast quantity of pineapple production in Riau Province for 2023 is 262,637 tons.

2024-02-28T20:29:56+07:00

Based on the iPrice.co.id website, there are five e-commerce sites in Indonesia with the highest number of visitors. This is caused by the competitive strategy implemented by each e-commerce in order to win or maintain competition with consideration of the most attractive strategy for potential customers. The purpose of this study is to determine the best competitive strategy that needs to be implemented by e-commerce using game theory and consumer evaluation of e-commerce and supporting variables using the AHP (Analytical Hierarchy Process) method. The sample of this research is Jakarta citizens who are e-commerce users. The results of the research on the AHP method obtained e-commerce ranking results with the highest priority ranking to the lowest, namely Tokopedia, Shopee, Lazada, Blibli and Bukalapak. The variables that consumers pay attention to when making purchases on e-commerce from the highest priority to the lowest, namely Security, Trust, Free Shipping, Lots of Promos, Price, Product Quality, Payment Methods, Web Appearance, Product Brands and Product Diversity, where the 6 variables with the highest priority are then selected and these variables are used to determine the best competitive strategy using the game theory method. The results from game theory show that for Tokopedia e-commerce it is necessary to use a Product Quality strategy, Flood of Promos, and Trust, for Shopee namely Free Shipping, Lots of Promos and Security, for Lazada namely Product Quality, Free Shipping, Lots of Promos, and Security, for Bukalapak namely Product Quality, Price, Free Shipping, Lots of Promos, Trust, and Security, for Blibli namely Price, Free Shipping, Lots of Promos and Security.

2024-02-28T20:29:38+07:00

Daily weather forecasting is an important aspect in anticipating and managing the impact of weather changes that can affect various sectors of life, such as agriculture, transportation, tourism, and other activities. Purwokerto City, which is located in the middle of Java Island, Indonesia, is one of the cities that faces fluctuating weather changes. This research aims to perform daily weather forecasting in Purwokerto City using the Markov Chain Method, a statistical approach that has been widely used in various fields including weather forecasting. This research uses daily weather data in Purwokerto City on July 5 to 10, 2023. The data was obtained from the Meteorology, Climatology, and Geophysics Agency (BMKG) Purwokerto City. The weather data is based on the weather categories of cloudy, light rain, moderate rain, and thunder rain, as well as observation time which includes morning, afternoon, evening, and night. The results showed that the daily weather data from July 5 to 10, 2023 analyzed showed significant weather variations. However, cloudy weather was the most dominant condition during that week.

Pola Frieze dan Pola Kertas Dinding pada Masjid Istiqlal

2024-02-28T20:29:13+07:00

The beauty of Istiqlal Mosque is reflected through its architectural design. The decorative arts that adorn this mosque are generally found in elements such as doors, windows, walls, gates, and vents, which show special patterns. Such patterns can be identified through the concept of geometric symmetry, specifically Frieze Patterns and Wallpaper Patterns. The Frieze pattern is a subgroup within a symmetry group formed through one-way translation, creating a linear pattern that repeats in one direction. There are seven types of frieze patterns, each formed through a combination of specific isometries. Along with that, there are also other geometric patterns known as wallpaper patterns. Wallpaper patterns analyze patterns based on transformations on a flat plane and have seventeen types. This study aims to explore and explain geometric patterns based on Frieze Patterns and Wallpaper Patterns contained in the decorative arts of Istiqlal Mosque. Data collection methods involve observation and documentation. The results showed that there are certain frieze patterns in the Istiqlal Mosque, such as the type . Meanwhile, the wallpaper patterns identified in the design of the Istiqlal Mosque are type pmm and pmg. It is important to note that not all designs in the decorative arts of Istiqlal Mosque can be categorized into seven frieze patterns as well as seventeen wallpaper patterns.

Siak Sri Indrapura is a regency located in Riau Province. Siak Regency is expected to become a tourist destination capable of attracting visits from both domestic and foreign tourists. For travelers who are visiting Siak Palace For those experiencing it for the initial time, of course they will have difficulty determining the direction of the road, so tourists use alternative technology such as Google Maps to determine their direction of travel. In Google Maps there are various travel routes, to save time tourists will defi-nitely choose the shortest travel route. To determine the shortest route, of course, re-quires calculations to avoid mistakes. In this research, the shortest route from Pek-anbaru to Siak Palace was carried out using The algorithms of Dijkstra and Bellman-Ford. This algorithm was chosen because it can help calculate the shortest route that tourists can take. It was found that in the last iteration The Dijkstra algorithm and the Bellman-Ford algorithm, both of which travel route from Pekanbaru to Siak Palace was 125.1 km with a node route (Jalan Raya Pekan – Jalan SM Amin – Jalan Raya Panjang Okura – Jalan Perawang Siak – Jalan Buatan – Siak).
