Abstract

The purpose of this study is to apply the word2vec algorithm to recommend search results in online catalogs. The reason for taking this title is because, based on the results of observations and the observations of researchers, the data search process, especially in online catalogs, only reaches the syntactic level. So that the results are given only up to the syntactic level. Therefore, researchers utilize the word2vec algorithm, which has the ability to represent words at the semantic level, to carry out a search process where the results of this process are used as alternative search results or recommendations for search results. The data that the researchers used was data on 12,701 book titles in the Raja Ali Haji Maritime University library. To evaluate the recommendations for the search results obtained, the researcher tested the recommendation system for search results using several scenarios, and then the results were measured using a precision test on the k document (P@k). From the results of the precision test measurements on the k document, various results were found. Scenarios 1 and 2 show a fairly high precision value with a value of 0.53 and 0.59, while for testing in scenarios 3, 4, and 5, the resulting precision value is relatively low with a value of 0.50, 0.42, and 0.14.

Abstract

Indonesia as an agricultural country with the majority of the population as farmers, faces the challenge of narrowing land due to the times with building construction and land clearing. In an effort to overcome this narrow area, the Verticulture method was used, where planting was carried out in stages or vertically. This method is suitable for growing vegetables, medicinal plants and ornamental plants, including red lettuce which has high economic value and is rich in nutrition. However, routine plant maintenance, such as watering and fertilizing, is often forgotten due to the busyness of plant owners. To overcome this problem, IoT technology is used with the Wemos D1 R2 Board as a substitute for Arduino, YL-69 sensors, water pumps, and Telegram Bots as a liaison with users. Testing of the IoT prototype system shows the success of the YL-69 sensor in reading soil moisture data and detecting the state of the planting medium. Water pumps and fertilizer pumps can function according to a predetermined humidity value and time. The water pump is successfully started according to the predetermined soil moisture value, which is more than 13000 and successfully turns off when the soil moisture value is less than 11500. The fertilizer pump is also successfully started according to the time determined using the RTC DS3231, namely on Wednesday at 08.00 and turns off after 1 minute.

Abstract

This study investigates the mechanical behavior of extended end-plate moment connections in steel structures, with a focus on the variations in stiffener angle and position. Utilizing finite element analysis (FEA), three models featuring different stiffener configurations were assessed to evaluate their rotational capacity and displacement characteristics. The results indicate that adding a stiffener to the moment connection between the beam and the column at the bottom of the connection increases the rotational capacity by 32.60% when comparing the flush type of end plate to a model with a 45° single rib stiffener. Additionally, the implementation of double stiffeners significantly enhances the rotational capacity, improving performance by up to 59.85% compared to unstiffened configurations. Increasing the angles of the stiffeners further optimizes load distribution and structural integrity. These findings highlight the importance of stiffener design in moment connections, particularly regarding rotational capacity. Future research should explore the effects of bolt pretension and the use of varied bolt diameters for further optimization.
