Abstract

The ability to process data is to process raw data into useful information for users, in this case, PT. Mod Indo finds it difficult when making procurement decisions because there are factors that must be considered, namely the expenditure of goods, the need for goods, and the allocation of goods. The absence of a patented system causes some employees to frequently use estimates so that excess inventory often occurs for a long time which results in damage to goods. To realize better performance, it is necessary to build a decision support system in the supply of goods stock. This study aims to design and build a decision support system to help control inventory at PT. Indo mod. The system developed uses the programming language PHP and MySQL as a database, using the ABC Analysis Method which is a calculation of the distribution of classes based on the value of an item. In the study, testing 100 data on this system produced a cumulative 78.98% cumulative item group A category with 15 total items, 11.05% cumulative item B group with 10 total items, and item C group 9.97% cumulative 75 total goods. Classification of goods produces appropriate data, namely in the form of data that has the highest priority to be controlled. With this system, it can help PT Mod Indo to track, plan, and control inventory optimally, so that it can identify goods with fast, medium, and slow turnover, and can increase work efficiency and production for employees

Abstract

In developing countries, chronic malnutrition leads to stunting. Stunting will become a public health problem in Indonesia resulting in a decline in the quality of Indonesia's human resources in the future. In the modernization era, determining the nutritional status of toddlers can be simplified automatically. The author's C4.5 algorithm was used to classify and predict the nutritional status of toddlers in Bringin sub-district, in addition to testing using the system that the author built, the author also conducted manual testing and testing using RapidMiner as a comparison. Based on the analysis of the results of 186 datasets tested using this system, predictions were made of toddlers with male gender categories, very underweight and height predicted that the toddlers were in the malnutrition category. For the performance of the dataset tested obtained an accuracy of 84.221%, there was a difference of 6% from the test results using RapidMiner which obtained an accuracy of 91.40%. The use of algorithms is highly recommended to classify the nutritional status of toddlers. The application of the toddler nutritional status classification system that the author designed is feasible because it can be faster and more effective in classifying the nutritional status of toddlers based on the zscore set and there is only a difference of 6% from the same dataset prediction testing using rapid miner. Based on the dataset of system test results, it can be concluded that 89.24% of toddlers in Bringin sub-district are well nourished.

Abstract

Tenun Resti Sipirok is a company engaged in trading woven products such as Jas, Ulos, Souvenirs and other woven products. In marketing its products, Tenun Resti Sipirok still uses the shop as a marketing place, so that consumers who are interested in buying these products must come directly to the store where they are marketed. Not infrequently consumers are disappointed because the product they want to buy is not available which requires consumers to order in advance until the product is finished being produced. By designing and implementing a web-based marketing system with a CRM approach to Tenun Resti Sipirok, it is very helpful in the process of marketing products via the internet, such as selling and promoting products to consumers. This also has a positive impact on the consumer side, because consumers do not have to come directly to the marketing shop, but consumers can buy and order products through the website that is created and information about new products and promos is easy for consumers to get through the website page as well as via email messages.

Abstract

Education equality for the Indonesian people still needs to be improved; for example, in Indramayu, the average length of schooling for the community has only reached 6.52 years (2021) and 6.83 years (2022), still below the 12-year compulsory education program. One way of equitable distribution of education through digitisation of the Education module still needs to be solved, especially related to uneven internet access facilities and the high price of internet quota. Therefore, it is necessary to carry out this activity so that a system that contains digital learning modules can be produced without using internet quota. This activity aims to digitise learning modules that can be accessed without internet quota to accelerate education equity for Pabean Udik Village Indramayu school students. Activities are carried out by designing a system consisting of hardware, web-based applications and learning module content, both K-13 modules and Virtual laboratories. The result obtained is the availability of a system that contains learning module content and virtual laboratories that can be accessed without internet quota using smartphones, tablets and computers. This system is expected to be a solution for equitable development, especially for students in Indramayu, to increase students' knowledge even though the average school time is still below national standards. This system can also be implemented in other regions to accelerate education equity in Indonesia.

Abstract

In this era, laptop users are increasing rapidly to support people's work. Various types and brands of laptops have been produced and distributed on the Indonesian market with various specifications and different uses. Survey results from indonesiabaik.id show that the use of laptops without internet for work is 54.55%. Meanwhile, laptops used for entertainment were 34.94%. With various types, specifications and uses of laptops having varying prices from cheap to expensive, this creates a dilemma for people in choosing a laptop that suits their needs. Many people have already bought laptops, but the increasing demand ends up having to buy another laptop to suit the increasing work and entertainment needs. The method used for comparison is the SAW method with the WP method in a web-based application that can recommend laptops. The results of this research show that recommending laptops using the SAW method or the functionally WP method is very helpful in finding out the overall ranking or level of the laptop. However, in terms of effectiveness, the SAW method still has the possibility of having the same ranking value and that could cause a dilemma for people in determining the ranking order on laptops. Meanwhile, the WP method has the possibility of the same ranking value being very small so it can determine the laptop ranking order better than the SAW method. From the overall comparison, it can be concluded that the WP method is better in recommending laptops.

Abstract

Empirical studies state that the environment is the main factor that influences crime patterns, so closed circuit television (CCTV) is an option to reduce the risk of crime. However, CCTV is less effective because it requires high bandwidth & storage and cannot provide notifications. Therefore, a technology called the internet of things (IoT) has emerged so that CCTV or webcams can work together with sensors to detect the presence of intruders and provide notifications. This research proposes a system that detects intruders and sends notifications to home owners without being tied to time and place. This system is usually referred to as a smart home security system. This research aims to compare intruder detection algorithms in IoT-based home security systems. This research method uses the internet of things (IoT) in smart homes or home security by comparing the accuracy and processing time of the HoG+SVM and Yolo V3 algorithms. The results of the system implementation show that the most accurate intruder detector is the Yolo V3 algorithm with an accuracy of 99% and a processing time of 14.852 seconds. This processing time can be accelerated by using a Graphics Processing Unit (GPU) with higher specifications.
