Abstract

In Indonesia, motorbike repair shops have become a necessity for motorbike riders. The large number of motorcycle repair shops makes it difficult for users to determine the right repair shop according to their needs. Thus, the role of the recommendation system is needed. In order to meet the need for various criteria, a recommendation system for selecting a motorbike repair shop was built using a case study in Gading Serpong. The criteria used are distance, service, speed, price, and comfort of the waiting area. The TOPSIS method (Technique for Order Preference by Similarity to Ideal Solution) is a multi-criteria method that is computationally efficient and is able to measure the relative performance of various decision alternatives in simple mathematical form. Therefore, this research system was built using the TOPSIS method. The test results in this research show that the TOPSIS method has been implemented correctly. Apart from that, a success test of the recommendation system has been carried out by distributing questionnaires, with a success percentage of 82.24%. The questionnaire results obtained have also been tested using Cronbach Alpha, with a result of 0.81, which means that the questionnaire results obtained can be trusted

Abstract

The security of the data (message) sent is very important in maintaining the confidentiality of the message. Many algorithms can be used to secure messages. Among them is the Hill Cipher algorithm. The Hill Cipher algorithm is a classic cryptographic algorithm. This algorithm uses a square matrix key. In connection with the Hill Cipher algorithm key, this literature aims to examine the matrix that can be used as a key in the encryption and decryption process in the Hill Cipher algorithm. In this literature, we take a square matrix of order 3x3 and use 36 characters (A-Z, 0-9). To produce cipher text, the method used is to carry out an encryption process based on the Hill Cipher algorithm. The encryption process is carried out by multiplying the key matrix by the plaintext. The decryption process to get the plain text back is done by multiplying the ciphertext by the inverse modulo matrix of the key matrix. The encryption process can always be carried out, but not all decryption processes can be carried out. Because not all matrices can be used as key matrices. The results of this literature show that the key matrix must be a matrix of order mxm. A matrix with determinant value = 0 cannot be used as a key. Likewise, a matrix whose determinant value is not relatively prime with the number of characters to be encrypted or decrypted cannot be used as a key matrix

Abstract

Fire, as a serious disaster with destructive impacts involving loss of material and human lives, is mainly triggered by electrical short circuits due to massive construction and the use of cables that do not comply with standards. The importance of developing electric power that complies with safety standards to protect people and property cannot be overstated. Electrical integration is aimed at increasing system efficiency, but electrical short circuits remain the main cause of fires, accounting for 45% of cases in Indonesia in 2021. To reduce the risk, preventive measures are needed such as repairing the electrical network, using standard equipment, and educating the public. A light fire extinguisher (APAR) is one of the highly recommended fire prevention media. The appropriate APAR for household needs is the Chemical Powder / Dry Cemical type because it is almost effective for all classes of fires, especially for electrical short circuits. But in purchasing we are faced with the many brands available as well as limited needs, desires and financial capabilities. In this context, a web-based Decision Support System (DSS) was developed using the Weighted Product (WP) method to select the Brand of Light Fire Extinguisher (APAR). The WP method gives weight to the criteria of price, quality and reliability, helping households choose an APAR that suits their needs and budget. The application of this method is expected to minimize errors in selecting the APAR brand, increase accuracy, and make it easier to use for those who want to make a purchase. This SPK makes a positive contribution in helping users make APAR purchasing decisions that suit their needs and preferences.

Abstract

PT Pinus Merah Abadi is a company engaged in the sales and distribution business with a distribution network spread throughout Indonesia, both through traditional and modern channels. Currently PT Pinus Merah Abadi carries out the employee selection process on average 2 (two) times a year with a total of 50-60 job applicants. The assessment process when selecting employees uses multiple criteria, namely assessment during psychological tests, competency tests and interviews. The employee selection process still has several problems, including subjectivity in the assessment process and it takes a long time because it is done manually, resulting in the decision making process being slow. Based on these problems, research is needed as a system innovation in making decisions regarding the selection or selection of new employees at PT Pinus Merah Abadi applies a simple additive weighting method based on six criteria, namely: test, education, age, experience, readiness and expertise. As a result, this system can help make it easier for HRD to select employees based on the highest ranking results.

Abstract

Stunting is a condition in which the development and growth of children are stunted due to malnutrition. In Indonesia, 21.6% of the approximately 300 million stunting cases still exist. In an endeavour to combat stunting, the Indonesian government is holding posyandu at the lowest levels of government. Despite these efforts, a significant number of parents do not receive information about stunting. Therefore, this study will develop a web-based information application about stunting. The application is developed using the cascade methodology. The conclusion of this analysis was that the waterfall methodology is still applicable for small development teams. The application can then provide information on child development and malnutrition at any time.
