Abstract

Image watermarking is a technique for inserting hidden information into digital images to maintain the authenticity and integrity of documents. This study discusses the application of the Discrete Cosine Transform (DCT) method in the watermarking process on the value image stated in the Competency certificate. The DCT method allows the insertion of watermarks on the image's frequency domain, where information can be embedded without compromising the visual quality of the certificate. This implementation aims to ensure that certificates remain authentic and not easily manipulated. The embedding process is carried out by inserting a watermark on a high-frequency component that is invisible to the human eye, while the extraction process is used to verify the authenticity of the certificate. The results show that the DCT method provides reliable protection against image modification, as well as maintains the validity and security of data integrated in the competency certificate digitally.

Abstract

The management of palm oil solid waste, particularly Empty Fruit Bunches (EFB), remains a major challenge in the palm oil industry due to its potential to cause environmental pollution if not properly handled. One solution to this problem is selecting appropriate disposal sites by considering various technical, environmental, and social criteria. This study aims to implement a Decision Support System (DSS) using the Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) method for selecting palm oil waste disposal locations in Pagar Merbau. The criteria applied include land area, number of trees, soil type, plant age, nutrient requirements, and soil fertility. The system was developed using PHP and MySQL, and tested with the blackbox testing method. The results show that the system effectively supports decision-making by ranking alternative sites based on their highest preference values. Therefore, the implementation of a TOPSIS-based DSS proves to be effective in determining the most optimal location for palm oil waste disposal.

Abstract

A health facility or health service facility is a tool or place used to carry out health service efforts, both in terms of promotive, preventive, curative and rehabilitative carried out by the central government, regional government or the community. This research contains development applications that cover every hospital, health center, and practice clinic located in the Langkat Regency area with the aim of facilitating the community in finding the nearest hospital, health center, and practice clinic. The application built can display the location of the health facility in map form and can display information in the form of name, address, telephone number, photo of the health facility, services available there, working hours, and further information on the place. In this study, the search for health facilities is only subject to distance as a health facility criterion, so that it can be developed further. To find the closest route to a health facility, here the author uses the Dijkstra Algorithm method which has been widely researched to be applied to the shortest route search system. This algorithm was invented by Edsger Dijkstra, a computer scientist from the Netherlands. The way Dijkstra's algorithm works is with a greedy strategy, namely at each step it chooses the side with the smallest value that connects the selected and unselected nodes/nodes. This algorithm requires a point of origin and a destination with the final result being the shortest distance from the point of origin to the destination along with the route.

Abstract

Expert system is a computer program designed to emulate the abilities of an expert in solving problems in a particular field. This system can assist in making a decision and provide a solution based on the data that has been obtained. Delia General Hospital (RSU) is a hospital in Langkat district that provides health services to the community to cure diseases, one of which is cholesterol. Cholesterol is a fatty substance contained in the blood and produced by the body. Cholesterol has an important role in helping to produce hormones and form cells. However, if the level of cholesterol in the blood is too high, it can cause health problems such as atherosclerosis, stroke, and heart disease. Increased cholesterol levels occur in adolescents due to unhealthy lifestyles and consuming foods high in fat. Certainty factor is a method in artificial intelligence that is used to determine whether a fact is certain or uncertain and provides accurate results by calculating the weight of symptoms determined by an expert and can produce answers to uncertain questions.

Abstract

Sugarcane (Saccharum Officanarum L) is an annual plantation crop, which has its own characteristics, because it contains sugar in its stems. Sugarcane belongs to the grass family (graminae) like rice, reeds, corn, bamboo and others. One of the problems that exist in sugarcane plantations at PT Perkebunan Nusantara II is stem borer pests. Losses due to borer attacks can be in the form of a decrease in sugarcane weight, yield and quality of the sap obtained. pests on sugarcane plants cause a decrease in sugar production of about 10%. There are three types of stem borer pests found in PT Perkebunan Nusantara II, namely shoot borer pests, striped stem borer pests, and giant stem borer pests. Meanwhile, biological control is by spreading natural predators of pests which will suppress the population of widespread distribution and breeding of pests which are commonly called parasitoids. Parasitoids will become predators of their respective hosts, so appropriate diagnostic therapy for stem borer pests is needed so that the spread of stem borer pests does not become more widespread and the parasitoids to be spread operate effectively. By using the Certainty Factor method, you can find out the types of pests that are attacking sugarcane plants. Based on manual calculations, the dipole yield was 79% on one of the selected pest types based on the symptoms induced in the sugarcane plant.

Abstract

Palm oil is a very important commodity besides oil and gas which also has a fairly good export value. The palm oil produced must be supported by the quality standards set by SNI. The level of maturity when harvesting oil palm fruit greatly influences the quality of Crude Palm Oil (CPO) production, which is crude palm oil that has a reddish color obtained from extraction or from the pressing process of oil palm fruit flesh. In fact, in the field of oil palm fruit harvest, there are still many oil palm fruit that are not ripe enough and can even be said to be still raw, entering the CPO production process. Determination of the maturity level of oil palm fruit is generally determined based on the amount of loose fruit and color, so handling the harvest of oil palm fruit is an important activity in improving the quality of CPO. It is necessary to build a system capable of managing and processing palm fruit images to measure the maturity level of the palm fruit to be produced. To obtain the right level of accuracy, this research uses the Learning Vector Quantization (LVQ) method. LVQ is a method for conducting supervised competitive layer learning. From the results of trials conducted, it is proven that the system can measure very ripe oil palm fruit with HSV values (0.052209; 0.896021; 0.791114).

Abstract

PT Perkebunan Nusantara II (PTPN II) Sei Semayang, a state-owned enterprise (BUMN) engaged in palm oil and sugarcane production. Security officers play a crucial role in maintaining the company's security and productivity. Currently, the security officer recruitment process remains conventional, relying on subjective assessments based on several criteria. The aim of this study is to introduce a more structured, transparent, and objective approach to security officer recruitment. By implementing the Analytic Hierarchy Process (AHP) method, decisions in selecting prospective security officers can be made based on predetermined criterion weights. AHP enables decision-makers to identify, compare, and prioritize relevant criteria, addressing the complexity of selecting candidates who fit the established criteria. Through this approach, the study seeks to enhance efficiency and effectiveness in the security officer selection process, reduce the risk of errors in candidate selection, and improve overall company performance and security. It is hoped that the application of the AHP method in the decision support system for security officer recruitment at PTPN II Sei Semayang will assist the company in optimizing the selection process and supporting more data-driven decision-making.

Abstract

Book is a window to the world. By reading books, we can get a variety of knowledge that we do not know. The meaning of books as windows to the world can be doubted today. Given the internet provides a lot of information with a much more attractive appearance. Both books and the internet provide a wealth of information and knowledge. But in fact books are still the mainstay of accurate sources of knowledge. A lot of information on the internet is in fact not supported with accuracy. Even in the world of higher education, books are the main reference source in scientific writing. However, old books that may have started to become dull and the writing can no longer be read resulted in the reader of the book not being able to know the knowledge contained in the old book. Based on observations, it is necessary to build a computerized system so that the writings in the book can be read again. One method that can be used is the Thresholding method. The system is designed with MATLAB programming application. In this process, it is necessary to scan or take photos/pictures from cellphone cameras from old book manuscripts to be processed on the system using the Thresholding method. After carrying out the testing process on several images of old books, better results were obtained so that the writing on the manuscript could be seen more clearly with different threshold values for each image entered into the system.

Abstract

Kriptografi merupakan ilmu dan seni untuk menjaga keamanan pesan ketika pesan dikirim dari suatu tempat ke tempat lain. Kriptografi digunakan agar kerahasiaan pesan tersebut dapat terjaga, sehingga tidak diketahui oleh orang lain. Kriptografi ini muncul atas dasar keamanan dari suatu bentuk informasi-informasi penting yang bersifat rahasia. Steganografi merupakan cara menyisipkan pesan ke dalam media tertentu misalnya gambar, audio, video, dan lainnya. Cara ini terbukti efektif untuk mengamankan pesan teks dengan cara disisipkan pada file gambar, dan pesan tersebut tidak akan diketahui oleh pengguna lain jika didalam gambar yang sudah disisipkan pesan terdapat suatu pesan rahasia. Dan dalam penelitian ini dilakukan proses enkripsi dengan algoritma One Time Pad (OTP) XOR untuk mengubah pesan teks menjadi chiper atau pesan acak dalam bentuk bilangan biner. Kemudian chiper tersebut disisipkan ke dalam file gambar melalui bit-bit paling tidak berarti dengan metode Least Significant Bit (LSB).
