Abstract

Pelayanan informasi yang berkualitas dan memadai merupakan suatu keharusan yang harus disediakan oleh institusi, khususnya institusi pendidikan, untuk memenuhi kebutuhan penggunanya. Dalam rangka menilai kualitas sebuah website, evaluasi usability menjadi sangat penting. Penerapan prinsip-prinsip heuristic evaluation dapat memberikan kontribusi yang signifikan dalam proses evaluasi tersebut. Setelah melakukan analisis usability, ditemukan bahwa terdapat enam prinsip yang terpenuhi dan empat prinsip yang tidak terpenuhi. Prinsip-prinsip yang berhasil terpenuhi meliputi kesesuaian sistem dengan dunia nyata, konsistensi dan standar, pencegahan kesalahan, pemahaman yang lebih penting daripada sekadar mengingat, efisiensi dan fleksibilitas, serta desain yang estetis dan minimalis. Di sisi lain, terdapat empat prinsip yang belum terpenuhi, yaitu visibilitas status sistem, kontrol dan kebebasan pengguna, bantuan pengguna dalam mengenali dan memperbaiki kesalahan, serta bantuan dan dokumentasi. Dalam pengecekan performa website menggunakan perangkat lunak, diperoleh skor 72 untuk performa secara keseluruhan, yang menunjukkan bahwa website tersebut sudah berada dalam kategori yang cukup baik. Namun, hasil yang berbeda terlihat pada pengecekan performa untuk versi mobile, di mana skor yang diperoleh hanya mencapai 61. Hal ini menandakan bahwa performa website pada perangkat mobile masih di bawah standar jika dibandingkan dengan performa pada desktop. Dengan demikian, evaluasi ini menunjukkan pentingnya perbaikan berkelanjutan untuk meningkatkan kualitas dan pengalaman pengguna di berbagai platform.

Abstract

In Indonesia, many users use electricity for light needs. There are two types of light sources, there is man-made light and there is natural light. The light source also only has two methods, namely turning it on and turning it off. No one can set the conditions for the light, in other words it has to be done manually. Therefore, the cause of electricity waste is manual use. In this case, researchers aim to create a control system for this light. With a system that is able to control the light control system automatically. Through a PIR sensor which will control movement to turn on the lights. The way it works is very easy, if there is movement the light will turn on.  Keywords: Arduino, System, Light

Abstract

Photos of heroes are one of the important images in history. Today's hero photos have poor image quality because the camera technology that existed in the past was still simple. Due to technological limitations at that time, the current hero photos are still of low quality with the dominant color being gray. This condition results in the information contained sometimes not being received properly. To overcome this problem, it is necessary to improve the image quality of hero photos which are still of low quality. Image quality improvement is one of the image processing operations which aims to perfect the image by manipulating image parameters. This operation is often applied to images that have poor quality so that the quality can be improved. In this research, we will apply image enhancement operations or improve the image quality of hero photos so that the quality can increase. There are many methods that can be used to enhance images, one of which is histogram equalization which has been widely used to enhance images, especially greyscale images. This method is usually done on images using the Matlab application because of its simple use. This research produces new images with better quality than previous images

Abstract

This study integrates two analytical approaches, Multi-Objective Optimization by Ratio Analysis (MOORA) and Organization, Rangement Et Synthese De Donnes Relationnelles (ORESTE), to identify priority locations for forest and land rehabilitation in North Sumatra. The study evaluates six key criteria, including rehabilitation area size, carbon emissions, ecosystem degradation, biodiversity, rehabilitation potential, and environmental impact, across ten candidate sites. Initially, the MOORA method was applied to assess quantitative factors, revealing that the technical potential among the locations was nearly uniform. Subsequently, the ORESTE method was employed to evaluate qualitative factors, including community participation, socio-cultural values, and institutional support. This analysis revealed significant disparities in social readiness. For instance, South Tapanuli and Mandailing Natal emerged as top priorities due to their robust social support systems, while West Pakpak faced significant social challenges. This integrated approach offers a comprehensive framework that balances both technical and social dimensions for the successful implementation of sustainable forest rehabilitation programs.
