Abstract

Pertanian merupakan salah satu hal yang sangat penting dalam kehidupan masyarakat Indonesia. Sebagai negara agraris, Indonesia memiliki tanah yang subur dan merupakan wilayah dengan sinar matahari yang baik serta curah hujan yang tinggi. Kemudian dilihat dari kebutuhan masyarakat Indonesia terhadap bahan pangan seperti buah-buahan dan sayur-sayuran semakin meningkat setiap tahunnya, kebutuhan buah-buahan dan sayur-sayuran pada tahun 2014 sebanyak 11.918.571 ton, meningkat sebesar 3,12% dibandingkan tahun 2013. Kawasan pemukiman masyarakat perkotaan yang terbatas jumlah pekarangannya karena padatnya jumlah penduduk. Metode hidroponik hadir menjadi solusi. Teknik menanam tanaman dalam media nutrisi dengan atau tanpa menggunakan substrat inert seperti kerikil, vermikulit, rockwool, lumut gambut, serbuk gergaji, semak kelapa, sabut kelapa, dan lain sebagainya. Kelompok Petani Perkantoran Kebun Hidroponik Taman Solo KPK KHITAS dalam perjalanannya sudah mampu menjual hasil panen seperti sawi, pakcoy, kangkung, bayam, selada air dan sayur-sayuran lainnya untuk warga yang berada di sekitar kebun. Pada sistem berjalan KPK KHITAS kegiatan pemasaran dan promosi produk, serta informasi masih di sekitar lingkungan kebun hidroponik yang menyebabkan penjualan dan produk dari pertanian tidak mengalami peningkatan. Tujuan penelitian ini adalah membuat website yang dirancang menggunakan metode waterfall dengan tahapan yang dimulai dari analisa kebutuhan, desain sistem, pengujian program, penerapan program dan pemeliharaan, serta pengumpulan data dengan cara wawancara, observasi dan tinjauan literatur. Hasil penelitian berupa Website yang dibuat untuk meningkatkan pemasaran produk serta memudahkan pelanggan untuk membeli produk secara online dan mempermudah dalam membuat laporan keuangan.

Abstract

Advances in technology have led to an increase in the frequency of smartphone, social media, and various digital app usage in daily life. These digital activities give rise to various digital behaviors—such as screen time, number of notifications, social media usage, and sleep patterns—which can be evaluated to understand users mental health. High digital device usage is suspected to be associated with increased anxiety levels among users. Therefore, this study aims to analyze the impact of digital behaviors on anxiety levels by utilizing explainable machine learning approaches and AI. This study uses the dataset, comprising 500 data points obtained from Kaggle. The research stages consist EDA, feature engineering, target leakage evaluation, comparison of several machine learning algorithms, cross-validation, and model interpretation using SHAP. Based on the EDA results, the variables social_media_time_min, notification_count, and digital_addiction_score showed a positive relationship with anxiety_level. During the model-building process, the variable digital_wellbeing_score was removed because it had a very high correlation with anxiety_level -0.84, which could lead to potential target leakage. The algorithm comparison revealed that the Ridge Regression model performed best compared to Random Forest, SVR, and XGBoost Regression, with an R² score of 0.221 and an RMSE of 1.627. Additionally, the results of 5-Fold Cross Validation showed an average R² Score of 0.158 with a standard deviation of 0.062, indicating that the model demonstrated fairly consistent performance. The SHAP interpretation reveals that notification_count and social_media_time_min are the variables that most strongly influence the prediction of anxiety_level. The results of this study indicate that digital behavior affects users anxiety levels, although the relationships among the variables remain quite complex. This study also emphasizes the importance of evaluating the target leakage and understanding the model in the development of machine learning-based mental health analysis to ensure that the prediction results are more objective and clear.

Abstract

A company profile website is a digital medium used by companies to effectively convey information about their profiles, services, and portfolios to the public. In the era of digital transformation, the existence of a website is crucial because it can increase a company's visibility, credibility, and competitiveness. This study aims to design and develop a CodeIgniter 3-based company profile website that adapts to user needs and facilitates content management. Needs analysis was conducted through observation and interviews, while the system design utilizes UML and a responsive interface design that supports various devices. The implementation used PHP with the CodeIgniter 3 framework and a MySQL database. The results show that the website is capable of displaying profile information, services, portfolios, blogs, and contacts, as well as providing a simple CMS for independent content updates. In conclusion, this website can enhance professionalism, strengthen branding, and simplify the management of company information. Further developments could include social media integration, SEO optimization, multi-language support, and visitor analytics features. Additional security features and performance enhancements could also be considered to ensure the system's sustainable quality and reliability in the future.

Abstract

Abstract—The role of the hospital is very helpful in efforts to improve the quality of public health, for this reason the need for fast and appropriate services so that human resources are maintained for their survival. At dr. Hospital Hendrikus Fernandez Larantuka East Nusa Tenggara, the registration service still uses the intranet system or local network and system errors often occur so that the patient registration process is hampered. In addition, the system created on the intranet network also has drawbacks, one of which is that it can only be accessed by people who are connected to the building's network. With these problems, there is a need for a mobile-based application that can be accessed directly by the public in real time from anywhere and any time. The purpose of this study is to create a mobile-based application design that is capable of processing inpatient registration services at hospitals with an attractive and user-friendly appearance. The method used in this study is the prototyping method. This method is a software development model by creating a prototype or model to provide an overview to the user by going through 5 stages, namely communications, quick plan, quick design model, prototype construct, and development delivery and feedback. The tool used in making this prototype is the Figma application. The results of this study are that there is an application prototype that can be used as reference material for RSUD dr. Hendrikus Fernandez Larantuka, East Nusa Tenggara, in developing his system so that the inpatient registration process can be carried out by the community anytime and anywhere. Likewise, information from the hospital can be received in real time by the public through the mobile-based hospital inpatient application.
