Abstract

Tanaman hortikultura adalah cabang pertanian tanaman yang berurusan dengan tanaman taman. Tomat (Lycopersicumes culentum) merupakan salah satu jenis tanaman hortikultura bernilai ekonomis tinggi, untuk itu cara menanam  tomat yang baik perlu diperhatikan, dikarenakan tanaman tomat sangat rentan terhadap kelebihan dan kekurangan air selama masa pertumbuhan. Selain perawatan berupa penyiraman air Salah satu tehnik  budidaya yang berperan dalam upaya meningkatkan pertumbuhan tanaman tomat adalah pemupukan. Efisiensi pemupukan perlu dilakukan dengan tujuan memperkecil kehilangan pupuk dan meningkatkan efektifitas serapan hara. Penelitian ini bertujuan untuk membuat sistem yang mampu  mengendalikan suhu, memantau kadar air dalam tanah dan memupuk secara teratur, serta dapat memberikan laporan sistem, berinteraksi melalui suatu antarmuka (interface) yang mudah digunakan, yaitu smartphone. mikrokontroller yang digunakan sebagai pusat pemrosesan data adalah arduino uno. Dari hasil pengujian telah terukur bahwa sistem mampu memberi tindakan terhadap perubahan suhu, kadar air dalam tanah yang melebihi atau kurang dari batas yang ditentukan. Sistem mampu mengirimkan nilai-nilai sensor ke dalam database yang berada pada server.

Abstract

Diabetes Mellitus (DM) is one of the diseases with many patients in the world. The current method used by people with diabetes was an invasive approach using blood samples to monitor their blood glucose levels. The non-invasive approach that does not require blood samples would increase ease-of-use for diabetics. This research presents a microstrip antenna to monitor glucose levels in human blood non-invasively. The background concept of this approach was blood glucose variation causes variations of blood permittivity accordingly. This blood permittivity will affect the resonant frequency of the microstrip antenna. Antenna design and simulation were performed using CST Microwave Studio software. The antenna is designed on FR4 (εr = 4.3) dan NPC H220 (εr = 2.17) substrate with h = 1.6mm. A patch of microstrip antenna placed on one side and ground plane on another side, they are connected using SMA connector. The fabrication result of the designed antenna has an operating frequency of 2.17 GHz. In this research, the correlation between blood glucose and changing the microstrip antenna’s resonant frequency was observed. For this non- invasive method, the microstrip antenna is placed facing the forearm. Experimental results of both approaches, antenna placement with and without spacing to the forearm, show the shift of resonant frequency according to blood glucose changes. Based on this research’s linearity, accuracy, and sensitivity result, the microstrip antenna shows potential as a glucose- sensing device for a non-invasive method with further development.

Abstract

Tourism objects in the district of Nabire relatively not developed much and has not been handled optimally due to lack of promotion. E-Tourism which is an electronic application for the tourism sector that can facilitate the user to visit a tourist site at a location. The currently available apps can not make real-time data changes regarding the position of the app's user coordinates to find out where to find the sights. This study aims to provide information to application users about the position of the location of the tour and the position of users who can change in real-time using firebase. This research uses experimental method, that is pinned firebase platform on E-Tourism so that application can utilize various real-time database feature in firebase. The system is tested by moving the user's position of the app to see changes in position data in real-time and will be shown on the application map. The next test by showing the location of tourism as well as the path traveled by the user to reach the sights. The results of this study show the position of the user that can change in real-time when the user to switch position without having to refresh the data manually (refresh). Applications can also display a list of tourist sites and the path taken to get to the tourist sites located in Nabire district.

Abstract

E-learning is an information technology that has been widely applied to the field of education in the form of websites because it can be accessed indefinitely and place. The development of E-learrning is logical because it follows the age of putting forward information and communication technology. Conventional learning is especially an evaluation of essay form learning, where teachers check students' essay answers that require more time and effort. Automated Essay Scoring (AES) is one of the features of Elearning that can facilitate the teacher in matching the answer of student essay with answer key. Text similarity is a method of matching text that is recall word based on specified condition (term). The language used in AES is Indonesian which has a different word morphology with other languages. The results obtained in this study is the Error rate using the term frequency (tf) is lower with high accuracy.

Abstract

Smart   city mengacu pada konsep pengelolaan kota yang efisien, berkelanjutan, dan inovatif melalui pemanfaatan teknologi ICT terkini. Penggunaan sensor, big data, dan kecerdasan buatan (AI) memungkinkan pemantauan real-time terhadap lalu lintas, polusi udara, penggunaan energi, dan layanan publik lainnya. Tujuan utama dari konsep smart   city adalah meningkatkan kualitas hidup warga. Pada sisi lainnya, teknologi smart   campus adalah konsep yang mengintegrasikan teknologi ICT canggih ke dalam lingkungan universitas atau institusi pendidikan tinggi. Melalui teknologi smart   campus, pendidikan tinggi tidak lagi terbatas pada ruang kelas fisik konvensional. Penggunaan e-learning, aplikasi mobile, dan platform pembelajaran online memungkinkan mahasiswa untuk mengakses materi pelajaran kapan saja, dan di mana saja. Selain itu, teknologi ini juga dapat digunakan untuk meningkatkan pengalaman mahasiswa di luar kelas, seperti sistem manajemen informasi akademik yang terintegrasi, dan pusat kegiatan ekstrakurikuler yang terotomatisasi. Dalam rangka mendukung konsep smart   city dan smart   campus tersebut, Universitas Hasanuddin hadir memberikan solusi dan inovasi untuk menunjang proses belajar yang lebih inovatif dan atraktif di kampus.    Dengan berbagai peralatan smart   campus yang telah diriset, Universitas Hasanuddin juga mengajak perguruan tinggi lainnya untuk mulai beralih kedalam sistem smart   campus. Terdapat peningkatan pemahaman sekitar 67% dari peserta kegiatan bimbingan teknis dan pemutakhiran teknologi smart   campus yang berkolaborasi dengan pihak IAIN Bone. Data statistik ini mengkonfirmasi aspek urgensi kegiatan sejenis untuk secara berkelanjutan ditradisikan pada masa-masa yang akan datang.

Abstract

Radio Direction Finding (DF) and geolocation technologies are important for communication, modern navigation, and defense systems. While the foundational techniques have existed for over a century, they are increasingly challenged by modern electromagnetic environments. The growing complexity from signal multipath, widespread radio frequency interference (RFI), and the demand for higher precision strain the limits of these traditional methods. This paper provides a comprehensive review of the state-of-the-art in radio DF and geolocation, synthesizing recent scientific literature to map its evolution and current trajectory. This review also identifies the movement away from conventional, algorithm-based approaches and toward integrated, intelligent systems that dynamically adapt to their surrounding environments. Our systematic survey of recent literature from credible and updated databases identifies new technologies, key trends, and ongoing challenges in the field. The main finding is that the field is increasingly reliant on the synergistic fusion of advanced antenna architectures, hybrid multi-platform network configurations, and, most critically, artificial intelligence (AI) and machine learning (ML) to overcome the physical limitations of radio wave propagation. This synthesis highlights how AI is revolutionizing everything from spectrum sensing and RFI mitigation to signal classification and system optimization, paving the way for real-time, adaptive, and high-precision localization systems with a degree of robustness previously unattainable.
