Abstract

Banjir merupakan bencana alam yang kerap melanda wilayah urban di Indonesia, khususnya daerah yang memiliki sistem drainase yang kurang optimal. Salah satu wilayah terdampak adalah Perumahan Masnaga Bintara Jaya, yang mengalami beberapa kejadian banjir selama periode musim hujan. Untuk mengatasi hal tersebut, penelitian ini bertujuan merancang sistem peringatan dini banjir berbasis Internet of Things (IoT) yang terintegrasi dengan algoritma Fuzzy Logic tipe Mamdani guna memberikan informasi secara real-time dan adaptif terhadap perubahan ketinggian air. Perancangan sistem dilakukan menggunakan sensor ultrasonik JSN-SR04T untuk mengukur ketinggian air, mikrokontroler NodeMCU ESP8266 sebagai pengolah dan pengirim data, serta platform ThingSpeak sebagai media penyimpanan dan visualisasi data. Data yang diperoleh diklasifikasikan ke dalam tingkat risiko menggunakan logika fuzzy, dengan kategori status “Aman”, “Siaga”, dan “Bahaya”. Hasil klasifikasi tersebut ditampilkan melalui website monitoring yang dapat diakses masyarakat secara langsung untuk mendukung kesiapsiagaan. Penelitian menggunakan metode prototipe dan diuji pada lokasi nyata dengan tujuan mengevaluasi kecepatan sistem dalam merespons kenaikan muka air serta akurasi klasifikasi risiko. Hasil pengujian menunjukkan sistem mampu mendeteksi dan memberikan notifikasi secara cepat dan tepat. Dengan pendekatan ini, masyarakat dapat mengambil tindakan lebih dini, sehingga risiko kerusakan dan korban dapat diminimalisir

Abstract

Avocado (Persea americana) is a horticultural commodity with high economic value but is climacteric, so the ripening process occurs quickly after harvest. Determining the ripeness level is still done conventionally (visually and manually) often results in subjective assessments and damages the fruit. This study aims to develop a non-destructive avocado ripeness identification system (unripe, ripe, and overripe) using the Adaptive Neuro Fuzzy Inference System (ANFIS) algorithm. The input parameters used are based on the Red-Green-Blue (RGB) color features and Gray Level Co-occurrence Matrix (GLCM) texture features extracted from digital images of avocados. The test results show that the combination of the ANFIS network architecture with a Gaussian membership function is able to recognize the ripeness level of avocados with an accuracy of up to 93.3% on the test data. This system is expected to be a technological solution for farmers and distributors in the process of sorting fruit objectively and quickly.

Abstract

The administration of justice in Religious Courts faces inefficiencies due to manual case classification and unpredictable resolution timelines. This research addresses the gap in systemic judicial management tools by proposing a hybrid machine learning architecture. The objective is to design a systemic information model integrating Deep Learning for case type classification and Ensemble Learning for duration prediction. The method employs CRISP-DM framework combining Long Short-Term Memory (LSTM) for text analysis and XGBoost for temporal regression on 4,461 case records from Bekasi Religious Court. Results indicate a classification accuracy of 93.9% and a Mean Absolute Error (MAE) of 12.4 days for duration prediction. The novelty lies in the systemic integration of dual predictive models into judicial workflows, proposing a digital transformation model for court administration. Conclusions affirm that hybrid AI systems significantly enhance resource planning and administrative efficiency

Abstract

The rapid growth of population and urbanization in Bekasi District has increased the demand for adequate road infrastructure, but it has also posed challenges in the maintenance and repair of existing infrastructure. The main constraint in addressing this issue is the limited available budget, although the Bekasi District Government has tried various innovative programs. In this context, it is important to have mechanisms that allow the public to report infrastructure problems quickly and accurately. Based on preliminary studies, many factors can cause road infrastructure damage. The aim of this research is to design and develop a Road Infrastructure Damage Complaint System in Bekasi District, providing easy access for the public to report road infrastructure damage and enabling authorities to prioritize infrastructure repairs more quickly and accurately, thus improving the quality of life for the community and building a complaint system that can help expedite the repair process.

Abstract

Pada setiap satuan pendidikan mempunyai tujuan agar dapat menghasilkan lulusan yang berkualitas dan berkompeten, perguruan tinggi juga perlu menjamin agar lulusan tersebut dapat diakui didunia kerja demikian halnya dengan Fakultas Psikologi Universitas Bhayangkara Jakarta Raya. Perancangan aplikasi pengelolaan kurikulum perkuliahan merupakan salah satu cara untuk membantu dalam pengorganisiran pengelolaan kurikulum di Fakultas Psikologi Universitas Bhayangkara Jakarta Raya dan diharapkan aplikasi pengelolaan kurikulum tersebut mampu membantu meminimalisir human error. Metode First In First Out (FIFO) dipilih karena metode ini memiliki cara mengatur dan menambahkan data relative terhadap waktu dan prioritas dimana bahwa metode tersebut menggambarkan prinsip teknik pengelolaan antrean dalam perancangan kurikulum, dalam hal ini metode tersebut memiliki kinerja media penyimpanan dimana informasi yang pertama kali dikirim adalah informasi yang pertama kali diterima dengan kata lain bahwa dalam proses perencanaan kurikulum yang pertama kali dikelola maka kurikulum tersebut pula yang pertama kali selesai. Hasil perancangan aplikasi pengelolaan kurikulum perkuliahan dengan menggunakan metode FIFO adalah pengelolaan data hasil laporan distribusi matakuliah dapat kembali di review dan dijadikan arsip prodi dalam evaluasi kurikulum selanjutnya, aplikasi pengelolaan kurikulum perkuliahan yang menggunakan metode Fifo dapat menjadi lebih terorganisir dalam penggunaan atau penerapan kurikulum pada Prodi Psikologi.

Abstract

The dissemination of information regarding cultural events in Bekasi City has not yet been fully optimized, resulting in uneven public participation across various cultural activities. This issue arises from the absence of a recommendation system capable of suggesting cultural events based on users' interests and preferences. This study aims to implement the User-Based Collaborative Filtering algorithm with the Pearson Correlation approach in a web-based cultural event recommendation system. The research methodology involved observation, interviews, and the collection of user rating data from 100 respondents, with the sample size determined using the Slovin formula. The recommendation process was carried out by calculating the average rating of each user, measuring the similarity between users using the Pearson Correlation coefficient, and predicting ratings for events that had not yet been evaluated by the target user. The results demonstrate that the proposed system is capable of identifying similarities in user preferences and generating personalized event recommendations that align with users' interests. In the case study, the predicted rating for User1 on the Pesta Nada event was 3.76, indicating a high likelihood that the event would be of interest to the user and therefore suitable for recommendation. The implementation of this recommendation system is expected to assist the public in discovering cultural events that match their preferences while supporting the Bekasi City Tourism and Culture Office in disseminating event information more effectively, thereby increasing public participation in cultural activities.
