Abstract

Geographical Information System technology (GIS) uses a document database (JSON) as an object that can be applied to geographic information systems using object data in the group of women farmers (KWT) in Lampung Province. The distribution of KWT in Lampung Province can be done using a geographic information system. The use of relational databases can be replaced by using the document database as a database on the distribution of KWT in Lampung Province. There are 3 data markers for example KWT in Lampung province using google maps. By using a JSON document as a document database as an object it is possible to serve as a geographic information system database.

Abstract

The watering of plants seeds could be carried out automatically by using technology development of Programmable Logic Controller (PLC). PLC is a control system that can be programmed in controlling and organizing the watering of plants seeds. It is also can be arranged according to the need of water in each step of seed growth until the plants completed mature. By using sensor to measure the water humidity and timing program to organize water pump in controlling watering process so that the seeds are not water accessed, therefore the seeds growth could be optimal. Kata Kunci:  PLC, penyiraman bibit tanaman

Abstract

The poor cellular signal strength subscription is one of major problem faced by most of the sub-districts in the Lampung province. Poor cellular signal strength subscription has a side effect in Internet transmission data processes both of transmit mode (Tx) and receives mode (Rx). To solve the problem that has been presented, this research proposed a new approach by utilizing Internet Infrastructure as a Service (IaaS) based on Cloud Computing to solve Internet data transmission problems. This research gets a conclusion that Cloud Computing-based Internet Infrastructure as a Service (IaaS) can convert a massive transmission data packets and break it down to a small transmission packet that can be transmitted or received through GSM-EDGE signal level.

Abstract

MVC dikembangkan untuk memetakan input, process, output. Web framework sangat cocok untuk pengembangan aplikasi berbasis web karena lebih fleksibel dan secure. Proses  bisnis  di  perguruan  tinggi  tidak akan lepas dari berbagai permasalahan, seperti manajemen projek yang kurang rapi, atau proses manajemen  lainnya,  informasi  yang  kurang  akurat dan responsi naskah atau dokumen menggunakan kertas,   apabila   dilakukan   berulang   maka   dapat memicu  pengeluaran  dana  yang  tidak  sedikit, pencarian   dokumen   hardcopy   dimasa   yang   akan datang juga sulit dilakukan karena tidak ada tempat penyimpanan  secara  elektronik.  Maka  untuk mengatasi permasalahan tersebut maka peneliti mengembangkan Kantor Digital berbasis framework dengan Metode Waterfall.

Abstract

Penelitian ini mengembangkan asisten akademik berbasis kecerdasan buatan multi-model yang memanfaatkan empat model bahasa besar (LLM) melalui platform OpenRouter API, meliputi Llama 3.3 70B, DeepSeek R1 Distill Llama 70B, Gemma 3 27B, dan Phi-4. Pengembangan sistem menggunakan metodologi Prototype SDLC dengan pendekatan iteratif. Evaluasi penerimaan pengguna dilakukan menggunakan Technology Acceptance Model (TAM) terhadap 30 responden mahasiswa Politeknik Negeri Lampung. Hasil penelitian menunjukkan nilai Perceived Usefulness (PU) sebesar 4,32, Perceived Ease of Use (PEOU) sebesar 4,18, dan Behavioral Intention to Use (BIU) sebesar 4,27, yang mengindikasikan tingkat penerimaan yang tinggi. Sistem mampu mengintegrasikan respons dari keempat model secara simultan dan menyajikan perbandingan hasil secara terstruktur, sehingga memberikan perspektif yang lebih komprehensif bagi mahasiswa dalam menyelesaikan tugas akademik.

Abstract

Rice is a staple food globally, yet its productivity is often threatened by diseases such as blast and brown spot. Traditional diagnostic methods relying on human observation are prone to delays and inaccuracies. This study introduces an automated detection system that utilizes YOLOv11-seg to improve the accuracy and efficiency of rice disease identification. The model integrates object detection and instance segmentation, is trained on over 6,000 annotated images covering six categories (five disease types and healthy leaves), and leverages transfer learning from COCO weights. Experimental results show that the model achieved a bounding box mAP@50 of 0.607 and a segmentation mAP@50 of 0.564, with F1-scores of 0.62 and 0.59, respectively. The highest detection accuracy was recorded for healthy leaves (86%), while segmentation performance declined on visually similar classes such as Brown Spot and Sheath Blight. Overfitting was observed during training, with a 15–20% gap between training and validation metrics. These findings demonstrate the model's potential for real-time field application in precision agriculture. Future improvements should focus on enhancing spatial accuracy and robustness through synthetic data generation and architectural optimization.
