Abstract

Kebocoran gas merupakan salah satu permasalahan yang sering muncul di beberapa bidang industri, hal ini membuat beberapa kecelakaan yang terjadi karena keberadaan gas yang tidak dapat terdeteksi secara kasat mata. Perkembangan mobile sensor menjadi salah satu cara untuk menanggulangi kerugian baik dari materiil maupun non materiil. Sensor LiDAR dan sensor gas merupakan jenis sensor yang dapat digunakan untuk mendeteksi gas. Pada Tugas Akhir ini, akan membahas bagaimana mendeteksi kebocoran gas pada suatu ruangan. Dibantu dengan metode SLAM sebagai navigasi dan gabungan metode source-seeking dan active-sensing localization sebagai pengidentifikasi titik-titik kebocoran, mobile sensor mengidentifikasi titik-titik kebocoran yang diambang batas normal. Setelah dilakukan finalisasi titik kebocoran gas, maka mobile sensor akan memberikan feedback kepada user. Target capaian dalam penulisan proposal ini yaitu bagaimana Mobile Sensor dapat mengidentifikasi titik-titik yang terindikasi adanya kebocoran gas dan bisa mengidentifikas nilai kebocoran dari titik tersebut. Dengan memanfaatkan sensor LiDAR dan sensor gas, diharapkan agar nilai yang didapatkan memiliki akurasi >85%. Kata kunci: SLAM, Mobile Sensor, source-seeking, dan active-sensing localization

Abstract

Missing and incomplete observations in Environmental IoT sensor networks reduce data reliability and disrupt analyses, especially for temperature and humidity time series exhibiting strong diurnal seasonality. This study develops and evaluates a seasonal imputation method to address missing data in IoT-based environmental monitoring, using a workflow of anomaly detection, outlier removal, time-of-day-aware imputation, and performance evaluation under varying missing-rate scenarios. Key challenges include sensor noise, connectivity issues, and intermittent hardware failures, which degrade data integrity and affect trend analysis, forecasting, and anomaly detection. To mitigate these, the method uses hourly and minute-level seasonal patterns after filtering out physically unrealistic values. Experimental results show high accuracy and robustness in reconstructing temperature and humidity data: temperature imputation achieves MAE values of approximately 0.86–0.87°C, and humidity yields MAE values of 3.92–4.01%RH, with no performance drop even at 50% data loss. The imputed series preserves natural diurnal dynamics without introducing distortions, effectively restoring continuity and structural consistency in environmental IoT time series for reliable modeling, feature extraction, and decision support.

Abstract

Background: Environmental security is essential for residential safety and quality of life. In RW 10, Kp. Ciganitri, Lengkong Village, Bojongsoang District, Bandung Regency, the existing conventional surveillance system has several blind spots, contributing to several theft incidents and estimated economic losses of approximately IDR 35,000,000. This community service program aims to strengthen community-based environmental security by integrating digital technology and citizen empowerment. Contribution: This program contributes to the community by strengthening environmental security, enhancing residents’ capacity to manage digital security technology, and fostering active community participation. Method: A participatory and collaborative approach was adopted involving residents and RW administrators. The program included blind-spot mapping, CCTV installation at strategic locations, integration of a remote monitoring system, preparation of standard operating procedures (SOPs), resident training, the establishment of a community security monitoring group, followed by monitoring and evaluation. Results: Four outdoor IP CCTV units were installed at strategic points (main gate, main road, and parking area) with standalone local storage, cloud backup, and real-time remote monitoring via a mobile application. A community security monitoring group was formed and residents were trained in system operation and incident reporting. A satisfaction survey of 20 residents showed that 100% agreed or strongly agreed that the program met community needs, was well implemented, and should be continued.. Conclusion: The integration of digitally-based CCTV with community empowerment effectively strengthened environmental security in RW 10, closing surveillance blind spots and increasing residents' sense of safety, while supporting SDG 9 and SDG 11 and providing a replicable model for other community-based digital security initiatives.
