Sam'ani — 2025-11-10

Fire is a disaster that can cause significant material and non-material losses. Delays in detecting early signs of fire often result in the rapid spread of flames and greater damage. This study aims to implement an early fire detection and warning system based on the AVR ATmega16 microcontroller, utilizing the LM35 sensor for temperature detection, the Flame V2 sensor for flame detection, and an SMS Gateway via a Wavecom modem as a medium for remote notification. The research adopts a prototype development approach, encompassing the stages of design, implementation, and system testing. The system is designed to provide two forms of alerts: a local audio alarm and a short message service (SMS) notification to registered user mobile numbers.

System testing was conducted using the black box method to validate the functionality of both hardware and software. Experimental results indicate that the LM35 sensor successfully detected temperature increases above 39°C, while the Flame V2 sensor accurately identified the presence of fire. The system automatically transmitted SMS notifications to the user and activated a buzzer alarm as a danger alert. Furthermore, users were able to control the activation and deactivation of sensors via SMS commands with specific formats, thereby enhancing the system’s operational flexibility. This study is expected to serve as a foundation for further development toward more intelligent, integrated, and adaptive fire detection systems.

Sistem Pendukung Keputusan Bantuan Rumah Tidak Layak Huni Berbasis Web Dengan Metode Simple Multi-Attribute Ratting Tehcnique Di Kota Palangka Raya

Haryadi — 2025-11-30

The issue of uninhabitable homes is a social problem encountered in both urban and rural areas. This has prompted the government to launch the Rumah Tidak Layak Huni (RTLH) program as an effort to help the community improve homes to become appropriate. However, this program has not yet been able to cover all uninhabitable homes, because the number of households living in uninhabitable homes is greater than the number of assistance packages available. To ensure the program reach the target, the government has established various requirements for prospective recipients of the assistance. The decision for a family with an uninhabitable home to receive assistance largely depends on how that decision is made. This study is research aimed at developing a web-based decision support system using the Simple Multi-Attribute Rating Technique (SMART) method for determining decisions on RTLH assistance recipients in Kota Palangka Raya. Based on observations and interviews in the field, seven criteria were obtained for recipients of RTLH assistance, namely the condition of the roof covering, frame, walls, doors/windows, floor, foundation, and sanitation, each of which has a certain weight. These alternatives are rated from 1 to 4, depending on the level of damage. With the SMART method implemented in the form of a web application, the results show that the system produced not only provides accurate results but is also easy for officers to use in the field.
