Abstract

Alat pemantau lahar idealnya dipasang di daerah terpencil yang jauh dari pemukiman mendekati sumber aliran. Hal ini dimaksudkan agar penduduk di sekitar aliran memiliki cukup waktu untuk menyingkir jika akan terjadi banjir lahar. Masalah yang muncul, di daerah terpencil tidak ada infrastruktur sumber daya listrik untuk memberi daya alat pemantau dan infrastruktur komunikasi dari alat pemantau ke pusat pemantauan yang jauh letaknya. Jaringan sensor nirkabel atau wireless sensor network (WSN) yang autonomous, real time, kompak dan hemat energi merupakan pilihan yang tepat untuk pemantauan di daerah terpencil seperti halnya pada pemantauan lahar dingin. Dengan pemilihan topologi yang sesuai dan ujung depan sensor yang tepat dan akurat dapat mendukung dibangunnya sistem peringatan dini banjir lahar dingin yang murah namun handal. Kombinasi sensor kedalaman aliran dan sensor tekanan fluida digunakan mendeteksi material alir yang dapat berupa air atau lahar. Percobaan dilakukan untuk memperoleh data kedalaman aliran dan tekanan fluida sehingga menghasilkan dua persamaan regresi untuk dua material alir tersebut, dengan harapan dapat digunakan untuk memberikan informasi material alir suatu sungai yang berhulu di gunung berapi.

Abstract

Sistem alarm perumahan yang umum biasanya mandiri, dirancang agar penghuni mengetahui jika terjadi sesuatu yang tidak beres dengan rumah tempat tinggal mereka. Misalnya, ketika terjadi pembukaan secara paksa pintu atau jendela, indikasi kebakaran, atau akses masuk area perumahan tanpa ijin. Sistem alarm mandiri seperti ini kebanyakan mengandalkan kewaspadaan penghuni rumah saja. Penghuni perumahan yang lain atau petugas keamanan mungkin saja tidak dapat memantau tanda bahaya ini jika letak rumah jauh dari jangkauan pandangan dan pendengaran. Terlebih, jika perumahan tersebut menempati area yang luas. Sistem alarm terpusat memberikan kemudahan pemantauan bagi petugas keamanan. Jaringan sensor nirkabel dapat dimanfaatkan untuk mewujudkan sistem alarm terpusat. Pengumpul data dan penampil berupa komputer pribadi dapat ditempatkan di suatu pos penjagaan yang biasanya terletak di bagian depan atau dekat dengan gerbang masuk area perumahan. Tanda bahaya dapat diwujudkan dengan alert atau peringatan yang muncul di monitor komputer, disertai bunyi-bunyian.

Abstract

With the increasing population and the reduction of water catchment areas due to numerous development projects that disregard green open spaces, coupled with a lack of public awareness regarding the importance of water flow, many individuals continue to consciously dispose of garbage into rivers, including river areas, dams, and reservoirs. This behavior leads to river blockages, resulting in flooding in those areas and other low-lying regions. The traditional method of monitoring water levels heavily relies on human operators, which can introduce errors when interpreting water indicators. To address these challenges, this research adopts a design-oriented methodology to develop an automated system for real-time maintenance and monitoring of water levels. The study begins with a comprehensive analysis of the existing issues and the underlying processes involved. Subsequently, the research focuses on designing and implementing a prototype system using appropriate materials, system development tools, and methodologies. The proposed system consists of a water level detection device integrated with a servo-controlled dam opener. Experimental tests demonstrate the device's effectiveness in accurately detecting changes in water levels, with an average accuracy of 10 cm from the sensor point. Additionally, the servo-controlled dam opener plays a significant role in regulating water flow within the system. The proposed system aims to facilitate efficient monitoring and decision-making processes, thereby reducing the occurrence of human errors in determining water levels.

Abstract

Along with the increasing times and the more busyness of humans, drying problems often become a very troublesome problem because it is still conventional by using direct sunlight. For example, when the crackers are drying, rain falls when the workers are doing other work. Of course the workers will feel anxious if the crackers that have been dried in the sun are wet with rain and have to be redried, so this research proposes to help the workers drying the crackers. This research will discuss the workings of the rain sensor, LDR (Light Dependent Resistor) sensor and heat / temperature sensor for drying crackers with the Arduino Uno system. This study aims to make a prototype cracker drying device that can automatically open or close the protective tarp for the cracker drying rack when it rains or the sun's light intensity has darkened using the Arduino Uno microcontroller. The design of this application uses the method prototype and uses the DELPHI programming language by utilizing the Arduino IDE and using the Microsoft Access database. The results of this study were obtained in the form of an automatic cracker drying tool application that can detect weather conditions during drying well. This tool will help the drying process from the beginning of drying until the crackers are completely dry and ready to be marketed.
