Abstract

ABSTRAKSebagian besar daerah di Indoensia, terutama Propinsi Bengkulu termasuk salah satu daerah yang rawan bencana longsor, karena sebagian besar wilayah ini dilalui oleh jalur patahan gempa yang cenderung menyebabkan kondisi tanah menjadi labil. Hal ini menyebabkan bencana longsor menjadi masalah yang perlu di waspadai oleh masyarakat khususnya yang berada di area topologi tanah yang labil. Pada penelitian ini sistem deteksi bencana longsor dirancang untuk dapat mengetahui kondisi pergerakkan tanah secara real time sebagai bagian dari sistem peringatan dini (early warning system) terhadap bahaya terjadinya longsor. Hasil pengujian menunjukkan bahwa sistem mendeteksi kondisi Bahaya dan mengirimkan SMS “Awas Longsor” pada nomor tujuan, saat tegangan sensor kelembaban tanah bernilai 3 V, sensor piezoelektrik bernilai 0,06V dan sensor accelerometer bernilai 1,574 V. Selanjutnya rancangan modul alat deteksi longsor juga menghasilkan delay waktu pengiriman SMS peringatan dini longsor pada sistem sekitar 5 detik dari hasil pengukuran sensor pada mikrokontroller.Kata kunci: deteksi longsor, kelembaban, piezoelektrik, accelerometer, sms ABSTRACTMost areas in Indonesia, especially Bengkulu Province, are one of the areas prone to landslides, because most of these areas are traversed by earthquake fault lines which tend to cause soil conditions to become unstable. This causes landslides to become a problem that needs to be alerted by the community, especially those in areas of unstable soil topology. In this study, a landslide detection system is designed to be able to determine the condition of ground movement in real time as part of an early warning system against the danger of landslides. The test results show that the system detects a "Bahaya" condition and sends an SMS "Awas Longsor" on the destination number, when the soil moisture sensor voltage is 3V, the piezoelectric sensor is 0.06V and the accelerometer sensor is 1.574 V. Furthermore, the design of the landslide detection module also produces a delay in sending SMS early warning landslides to the system about 5 seconds from the measurement results of sensors on the microcontroller.Keywords: landslide detection, humidity, piezoelectric, accelerometer, sms

Abstract

Bencana kebakaran yang menghanguskan rumah atau gedung semakin banyak terjadi terutama pada musim kemarau panjang yang selalu ada setiap tahun. Bencana kebakaran terburuk yang terjadi di jalan KZ Abidin Kelurahan Belakang Pondok Kota Bengkulu bulan November 2021 yang lalu mengakibatkan empat orang meninggal dengan kondisi tubuh hangus terbakar. Tingginya tingkat kejadian bencana kebakaran ini disebabkan oleh banyak faktor, diantaranya karena minimnya pengetahuan terhadap sistem deteksi kebakaran dan pemadaman otomatis yang bisa dirancang sendiri dengan teknologi yang sederhana. Pada penelitian ini sistem deteksi bencana kebakaran dirancang menggunakan sensor asap, sensor suhu dan sensor api sebagai komponen pendeteksi dengan menggunakan mikrokontroller sebagai control centre system untuk mengendalikan beberapa komponen pemadam secara otomatis. Selain itu, sistem deteksi bencana kebakaran yang dibangun juga akan mengukur dan menginformasikan data terkait bencana kebakaran sebelum dan sesudah secara real time kepada siapa saja yang telah terdaftar dalam database jaringan GSM control centre number melalui aplikasi whatsapp. Hasil dari penelitian adalah kinerja sensor asap (sensor MQ2) dapat diketahui bahwa nilai setpoint untuk mendeteksi keberadaan asap bernilai lebih dari 100 atau ketika tidak ada asap nilai sensor MQ2 yang terbaca oleh sensor dalam kisaran range 90-95.

Abstract

Bengkulu City is a region with a high risk of tsunami due to its location adjacent to the Indian Ocean and its position in an active subduction zone. The low level of public knowledge regarding disaster mitigation increases the potential for casualties in the event of a tsunami. This community service activity aimed to enhance the understanding, awareness, and preparedness of residents in Pagar Dewa Village, Selebar District, Bengkulu City, regarding tsunami hazards through mitigation-based education and socialization. The implementation methods included socialization (counseling), interactive discussion and dialogue, presentation of evacuation routes, and information on prevention and emergency response. The results showed a significant increase in public knowledge and preparedness, demonstrated by participants’ ability to recognize early tsunami signs and take appropriate evacuation actions. Residents also showed high enthusiasm and emphasized the importance of ongoing training to maintain mitigation awareness. This activity successfully built synergy between the university, local government, and the community in reducing disaster risks in coastal and lowland areas around Bengkulu City. Therefore, tsunami mitigation education is a strategic step toward creating a disaster-resilient community and strengthening readiness for future natural threats.
