Water is source of life on earth. The largest water body is in the ocean at 97 percent and 3 percent remaining is fresh water which is used to support daily needs, so clean water is a basic human need. The limited amount of water and increasing people number caused a clean water crisis. Apart from the amount, the quality of fresh water is getting worse. The struggle to use clean water for various uses and clean water wasteful behavior had resulted in the loss of adequate access of clean water for some people. One of the ways to improve clean water quality and quantity is conducting a water purification process. Water purification can be done using simple tools with filtration techniques. Through the Community Partnership Program’s theme "Education of Simple Water Purification as an Effort to Fulfill Clean Water Needs" able to provide knowledge and understanding to teachers and students of MTs Nurul Qur'an Jakarta as activity partners.

Abstrak SMK Ad Da’wah yang terletak di Kelurahan Duri Kosambi Kecamatan Cengkareng Jakarta Barat merupakan sekolah yang terkena dampak gempa bumi Banten 2018. Setelah peristiwa gempa bumi di bulan Januari 2018, sekolah belum memberikan pelatihan maupun sosialisasi tentang bagaimana langkah-langkah yang harus dilakukan apabila terjadi gempa bumi dan belum mengintegrasikan mengenai materi kesiapsiagaan bencana gempa bumi kedalam mata pelajaran. Kegiatan edukasi dilakukan dengan metode penyuluhan dan demonstrasi evakuasi gempa bumi oleh tim dan siswa-siswi SMK AD’Da’wah. Narasumber berasal dari Jurusan Teknik Sipil STT PLN Duri Kosambi, Kecamatan Cengkareng, Jakarta Barat, serta dukungan  perangkat sekolah SMK AD’-Da’wah. Dana pendukung dari institusi STT-PLN merupakan aspek penting terselenggaranya kegiatan PKM ini. Manfaat yang diperoleh dari kegiatan PKM ini antara lain SMK Ad-Da’wah memahami arti pentingnya kesiapsiagaan terhadap bencana gempa bumi sehingga dapat mengurangi korban jiwa dan kerusakan yang ditimbulkan akibat bencana gempa bumi. Kata kunci: Gempa Bumi, Evakuasi, Korban Jiwa

Paving block is a building material made of cement, water, and fine aggregate used as an alternative cover or hardening for land surface. It is commonly used for various purposes such as, sidewalks, parking lots, and road pavement. The increasing demand of cement-forming materials is due to the rise in the number of cement users, therefore, an environmentally friendly material is needed to be produced from industrial waste. Generally, Indonesia has extensive oil palm plantations, as a result, excess wastes are produced from the burning of oil palm shells namely, boiler scale ash (contains silica oxides (SiO2), pozzolan, and other compounds present in cement). Smelting and metal refining industries produce wastes from Granulated Blast Furnace Slag (GBFS), which contains silica oxide as their major chemical composition. Therefore, this study aims to determine the compressive strength and the water absorbing capacity of paving blocks using 10% of Palm Boiler Crust Ash as a substitute for fine aggregate/sand, and the percentage variations of Granulated Blast Furnace Slag (GBFS) waste as a cement replacement material. The results showed that the paving block variation V2 had the highest compressive strength (22.83 MPa), while the highest water absorption (5.45%) was found in variation V1, which was higher than the normal paving block (2.39%).

The impact of RAP on water was identified to be analyzed for the material's resistance to water because there are still a lot of waterlogged pavements in Indonesia. This research uses RAP variation 0%, 25% and 35%. The test is the Marshall test to get the optimum asphalt content value, the Cantabro test to determine the weight loss for 300 rounds and the durability by varying the immersion 0.1, 2, 4 and 7 days which will be tested for ITS. The KAO value obtained for each variation is 5.4% for 0% Rap, 5.6 for 25% Rap and 6% for 35% RAP. The results of the Cantabro test show that the largest percentage of weight loss is a mixture of 35% RAP which is 12.54%, where for 0% RAP there is a weight loss of 10.85% and at 25% RAP there is a weight loss of 11.66%. ITS test results have the highest value with variations of RAP 0%, RAP 25% and RAP 35%. variations of 0%, 25% and 35% showed a decreasing trend until the 7th day of immersion, it can be said that in the three variations the ITS value was influenced by the duration of continuous immersion.
