Garbage is a household product, which is produced every day. The household garbage becomes a big problem, if it can not be handled properly. Residents of RT 04 RW 09 Binawidya, Tampan district, city of Pekanbaru have experienced problems with waste such as unpleasant odors due to the accumulation of house yard waste before being disposed to a final disposal site. To reduce this problem, there are many solutions that can be done. One of them is to utilize organic waste from household, which is processed into Eco-Enzyme. The eco-enzymes made from household waste such as vegetable residues and fruit peels. It can produce environmentally friendly products such as floor cleaners, plant fertilizers, water purifiers and others. The eco-enzyme is very easy to make. The ingredients are used organic waste (vegetables and fruit peels), sugar and water in a ratio of 3:1:10. This paper explained the eco-enzyme production training that was given to housewives, aiming to use the waste produced by their households into useful products.
Beton porous merupakan beton khusus yang memiliki porositas tinggi yang memungkinkan air hujan dan sumber air lainya mengalir sehinga mengurangi lipasan atau air mengenang di permukaan. Beton porous diaplikasikan pada bidang datar. Pengaruh pengurangan air 0 %, 5 % dan 10 % dari Faktor Air Semen (FAS) 0,31 pada beton porous dengan bahan tambah superplastisizer sikament LN dosis 0,6 % dari berat semen. Agregat kasar yang digunakan berupa batu pecah (split) 10 - 20 mm. Pembuatan benda uji menggunakan silinder dengan diameter 15 cm dan tinggi 30 cm untuk pengujian kuat tekan. Pengujian porositas menggunakan sampel balok ukuran alas 10 cm x 10 cm, tinggi 15 cm. Sebelum pengujian dilakukan perawatan 14 hari dan 28 hari didalam air. Peningkatan kuat tekan optimum terjadi pada variasi pengurangan FAS 5 % dengan kuat tekan 12,64 MPa. Sedangkan porositas optimum pada pengurangan FAS 10 % yaitu 12, 62 %.
Pembangunan pada era saat ini berkembang dengan begitu cepat sejalan dengan pertumbuhan ekonomi. Pembangunan bangunan gedung khususnya mulai banyak dikembangkan sesuai dengan kebutuhan pasar pada saat ini. Kekurangan luas lahan menjadi alasan pemilik bangunan melakukan pengembangan arah vertikal (bertingkat). Penggunaan material yang digunakan juga harus diperhatikan terutama akan berpengaruh pada bobot bangunan. Semakin berat bobot bangunan maka dimensi penampang dan tulangan yang digunakan juga akan semakin besar. Salah satu solusi dalam mengurangi bobot bangunan adalah dengan penggunaan bata ringan Ultra Light Concrete (ULC) yang terbuat dari material semen, pasir pasang, gypsum dan air. Dalam penelitian ini dilakukan pengujian bata ringan ULC dengan menggunakan 3 jenis variasi persentase penggunaan katalis yaitu 0,5% ; 0,6% dan 0,7% dari berat volume material penyusun adukan dengan menggunakan pasir pasang kulim di Pekanbaru, setiap persentase terdapat 3 benda uji dan diuji pada umur 28 hari. Berdasarkan hasil pengujian maka dihasilkan kuat tekan rata-rata pada persentase 0,5% menghasilkan kuat tekan 0,64 MPa, persentase 0,6% menghasilkan kuat tekan 0,36 MPa dan persentase 0,7% menghasilkan kuat tekan 0,54 MPa. Berdasarkan dari pengujian kuat tekan dari tiga jenis persentase penggunaan katalis tersebut maka persentase yang paling optimal adalah persentase 0,5% dengan kuat tekan 0,64 MPa.
Pekanbaru City is a metropolitan city with a very dense traffic volume with a low level of discipline for road users. Violations of traffic signs often occur and a sense of care to comply with traffic regulations is still low, accidents often occur. As a result of undisciplined road users, it creates anxiety and worries about accidents. For this reason, it is necessary to conduct traffic safety education. Traffic counseling should be taught from an early age, where children are able to provide an understanding of good behavior in order to form a disciplined child character. The teaching method is adjusted to the age where the Shalsabila PAUD children are aged 2.5 - 5 years which is included in the category of Toddler and preschool age. The method used is made fun by telling stories, singing and playing. So they are very enthusiastic and happy. Most preschoolers begin to understand and can distinguish what can be done and what can't be done.
