Paving block merupakan material penutup atau pengerasan permukaan tanah yang sangat luas penggunaannya terutama untuk trotoar jalan, pengerasan jalan kawasan pemukiman, memperindah taman, pengerasan area parkir dan lain sebagainya. Paving block dalam tinjauan ini adalah paving block yang dihasilkan dari pencampuran air, semen, pasir, limbah abu pembakaran sampah non organik sebagai pengganti sebagian pasir. Selama ini abu pembakaran sampah non organik belum banyak dimanfaatkan, bahkan dibuang begitu saja tanpa adanya pengolahan yang lebih bermanfaat sehingga menumpuk dan terkesan hanya mengotori lingkungan sekitarnya. Penelitian ini bertujuan untuk mengetahui kekuatan tekan paving block bila pasirnya digantikan dengan limbah abu pembakaran sampah non organik menggunakan prosentase tertentu. Metode Penelitian dilakukan secara eksperimental di laboratorium dengan dua tahap pengujian. Pada tahap awal penelitian dilakukan pengujian pendahuluan meliputi pengujian sifat fisik bahan. Tahap kedua dilakukan pembuatan benda uji menggunakan limbah abu pembakaran sampah non organik sebagai subsitusi pasir dengan prosentase abu 0%, 10%, 20% dan 30% dari berat pasir kemudian dilakukan uji tekan pada umur 7, 14 dan 28 hari. Dari hasil pengujian, didapat hasil kuat tekan paving block menggunakan limbah abu pembakaran sampah masing-masing adalah 16 MPa, 17 MPa, 15 MPa dan 11 MPa. Berdasarkan hasil penelitian dapat disimpulkan bahwa kenaikan kuat tekan terbesar pada paving blok menggunakan campuran abu pembakaran sampah anorganik berada pada prosentase abu 10% dan terjadi penurunan kuat tekan pada paving block dengan persentase abu 30%. Hal tersebut menunjukan, bahwa kita dapat menggunakan abu sisa pembakaran sampah anorganik sebagai salah satu alternatif material konstruksi ramah lingkungan.

AbstractIncreased housing construction has resulted in an increased demand for concrete beams, this of course has an impact on the needs of basic materials such as sand. The increasing demand for sand will have an impact on the price of sand, especially for areas that are difficult to get sand as raw material. An alternative to sand is to use basic ash. This waste will accumulate and pollute the environment. One effort to reduce this waste was to make glass waste as a substitute for cement in bricks. This study aimed at determining the compressive strength of concrete beams using bottom ash and cement with glass waste in a certain percentage. This research was carried out in two testing stages. In the initial stage of the study, the preliminary phase carried out included the physical properties of the material testing. The second step was to make test specimens with four variations of the mixture, that was 0%, 10 % LK + 10 % BA, 10 % LK + 20 % BA dan 10% LK + 30 % BA, and then a compression test on 7, 14 and 28 days of age. From the test results, the compressive strength results obtained from the brick using bottom ash and glass waste were respectively 4,13 MPa, 4,31 MPa, 7,14 MPa dan 5,21 Mpa. Based on the results of the research (no subject of the sentence) we concluded that the most increased compressive strength of the brick was on 10 % LK + 20 % BA variation, and the decrease of compressive strength started on 10 % LK + 30 % BA variation.Keywords : brick, residential, bottom ash, compressive strength, glass waste.AbstrakMeningkatnya pembangunan hunian mengakibatkan naiknya permintaan akan batako, hal ini tentunya berdampak terhadap kebutuhan bahan dasar batako seperti pasir juga mengalami peningkatan. Kebutuhan pasir yang meningkat akan menaikkan harga pasir, terutama untuk daerah yang sulit mendapatkan bahan baku pasir. Bahan alternatif pengganti bahan baku pasir salah satunya adalah dengan memanfaatkan limbah bottom ash. Selama ini limbah bottom ash hanya ditimbun di lahan kosong, sehingga menumpuk. Hal ini tentunya sangat berbahaya apabila bottom ash terbawa angin atau air karena dapat mencemari lingkungan serta mengganggu pernapasan. Limbah kaca merupakan salah satu limbah anorganik hingga saat ini. Limbah ini dibuang begitu saja tanpa adanya pengolahan yang lebih bermanfaat sehingga menumpuk dan terkesan hanya mengotori lingkungan sekitarnya. Salah satu upaya mengurangi limbah ini dengan menjadikan limbah kaca sebagai substitusi semen pada batako. Penelitian ini bertujuan untuk mengetahui kekuatan tekan batako bila pasirnya digantikan dengan limbah bottom ash dan semen digantikan dengan limbah kaca menggunakan prosentase tertentu. Penelitian dilakukan secara eksperimental di laboratorium dengan dua tahap pengujian. Pada tahap awal penelitian dilakukan pengujian pendahuluan meliputi pengujian sifat fisik bahan. Tahap kedua dilakukan pembuatan benda uji dengan dengan empat variasi campuran yaitu 0%, 10 % LK + 10 % BA, 10 % LK + 20 % BA dan 10% LK + 30 % BA kemudian dilakukan uji tekan pada umur 7, 14 dan 28 hari. Dari hasil pengujian, didapat hasil kuat tekan batako menggunakan limbah bottom ash dan limbah kaca masing-masing adalah 4,13 MPa, 4,31 MPa, 7,14 MPa dan 5,21 MPa. Berdasarkan hasil penelitian dapat disimpulkan bahwa kenaikan kuat tekan terbesar batako terdapat pada variasi 10 % LK + 20 % BA dan terjadi penurunan kuat tekan batako pada variasi 10 % LK + 30 % BA.Kata kunci : Batako, hunian, bottom ash, kuat tekan, limbah kaca.

Bamboo as construction materials can be used in house building, including columns, beams, partitions, horses, bridges as well as a buffer. The strength of a bamboo construction is influenced by the strength of the connections. At the assembly the construction of bamboo as construction of the horses, the connection with the bolt connector and plate make the horses construction of bamboo less economical because the cost of a bamboo construction will be expensive on the connection.The research is conducted experimentally in two phases of testing. In the early phase of research it is conducted preliminary testing which includes physical and mechanical properties testing of bamboo. The second phase at connection do testing compressive strength with a variety of angles namely 00, 450, and 900. The test results show the value of bamboo moisture content and density of each amount of 12.90% and 0.58 g/cm3. The Connection strength of obtained values theoretically are the lowest strength at 900 angle direction of the strength of 769 kg and the highest on the strength direction with angle of 00 amounting to 1732 kg while the value of the connection strength on the direction angle of 450 amounted to 889 kg. The greater the angle of direction of the force then minimize the connection strength.

Jakarta is one of area that often experiences in flooding. Jakarta is increasingly vulnerable being affected due to the limited catchment area. Massive development with water tight surface conditions and limited water absorption caused by about 85% of rainfall falls in the Jakarta area. As a result of lack absorption in Jakarta, the amount of rain falling and flowing into the sea and rivers will increase. When the capacity of the river does not cover the river water automatically overflows it will cause flooding. Mitra PKM is a junior high school building located in the Menteng area, Central Jakarta. In recent years the Mitra Area has overcome flooding disasters, the teaching and learning process in the Mitra region has being obstructed. The clean water crisis also occurs in the Mitra area, this is due to the location of the Mitra which is quite connected to office buildings that have a large enough need of clean water. The average rainfall in Indonesia is 2779 mm per year, in Jakarta around 2500 mm per year, with a total of 180 rainy days/year. According to average rainfall, is the potentially of water resources and it can be utilized optimally. Sources for water specifically rainwater resources by making infiltration wells. Infiltration wells work to collect surface water and then absorb the soil to become ground water reserves. Converting sufficient (surplus) ground water, will compensate for drought in the dry season in the form of water flow.
