Abstract

Kecamatan Dullah Selatan merupakan salah satu kecamatan yang berada di Kota Tual Provinsi Maluku dengan rata-rata pertumbuhan penduduk per tahunnya sebesar 3,5 % dengan jumlah penduduk pada akhir tahun 2018 sebesar 50.523 jiwa. Pelayanan air bersih di Kecamatan Dullah Selatan pada tahun 2018 sebesar 55% dari jumlah penduduk yang mana telah memanfaatkan sumber mata air Evu dengan debit 163 l/dt, sehingga memungkinkan untuk dilakukannya pengembangan jaringan distribusi air bersih guna memenuhi kebutuhan air bersih pada tahun yang akan datang. Dari hasil analisa diperoleh peningkatan pelayanan air bersih dari tahun 2018 sebesar 55 % menjadi 85 % pada tahun 2034 dimana peningkatan prosentase pelayanan tidak terlalu besar dikarenakan pertimbangan ketersediaan sumber air yang ada. Untuk rencana pengembangan sistem jaringan pipa menggunakan pipa berdiameter 150 mm dengan simulasi percobaan menggunakan program Watercad V8i didapatkan hasil simulasi yang memenuhi kontrol tekanan pada jam puncak. Selain itu harganya lebih ekonomis.

Abstract

Optimization of pipe diameter in the planning of clean water supply systems in Wonotirto District aims to determine the projected demand for clean water in Wonotirto District until 2028. This research was conducted because currently the distribution of clean water in the study location is still not completely fulfilled. Topographical conditions, most of which are in mountainous areas, cause one of the reasons for the difficulty of distributing clean water. The pipe diameter optimization planning in this study uses the Hazen-William method. The data used are the population in the last 10 years, geoelectric data, and topographic maps of Wonotirto District, Blitar Regency. Based on the results of the planning, it is found that the projected number of population in 2020 is 37,013 people. the discharge of clean water needs is 63.73 liters / second, the dimensions of reservoir 1 are planned to be 6 m x 4 m x 3 m, reservoir 2 is planned to be 6.5 m x 4 m x 3 m. The type of pipe used is the type of PVC with a diameter of 0.75 inches, 1 inch, 1.25 inches, 1.5 inches, 2 inches, 2.5 inches, 3 inches, 4 inches, 6 inches, where planning calculations are carried out using the Hazen-William Method. The limited amount of groundwater discharge at the location means that not all villages in the Wonotirto District area have their clean water needs met and it is hoped that further research will improve this research.

Abstract

Pertambahan jumlah penduduk tentunya menghasilkan pertambahan jumlah volume sampah organik dan anorgaik. Salah satu sampah yang dihasilkan masyarakat di Kelurahan Arjowinangun adalah sampah organik dan sampah anorganik, dimana sampah atau limbah organik dan limbah anorganik apabila tidak dilakukan pengolahan tentunya jumlah volume sampah akan semakin bertambah dan mengakibatkan terjadinya dampak pencemaran terhadap lingkungan, yaitu terjadinya penurunan sanitasi lingkungan. Berdasarkan kondisi eksisting maka permasalahan yang Kelurahan Arjowinangun adalah banyaknya tumpukan sampah aorganik dan sampah anorganik sehingga mengakibatkan terjadinya pencemaran lingkungan khususnya penurunan sanitasi lingkungan di sekitar permukiman dan terjadinya penyumbatan pada saluran drainase akibat masuknya sampah ke dalam saluran draianse. Oleh sebab itu dari permasalahan yang ada di lokasi mitra maka perlu dilakukan upaya mengurangi permasalahan pengurangan jumlah volume khususnya penanganan pemanfaatan sampah anorganik yaitu, salah satunya adalah pemanfaatan limbah botol plastik sebagai tambahan bahan konstruksi ringan sebagai pembuatan paving. Sehingga dari pemanfaatan limbah atau sampah anorganik yaitu limbah botol plastik maka diharapkan akan mengurangi jumlah volume sampah yang dibuang ke tempat pembuangan akhir sampah (TPA). Hasil dari pengolahan limbah botol plastik tersebut akan menghasilkan menjadi paving dan pendampingan mitra ini akan melibatkan masyarakat di Kelurahan Arjowinangun untuk memanfaatkan limbah botol plastik menjadi barang yang bernilai tinggi dan berguna serta berwawasan lingkungan.

Abstract

Fly ash based geopolymer concrete is an environmentally friendly alternative that can replace conventional Portland cement based concrete. This study aims to analyze the effect of the water cementitious (W/C) ratio on the compressive strength of Type C fly ash based geopolymer concrete from the Paiton Power Plant, as well as to determine the correlation between the water cementitious ratio and the concrete's compressive strength. The variations of the water cementitious ratio used were 0,35, 0,4, 0,45, 0,5, 0,55, 0,6, and 0,65. The alkaline activator used consisted of 8 M potassium hydroxide (KOH) and sodium silicate (Na₂SiO₃) with a ratio of 3:1. The test specimens, in the form of concrete cylinders (Ø15 cm × 30 cm), were tested at the ages of 3 and 7 days using the room temperature curing method. The results show that the compressive strength of the geopolymer concrete decreases with the increase of the water cementitious (W/C) ratio. At 3 days, the highest compressive strength of 28,42 MPa was achieved at a W/C of 0,35, while the lowest was 17,94 MPa at a W/C of 0,65. At 7 days, the highest compressive strength reached 37,13 MPa (W/C 0,35) and the lowest was 23,89 MPa (W/C 0,65). The concrete slump value increased with the increase in the W/C ratio, with the highest value of 18,4 cm at a W/C of 0,65. The test results conclude that the water cementitious (W/C) ratios of 0,35, 0,4, 0,45, 0,5, 0,55, 0,6, and 0,65 have a significant effect on the compressive strength of geopolymer concrete, where a higher water cementitious (W/C) ratio results in lower compressive strength.

Abstract

Biopori is a simple technology that can do a lot. This can be used as water absorption, reducing waterlogging, as a composting container, and of course fertilizing the soil. This program is run through a learning by doing system that uses material modules as teaching media. Based on the existing conditions, the counseling technique was carried out by gathering several local residents and providing direct practical explanations on how to install biopores and explaining the advantages of biopores as a means of storing water absorption as well as a composting medium for organic waste. The aim of this service is to master the technique of making biopores and prove the benefits of biopores in being able to overcome puddles while storing water reserves in the soil and can also be used as a composter for organic waste which can later be used as compost. So that the inconvenience of passing residents, especially those going to the mosque for worship, because there is standing water in the paving area of the mosque and reducing the volume of residents' waste, especially organic waste, can be resolved.
