Abstract

Concrete is a building which is composed by an aggregate (sand rocks), cement and water (plus the other ingredients can be additive or admixture). Much research has been done on the concrete technology to meet the needs in infrastructure development started from the street, buildings, bridges, etc. The more concrete and more widespread use of the increasing scale of development also shows the more concrete needs in the foreseeable future, thus affecting the development of concrete technology which will demand new innovations regarding the concrete itself The times in the era of globalization, this resulted in a rapid increase of the number of goods waste residu which existence can be a problem for life, one of which is the presence of household glass waste. In this regard the efforts made are the utilization of powder glass as fine aggregate additive to enhance strong press concrete. Glass powder is used as a supplement for is smooth, with the addition of different variations, it is hoped to provide strong value press the concrete which is more varied and can be determined the  optimum levels of glass powder. As for the variation of the addition of powder glass used is 0 %, 25 %, 50 %, 75 %, and 100 %, with tests on a 3-day, 7-day, 14-day and 28 days. The result shows that glass powder can increase the strength of the concrete of compressive strength of concrete press 12 % normal, whereas for the optimum proportion is 25%.

Abstract

Every day, family residential neighborhoods discard the waste water that should be stored and processed. Most of waste water management system still does not meet the health requirements, it still use local waste water treatment systems (on-site) like septic tanks, because central wastewater treatment (sewage) is still not widely available in Indonesia. The local system does not require a huge cost when compared to a centralized system. Implementation and operation of the local system is more simply. Problems frequently encountered on the local system : the capacity and dimensions of septic tank does not fit requirements; effluent and influent not specification, there is no air pipes; channel infiltration does not performed percolation tests, the location of infiltration is too close with shallow wells; the slope of the bottom of the tank is not enough and only with one room at a time so that when suck the mud will be smelled. Need for septic tank construction planning, use of materials and determination of the true capacity of the septic tank. Also planning further treatment of septic tank with a leach field using channel permeation or infiltration wells. After calculation based Planning Procedures Septic Tank With Infiltration System SNI: 03-2398-2002 by way of calculation, capacity and dimensions are smaller than the septic tank by way of the table. After that, drawing plan should be made complete and detailed.

Abstract

Aspek topografi merupakan salah satu faktor penting dalam perencanaan galian dan timbunan.  Mengingat perlunya dipertimbangkan aspek topografi yaitu faktor ketinggian permukaan dari muka laut dalam perencanaan jalan maka perlu ditemukan suatu metode untuk memudahkan penentuan ketinggian permukaan tanah dari muka laut.  Pengukuran ketinggian yang dilakukan secara manual tentunya membutuhkan biaya dan waktu yang sangat besar.  Untuk itu perlu dilakukan suatu penelitian yang menganalisis ketinggian secara spasial menggunakan metode penginderaan jauh dengan memanfaatkan citra Digital Elevation Model (DEM) SRTM (Shuttle Radar Topography Mission), sehingga didapatkan klasifikasi ketinggian yang dapat dipergunakan sebagai dasar dalam perencanaan jalan.  Metode yang digunakan dalam pengklasifikasian ketinggian adalah metode intrpolasi dari hasil overlay peta ruang terbuka dengan citra DEMSRTM.  Dari hasil analisis didapatkan persentase perbandingan hasil klasifikasi ketinggian terhadap kontur adalah 9,359 % dan terhadap topografi adalah 8,139 %, hal ini menunjukkan bahwa metode interpolasi dapat digunakan dalam pengklasifikasian ketinggian dengan menggunakan peta DEMSRTM.

Abstract

Dewasa ini perkembangan beton sangat pesat, sehingga kriteria mengenai beton juga berubah sesuai dengan perkembangan jaman dan kemajuan tingkat mutu beton yang dapat dicapai. Karena itu banyak sekali bangunan yang menggunakan beton sebagai bahan utamanya, apalagi bangunan tingkat tinggi atau bangunan yang mempunyai bentang lebar akan membutuhkan beton yang mempunyai kekuatan tekan yang tinggi.  Kekuatan tekan beton dipengaruhi oleh kualitas bahan pembentuknya, kepadatan dan rasio air semen, sehingga pengaruh kadar air dalam pembuatan beton mutu tinggi sangat penting. Dengan demikian menggunakan bahan tambah Superplasitcizer yang dapat mengurangi penggunaan air diharapkan meningkatkan kekuatan tekan beton tetapi memudahkan dalam pekerjaannya.Penggunaan bahan tambah mineral ( additive ) untuk mendapatkan beton mutu tinggi saat ini sudah merupakan bahan yang penting. Bahan tambah mineral merupakan bahan tambah yang mengandung pozzollan. Pozzollan adalah bahan tambah yang kandungan utama silika dan alumina . Abu sekam padi yang mempunyai kandungan silika yang tinggi dapat dimasukkan sebagai  pozzollan.Penelitian ini dilakukan untuk mengetahui pengaruh penambahan abu sekam padi sebagai pengganti sebagian semen terhadap kuat tekan dan kuat tarik beton mutu  K – 500 . Dalam penetilian ini persentase pemakaian abu sekam padi sebesar  2,5 % ; 5% ; 7,5 % dan 10 % terhadap semen. Benda uji beton berbentuk kubus berukuran ( 15x15x15 ) cm untuk kuat tekan dan benda uji berbentuk silinder berukuran diameter 15 cm dan tinggi 30 cm digunakan untuk uji kuat tarik belah .Dari hasil pengujian didapatkan hasil bahwa kuat tekan dan kuat tarik pada beton yang menggunakan abu sekan padi kekuatannya meningkat bila dibandingkan dengan beton normal ( beton tanpa abu sekam padi ).

Abstract

Suatu lembaga pendidikan yang modern, harus didukung oleh sarana dan fasilitas yang dapat menunjang segala aktivitas yang berlangsung di dalam kampus, termasuk tersedianya sarana jaringan dan penyediaan air bersih yang memadai. Pendistribusian air bersih tentunya juga harus merata baik debit maupun tekanannya, karena itu diperlukan suatu sistem pendistribuaian yang handal sehingga dapat menjamin tersedianya air setiap saat dengan debit dan tekanan yang memadai. Politeknik Negeri Sriwijaya mempunyai jaringan distribusi air bersih yang sudah berusia lebih dari 30 tahun, sementara pada saat ini beban pendistribusiannya jauh lebih besar dibandingkan dengan beban di saat berdirinya kampus politeknik di awal tahun delapanpuluhan. Mengingat jumlah civitas akademika pada saat ini jauh meningkat dibandingkan dengan awal berdirinya politeknik, diperlukan pengkajian ulang tentang beban pendistribusian pada jaringan pipa distribusi air bersih di dalam kampus. Untuk pengkajian beban pendistribusian air bersih tersebut dilakukan penelitian untuk mengetahui realita pemakaian air bersih serta pola konsumsinya. Penelitian dilakukan dengan mengambil empat gedung utama sebagai sample untuk mendapatkan data konsumsi air bersih. Data yang didapatkan diolah dan dianalisis sehingga hasilnya dapat mencerminkan pola konsumsi air bersih di kampus Politeknik Negeri Sriwijaya.
