<![CDATA[Dalam metode dan perumusan Saluran Drainase Porus oleh Sunjoto (1993), parameter yang digunakan untuk menentukan besarnya debit kehilangan air di saluran adalah tinggi air dalam saluran (m), koefisien permeabilitas tanah (m/s), lebar tengah saluran (m) dan panjang saluran. Adapun pada penelitian ini mencoba untuk mengembangkan metode dan perumusan tersebut dengan mengkaji apakah lama waktu pengaliran memiliki pengaruh terhadap besar peresapan yang terjadi pada saluran drainase porus. Penelitian dilakukan dengan memanfaatkan permodelan saluran draianse porus yang terdapat di Fakultas Teknik Unlam Banjarbaru. Data penunjang seperti data hidrologi dan sampel tanah diperoleh dari data proyek pembuatan model saluran drainase porus dan sumur resapan di Fakultas Teknik Unlam Banjarbaru. Dari hasil penelitian dapat disimpulkan bahwa fungsi waktu (lama waktu pengaliran), ternyata tidak mempengaruhi terhadap besarnya peresapan yang terjadi pada sebuah Saluran Drainase Porus. Sehingga formula yang dikemukakan oleh Sunjoto (1993) ternyata memang telah sesuai dengan aplikasinya di lapangan. Terbukti dari data debit rembesan (Q rembesan) yang terjadi pada 2 kali percobaan konstan sebesar Q = 3,82 l/d pada percobaan pertama dalam rentang waktu 9 menit dan Q = 3,84 l/d pada percobaan kedua dalam rentang waktu 15 menit]]>

<![CDATA[Penelitian mengenai Abu batubara (baik fly ash maupun bottom ash) telah banyak dilakukan khususnya pada bidang ilmu sipil bahkan pertanian. Pada bidang sipil, penelitian sering dilakukan pada sampel bata, batako dan beton. Adapun untuk bidang ilmu pertanian, sering dilakukan penelitian abu batubara sebagai campuran pupuk tanaman. Akan tetapi, kandungan oksida logam berat pada limbah abu batubara membuat limbah ini dikategorikan sebagai bahan berbahaya dan beracun (B3) pada PP Nomor 101 Tahun 2014 tentang pengelolaan limbah bahan berbahaya dan beracun. Berkaitan dengan hal tersebut, hasil penelitian uji potensi toxisitas yang telah dilakukan terhadap abu batubara PLTU asam-asam, membuktikan sebaliknya. Sebenarnya abu batubara PLTU Asam-Asam relatif aman untuk digunakan sebagai bahan konstruksi. Dari hasil tersebut, maka abu batubara PLTU Asam-Asam memiliki potensi yang cukup baik untuk dimanfaatkan. Salah satu potensi abu baubara di daerah rawa yang dapat dikembangkan adalah pemanfaatannya sebagai material konstruksi komposit yang padat seperti batako ataupun beton. Hasil penelitian ini menunjukkan bahwa dengan menggunakan rasio penggantian semen oleh fly ash sebesar 40% dapat meningkatkan kekuatan batako sebesar 3,5%. Sedangkan untuk hasil pengujian kuat tekan beton, penambahan fly ash sebesar 20% dapat meningkatkan kekuatan beton sebesar 16%. Berdasarkan dari hasil pengujian yang didapatkan, dapat diberikan rekomendasi pemanfaatan abu batubara di daerah rawa yaitu sebagai bahan campuran untuk pembuatan batako dan beton.]]>

<![CDATA[Claystone is rock contained generally of plastic, composed of a hydrous aluminum silicate (2H2OAL2O32SiO2) or fine grain size clay minerals. At the time of the construction of the Banjarbakula Regional TPA, there was found quite a lot of claystone material, of which there were more than 8000 m3 of claystone. Because they were not utilized properly, most of the claystone was removed and moved from the Banjarbakula Regional TPA. Therefore, it is necessary to reuse it, so the large amount of claystone material will not be wasted and can be optimally used. This study was conducted to determine the effect of claystone found in the Banjarbakula Regional TPA as an alternative to fine aggregate substitute for the quality of paving blocks and to determine the optimum mixture. In making paving block samples, variations of claystone were used as much as 0%, 25%, 50%, 75%, and 100% with water to cement ratio 0.4. The compressive strength test of paving block samples was carried out at the age of 7 and 28 days. Based on the results of the compressive strength test, the compressive strength value of paving blocks with 25% claystone mixture at the age of 28 days is 18.08 Mpa, which is the closest to the strength of normal paving blocks or without claystone mixtures of 18.24 MPa. The strength of a paving block with claystone mixture might increase with longer duration of the curing time.]]>

<![CDATA[Kerusakan pada jembatan biasanya terjadi akibat penurunan mutu material hingga adanya beban benturan pada struktur jembatan. Sehingga perlu dilakukan evaluasi kondisi jembatan tahap awal yaitu penilaian kondisi jembatan. Dilakukan evaluasi nilai kondisi Jembatan Girder Baja Komposit yang terletak di Kabupaten Tapin untuk mengetahui penanganan yang tepat baik untuk proses pemeliharaan, rehabilitasi, atau penggantian elemen jembatan yang rusak. Dua metode penilaian kondisi jembatan yang digunakan untuk evaluasi yaitu metode Bridge Management System (BMS) dan Bridge Condition Rating (BCR). Dari hasil penilaian kondisi, akan dihitung prediksi umur jembatan akibat kerusakan elemen. Berdasarkan hasil penilaian kondisi, diketahui bahwa jembatan memiliki nilai kondisi 2,42 untuk metode BMS dengan usulan perbaikan segera dan nilai kondisi 4,308 untuk metode BCR dengan usulan penanganan rehabilitasi dan tingkat kondisi sedang. Umur jembatan setelah dilakukan penilaian kondisi adalah 35,8 tahun berdasarkan BMS dan 33,9 tahun berdasarkan BCR. Sisa umur jembatan jika umur rencana jembatan 50 tahun adalah 16,1 tahun berdasarkan nilai kondisi BCR. Dari umur jembatan dan nilai kondisi jembatan juga diketahui bahwa jembatan memasuki fase perkembangan kerusakan dan memerlukan penanganan rehabilitasi.Kata kunci: nilai kondisi, umur, kerusakan, jembatan, BMS, BCR]]>

<![CDATA[Growth in residential, industrial, and office area,are significantly occurred in all city in Indonesia. Unfortunately, this is also caused more land that being covered by pavement and concrete in the cities. Realized or not it will disturb the availability of the groundwater and also lead to flooding in the rainy season. One of the effective solutions to solve this problem is by making sufficient numbers of infiltration well in the city, especially in the residential area. This research was conducted to analyze the ideal design of the infiltration well in the residential area. The design was made according to the equation by Sunjoto, which also refers to Indonesia standard (SNI) No: 03- 2453-2002. The results show that the ideal dimension for the infiltration well is to use the radius of the well (R) of 1.25 m. With the R of 1.25 will give a significant recharge to the groundwater as much as ≈ 2.400 liter. It is expected that this research encourage a development in the urban drainage systems which will consider the environment and the groundwater reservation for the balance of our ecosystem.]]>
