Abstract

This research was conducted by using non-destructive test method and destructive test to investigatethe compressive strength of repaired concrete masonry wall with chemical additive sited at Sriwulan Village which is tidal flooding prone area and PucangGading Village. Non-destructive test using Hammer Test was conducted at age 12 months, 13 months, and 14 months after concrete masonry wall being repaired.It was found that in Sriwulan Village, the highest compressive strength is 49.37 MPa at age 14 month whilethe highest compressive strength value is on the in PucangGading is 50,51 MPa at age 13 month. It was also found that destructive test using Core Drill Test was conducted at age 14 month after the masonry wall have been repaired. The highest compressive strength in Sriwulan village was 58,6 MPa and in PucangGading was 82,63 MPa.

Abstract

The research was conducted to investigate the performance of old repaired columns inSriwulan Village (Sayung) and Pucang Gading. The performance of 3 columns wasinvestigated by non destructive test and destructive test at age of repaired columns at 12, 13,and 14 months. Non destructive test conducted by Hammer Test while destructive testconducted by Core Drill Test. The results of research has shown that from Hammer Test,highest compressive strength at age 14 months was 45,65 MPa. For Core Drill Test results,the highest compressive strength 73,62 MPa found in Pucang Gading at column 1 at zone A byage 14 months while the lowest at same site and column at zone C 14,22 MPa

Abstract

Penelitian ini menggunakan amylum sebagai polimer termodifikasi dan madu sebagai bahan tambahnya, dengan madu memiliki 3 kompoisi yaitu, 0 %; 0,03 %; dan 0,3%, serta di setiap komposisi madu terdapat 6 kompoisisi amylum yaitu, 0,1 %; 0,2 %; 0,5 %; 1 %; 2 %; dan 5 %. Jumlah benda uji berukuran panjang 20 cm, dan diameter 10 cm adalah 270 benda uji untuk pengujian kuat tekan, dan jumlah benda uji berukuran panjang 30 cm, dan diameter 15 cm total adalah  90 benda uji untuk uji kuat tarik belah. Hasil penelitian menunjukkan bahwa: (1)Pada pengujian kuat tekan beton, hasil optimum yang didapat adalah benda uji KT-M0,03-G dengan komposisi bahan tambah madu sebesar 0,03% dan amylum sebesar 0,5% dari berat semen; (2)Pada pengujian kuat tarik belah beton, didapat hasil optimum pada benda uji KTB-M0-A dengan komposisi madu 0% dan amylum 0,10% dari berat semen.Kata Kunci: beton polimer termodifikasi; kuat tekan; kuat tarik belah;  amylum; maduABSTRACT  The resesearch used amylum as a modified polymer and honey as its added ingredient. There were with 3 compositions with honey, 0%; 0.03%; and 0.3%, and also 6 amylum compositions, 0.1%; 0.2%; 0.5%; 1%; 2%; and 5%. The number of specimens with 20 cm in length and 10 cm were 270 that were tested for compressive strength, and the number of specimens with 30 cm length and 15 cm in diameter were 90 that tested for splittingtensile strength. The results of this research met conslusions: (1). Optimum compressive strength achieved by specimen KT-M0,03-G with 0,03% honey and 0,5% amylum of cement weight; (2) Optimum splitting tensile strength achieved by specimen KTB-M0-A with 0,% honey and 0,10% amylum of cement weight;  Keyword:modified polymer concrete;  compressive strength; splitting tensile strength; amylum; honey

Abstract

Polymer modified concrete has become innovative materials to increase durability and sustainability of concrete. It is now important to develop natural polymers that are ‘greener’ than other chemical polymers. Therefore, this research wants to investigate compressive strength of natural polymer modified concrete added with Moringa oleifera powder, with and without its skin. This research was conducted experimentally in laboratory. There three compositions concrete mixture of several concrete cylinder specimens with dimension 10 cm x 20 cm which were cured in plain water for 7, 14, and 28 days. Compressive strength of normal concrete were designed as about f’c = 30 MPa. All specimens were tested for compressive strength after curing. This research meets conclusions: (1) Natural polymer modified concrete added by Moringa oleifera with skin specimens have compressive strength 82.85% compared control specimens; (2) Extreme high compressive strength has achieved by natural polymer modified concrete added by Moringa oleifera without skin specimens that have compressive strength 165,2% compared control specimens; and (3) Natural polymer made of Moringa oleifera is proven to increase the compressive strength of concrete

Abstract

Kota Makassar menjadi salah satu kota dengan tingkat pembangunan infrastruktur yang tinggi dan menyebabkan perubahan lahan yang sangat signifikan. Fenomena tersebut berdampak pada pola aliran di permukaan (surface flow) dan wilayah resapan air. Tujuan penelitian tugas akhir ini adalah untuk mengetahui karakteristik hidrologi DAS Tempe Sungai Bila di Kota Makassar.Penelitian ini menggunakan model hidrologi dengan bantuan software Hydrologic Engineering Centers Hydrologic Modeling System (HEC-HMS). Hidrograf yang dihasilkan HEC-HMS berupa outflow diolah untuk mengetahui karakteristik DAS Tempe Sungai Bila.Hasil penelitian menunjukan bahwa parameter yang digunakan pada simulasi tersebut sesuai dengan parameter yang ada. Dari analisis outflow didapatkan karakteristik hidrologi DAS Tempe selama tahun 2003 sampai dengan tahun 2013 antara lain debit maksimum rata-rata sebesar 81,46 mm; debit minimum rata-rata sebesar 1,05 mm; koefisien regime rata-rata sebesar 170,48 mm dan koefisien storage sebesar 0,06 mm.

Abstract

The research aimed to investigate the durability of natural modified polymer mortar with amylum and honey admixture of aggressive environment that was modeled by 3 curing media, sea water, brakish water, and tidal flooding water. There were 855 specimens of mortar cubes with addition of amylum of 0,1%, 0,2%, 1%, 2%, and 5% and also honey of  0%, 0,03%, and 0,03%. All specimenswere cured and distributed into 3 curing medias for 7, 14, and 28 days. The result of this research met conclusion that optimum compressive strength was achieved by specimen with composition 0,1%  amylum and  0,03% honey that was cured by sea water.
