Abstract

A reinforced concrete structure can guarantee its safety by giving strengthcapacity or design strength more than any combination of working load effect. Designstrength can be obtained by multiplying normal strength with reduction value of fstrength less than one and nominal load is multiplied with the load factor with the valuemore than one. It can be written as factored resistance ³ effect of factored loads.Resistance factor can be expressed in some ways. Such as ACI Building Code wasexpressed as fRn ³ D Dn + L Ln, where f was resistance factor and D, and L wereload factor for dead load and live load. Meanwhile CEB explained about resistancefactors with reduction factor directly to its material, fc`/c and fy/s where c and s were partial material of safety factor or under strength material factors for concrete and steel.Herewith result from concrete material variability, the variety coefficient compressionstrength of concrete ( Wfc) had great influence to the reduction factor both globalreduction factor from ACI and material partial reduction factor from CEB. The increaseof load ratio (L/D) would add space between factor of dead load (D) and live load (L)were wider. With the increase of the value index gave the increase of safety condition.The result of the study was obtained that the influence of small dimension was to theglobal reduction factor and material partial reduction factor. After comparing the resultsobtained from the calculation method using global reduction factor (ACI) with materialpartial reduction factor (CEB), it could be drawn a conclusion that for beam and coloumusing global reduction factor, its capacity to hold dead load was more than 13 % thanmaterial partial reduction factor.

Abstract

Pengembangan pariwisata di Indonesia memiliki potensi besar sebagai sumber pendapatan negara, terutama untuk daerah-daerah yang memiliki kekayaan alam dan budaya ‘tumpah ruah’. Pulau Bali adalah tujuan pariwisata paling eksotis di Indonesia karena memiliki sesuatu yang istimewa. Salah satu isu lingkungan di Bali adalah pencemaran air bersih yang disebabkan oleh meningkatnya pembangunan akomodasi pariwisata seperti salah satunya, yaitu hotel. Kerusakan pada lingkungan bisa terjadi apabila pembanguan yang dilakukan tidak memperhatikan aspek-aspek di sekitarnya seperti penggunaaan lahan yang efektif, hemat dalam penggunaan energi dan air serta pemilihanan material yang ramah lingkungan. Green Building dapat menjadi salah satu solusi di bidang konstruksi. GBCI membuat suatu perangkat penilaian yaitu Greenship Exisiting Building yang dibuat khusus untuk gedung yang sudah terbangun mengingat bahwa gedung existing yang menerapkan konsep Green Building di Indonesia masih sangat kurang. Sertifikasi Green Building pada gedung existing dapat dilakukan dengan cara menerapkan beberapa perubahan pada gedung tersebut agar menjadi lebih ramah lingkungan. Penelitian ini dilakukan untuk mengetahui persentase Green Building dengan perangkat penilaian Greenship Existing Building Versi 1.1 dan memberikan rekomendasi teknis sehingga Umalas Hotel & Residence dapat melakukan beberapa perubahan yang mengarah kepada penerapan konsep Green Building. Dari 40 kriteria kredit dengan poin maksimal 117, gedung Umalas Hotel & Residence memperoleh 54 poin. Persentase memenuhi kriteria Green Building sebesar 46% sehingga dapat dikategorikan dalam predikat Silver.

Abstract

Badung Selatan yang meliputi Kuta dan Kuta Selatan merupakan industri pariwisata yang jumlah penduduknya banyak. Namun meningkatnya jumlah penduduk dan industri pariwisata tak didukung dengan pasokan air yang ada. PDAM Badung terus berupaya meningkatkan pasokan air baku dengan melakukan normalisasi yang salah satunya akan direncanakan dengan menggunakan air limbah yang telah diolah sebagai sumber air baku. Tujuan penelitian ini adalah untuk menganalisis teknis dan finansial pemanfaatan air limbah sebagai alternatif air baku air bersih. Metode yang digunakan dalam aspek teknis adalah metode simulasi dan analisis dengan program komputer serta eksperimen dengan pengujian di laboratorium, dan pada aspek finansial menggunakan metode kuantitatif yaitu perhitungan biaya-biaya, nilai manfaat dan metode evaluasi investasi selama 15 tahun. Hasil penelitian untuk aspek teknis menujukkan air IPAL diasumsikan layak dan tetap dibuatkan kajian analisis perencanaan teknis untuk sistem jaringan pipa. Hasil evaluasi investasi menunjukkan layak secara finansial dari alternatif jalur rawa-rawa maupun jalan raya. Pemilihan jalur alternatif yang lebih direkomendasikan adalah melalui alternatif jalur jalan raya Tanah Kilap karena biaya yang diinvestasikan, pelaksanaan dan pemeliharaannya relatif lebih terjangkau dengan nilai investasi yang tidak jauh berbeda dengan jalur rawa-rawa yaitu dengan nilai NPV : Rp 9.957.810.192, BCR : 1,2, IRR : 15,91%, PP : 12 Tahun, dan BEP pada tahun ke 7.

Abstract

Keberhasilan sektor pertanian tidak terlepas dari manajemen pengelolaan sistem jaringan irigasi dan peran serta pemangku kepentingan yaitu pemerintah dan pengelola subak. Sampai saat ini masih banyak permasalahan yang dialami dalam pengelolaan jaringan irigasi akibat kurang optimalnya peran serta pemangku kepentingan, lambatnya respon penanganan terhadap masalah pengelolaan jaringan irigasi sehingga berdampak pada tidak meratanya pembagian air dari saluran tersier ke areal pertanian. Hal ini juga terjadi pada Daerah Irigasi (DI) Tiyingtali yang mengalami permasalahan jaringan irigasi seperti terjadinya sedimentasi pada saluran sekunder yang mengakibatkan besarnya volume pelimpahan air saat musim hujan, serta kurang optimalnya pembagian air dari hulu ke hilir. Sehingga penelitian ini bertujuan untuk menganalisis peran serta pemangku kepentingan dalam pengelolaan jaringan irigasi pada DI Tiyingtali. Pendekatan yang digunakan dalam penelitan adalah dengan pendekatan eksploratif dan metode deskritif analitis. Pengumpulan data dilakukan menggunakan kuisioner dan wawancara. Teknik pengambilan sampel/responden pada penelitian ini menggunakan metode purposive sampling, yaitu responden yang menangani pengelolaan jaringan irigasi di DI Tiyingtali yang mecakup pemerintah 25 responden dan pengelola subak 33 responden. Analisis data dilakukan menggunakan regresi linear untuk menganalisis pengaruh peran serta pemangku kepentingan terhadap pengelolaan jaringan irigasi. Selanjutnya dilakukan analisis deskriptif dari hasil wawancara untuk merumuskan upaya peningkatan kinerja dan peran serta pemangku kepentingan. Hasil penelitian menunjukkan pemangku kepentingan berperan sebesar 68,3% dalam pengelolaan jaringan irigasi, sedangkan 31,7% sisanya dipengaruhi oleh faktor lainnya. Pemangku kepentingan secara bersama-sama berpengaruh signifikan secara simultan dan secara parsial terhadap pengelolaan jaringan irigasi artinya peningkatan peran serta pemangku kepentingan secara simultan maupun parsial akan meningkatkan kegiatan pengelolaan jaringan irigasi.
