GET’S Hotel Building Semarang has an irregular shape. This building has a letter “L” shape. Separation of building (dilatation) is planned to transform an irregular building becomes a regular building. By construction of the regular building, it is expected the stiffnes and mass distribution tens to be coincide in position or at least be closer. In the condition, when the building shaking because of earthquake, it will cause a small torsion. Structure design of GET’S Hotel Semarang in this final project is designed by Special Moment Frame Bearer System (SRPMK) in Semarang’s seismic zone. By chosing Special Moment Frame Bearer System (SRPMK), it is expected the structure has a high ductility. Ductile structure is a kind of structure types which is able to has a large post elastic deviation repeatedly and frequently because of earthquake that caused the first yield and it is able to maintain the strength of the structure so that the structure remains standing in spite of the edge of collapse. This structure is designed by using a capacity design of Strong Column Weak Beam. In this condition, the column structure is made stronger than beam structure, so that the part of the beam becomes the first plastic joints. The building will not be collapse totally when the strong earthquake occurs. The joints of the beam-column are designed to prevent the first collapse. The structure analysis of this building is based on SNI 03-1726-2012 and supported by SAP2000 v12 software which the results of the analysis are used to determine the fundamental period of the structure and the forces on the structure. Structural fundamental period on SRPMK has to be limited so that the structure is not very flexible.

ABSTRAKNgadirgo adalah salah satu desa di Kecamatan Mijen Kota Semarang yang memiliki karakteristik hidrogeologis berupa Cekungan Air Tanah (CAT) Semarang – Demak daerah imbuhan. Kedalaman muka air tanah pada akuifer tidak tertekan adalah ±30 m dibawah permukaan. Pada daerah CAT air mengalir didalam tanah baik pada tanah dangkal hingga ke lapisan dibawahnya. Tanah dasar pada daerah tersebut adalah non aluvial, yaitu keras dan kedap air karena terbentuk dari desintegrasi formasi batuan. Ketersediaan air sungai yang terdapat pada daerah cekungan air tanah lebih banyak dari pada daerah bukan cekungan air tanah karena air hujan akan meresap kedalam tanah menjadi aliran dasar. Untuk memenuhi kebutuhan air baku dan irigasi maka diperlukan embung, sehingga bisa menampung air pada musim hujan untuk digunakan pada musim kemarau. Ketersediaan air dihitung menggunakan metode F. J Mock yang telah dimodifikasi. Embung diperlukan di sungai Blorong dengan Luas DAS 5,014 km2 untuk mengairi daerah irigasi seluas 109 Ha. Embung ini merupakan urugan tanah yang didesain dengan debit banjir rencana periode ulang 25 tahun menggunakan metode HSS Gama 1 dengan kapasitas sebesar 29,48 m3/detik. Volume tampungan sebesar 5.498.487,961 m3 diharapkan bisa memenuhi kebutuhan air baku dan irigasi. Material timbunan embung menggunakan tanah dari daerah sekitar lokasi. Pembangunan embung ini sangat bermanfaat bagi kelestarian dan keberlangsungan sumber daya air. Embung direncanakan akan dibangun setinggi 15 m dengan lebar puncak 6 m dengan estimasi biaya Rp 8.335.336.463,00 (Delapan Miliar Tiga Ratus Tiga Puluh Lima Juta Tiga Ratus Tiga Puluh Enam Ribu Empat Ratus Enam Puluh Tiga Rupiah).

Kedung Ombo is a multi-purposes reservoir used for flood control, hydropower generation, irrigation services, raw water supply, fisheries and tourism. To meet the water demand (demand), the performance of the reservoir should run well. Over time, sedimentation in reservoir increases. Sedimentation problems may affect the operating performance of the reservoir. If sedimentation increases, the effective volume will be reduced then as a result water demand (demand) can not be fulfilled. Therefore, a further study on operating performance Kedung Ombo Reservoir in relation to sedimentation is needed . The results showed that the simulation the best method SOP for some conditions of sedimentation, in year-on-0, the 15th year, and year-to-27 is not seen a significant difference from the value of the operating performance. So it can be concluded that sedimentation is not very big significant on the operation of the reservoir.

ABSTRAK Semakin meningkatnya sektor ekonomi, maka semakin berkembangnya sektor konstruksi. Sektor konstruksi juga merupakan sumber utama yang bertanggung jawab atas dampak lingkungan yang ditandai dengan meningkatnya suhu di bumi akibat dari pengolahan material, transportasi, penggunaan peralatan pada saat proses konstruksi, proses pembongkaran/ demolisi (Kendall, Keoleian, & Helfand, 2008). Untuk mengetahui dampak lingkungan dari suatu siklus hidup konstruksi diperlukan suatu metode yaitu Life Cycle Assessment (LCA). Ruang lingkup LCA terbagi menjadi empat, yaitu : cradle to grave, cradle to gate, gate to gate, dan cradle to cradle. LCA merupakan metode yang sangat cocok digunakan untuk penilaian lingkungan dari siklus hidup konstruksi sipil (Penadés-Plà, Martí, García-Segura, & Yepes, 2017). Untuk menghitung proses estimasi kebutuhan energi pada tahap transportasi, produksi dan konstruksi secara garis besar dengan cara menghitung besaran konsumsi bahan bakar yang digunakan oleh peralatan dengan satuan liter, sedangkan rumus untuk menghitung besaran kosumsi yang digunakan dengan menghitung konsumsi bahan bakar per jam untuk setiap alat yang ditinjau (Mulyana, 2017).
