Abstract

Pemerataan penyediaan listrik di Indonesia, tak luput pada daerah Lombok Timur. Besarnya permintaan daya listrik di daerah Lombok Timur, menyebabkan Pembangkit Listrik Tenaga Uap Loan Korea Lombok Timur (PLTU) harus menyediakan daya listrik sesuai permintaan masyarakat daerah Lombok Timur. Hal ini mendorong pembangunan mesin Steam Turbine. Pembangunan ini perlu adanya struktur pendukung yang harus direncanakan adalah pondasi mesin. Pondasi mesin selain sebagai penyalur beban dari struktur atas ke lapisan tanah, juga membatasi gerak amplitudo yang tidak membahayakan saat mesin beroperasi. Pondasi mesin yang akan direncanakan menggunakan pondasi mesin tipe blok. Perencanan pondasi mesin ini akan dikelompokan menjadi dua macam pengelompokan mesin. Pengelompokan pertama menopang dua mesin dan pengelompokan ke dua menopang tiga mesin. Setiap pengelompokan mesin direncanakan menjadi dua yaitu ketebalan pondasi yang sama tetapi kedalaman penanaman yang berbeda (empat perbedaan penanaman), dan ketebalan pondasi yang berbeda tetapi ketinggian pondasi di muka tanah yang sama (empat perbedaan ketebalan pondasi). Dari hasil pengelompokan tersebut mendapatkan nilai besaran rasio redaman. iv Pengaruh kedalaman penanaman menghasilkan kurva kedalaman terhadap Amplitudo Vertikal (Az) berbentuk kurva linier. Untuk ketinggian muka tanah 0,4m selisih amplitudo konstan sebesar 0,2% dan untuk ketinggian muka tanah 0,3m selisih amplitudo dengan interval 0,2% dan 0,3%. Sedangkan studi pengaruh ketebalan pondasi mesin menghasilkan kurva kedalaman terhadap Amplitudo Vertikal (Az) berbentuk kurva linier. Dengan setiap penambahan kedalaman sebesar 0,1m nilai amplitudo berkurang secara konstan sebesar 1%. Selain kedalaman penanaman pondasi, nilai dimensi pondasi B x L juga mempengaruhi nilai amplitudo. Semakin besar nilai dimensi pondasi (B x L) semakin kecil pula nilai amplitudo. Adanya studi ini, maka merencanakan pondasi mesin sebaiknya ketinggian pondasi di atas muka tanah tetap, tetapi kedalaman penanaman yang berbeda. Hal ini dikarenakan pada amplitudo cepat berkurang dibandingkan dengan ketebalan pondasi tetap. ======== The equalization of electricity provision in Indonesia, is including the area of East Lombok. The amount of electric power demand in the area of East Lombok, causing the Loan Korea East Lombok power plant must provides the electrical power as the order of the regional community in East Lombok. Accordingly, it stimulate the establishment of steam turbine engine. Those project need the additional structures that have to be planned, such as the machine’s foundation. Machine's foundation aside as a distributor of the load from the upper structure to the soil, also limits the motion of amplitude that is not harmful while the machine is operating. Machine's foundation that will be planned, using the block type of machine's foundation. The plan of this machine's foundation will be group into two kind of machines group. The first group, sustain two engines, while the second group sustain three engines. Each of machine's group are planned into two: have the same thickness of foundation but different in depths of planting (four differences of planting), and differ in thickness foundation but have the height’s foundation in the same ground surface (four differences of foundation’s thickness). From the results of these grouping, get the amount of damping ratio values. vi The impact of planting in depths, generate a depths curve on vertical amplitude (Az) shaped liniear curve. 0,4 m to ground level height difference constant amplitude of 0,2% and for the ground level height 0,3m difference in amplitude with intervals of 0,2% and 0,3%. At the same time, study of the impact of machine’s foundation thickness produces a depth curve of vertical amplitude (Az) shaped liniear curve. With each additional 0.1M depth at constant amplitude value is reduced by 1%. In addition to foundation’s planting depth, those foundation dimension value B x L also affect the value of the amplitude. The greater the value of the foundation dimensions (B x L), it means smaller the amplitude values. Accordingly to this study, the machine’s foundation plan should altitude on the fixed of the ground face, but different in planting depths. This is because in a fast amplitude is reduced compared to the thickness of the foundation remains.
