Increasing the level of productivity relates to the time needed to complete the work and will directly affect the amount of costs needed. Particularly from the reduction in costs consumed by construction workers. The costs allocated to these workers contribute to the auction / tender process and during the implementation of the project, therefore information about labor productivity is very important to be examined in detail. One way to get field productivity value is by using method productivity delay model. In this study there are 5 labor that observed. Observation take 3 session .first session held before 12 pm, second session held after 12 pm. And third session take randomly beetwen that 2 session. Based on the research that has been done, the results of the analysis are as follows. Field labor Productivity is 2,64 m2/hour and ideal labor productivity is 3,659 m2/hour. Comparation of field productivity and unit price analysis from PermenPUPR-28-2016 is 23,936 times. Biggest delay factor affect productivity is material factor. 2022-01-24T00:00:00Z http://hdl.handle.net/123456789/56112 Geometri Peledakan Dan Pengaruh Getarannya Terhadap Stabilitas Lereng Bendungan Bener, Kabupaten Purworejo Budiono, Andryani Herna; Fathani, Teuku Faisal; Hardiyatmo, Hary Christady Blast geometry is an important factor in blasting activities so that special studies are needed related to the appropriate blast geometry, especially the preparation of Spillway building area on the construction of the Bener Dam. Approach methods used to analyze slope geometry include Anderson's theory, R. L. Ash., and ICI-Explosive. As for the analysis of slope stability, observations were carried out using vibration meter applications and soil material data obtained from laboratory tests. Based on calculations, changes were made in several aspects, namely, burden 2.3 m, space 2.7 m, height level 5.4 m, sub drilling 0.6 m, powder coloumb 2.84 m, stemming 3.16 m. The proposed geometry resulted in a powder factor of 0.29 kg/m3 with an average fragmentation of 30.5 cm. From the results of observations in the field it is also known that there is a change in vibrational level from IV MMI to III - I MMI with a decreased noise and damage.Exception value that initially amounted to 0.66 m / s2 to 0.01 – 0.44 m / s2. The results of the slope stability analysis due to vibrations from blasting stated all slopes were above the safe number (>2.0), so all slopes were declared safe. The ruins that have occurred because there are remnants of chunks due to uneven fragmentation from previous blasts that are large so as to cause a slide on the slopes. 2022-01-24T00:00:00Z http://hdl.handle.net/123456789/56111 Analisis Stabilitas Timbunan Pada Badan Jalan Dengan Perkuatan Geotekstil Menggunakan Program Plaxis Hayumi, Liana; Abdurrozak, Muhammad Rifqi Padang – Pekanbaru Toll Road is a part of the Trans Sumatra Toll Road Network. In implementations, embankment work is carried out on the road to even out the contours of the land at the construction site. With the accumulation of soil, new embankment slopes will need to be analyzed for stability. In the process, the soil embankment is also reinforced with geotextiles to minimize the occurrence of landslides. This study was analyzed by modeling embankment variations of 4 meters, 6 meters, and 8 meters with geotextile reinforcement using the Plaxis V20 program. For calculations on the original soil conditions were analyzed by the fellenius method. The results of embankment stability analysis in the original soil condition with geotextile reinforcement using the Plaxis V20 program during the construction period obtained the safety factor for the 4-meter embankment without earthquake load of 1.893, the 6-meter embankment load of 1.637, and the 8-meter embankment load of 1.622. While in post-construction, the safety factor for the 4-meter embankment without earthquake loads of 1.651, the 6-meter embankment load of 1.572, and the 8-meter embankment load of 1.512. For the analysis settlement of the original soil condition with geotextile reinforcement for the calculation of excess pore water pressure on a 4-meter embankment, the settlement has a value of 0.207 meters with a time of 88 days, a 6-meter embankment has a value of 0.434 meters with a time of 104 days, and an 8-meter embankment has a value of 0.639 meters with a time of 131 days. 2022-01-24T00:00:00Z http://hdl.handle.net/123456789/56110 Pemetaan Risiko Bencana Sebagai Dasar Untuk Mitigasi Bencana Tanah Longsor Di Desa Srimulyo Kabupaten Bantul Winarno, Setya; Aminatun, Sri; Saputra, Elvis Srimulyo Village Piyungan District Bantul Regency is one of the villages that are vulnerable to landslides located on the morphology of the ridge to the hills in the eastern region of Bantul Regency. In each rainy season some areas in the village of Srimulyo landslides occurred. Based on the map of landslide incident from the Regional Disaster Management Agency in 2018, Srimulyo village is one of the villages in Bantul Regency that experienced high intensity of landslide events, one of the ways to mitigate the landslide disaster is to assess and analyze the risk of landslide disaster in detail. This study aims to identify the homes of residents who are in landslide threat zone, be it a high threat zone or medium threat zone. The method used in this research is descriptive method with qualitative approach combined with quantitative method used to give a clear picture about the number of houses in each zonation. Sources of data used are primary and secondary data sources through interviews and documentation. The results of this study indicate that 1) the number of households in the high risk zone is 351 houses, in the yellow risk zone is 369 houses. 2) The village of Srimulyo has a high threat, medium to high vulnerability, and medium capacity, which means having a medium to high risk. 3) Recommended disaster mitigations. 2022-01-24T00:00:00Z
