Abstract

B Bangko River is one of tributaries in Batanghari River Basin that is originated from Solok selatan Regency. Bangko River had a flash flood on February 8th, 2016 that resulted in vast destruction of paddy field, residences, bridges, and flood plain. At several points along the river, some changes in river morphology were observed. These changes triggered some concern on safety of buildings and residencies along the riverbanks. Hence, there was a need of a study on changes of river behavior laterally and vertically for structural as well as non-structural measures to control morphological changes of the river. This study aims to find scour depth in current conditions due to various discharge schemes that might occur in Batang Bangko. Scour depth was analyzed using Lacey Channel Regime theory, Blench equation (1969), Blodgett equation (1986), and Pemberton dan Lara equation (1984). Design rainfall was calculated using data from Padang Aro and Muaro Labuh rainfall station from year 2007-2021. Sediment gradation was analyzed at laboratory of Civil Engineering Departement, Politeknik Negeri Padang. The results of scour depth from formulas were compared with actual scour depth of Bangko River. The analysis revealed that with Q25 of 492 m3/s results in scour depth of 1,402 m (Lacey Formula (Novak, ET AL., 2007); 0,588 m of Blench formula, 1,535 m of Lacey formula (R.J. Garde, 2006); 1,361 m of Lacey formula (Direktorat Jendral Sumber Daya Air, 2013). This study concluded that actual scour of 1.1 m is the nearest to Lacey formula (Novak, ET AL., 2007).

Abstract

Referring to the vision and mission of the development of the Special Region of Yogyakarta, the local government is committed to advancing tourism as one of the leading sectors. One form of attention to cultural tourism is by revitalizing the Cosmological Axis area. The Cosmological Axis is an area in the form of an imaginary straight line between Tugu-Malioboro-Keraton to Panggung Krapyak which has been rearranged to its original shape. In order to support the Cosmological Axis towards world cultural heritage, the local government launched an educational tourism program called Jogja Heritage Track which is a tourist transportation service with a city tour concept. One year after the initial launch in July 2022, it was deemed necessary to evaluate the performance of the Jogja Heritage Track bus in terms of the service received by passengers. Gap Servqual was chosen as the analytical method in this study to assess how big the value of the gap that occurs between the level of service received by passengers and the expected performance. Data collection was carried out by distributing questionnaires to passengers and in-depth interviews with regulators and operators. Based on passenger perceptions, the quality of Jogja Heritage Track bus services is not completely good and still requires improvement. This is illustrated by the gap value of -0.09 and the service quality value of 0.98. Of the five Servqual dimensions (Physical Evidence, Reliability, Responsiveness, Assurance and Empathy), the Empathy dimension is positive, which means that service performance on the Empathy dimension is in line with passenger expectations.

Abstract

The national road through Nagari Sungai Lansek, Sijunjung district (3 km long with an effective width of 7 meters) has a relatively high accident frequency where the total traffic accidents in the 2020-2022 range are always increasing. The aim of this research is to identify the factors that contribute to accidents at the research location. Specifically, the research locations are divided into three areas, namely Jorong Cilacap, Jorong Sikayan, and Jorong Sungai Ampang. The characteristics of the accidents observed are the type of accident, time of the accident, type of vehicle, and location of the accident. The analytical approach used in this research is the AEK (Accident Equivalent Analysis) method and correlation techniques. Based on the time of occurrence, the most diverse accidents were found between 06.00-19.00 with a total of 20 cases. Based on the type of vehicle most frequently involved in accidents, data was obtained on private cars and trucks for 17 cases. The type of accident that occurred most frequently was frontal collision with 11 cases. Based on the geographical context of the incident, a total of 11 incidents were observed in the Sungai Ampang area where driver factors contributed to a total of 17 incidents. The age range of drivers involved in accidents ranges from 16-30 years. Efforts to mitigate traffic accidents in the research area include implementing traffic education initiatives as well as implementing strict sanctions for road users who violate traffic regulations. Providing education regarding correct driving techniques and etiquette in traffic, as well as understanding the importance of traffic signs needs to be carried out in line with the provision of signs and improving road lighting at the study location.

Abstract

The success of each job in a construction project influences the success of the project, where labor productivity factors influence the success of a project. If one project activity has problems, it will greatly affect other project activities because construction project activities are interrelated. Labor management is one of the problems that often causes delays in construction work. The lack of effectiveness of the workforce in carrying out their work makes it very difficult to obtain good productivity values. Smoking, taking breaks and eating during working hours are examples of activities that cause less productive work. Hebel wall installation work is a large volume job and requires a large amount of labor. From the description of the problems found related to labor productivity, this research will carry out an analysis of the productivity of the labor installing hebel installation and the influencing factors of labor productivity installing hebel installation on the construction of the Villa Obao 2 project on Jalan Raya Double Six, Seminyak, Kuta, Badung, Bali. This research uses the Productivity Rating method to determine the value of labor productivity in hebel installation work and distributes questionnaires to analyze factors influencing hebel labor productivity. The results of the analysis of labor productivity observed for 7 days, the average LUR value for workers installing hebel was 67.8% > 50%. Of the 10 factors influencing productivity, only 3 factors have a significant influence on productivity. These factors are the Wage Suitability factor (X3) with an influence value of 4.094, the Motivation factor (X7) with an influence value of 4.133, and the Communication Relations Factor between Employees (X9) with an influence value of 5.498.

Abstract

Berkembangnya suatu daerah sangat mempengaruhi pertumbuhan perekonomian, perkembangan tersebut didukung oleh berbagai sektor salah satunya sektor konstruksi. Sektor konstruksi memiliki dampak negatif terhadap lingkungan yaitu masalah limbah. Oleh sebab itu diperlukan waste management yang tepat dan efektif. Salah satu metode untuk mengetahui tingkat penerapan waste management dalam pelaksanaan proyek konstruksi adalah dengan melakukan penilaian terhadap setiap tindakan penanganan limbah dalam suatu proyek konstruksi, salah satunya dapat dinilai menggunakan metode Waste Management Performance Evaluation Tool (WMPET). Penelitian ini bertujuan untuk mengetahui implementasi waste management yang dominan dan untuk menghitung nilai seberapa efektif implementasi waste management yang telah dilakukan oleh developer. Penelitian ini dilakukan dengan menyebarkan kuesioner dan wawancara terhadap developer yang terdaftar dan memiliki keanggotaan aktif di DPD REI Kalimantan Tengah. Hasil penelitian menunjukkan bahwa indikator implementasi waste management yang paling dominan pada proyek konstruksi perumahan di Kota Palangka Raya adalah mencegah pemesanan material yang berlebihan, menggunakan material sesuai standar yang ditetapkan, dan mengurangi risiko kehilangan material selama proses pengangkutan dan penyimpanan. Nilai hasil perhitungan keefektifan waste management berdasarkan penilaian (WMPET) didapatkan sebesar 543,96 dari nilai 1000. Nilai tersebut berada pada rentang indeks 401 – 600 dan mendapat predikat buruk yang berarti bahwa manajemen limbah konstruksi pada perumahan oleh developer di Kota Palangka Raya tidak efektif untuk mengurangi limbah konstruksi maupun meningkatkan kegiatan daur ulang limbah konstruksi. Selanjutnya saran yang diberikan dari penelitian ini, diharapkan developer mempertimbangkan upaya membuat perencanaan manajemen limbah pada proyek konstruksi perumahan untuk meningkatkan keefektifan waste management karena manajemen limbah konstruksi hanya berdasarkan kebiasan dan kebijakan pekerja dalam menangani limbah, diharapkan pihak pemerintah dapat mempertimbangkan untuk mengadakan sosialisasi/pelatihan tentang manajemen limbah konstruksi kepada developer yang berguna untuk meningkatkan penerapan manajemen limbah pada proyek perumahan.

Abstract

Infrastructure development in Indonesia is the main focus of the government, especially in the construction sector with toll road projects, airports, high-speed rail lines, and smart cities in the new capital city. Concrete is becoming the main material in infrastructure because of its high compressive strength and relatively low cost. Aggregates, especially natural and artificial, play a key role in concrete structures. The growth in demand for natural aggregates has an impact on environmental damage due to mining. Innovations using Rice Husk Ash instead of natural aggregates emerged as an environmentally friendly solution. However, it is necessary to optimize the mix design and handle workability reduction with superplasticizers. The percentage of superplasticizers used is 0%, 0.52%, 0.54%, 0.56%, 0.58% of the total use of cement. In concrete workability tests, such as Flowability, Passingability, and Viscosity, it was found that a 0.54% SCCRHA mixture showed optimal performance. The Flowability test showed a Slump Flow runoff value of 77.5 cm (SF3 category), while the J-Ring test showed a runoff of 75 cm with 2.5 cm blocking (No Blocking). The Viscositytest showed T-500 and V-Funnel times of 1.8 seconds and 2.18 seconds, respectively, with VF1 and VS1 (good filling) classifications. The results showed that this mixture achieved the most effective design with a compressive strength of 25.17 MPa, showing an increase of 13% compared to the plan mixture

Abstract

Changes in river mouth section capacity caused by instability of river mouth stability would influence flow conditions in upstream estuaries, as impacted by unsmooth drainage of river flow. Section river capacity and mouth river stability of Siak River would be evaluated by the output of tidal prism at the estuary. The tidal prism was predicted by Hecras software. Input data for hydrodynamic simulation consisted of river geometric data, river bed condition, and boundary condition (discharge and water level). The maximum daily rainfall data and Siak’s catchment parameter could predict flood discharge. Longshore sediment transport netto data could be calculated using wave depth data, wave velocity data and direction of wave around the mouth river. The results of the tidal prism calculation show that the existing cross-sectional area of the mouth of the Siak River estuary can only drain the volume of water due to discharge and tides in the 2-year return period (Amin = 3,115 m2 < A ada = 3,225 m2), while for discharge with other return periods, the capacity of the cross-section river is not sufficient. The excess discharge will flow upstream as a backwater. Siak River mouth stability is still relatively good and stable, with a stability number (S) of more than 388,0 (requirement: S > 150). The start of the backwater effect at KM+220 (60 km from the mouth of the river) caused a significant change in water level (0.94 m) due to the damming of the flow caused by the influence of tides and the bifurcation node of the river (delta).
