Abstract

As a consequence of the rapid development of infrastructures, there is a scarcity of availability of skilled labor in construction services, so efforts are needed to accelerate the preparation of experts in the field of construction services. Intensive apprenticeship pattern is a program to accelerate the preparation of construction service workers in increasing the relevance of higher education to the world of work as a purpose in this study. Data analysis used comparative analysis and descriptive statistics. The results of the study show that the existing pattern of internship in the field carried out by the sample universities is that there are two things that have not been widely implemented, namely the provision of insurance and special facilities. While other items related to the implementation of internships have a percentage of more than 50 percent. The apprenticeship patterns that can be implemented include through the process of collaboration, socialization, participant registration, self assessment, matriculation, implementation of internships, appraisal, and granting certificates from the Construction Services Business Entity (CSBE/ BUJK). Whereas Certification is carried out in general through Pre-Internship, Internships, Judicium, Post-Judiciary, Graduation and Certification of Young Experts.

Abstract

Changing environment and increasing community demands encourage Public Sector Organizations to begin to focus on the community and its services. However, the majority of Public Sector Organizations are considered slow in improving their services. This service sector is considered far behind compared to services in the private sector. Therefore, the fastest way to be able to match or even goes beyond is to implement systems and governance of private sector organizations to the public sector. One of the “tools” for the private sector that has been successfully applied in improving the performance of the public sector in different countries is “Total Quality Management”. Total Quality Management (TQM) is the philosophy that requires behavior change at every level of the organization to achieve competitive advantage by being customer-oriented. This study aims to examine the application of TQM on service quality at the information and complaint service office of the Directorate General of Taxation. The type of research that used in this paper is qualitative data. The result of the study found that quality is the main factor in service organization services. Total Quality Management has been implemented effectively at the information and complaint service office of the Directorate General of Taxation.

Abstract

Greywater is categorized as domestic wastewater with a light pollutant concentration. The discharge of untreated greywater into the environment will decrease the environment quality, especially water bodies. This study aimed to investigate the performance of the combined vertical and horizontal sub-surface constructed wetlands in removing pollutants and recycling the greywater for a clean water alternative. The greywater sample was taken from the discharge point of the Rectorat Building of the Universitas Negeri Malang. The water bamboo plant (Equisetum hymale) was used in the experiment. The vertical sub-surface constructed wetlands dimensions were 50 cm in length, 50 cm in width, and 80 cm in height. While the horizontal one has dimensions 50 cm of length, 30 cm of width, and 30 cm of height. The water flowrate was designed to be 30 ml/min with a residence time of 3 days. The results showed that the hybrid constructed wetlands could reduce the pollutant concentration to meet the discharge consent. The efficiency of removal was TSS by 88% and BOD by 85%.

Abstract

Pada tahun 2018 Desa Loki mengalami banjir yang merendam pemukiman warga setinggi 0.5 – 1 m. Banjir terjadi akibat kapasitas alir dari Sungai Way Laala yang tidak mampu menahan debit banjir limpasan akibat endapan sedimen yang terjadi karena degradasi lahan pada daerah aliran sungai Laala. Penelitian ini bertujuan untuk memberikan acuan dasar pemilihan solusi pengendalian banjir dengan melakukan perbandingan permodelan aliran banjir unsteady flow dan steady flow. Metode analisis data hidrologi menggunakan software HEC-HMS serta hidraulika dengan software HEC-RAS 5.0.7. Perhitungan curah hujan rata-rata wilayah diambil dari data hujan BMKG, Kairatu dan diperoleh hasil 144,69 mm. Sedangkan untuk perhitungan hujan rencana digunakan metode distribusi Log Person Tipe III dan didapatkan curah hujan rencana 25 tahun sebesar 290,46 mm. Data hujan kemudian dilakukan uji keabsahan data dengan uji Smirnov-Kolmogorov dan Uji Chi Kuadrat. Analisis hidrologi menggunakan program bantu HEC-HMS dan Microsoft excel 2019 dengan membandingkan 3 metode hidrograf satuan sintetik. Hidrograf dibandingkan antara metode SCS, Snyder, dan Nakayasu dengan data kondisi dilapangan saat permodelan banjir untuk kalibrasi data. Hasil permodelan HEC-HMS didapat nilai debit puncak metode SCS sebesar 42,9 m3/s, dan metode Snyder sebesar 60,8 m3/s, sedangkan hasil perhitungan dengan ms. Excel 2019 metode Nakayasu didapat nilai debit puncak sebesar 158 m3/s. Analisa hidraulika menggunakan program bantu HEC-RAS 5.0.7 membutuhkan data berupa cross section, long section, data terrain, serta data hidrograf kala ulang 25 tahun hasil permodelan HEC-HMS metode Nakayasu. Analisis HEC-RAS dibandingkan antara model aliran steady flow dan model unsteady flow. Dari HEC-RAS didapatkan hasil bahwa kondisi Sungai Way Laala terjadi overtopping setinggi 0.5 – 1 m pada aliran steady flow dan menggenang permukiman warga di Desa Loki pada simulasi unsteady flow. Hasil permodelan HEC-RAS menunjukan bahwa profil elevasi muka air rata-rata dari permodelan steady flow lebih tinggi dari elevasi yang dihasilkan permodelan unsteady flow. Elevasi muka air rata-rata permodelan steady flow sebesar + 30.519 m, sedangkan untuk permodelan unsteady flow sebesar + 29.849 m. selain itu kecepatan aliran permodelan steady flow juga cenderung lebih tinggi daripada model unsteady flow. Kecepatan rata-rata model Steay flow diperoleh nilai sebesar 2,791 m/s, sedangkan pada model unsteady diperoleh nilai 2,025 m/s.

Hydrological data analysis method using HEC-HMS software and hydraulics with HEC-RAS 5.0.7 software. The calculation of the regional average rainfall was taken from BMKG, Kairatu rain data and the result was 144.69 mm. Meanwhile, for the calculation of the planned rainfall, the Log Person Type III distribution method was used and the 25-year planned rainfall was 290.46 mm. The validity of the rain data was tested with Smirnov-Kolmogorov and Chi Square. Hydrological analysis used the HEC-HMS and Microsoft excel 2019 programs by comparing 3 synthetic unit hydrograph methods. Hydrographs are compared between the SCS, Snyder, and Nakayasu methods with field condition data during flood modeling for data calibration. The results of the HEC-HMS modeling show that the peak discharge value of the SCS method is 42.9 m3/s, and the Snyder method is 60.8 m3/s, while the calculation results with ms. The Excel 2019 Nakayasu method obtained a peak discharge value of 158 m3/s. Hydraulic analysis using the HEC-RAS 5.0.7 program requires data in the form of cross sections, long sections, terrain data, and 25 year return period hydrograph data from the HEC-HMS Nakayasu modeling method. The HEC-RAS analysis was compared between the steady flow model and the unsteady flow model. From the HEC-RAS, it was found that the Way Laala River was overtopped as high as 0.5 – 1 m in steady flow and inundated residents’ settlements in Loki Village in the unsteady flow simulation. The HEC-RAS modeling results show that the average water level profile of the steady flow model is higher than the elevation produced by the unsteady flow model. The average water level for the steady flow model is + 30,519 m, while for the unsteady flow model it is + 29,849 m. besides that the flow velocity of the steady flow model also tends to be higher than the unsteady flow model. The average speed of the Steay flow model is 2.791 m/s, while the unsteady model is 2.025 m/s.Keywords: flood discharge, flood control, unsteady flow, steady flow, Way Laala River

Abstract

The development of housing infrastructure in Indonesia, including in Tegal Gondo Village, Karangploso, Malang, has attracted people to develop multiple levels house. However, the fluctuating soil conditions (groundwater level fluctuating) became a problem because several houses had cracks in the sloof and walls. Therefore, shallow foundation planning needs to be done by considering the reduction coefficient of soil bearing capacity. This research involved field data collection, laboratory testing, and analysis using Plaxis Version 8.2 software and manual calculations using the Terzaghi formula. The results showed a φR value (reduced soil carrying capacity) of 0.64 at a depth of -1.00 m, and a φR value of 0.55 at a depth of -2.00 m.
