The research aims to determine ( 1) the wede168 increase of compressive strength of concrete with addition of fly ash to be compared to normal concrete ( 2) the resistant of normal concrete and also concrete with fly ash mineral additive in 2%, 5% and 7% sulphuric acid solutions, and ( 3) the resitant of concrete with fly ash mineral additive with the increase of concentration of sulphuric acid solution in comparing normal concrete.The method employed in this research was experimental method, by preparing the test object constituting the concrete cylinder with Æ 150 mm and 300 mm height for the compressive strength test. With the percentage of fly ash addition are 0%, 20%, 30% and 40% from requirement cement and qualities of designed concrete is 22,5 MPa. Amount of object test to the each condition is 4. To know concrete resistant in sulphate aggression environment, hence conducted by immersied of concrete in sulphuric acid solutions with concentration 2%, 5% and 7% during 30 days.From the research, it can be found that: ( 1) the addition of fly ash into fresh concrete will improve compressive strength of concrete. At addition fly ash 20% from requirement cement, compressive strength of concrete increase 23,39%. For the addition of fly ash 30% and 40%, the increase of compressive strength concrete were 21,54 % and 0,31%. While in optimum percentage of fly ash addition is 23,46% (2) the immersied concrete in sulphuric acid solution result degradation compressive strength of concrete. At the same concentration of sulphuric acid solution, concrete with fly ash additive mineral have resistant which is better to be compared to normal concrete. This seen [at] percentage of compressive strength degradation of fly ash concrete which is smaller to be compared to normal concrete. Equally the percentage of compressive strength degradation inversely proportional with the percentage of fly ash addition ( 3) the increase of concentration of sulphuric acid solution will be result of aggression that happened at ever greater. If compared to normal concrete, concrete with fly ash in the reality more effective if used at high concentration of sulphuric acid solution. This matter can be seen from difference of percentage of compressive strength degradation ever greater at the height of concentration of sulphuric acid solution.

Abstrak: Masa pandemi Covid-19 telah banyak mempengaruhi sistem perekonomian di berbagai negara termasuk di Indonesia. Salah satu cara yang dilakukan Pemerintah Indonesia untuk mengendalikan perkembangan perekonomian negara ialah dengan melakukan realokasi dan refocusing anggaran. Salah satu dampaknya terhadap penyelenggaraan jasa konstruksi adalah dapat menyebabkan keterlambatan penyelesaian proyek. Untuk mengantisipasi keterlambatan ialah dengan melakukan percepatan dengan memperhatikan faktor waktu, biaya, dan mutu, agar dapat memperoleh biaya optimum, waktu yang efektif, dan mutu yang sesuai standar. Metode penelitian yang dipakai dalam menganalisa keterlambatan dengan menggunakan critical pathmethod (CPM), dimana pekerjaan yang terkena jalur kritis dapat dilakukan percepatan. Dari beberapa item pekerjaan yang dilakukan percepatan, dengan menganalisa beberapa alternatif percepatan dari beberapa item dan menentukan nilai yang paling optimum dari beberapa opsi tersebut.Hasil analisa menunjukkan bahwa kegiatan yang termasuk dalam lintasan kritis ialah A1-A2-A3-A4-B1-B2-D1-D2-D3-E1-E2-F1. Namun yang dilakukan percepatan hanya 2 item pekerjaan yang memungkinkan terjadi keterlambatan yaitu kegiatan D2, dan E1. Lingkup pekerjaan rekonstruksi memiliki durasi normal 389 hari dengan biaya sebesar Rp. 18.577.999.000,-. Setelah dilakukan penjadwalan ulang menggunakan CPM memiliki durasi 226 hari. Alternatif penambahan jam kerja lembur dilakukan 1 kali crashing dengan durasi optimum 224 hari pada pekerjaan laston lapis aus (AC-WC) lebih cepat 0,88% dengan biaya optimum Rp 18.538.850.678,- sedangkan untuk alternatif shift kerja dilakukan 1 kali crashing dengan durasi optimum sebesar 206 hari lebih cepat 8,84% dengan total biaya sebesar Rp 18.371.275.091,-. Dari kedua kondisi tersebut, alternatif percepatan yang dipilih dalam upaya mempersingkat durasi proyek jalan adalah dengan menerapkan shift kerja. Abstract: The Covid-19 pandemic has greatly affected the economic system in various countries, including Indonesia. One of the methods used by the Indonesian government to control the development of the country's economy is by reallocating and refocusing the budget. One of the impacts on the implementation of construction services is that it can cause delays in project completion. Anticipating delays is by accelerating by taking into account the factors of time, cost, and quality, in order to obtain optimum cost, effective time, and standardized quality. The research method used in analyzing delays is by using the critical path method (CPM), where work that is affected by the critical path can be accelerated. Of the several work items that are being accelerated, by analyzing several alternative accelerations from several items and determining the most optimum value of the several options. The results of the analysis show that the activities included in the critical path are A1-A2-A3-A4-B1-B2-D1-D2-D3-E1-E2-F1. However, only 2 work items were accelerated which allowed delays to occur, namely activities D2 and E1. The scope of reconstruction work has a normal duration of 389 days at a cost of Rp. 18,577,999,000,-. After rescheduling using CPM has a duration of 226 days. An alternative to adding overtime hours is done 1 time crashing with an optimum duration of 224 days for wear-resistant durable work (AC-WC) 0.88% faster with an optimum cost of Rp. optimum of 206 days faster 8.84% with a total cost of IDR 18,371,275,091,-. From these two conditions, the chosen acceleration alternative in an effort to shorten the duration of the road project is to implement a work shift.

Hasil penelitian ini menunjukkan bahwa menurut persepsi siswa tentang peran PMK dalam pengembangan penguasaan TPVK, muncul tiga masalah utama, yaitu menetapkan tujuan program magang, menetapkan RPP, dan mengenali lingkungan kelas selama proses magang. Mahasiswa calon guru PTB menerapkan kerangka TPVK dalam semua kegiatan pembelajaran selama PMK. Bimbingan guru pembimbing sangat mempengaruhi kegiatan magang mahasiswa.Abstract: The purpose of this study was to find out the perspectives of student teachers in Building Engineering education (BEE) on the role of the educational apprenticeship program (EAP) in the development of Technological Pedagogical Vocational Knowledge (TPVK) mastery. The research method used a mixed method with a sequential exploratory design. Qualitative data comes from photo documentation and video recordings of the EAP activities and the results of interviews. Participants came from students participating in the EAP from the BEE study program at one of the state universitiy in Indonesia. Quantitative data was in the form of an assessment of the Lesson Plan documents selected by cluster proportional random sampling, as clusters were six schools in apprentice locations. Data collection was carried out using semi-structural interview techniques, observations, and documents. Documentation and observation data were validated by extending the observations. Validation of document data based on expert validation. The interview data was validated using a member check. The analysis technique used was theme analysis and quantitative descriptive analysis. The results of this study indicate that according to students' perceptions of the role of the EAP in the development of TPVK mastery, three main issues arise, namely setting the objectives of the apprenticeship program, establishing lesson plans, and recognizing the classroom environment during the apprenticeship process. BEE student teachers apply the TPVK framework in all learning activities during the EAP. The guidance of the supervising teacher greatly influences student internship activities.
