Abstract

Jembatan merupakan bagian dari infrastruktur transpotasi darat dimana berperan penting sebagai penghubung dan mempermudah, memperlancar berlalu lintas. Dengan demikian jembatan dibangun harus kuat dan tahan lama sesuai umur kelas jembatan. Seiring perkembangan zaman lalulintas kendaraan yang semakin padat kendaraan yang bermuatan besar sudah banyak melintas, beban bertambah mengakibatkan penurunan daya dukung jembatan. Jembatan Panosogan lebar jembatan hanya 3 m sudah tidak cukup untuk dua lajur kendaraan roda empat. Penulis ingin merencanakan dengan bentang jembatan 24 m, lebar jembatan 7 m yang terdiri dari 2 lajur. Tujuan penelitian mengetahui pondasi yang cocok untuk jembatan Panosoogan, mengetahui stabilitas abutment, serta mengetahui volume beton yang dibutuhkan. Kebutuhan data yang diperlukan data primer dan skunder dengan teknik pengambilan data ini penulis melakukan wawancara terhadap pihak Perencanaan Bina Marga DPUPR Kabupaten Serang serta document lainnya. Hasil perencanaan dengan data sondir menghasilkan daya dukung tanah pondasi Qult 265,122 t/m², dengan jenis tanah granuller dan nilai faktor keamanan (F. K) 3 dimensi lebar 4,2 m, tebal 0,7 m, lebar kolom 0,8, panjang pondasi 8 m dan kedalaman pondasi 2,4m jenis pondasi telapak sudah cukup kuat untuk digunakan. Stabilitas abutment terhadap geser sebesar 9,401 > 3 (Aman), Stabilitas terhadap guling sebesar 4,616 > 3 (Aman) dan Stabilitas terhadap eksentrisitas (e) 0,131 < 0,7 (Aman) dengan kontrol tegangan tanah pada dasar abutment sebesar 88,374 t/m2. volume beton mutu k-350 ; fc 30, untuk dua buah abutment membutuhkan volume beton sebanyak 119,472 m3.

Abstract

In running a construction project, good management is needed so that the work is carried out on time. Project success is strongly influenced by cost, quality, and time factors. Two important factors that must be considered are cost and time. Project control can be done by applying the Earned Value Analysis method to both aspects. This study aims to evaluate the implementation of the construction of new classrooms at SMK Negeri 1 Tunjungteja. This evaluation is important to assess the extent to which the project is running according to plan in terms of cost, time, and results achieved. EVA methodology was applied to measure project performance. Data was collected from project reports, work schedules, and budgets that had been prepared where the data used was data for the period from week 1 to week 21. The results showed that in week 1 to 21 the SV value was known to be the highest ratio in the week 13 period. Then the SV value in the 1st period to the 21st period found a negative value. For the SPI value, it has a value <1 in the 1st to 21st period except in week 16. After that, it is known that the ETS and EAS values are 0 in the 21st period with a duration of 21 weeks, which means that the work is not in accordance with what has been planned on the job.
