Badurame Village Street-Geger is a very important means of transportation. This is to support the economy of rural communities. The street is built by self-management way that has 3m wide and 2500m long. Badurame Village Street-Geger is an area that connects one settlement with the other settlements and one of the main accesses to the main road. Given the importance of transportation, the researcher conducted a research to determine the damage that occurred on the street. This study uses Bina Marga method, this method is used as a reference in the implementation, planning and solutions to the damage. From these results, the cause of the road damage on Badurame Village Street-Geger is the lack of reinforcement on the plate, aiming to minimize the lengthwise cracks because cracks is the most dominant reached 9.33% and reduced quality of concrete due to the lack of supervision. Amount of damage on the Badurame Village Street-Geger is the rift that extends reached 9.33%. Waning concrete is 0.08%, collapsed road is 0,093% and cracks crosways is 0.2%. Solutions to overcome damage on the Badurame Village Street-Geger using method or reference from Bina Marga is patching, resurfacing, filling, local reconstruction and overlay.

The technology of artificial geomembrane reservoir or water tank is the small reservoir in the village land (TKD) which is built to collect the water in the rainy season by using waterproof material as the layer by utilizing the rainwater through the river around which is then used as an alternative source of clean water (water supply) in the dry season. As for the calculation methods used for this research include: analysis of rainfall area using algebra average method (arithematic mean), the calculation of rainfall plan can be done by using disperse measurement, with the statistical parameter of calculation result of Sd= 23.884 Cs= 1.933 Ck= 4.031 Cv= 0.233. The distribution analysis is done using Gumbel 1 method for 10 years plan amounted to 146.601 mm/day. Rainfall intensity analysis is done by using Mononobe method for 10 years rainfall intensity plan amounted to 6.108 mm/hour. For the next 10 years population projection is done using calculation of Arithmetic method of 2.795 populations. The conclusion of this research indicates that the clean water need in the dry season at Tanggung Prigel Village, Glagah District in 2026 is approximately 0.001941 m3/sec. While the plan for reservoir debit of 0.003254 m3/sec so it is considered sufficient to fulfill the clean water need in the Tanggung Prigel Village, Glagah District.

Rencana Anggaran Biaya merupakan alat untuk mengendalikan jumlah biaya penyelesaian pekerjaan secaraberurutan sesuai yang telah direncanakan. Tujuan penelitian ini untuk mengetahui selisih perbandingan harga satuan material, upah dan pekerjaan dan mengetahui mana yang lebih tepat antara penggunaan metode HSPK dan SNIuntuk perhitungan rencana anggaran biaya proyek. Pada perhitungan Rencana Anggaran Biaya (RAB) antara SNI dan HSPK terdapat perbedaan harga satuan. Penulis mencoba menghitung kembali rencana anggaran biaya proyek pembangunan Pasar Tradisional Blimbing Lamongan metode SNI dan HSPK dari Kementrian Pekerjaan Umum Bidang Cipta Karya sebagai dasar perhitungan pada proyek-proyek pembangunan Pasar Tradisional Blimbing Lamongan. Analisa perbandingan biaya pada pekerjaan konstruksi baja pada proyek pembangunan Pasar Tradisional Blimbing Lamongan didapat jumlah Rencana Anggaran Biaya Metode SNI sebesar Rp. 3.833.857.779,56 dan Metode HSPK sebesar Rp. 3.786.269.875,30. Maka selisih jumlah harga dari Metode SNI dan HSPK adalah Rp. 47.587.904,26. Hal ini terjadi karena faktor-faktor yang menyebabkan selisih harga, antara lain: Harga upah/tenaga yang berbeda serta harga bahan bangunan yang berbeda. Untuk koefisien yang dipakai dalam perhitungan menggunakan SNI dari Kementrian Pekerjaan Umum Bidang Cipta Karya.

Concrete from construction waste resulting from the construction of new infrastructure replacing old infrastructure can significantly impact the environment. Therefore, there is a need for the proper management of concrete waste. One of the uses of concrete waste is to use it as a coarse aggregate material in the manufacture of Concrete. Using waste concrete is obtaining a material that almost resembles coarse aggregate. This study aimed to determine the optimum content of Concrete with the addition of waste concrete as a substitute for coarse aggregate. This research refers to the standards of SNI and ASTM. The research was conducted by testing the waste concrete to determine whether it is suitable for coarse aggregate material. After that, the compressive strength was tested by curing for 28 days. This research was conducted with 3 samples with 0%, 50%, and 100% of the planned use of concrete waste with concrete compressive strength of Fc' 20,75 MPa. The results showed that the average compressive strength of the 50% concrete waste was 20.59 MPa, and the 100% concrete waste was 13.83 MPa. From these results, it can be seen that the most optimum content of substituted aggregate is a mixture variation of 50%, so the results of this study can be used as a reference in the utilization of recycled concrete waste as a raw material or a substitute for the composition of the concrete mixture.
