Mopah airport has one runway that is supported by an apron which is located at a distance of 472 m from touch down to the size of 18.560 m2. Apron between the runway with two lines connected to the taxiway. One of the airside facilities Mopah Merauke airport is the runway strip that serves as a countermeasure state of emergency when the air out of the runway failure when landing or taking off. the objective of this study is to redesign the runway strip by evaluating geometric, cut and fill and CBR in Merauke Mopah Airportusing KP. 39 in 2015, KP. 93 The year 2015 and KP. 576 in 2011. The data taken is the carrying capacity of the soil and ground elevation using test equipment Theodolite and Dynamic Cone Parameter. Results of testing the design of the runway strip Merauke Mopah Airport with dimensions of the runway with a length of 2500 m and a width of 45 m with the code type “4.C”, obtained the runway strip width of 150 m plan right side and the left side of 150 m. CBR value of research in getting 9.93% which comply with minimum CBR value that is 6%, and a transverse slope of the runway strip elevation plan by 0.8%, to meet the slope of the runway strip elevation plan of each cross-section the importance of the volume of cut and fill with amounting to 174,205.00 m3 to 3008.80 m3 excavation and embankments.

Increasing population, residential and land development of the narrow lead to flooding or waterlogging during the rainy season. Based on the author’s observation that this occurs as a result of population growth and settlement. Areas that were once as a rain water reservoir and the water reservoir tidal inland transformed into residential areas and development centers of economic activity, and social services. The residential area of Merauke teacher education road is low-lying areas and densely populated, thus increasing the flow of water entering the waste stream. Based on the calculation of discharge, obtained Qk = 79,586,978.48 m3 / sec. The magnitude of the flood Q Qb = 24,488,511, 58 m3 / sec obtained high discharge may cause flooding in the residential area of teacher education path Merauke. So it is necessary to increase the dimensions of the existing channels in order to cope with flooding during the rainy season.

The number of buildings or constructions which are at the planning or implementation stage can not be allowed to avoid land base in the form of clay, then, of course, it takes geotechnical engineering to solve the problem by improving the native land so hopefully not happen settlement or deformation. Awareness of the importance of the soil remediation process before building construction on it be an idea to use bamboo as a material provision of soil reinforcement. This research was conducted with the full-scale reinforcement and the raft bamboo poles on the ground with a mounting base plate and observations settlement every day. From the results of modeling on the field at the U-50% condition waiting period ranges from 10-14 days, on the condition of the U-90% the waiting time ranges from 40-55 days, on the condition of the U-95% the waiting time ranges from 53-72 days and the condition of the U-99% the waiting time ranges from 83-115 days. Based on observations in the field, the final drop-readable embankment around 545 mm with a time of consolidation U-90% for 59 days. The results showed that retrofitting with bamboo raft poles can reduce the decline to 60.70%.

Ada informasi ketinggian permukaan tanah lingkungan perkotaan Merauke sekitar 0-4m dpl dari kantor statistik, tetapi tidak menyajikan bentuk garis konturnya sehingga estimasi genangan dan aliran air sulit diprediksi. Peta topografi tidak selalu tersedia dan tidak ada jaminan memperoleh dengan cepat dan sesuai, sehingga menuntut upaya pemanfaatan perangkat lunak yang dapat menghasilkan garis kontur sesuai lokasi yang direncanakan. Pada eksperimen pembuatan kontur ini yang disiapkan adalah Google Earth, TCX Converter dan Surfer. Hasil diperoleh informasi ketinggian kontur 1–10 m dpl untuk keseluruhan zona path. Pesisir ketinggian 1 m dpl. Lingkungan perkotan rata-rata 4–8 m dpl. Dan 4 spot kecil ketinggian 9–10 m dpl. Kontur ini tidak sesuai berdasarkan data BPS dan fakta lapangan ketinggian dataran perkotaan Merauke hanya 1–4 m dpl. Faktor ketinggian badan bangunan sekitar 4 m, ketinggian atap sekitar 6 m, dan bangunan lantai 2 sekitar 8-10 m. dengan demikian citra satelit menterjemahkan ketinggian bangunan sebagai ketinggian permukaan tanah yang ditranslate ke dalam garis-garis kontur. Pembuatan kontur topografi melalui citra satelit dalam lingkungan perkotaan Merauke tidak dapat digunakan sebagai dasar rancangan pembangunan fisik, tetapi dapat dipakai sebagai salah satu alat pengukuran zona kenaikan badan bangunan pada ligkungan permukiman atau perkotaan.
