Residential development in Palembang city is not a simple problem, because residential development need always grows and population growth increases every year, but the supply of land for residential development is limited. The research shows that residential developers have noticed the three factors of land provision for residential development. Based on the physical aspect, the wide area of residential is 4 hectare, and land designation status is garden soil. The easy access and appropriateness to the RTRW are the considerations of developers for building the residence. Based on the institutional aspect, the status of land rights is property rights by way of purchase. Moreover, land supply through land bank is assessed helping the residential developer. Local governments sometimes help the developers, but the developers have difficulty in particular section permits the acquisition of development principles at a location due to government bureaucracy and complex rule. Based on the economic aspect, land prices are cheap and profitable and they become the reasons for choosing the location of residential developers. The price of land per meter2 at the time of purchase was relatively high, indicating the residential developers in Palembang city are very effective in raising the economic of land value. Of the three aspects, the economy aspect is prioritized by residential developers, because residential developers as enterpreneurs have an orientation to get the profit.Keywords: Development, Residential Developer

ABSTRACTAs one country that has 83 volcanoes that are still active, Indonesia has natural resources in the form of volcanic ash which is pozzolan. In addition Indonesia is also a vast country so to support the equitable distribution of supporting facilities such as roads to support the development process. In the implementation of road construction is often found soil conditions that have low bearing capacity. Therefore, it is necessary to handle the subgrade of road that has low carrying capacity through stabilization with agent material.One material that meets the pozzolan material is volcanic ash. Volcanic ash of Mount Merapi has pozzolanik nature that is the nature of materials that will wake solid mass that increases harder as time increases and is difficult to dissolve in water when reacted with CaO contained in clay and lime.The study was conducted with a mixture of volcanic soil with 14 days of curing. Through triaxial testing of the efective confining pressure (σ0) of 547 kN / m2 with void ratio (e) of 1,059. The calculation of shear modulus (Gmax) was done by empirical formula proposed by Zen et al (1978) and obtained Gmax value of 134,044 Mpa as the biggest shear modulus with 25% volcanic ash and 5% lime.Keywords : pozzolan, stabilization, effective confining pressure, void ratioABSTRAKSebagai salah satu negara yang memiliki banyak gunung api yang masih aktif, Indonesia memiliki sumber daya alam berupa abu vulkanik yang melimpah dan bersifat pozzolan. Selain itu indonesia juga merupakan negara yang luas sehingga untuk menunjang pemerataan pembangunan diperlukan sarana penunjang berupa jalan untuk mendukung proses pembangunan. Dalam pelaksanaan pembangunan jalan sering dijumpai kondisi tanah yang memiliki daya dukung rendah. Oleh karena itu perlu penanganan terhadap tanah lunak yang memiliki daya dukung rendah melalui stabilisasi dengan bahan tambah. Salah satu material yang memenuhi material pozzolan adalah abu vulkanik. Abu vulkanik Gunung Merapi mempunyai sifat pozzolanik yaitu sifat bahan yang akan membentuk massa padat yang bertambah keras seiring bertambahnya waktu dan sukar larut dalam air apabila bereaksi dengan CaO yang terdapat pada lempung dan kapur. Penelitian dilakukan dengan campuran tanah-abu vulkanik dengan pemeraman 14 hari. Variasi kadar campuran yang diberikan adalah 0%, 20%, 25%, dan 30%. Selain itu dilakukan penambahan kapur 5% yang bertujuan memberikan ikatan yang baik apabila dicampur dengan tanah lempung.Melalui pengujian triaksial UU diperoleh tahanan kekang efektif (σ0)sebesar360kN/m2 dengan angka pori (e) sebesar 1,059. Perhitungan modulus geser (Gmax) dilakukan dengan rumus empiris yang diusulkan Zen dkk (1978) dan diperoleh nilai Gmax sebesar 134,044 Mpa sebagai modulus geser terbesar dengan kadar abu vulkanik 25% dan kapur 5%.Kata kunci : pozzolan, stabilisasi , tahanan kekang efektif, angka pori

Abstract Musi Rawas Regency is the largest fish producer in South Sumatra Province. Based on the Musi Rawas regency RTRW, there are 3 sub-districts that can be developed into integrated fisheries areas, namely Muara Beliti, Tugumulyo, and Purwodadi. According to a mapping survey, SWOT analysis and technical analysis of the three sub-district locations were held found that Muara Beliti the location was still quiet from the population and far from the fishery center. But technically, the location that has been prepared, and it is very suitable with the RTRW of Musi Rawas Regency. There are already general facilities, has a hard soil structure, and the area of land that can be used is around 5.7 Hectare. The location of Purwodadi is in the middle of the city and on the edge of a big road. However, at this location there is a public market, and most of the land plans that will be used for the development of the community-owned land. The land area is around 1.9 Ha, so it is feared that it will create new problems if it is to be developed in the future.Tthe location in Tugumulyo area is located on inter-provincial road which is located in the middle of the sub-district, near the community housing, the planned land area is around 3.2 Ha, and there are drainage network on the edge and around the area. So, The most suitable for the development of the minnbisnis area in Musi Rawas Regency is in Tugumulyo.Keywords : Minapolitan Area, Mapping Survey, SWOT Analysis Abstrak Kabupaten Musi Rawas adalah penghasil ikan terbesar di Provinsi Sumatera Selatan. Oleh karena itu kawasan minapolitan sangat bagus untuk dikembangkan di kabupaten ini. Berdasarkan RTRW Kabupaten Musi Rawas, ada 3 kecamatan yang bisa dikembangkan menjadi kawasan perikanan terpadu, yaitu Muara Beliti, Tugumulyo, dan Purwodadi. Menurut survei pemetaan, analisis SWOT dan analisis teknis dari tiga lokasi kecamatan yang telah dilaksanakan didapatkan bahwa kecamatan Muara Beliti lokasinya masih sepi dari penduduk dan jauh dari pusat perikanan. Namun secara teknis, lokasi di Kecamatan ini memang disiapkan untuk pengembangan, dan sangat sesuai dengan RTRW Kabupaten Musi Rawas. Sudah ada fasilitas umum, memiliki struktur tanah yang keras, dan luas lahan yang bisa digunakan adalah sekitar 5,7 Hektar. Untuk kecamatan Purwodadi, lokasinya di tengah kota dan di pinggir jalan besar. Namun, di lokasi ini ada pasar umum, dan sebagian besar rencana lahan yang akan digunakan untuk pengembangan lahan milik masyarakat. Luas lahan sekitar 1,9 Ha, sehingga dikhawatirkan akan menciptakan masalah baru jika ingin dikembangkan di masa depan. Sedangkan di Kecamatan Tugumulyo, lokasi untuk pengembangan daerah minabisnis terletak di sisi jalan besar (jalan antar provinsi) yang terletak di tengah kecamatan, tanahnya terletak di lokasi yang berlawanan dengan masyarakat. perumahan, luas lahan yang direncanakan adalah sekitar 3,2 Ha, dan ada jaringan drainase di tepi dan di sekitar area. Dapat disimpulkan bahwa lokasi yang paling cocok untuk pengembangan kawasan minabisnis di Kabupaten Musi Rawas berada di lokasi di Kecamatan Tugumulyo.Kata kunci : Area Minapolitan, Survey Pemetaan, Analisa SWOT
