[ID] Daerah Rawa Pinang Dalam merupakan bagian dari daerah rawa di kawasan Pinang Komplek yang berada di Kabupaten Kubu Raya Provinsi Kalimantan Barat. Tinggi muka air tanah Daerah Rawa Pinang Dalam dipengaruhi oleh pasang surut air laut. Daerah Pinang Dalam diusahakan oleh penduduk sebagai lahan pertanian. Namun hasil produksi pada daerah ini belum optimal yang disebabkan oleh belum baiknya jaringan tata air, dimana sebagian besar daerah tersebut merupakan daerah genangan, sering mengalami banjir pada musim penghujan serta mengalami kekeringan pada musim kemarau. Penelitian ini bertujuan untuk mengetahui jenis dan pengaruh hidrotopografi lahan terhadap saluran tersier, sehingga dapat diperoleh dimensi saluran tersier sesuai dengan peruntukan lahan di daerah rawa Pinang Dalam. Data primer pada penelitian ini yaitu data hidrometri dan data pasang surut, sementara data sekunder yang digunakan yaitu data hidrologi dan data topografi serta peta-peta yang diperlukan dalam analisis hidrotopografi. Data tersebut merupakan dasar dalam melakukan kajian dan analisis hidrometri dan topografi yang diperlukan untuk mengetahui hidrotopografi lahan dengan memperhatikan peruntukan lahan. Hasil penelitian menunjukkan bahwa jenis hidrotopografi lahan di daerah rawa Pinang Dalam terdiri dari jenis hidrotopografi B, C dan D. Berdasarkan jenis hidotopografi dan peruntukan lahan, terdapat kriteria tertentu mengenai kedalaman optimum untuk saluran tersier dalam sebuah jaringan tata air. Saluran tersier yang diperuntukkan sebagai lahan perkebunan sebaiknya diupayakan untuk memiliki kedalaman yang dapat mempertahankan muka air tanah dalam kisaran 60 hingga 90 centimeter, sementara elevasi muka air untuk tanaman padi sawah dipertahankan setinggi mungkin dengan kedalaman perakaran minus (-)10 sampai dengan -30 centimeter. [EN] The Pinang Dalam swamp area is a part of Pinang Komplek swamp area which is located in Kubu Raya Regency, West Kalimantan Province. Groundwater table in Pinang Dalam swamp area is affected by tides. Pinang Dalam area is cultivated by the population as agricultural land. But the production results in this area are not optimal due to the lack of a good water system, where most of the area is inundated, often experiences floods during the rainy season and experiences drought in the dry season. This research aims to identify the type and effects of land hydrotopography on the tertiary channel, thus the dimension of tertiary channel that is suitable for the allocated land use is obtained. The primary data in this study are hydrometric and tidal data, while secondary data used are hydrological and topographic data and maps needed in hydrotopographic analysis. These data are the basis for conducting studies and analysis of hydrometry and topography needed to the hydrotopography of land while taking the land use into account. The results showed that the hydrotopographic type of land in the Pinang Dalam swamp area consisted of hydrotopographic types B, C and D. Based on the hydotopography type and land use, there are certain criteria regarding the optimum depth for tertiary channels in a water system. Tertiary canals on land allocated as plantation area should be striven to have a depth that can maintain water table in the range of 60 to 90 centimeters, while the water level elevation for lowland rice plants should be maintained as high as possible with a rooting depth of minus (-) 10 to -30 centimeters.

This study aimed to develop land use scenarios in District Mapanget using Agroecology Zone-based Geographic Information System (GIS). The data used in this study are primary data and secondary data. Primary data were collected through surveys and direct observations in the field. The activities carried out field surveys to obtain state information field through taking pictures with a digital camera. Analysis of social data and data on potential farming is also done through the compilation of data to map the District Mapanget. Furthermore biophysical data agro-ecological, social and agricultural potential of the data compiled in a database system was using Quantum GIS program version 1.8. This study found that the use of agricultural land to non-agricultural land in the district Mapanget very difficult to avoid due to the low value of land from the agricultural sector compared to other sectors. So based on the evaluation conducted by comparing the map with a map of the existing condition of the District RTRW 2014-2034 Mapanget then it changes the function of which is no longer appropriate region where the agricultural area have been converted into non-agricultural. In order for this condition continues to be bad for the environment and agriculture will require efforts in the management and development in the District Mapanget, among others, the development of urban agriculture, every development in Sub Mapanget should always refer to the scenario Land use and Spatial plan of the District Mapanget that there are both carried out by the government, private or public. Urban agriculture has an important role for urban communities that suggested the need for land use scenarios in District Mapanget. Based on agroecological zone map and a map of the District RTRW 2014-2034 Mapanget then be collated Mapanget the District land use scenarios are divided by 3 (three) scenarios that city Scenario, Scenario frame the city, urban-rural scenario. The existence of land / space urban agriculture plays an important role in agricultural production systems and maintain the quality of the environment, because it is a major determinant spacious RTH (green open space) and the results of urban agriculture.

Many developing countries do not focus on land use planning in hydropower development. As a result hydropower projects are not sustainable. The aim of the study is to analyze the cause and effects of land use planning in hydropower development. The primary and secondary data were collected in a case study site at the Upper Tamakoshi Hydroelectric Project (UTHEP) in Dolakha district of Nepal. Household questionnaire, key informants? interviews and field observation were conducted to collect primary data while the relevant documents such as detailed feasibility report, property valuation report and spatial data (cadastral data, image etc.) were also collected for the study. The primary and secondary data reveals that Land use changes involved in the UTHEP implementation is basically due to the permanent and temporary land acquisition for project structures, facilities and reservoir area. The total land acquired for various project components like access road, powerhouse, desanding basin, reservoir as well as construction borrow pits and quarries, temporary and permanent work camps and construction of access road is estimated to be 182 ha. The secondary data reveals that 66 ha are allocated in agricultural land, 78 ha in forest land and 38 ha in the barren and cliff land. The results from secondary data and interviews confirm that UTHEP has planned to distribute 10% share to the residents of Dolakha district to promote local level investment. Finally, the study finds that land use planning has very important role for minimizing negative social and environmental effects thus create sustainability of the hydropower projects. It is also found that overall environmental impacts are limited because of technological development such as tunnel and underground powerhouse in UTHEP. The land tenure, Land use planning stakeholders and their role, Governance, policy, social structure etc. are the basic requirements of land use planning for sustainable development of hydropower projects.

Along with the rate of conversion of agricultural land to non-agricultural land, agricultural resources that need to get priority are those for food. The formulation of the problem is: 1) is the implementation of the conversion of agricultural land for housing in accordance with applicable regulations? 2) How is the law enforcement against the violation of the conversion of agricultural land use that is used for housing? 3) What is the ideal concept of law enforcement so that agricultural land conversion does not occur? The type of research used is socio-legal research, which includes primary data and secondary data. The results showed that the regulations regarding the conversion of agricultural land in principle had been implemented in accordance with the applicable regulations, especially regarding the requirements of the conversion of agricultural land. However, there are still violations of the construction of buildings carried out illegally. Law enforcement against violations of land-use change has not been carried out to the fullest, administratively there have been actions taken, but criminals have never been carried out. In the future, law enforcement must consider the reasons for the conversion of agricultural land, whether for public interest or for business ventures.

This study aims to determine the perceptions of the younger generation of agricultural activities in the Buha Sub-District of Mapanget District. This research was carried out from August 2017 to May 2018. Primary data was collected through interviews of 15 generations of young people with the help of filling out questionnaires. Secondary data was obtained from the Buha Village Office, Mapanget District. This analysis uses descriptive analysis. The results of this study indicate that the perception of the younger generation of agricultural activities in the Buha Sub-District is overall negative for agricultural activities. Viewed from internal factors include education, employment, gender and age. The higher the level of education, the wider the insight of the younger generation so that the lack of interest in the younger generation in agricultural activities is getting bigger. The younger generation who already have permanent jobs in the non-agricultural sector look down on agricultural activities because they assume that agricultural activities have a low social level. Women have a low interest in agricultural activities because they assume that agricultural activities are not suitable for women because it will damage their appearance. Respondents aged 21-30 years have a low interest in agricultural activities, in addition to reduced agricultural land. External factors include socialization, parental work status and land ownership status. The younger generation with a low level of socialization results in a lack of interest in the younger generation in agricultural activities. Parents of respondents who work in agriculture or non-agriculture do not want their children to make agricultural activities the main job. The young generation whose parents still own agricultural land is still doing agricultural activities to help their parents work on their farms.
