Abstract

The increased population entails increased food production so that food can be securitized. The root cause of the food security problem is agricultural land use conversion. This study aimed to quantify the paddy field land-use conversion and analyze the driving factors of conversion in the Regency of Bantul. Spatial analysis methods were used based on the satellite image digitization technique and map stacking using ArcGIS software version 10.6; besides, a questionnaire was used to interview the farmers. The questionnaires were analyzed with descriptive statistical methods. The Spatial analysis shows that the Regency has experienced a conversion in its paddy field of 639 ha between 2010–2019. The study has identified that education level, age of farmers, land ownership, land prices, and the distance of rice fields to the road were the factors driving paddy field conversion in the Regency. The regency government needs to incentify the farmers who do not violate sustainable agricultural food land (LP2B). Immediately establish (LP2B) and periodically monitor the area of rice fields using satellite imagery data to know the existence and make appropriate policies.

Abstract

The increased populism should be offset by increased food production; thus, the region's food security can be maintained. Food security will not be resolved if it does not solve the root of the problem, namely the farmers' deterioration and the agricultural land conversion. The primary purpose of this study is to design a dynamic model of sustainable food farming—the methods used in achieving an approach with a dynamic system. Needs analysis, problem formulation, system identification, system modeling, model validation, and implementation are the stages in problem-solving with the systems approach method. The Powersim Studio software analyzes the system and views model behavior. Based on the predicted results, in 2021, Bantul Regency experienced a deficit rice of 1,925 tons without control efforts. A pessimistic scenario with a control policy of 50% of the rice field function transfer rate caused the rice balance sheet to be a deficit of 1,001 tons. Optimistic scenario, control of paddy field conversion 50% of the transfer rate and food diversification obtained rice balance with a surplus of 5,460.24 tons by 2030.

Abstract

Abstract. The Solomeronda River is a water source that currently supplies the clean water needs of the residents of Konawe Regency, with a very useful function for the community, namely for bathing, cooking and as a source of raw water for Regional Drinking Water Companies (PDAM). However, the Solomeronda River is still affected by several community activities that can reduce the quality of river water, such as felling trees and disposing of organic and inorganic waste into river bodies. These community activities will certainly affect the water quality of the Solomeronda River. Purpose: To analyze the status of river water quality through water sampling. Methods and results: Analysis of water quality status was carried out by taking water samples at three stations, namely station I (upstream), station II (middle), station III (downstream) and analyzed in the laboratory with water quality parameters analyzed including physical parameters, chemical parameters and microbiological parameters. The results of water quality measurements were then analyzed using the pollution index method. The results showed that the pollution index of the Solomeronda River at station I was 0.87 (meets quality standards), station II was 0.91 (meets quality standards) and station III was 1.1 (lightly polluted). Conclusion: Overall the pollution index value of the three stations on the Solomeronda River after being averaged has a value of 0.96, it is concluded that the status of the water quality of the Solomeronda River is included in the classification of meeting quality standards (good condition).

Abstract

Alih fungsi lahan sawah terus terjadi, padahal beras adalah makanan pokok sebagian besar masyarakat Indonesia. Oleh karena itu pengawasan lahan sawah sangat penting untuk melihat kondisi terkini. Pemanfaatan citra satelit resolusi tinggi untuk memonitor alih fungsi lahan sawah masih perlu dikembangkan. Penelitian ini bertujuan untuk menganalisis alih fungsi sawah dan melihat hubungan antara nilai tukar petani (NTP) khususnya nilai tukar petani sektor pangan (NTPP) dengan alih fungsi lahan sawah. Metode statistik korelasi bivariate pearson digunakan untuk melihat hubungan NTP dengan alih fungsi lahan sawah. Sedangkan untuk melihat luas alih fungsi lahan sawah digunakan metode analisis digitasi. Sejak tahun 2010–2019 terjadi alih fungsi lahan sawah secara signifikan di Kabupaten Bantul seluas 639 ha. NTP dan NTPP berpengaruh signifikan terhadap alih fungsi lahan sawah. Penyebab rendahnya NTPP adalah harga produksi kian mahal dan harga jual beras/gabah yang murah.

Abstract

The Musi Hydropower-Plant catchment area is susceptible to soil erosion and sedimentation. Therefore, this research aimed to predict land use and land cover changes (LULCC) as well as their impact on soil erosion and sedimentation in the Musi Hydropower-Plant catchment area. The prediction of LULCC was calculated using Land Change Modeler module on IDRISI Terrset, while soil erosion and sedimentation were estimated with the Revised Universal Soil Loss Equation (RUSLE) and Sediment Delivery Ratio (SDR) models. The result showed that forest cover and paddy fields decreased significantly from 18.580 ha and 4.044 ha to 12.907 ha and 2.019 ha, respectively, in the periods of 1993 to 2019 and were predicted to reduce until 2032. Meanwhile, the built-up area and dry agricultural land increased from 818 ha and 2.116 ha in 1993 to 2.229 ha and 5.778 ha in 2019, which is expected to increase until 2032. The estimation of soil erosion rate also gave an increase from 75 t/ha/year to 113 t/ha/year, continuing to reach 122 t/ha/year until 2032. The escalation of soil erosion rate contributed to the change of sediment yield from 68.048 t/year in 1993 to 103.190 t/year in 2019,which is estimated to reach 111.028 t/year. These results are expected to be used by decision-makers and policymakers for the operation of the Musi Hydropower-Plant and the catchment area maintenance.

Abstract

ABSTRAKEvaluasi daya dukung lingkungan merupakan bagian dari upaya mewujudkan pembangunan berkelanjutan. Salah satu metoda evaluasi daya dukung lingkungan adalah evaluasi berbasis kemampuan lahan. Penelitian ini bertujuan untuk melakukan evaluasi daya dukung lingkungan berbasis kemampuan lahan di Tuban, Jawa Timur. Evaluasi dilakukan dengan mengkaji kesesuaian antara kemampuan lahan dengan penggunaan lahan aktual dan alokasi Pola Ruang dalam Rencana Tata Ruang Wilayah Kabupaten. Kemampuan lahan dievaluasi pada setiap Satuan Peta Lahan yang diperoleh dari survai lapangan tahun 2014. Penggunaan lahan aktual dianalisis menggunakan citra Landsat 8 OLI tahun peliputan 2013. Hasil analisis menunjukkan bahwa kemampuan lahan di wilayah penelitian berkisar dari kemampuan lahan kelas II sampai kelas VIII. Wilayah dengan kemampuan lahan yang memungkinkan untuk pengusahaan budidaya (kelas II-IV) mencakup 78,6% wilayah studi, sementara wilayah yang tidak memungkinkan untuk budidaya (kelas V-VIII) mencakup 21,4% wilayah studi. Faktor pembatas kemampuan lahan terdiri dari tekstur tanah, kedalaman efektif, drainase, lereng dan genangan/banjir. Saat ini, 32% wilayah di Kabupaten Tuban penggunaan lahannya sesuai dengan kemampuan lahannya, 66,4% wilayah digunakan melebihi kemampuan lahannya. Dalam hal alokasi lahan pada pola ruang, 67,3% wilayah dialokasikan penggunaan lahannya sesuai dengan kemampuan lahannya, sedangkan 31% dialokasikan melebihi kemampuan lahannya. Temuan ini dapat digunakan untuk mengontrol penggunaan lahan di Kabupaten Tuban dan menjadi bahan revisi Rencana Tata Ruang Wilayah Kabupaten agar penggunaan lahan dialokasikan sesuai dengan kemampuan lahannya.ABSTRACTEvaluation of the environmental carrying capacity should be done as part of sustainable land use planning. One of the method to evaluate carrying capacity is land capability based evaluation. This study aims to evaluate the land capability based carrying capacity of Tuban Regency, East Java Province. Evaluation is done by assessing the conformity between the land capability with current land utilization and land allocation of the Official Spatial Planning of the Regency. Land capability was evaluated for each land unit, which was obtained from soil survey, done in 2014. The current land use is analyzed using LANDSAT 8 OLI imagery of 2013. The results showed that the land capability in research areas was ranged from class III to class VIII. Area with land capability which support the agricultural uses (class I-IV) is 78.6% of total area, while the area which should not be used for agricultural cultivation (class V-VIII) was 21,4% of the total area. Factors limiting the land cability include soil texture, effective depth, drainage, slope, and flood. The area covering 32% of Tuban Regency is used in accordance with land capability, 66.4% is used exceeding land capability. There are 31% of the area that has been allocated in Official Spatial Planning of the Regency exceeds the land capabilities, while 67.3% has been allocated in accordance with land capability. The research result can be used as input to control land utilization in Tuban Regency as well as input for Official Land Use Planning revision.

Abstract

Floods are one of the most prevalent disasters worldwide, including in the capital city of Indonesia. Multi-criteria decision analysis is combined with Geographic Information Systems to produce a mapping of flood hazard areas. The weighting for each parameter is based on six criteria: rainfall, slope gradient, topography, soil type, land cover, and distance from rivers. The flood hazard map is validated using inundation data from the Regional Disaster Management Agency for the years 2015 and 2020. From the general analysis, it can be determined that the parameter most influencing floods is rainfall with a weight of 0.270, followed by slope gradient at 0.164, topography at 0.124, soil type at 0.096, land cover at 0.190, and distance from rivers at 0.155. Therefore, through mapping using QGIS, it is revealed that in 2002, highly flood hazard areas comprised 20.99% of the total Ciliwung Watershed area, which increased to 24.31% in 2020. The validation of the flood hazard map was conducted by recording the coordinate points of flood incidents in 2015 and 2020, revealing that the affected areas within the Ciliwung Watershed occurred in high to very high vulnerability zones. This research demonstrates that flood events in the study area occurred in high to very high flood hazard zones. The results of this study are considered valuable and important for providing accurate information to local governments to develop cost-effective and efficient strategies in dealing with potential flood hazards.

Abstract

Situ Cilodong not only holds excellent tourism potential but also plays a vital role in the water management system of Cilodong District. It serves as a water storage container and a catchment area. According to a 2018 study conducted by the Depok City Government, Situ Cilodong serves various functions, including its potential as a tourist attraction, water resource provider, and flood control. However, these functions are at risk due to several existing problems, primarily pollution. Situ Cilodong's pollution results from various community activities in the catchment area, including the discharge of domestic liquid waste, industrial activities, fisheries, and water tourism. This research aims to assess the water quality of Situ Cilodong. The parameters being measured include temperature, Total Suspended Solids (TSS), turbidity, pH, Dissolved Oxygen (DO), Biological Oxygen Demand (BOD), nitrate, phosphate, Chemical Oxygen Demand (COD), and E. coli levels. The analysis will then be compared to the quality standards set by Government Regulation No. 22 of 2021. The water quality status is determined using the Pollution Index method. BOD parameters ranged from 3.4 – 9.6 mg/L, and E. coli ranged from 1600 MPN/100 ml. Situ Cilodong's Pollutant Index (IP) is 3.34. The results of the water quality analysis indicate that several parameters, including BOD and E. coli, exceed the quality standards. As a result, the water quality status of Situ Cilodong is classified as lightly polluted. So, efforts are needed to maintain and restore the sustainability of Situ Cilodong's water quality.
