Study of settlements carrying capacity in Jebres Subdistrict, Surakarta with das sein – das sollen approach

Abstract

The calculation of the carrying capacity of urban settlements is intended to determine the availability and status of environmental aspects that are utilized by the community. This study aims to examine the availability of environmental support aspects in Jebres District, Surakarta City through the das sein and das sollen approaches. The results of this study indicate that the availability of settlements and supporting aspects in the Jebres District are still able to support the demand for housing in 2018 and projections until 2055. Analysis through the expectation approach (das sein) for 100% decent settlements and the quality of the supporting aspects capable has not been fully realized concretely (das sollen). The availability of green open space (RTH) in Jebres District also does not meet the standards set by the government (30%) where the total area of ​​green open space in Jebres District is 23% of the total. The results of this study are related to the 3rd, 4th and 11th environmental principles. Keywords: carrying capacity, das sein-das sollen, environmental principles, green open space, settlements.

Evaluation of environmental carrying capacity based on land capability for agriculture development in the Melolo Transmigration Area, East Sumba

“…The increasing need and pace of development further encourage changes in land use which have implications for decreasing environmental quality (Wirosoedarmo et al, 2011). As the demand for environmental services by humans keeps increasing, the point of reaching an overloaded environment carrying capacity will be reached if the capacity of these services does not grow in proportion (Fahrurozi et al, 2023). The utilization of natural resources in relation to spatial planning is governed by Law Number 26 of 2007.…”

“…Research on other carrying capacities was conducted by Arcana et al (2021) who conducted an assessment by analyzing population growth, the carrying capacity, and capacity of residential land. In addition, the carrying capacity analysis was carried out by different methods by Fahrurozi et al (2023) with an emphasis on qualitative methods through the das sein (real conditions) -das sollen (expected conditions) approach.…”

“…The presence of carrying capacity plays a crucial role in managing and offering environmental services, which are utilized to fulfill human requirements when it comes to utilizing space as per the Regional Spatial Plan (Fahrurozi et al, 2023). The environmental carrying capacity can be a guide in the use of space for spatial planning so that a safe, comfortable, productive, and harmonious national territorial space exists between the natural environment and the built environment (Suharto et al Surface Slope: A: 0-3% (Flat), B: 3-8% (Sloping or Wavy), C: 8-15% (Slightly Sloping), D: 15-30% (Sloping), E: 30-45% (Rather Steep), F: 45-60% (Steep), G: >60% (Very Steep); 2) Erosion Sensitivity: KE1: 0.00-0.10 (Very Low), KE2: 0.11-0.20 (Low), KE3: 0.21-0.32 (Moderate), KE4: 0.33-0.43 (Rather High), KE5: 0.44-0.55 (High), KE6: 0.56-0.64 (Very High); 3) Erosion Rate: E0: No Erosion, E1: Lightweight (Less than 25% of the top layer is lost), E2: Moderate (25%-75% of the top layer is lost), E3: a Bit Heavy (More than 75% of the top layer to less than 25% of the bottom layer is lost), E4: Heavy (More than 25% of the undercoat is lost), E5: Very Heavy (Ditch erosion); 4) Soil Depth: k0: >90 Cm (Deep), k1: 90-50 Cm (Moderate), k2: 50-25 Cm (Shallow), k3: <25 Cm (Very Shallow); 4a) Top Layer Texture: t1: Subtle, t2: Rather Subtle, t3: Moderate, t4: Rather Rough, t5: Rough, 4b) Undercoat Texture: t1: Subtle, t2: Rather Subtle, t3: Moderate, t4: Rather Rough, t5: Rough; 5) Permeability: P1: <0.5 Cm/Hr (Slow), P2: 0.5-2.0 Cm/Hr (Bit Slow), P3: 2.0-6.25 Cm/Hr (Moderate), P4: 6.25-12.5 Cm/Hr (Rather Quickly), P5: >12.5 Cm/Hr (Quick); 6) Drainage: d0: Excessively Drained, d1: Well, d2: rather Well, d3: Rather Bad, d4: Bad, d5: Very Bad; 7) Pebbles / Rocks: b0: <0.01% (Nothing), b1: 0.01-3% (a Little), b2: 5-15% (Moderate), b3: 15-90% (a Lot), b4: >45% (Very Much); 8) Threat of Flooding: O0: Never, O1: Sometimes, O2: 1 month in a year, O3: 2-5 month in a year, O4: 6 month or more; 9) Salt/Salinity: g0: 0.00.15% Soluble Salt (Free), g1: 0.15-0.35% Soluble Salt (Affected a Bit), g2: 0.35-0.65% Soluble Salt (Moderately Affected), g3: >0.65 Soluble Salt (Greatly Affected).…”
