Optimization of settlement land use through carbon footprint approach in The North Balikpapan

Abstract

Limited land in the downtown area as well as the increasing amount of new activities centre causes residential development leads to North Balikpapan. This area is an urban fringe with vast protected forests as buffer zone and catchment area for the city and surrounding area. Land conversion in this area will increase hazard risk of inundation, water quality decrease and increased CO2 emissions. Therefore, development should be maintained environmental stability. One of the rights applicated approach is carbon footprint that is capable to measure the balance between production and absorption needs of CO2 emissions. To find the optimal land allocation, we used carbon footprint calculation from the household activities, identify the factors of settlement growth, and use Linear Programming analysis. Analysis’ results show that settlement activities in North Balikpapan produce 108.362,4 tCO2/year or equivalent with 618,50 Ha green space. Meanwhile, the development of settlement in North Balikpapan is affected by social demographic, developer initiative, environmental condition, public facilities availability, economical structure, and policy factors. According to those factors, optimal allocation of settlement area in North Balikpapan is only about 4,510.01 Ha. With that condition, it still able to absorb CO2 emissions from inside or outside the area around 2.751 tCO2/year.

Optimizing the Potential of Agricultural Land to Maintain the Production Sustainability (Empirical Study at West Papua)

“…It is in accordance with the results of research [5], which states that reduced costs are always zero for optimal solutions. These results are also consistent with a research [15] stating that if the reduced cost value for each variable is zero then all variables have reached the optimal conditions.…”

Optimalisasi Penerapan Kebijakan Zero Delta Q Policy dalam Skala Perumahan di Balikpapan

“…meliputi rumah tipe menengah atas, menengah, dan rumah swadaya penduduk. Pembangunan kawasan perumahan oleh pengembang dan penduduk yang ada di kota Balikpapan ini akan mengakibatkan alih fungsi lahan yang awalnya adalah lahan terbuka menjadi area perumahan (Ghozali et al, 2019). Beralihnya fungsi lahan terbuka hijau menjadi area perumahan akan menyebabkan berkurangnya luasan resapan air hujan (Purwantara, 2015;Recanatesi et al, 2017;Qin, 2020).…”

Evaluation of Carbon Footprint in a Waste Recovery/Recycle Facility

“…The direct carbon footprint refers to carbon dioxide emissions from the combustion of fuels including consumed for heating and transportation purposes. Indirect carbon footprint covers carbon dioxide emissions caused by the entire life cycle of a product from the raw material used in its production to its final disposal [17]. Besides, the carbon footprint is conceptually used as an indicator of global warming potential [12,[16][17][18][19][20].…”

“…Indirect carbon footprint covers carbon dioxide emissions caused by the entire life cycle of a product from the raw material used in its production to its final disposal [17]. Besides, the carbon footprint is conceptually used as an indicator of global warming potential [12,[16][17][18][19][20]. The carbon footprint is usually computed for a specific time period such as 100 years and is expressed in units of mass of carbon dioxide equivalents per unit time or per unit product (i.e.…”
