Abstract

Mitigation of climate change due to CO2 emissions, the forestry sector developed a REDD+ scheme. This study was conducted to examine financial feasibility of the mangrove rehabilitation with guludan technique, so that further funding of mangrove rehabilitation can be included into REDD+ scheme. Guludan technology was developed to overcome the deep water column for mangrove rehabilitation in the former pond area. This technique has been developed for mangrove species Avicennia marina with spacing 0.25 m x 0.25 m, 0.5 m x 0.5 m, and 1 m x 1 m. Based on diameter and height growth of 36 months planted seedlings of A.marina followed logistic model. CO2 sequestration 386.34 t/ha, 131.12 t/ha, and 26.75 t/ha in 0.25 m x 0.25 m, 0.5 m x 0.5 m, and 1 m x 1 m spacing. With CO2 sequestration selling price of €20,00/t CO2 and rehabilitated land area of 10 ha, this rehabilitation action using guludan technique is not financially feasible, because the criteria for a negative NPV, Net B/C< 1, and IRR < the investment rate, which is 12%. The alternative for this is by implementing material efficiency and increasing carbon selling price as much €54.5/t CO2 for the spacing 0.25 m x 0.25 m; €122/t CO2 for the spacing 0.5 m x 0.5 m; and €580/t CO2 for the spacing 1 m x 1 m.Keywords: Avicennia marina, guludan, CO2 sequestration, plant spacing, and financial feasibility

Abstract

Emissions of motor vehicles containing heavy metals, one of which is lead (Pb). Street vendors belong to the community group at a high risk of exposure to motorized vehicle emissions. This study aims to analyze and assess lead levels in the blood of street vendors. The research design used was cross-sectional with a method of collecting data through observation, interviews, and questionnaires. Lead measurement using the Atomic Absorption Spectrophotometer (AAS) method. The sample was determined by a purposive sampling method of 30 street vendors. The results of this study are 18 respondents (60%) with blood lead levels exceeding normal levels namely <10 μg/dL. The average blood lead level of street vendors was 22,03 μg/dL. The highest blood lead levels were 65 μg/dl with the highest daily working time of 16 hours/day. Characteristics of respondents who have an influence on blood lead (Pb) levels are age and daily work time.

Abstract

Babakan merupakan salah satu desa lingkar kampus yang berpotensi menimbulkan sampah rumah tangga, dimana setiap tahunnya mahasiswa dan pendatang bermukim di Desa Babakan. Pengelolaan sampah yang ada saat ini masih dengan sistem kumpul-angkut-buang sehingga mengakibatkan penurunan kualitas lingkungan pemukiman tersebut. TPS 3R merupakan pengelolaan sampah berbasis masyarakat dengan penerapan Reduce, Reuse, dan Recycle menuju zero waste, yang dapat diimplementasikan di Desa Babakan. Penelitian ini bertujuan untuk mengkaji potensi implementasi TPS 3R pada rumah tangga di Desa Babakan. Metode analisis yang digunakan yaitu, analisis deskriptif kuantitatif yang mengacu pada pedoman SNI 19-3964-1994, analisis deskriptif kualitatif, dan Contingent Valuation Method. Hasil penelitian menunjukkan bahwa total timbulan sampah rumah tangga, tingkat partisipasi dan kesediaan membayar rumah tangga terhadap rencana TPS 3R memungkinkan untuk implementasi TPS 3R tersebut. Biaya operasional TPS 3R dapat dipenuhi walaupun berpotensi adanya free rider.
