Air Pollution and Lung Capacity of People Living around the Cement Industry

Abstract: Backgrounds: A cement industry is one of anthropogenic sources of air pollution. In polluting the air, the industry creates some dust particles, nitrogen oxide (NO 2 ), sulfur oxide (SO 2 ), and carbon monoxide (CO). Research Purpose: The research aims at finding out the ambient air quality around a cement industry and relating it with the lung capacity of people living around the area. Methodology: This research uses cross sectional studies by measuring the ambient air quality in the morning, noon, and evening in four different settlements within 3 km from the cement industry. The measurement is then correlated with the FEV1 and FVC of lung capacity of people living around the area. Result: Of all four locations, three have ambient air quality (PM 2.5 = 109.47 µg/Nm 3 , TSP = 454.7 µg/Nm 3) that surpass the quality standard (PM 2.5 = 65 µg/Nm 3 , TSP = 230 µg/Nm 3 ). Of 241 respondents, the average level of FVC and FEV1 is respectively 1.9352 liter (SD: 0.45578) and 1.7486 liter (SD: 0.43874). Furthermore, the level of PM 2.5 in the morning and at noon is respectively p=0.009 and p=0.003; the level of TSP in the morning and at noon is respectively p=0.003 and p=0.01; the level of NO 2 in the morning is p=0.006; the level of SO 2 in the morning, at noon and in the evening is respectively p=0.000, p=0.022, and p=0.000; and the level of CO in the morning, at noon and in the evening is respectively p=0.003, p=0.015, and p=0.024. Those levels are associated with the level of respondents’ FEV1. Moreover, the level of TSP in the morning is p=0.024; the level of SO 2 in the morning and in the evening is p=0.007. These levels relate to the level of respondents’ FVC. Keywords: FVC, FEV1, CO, NO 2 , SO 2 , TSP, PM 2.5 , cement industry.

Integrated Analysis of Forest Policies and Their Impacts on Landscape and Lifescape Dynamics: A Case Study in The Walanae Forest Management Unit, Indonesia

Abstract: Abstract In the past few decades, forest policies have caused changes in forest landscape and community lifescape in the study area of Walanae Forest Management Unit (KPH Walanae), South Sulawesi Province. This research aims to analyze forest policy dynamics and their impacts on landscape and lifescape dynamics. We quantify landscape dynamics using land use and land cover change and landscape metrics in interpreting remote sensing results of four data sets obtained in 1990, 2000, 2009, and 2016. Furthermore, we investigate lifescape dynamics using qualitative/quantitative description. We found a rapid land use change in forest landscapes within the past 26 years. A significant change showed that, in 1990–2000, the primary forest that changed into the secondary forest and shrubs has changed into dry land agriculture mix shrubs. The decreased area of the forest brought an increase in economic income for people on one side and large disturbances and forest fragmentation on the other. Various forest policies influenced the forest composition and cover but were insufficiently successful in protecting the natural forest. Results showed that several forest policies that considerably impact the landscape and lifescape conditions include forest land designation, industrial forest plantation, and restoration activities. The policies on establishing KPH and social forest program have not shown the maximum result on the landscape and lifescape improvements and, therefore, must be supported.

Analisis Kesesuaian Perairan untuk Lokasi Budidaya Rumput Laut Eucheuma cottonii di Perairan Kecamatan Sajoanging Kabupaten Wajo

Abstract: Seaweed is the biological resources that have been utilized by people of Indonesia as a livelihood. In some regions, make it as a primary means of livelihood. Eucheuma cottonii or Kappaphycus alvarezii is one type of seaweed that is widely used for farming activities in various Asia-Pacific countries, including Indonesia. Wajo, one area in South Sulawesi that is directly adjacent to the Gulf of Bone. It is strongly supports the maritime field management, one of the potential of seaweed cultivation, especially in Sajoanging District, a newly developed area for seaweed cultivation. The aim of the study is to determine the level of suitability of the waters by physico-chemical conditions for the location of seaweed farming in the waters of the district Sajoanging, Wajo Regency. This research is expected to provide information, which can be used as a reference for the community or regional governments in developing seaweed farming activities in these locations. Physicochemical parameters were measured including tidal, wave, current speed, total suspended solid (TSS), salinity, temperature, nitrate, phosphate, acidity (ph), and depth. The results showed that the district waters of Sajoanging, Wajo Regency was in the category of ‘Not Suitable’ (389.76ha), ‘Quite Suitable’ (1578.43 ha) and ‘Suitable’ (24.32ha) for E. cottoni cultivation. Keywords: Suitable waters , Eucheuma cottonii , Sajoanging, Kappaphycus alvarezii.

Combination of platelet-rich plasma and stromal vascular fraction on the level of transforming growth factor-β in rat subjects experiencing deep dermal burn injury.

Abstract: Introduction The combination of stromal vascular fraction (SVF) and platelet-rich plasma (PRP) is effective at increasing the concentration of growth factors including transforming growth factor-β (TGF-β). The increase in this growth factor is expected to accelerate the healing of burns. This study aims to determine the effect of giving a combination of SVFs and PRP on TGF-β levels in the healing process of deep dermal burns. Methods This was an experimental study in 64 rats using a post-test control group design consisting of 1 group of SVFs and PRP combination injection treatment group, 1 group given a topical combination of SVFs and PRP, 1 group given Vaseline, and 1 control group. Results There was a significant difference in TGF-β levels between the deep dermal burns group that was given a combination of SVFs and PRP injection and topical, the Vaseline group, and the control group with p-value Conclusion The combination of SVFs and PRP increases the level of TGF-β in the healing process of deep dermal burns.
