Recommendation for Self-Help Housing Stimulus Assistance (BSPS) Recipient Using Multi-Criteria Decision Making Methods

The Housing and Settlement Area Office aims to improve the accuracy and efficiency of selecting beneficiaries for the Self-Help Housing Assistance (BSPS) program by using the Weighted Product (WP) and Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) methods. This study was conducted in Sungkai Tengah Subdistrict, North Lampung, involving six criteria: land ownership, employment, house condition, income, independence, and household size.The WP method is used to determine the weight of each criterion by calculating the product of the criteria values raised to the power of their respective weights, which helps in ranking the alternatives. TOPSIS is applied to identify the best alternative by comparing the geometric distance of each option to the ideal solution, which is either the maximum or minimum value of each criterion The results indicate that the WP and TOPSIS methods can provide more objective and transparent rankings. The application of these methods resulted in the highest ranking for ID V3 with a vector V score of 0.1317. The decision support system developed from this research is expected to assist the Housing and Settlement Area Office in distributing aid more accurately, fairly, and efficiently, thereby supporting the government's goals in improving housing quality and spatial planning

Occupational Exposure of On-Shift Ottawa Firefighters to Flame Retardants and Polycyclic Aromatic Hydrocarbons.

Firefighters can be exposed to complex mixtures of airborne substances, including hazardous substances released during structural fires. This study employed silicone wristbands (SWBs) as passive samplers to investigate potential exposure to polycyclic aromatic hydrocarbons (PAHs) and flame retardants (FRs). SWBs were deployed at different areas of four fire stations, in four truck cabins, and at an office control location; they were also donned outside the jackets of 18 firefighters who responded to fire calls. Overall, office areas had significantly lower PAHs than fire station areas. Vehicle bays and truck cabins had significantly higher concentrations of low molecular weight (LMW) PAHs than sleeping and living room areas. For organophosphate ester flame retardants (OPFRs), tri-n-butyl phosphate (TnBP) and tris(1-chloro-2-propyl) phosphate (TCPP) were detected in all the samples; 2-ethylhexyl diphenyl phosphate (EHDPP) was more frequently detected in the fire station areas. Triphenyl phosphate (TPP) concentrations were highest in the truck cabin and office areas, and tris(1,3-dichloro-2-propyl)phosphate (TDCPP) was highest in truck cabins. Thirteen of 16 PAHs and nine of 36 OPFRs were detected in all the SWBs worn by firefighters, and tris (2-butoxyethyl) phosphate (TBEP) was the predominant OPFR. Levels of LMW PAHs were significantly lower when firefighters did not enter the fire. LMW PAHs, HMW (high molecular weight) PAHs, and EHDPP were significantly elevated when heavy smoke was reported. This work highlights the potential for occupational exposure to PAHs and flame retardants in some fire station areas; moreover, factors that may influence exposure during fire suppression. Whilst firefighters' occupational exposure to PAHs is likely related to fire suppression and exposure to contaminated gear and trucks, exposure to OPFRs may be more related to their presence in truck interiors and electronics.

Pendaftaran Tanah Sistematis Lengkap Tanah tanpa Sertifikat sebagai Upaya untuk Mempercepat Reforma Agraria di Wilayah Kantor Pertanahan Kabupaten Tapin

To achieve nationwide land registration in Indonesia, despite regulatory support, systematic challenges persist in expediting the process known as Complete Systematic Land Registration (PTSL). These hurdles may impede the fulfillment of the mandate outlined in Article 19(1) of Law No. 5 of 1960. The research conducted is of a normative legal nature, focusing on legal norms, aligning with Peter Mahmud Marzuki's definition of legal research as inherently normative. The findings on Complete Systematic Land Registration in the Tapin Regency Land Office Area indicate that unregistered land owners face uncertainty and lack legal protection until their land is officially registered. Although Indonesia's land registration publication system allows for objections or lawsuits, legal certainty and protection are only guaranteed post-registration. The government aims to enhance certainty and protection through the PTSL program, emphasizing the importance of land certificates. However, despite serving as legal evidence of ownership, these certificates are not absolute in legal proceedings and can be subject to civil, criminal, or administrative challenges due to Indonesia's adversarial land registration system.

Revealing the dual impact of VOCs on recycled rubber workers: Health risk and odor perception

Volatile organic compounds (VOCs) pose potential hazards to human health and contribute significantly to odor pollution. This study examined VOC emissions from a representative recycled rubber industry, evaluating the occupational health risks for frontline workers in various workshops. Variables such as gender and workshop-specific concentration variations were considered using Monte Carlo simulation methods. Employees in the five production workshops and office areas face noncarcinogenic health risks with hazard indices (HIs) greater than 1, with the rubber compounding phase presenting the highest risk. Acetaldehyde is identified as the primary noncarcinogenic health risk substance, with hazard quotient (HQ) values exceeding 1 in all workshops. Carcinogenic health risks vary by area, with the highest risks found in compounding and refining workshops. Formaldehyde poses the greatest risk in rubber grinding workshops and offices, with cumulative weights exceeding unacceptable levels of M80.58 % and W77.56 % in grinding and M94.98 % and W92.24 % in the office. Male workers face 4–7 % greater noncarcinogenic VOC health risks than females and 5–14 % greater carcinogenic risks from individual VOCs, increasing their susceptibility to health risks caused by VOCs. Additionally, our analysis of odor identification and intensity classification revealed that 53 VOCs are capable of causing odor pollution, with several substances reaching odor levels of 2 or higher. The predominant perceived odors, as reflected in the odor wheel, include categories such as "solvent/aromatic" and "sweet/fruit," with aldehydes being the primary odor-causing substances. In summary, emissions of VOCs from rubber industrial processes not only pose substantial health risks to workers but also contribute significantly to odor pollution. Consequently, enterprises must prioritize optimizing workplace conditions to ensure the occupational health and well-being of their employees.

Insight into interaction among soil microbial community, soil metabolomics and enzyme activity after long-term PAH stress

The problem of soil polycyclic aromatic hydrocarbon (PAH) pollution in coking plant sites has been widely studied in recent years, but there is a lack of research on the correlation between soil microorganisms, soil metabolomics, and soil properties. Thus, in this study, the long-term impact of coke combustion on soil microbial community structure, enzyme activities, and metabolic pathways within a former coking plant site was investigated. Soil samples were collected from both the coking production area (CA group) and office area (OLA group), approximately 0 to 20 cm in depth. Compared with OLA group, elevated levels of 16 PAHs in the list of USA EPA were detected by gas chromatography-mass spectrometry in the CA group. Several dominant microorganisms, such as Altererythrobacter, Lysobacter, and Sulfurifustis, were identified by 16 s ribosomal DNA sequencing in the CA group. The fatty acid biosynthesis pathway exhibited specific inhibition, while the phenylalanine metabolic pathway was promoted in response to PAH stress. Long-term PAH exposure led to the inhibition of soil urease activity. The co-occurrence network of microorganisms revealed intricate patterns of co-metabolism and co-adaptation within complex bacterial communities, facilitating their adaptation to and decomposition of soil-borne PAHs. This research could provide valuable insights into the community characteristics and metabolic mechanisms of microorganisms inhabiting PAH-polluted soil within coking plant sites. The findings enhance our understanding of the indigenous soil microbiome and its intricate network dynamics under the persistent stress of PAHs, contributing to a more comprehensive knowledge of soil ecosystems in such environments.
