Penerapan Multi Metode Untuk Meningkatkan Sikap dan Hasil Belajar Pencemaran Perairan Siswa Kelas III BP SUPM Sorong

The result of observations on students class 3st TBP (Aquaculture Technology) known to exist of issues cause to the low a studied attitude Water Pollution Control so impact on learning outcomes. The purpose of this research were (1) to know the increase in a studied attitude students after the application of multi methods in learning Water Pollution Control. 2) to know the increase in study results students after the application of multi methods to the process of Water Pollution Control. The research was the act of class resarch (ACR). It was done of students III TBP in application of multi methods on the learning process of water pollution control. The result of research show that 1) on the level of a change in attitude obtained value of 72.03. Based on the scoring reference criteria guide ( SRG) ) scale of five, value of 72.03 show students “ good enough” to changed a studied attitude and 2) on the outcome level student learning obtained value of 72.03 having criteria learning outcomes in the category of “moderat”. This shows that the implementation of multi methods in the learning process of water pollution control to their students 3st TBP enough affect study results.

Screening Life Cycle Environmental Impacts and Assessing Economic Performance of Floating Wetlands for Marine Water Pollution Control

The growing environmental awareness of society, the advancement of nature-based solutions (NbSs), and the need for reliable and cost-effective solutions create a favorable environment of opportunities for floating wetlands as alternative solutions for marine water pollution control. The aim of this work was to screen, through OpenLCA, the environmental impacts of floating wetlands for marine water pollution control at various life cycle stages of the system, and assess its economic performance and contribution to the welfare of society. The stage of raw materials production and acquisition was found to be responsible for the main environmental impacts of the floating wetlands, especially on global warming potential, whereas the main impact of the operational stage was related to the eutrophication potential due to N and P residuals in the effluent. The economic performance indicators of economic net present value (ENPV), economic rate of return (ERR), and benefits/costs ratio (B/C ratio) indicate, although marginally, that floating wetlands may constitute a viable investment with potential positive socioeconomic impacts. However, there are still several scientific challenges and technical issues to be considered for the operational application of such systems at full-scale in marine environments.

2021 Handbook of Florida Water Regulation: Florida Air and Water Pollution Control Act

This handbook is designed to provide a summary of the principal federal and state (Florida) laws that directly or indirectly relate to agriculture. Because these laws are subject to constant revision, portions of the handbook could become outdated at any time. The reader should use it as a means to determine areas in which to seek more information and as a brief directory of agencies that can help answer more specific questions.
