Abstract. This research is encouraged by environmental issues that occurred recently, so these require a full concern from various fields, including the education field. Environmental education taught from early age will foster young learner's positive attitude towards the environment. Therefore, to deal with these issues, it is required an environmental education learning model that can be used as guidelines by teacher. This research used Contextual-Inquiry Based Learning Model that oriented to child's daily environment. Environmental education should be introduced at an early age, so it is very important to implement Contextual-Inquiry Based Learning Model in kindergarten's Environmental Education. In conducting this research, the planning of Environment Education learning using Contextual-Inquiry Based Learning Modelthe implementation of the Environment Education learning using Contextual-Inquiry Based Learning Model the evaluation of Environment Education using Contextual-Inquiry Based Learning Model The method used is descriptive analytical method. The results in this research revealed that the plan developed by teachers in the implementation of Contextual-Inquiry Based Learning Model in teaching environmental education refers to Regulation of Ministry of  National Education No. 58 of 2009 as well as the local content of environmental education. Implementation of learning was conducted through three main stages, namely the introduction, core and closing. While the assessment was carried out using  techniques and procedures to the characteristics of early childhood and learning needs.Keywords: Contextual-Inquiry Based Learning Model, environmental education, early childhood.Abstrak. Penelitian dilatarbelakangi oleh permasalahan lingkungan hidup yang terjadi dewasa ini, yang memerlukan perhatian dari berbagai sektor termasuk sektor pendidikan. Pendidikan lingkungan yang ditanamkan sejak usia dini akan menumbuhkan sikap positif anak terhadap lingkungan hidup. Untuk itu diperlukan sebuah model pembelajaran pendidikan lingkungan hidup yang dapat dijadikan pedoman oleh guru. Model yang dikembangkan adalah Model Pembelajaran Contextual Teaching Learning (CTL) yang berorientasi pada keseharian anak. Mengingat bahwa Pendidikan Lingkungan Hidup sejatinya ditanamkan sejak usia dini, maka sangat penting kiranya untuk mengimplementasikan model pembelajaran CTL dalam pembelajaran Pendidikan Lingkungan Hidup di Taman Kanak Kanak. Secara lebih khusus  perencanaan pembelajaran Pendidikan lingkungan Hidup dengan menggunakan model  pembelajaran Contextual Teaching Learning (CTL) pelaksanaan pembelajaran Pendidikan lingkungan Hidup dengan menggunakan model  pembelajaran Contextual Teaching Learning (CTL)bagaimana penilaian pembelajaran Pendidikan lingkungan Hidup dengan menggunakan model  pembelajaran Contextual Teaching Learning (CTL) Metode penelitian yang digunakan adalah metode deskriptif analitis. Hasil penelitian menunjukan bahwa perencanaan yang dikembangkan oleh guru dalam implementasi model pembelajaran CTL dalam pembelajaran pendidikan lingkungan hidup mengacu pada Permendiknas No 58 tahun 2009 serta Kurikulum Muatan Lokal Pendidikan Lingkungan Hidup. Pelaksanaan ditempuh melalui tiga tahapan utama yaitu pendahuluan, inti dan penutup. Sementara penilaian dilakukan menggunakan teknik dan prosedur yang relevan dengan karakteristik anak usia dini,  serta kebutuhan pembelajaran. Kata Kunci : pembelajaran Contextual Teaching Learning, pendidikan lingkungan hidup, anak usia dini.

Despite their low performance quality and aesthetics, non-standard bricks are commonly used in the construction of low-rise buildings and rural houses in Indonesia. These bricks are produced traditionnally in home run plants with little adherance to appropriate mix designs. These unfired soil lime bricks enter the market within 2 weeks of production, which inflicts potential loss to the buyers due to their low performance quality. The paper discusses strength improvements of these early age bricks through 2 methods. The first method is by adding the optimal amount of mixing water to the soil and lime mix. The second method is by adding untreated coconut fibers with a 2.5 cm fiber length as additional reinforcements. The effect of 3%, 5% and 7% fiber addition to the mechanical properties of bricks were investigated. Laboratory tests showed that higher compressive strengths, compared to that of traditional unfired soil lime bricks, could be achieved through the 2 proposed methods. The bricks reinforced with higher percentage of untreated coconut fibers have better modulus of ruptures.

Innovators of in vitro meat (IVM) are convinced that this approach is the solution for problems related to current meat production and consumption, especially regarding animal welfare and environmental issues. However, the production conditions have yet to be fully clarified and there is still a lack of ethical discourses and critical debates on IVM. In consequence, discussion about the ethical justifiability and desirability of IVM remains hypothetical and we have to question those promises. This paper addresses the complex ethical aspects associated with IVM and the questions of whether, and under what conditions, the production of IVM represents an ethically justifiable solution for existing problems, especially in view of animal welfare, the environment, and society. There are particular hopes regarding the benefits that IVM could bring to animal welfare and the environment, but there are also strong doubts about their ethical benefits.

The critical need to identify children with hearing loss and provide treatment at the earliest possible age has become increasingly apparent in recent years (Northern & Downs, 1978). Reduction of the auditory signal during the critical language-learning period can severely limit the child's potential for developing a complete, effective communication system. Identification and treatment of children having handicapping conditions at an early age has gained impetus through the Handicapped Children's Early Education Program (HCEEP) projects funded by the Bureau of Education for the Handicapped (BEH).

Abstract. A retrospective suicide study revealed that the Forestry Commission car parks in the New Forest in southern England were a previously unrecognized magnet for nonlocal suicides, attracting as high a proportion of “visitors” (35/43 in 1993-97) as among suicides who jumped from the cliffs at the infamous Beachy Head (39/48 in 1993-97). Over 95% of the car park suicides died from car exhaust gas poisoning. A multiagency initiative aimed to reduce the number of suicides in the 140 New Forest car parks where restricting access was impossible, and environmental issues paramount. Signs displaying the Samaritans' national telephone number were erected in the 26 car parks in which 50% of the car park suicides had occurred. Numbers, location, and residence of all car park deaths were monitored for 3 years. Corresponding changes in other forest registration districts were also monitored. During the 3-year intervention period the number of car park suicides fell significantly from 10/year, 1988-1997, to 3.3/year. The average annual total number of suicides in the New Forest registration district also decreased. No significant changes were found in comparable forest districts. The number of suicides in the New Forest car parks remained low during the 2 years following the evaluation.
