ABSTRACTSustainable development urges to merge the three complex dimensions: global economy, global society and physically earth environment. Sachs (2015) states that sustainable development is the expert effort to comprehend the world and the method to solve the crowded earth issues by the global population growth that nine times increase than the first industry era. Education is one of fatal element for sustainable development phase especially for the human (society) development. Human development becomes the main core of invesment for economy development because it is prepared for the youngst as the next generation to develop economic improvement individually for their family and also for their community (include for the State’s development interest). Marshall, Hine and East (2017) studied about the education which develop the autonomous motivation to support individu execute the pro-environmental behaviors (PEBs). This autonomous motivation will establish the environmental attitude and personality in decision making and action of sustainable environment protection and preservation.Keywords: sustainable development, education, pro-environmental behaviors ABSTRAKPembangunan berkelanjutan berupaya untuk mengkaitkan tiga sistem yang rumit yaitu sistem ekonomi dunia, sistem sosial dunia dan lingkungan fisik bumi. Sachs (2015) menyatakan bahwa pembangunan berkelanjutan menjadi cara para pakar untuk memahami dunia dan sebuah metode untuk menyelesaikan permasalahan dunia yang berawal dari sesaknya bumi akibat pertumbuhan penduduk dunia yang sudah mencapai sembilan kali lebih banyak dari populasi manusia yang hidup pada jaman dimulainya revolusi industri. Pendidikan adalah salah satu komponen yang penting dalam proses pembangunan berkelanjutan terutama pembangunan yang terkait manusia (sosial). Pembangunan manusia menjadi bagian vital dari investasi yang dibutuhkan dalam pembangunan ekonomi karena merupakan jalur investasi yang disiapkan untuk anak-anak sebagai generasi penerus yang akan melanjutkan perbaikan ekonomi baik secara individu bagi keluarganya maupun secara berkelompok bagi komunitasnya (termasuk kepentingan pembangunan di Negaranya). Penelitian Marshall, Hine and East (2017) menyatakan bahwa pendidikan dapat membentuk dorongan dari dalam setiap individu untuk melakukan perilaku pro lingkungan hidup (pro-environmental behaviours). Dorongan dari dalam individu ini secara otonomi membentuk watak dan karakter yang ramah lingkungan untuk membuat keputusan dan bertindak yang melindungi dan menjaga keberlanjutan lingkungan hidup.Kata kunci: pembangunan berkelanjutan, pendidikan, pro-environmental beharviors

The Relationship

The aim of this study is to analyse the relationship between vegetation indices of Normalized Difference Vegetation Index (NDVI) and soil nutrient of oil palm plantation at Felcra Nasaruddin Bota in Perak for future sustainable environment. The satellite image was used and processed in the research. By Using NDVI, the vegetation index was obtained which varies from -1 to +1. Then, the soil sample and soil moisture analysis were carried in order to identify the nutrient values of Nitrogen (N), Phosphorus (P) and Potassium (K). A total of seven soil samples were acquired within the oil palm plantation area. A regression model was then made between physical condition of the oil palms and soil nutrients for determining the strength of the relationship. It is hoped that the risk map of oil palm healthiness can be produced for various applications which are related to agricultural plantation.

Recycling is a crucial area of research in green polymer chemistry. Various developments in recycling are driven by Environmental concerns, interest in sustainability and desire to decrease the dependence on non-renewable petroleum based materials. Polyurethane foams [PUF] are widely used due to their light weight and superior heat insulation as well as good mechanical properties. As per survey carried Polyurethane Foam Association, 12 metric tonnes of polyurethane foam are discharged during manufacturing and/or processing and hence recycling of PUF is necessary for better economics and ecological reasons. In present study, rejects of PUF is subjected to reaction with a diethylene amine in presence of sodium hydroxide [NaOH] as catalyst, as a result depolymerised product containing hydroxyl and amine groups is obtained. Conventional and Microwave reaction for depolymerizing polyurethane foam have been carried, and best results are obtained by Microwave reaction. Further depolymerised product with hydroxyl and amine functionalities are reacted with bis (2-hydroxyethyl terephthalate) [BHET] obtained by recycling polyethylene terephthalate [PET] and sebacic acid, with stannous oxalate [FASCAT 2100 series] as catalyst to obtain Polyester amides. These Polyester amides having hydroxyl and amino groups in excess are cured with isocyanates-hexamethylene diisocyanate biuret [HDI biuret] and isophorone diisocyanate [IPDI] for coating applications. The coated films are characterized using physical, mechanical and chemical tests, which shows comparable physical, mechanical properties but alkali resistance is poor.

Splitting System

In recent years, we have experienced extreme climate changes due to the global warming, continuously impacting and changing our daily lives. To build a sustainable environment and society, various energy technologies have been developed and introduced. Among them, energy harvesting, converting ambient environmental energy into electrical energy, has emerged as one of the promising technologies for a variety of energy applications. In particular, a photo (electro) catalytic water splitting system, coupled with emerging energy harvesting technology, has demonstrated high device performance, demonstrating its great social impact for the development of the new water splitting system. In this review article, we introduce and discuss in detail the emerging energy-harvesting technology for photo (electro) catalytic water splitting applications. The article includes fundamentals of photocatalytic and electrocatalytic water splitting and water splitting applications coupled with the emerging energy-harvesting technologies using piezoelectric, piezo-phototronic, pyroelectric, triboelectric, and photovoltaic effects. We comprehensively deal with different mechanisms in water splitting processes with respect to the energy harvesting processes and their effect on the water splitting systems. Lastly, new opportunities in energy harvesting-assisted water splitting are introduced together with future research directions that need to be investigated for further development of new types of water splitting systems.
