The beach is an attractive place to unwind from your daily routine. The beauty of the beach must always be maintained so that comfort can still be obtained for everyone who visits it. The beach becomes a comfortable place if cleanliness is maintained. Plastic waste, if any along the coast, can be carried by the waves into the ocean. Plastic waste brought to sea can be consumed by marine biota because marine biota cannot distinguish between plastic and food waste. This community service activity intends to inspire visitors (tourists), managers and traders at Balekambang beach to care about the environment. A well-preserved environment will be a legacy that will be left on the next generation. The survey results show that visitors understand the meaning of waste and are willing to dispose of waste in its place. DOI: https://doi.org/10.26905/abdimas.v5i2.3573

Rice nutrition including vitamin and amylose contents become important aspect for many people around the world. Rice with high amylose content (low glycemic index) is good for those with Diabetes mellitus. Tocotrienol, one precursor of Vitamin-E biosynthesis is catalyzed by enzymes encoded HGGT, while amylose biosynthesis is catalyzed by enzymes encoded GBSSI. The objective of this study was to find rice varieties with high tocotrienol and/or amylose content based on the expression of HGGT and GBSSI among eight Banyuwangi local rice varieties. Relative expression of HGGT and GBSSI was measured by qRT-PCR and analyzed using 2ΔCt method. Statistical analysis resulted in the significantly different of HGGT and GBSSI relative expression among samples. Relative expression of HGGT from the highest to the lowest were demonstrated by Hitam Melik, Hitam Pekat, Blambangan A3, Merah Bali, Blambangan A2, Berlian, Janur Kuning, and SOJ A3, respectively; while relative expression of GBSSI from the highest to the lowest were demonstrated by Hitam Melik, Hitam Pekat, SOJ A3, Janur Kuning, Berlian, Merah Bali, Blambangan A3, and Blambangan A2, respectively. Based on this research we conclude that Hitam Melik potentially produces higher tocotrienol and lower glycemic index than other studied varieties.

Indonesia possesses vast coastal agricultural land areas with high salinity. This high salinity is a threat to rice productivity which may decrease to 79.8%. Banten province of Indonesia houses many local rice varieties which have salinity tolerance potency based on its agronomical characters. The adaptability of rice plant in high salinity soil can be affected by OsDREB2A gene, which encodes transcription factors from several salt-tolerant signaling pathway genes. The aims of this study were to find out the possible polymorphism of OsDREB2A gene from Banten local rice varieties. The polymorphism of OsDREB2A analyzed by Single Nucleotide Polymorphism (SNP) and possible molecular structure. OsDREB2A gene was amplified using DNA from Tambleng, Bulu Putih, and Pare Caok varieties as templates through PCR method with a pair of specific primers. DNA fragments obtained were analyzed by means of series of analysis software. From those analysis we obtained 840 bp, 836 bp, and 850 bp gene fragments from Tambleng, Bulu Putih, and Pare Caok varieties, respectively. There is polymorphism of OsDREB2A due to some mutation yet does not massively alter its protein structure. From this study, we suggest that Tambleng, Bulu Putih, and Pare Caok varieties potential for salinity stress resistance genetically.

Abstract Proteases are ubiquitous enzymes and it can be found in all living organisms. Extracellular proteases have high economic value, where the enzymes can be applied to various industrial sectors. In order to find an alternative source of protease, a search for microbe producing extracellular protease has been done using a selective medium. An extracellular producing bacterium that is identified as Pseudomonas sp has been isolated from chicken feces, that is Gallus gallus bankiva, collected from residential areas at Lowokwaru, Malang, Indonesia. The analysis shows that the bacterium produces extracellular protease with optimum activity after incubation of 66 hours at 35oC. Initial characterization of the extracellular protease shows that the extracellular protease produced by Pseudomonas sp has an optimum activity at pH 12 and an optimum temperature at 39oC. At these conditions, the crude extract enzyme has a specific activity of 0,522 U/mg. The high pH resistance allows its application to variety of industrial processes that require high pH operation. Therefore further studies need to be done to get better understanding of enzyme properties. Keywords: Alkaline protease, Chicken feces, Gallus gallus bankiva, Pseudomonas sp

In the scholarly thoughts, some recognized Muslim scholars are among them: Nashr Hamîd Abû Zayd, Zia Ghokap, Muhammad Syahrûr, Amina Wadûd, and Hassan Hanafî. They were known for their brilliant ideas and theories in perceiving problems and finding ways out of the problems related either to Islamic affairs and the Muslims or even for the welfare of the whole humankind. The ideas that they offered through writings become inspirations and triggers to Islamic development to compete with the West. It is relative to consider one’s idea as extraordinary or ordinary. In this case, Hassan Hanafi, as one of Muslim scholars, tried to offer an idea popularly known as “al-Yasâr al-Islâmî” or “Islamic Left”. The idea proposed in the “Islamic Left” is an effort to bring back Islam and the Muslims to the previous golden era by eliminating every threat to Islam. This revolution is based on three main considerations: revitalization of classical literature, reality of Islamic world and the needs to fight against western civilization.This article is intended to trace the path of the existence of “Islamic Left” developed by Hassan Hanafî from historical background, terminology, school of thoughts, and Hassan Hanafî’s way of thinking.

During critical periods, a child's cognitive, social, emotional, and language development is essential for their growth and development. The development of these skills involves cognitive, emotional and social skills, which are influenced by various factors such as IQ, EQ, SQ and RQ. The utilization of technology in education is an important approach. One of the technologies that can be used is the wordwall application. The utilization of this technology was chosen because when students listen to stories told by the teacher in class through picture storybooks, children do not focus on listening so that the meaning or content in the contents of the storybook that is read is not understood by students. After five to ten minutes, the children are already running around looking for more interesting things. The purpose of this study was to determine the effect of wordwall application on language, social and emotional development of early childhood. The research method used is the experimental method, with a pre-assessment and post-assessment research design, while the type of research is quantitative whose research results are: 1) Wordwall application has an effect on early childhood language development with the results of research p value of 0.016
