Abstract

Seagrasses are plants in the marine environment and have a vital function for the survival of organisms. This study aims to describe the indicators of the seagrass ecological function of the diversity of echinoderms species. The research method used is the method of line and square transects. Data analysis uses analysis of abundance (Ki), diversity (H ') Shannon Wieners, Morisita Dispersion Index, and Jaccard Index. The results showed that the highest seagrass species found at Lungkak beach were 8 species and the lowest was in the Mangrove Poton of 6 species. Furthermore, the number of species of Echinoderms found was 14 species, and the species with the highest abundance was Diadema setosum with a value of 1.21 Individual / m2, and the species that had the lowest abundance was Holothuria scabra) with a value of 0.01 Individual / m2. Meanwhile, the location with the highest value H 'is in Gili Kere with a value of 1.76, and the location with the lowest value of H' is in Lungkak with a value of 1.01. Furthermore, the value of the Seagrass Morisita Dispersion Index and Echinoderms in the study area had a uniform and grouped pattern. The quantitative and qualitative values obtained are a form of seagrass ecological contribution to the sustainability of Echinoderms in the study location. Therefore, the results of this study can be a scientific basis for the importance of the existence of seagrass beds, especially for the sustainability of marine life such as species of Echinoderms.

Abstract

Asphalt concrete wearing course is laid on the top of road pavement so that directly exposed to ultra violet light and other environment impact. The higher temperature at the pavement surface and exposure to atmospheric oxygen accelerated aging cause asphalt to stiffen and become brittle. This aging result decrease the binding of asphalt and aggregate leads various damage of pavement. The aged asphalt rejuvenated and recycled with rejuvenating agent has been developed to reduce the use of virgin material for road maintenance. This article aims to review durability of asphalt concrete wearing course using waste cooking oil, epoxy resin, kerosene and waste engine oil as asphalt rejuvenators. Aging asphalt was prepared by heating in an oven at 85 oC for 120 hours (long term oven aging). Durability was assessed from the value of Marshall immersion which represent the resistance of asphalt mixture at water immersion. Relation between Marshall immersion and voids in mix (VIM), voids in the mineral aggregate (VMA), voids filled with bitumen (VFB) and density are also evaluated. From the analysis, it can be concluded that the use of waste cooking oil, epoxy resin, kerosene and waste engine oil as asphalt rejuvenators increase the durability of asphalt mixture containing the aged asphalt.

Abstract

This study aimed to determine the growth responses and yield of carrot (Daucus carota L.) grown at the lowland at various rates of biogas solid waste and media volumes. The experiment was carried out at Mataram University experimental field in Narmada, West Lombok, NTB with an altitude of 136 m above sea level, from April to July 2019. The experiment was designed according a factorialy Randomized Completed Block Design (RCBD). The first factor consisted of 4 volumes of the media which i.e: 2000 cm3/20 x 20 cm, 4000 cm3/25 x 25 cm, 5000 cm3/30 x 25 cm and 7000 cm3/30 x 30 cm. The second factor consisted of 3 levels of biogas solid waste (bio-slurry) with i.e: 10 tons/ha, 15 tons/ha, and 20 tons/ha. These two factors were combined resulted in 12 treatment combinations. Each treatment was repeated so there was 36 experimental units each with replicate. The results showed that the rates of bio-slurry affected the rate of increase in carrot leaf length and did not significantly affect the other parameters or yield of carrot plants in the lowlands. Rates of 10 tons/ha and 20 tons/ha produced a higher leaf length than 15 tons / ha. The media volumes influenced the rate of increase in leaf length, rate of increase in the number of leaves, plant fresh weight, dry tap root weight and tap root length. The media volume of 5000 cm3 and 7000 cm3 resulted higher growth and yield of carrot plants in the lowlands rates of the media volume of 2000 cm3 and 4000 cm3. There was no interaction between the bio-slurry rates and the media volumes in influencing the growth and yield of carrot plants in the lowland

Abstract

The research was conducted on the researcher's curiosity on various environmental problems that arise as a result of the condition of the earth that is no longer able to sustain all the needs and desires of humans are infinite. But to avoid too much discussion, research will focus on how coal's role in contributing to high levels of air pollution in India. Air pollution is one of the environmental problems that often gets the world's attention. Talking about air pollution must be very closely related to the State of India, whose position as the country with the worst levels of pollution in the world. The method in this study uses a type of qualitative method with the source of data in the form of a literature review that is journal articles that have relevance to the research topic. The data obtained through the literature review will then be carried out data analysis with data reduction stages, data presentation and drawing conclusions. Based on the results of the study it can be seen that coal is the belle of fuel used by India as a support for the large energy needs of Indian society. Indeed, coal's natural resources have a positive impact on the economic situation and conditions of energy security in India, but there are more urgent things that need attention that is related to the negative impact of coal use in the form of pollution which is very dangerous for the survival of Indian society. Therefore, to protect the public from the worsening air conditions in India requires serious efforts from various groups, especially the government

Abstract

Nusa Penida is part of the Province of Bali which consists of three small islands, namely Nusa Penida Island, Nusa Lembongan and Nusa Ceningan within the administrative area of Nusa Penida District, Klungkung Regency. The development of tourism in Nusa Penida has increased access to physical development and supporting facilities for the region. The leap of development of tourism facilities began to be felt starting in 2005, namely on the islands of Nusa Lembongan and Nusa Ceningan. The development of massive tourism facilities took place in 2015 until 2019 since the 2014 Nusa Penida Festival was held. Many coastal and inland areas were built with tourism accommodation, which naturally led to land conversion and land depreciation. The purpose of this study was to determine land use change from 2003 to 2019 using the overlapping analysis method of Google maps and maps derived from quick bird imagery. Transfer of land functions in the Nusa Penida Region from 2003 to 2019 reached 164.84 ha or the rate of land use change that occurred in the Nusa Penida Region was 0.85%.

Abstract

 Bioconversion is one of the ways to treat organic waste (market abundance) which is a problem today, namely by utilizing microorganisms such as Black Soldier Fly (BSF) larvae as biodegradation agents. This study aims to study the life cycle of BSF in market waste media and to determine the potential of BSF larvae to break down market waste. This research was conducted for 8 months starting from the pre-study until the implementation of the study. The observation phases carried out in this study included 1) the life cycle of BSF in the chopped and non-chopped organic market waste media. 2) the potential of BSF larva / maggot in breaking down chopped and not chopped organic market waste. The results showed that the hatching process from eggs to larvae took three to four days. The larval phase which is still yellowish white lasts approximately 12 days, in this phase the larvae will need a lot of food. The prepupa phase occurs from the 19th day and the pupal phase is 100% achieved on the 24-26th day. Maggot has the ability to degrade market waste up to 84 ± 4.90% in market waste that is enumerated and around 69 ± 5.83% breaks down market waste that is not chopped
