Abstract

Gastropods are invertebrate animals that have a soft-bodied morphology, mostly shelled, then walk using their stomachs and live only in waters as their habitat. One of the waters used as a habitat for gastropods is the Gorong River. Gorong River is one of the rivers located in Pengadang Village, Praya Tengah District, Central Lombok Regency, which has a fairly high diversity of gastropods. Gastropod diversity can be used as a bioindicator of water pollution. This study aims to determine the species, population, diversity, and abundance of conch (Pilla ampullacea) in the Gorong River, Central Lombok Regency as material for preparing ecological practical instructions. This type of research is descriptive exploratory. Gastropod sampling was carried out at 3 stations using purposive sampling technique. Based on the research results, there were 5 types of gastropods, namely: Melanaides granifera, Pilla ampullacea, Thiara pantherina, Thiara scabra, and Salinator burmana. Dominance index values ​​ranged from 0.154-0.999, diversity index values ​​(Shannon-Wiener) ranged from 0.326-0.807, and the abundance of all snails found in the gorong river in Pengadang Village was 122 snails. Based on the results of the chemical physics parameter assessment at the three stations, which ranged from 270C-330C, current speed 6-30 m/s, depth 9-30 m/s, pH 8.36-8.49, DO 8.03-8.10 mg /L, BOD 5.78-5.00 mg/L, and COD 15.68-15.68 mg/L. The results of the validation of the practicum instructions from the three expert validators were between 68-93 and the student readability test between 60-100 which means very good, so that the preparation of the ecological practicum instructions was declared feasible to use.

Abstract

Processing of plants as medicine or as industrial products is mostly done nowadays, for example in the beauty industry. Rossa damascena is a plant that can be used as a medicinal plant. This flower has many benefits, its essential oil and extract have long been used in body wash products, perfumes, skin lotions and medicines. However, there is not much management and distribution of drugs circulating in the community. The processing of these medicinal plants is a promising matter for pharmacists, because utilizing medicinal plants to be used as medicine can expand the nomenclature of drugs. The method used is the collection and screening of data that has inclusion and exclusion criteria. The results obtained are various information regarding the compound content and its potency contained in Rosa damascena.

Abstract

Nowadays, environmental problems have become a global issue that is widely discussed. Environmental problems that occur are caused by climate change, the extinction of natural resources, to environmental damage caused by human activities. One of the causes of low public awareness of the environment is the low ability of community environmental literacy. One of the efforts to improve environmental literacy is through formal education by implementing learning activities that are able to improve students' environmental literacy skills. Writing this article aims to find out ways or efforts to increase students' environmental literacy in schools with the literature review method, namely, a literature search to collect data from various sources such as journals, books, the internet, and other libraries. Based on the journal reviews that have been carried out, there are several efforts that can be made to optimize or improve environmental literacy in schools, including by structuring the curriculum, conducting learning that provides direct experience supported by active learning using a variety of varied methods and its implementation can be carried out inside or outside outside the classroom, using problem-solving-based learning models, implementing adiwiyata programs, and using interesting learning media.

Abstract

Mangrove ecosystems are important coastal ecosystems that provide a variety of functions. Mangrove ecosystems provide a variety of environmental services including absorbing carbon and contributing to climate change mitigation, protecting coastal areas from storms, tsunamis, and erosion. In addition to providing a variety of environmental services, these ecosystems are also habitats for a variety of living organisms, both aquatic and terrestrial, resident and migrant, also nationally and internationally protected species. The benefits provided by mangrove are contrast to the rate of degradation, which has the potential for loss of wildlife habitat and a decrease in biodiversity value, especially mammals. This study was conducted to analyse the value of biodiversity, especially mammals in the Mangrove Ecotourism Area, Pesawaran Regency. This study uses the method of line transects, mist nets, and sound identification. The results of the study recorded 6 species of mammals with a species diversity value (H') of 1.46, richness of 1.60, evenness of 0.72, and species dominance of 0.30. Mammal species diversity inside the ecotourism area is higher than outside the area. Protected mammals are not found in the area.

Abstract

The mangrove habitat found on the coast of Cemara Beach, West Lombok Regency is a river that meets a forest area that merges with the sea. The objectives of this research include: 1) identifying the types of plants that make up the mangrove forest on the Cemara Coast; 2) analyze the abundance of mangroves on the Cemara Coast; 3) analyze the diversity and evenness index of mangroves on the Cemara Coast; 4) reveal the population of species that dominate the mangrove community on the Cemara Coast; 5) analyze differences in mangrove abundance on sandy and muddy substrates on the Cemara Coast; 6) analyze differences in mangrove species diversity on sandy and muddy substrates on the Cemara Coast; 7) analyze the differences in mangrove dominance on sandy and muddy substrates on the Cemara Coast; and 8) develop research results on mangrove community structure as material in preparing ecological modules. This type of research is comparative descriptive. The design in this research uses a plot method with a total of 20 plots, namely 10 plots on a sandy substrate and 10 plots on a muddy substrate with 1 plot measuring 10 x 10 m. Development research using the 4D model from Thiagarajan et al. (1974) which was modified into 3P (Definition, Design and Development). The results of the research showed that there were 5 species of mangroves found on sandy substrates, while there were 4 species on muddy substrates. The abundance of mangrove plants on sandy substrates is 292 species of Sonneratia alba, while on muddy substrates there are 219 species of Rhizophora mucronata. The diversity index for sandy substrates and muddy substrates is 0, so the diversity index is categorized as low species diversity because H'<1. The evenness of mangrove plants is the uneven distribution of organisms in the community. The species that dominates on sandy substrates is Sonneratia alba, while on muddy substrates it is Rhizophora mucronata. The important value index for the level of poles and trees as well as the level of seedlings and saplings on sandy substrates is included in the medium category, because the important value index value ranges between 101% - 200% which is categorized as medium. Based on the results of the analysis of teaching materials, analysis of expert validation results and student readability tests (small group tests), the average achievement level reached 81.15% with very good qualifications. Thus, the plant ecology module teaching materials are suitable for use without revision.
