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.

Abstract

Tomato fruit waste is fruit that has rotted and eventually becomes waste, often causing problems for the environment, so it is not widely used by the community. Tomato fruit waste can be used as a substitute for EM4 in making solid organic fertilizer, because in tomato waste there are microbes that can help the fermentation process. The aim of this research was to determine the effect of tomato waste and EM4 on accelerating the composting of oyster mushroom baglog waste. This type of research is experimental, namely there is 1 control and 2 treatments with 3 repetitions for each treatment so that 9 experimental plots are obtained. The research design used was a Completely Randomized Design (CRD). Data collection techniques use observation and documentation methods, then analyzed using descriptive methods. This was done to obtain fertilizer indicator data. Measurement of fertilizer indicators such as temperature, aroma, texture, color, pH and humidity. This research was carried out for 14 days and obtained data results which stated that tomato fruit waste was effective as a substitute for the role of EM4 in the process of making solid organic fertilizer, because in tomato fruit waste there are bacteria that help the fermentation process. The conclusion of this research is that the use of tomato fruit waste in the process of making organic fertilizer from oyster mushroom baglog waste produces good quality fertilizer as seen from the results of physical tests which show the characteristics, namely blackish brown color, odorless, neutral pH, humidity 60%-80 %, and the texture breaks down. The results of data analysis on the development of teaching materials showed that the validator score for teaching materials experts was an average of 4.6, material experts had an average of 4, and the public readability test average was 4.1, so that teaching materials in the form of brochures are suitable for use.

Abstract

The development of a science cannot be separated from the development of technology, as well as the development of the theory of evolution as a branch of pure biology which studies the existence of changes in the structure of living creatures which until now continues to experience development. This article uses a literature review approach by examining Darwin's theory of evolution based on the philosophy of science in the study of past, present and future time. Darwin's theory is striking in the excellence of its findings, such as the development of empirical data on an organism, even though it has had many controversies in the development of its science. The results of the study and analysis show that Darwin's theory of evolution can still be used today and is compatible with other existing theories.

Abstract

Specifically, the use of medicinal plants for natural medicine is carried out by the people of Tanah Pinem District, Dairi Regency. There are still some people who use plants as natural traditional medicine, but the people around Tanah Pinem District are currently switching to more modern medicine because it is more efficient. The aim of the research is to identify the types of medicinal plants found in Tanah Pinem District and analyze how much public knowledge there is about the types of medicinal plants used. This research is classified as exploratory descriptive research. In this research, the informants used were 10 people each from 3 villages. 1 resource person is a midwife as caretaker, while the other 29 resource persons are village residents aged ± 40 - 60 years. Data was collected through surveys and direct interviews. The data is then analyzed and then presented through tables and diagrams. The research results showed that people in Tanah Pinem District had sufficient understanding of medicinal plants. The results of the survey carried out found 32 species of medicinal plants used for traditional medicine by the community in Tanah Pinem District, Dairi Regency.
