Illegal gold mining is gold mining activity carried out by gold miners who do not have legal mining permits. The process of illegal gold mining is carried out by the community using a diesel-fueled suction machine, which can cause the air to be polluted by lead so that it pollutes the soil through sedimentation and precipitation processes and must be given treatment to reduce the levels of heavy metals in the soil. The purpose of this study was to analyze local plants that are able to absorb the heavy metal lead (Pb) in the soil. The results of the analysis in this study identified 14 local plant species found in the research location. The three plants with the highest Important Value Indeks (INP) were Phragmites sp. with an INP value of 37.35%, Melastoma sp. with an INP value of 30.64%, and Eleocharis interstincta with an INP value of 25.41%. The highest Pb concentration in the soil was 0.533 mg/kg and the lowest was 0.452 mg/kg. The Pb concentration in the shoots of Eleocharis interstincta was 0.156 mg/kg, in the shoots of Phragmites sp. was 0.106 mg/kg, and in the shoots of Melastoma sp. was 0.074 mg/kg. The Pb concentration in the roots of Eleocharis interstincta was 0.258 mg/kg, the roots of Phragmites sp. 0.309 mg/kg, and the roots of Melastoma sp. 0.162 mg/kg. The BAC, BCF, and TF values of these three plants were 1, which indicated that these three plants were not in the phyto-extractor plant category but were included in the phytostabilization category.

The atmosphere's carbon dioxide (CO2) content raises global temperatures. OGS, or green open space, has the power to absorb carbon dioxide. The OGS of Pinang Masak Campus, Jambi University, too has this potential, although the number of vehicles keeps rising yearly. The reduction of flora at Jambi University's Pinang Masak Campus will result in higher carbon emissions. The three-month study was carried out at the Pinang Masak Campus Jambi University. This study directly measured the crown and counted the number of individual trees. There are 62 species of trees in all, totaling 1455 individuals. Motorcycles are the most common form of vehicle to enter the college area. According to calculations of carbon absorption, the rates of emissions produced by cars, 583,619 kg/hour, and 581,779.330 kg/hour, respectively, are 1,839.667 kg/hour, 583,619 kg/hour, and 581,779.330 kg/hour, respectively. According to these findings, based on positive residual emissions, the Green Open Space of Pinang Masak Campus is less able to absorb carbon emissions from automobiles.

Anthropogenic activities that tend to be exploitative in the mangrove ecosystem of Belawan are thought to have an impact on the biota associated with the ecosystem. One of the impacts is thought to be implied by mantis shrimp Cloridopsis scorpio (Latreile, 1828). The reproductive biology of the shrimp is the main object that needs to be studied in relation to the impacts. This study aims to determine the distribution of gonad maturity stage, gonad somatic index, and the length of the first mature of C. scorpio in the Mangrove Ecosystem of Belawan, North Sumatera. The research was conducted on March to May 2019 with a biweekly sampling period. The purposive random sampling was applied to choose three sampling stations in the research location. Mantis shrimp samples were caught using shrimp trawl. The result showed that the gonad maturity stage of males and females were dominated by Stage I. The gonad somatic index (GSI) range of males were 7.00-10.93 and female were 7.40-11.15. The GSI value of C. scorpio is closely related to its gonad maturity development. The length of the first mature (L50) of males were 205.50±10.65 mmBL and females were 186.0±10.48 mmBL.Keywords: Cloridopsis scorpio, Gonad maturity stage, Gonad somatic indeks, Length of the first mature ABSTRAKAktivitas antropogenik yang cenderung eksploitatif di kawasan ekosistem mangrove Belawan diduga telah berdampak terhadap biota-biota yang berasosiasi dengan ekosistem tersebut.

Crustacea, the largest subphylum in the Phylum Arthropoda, inhabits fresh and seawater. Their bodies are divided into three segments namely cephalo, thorax, and abdominal, or cephalothorax in some crustacean species and they breathe through gills. Crabs are one of the biota that can function as aquatic bioindicators in addition to making a major contribution to nutrient recycling. In the muddy parts of the mangrove forest, the decapod crustacean species Portunidae plays an important ecological function in the environment. This research aims to categorize the crustaceans of the Portunidae family in the East Coast Mangrove Forest Nature Reserve and calculate their dominance, uniformity, and diversity indices. The diversity, uniformity, and dominance index of the Crustacean Family Portunidae in the East Coast Mangrove Forest Reserve area was calculated in this quantitative descriptive research. Purposive sampling is a sampling approach used in survey methods used for sample collection. The results showed that the two different types of crustaceans collected for this study were Thalamita crenata (4125 individuals) and Scylla olivacea (a total 19 individuals). This research shows that in the East Coast Mangrove Forest Reserve area, Thalamita crenata is the most commonly found crustacean species in the Portunidae family. The overall dominance index is in the medium group, while the overall diversity and uniformity index is in the low group. The results of Principal Component Analysis (PCA) show that the environmental factor with the closest relationship and positive correlation between species diversity and uniformity and environmental parameters is salinity.

Air terjun Muara Karing termasuk ke dalam kawasan Geopark Merangin yang menjadi tujuan wisata alam. Hal ini tidak seimbang dengan pengetahuan wisatawan terhadap kondisi lingkungan. Perifiton dapat dijadikan sebagai bioindikator perairan karena sifat perifiton yang mampu merespon bahan polutan. Tujuan penelitian ini untuk mengetahui kelimpahan perifiton pada substrat alami di air terjun muara karing kawasan Geopark Merangin. Penelitian ini dilaksanakan pada Oktober 2022-Juni 2023 dengan menggunakan metode purposive sampling. Hasil penelitian menunjukkan kelimpahan perifiton pada ketiga stasiun (dalam satuan individu/125cm2) berturut-turut yaitu 1.554; 461; dan 490.

The objective of this study is to ascertain the pathogenic and antagonistic fungi that induce disease in avocado plants (Persea americana Mill), identify the antagonistic fungi with the greatest antagonism potential among a variety of antagonistic fungi, and elucidate the mechanism by which antagonistic fungi inhibit the growth of pathogenic fungi. From January to May 2023, this study was conducted in vitro at the Microbiology Laboratory, State University of Malang, employing a completely randomized design (CRD) comprising six replications and four interventions. The identification of mold was accomplished through macroscopically and microscopically descriptive analysis, followed by a comparison with the mold identification key book. The antagonism process was executed utilizing the dual culture method on the PDA medium, and the electron microscope (SEM) was employed to witness the antagonism mechanism. The research findings revealed that T. harzianum spp. and T. viride were identified as antagonist fungi, whereas C. aotearoa and C. gloeospoiroides were identified as pathogenic fungi. The antagonistic fungus T. viride exhibited the greatest degree of antagonism, impeding the growth of C. gloeospoiroides by 77.8%. Observed antagonism occurs when the hyphae of the antagonistic mold ensnare, entangle, and pierce those of the pathogenic mold, causing harm to the region surrounding the pathogenic mold's hyphae and subsequently impeding its growth
