No full textLamun diketahui sebagai salah satu sumber daya laut yang penting karena menyediakan jasa ekosistem laut secara ekologis dan ekonomis. Kondisi lamun di lokasi penelitian telah mengalami penurunan sepanjang tahun 2019; namun belum pernah dilakukan upaya restorasi lamun di lokasi tersebut. Penelitian ini bertujuan untuk mengetahui dan membandingkan nilai kesintasan dan laju pertumbuhan lamun yang ditransplantasi dengan empat metode yang berbeda sebagai upaya restorasi padang lamun. Metode transplantasi lamun yang digunakan pada penelitian ini adalah sprig anchor, bmaboo anchor, pot gerabah dan karung goni. Nilai rata-rata laju pertumbuhan lamun tertinggi didapatkan dari metode sprig anchor sebesar 0,4±0,23 cm minggu-1, sedangkan bamboo anchor, pot gerabah, dan karung goni adalah sebesar 0,1±0,16; 0,2±0,22; dan 0,1±0,06 cm minggu-1. Selanjutnya untuk nilai tingkat kesintasan tertinggi juga didapatkan dari metode sprig anchor sebesar 100%, sedangkan bamboo anchor, pot gerabah, dan karung goni mendapatkan nilai sebesar 80%, 80%, dan 50%. Berdasarkan uji One-Way Anova dan Tukey HSD test, data secara statistik menunjukkan adanya perbedaan yang signifikan. Metode sprig anchor memiliki perbedaan laju pertumbuhan panjang daun lamun yang signifikan dengan metode bamboo anchor dan karung goni, tetapi tidak dengan metode pot gerabah dan metode terbaik adalah sprig anchor.

Seagrass is known as one of the important marine resources because it provides marine ecosystem services both ecologically and economically. The condition of seagrass in the reasearch location has decreased throughout 2019; however, no seagrass restoration efforts have been carried out at that location. This study aims to determine and compare the survival value and growth rate of seagrass transplanted with four different methods as an effort to restore seagrass beds. The seagrass transplantation methods used in this study were sprig anchor, bamboo anchor, earthenware pot and gunny sack. THe average value of the highest seagrass growth rate was obtained from the sprig anchor method of 0.4±0.23 cm week-1, while bamboo anchor, earthenware pots, and gunny sacks were 0.1±0.16; 0.2±0.22; and 0.1±0.06 cm week-1. Furthermore, the highest survival rate was also obtained from the sprig anchor method of 100%, while bamboo anchor, earthenware pots, and gunny sacks received values of 80%, 80%, and 50%. Based on the One-Way Anova test and Tukey HSD test, the data statistically shows a significant difference. The sprig anchor method has a significant difference in the growth rate of seagrass leaf length with the bamboo anchor and gunny sack methods, but not with the earthenware pot method and the best method is sprig anchor
Evaluasi Remediasi Dengan Metode Revegetasi Pada Lahan Bekas Tambang Batu Bara dan Kesesuaiannya Terhadap Konsep Sustainable Remediation (Studi Kasus: PT Arutmin Indonesia Tambang Satui)
No full textIndonesia merupakan salah satu produsen batubara terbesar di dunia, yang memberikan kontribusi signifikan terhadap perekonomian nasional. Namun, aktivitas penambangan batubara menyebabkan dampak negatif terhadap lingkungan. Lahan bekas tambang sering kali memiliki tingkat kesuburan yang rendah, keasaman tinggi, dan kandungan logam berat yang merugikan. Untuk memitigasi dampak ini, remediasi lahan dengan metode revegetasi sering digunakan. Revegetasi bertujuan untuk mengembalikan fungsi ekologis lahan dengan menanam jenis vegetasi tertentu yang adaptif terhadap kondisi tanah yang terdegradasi. Keberhasilan revegetasi tidak hanya diukur dari pertumbuhan vegetasi, tetapi juga dari peningkatan kualitas tanah dan pemulihan fungsi ekosistem.
Penelitian ini berfokus pada evaluasi keberhasilan remediasi lahan bekas tambang batubara di PT Arutmin Indonesia Tambang Satui dengan menggunakan metode revegetasi. Evaluasi dilakukan berdasarkan pedoman yang ditetapkan oleh Kementerian Lingkungan Hidup dan Kehutanan (KLHK) m

Indonesia is one of the world's largest coal producers, significantly contributing to the national economy. However, coal mining activities have severe negative impacts on the environment. Former mining areas often suffer from low soil fertility, high acidity, and harmful levels of heavy metals. To mitigate these impacts, land remediation through revegetation is frequently employed. Revegetation aims to restore the ecological function of the land by planting specific types of vegetation that are adaptive to degraded soil conditions. The success of revegetation is measured not only by the growth of vegetation but also by improvements in soil quality and the restoration of ecosystem functions. This study focuses on evaluating the success of land remediation using the revegetation method at PT Arutmin Indonesia's Satui Mine. The evaluation is conducted based on the guidelines set by the Ministry of Environment and Forestry (KLHK) through Circular No: SE./MENLHK/SETJEN/KUM.1/1/2024. In addtion to assessing technical aspects, this study also considers the alignment of revegetation outcomes with the concept of sustainable remediation, which integrates environmental, social, and economic aspects. The research method used in this study is a descriptive quantitative method combined with a survey. Data is collected through field observations, analysis, and literature review. The results of the study indicate that the success of revegetation, as assessed using the evaluation method based on the Ministry of Environment and Forestry xivRegulation No. SE./MENLHK/SETJEN/KUM.1/1/2024, obtained a score of 87, which falls into the "good" and acceptable category. Secondly, the evaluation based on the aforementioned regulation only assesses the environmental aspect. There is no other evaluation framework from the Government of Indonesia that considers social and economic aspects, either qualitatively or quantitatively. Thirdly, to develop a more comprehensive assessment of remediation uccess, to use the Sustainable remediation Index (ISR), which includes environmental, social, and economic indicators. The weight for each aspect is proposed to be 35% for the environment, 32% for the economy, and 33% for social factors.Keywords : Economy, Remediation, Revegetation, Social, Sustainable emediatio
Identification of biotic and abiotic factors coal mine overburden on Warukin rock formation of South Kalimantan
Get PDFOverburden (the dumping of mine tailings and other reject materials) from the Warukin geological formation is one of the potential acid-forming (PAF) of 33.17%. Mining can cause overburden to be exposed and affect biotic and abiotic conditions. The study aimed to analyze the biotic and abiotic factors of three different age overburdens from the Warukin Formation, South Kalimantan. Biotic factor measurements included vegetation sampling using line transect, soil insects using pitfall traps, and microbial using total plate count. Abiotic factor measurements included air temperature and humidity, light intensity, temperature, moisture, and pH of the substrate (n=3), and chemical overburden. Identification of plants and insect species using information from locals, identification books, and websites. Plant species diversity was analyzed using the Shannon-Wiener Index. Dominance species were analyzed using the Important Value Index (IVI). The relation of overburden age on biotic and abiotic factors was analyzed multivariate with Non-Metric Multidimensional Scaling (NMDS). The results showed that there are 102 species of plants and 11 species of soil insects. The numbers of fungi and bacteria are 10-4 CFU g-1 and 10-3 CFU g-1, respectively. Plant species diversity is classified as medium (H'= 2.34; 2.50 and 2.82). Changes in plant composition occurred as the microclimate and substrate nutrition improved. The organic matter increased over time. Humidity and light intensity influence the presence and composition of organisms, while pH values affect the adaptability of plants, insects, and microbes. Heavy metal concentrations have increased due to the physicochemical properties of the Warukin formation overburden.</jats:p
