Abstract

During extensive field surveys in the 2015 year, Eurycoma apiculata A.W. Benn has been found for the first time in the forest reserve of Kenegerian Rumbio, Kampar District of Riau province. This finding is a new record of the medicinal plant in Indonesia. The taxonomic description and photographs of the species are given in this article.

Abstract

Climate change and global warming, caused by increasing carbon concentrations in the air, are the most pressing environmental problems. The loss of forests causes an increase in the air's ability to absorb carbon. If this is allowed to continue, the earth's temperature will increase. On the other hand, environmental pollution continues to increase. This service program aims to provide Education about caring for the school environment. This service was carried out on September 2018. This service stage consists of 6 stages: 1. Observation. 2. Interview. 3. Counseling 4. Practical training on biopori application 5. Planting practice 6. Competition to make posters with the theme of green school activities in schools. From the results of the service it was found that the service activities carried out had provided benefits in increasing students' awareness of caring about the environment. This can be seen from the results of the pre test and post test where there is an increase in understanding of the environment by approximately 40%. From the results of the service, it is recommended to maintain the enthusiasm of students in protecting the environment, especially the school environment, under the guidance of teachers.

Abstract

Tanah ultisol merupakan jenis tanah yang kurang subur dan memiliki masalah dalam aspek fisik, kimia, dan biologi tanah. Salah satu cara untuk mengatasi masalah ini adalah dengan menggunakan biochar dari sekam padi serta pupuk organik cair (POC) yang berasal dari limbah ikan. Tujuan dari penelitian ini adalah untuk mendapatkan dosis optimal pemberian biochar dari sekam padi dengan penambahan POC limbah ikan dalam memperbaiki sifat fisik tanah ultisol. Metode yang digunakan dalam penelitian ini adalah Rancangan Acak Lengkap (RAL), dengan berbagai variasi dosis biochar dan POC limbah ikan. Total terdapat lima perlakuan yang diulang empat kali, sehingga terdapat total 20 unit percobaan. Perlakuan-perlakuan tersebut sebagai berikut: P0 =Tanpa perlakuan; P1 = 25 gram biochar/polybag + 45 mL POC/polybag; P2 = 50 gram biochar/polybag + 45 mL POC/polybag; P3 = 75 gram biochar/polybag + 45 mL POC/polybag; dan P4 = 100 gram biochar/polybag + 45 mL POC/polybag. Parameter yang diamati dalam penelitian ini meliputi warna tanah, tekstur, kadar air, porositas, dan bobot isi. Hasil penelitian menunjukkan bahwa pemberian dosis biochar dari sekam padi dengan tambahan POC limbah ikan dapat memperbaiki karakteristik fisik tanah ultisol, yaitu warna tanah, porositas, dan bobot isi. Berdasarkan hasil penelitian, dapat disimpulkan bahwa dosis terbaik adalah pada perlakuan dengan pemberian 100gram biochar dari sekam padi ditambah dengan 45 mL POC limbah ikan.Kata kunci: biochar, fisik tanah, limbah ikan, ultisol

Abstract

Ecological damage in tropical post-gold-mining areas in Kuantan Singingi Regency, Riau Province, Indonesia is a major concern, with very low pH and high lead (Pb) bioavailability. Therefore, this study aimed to investigate the synergistic effect of dolomite and organic amendments on the phytostabilization potential of Ipomoea aquatica and Amaranthus caudatus under contaminated substrates from Benai, Indonesia. A 28-day mesocosm experiment tested the effectiveness of soil conditioners in immobilizing metals and determining plant uptake kinetics. Applying amendments effectively neutralized soil acidity and optimized the cation exchange capacity (15.01-20.84 cmol/kg), providing favorable rhizosphere conditions for soil stabilization. Pb removal efficiency was high in both species, with a maximum efficiency of 53.51% for Ipomoea aquatica and 53.05% for Amaranthus caudatus by Day 21. Kinetic modeling showed that Amaranthus caudatus reached maximum accumulation earlier (Day 7) than Ipomoea aquatica (Day 14). Moreover, a bioconcentration factor of 0.67–0.69 and a Translocation Factor <1.0 indicated that vertical metal transfer was limited due to uptake by root systems. A biological approach to internal toxicity management was observed, as no significant growth dilution effect was identified by Day 28. Ipomoea aquatica and Amaranthus caudatus are considered good phytostabilizers and candidate pioneer species for large-scale reclamation because they can rapidly immobilize metals and restore ecological buffering with dolomite addition.
