Abstract

Tanah liat merupakan salah satu bahan utama penyusun semen yang didapatkan dengan cara penambangan. Kegiatan penambangan tersebut dapat menyebabkan kerusakan lahan seperti rendahnya nilai pH tanah. Pemulihan lahan dapat dilakukan dengan cara menggunakan tanaman yang tahan asam, rekayasa lahan dan aplikasi mikoriza. Penelitian bertujuan untuk mengetahui pengaruh berbagai rekayasa media tanam pada pertumbuhan tanaman Jatropha curcas dan mengetahui rekayasa lahan yang optimal untuk pertumbuhan Jatropha curcas. Perlakuan variasi media tanam yang digunakan adalah kombinasi antara tanah taman, tanah bekas tambang dan mikoriza. Setiap variasi media tanam dilakukan 4 kali pengulangan dan diamati selama 12 minggu (60HST). Pengukuran pertumbuhan tanaman berupa tinggi tanaman, jumlah daun, luas daun, biomassa tanaman, rasio tajuk dan akar, Laju transpirasi, Net Assimilation Rate dan Infeksi mikoriza. Hasil data dianalisis dengan uji ANOVA One Way dan dilakukan uji lanjutan dengan uji Post-Hoc Tukey. Hasil penelitian yang didapat adalah semakin tinggi konsentrasi tanah bekas tambang maka semakin rendah tingkat pertumbuhan pada Jatropha curcas. Pertumbuhan tanaman Jatropha curcas yang paling baik adalah pada variasi media tanam tanah bekas tambang 50% + tanah taman 50% + mikoriza. Nilai infeksi mikoriza berbanding terbalik dengan tingkat konsentrasi tanah bekas tambang. Semakin tinggi konsentrasi tanah bekas tambang, nilai infeksi mikoriza pada tanaman Jatropha curcas semakin rendah.

Clay is one of the main components of cement, obtained through mining. This mining activity can cause land degradation, such as low soil pH. Land reclamation can be carried out using acid-tolerant plants, soil engineering, and mycorrhizal application. This study aims to determine the effects of various planting media engineering on the growth of Jatropha curcas and to identify the optimal land engineering for the growth of Jatropha curcas. The treatments involved variations of planting media combinations, including garden soil, exclay mining soil, and mycorrhiza. Each variation of planting media was replicated four times and observed for 12 weeks (60 days after planting). The plant growth measurements included plant height, number of leaves, leaf area, plant biomass, shoot and root ratio, transpiration rate, net assimilation rate, and mycorrhizal infection. Data were analyzed using one-way ANOVA, followed by the Post Hoc Tukey test for further analysis. The results showed that the higher the concentration of exclay mining soil, the lower the growth rate of Jatropha curcas. The best growth of Jatropha curcas was observed in the planting media variation of 50% exclay mining soil + 50% garden soil + mycorrhiza. The mycorrhizal infection rate was inversely proportional to the concentration of exclay minning soil. The higher the concentration of exclay mining soil, the lower the mycorrhizal infection rate in Jatropha curcas.
