Abstract
Menurut Setiadi et al. (2014) Sengon Solomon (Paraserianthes falcataria (Miq.) Barneby & Grimes) memiliki pertumbuhan yang lebih cepat dibandingkan dengan Sengon lokal (Paraserianthes falcataria). Sengon Solomon selain pertumbuhannya yang cepat juga mempunyai dampak yang positif terhadap tanah kerena daunnya yang lebat dan mudah rontok dapat meningkatkan kandungan bahan tanah serta pada akarnya terdapat bintil- bintil yang mampu bersimbiose dengan bakteri pengikat nitrogen sehingga selain mempunyai manfaat produksi juga bermanfaat meningkatkan kesuburan tanah (Hatmani, 1995). Menurut Cakyayanti dan Setiadi (2011) kegiatan penambangan yang dilakukan dengan metode terbuka (open pit mining) mengakibatkan terjadinya berbagai perubahan pada kondisi lahan, terganggunya tingkat stabilitas lahan, timbulnya berbagai dampak negatif terhadap lingkungan, serta rusaknya ekosistem hutan. Perbaikan pada tanah bekas tambang batubara dapat didukung melalui pemberian kapur dan bahan organik. Tujuan dari penelitian ini adalah untuk mempelajari interaksi antara pemberian kapur dolomit dan kompos kotoran ayam terhadap pertumbuhan tanaman sengon dan bintil akar serta pH tanah bekas tambang batubara. Penelitian ini dilaksanakan di areal bekas tambang batubara PT. Nan Riang pada bulan Juni 2021 sampa Desember 2021. Penelitian menggunakan Rancangan Acak Kelompok (RAK), disusun secara faktorial yaitu, kapur dolomit terdiri dari tiga taraf (0,5x Al-dd,1 x Al-dd, dan 1,5 x Al-dd/ lubang tanam) dan kompos kotoran ayam terdiri dari 3 taraf (1 kg, 2 kg, 3 kg/lubang tanam). Perlakuan diulang sebanyak 3 kali sehingga terdapat 9 kombinasi perlakuan yang diulang sebanyak 3 kali, sehingga terdapat 27 petak percobaan. Dalam petak percobaan terdapat 6 tanaman, sehingga terdapat 162 tanaman. Setiap petak dipilih 4 tanaman sampel secara acak dan sebagai data pada akhir penelitian diambil satu tanaman sampel untuk data pengamatan bintil akar. Hasil penelitian menunjukkan bahwa tidak terdapat interaksi pada pemberian dolomit dan kompos kotoran ayam terhadap pertumbuhan tanaman Sengon solomon dan bintil akar serta pH tanah bekas tambang batubara. Pemberian dolomit dengan dosis 1x Al-dd memberikan pengaruh terbaik dalam meningkatkan pertumbuhan tanaman serta memperbaiki tanah. Pemberian 19 kompos kotoran ayam dengan dosis 2 kg memberikan pengaruh yang nyata dalam pertumbuhan akar tanaman. Kata Kunci : Tanah Bekas Tambang Batubara, Sengon Solomon, Bintil Akar ABSTRACT According to Setiadi et al. (2014) Sengon Solomon (Paraserianthes falcataria (Miq.) Barneby & Grimes) has faster growth than the local Sengon (Paraserianthes falcataria). In addition to its fast growth, Sengon Solomon also has a positive impact on the soil because the leaves are dense and easily fall off which can increase the soil material content and there are nodules on the roots which are capable of symbiotic with nitrogen-fixing bacteria so that in addition to having production benefits it is also beneficial to increase soil fertility. Hatmani, 1995). According to Cakyayanti and Setiadi (2011) mining activities carried out using the open pit mining method result in various changes in land conditions, disruption of land stability levels, emergence of various negative impacts on the environment, and damage to forest ecosystems. Improvements in ex-coal mining land can be supported through the provision of lime and organic matter. The purpose of this study was to study the interaction between dolomite lime and chicken manure compost on the growth of sengon and root nodules and the pH of ex-coal mining soil. This research was conducted in the former coal mining area of PT. Nan Riang in June 2021 to December 2021. The study used a Randomized Block Design (RAK), arranged in a factorial manner, that is, dolomite lime consists of three levels (0.5x Al-dd, 1 x Al-dd, and 1.5 x Al -dd/planting hole) and chicken manure compost consisting of 3 levels (1 kg, 2 kg, 3 kg/planting hole). The treatment was repeated 3 times so that there were 9 treatment combinations which were repeated 3 times, so there were 27 experimental plots. In the experimental plot there are 6 plants, so there are 162 plants. In each plot, 4 sample plants were randomly selected and as data at the end of the study, one sample plant was taken for observation of root nodules. The results showed that there was no interaction in the application of dolomite and chicken manure compost on the growth of Sengon solomon and root nodules and the pH of ex-coal mining soil. Giving dolomite with a dose of 1x Al-dd gives the best effect in increasing plant growth and improving soil. Giving chicken manure compost at a dose of 2 kg has a significant effect on the growth of plant roots.According to Setiadi et al. (2014) Sengon Solomon (Paraserianthes falcataria (Miq.)
