Abstract

Kegiatan penambangan batubara dengan menggunakan alat-alat berat mengakibatkan terjadinya penurunan produktivitas tanah, pemadatan tanah, erosi dan sedimentasi. Pada lahan pasca tambang pH tanah menjadi sangat masam karena terkontaminasi logam berat. Kondisi ekstrim tersebut dapat diatasi dengan perbaikan kondisi tanah yaitu pengapuran atau penambahan bahan organik, memperbaiki sistem drainase untuk mencegah genangan air, dan penyiraman. Serta pemilihan jenis pohon yang tepat yang dapat beradaptasi dengan kondisi-kondisi ekstrim tersebut. Pemulihan lahan bekas tambang dengan pemberian pupuk organik dan anorganik dapat memperbaiki sifat kimia, fisika, dan biologi tanah pada lahan yang telah terganggu akibat kegiatan pertambangan sehingga sesuai dan berguna untuk kegiatan revegetasi. Pengelolaan tanah dengan pemberian pupuk yang tepat dapat memelihara lingkungan agar tetap berkelanjutan. Tujuan penelitian adalah untuk mengetahui kondisi kualitas tanah setelah diberikan pupuk organik dan anorganik. Serta menganalisis tanah dengan mengamati pH tanah sebelum dan sesudah penelitian. Pemberian pupuk dilakukan dengan 4 perlakuan yaitu perlakuan P0 kontrol (tanpa pupuk), perlakuan P1 (Pupuk Organik 4 Kg), perlakuan P2 (Kapur Dolomit 100 gram), perlakuan P3 (NPK Mutiara 30 gram). Hasil menunjukkan pemberian kapur dolomit memperbaiki sifat kimia tanah dan meningkatkan pH tanah yang semula sangat masam (4,66) menjadi agak masam (6,5), serta berpengaruh terhadap diameter tanaman, sedangkan pupuk organik (kompos Sapi) meningkatkan pH tanah menjadi agak masam (6,2) dan meningkatkan pertambahan tinggi tanaman. Sementara pupuk NPK meningkatkan pH tanah menjadi agak masam 5,8.

Abstract

This study aims to determine the characteristics of pyrolysis durian skin smoke, determine the characteristics of durian skin liquid smoke, and determine the yield of durian skin smoke after distillation. Liquid smoke is obtained from the pyrolysis of soft wood and hard wood, one of which is durian skin, durian skin can be used as a raw material in the manufacture of liquid smoke, Besides durian skin contains cellulose, hemicellulose and lignin compounds which are chemicals that form components of liquid smoke. One way to obtain the desired organoleptic properties is by distillation treatment, so it is hoped that the distillation method can produce higher quality liquid smoke as a preservative that is cheap and safe for health. Parameter values ​​of refractive index and pH of durian peel liquid smoke Pyrolysis results are greater than after distillation, except for acetic acid which is smaller. The refractive index value is 1,3572, the pH value is 4,901, and the acetic acid value is 6,172 N. The refractive index and pH values ​​of the distillated durian skin liquid smoke are smaller than those of pyrolysis, except that the acetic acid value is greater. The average value of the refractive index is 1,23467-1,34800, the pH value is 3,44067-2,51600, and the value of acetic acid is 7,37533-7,97600 N. The effect of temperature and distillation time affects the yield value of the resulting liquid smoke. The temperature and time of distillation affect the value of the volume of the distillation result. The higher the distillation temperature and time, the greater the yield. The best treatment is temperature 3 (150oC) and time 3 (90 minutes) of 84.66%.
