Abstract

Jalan angkut tambang merupakan sarana pentin untuk pengangkutan material. Di PT. Inti Bara Nusalima kegiatan pengangkutan batubara dihentikan saat hujan, karena jalan tidak bisa dilalui alat angkut sehingga perlu perbaikan agar kegiatan pengangkutan dapat berjalan lancar. Perusahaan belum melakukan kajian tentang material jalan dan daya dukung material yang digunakan sebagai jalan angkut. Penelitian ini bertujuan untuk mengetahui klasifikasi material dilakukan dengan Uji Atterberg dengan standar AASHTO dan daya dukung material dengan Uji Dynamic Cone Penetrometer (DCP) untuk mendapatkan nilai California Bearing Ratio (CBR). Berdasarkan hasil analisis ukuran butir material dan uji batas cair dan batas plastis Atterberg, didapatkan bahwa material pada titik 1,2,5,8,9 dan 10 adalah material dengan plastisitas tinggi. Semakin tinggi indeks plastisitas suatu material, maka semakin tinggi potensial pengembangan dari material tersebut. Berdasarkan hasil Uji DCP diperoleh nilai CBR yang beragam dengan nilai CBR tertiggi sebesar 13% pada titik 6 dan nilai CBR teredah sebesar 6% pada titik 7. Berdarsarkan pada pengujian tersebut menyatakan bahwa material yang digunakan pada jalan angkut dikategorikan sebagai tanah dasar sedang sampai buruk, maka diperlukan perawatan jalan yang baik agar material ini dapat bertahan lama sebagai jalan angkut.

Abstract

The majority of farmers in Karya Harapan Mukti Village are independent rubber and oil palm farmers (people's plantations). Generally the strategy used to increase sap production, farmers use synthetic fertilizers (chemical), but it has a negative impact on the environment and soil. The people of Karya Harapan Mukti Village complained about their low competence in agricultural production, only focusing on chemical fertilizers to increase their oil palm or rubber agricultural production. Traditionally, some people know the process of making organic fertilizer, known as compost. But the technology used is still simple, using a derrigen/bucket so that production is still very limited and less efficient. So that technological innovation is needed so that people can produce fertilizers independently, easily and cheaply. The aim of this program is to transfer bioreactor technology innovations to produce liquid organic fertilizer based on local microorganisms from rubber seeds, as well as provide training and competence to the community in processing plantation waste to produce liquid organic fertilizer that can be used to improve plantation quality. One technology that wants to be applied as an Appropriate Technological Innovation (TTG) for the people of Karya Harapan Mukti Village is through the application of bioreactor technology, it is expected to be able to introduce fermentation technology processes to the community and can increase the production of MOL-based liquid organic fertilizer as an effort to meet fertilizer needs in the community. farmers in Karya Harapan Mukti Village, Bungo Regency. Keywords: Rubber, MOL, Fertilizer, Technology
