Abstract

Compost is organic material (organic waste) that has undergone a weathering process because of the interaction between microorganisms (bacteria decomposition) that work in it.  Organic materials such as leaves, grass, straw, the remains of twigs, branches and animal waste. In the open nature of compost can occur by itself through a natural process. But   the process lasts for so many years. Therefore the process needs to be accelerated with the help of human. The purpose of this study was to assess the percentage of good natural ingredients for the manufacture of quality compost. The experiment was conducted with single randomized block design (RBD) of compost (lamtoro: lontar fruit fiber: cow manure) with 6 percentage treatment and 4 repeat so that obtained 24 unit of experiment, that is: P1: leaf lamtoro 20% + 30% lontar fruit fiber + 50% cow manure, P2: 30%  leaf lamtoro + 20%  lontar fruit fiber +   50% cow manure, P3: leaf lamtoro 50% + 30%  lontar fruit fiber + 20%  cow manure, P4: 20%  leaf  lamtoro + 50%  lontar fruit fiber + 30%  cow manure,  P5: 30%  leaf  lamtoro  + 50%  cow   manure 20%,  P6 : leaf lamtoro 50% + 20%  lontar fruit fiber + 30% cow manure. Percentage of compost material from leaf lamtoro: lontar fruit fiber: cow manure on treatment P6 shows higher temperature and humidity than other treatments. Results of macro and micro nutrient analysis showed nutrients level from medium to high. The results of the C/N ratio analysis show low result when compared to the C/N ratio level status. Keywords: compost, leaf lamtoro, lontar fruit fiber, cow manure and percentage

Abstract

Local resources isthe rocky dry land have the potential to be developed as productive land if the selection of technology and types of varieties adaptive location.  The problem is the least information abouton the nature of agronomy and the production of  adaptive local corn varieties  at rocky dryland. The study aims to: 1)  gotdata about the agronomic character of  local corn varietiesat  different class  rocky dry land. 2) obtain data about  productive corn on  rocky dry land. Experiment usingRandomizedBlock Designwith 9 replications. Treatment is 3 varieties of maize: 1) Haikesak Putih, 2) Tastim I Putih, and 3) Bunga Merah  Fatumonas. Different conditions of rocks on the surface are different locations. Criteria of a rocky dry land  class consists of Class 2: consists of  rocks that exist on the surface as much as   0.1-3.0% and the small rock is the distance  is about 1 meter. Class 3: consists of  rocks that exist on the surface as much as   3.0%-15% and the small rock is the distance  is about 0,5 meter.Class 4: consists of  rocks that exist on the surface as much as  15-25% andthe small rock is the distance  is about 0,3 meter. Observation variables consist of: 1)Growth: a) Height of plant, b) Diameter of stem, c) Width of Leaf, and 2) Production: a) Weight of maize per plant,   b) Yield per hectare.  The  research results showed   that the local corn varieties of Bunga Merah Fatumonas have the best agronomic at different class of rocky dry land.  The local corn varieties of Bunga Merah Fatumonas provide the best response to: height of plant,  weight of maize per plant,  and  yield per hectare. Key word:  Rocky dry land class, best response
