Farmers generally plant pepper on ultisol soil. Ultisol soil is classified as acid mineral soil which has a wide distribution, but has the potential to develop agricultural land including pepper plantations. The tendency of land used for agricultural activities shows a decrease in soil fertility, indicated by the occurrence of erosion, imbalance of nutrients present in the soil and stronger soil dependence on fertilizer, as well as lower crop production. The research aims to find out the characteristics of pepper land, productivity, potential land for the development of pepper plants in Muara Badak District. This research was carried out using survey methods with stages including; overlaying land maps, interviews, secondary data inventory, in the form of data on the number of farmers, land area, production and cultivation techniques, and analysis of soil samples in the laboratory. The results showed that the population / ha of pepper plants was different for each farmer, where the spacing was 110 x 110 cm, 120 x 120 cm, 130 x 130 cm and 140 x 140 cm with a population between 1300 - 4500 staples / ha. Farmers generally use lodrin organic fertilizer, but are not carried out intensively, and the land management system does not pay attention to the aspect of soil conservation, farmers' land has been cultivated for generations without using terraces and soil cover. The tendency of nutrient loss on the land is quite high because the land is located on a hill and is quite steep at 16-40% slope. Pepper productivity in the study area is quite high, with an average of 1,437 kg / ha. The highest productivity in Salo Palai village reached 1970 kg / ha, while the lowest in Batu Batu village was 830 kg / ha. The results of soil analysis in the two study locations that the content of the element N was classified as medium, the total K was classified as high to very high. pH and CEC are low, this can affect nutrient absorption, so that lime is needed and the addition of organic matter if fertilization is carried out.

The factors that influence rubber production are planted clones, plant care and tapping techniques. With the right tapping technique, both tapping time, tapping method and mature tapping age, the production potential of a superior clone of rubber plants that has been well maintained can be maintained. The technique of rubber tapping is closely related to the expected level of production, even very determining the age of the tree economy. The research objective was to determine the effect of stimulant better and tapping time on latex production. The method used was a randomized block design with two-factor split plot design. The first factor (main plot) is the time of tapping consists of 3 levels, namely; w1: 05 in the morning, w2: 06 in the morning, w3: 07 in the morning. The second factor (sub-plot), namely the stimulant dosage better consists of 4 levels, namely; b0: control, b1; 0.5 g, b2; : 1 g, b3; 1.5 g. The results showed that stimulate better treatment had a significant effect on latex volume, wet weight and latex dry weight, but was not significant for latex dryness levels. Tapping time was not significant for latex yield, latex volume, wet weight, latex dry weight and highest dry rubber content at 7am. Stimulant Better treatment has a significant effect on latex volume, wet weight, and latex dry weight, but if given at high doses it will reduce the dry content of rubber. The interaction of treatment when tapping and stimulant is better not significant for latex production. The stimulant application better does not exceed the dose of 0.5 g / principal. Doses> 0.5 g / staple will have an impact on the dry tapping field.

Palm oil is an export commodity of the plantation sector which began to develop rapidly in East Kalimantan with an area until 2017 reaching 1,192,342 Ha consisting of 284,523 Ha as plasma / smallholder plants, 14,402 Ha owned by SOEs as the core and 893,417 Ha owned by Large Private Plantation.Empty bunches (Tankos) are solid waste that is produced by palm oil mills in the process of managing palm fruit bunches into crude palm oil (CPO). In each processing 1 ton of fruit bunches will produce Tankos as much as 21-23%. Oil palm empty fruit bunches that are not managed properly will become waste that does not provide benefits. Compost technology using a local microorganism starter (MOL) can be used to produce quality organic fertilizer considering the process involves decomposing bacteria of organic ingredients. Compost technology from tankos waste is very possible to be developed, both at the level of farmers and private oil palm companies. This study aim to determine the potential of palm oil mill effluent (POME) as an bioactivator for composting oil palm empty fruit bunches, and to determine the chemical quality of oil palm empty fruit bunch compost with MOL bioactivator liquid waste as organic fertilizer. Through this research, it is expected that the palm oil mill's liquid waste can be utilized as a bioactivator for compost production and can be applied to the production of oil palm empty fruit bunch compost.This research was conducted for one year. The stages of the research are as follows: 1. Chemical analysis of POME waste, 2. Making LM POME, 3. Chemical analysis of LM POME, and 4. Making EFB Compost, and Chemical Analysis of oil palm empty fruit bunch compost. Compost making using randomized block design (RBD) with 5 treatments and 4 replications include: P0 = 0 ml / liter of water, P1 = 100 ml / liter of water, P2 = 300 ml / liter of water, P3 = 600 ml / liter of water, P4 = 900 ml / liter of water.The analysis showed that there was an increase in the chemical properties of POME after becoming an LM POME activator. Increased chemical properties such as phosphorus from 0.01 to 0.02, potassium from 0.19 to 0.27, and organic carbon from 0.90 to 1.30, but some chemical properties such as pH decreased from 7.20 to 3, 37 and nitrogen decreased from 0.37 to 0.05. The EFB compost analysis results showed that the highest pH was p2 with a value of 8.23, the highest organic C at p4 treatment with a value of 57.65, the highest total N at p3 with a value of 1.80, P2O5 the highest total at p3 with a value of 0.64, and the highest total K2O at p4 with a value of 2.68.
