This paper discuss about the potential of fungal rot isolates as phosphate-dissolving fungi and their vegetative growth ability on three solid media. All fungal rot isolates were collected from decayed cocoa plants in Bila Village, Pitu Riase, Sidrap District, South Sulawesi. The potential to dissolve phosphate was examined on Pikovskaya broth media and measured using spectrophotometer. The Vegetative ability to grow on solid media was tested on Potato Dextrose Agar (PDA), Malt Pepton Agar (MPA), and Malt Extract Agar (MEA). The results showed that the highest quantitative ability to dissolve phosphate was observed on fungal rot isolate BPB, followed by JT, BPG, and BPE1isolates. MPA medium supported the best mycelial growth compared with others media.

Sugarcane requires land conditions that contain high organic matter to support growth and production. Giving compost from the results of the utilization of the byproducts of sugarcane processing in the form of bagasse and filter mud is expected to increase the sugarcane productivity. The purpose of this study was to determine the effect of compost from the sugarcane bagasse, filter mud and cow manure using the decomposer and Trico Plus mushroom consortium on the growth and production of sugarcane. The experiment was carried out in the form of a randomized block design consisting of eight treatments and three replications. Each treatment was applied as much as 15 tons per hectare, NPK basic fertilizer for all 350 kg treatments per hectare. The results showed that the treatment of compost provides a higher number of sugarcane saplings compared to without the provision of compost. The compost C treatment gave the highest number of sugarcane saplings and the highest number of segments of 7.45 sugarcane saplings and 18.33 segments. Treatment G gave the highest plant height of 283.30 cm, treatment B gave the highest segment length of 15.17 cm, stem diameter of 2.62 cm, stem height of 163.00 cm, sugarcane stem weight of 158.36 kg per plot and 97.655 tons per hectare and POL value 31.32% while treatment E gave the highest Briks value of 23.43%. G treatment gave the best plant height value of 283.30 cm. Giving compost from the results of mixing bagasse, filter mud and manure using the mushroom and Trico Plus consortiums gave better results on growth, and production of sugar cane compared to without the provision of compost.

Global warming is very closely related to carbon stored in an ecosystem. This research aimed to determine the amount of carbon storage in cocoa plantations in East Luwu Regency. The research was carried out in cacao plantation in three districts namely Burau, Wotu and Mangkutana. Measurement of carbon storage was conducted using the allometric formula on an observation plot of 200 m2. Six sampling points were selected consisted of four location with shading trees planted in multistrata agroforestry planting system and two locations with a monoculture planting system. The results of measurements on cocoa plants show that carbon storage increased with the variety of plant species that exist in the cocoa farm. The size of the carbon stocks depends on the planting system. Cacao plantation with multistrata shades system showed carbon absorption of 148.92 tons/Ha that was greater than the amount of carbon absorption in cocoa plantation with monoculture shades system of 50.24 tons/Ha. The level of carbon uptake in East Luwu Regency is 33.19 tons C/Ha. The amount of carbon emissions absorbed is 57.46 t/Ha. CO2 content with the composition of existing land cover in East Luwu Regency is 121.81 tons CO2/Ha.
