The study of observation of growth media formulation of white oyster mushrooms’s mycelium (Pleurotus ostreatus (Jacq.) P.Kummer) on the base with sago pulp supplementation medium was conducted from March to May 2018 at Biotechnology Laboratory, Department of Biology, Faculty of Mathematics and Natural Sciences, Tadulako University. This study were aimed to determine the appropriate formulation and dosage as supplementation of sago pulp with basic media for the growth of the white oyster mushroom mycelium. This study was conducted by Randomized Complete Random Design (RAL), consisted of seven treatments and four replications with basic media and supplementary M0 (100%: without supplements), M1 (95% : 5%), M2 (90% : 10%), M3 (85% : 15%), M4 (80% : 20%), M5 (75% : 25%), M6 (70% : 30%). The results showed that the best growth of mycelium on treatment M0 and M1, mycelium filled the media for 26 days with the average growth of mycelium M0 and M1 were 0,56 cm/ day. The best formulation and dosage of sago suplementation on the base medium were found in M1 (95% base medium: 5% sago pulp).

The Research on formulation of coconut fiber waste and animal manure into biocomposes (decomposer: Aspergillus sp.) has been carried out in Langaleso Village, Dolo Subdistrict, Sigi Regency, Central Sulawesi, Biotechnology Laboratory of the Department of Biology and the Soil Science Laboratory, Faculty of Agriculture at the University of Tadulako Palu, in March to August 2018. The purpose of this research was to formulate the basic substrate (BS) of coconut fiber waste and animal manure supplementation into biocompost using decomposer: Aspergillus sp. The study was designed in a completely randomized design consisting of five treatments and four replications. The treatments arrangement is a comparison of the base substrate of coconut fiber (BS) with animal manure supplements as follows; P0 (BS 100%, without supplements), P1 (BS 90% + supplement 10%), P2 (BS 80% + supplement 20%), P3 (BS 70% + supplement 30%) and P4 (BS 60% + supplements 40%). Parameters of observation include; physical indicators (aroma, color and texture), biology (fungi identification) and chemistry (analysis of C-organic content and nitrogen). The results showed that the P4 treatment showed the best biocompost quality with physical indicators (compost-smelling aroma, black in color and soft texture), biological indicators (identified as Aspergillus sp and Mucor sp contaminant fungi), chemical indicators (40.5% C-organic) , N 1.36% and 29.7%).

The research of biogas aims to obtain an alternative energy source which might replace fossil energy in the future. It was carried out starting from November 2017 to February 2018 in which was located in Langaleso Village, Dolo Subdistrict, Sigi District and in the Laboratory of Biotechnology, Department of Biology, Faculty of Mathematics and Natural Sciences, Tadulako University. The primary substrates were cow dung, chicken manure and the tofu liquid waste by cow rumen as inoculum. The installation of gas-flowed pipes was conducted by using paralon pipes with size ½ dan ¾ inch with the total lenght 8,40 m. The incubation period of the primary substrates was 30 days where the biogas volume quantification was periodically performed in the day of 10, 20, and 30. The results showed that biogas was formed at the incubation day of 10 which hence increase up to the day of 30. The observed gas volume was 223,568 cm3, 368,950 cm3 dan 458,302 cm3 respectively. The results of flame test representing blue flame indicated that the formed biogas contained the content of methane which higher than 70%. This hence revealed that the installation of biogas reactor with the type of “fixed domed plant” equipped by “watertrap” was able to produce a good quality biogas from the primary substrates were cow dung, chicken manure and the tofu liquid waste by cow rumen as inoculum for the application in the household scale.

The study of test for several inoculum formulas on the production of white oyster mushroom body (Pleurotus ostreatus (Jacq.) P.Kummer.) conducted from April to September 2018 at Biotechnology laboratory, Department of Biology, Faculty of Mathematics and Natural Sciences, Tadulako University. This study were aimed to determine whether the treatment of the inoculum formula tested on the production medium can form the white oyster mushroom fruit body and to find out which inoculum formula can form the optimum fruit body in the production medium. This study was conducted by Randomized Complete Design (RAL) consisted of 4 treatments and four replications, I1 (100% corn seeds), I2 (50% : 23%: 27%), I3 (50% : 17% : 33%) dan I4 (95% : 5%). The results showed that I 3 was the best inoculum for the growth of the white oyster mushroom fruit body compared to the other inoculums which were characterized by a wide mushroom hood, the length was long and the weight of fresh mushroom was high. The inoculum formula and the best dosage for body production of white oyster mushroom are found in treatment I3 (50% sawdust + 17% corn flour + 33% bran).

This study aims to know the basic media with sago pulp supplementation which can be formulated into a medium for producing white oyster mushrooms and also to know the comparison of the right media and supplements in the formulation to give maximum oyster mushrooms production. In this study using a comparison with sawdust substrate and sago pulp to see how effective the sago pulp substrate as a supplement media for the oyster mushroom production. the program used is experimental designed in Completely Randomized Design (CRD), consists of three replications so that twelve experiments were obtained. The treatment arrangement is M1: Base media without supplements (controls), M2: 90% base media + 10% sago pulp, M3: 80% basic media + 20% sago pulp, M4: base media 70% + sago pulp 30%. The observation parameters used in the study are mycelium growth, fruit body growth, biological efficiency and measurement of protein levels in the fruit body of the oyster mushroom. The results showed that the addition of sago pulp in the media of oyster mushroom production had no effect on the growth of oyster mushrooms. This can be seen from the media of production of M1 (without the addition of sago pulp) experiencing a higher growth rate of mycelium compared to other treatments. The addition of sago pulp has an effect on the levels of oyster mushroom protein. This can be seen from the protein content of oyster mushrooms in M2 production media which have high protein content. Normal levels of white oyster mushrooms in sawdust media range from 18% -20%. This is due to the mixing of wood powder as a production medium and 10% sago pulp as supplementation to produce more nutrient levels.

Liquid organic ferilizer is fertilizer produced from organic materials, such as weathering food scraps, animals and human organic waste that has been processed, can be solid or liquid. Liquid organic fertilizer contains carbon at 7,1% and a nitrogen content of 3,3%. This studi aims to determine the effect of the horizontal “soil organic” planting system through the application of mustard plants (B. rapa L.) and find out at what dosage the optimum liquid organic fertilizer for the of mustard plants. This studi was designed in a randomized block design with 11 treatments and 3 replication. Treatment arrangement: P0 (whitout fertilizer), P1 (1 mil liquid organic fertilizer), P2 (2 mil), P3 (3 mil), P4 (4 mil), P5 (5 mil), P6 (6 mil), P7 (7 mil), P8 (8 mil), P9 (9 mil) and P10 (10 mil). The result of the study showed the best growth for plant height in P2 with a value of 11,78, for the number of leaves in P2 with a value of 11,20, for the fresh weight of roots in P0 with a value of 2,45, for root dry weight at P6 with a value of 1,1, for plant wet weight in P5 with a value of 15.36 and for plant dry weight in P5 with a value of 1,65.
