Production of biogas using the basic substrate of tempeh’s liquid waste and chicken’s waste with the bacteria inoculum of cow’s rumen has been experimentally conducted. This study aims to produce biogas using the substrate with the bacteria inoculum of cow’s rumen and know the optimal mixture ratio of the basic substrate and the inoculum. In this study, the amounts of basic substrate applied were 500 g chicken’s waste and 500 mL liquid waste of tempeh. The study was designed using Complete Random Design comprising 6 treatments with 3 times repetitions, respectively. The treatments tested were P0 (100% basic substrate), P1 (80% basic substrate + 20% inoculum), P2 (60% basic substrate + 40% inoculum), P3 (40% basic substrate + 60% inoculum), P4 (20% basic substrate + 80% inoculum), P5 (100% inoculum). These treatments were fermented with anaerob bacteria for 10 days in the fermentor 1000 mL mounted with the biogas collecting balloon. Variables observed in this study were the measurements of biogas volume, culture medium pH, and biogas burning temperature, and the testing of biogas flame colour. As result of observation, unlike P5, the examined treatments of P0, P1, P2, P3 and P4 could able to produce biogas with the respectively produced volume of 53,6 cm3, 56,7 cm3, 30,0 cm3, 90,0 cm3 and 73,3 cm3. While, the measured values of culture medium pH and biogas burning temperature were 6,23-6,63 and 152oC with the flame of red colour. This study shows that the optimal mixture ratio of the basic substrate and the inoculum for producing biogas is 2:3, and the produced biogas is potential to be used as an alternative energy. Keywords: Biogas, Chicken’s waste, Liquid waste of tempeh, Cow’s rumen

The Black Ant, Dolichoderus thoracicus Smith have long been recognized as a potential biological control agent in Cocoa plantation. The aims of this study were to determine how long D. thoracicus can survive on artificial nests in cacao plantation and to identify the ant competitor of D. thoracicus. The research conducted in three cocoa plantation i.e. Desa Labuan Panimba, Desa Langaleso, and Desa Pantoloan in Donggala District, Sulawesi Tengah. Artificial nest of D. thoracicus made from bamboo and palm leaves smeared with palm sugar solution and then hung in cocoa trees. The black ant, D. thoracicus can be survived for thirty days in the cacao plantation in Desa Labuan but only one day in Desa Langaleso. The weaver ant (Oecophylla smaragdina) and Philidris sp. were identified as the competitors of D. thoracicus ants inside the artificial nests. Keywords: Dolichoderus thoracicus, artificial nests and ant competitors.

These treatments were fermented with anaerob bacteria for 10 days in the fermentor 1000 mL mounted with the biogas collecting balloon. Variables observed in this study were the measurements of biogas volume, culture medium pH, and biogas burning temperature, and the testing of biogas flame colour. Based on the observation result, three of the six examined treatments which could able to produce biogas were P2, P3 and P4 with the respective volume of 160 cm3, 143 cm3, and 118 cm3. While, the measured values of culture medium pH and biogas burning temperature were 6,87-7,10 and 152oC with the flame of red colour. This study shows that the optimal mixture ratio of the basic substrate and the inoculum for producing biogas is 3:2, and the produced biogas is potential to be used as an alternative energy.

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.

This research was carried out in Sidondo Village, Dolo Subdistrict, Sigi Biromaru District, Central Sulawesi Province and Laboratory of Biotechnology, Faculity of Mathematics and Natural Sciences, Tadulako University. This study was aimed to determine an effective biopesticide (active ingredient Aspergillus sp.) which suppresses the growth of P. Palmivora in cacao pod by in vivo state and to stipulate the most affective biopesticide concentration (active ingredient Aspergillus sp.) in suppressing the growth of of P. Palmivora in cacao pod by in vivo state. This This research was by using the methods of Group Random Design (GRD) or Rancangan Acak Kelompok (RAK) consisting of six treatmentsand four repetitions. The observation parameters consist of symptoms of disease, the lenght of infection spots, the infection persentage of P. Palmivora, microscopic observations, in the microscopic of P. Palmivora. The results showed that the biopesticide (active ingredient Aspergillus sp.) was varified as effective in controlling P. Palmivora drawing the rot disease bin cacao plants, by the absent of any symptoms of infection P1,P2,P3,P4 dan P5 treatments. The only treatments in which was infected by P. Palmivora , drawing the rot disease in cacao plants, was P0 with the occurence time of infection symptoms was in the third day after inoculation, the average lenght of infection spots was 8,65 cm and the average infection persentage was 11,60%.
