Abstract

Research on the effectivenes of the test biokompos ?? Trichosubur Protect??on the growth of the cacao plant seeds have been conducted from November 2015 through march 2016 at the cacao gardens hortus Botanicus ( Botanical Garden ) department of Biology, Faculty of Mathematics and Natural Sciences Tadulako University, Palu- Central Sulawesi. The objective is to determine the dose biokompos ? Trichosubur Protect ? which is effective against the growth of cacao seedlings. The study was designed in a compososition of the treament as fllows : P0 ( Basal medium without ? Trichosubur Protect ?),P1 ( Basic medium + ?? Trichosubur Protect ? 10 g), P2 ( basic medium + ? Trichosubur Protect ? 20 g), P3 ( Basic medium + ? Trichosubur Protect ? 30 g), P4 ( Basic medium + ? Trichosubur Protect? 40 g), P5 ( medium Ground + NPK 2 g). Basic media used in the form of a mixture of soil 19 kg + 1 kg of rice husk, put in a polybag 25 x 30 cm 13 kg as the planting of cacao. Parameters include observavation every week; seedling height (cm), number of leaves ( leaf),the girth (mm).observation at harvest inculude: Biomassa (g),leaf weight (g),the weight rod (g), root weight(g),and root dry weight (g). The result shwed that treament P4 ( basic + ? Trichosubur Protect ? 40 g) the treatment is more efeective when seen from the results of last observatoins covering, the everage 29,07 cm plant height, leaf number 40 strands, stem diameter 3,73 cm, weight of leaves at harvest time 12,03 g ( Moisture in the leaves 44,30 g ),weight at harvest stalks of 7,62 g( moisture in the trunk 56,30 g), root weight at harvest 5,93g ( Moisture at the root of 92,80 g), the weight of biomassa when harvested 27,22 g, 4,42 g dry weight of leaf, stem dry weight of 1,98 g, 8,06 g dry weight biomassa.

Abstract

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%).

Abstract

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).

Abstract

Production of biogas using the basic substrate of tempeh?s liquid waste and goat?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. 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.

Abstract

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.

Abstract

Oncobasidium theobromae are fungi that causes disease Vascular Streak Dieback (VSD) on the cocoa plants which can causes a totaly death, because the mechanism attack which systemic. The purpose of this study was to observe the morphology of O. theobromae macroscopically and microscopically, as well as symptoms of VSD attack on the cacao plants. This research was conducted from March to August 2016 in the Laboratory of Biotechnology Department of Biology, Faculty of Mathematics and Natural Sciences, Tadulako University (FMIPA UNTAD). The result of macroscopic observation showed that O. theobromae have white mycelium on the early growth, then the color change to cream and texture like cotton. In microscopic observation, it has branched mycelium and irregular septate. VSD attack symptoms characterized with the leaf has necrosis, the former sitting leaf and the leaf base has three dots, twigs become  toothless and the ends of twigs become dry.
