Rice bran and coffee waste as a medium and source of nutrients needed for the growth of the white oyster mushroom mycelium (Pleurotus ostreatus (Jacq.) Kumm.). This research has been carried out at Microbiology Laboratory, Department of Biology, Faculty of Mathematics and Natural Sciences, Tadulako University. This study has almed : (1) To determine the growth of white oyster mushrooms (P. ostreatus (Jacq.) Kumm.) in the formulation of rice bran and coffee waste media. (2) Knowing the ratio in the media formulation of rice bran waste and coffee waste that can provide the best growth of white oyster mushroom (P.ostreatus (Jacq.) Kumm.). Data analysis research used in a completely randomized design (CRD), consisting of seven treatments and three replications, namely P1 (100% rice bran), P2 (95% rice bran + 5% coffee waste powder), P3 (90% rice bran + 10% coffee waste powder), P4 (85% rice bran + 15% coffee waste powder), P5 (80% rice bran + 20% coffee waste powder), P6 (75% rice bran + 25% coffee waste powder), P7 (sawdust 70% + rice bran 20% + corn flour 10% (positive control). The results showed that the best mycelium of growth were P7 and P1. The highest number of colonies were at treatment P7 1,26x1012CFU/gr and the lowest was P1 0,26x1012CFU/gr. The fastest incubation time was found in P7, which was 25 days and the lowest was in treatment was P6, 48 days.

Dengue fever is one of the diseases that is still a problem in Indonesia. The incidence of DHF cases in Central Sulawesi, especially Palu City, has increased every year. Environmental and socio-economic factors affect the breeding of Aedes Aegypti mosquitoes. This study aims to determine the effect of socio[1]economic and environmental conditions on the incidence of DHF in the working areas of Sangurara, Bulili and Birobuli health centers in Palu City, Central Sulawesi. The method used quantitative with cross sectional research design. Sampling using Simple Random Sampling technique. The number of samples was 51 cases and 51 controls. Analysis technique used Chi- Square. From the results of the study, the variables that significantly influenced the incidence of DHF were education (p-value = 0.012), occupation (p-value = 1.000), income (p-value = 0.029), frequency of draining containers (p-value = 0.008), habit of hanging clothes (p-value = 0.031), home environment conditions (p-value = 0.005). While the variables that did not affect the incidence of DHF were the availability of lids on containers (p-value = 1.000), and the presence of larvae in containers (p-value = 0.127). This study concluded that education, income, frequency of container draining, habit of hanging clothes and home environmental conditions had a significant influence on the incidence of DHF and there was no influence between occupation, availability of container lids and the presence of larvae in containers.

GRADSTEIN, R. et al. 2010. Bryophytes of Mount Patuha, West Java, Indonesia. Reinwardtia 13(2): 107-123. - This paper presents the results of a two-day survey of the bryophyte flora of Mt. Patuha and its surroundings near Bandung, West Java, carried out in the framework of the 5th regional training course on bryophyte and lichen diversity and conservation organized by SEAMEO BIOTROP, Bogor, in July 2009. A total of 159 bryophyte species were identified, including 98 mosses, 60 liverworts, and 1 hornwort, representing almost 1/6 of the total bryophyte flora of Java. Three moss species, Bryohumbertia subcomosa (Dix.) J.-P. Frahm, Fissidens gymnogynus Besch. and F. polypodioides Hedw., and one liverwort, Lejeunea pectinella Mizut., are new additions to the Javanese flora. The bryophyte diversity of Mt. Patuha is well representative of the Malesian flora and is rich in uncommon species. However, the relatively poor representation of shade epiphytes and commonness of sun epiphytes and generalists reflect disturbance of the forest by anthropogenic activities. Careful attention should be given to conservation of the remaining natural forest in order to prevent further losses of the rich bryophyte diversity of the area

This research aims to determine the growth and production as well as the optimal dosage for white oyster mushroom fruiting bodies on a basic substrate of oil palm empty fruit bunch and sawdust. The study was designed using a completely randomized design (CRD) with seven treatments and three replications. The treatment media consisted of oil palm empty fruit bunch (LSTKKS), sawdust (SG), rice bran (DP), and CaCO3 lime. The treatments were as follows: P1 (LSTKKS 1000 g + Lime 20 g), P2 (LSTKKS 800 g + SG 200 g + DP 100 g + Lime 20 g), P3 (LSTKKS 600 g + SG 400 g + DP 100 g + Lime 20 g), P4 (LSTKKS 500 g + SG 500 g + DP 100 g + Lime 20 g), P5 (LSTKKS 400 g + SG 600 g + DP 100 g + Lime 20 g), P6 (LSTKKS 200 g + SG 800 g + DP 100 g + Lime 20 g), P7 (SG 1000 g + DP 100 g + Lime 20 g). The parameters used in the study included mycelium growth on the substrate, incubation period until pinhead formation, number of pinheads, incubation period until fruiting body formation, number of fruiting bodies, fruiting body morphology, fresh weight of fruiting bodies, and dry weight of fruiting bodies. The results showed that mushrooms could grow on all treatment media, but the best growth and production occurred in treatments P4 with a dosage of 500 g oil palm empty fruit bunch + 500 g sawdust + 100 g rice bran + 20 g lime and treatment P5 with a dosage of 400 g oil palm empty fruit bunch + 600 g sawdust + 100 g rice bran + 20 g lime

he title of this research is The observation of the growth and formation of white oyster mushroom fruit body (Pleurotus ostreatus) on sawsdust and cocoa leaf waste media litter which has been carried out in the Microbiology Laboratory, Department of Biology, Faculty of Mathematics and Natural Sciences. The aim of this research is to determine mycelium growth and formation. Fruting bodies of white oyster mushrooms (Pleurotus ostreatus) on a basic medium of sawdust substituted with leaf litter cocoa. This research was designed in a Completely Randomized Design (CRD) consisting of seven treatments and three replications. The treatment media consisted of sawsdust and and cocoa leaf waste (CLW), namely P1 (sawsdust 500g without CLW), P2 (sawsdust 475g + CLW 25g), P3 (sawsdust 450g + CLW 50g), P4 (sawsdust 425g + CLW 75g), P5 (sawsdust 400g + CLW 100g), P6 (sawsdust 375g + CLW 125g), P7 (sawsdust 350g + CLW 150g) 45g rice bran + 5g lime + 500 ml water were added to each treatment. The best growth in observing the mycelium incubation period until it filled the baglog was in treatment (P2) with a time of 43 days, the best growth in the incubation period until pinheads appeared was in treatment (P1) with a time of 53 days, the best treatment for the number or fruit bodies is in treatment (P5) with a value of 8,67, the best treatment for fresh body weight fruit, namely treatment (P5) with a value of 60,67g. The best treatment for fruit body dry weight was treatment (P5) with a value of 11,33g. The media composition corresponds to the best treatment of the seven treatments, namely P5 (400g sawdust + 100g cocoa leaf litter). Because it has the fastest fruit body incubation. The highest number of fruit bodies and the heaviest fresh weight and dry weight.
