    Abstract Biocomposite is a composite material that uses natural materials that contain lignocellulose. The manufacture of composite boards by utilizing agricultural waste will get added value, namely reducing the impact on the environment. Biocomposites that utilize the mycelium of white rot fungi, namely Auricularia auricula and Lentinus squarrosulus as binders and lignocellulosic materials such as sawdust and wood chips which contain the main components of cellulose, hemicellulose, and lignin which are good for fungal growth. The purpose of this study was to determine the effect of the type of white rot fungus with lignocellulosic material composition and to determine the optimal type of fungus and lignocellulosic material on the manufacture of biocomposites. This study used an experimental method with a completely randomized design with 10 treatments with 3 replications, the treatment was carried out on lignocellulosic materials in the form of sawdust and wood chips with a composition (25%, 50%, 75%, and 100%). The research variables consisted of independent variables in the form of white rot fungi and wood species, while the variable was the quality of the resulting biocomposite material. The parameters measured in this study were the main parameters, namely fungal mycelium growth, composite density, composite air content, composite thickness expansion, modulus of elasticity and modulus of fracture of the composite. The supporting parameters are composite biodegradability. The results showed that the types of fungi and lignocelluloic materials had an effect on the manufacture of composite boards.

    Batik effluent had high toxicity to aquatic organisms. Dye decolorization is a process used to reduce color density. Fungi which used for decolorization was Aspergillus sp 3. This study aimed to investigate the ability of fungi on decolorization of 3 kinds of batik effluents (Indigosol Green dye, Indigosol Purple dye, and Naphtol Black dye) and to investigate the ability of fungi on reducing TDS level. The study was also investigated the initial toxicity of batik effluents to Goldfish (Cyprinus carpio). Decolorization was measured by spectrophotometry, the pH value was measured by pH meter, and the TDS value was measured by TDS meter. In addition, the decolorized batik effluent was tested for toxic effect on C. carpio by total opercular beats. Decolorization assay showed that Aspergillus sp. 3 had the ability to decolorized only 2 kinds of batik effluents. The decolorization percentage of Indigosol Purple was 60.015% and Naphtol Black was 56.679%. The pH after treatment decreased from 8.5–9 to 5.3–6. The range of pH value of Indigosol Green, Indigosol Purple, and Naphtol Black 5.3–6. Besides that, Aspergillus sp. 3 also had the ability to reduce the TDS level in the effluent. The TDS level on Indigosol Green, Indigosol Purple, and Naphtol Black as 4,965%, 25,307%, and 15,129%, respectively. Initial toxicity assay of effluent to C. carpio showed that there was a difference of total opercular beats, which exposed by decolorized and before decolorized batik effluent. The total opercular beats of C. carpio on decolorized batik effluents showed high value than before decolorized batik effluents. It can be concluded that Aspergillus sp. 3 had the ability to decolorize and decreasing the initial toxicity of Indigosol Purple batik effluents on C. carpio

    The high coverage rate of handling partially rejected claim financing reaching 7.34% of the total 19,476 cases in the Outpatient Unit of the Jambi Provincial Mental Hospital (RSJD) in 2022, is closely related to the quality of human resources (HR) in this case, the claims officer and the suitability of what is done with the job description, job specifications and standard operating procedures (SOP) that have been made. This study aimed to analyze the position of administrative officers and claim verifiers in the outpatient unit of the Jambi Provincial Mental Hospital. This research used a qualitative method. Information was collected through in-depth interviews with eight informants, observation, and document review. Test validity by triangulating sources, techniques, and data. The results showed that officers already knew the claims administration and verification procedures. The claim administration SOP in this case, the RJTL claim submission SOP and the monthly reporting SOP have not been outlined in a decision letter for the coding SOP. However, it has been outlined in a decision letter but has not been adequately socialized to the officers concerned. The SOP for claim verification has not been outlined in a decision letter and still refers to the technical guidelines for claim verification issued by BPJS Health. It is still found that the delegation of tasks and the number of verification officers not following the calculation of workload and standards set are obstacles in implementing administration and verification of claims in the Jambi Province RSJD outpatient department

    Biosorption has been known as a potential method in reducing heavy metals and dyes in wastewater, including chrome (Cr) and dyes contents of the wastewater from the batik industry. Straw and spent mushroom compost (SMC) are potential biosorbents due to cheap, abundant, and easily obtained. However, the effectivity of the biosorbents is not only depended upon the type of material but also their surface area. In this study, a modified tea bag was used to increase the surface area of the straw and spent mushroom compost to absorb Cr and dyes from the batik industry wastewater. The optimum of biosorbent ratio and pH in Cr absorption and dyes decolorization was measured. This experiment was conducted using Spilt Plot Design. The results showed that the highest Cr absorption was found at 0,0050 mg/g, and the percentage of decolorization was 68,92% in the biosorbent ratio of 3:1 and pH 5. Biosorbent packed in the tea bags modification was effective removes Cr and dyes in the batik industry wastewater

One strategy to control these problems by using Arbuscular Mycorrhizal Fungi (AMF). This study aimed to determine the effect of AMF inoculum on the growth of maize plants and to determine the optimum dose of AMF on maize plant growth using ex-mining soil as a planting medium.This research used an experimental method with a completely randomized design (CRD) with 4 doses of AMF (0, 100, 150, 200 g) by using ex-coal mined soil medium which consisted of  three repetition. The independent variable was the dose of AMF and the dependent variable was the ability of AMF to infect roots. The main parameter observed was the degree of root infection, while the supporting parameters were plant dry weight, number of leaves and height of corn plants. Data were analyzed using Variance Analysis (ANOVA) test with a standard error of 5% and tested with Honestly Significant Different (HSD). The results showed that the AMF dose treatment on the ex-coal mined land had an effect on the growth of corn plants at 42 days after planting. AMF has a positive effect on the growth of corn plants. The dose of 100 g/polybag is an effective dose to increase the growth of corn plants on ex-coal mining soil. The dose of 200 g/polybag gave the best results on plant height, number of leaves and dry weight of corn plants

    White rot fungus species such as Trametes sp. have been known to  able to decolorize azo dyes, heterocyclics, and reactive or polymeric compounds through the degradation of ligninolytic enzymes. Decolorization membrane is a medium that used as a means to reduce waste, one of which is batik waste. The decolorization membrane is made in a certain form by functioning as a growth medium for fungal mycelium which is used as an alternative in bioreactors. The main ingredient for making decolorizing membranes is sawdust. Other materials needed are supplements such as lime (CaCO3), gypsum (CaSO4), and water. This study used an experimental method with a completely randomized design (CRD), with 5 treatments and each with 5 replications. The results showed that differences in the composition of the organic matter media affected the growth of the mycelium of the fungus Trametes sp. Differences in the composition of each treatment showed significant results. Further test data showed that the composition of P3 was the optimum membrane medium for the mycelium growth of the fungus Trametes sp. with a composition of 65% sawdust, 15% rice bran, 5% lime, 5% gypsum, and the addition of 10% milled corn. The results also show that the nutrients contained in the media can affect the growth of mycelium. The addition of the composition has a good effect on the growth of the mycelium as long as the composition is calculated correctly.Spesies jamur pelapuk putih seperti Trametes sp. telah diketahui mampu mendekolorisasi pewarna azo, heterosiklik dan senyawa reaktif atau polimerik melalui degradasi enzim lignolitik.
