/in /by

This study aimed at evaluating the pH, nutrient content and nutrient loss of silage that were made of different ages Red Napier grass (Pennisetum purpureum cv. Red) and the addition of Lactobacillus plantarum. The experiment employed Nested Completely Randomized Factorial Design consisted 2 treatment factors i.e. the grass of 50, 60, 70 and 80 harvested days after planting as first factor and the addition of three levels of Lactobacillus plantarum i.e. 0, 103 and 106 cfu/g as second factor. Each factor combination was replicated 3 times. Collected data were subjected to analysis of variance followed by Duncan’s Multiple Range Test (DMRT). It was found that harvest ages did not affect pH (p>0.05) but level of L plantarum significantly (p<0.05) affect silage pH measured at day 7 and highly significantly (p<0.01) affect pH at day 14, and 21. L plantarum significantly (p<0.05) affect DM loss, and highly significant (P<0,01) affect OM loss, while the different harvesting ages gave highly significant (P<0,01) affect CP loss.The higher level of L. plantarum can increase the DM, CP and decrease levels of CF, NDF and ADF. It can be concluded that interaction between Red Napier grass of 50 harvested days after planting and addition of L. plantarum 106 cfu/g produced the good quality silage based on the relatively low weight loss of DM, OM and CP.

Managing Work Requests to Improve Level of Building Maintenance Services

/in /by

Building and Facilities Maintenance Section is one of the sections in Infrastructure Facilities Department in PT.ABC that deals with the maintenance and operation of building facilities in non-PIT areas. PT. Sumber Karya Utama is the contractor appointed to carry out the building maintenance contracts. In contrast to the KPI of 90% for Work Request completion, the total incoming WR addressed to the section has a completion rate of 65% every month.

Delays in completing Work Request work are due to the fact that there has not been a structured work schedule made, the planner have difficulty making Work Order work plans is because the WR descriptions are random and the work locations are spread out. The Building Maintenance Section developed a Standard Operation Procedure (SOP) for writing Work Request to standardize writing descriptions to the main job, so the planner could assess, identify and making categorized of the type of work item into work group items easily.

To establish a work schedule, prioritize work group items using the SMART method. The data used are list of work items, work groups, alternatives, criteria, and weighting. The sequence of work schedules runs effectively by implementing a division into 5 work areas so that work schedules are made per work area.

By implementing work priority references and dividing the area into 5 work areas, WO work can be completed on time, more fairly distributed, efficiently completed, and acceptable to all parties involved, thereby improving the performance and quality of services provided to customers, as well as ensuring that building maintenance runs smoothly and continues to function properly.

Microbes in Plastic Degradation

/in /by

Due to increasing production of plastic and its piling up is a critical concern hence ways to degrade the plastic needs to be sought out. Microplastics (MPs) of the size of micron or less have been found everywhere, even in human blood, highlighting the adversity of the situation. Natural and microbial degradation mechanisms of MPs, focusing on polyethylene (PE) and polyethylene terephthalate (PET) have been explored by the study. Natural degradation is hindered by stability and hydrophobic properties of the polymers. Despite recycling efforts, a significant portion of PET waste ends up in landfills and the environment, posing threats to ecosystems and organisms. MPs are ingested by aquatic organisms, serve as substrates for unwanted microbes, and act as vectors for toxic chemicals. Atmospheric and aquatic fluxes contribute to the transport of MPs from production sources to marine environments. Microorganisms like bacteria, can degrade plastic polymers. Bacterial cultures are found to be effective in degrading MPs through extracellular and intracellular enzyme systems. Bacterial degradation of PE and PET has been demonstrated in laboratory conditions, with varying removal efficiencies and degradation durations. Abiotic factors like oxygen and light help in the PE degradation, while hydrolase enzymes are involved in PET degradation. For effective plastic management, a cyclic bioeconomy based method is necessary, which involves reconsideration of the entire value chain of plastic. Future-proofing plastic waste management requires delinking plastic production from fossil-based raw materials and energy sources. Additionally, addressing agricultural and food waste losses can contribute to reducing the carbon footprint associated with plastic production. Overall, understanding the microbial degradation of plastics offers promising avenues for combating plastic pollution and achieving a more sustainable plastic waste management system.

Effectiveness of Various Media in Propagating Local Isolates of Metarhizium anisopliae

/in /by

Entomopathogenic fungi are a type of biological agent used for this purpose. Previous research by the author demonstrated that local isolates of the entomopathogenic fungus Metarhizium anisopliae, when supplemented with insect flour, could enhance conidia production, viability, and virulence. This makes the isolate suitable for development as a bioinsecticide. For the growth of entomopathogenic fungi as biological agents, a sufficient supply of high-quality inoculum and efficient production methods are essential. Currently, solid media such as rice and maize are used for propagation, which is costly. Therefore, there is a need for new alternative media that are economically viable, nutrient-rich, effective, easy to obtain, and abundant in raw materials. Additionally, the media must support the growth and proliferation of entomopathogenic fungi. The objective of this study is to identify the most effective media for the propagation of M. anisopliae. The study employed a completely randomized design (CRD) with 8 treatments and 4 replications, resulting in 32 experimental units. The treatments included various media: rice bran, tofu leftovers, broken maize, sweet potatoes, cassava, husks, and green beans. Data were processed using variance testing, followed by the BNT test at a 5% significance level. The study’s findings indicate that the rice bran medium had the highest growth percentage of M. anisopliae, reaching 100%. It also proved to be the best medium in terms of incubation time, fungal colony diameter, and conidia/mg.
