Abstract

Composting is a form of decomposing organic matter with the help of organisms for bioconversion. The composting process requires several requirements to produce good quality compost, namely water content, pH and nutrient availability which is reflected in the C / N ratio. One type of insect larvae that can be used as an element of organism is the Black Soldier Fly (BSF) insect. The effort to recycle organic waste involving Black Soldier Fly (BSF) insect larvae is a new paradigm in the management of organic waste as decomposers or decomposers of organic waste. The result of the conversion of organic waste into solid compost fertilizer has a moisture content value that exceeds quality standards, C-organic value and C / N ratio which is below the quality standard, has a basic pH, and macro nutrients (N + P2O5 + K2O) located in the Permentan quality standard No. 261 / KPTS / SR.30 / M /4/2019, while for liquid compost fertilizer the value of C-organic and macro nutrients (N + P2O5 + K2O) is in Permentan quality standard No.261 / KPTS / SR.30 / M / 4/2019.

Abstract

Benzene, Toluene and Xylene (BTX) compounds are compounds that have colorless and flammable characteristics, have a sweet odor with a low toxicity level, and are not soluble in water. This compound is often used as a solvent, extractor and as a chemical intermediary. The testing of BTX parameters in the working environment refers to the National Institute of Occupational Safety and Health (NIOSH) method number 1501. The method must be modified or developed in terms of equipment and instruments, due to looking at the condition of the materials and equipment in PT UP, i.e. using different columns, capillary columns, fused silica, 30m x 0.32-mm ID; 1-μm film 100% PEG becomes a Rtx-5MS column, and measurements using a FID detector become a Mass Spectrometer detector. And the solvent used is Carbon Disulfiida (CS2) to Methanol for gas chromatography. CS2 solvents are carcinogenic in the body so that they are harmful to human health. Besides being harmful to health, the waste produced by CS2 causes damage to the ozone layer on the earth's surface so that it can trigger global warming which will make the earth feel hot. In addition, CS2 solvents in Indonesia have begun to be reduced in production and will be illegal inthe future. Therefore, this method needs to be validated before doing a routine analysis so that the data obtained is valid.

Abstract

The purpose of the study was to analyze the risk of work accidents using the FMEA (Failure Mode and Effect Analysis) method at the Bukit Tua ORF project at PT Raga Perkasa Ekaguna, Madura in 2018. The study used a descriptive method with a qualitative approach. The results showed the ranking of severity scale, failure mode with the highest scale with a value of 10 is the object falling on the lifting by crane activity and on the type of accident the collapsing excavation wall fell upon workers on the activity. The smallest severity scale of failure mode is exposed to UV rays for a long time with a scale of 2. The occurance scale, the highest cause of failure mode is a sling or broken steel rope with a value of 7 in lifting by crane activities. As for the occurance scale, the lowest cause of failure mode is the distance between workers too close to the value of 1 on the activities of road, drainage, foundation. The highest scale of detection, cause of failure mode is to ensure the condition of the equipment before work begins with a value of 7 in lifting by crane activities. The lowest detection scale is the distance between workers too close to the value 1. The highest RPN calculation result is the lifting by crane activity that causes the object to fall, with an RPN value of 490. Improvement of Fishbone diagram results, to humans or workers by providing training on hazards caused by lifting by crane activities, the chief coordinator or supervisor is expected to always supervise the performance of his subordinates. Machines, by conducting routine checks on each of the tools used in crane lifting activities. Regular company checks can schedule regular repairs to these tools. The method, by making SOPs and lifting plans correctly that is by using the right calculations, can be done by coming directly to the work area and doing simulations using cranes that will be used as well as seeing the material to be raised in this activity. So that the data obtained to make SOP and or lifting plan are accurate so that it gets a precise calculation. Environment, by installing barriers or prohibited signs to pass, so that no unauthorized person enters the area during the appointment. Check the condition of the soil so that it remains stable in the lifting area by the crane.
