Abstract

Inventory management is an essential aspect of supporting good production planning in company business activities. The implementation of inventory management in the company is a primary need. If there is a problem in the supply of raw materials, all the company's operational activities will be disrupted. Inventories in manufacturing usually consist of raw materials, semi-finished goods, and finished goods or final products. Inventories of arm rear brake materials for the production process often experience shortages due to immature controls. This study aims to determine the inventory control of rear arm brake raw materials using the Economy Order Quantity (EOQ) method at PT. Ciptaunggul Karya Abadi. Based on the discussion results, it was found that ordering raw materials was carried out two times a year with a total order of 621 pieces with 86 pieces of safety stock and will be ordered again when raw materials collected 21 pieces. Total Inventory Cost (TIC), which was initially Rp110.264.235,00, can be saved to Rp70.598.399,00 so that the total savings that occur are Rp39.674.899,00 which is equal to 33.26%.

Abstract

Currently, technological development is very much needed as information systems are increasingly stringent and require the readiness of an organization. Government agencies very much manage and serve the community so that the role of government is very influential to serve the community for example for the management of correspondence. The use of the existing mail information system does not meet the standards of technological development, because the existing data processing system is still done manually using Microsoft Word. The problem that is often faced when making a letter by hand is that people who make a letter have to wait a long time, because officers must input data manually. The purpose of this research is to create a system to serve the public in making letters, so that officers can provide services quickly and accurately. The results of this study are the information system that was designed to be able to provide convenience and update the administration of the letter agenda that previously was still using the manual method.

Abstract

Agricultural waste such as rice straw, rice husk and rice husk ash have not been utilized properly. This waste of agricultural produce can actually be used as an alternative to bionanofiller because it contains an excellent source of silica. The silica content contained in the rice waste when combined with the polymer matrix can produce composites having high thermal and mechanical properties. Characterization of bionanofiller from this rice waste is done by SEM, XRF, FTIR, XRD and particle density. The result of SEM analysis from this rice waste is feasible to be used as filler because it has size 1 μm. Likewise with the results of XRF analysis that rice waste contains a high enough silica component that is 80.6255% - 89.83%. FTIR test results also show that bionanoparticles from rice waste have the same content of silica. In the XRD analysis the best selective gain of rice waste is found in rice husk ash which is characteristic of amorp silica at a range of 2ϴ = 22. The largest density analysis of paddy waste was found in rice husk 0.0419 gr / cm , followed by rice straw by of 0.0417 gr / cm 3 and rice hulk ash 0.0407 g / cm 3

Abstract

Land conversion activities cause changes in the area of vegetation and carbon storage in the air. These changes can lead to emissions (reduction of carbon stocks) or sequestration (addition of carbon stocks). This study aims to calculate stored carbon in the Padang watershed in 2009 and 2019 and to determine the dynamics of emissions and carbon sequestration due to land conversion in the Padang watershed, North Sumatra Province from 2009 to 2019. The method used in this research is spatial data processing using software Arc Gis. Processing, interpretation and classification of land cover are obtained from land cover data for 2009 and 2019 from the Ministry of Environment and Forestry. Furthermore, the analysis of emissions and carbon sequestration in the Padang watershed was carried out using the REDD Abacus SP software. The results showed that the total carbon stored in 2009 was 5,168,464.09 tons. Meanwhile, the total carbon stored in 2019 was 5,150,784.81 tons. This means that there is a decrease or carbon emission during the 2009-2019 period of 17,679.28 tons. The total net emissions and sequestration that occurred in the Padang watershed due to changes in land use from 2009 - 2019 were 22,851,751.43 tonnes CO2-eq / year and  3,100,199.00 tonnes CO2-eq / year, respectively. Efforts to reduce emissions include planting and developing forests and community-based forest management.

Abstract

Indonesia as the largest producer of palm oil, produces huge palm oil wastewater. The wastewater produces biogas which contributes to global warming, and the utilization of the biogas reduces GHG emissions of methane gas. By increasing the concentration of methane gas in the biogas, and increasing the gas pressure of biomethane, so-called bioCNG (Compressed Natural Gas), the gas utilization easier in the transportation and the energy content of the gas increases. In this paper, an assessment of the economics of bioCNG production facility in the Palm Oil Mill (POM) with a capacity of 60 tons/hour was conducted. The investment cost is estimated based on the biogas flow rate produced from an aerobic digester in the POM. By using a covered lagoon technology for anaerobic digester, and technology of membrane for gas purification, and based on the natural gas trading regulations, the selling price of bioCNG is determined by 10.27 USD/MMBTU with an IRR of 12%. This price can compete with the prices of other fossil fuels. However, the support from government regulations are still needed to utilize bioCNG as a new renewable fuel that can contribute to national energy security, GHG reduction, and achievement of the mix energy target.

Abstract

The lack of domestic wastewater management services in the Cibabat River Basin has resulted in the Cibabat River being a place to collect domestic wastewater. This of course can reduce water quality  as well as reduce the function of the river itself.  The Cibabat river is known to be a sub-watershed of the Citarum River with a surface   area of  1,855 km2. Activities in the Cibabat watershed  contribute  to the pollution load that  causes the water quality of the Cibabat River to decline, which of course has an impact on the decrease  in the quality of the river and increase  in the polluting  load that the river will receive. The research method uses the calculation of the pollutant  load based on Permen LH 115/2003. The data used are  secondary data from DLH Cimahi City, which  conducted a water quality analysis at three points during  three different seasons in 2019. One of the steps to overcome and control the pollution that occurs is to determine the actual pollutant load so that it can easily determine the application of effective technology  for controlling river water pollution  in the Cibabat River at theCimahi City.
