Abstract

The decline in production prices and land ownership shifts have caused people to choose to convert oil palm plantations into corn plantations. Changes in land cover from plantation crops to annual crops is potentially to reduce the chemical properties of peat. This study aims to identify changes in the chemical properties of peat on land for conversion of oil palm to corn plantations. This research was carried out from May to September 2021. Observations and peat sampling were carried out using the Transect method, perpendicular from the drainage channel based on a distance of 2m, 200m, and 400m from the main canal in maize conversion age < 2 years, (3) maize planting aged conversion 2 years. For each land use, 3 sample points were taken with 2 replications at a depth of 0-20 cm and 20-40 cm. The chemical properties of peatlands that have been converted from oil palm plantations to corn plantations include pH 4.18-4.98, water content 163.76-495.81%, ash content 15.5-72.12%, C-Organic 16.18-49.02%, N-Total 1.25-6.92%, P-Total 5.56-255.87 ppm, P-Available 0.63-157.43 ppm, K-dd 0, 38-1.98 me/100g, Na-dd 3.97-13.84 me/100g, Ca-dd 12.26-23.12 me/100g, Mg-dd 14.66-50.84 me/100g , CEC 63.30-498.16 me/100g, total acidity 570-600 cmol/kg-1. After land conversion, the quality of peatlands increased, especially at the age of conversion <2 years and decreased with increasing age of land conversion.

Abstract

Intensive shrimp culture waste contains high nitrogen, reducing water quality and environmental carrying capacity. Anaerobic ammonium oxidation (anammox) is a potential technology for nitrogen removal. This research aimed to analyze nitrogen removal performance in a filter bioreactor (FtBR). Ammonium and nitrite concentrations of 70-100 mg-N/L were added to sterilized seawater as artificial wastewater and flowed to the reactor with HRT 24-hour. After 120 days of the experiment, the maximum nitrogen removal performance with parameters ACE, NRE, NRR were 82.48%, 72.58%, 0.12 kg-N/m3·d, respectively. The nitrogen stoichiometric ratio NH4+-N:NO2--N:NO3--N was 1:1,40:0,12, which was close to the stoichiometry of anammox process. The anammox process can be a new method for intensive shrimp culture wastewater treatment.

Abstract

PT. PLN (Persero) ULP Langsa city is one part of UP 3 langsa, the LS-05 feeder in section two is the location for placing several office buildings. Continuity stable distribution of electrical energy is one of the most important aspects in the distribution system. Based on these problems, the writer was inspired to consuct research with the aim of testing the reliability of the feeders LS-05 and LL-4 which was installed with LBS manuver motorized at both ends of feeders. The LS-05 feeder with section method SAIFI value is 2.2739 times/ customers/ year and SAIDI Value is 8.41995 hours/ customers/ year. For LL-4 feeder witsh the same method SAIFI value is 2.28905 times/ customers/ year, then using RIA-Section technique combined method, LS-05 feeder have SAIFI value is 2,0219 times/ customers/ year, SAIDI value is 8,3082 hours/ customers/ year, LL-4 feeder have SAIFI value is 2.6574 times/ customers/ year and SAIDI 9.3008 hours/ customers/ year. This value indicates thet these two methods have succeeded in showing a reliability index is in accordance with SPLN due to the addition of LBS motorized.

Abstract

Public facilities can be accessed by everyone, whether they have physical limitations or not.The Al-Hakim Mosque in Padang City is one of the facilities that is a place of worship for Muslims as well as a tourist attraction in West Sumatra.The research was conducted by identifying the inhibiting factors for persons with disabilities when using these facilities, designing these facilities to be easy to use by persons with disabilities (especially wheelchair users), and making a budget plan for making these facilities. Identification of inhibiting factors is done by making checklist to see the various obstacles experienced by wheelchair users and selecting anthropometric variables needed in designing public facilities. The results of this study are in the form of public facility designs that can be used by wheelchair users, the percentage of the suitability of these public facilities after the design is carried out, and the costs required to build these facilities

Abstract

FMEA is a known method in risk management that de-fines the failure that might happen and identifies its hazards on the system; this procedure can be done using the risk priority number “RPN” analysis system. This method is applied on a real repair project “Sheraton Hotel” located in Cairo city near the Nile River where they had to make urgent repairs to avoid failure and collapse of the building. This study concentrated on developing the results and most common failures that might happen in any emergency project by determining the severity, occurrences, and detection to get the overall RPN of each failure. Two methods were used to rank the risks, the first one is the traditional approach which is based on getting one value for the severity, occurrence, and detection. On the other hand, the other method is getting a range of values (3 values) for the severity occurrence, and detection. The results showed that using the traditional form of RPN resulted in three major risks such as ineffective work penalties, complex contractor’s policies, and risks related to contract agreement. On the other hand, the use of a probabilistic analysis showed that the top risks are ineffective work penalties, problems with contract agreement, and unfavorable contract.
