Abstract

This study was aimed to determine the feasibility level of the final disposal site (TPA) based on physical aspects in the Oransbari District according to SNI 19-3241-1994 and SNI 03-3241-1994. The method used is descriptive with field observation techniques. Measurement starts from the groundwater level using geoelectric mapping: Types of rock and distance to faults based on geological maps: slope, distance to rivers, distance to shoreline, and distance to airports based on topographic maps; rainfall data from BMKG; flooded and protected areas. Based on the results of the analysis of 10 physical parameters with the accumulated assessment (scoring) that has been done that the candidate for the location of the Final Disposal Site (TPA) is in the second interval class, with a score of 161, so that the feasibility value of the landfill location is included in the interval class 129 – 224. and categorized as “Required Enough”..

Abstract

Estimation of the presence and depth of groundwater is carried out using the Geoelectrical resistivity method with a dipole-dipole configuration consisting of 5 measuring lines. The results of the research are as follows on track 1 there is an aquifer with a depth of about 13-20 m and track 2 has an aquifer with a depth of about 25-50 m where both of these lines have an aquifer that flows to the Unipa Water Pump. Track 3 is interpreted to a depth of 50 m and the results cannot show the presence of groundwater with the lowest resistivity (????) value reaching 140 m. On track 4, the resistivity value (????) is 40 m and it is suspected that there is an aquifer with an estimated depth of >50 m. Track 4 has a stretch of 160 m so that geoelectrical data are interpreted to a depth of 50 m. Track 5 can be interpreted to a depth of 63 m and the interpretation results cannot indicate the presence of aquifers or groundwater.

Abstract

This research aims to produce a windmill blade design simulation using Airfoil NACA series 4412, 4415, 23012, 23015 and to determine the best type of windmill blade design based on the amount of power generated by the wind speed. The blade design was made using the Qblade v0.91b program based on the NACA 4412, 4415, 23012, and 23015 airfoils with taper and taperless types. Blade design begins with determining blade geometry and continues with blade design performance testing. Wind speed in Manokwari is classified based on the limit of the effective wind occurring in a day, which is 9 hours. The results showed that NACA 4412 and NACA 4415 were better than NACA 23012 and NACA 23015 with the efficiency of each blade reaching 49%. The NACA 4412 series taper produces an average total power per month of 168.38 KW and taperless of 196.93 KW from the average number of occurrences of potential wind speed of 9.35 m/s of 26 days. The NACA 4415 taper blade produces 164.8 KW of power while the taperless blade is 192.73 KW for the same average number of wind potentials. Based on the amount of power generated, the taperless type in the 4412 series is the best blade for wind speed in Manokwari.
