ABSTRAKSlag nikel (FeNi4) adalah jenis terbaru dengan ukuran butiran mendekati pasir (lolos No. 8). Jumlah buangan slag nikel telah mencapai 1 juta ton pada tahun 2018, sehingga berbahaya bagi lingkungan jika tidak dimanfaatkan secara luas. Disisi lain kebutuhan agregat halus campuran aspal jenis Hot Rolled Sheet (HRS-WC) sangat tinggi. Penelitian ini bertujuan untuk mengetahui potensi pemanfaatan slag nikel FeNi4 sebagai agregat pada campuran aspal jenis HRS.Slag nikel (FeNi4) diperoleh dari PT. Antam Pomalaa. Penelitian dirancang dengan tiga variasi penggunaan slag terhadap agregat halus standar yaitu Variasi 1 (0/100%); Variasi 2 (50/50%); dan Variasi 3 (100/0%). Penyetaraan berat jenis dilakukan untuk menghitung jumlah slag yang digunakan. Jumlah sampel sebanyak 45 sampel dan diuji menggunakan alat Marshall Test. Spesifikasi yang digunakan dalam penelitian mengacu pada Bina Marga 2010.Hasil penelitian menunjukkan bahwa pada benda uji Variasi 2 (50/50%) masih diperoleh kadar aspal optimum sebesar 6,319%, hampir sama dengan kadar aspal optimum benda uji kontrol sebesar 6,331%, namun dengan range kadar aspal yang lebih sempit. Temuan ini menunjukkan bahwa slag nikel FeNi4 sangat berpotensi digunakan dalam campuran HRS-WC namun dibatasi sampai 50%. Penelitian lanjutan dapat lakukan untuk mengetahui karakteristik campuran HRS-WC pada penggunaan slag nikel FeNi4 dibawah 50%. Kata Kunci : Slag, Antam, Nikel, Aspal, AgregatABSTRACTNickel slag (FeNi4) is the latest type that was close to sand material (pass No.8). The amount of nickel slag discharges reached 1 million tons in 2018, making it dangerous for the environment if not widely used. On the other hand, the need for fine aggregate asphalt mix type Hot Rolled Sheet (HRS) is very high. This study aims to determine the potential use of FeNi4 nickel slag as fine aggregate in the HRS mixture.Nickel slag (FeNi4) obtained from PT. Antam Pomalaa. The study was designed with three variations of the use of slag against standard fine aggregates, namely Variation 1 (0/100%); Variation 2 (50/50%); and Variation 3 (100/0%). Equal density is done to calculate the number of slags used. The total sample is 45 samples and tested using Marshall Test. The specifications used in the study refer to the 2010 Bina Marga.The results showed that Variation 2 (50/50%) of the specimens were still obtained optimum asphalt content of 6.319%, almost the same as the optimum asphalt content of control specimens of 6.331%, but with a narrower range of asphalt content. These findings indicate that FeNi4 nickel slag is very potentially used in HRS-WC mixtures but is limited to 50%. Further research can be done to determine the characteristics of the HRS-WC mixture on the use of FeNi4 nickel slag below 50%. Keywords : Slag, Antam, Nickel, Asphalt, Aggregate

Abstract Ageing is one of the small parts that causes damages and decreases to the flexible pavement construction strength especially the asphalt concrete mixture. Adding the asphalt content in the mixture is one of several ways to anticipate the ageing process in the asphalt mixture (Asphalt Institute, 2001).This research was performed by manufacturing the STOA samples (Brown dan Scholz,2000). Variation of adding asphalt content were 0.25%, 0.50% and 1.00% to the requirement from the optimum asphalt content (5.90%). The specification of asphaltic concrete mixture based on Kimpraswil 2002. The examination of strenght of the mixture was conducted by using the Marshall, Immersion and Cantabro test method.The results of this research indicated that base on the Marshall characteristics obtained the maximum value of the addition of aspahalt was at 0.50%. The condition was indicated decreasing strenght, but the stability value of 1371.82 kg, flow value of 3.50 mm and MQ value of 391.70 kg/mm were satisfied to the requirement. The Immersion Index value to the Immersion test of 48 hour by the addition of asphalt at 0.50% obtained 90.38%. The percentage loss of mass value after 300 times of rotation showed that the addition of asphalt at 0.50% obtained 4.64%. Keywords: Ageing bitumen, Asphaltic Concrete, Marshall tes.

Aggregate materials used in asphalt mixture is based on assumption which is materials came from the same sources, quality, and heaving the same specific gravity or almost same. There for the used of alternative filler in HRS mixture need to examinated to find filler content that produce the optimum asphalt content as reference of mix performance. This research conducted to HRS-Wearing Course type. Kind of alternative fillers in this research are hydrated lime filler and slag nickel filler. Material testing based on AASHTO/ASTM standard while filler content variation of hydrated lime filler and slag nickel filler are 1%; 3%; 5%; 7% and 9%. At each variation of comparison filler was made sample by asphalt content : 6,0%; 6,5%; 7,0%; 7,5% and 8,0%. Each specimen conducted the examination through the Marshall Test apparatus. Determination of the optimum asphalt content based on the narrow range method, conformed to the 2002 specifications of Kimpraswil Department. Result researched found that using filler content of 7% of hydrated lime can produce the optimum asphalt content (7.63%) and using filler content of 1% of slag nickel can produce the optimum asphalt content (6,75%). Stability value compare to dust filler is higher (1910.41 kg) than hydrated lime (1489.20 kg) and slag nickel filler (1525.40 kg) The value that is obtained from both fillers substitution is still fulfill the 2002 specifications of Kimpraswil Department for HRS-WC that is stability value recommended more than 800 kg.

Lalouesamba Village is one of the youngest villages in the South Konawe Regency, with a non-coastal slope topography of 82 meters above sea level and an area of about 4.1 km2. The majority are farming/gardening, coolies, and construction workers are the main occupations. Potential water resources include rivers with a width of 3-5 meters around the village. Each 1 artesian spot, boiling water spot, murky water borehole, and 5 units of wells with a depth of 15 meters. The problem with this village partner is that there is still a lack of access to clean water, so the solution offered to lift/pump the potential for river flow is to use a hydraulic ram pump without electricity & fuel. Therefore, this community service activity aims to provide an understanding of hydraulic ram pump knowledge and open insight into the potential for welfare due to the pump. The results of the transfer of knowledge of hydraulic ram pumps show a good indication with the achievement of the main material up to 80% based on the results of the feedback questionnaire and it can be stated that the villagers of Lalouesamba are ready to advance to the next stage, namely practical training on assembling/making hydraulic ram pumps. Requests for additional discussion from residents and village heads are evidence of the enthusiastic response, which is a sign of the opening of insight into the potential of hydram pumps for the welfare of villagers after receiving enlightenment about hydram knowledge

Abstract The results of this research show that the value of the stability of the third draft of specification variation Latasir value obtained above 200 kg. The value for the flow of the third draft variation no one specification with a value between 2-3 mm. The results obtained for the Marshall value Quotient (MQ) in variation II for different types of asphalt levels of specifications. Latasir. For the value of the percentage of The Aggregat Minral Voide (VMA) for the third draft the variation vercentage value obtained above 20%, so that the third draft of the variations can meet the specification. Retrieved value Void Filled With Asphalt (VFWA) on the draft variation II with asphalt levels 10%, 11% and 12% by value of VFWA percentage above 75%. While the value of the Void In The Mix (VIM) obtained on the draft Variation I in asphalt levels 12% with the highest percentage of 5,39%, thus entered in the specification of the latasir with the value of the percentage of VIM between 3-6%.
