Abstract

The quality of the road depends on the pavement, drainage conditions, and materials. For this reason, it is necessary to make innovations in improving the quality of road pavement, one of which is increasing the material. There are many types of pavements, one of which is porous asphalt pavement. Porous asphalt has many cavities that is easy for water to pass but has a low stability value with high           permeability. This research will utilize Low Density Poly Ethylene (LDPE), as an additive, CPO, and Pen 60/70 in a porous asphalt mixture. The purpose of this study was to determine the characteristics of the porous asphalt mixture by substituting LDPE and CPO for Pen 60/70. The method used in analyzing the characteristics of the porous asphalt mixture refers to the specifications of the Australis Asphalt Pavement Association (AAPA) (2014), with parameters Camtabro Loss (CL), Asphalt Flow Down (AFD), VIM, stability and flow. The gradation used in this study is an open gradation. This research was started from determining the value of Optimum Asphalt Content (KAO), with two variations, namely Variation 1 (1% LDPE, 10% CPO, 89% pen 60/70), variation 2 (5% LDPE, 10% CPO, 85% Pens 60/70). The KAO value of variation 1 is 5.03% and the second variation is 4.75%. After obtaining the KAO value, LDPE and CPO are substituted. The test results for the porous asphalt mixture for CL values were 34.12% and 27.07%, respectively; AFD value of 0.13% and 0.12%; for the VIM value of 14.90% and 19.03%; stability value 603.24 kg and 603.19 kg; and flow values are 5.03 mm and 4.80 mm. In general, the value obtained from the test meets the required requirements. However, the durability value of the mixture did not meet the requirements, namely 60.15% and 48.22%, with the condition >90%.

Abstract

Seiring dengan Meningkatnya permintaan akan bahan baku untuk pembuatan minyak dari kelapa sawit (palm oil) maka pembukaan lahan untuk perkebunan juga semakin besar, akibatnya tutupan lahan menjadi berpengaruh terhadap jumlah air yang diresap oleh tanah karena terjadinya intersepsi.   Intersepsi hujan oleh tanaman adalah proses tertahannya air hujan pada permukaan tanaman yang kemudian diuapkan kembali  ke  atmosfer  atau  diserap  oleh  tanaman  yang  bersangkutan.  Air  hujan  yang  jatuh  diatas tanaman tidak langsung sampai ke permukaan tanah untuk berubah menjadi aliran permukaan (surface run off), tetapi untuk sementara air hujan akan ditampung oleh tajuk, batang dan tanaman. Setelah tempat- tempat tersebut jenuh air, air hujan akan sampai ke permukaan tanah melalui air lolos (throughfall) dan aliran batang (stemflow). Dalam analisis keseimbangan air, intersepsi diperlakukan sebagai kehilangan air (rainfall interception loss) jenis tanaman yang digunakan pada penelitian ini adalah tanaman kelapa sawit. Hal ini disebabkan karena daerah sekitar banyak terdapat perkebunan kelapa sawit. Tujuan studi ini adalah mengetahui  besarnya  intersepsi  kelapa  sawit  dari  berbagai  kelas  umur.  Penelitian  dilakukan  secara langsung di lapangan pada perkebunan kelapa sawit yang terletak di PT. Scofindo Nagan Raya. Untuk mengetahui besarnya nilai intersepsi air hujan dapat dilakukan melalui pendekatan neraca volume yaitu dengan mengukur curah hujan, air lolos dan aliran batang. Hasil penelitian akan didapatkan hubungan antara curah hujan dengan intersepsi hujan berbeda pada tiap kelas umur. Luas proyeksi tajuk  dan curah hujan berpengaruh terhadap intersepsi, air lolos dan aliran batang. Hubungan ini akan membentuk persamaan regresi yang akan digunakan dalam menghitung besarnya intersepsi hujan oleh perkebunan kelapa sawit. Hasil perhitungan didapatkan intersepsi yang terjadi pada pohon kelapa sawit yang 10 tahun adalah sebesar 40,81% mm dan yang 20 tahun adalah 64,04% dari total curah hujan sebesar 225,00 mm. Perhitungan air lolos yang 10 tahun sebesar 56,62 % dan yang 20 tahun sebesar 36,25%. Perhitungan aliran batang yang 10 tahun adalah 7,17% dan yang 20 tahun sebesar 3,12%. Semakin besar curah hujan maka intersepsi semakin besar, dan semakin tua umur kelapa sawit maka intersepsi juga semakin besar.  Kata Kunci: Tanaman Kelapa sawit,  intersepsi, air lolos, aliran batang

Abstract

This study aims to determine the number of biopori infiltration holes (LRB) that can increase water absorption into the soil, so as not to become a puddle. This happens because of land use changes that occurred in the campus field Teuku Umar University, including in the Engineering Faculty Teuku Umar University. Changes in land use and reduced open space on the UTU campus are expected to result in shrinking infiltrated rainwater and causing increased surface run-off. Increasing the flow of this surface can cause the existing drainage channel dimensions are not enough anymore so the water is abundant and there are floods inundation. Therefore, in order to avoid flooding this puddle, it is necessary to enlarge the infiltrated rain water, among others, with “Lubang Resapan Biopori” (LRB). The location of the LRB is done in front of the Faculty of Engineering building located on the UTU campus land, the LRB manufacture is done in 3 locations but one of the locations can not be used because of high runoff and puddles, therefore only 2 locations are made LRB manufacture, 3 cylindrical holes are made by digging in the soil using manual drill tool, 10 cm diameter drill bit and 80-100 cm long, and 100 cm LRB spacing, then organic waste. From the results of data analysis, the number of biopori infiltration holes recommended for the UTU Faculty of Engineering area requires as many as 68 LRB.

Abstract

The value of travel time becomes an important part of profits in the assessment of a transportation project in terms of economic considerations. The time value is usually proportional to per-capita income, which is a fixed ratio to the income level. As for the limitations of the problem in this study is only done on a single market contained in the city of Meulaboh Business Market located at Jalan Daud Dariyah II Meulaboh City for the survey by way of filing questionnaires to kiosk owners and employees stalls Market Business as respondents , As well as compiling survey results into planned formats. The questionnaire data is inputted and then recapitulated to be analyzed by Kolmogorov-Sminnov Normality test method to ensure valid / normal data, and analysis ofspearman's rho and kendall's tau test methods in SPSS (Statistical Product and Service Solution) software. Based on the analysis of time value of go-and-go time of the seller, for the kiosk owner the time value goes 567,41 Rp / minute and the return time value is 108,18 Rp / minute. Sedangka for employees kiosk 691,68 Rp / minute (go) and 108,00 Rp / minute (go home). Furthermore, the results of the normality test stages by kolmogorov-smirnov with SPSS (Statistical Product andService Solution) method show that the output of the travel costs of owners and employees of kiosks (go-home), and the value of time owners and employees kiosk (go-go ) Value significance correction (Sig) <0.05, means that data is not normally distributed. Implementation on the data normality test (kolmogorov-smirnov) if the significance is below 0.05, means that the data has a significant difference with the normal raw data. Furthermore, non-parametric statistic is used with spearman's rho and kendall's tau, to know the relationship between travel cost and travel time value. The result of spearman's rho correlation shows positive number (+) on correlation coefficien, as well as correlation coefficien's correlation or tau indicates positive number (+) on correlation coefficien, meaning the greater the travel cost the greater the travel time.

Abstract

Sabang city is one of the major tourist destinations in Aceh province and needs to ensure its area is in a low-risk flood inundation zone. However Sabang city has not had a good and comprehensive drainage system yet and often experienced flood. Its Sabang's topographical feature which consists of mountains, hills, and plains, has caused the drainage system of Sabang to be unique and special. According to Sabang Spatial Plan Year 2012 to 2017, Sabang should improve the function of its drainage infrastructures immediately. Nonetheless, due to budget constraints it is necessary to determine the handling priority of drainage system of Sabang city during the next 20 years. Determination of handling priority of Sabang’s drainage system is based on the physical, demographic, and environmental aspect and is in accordance with survey results and analysis of secondary data. The selection of priority of service areas is performed by weighted average method. Based on the analysis of the three factors described above, it can be seen that the handling priority of subwatershed for short-term is in subwatershed Anoi Itam, subwatershed Krueng Balohan and sub- watershed Pria Laot; medium-term is in subwatershed Keunekai, subwatershed Ceunohot, subwatershed Aneuk laot, subwatershed Paya Seunara; and long-term is in subwatershed Ceuhum, subwatershed Ujung Bau, subwatershed Gua Sarang, subwatershed Teupin Kareung and subwatershed Iboih. Keywords : Priority, drainage system, weighting average, Sabang city
