Physical and mechanical properties of asphalt have been improved by adding of few-layers graphene (FLG). FLG was obtained from a simple, low-cost and environmentally friendly liquid shear exfoliation method using a kitchen blender. The melted asphalt at temperature of 150oC was mixed with FLG at various concentrations (10 mg/ml, 20 mg/ml and 30 mg/ml) and contents (0 wt%, 3 wt%, 6 wt%, and 9 wt%) by weight of asphalt. The homogenized mixture was taken for penetration and softening point tests, while the mixing with aggregates was carried out for Marshall stability and asphalt concrete flow tests. The characteristics of void in mixture (VIM), void filled with asphalt (VFA), and void in mineral aggregate (VMA) were also investigated. The penetration values decreased (or the asphalt hardness increased) linearly with increasing of FLG concentration and FLG content. The softening point of asphalt increased as the increasing of FLG concentration and FLG content in asphalt with the average softening point increase of about 5%. The Marshall stability and asphalt concrete flow increased with increasing of FLG concentrations and FLG content. However, the addition of FLG did not affect the VIM, VFA or VMA values. Overall, the addition of FLG improves the physical and mechanical properties of asphalt and has promising prospects due to low-cost and eco-friendly nature of FLG.

The method used in this research is quantitative research. The population in this study were all students of Sunan Ampel Jombang, according to the caregivers, which amounted to 150 students, while the sample in this study was 101 students. Data collection techniques used in this study are observation, interviews, questionnaires and documentation. The data analysis used in this research is product moment correlation analysis. Based on the results of the study showed that the Spiritual Intelligence of the Sunan Ampel Islamic boarding school students obtained 41.9 results. Based on this number, it can be concluded that the average score of the Spiritual Intelligence of the Santri is between 40-50 with very high criteria, while the obedience of the students in carrying out the rules is 41.0. Based on this number, it can be concluded that the average student awareness in carrying out the rules is between 30-40 with high criteria. Based on the calculation of the product moment correlation that has been done, it can be seen that rxy or rcount with a total of 0.640 is greater than rtable, so Ha is accepted, that is, there is a relationship between the level of spiritual intelligence and the obedience of students in carrying out the regulations of the Sunan Ampel Islamic Boarding School Jombang.

Mint plants are generally grown on a small scale and are found growing wild in mountainous areas and in damp and watery places. This plant is able to adapt to tropical climates so that it can be cultivated. The purpose of this article is to provide counseling on how to cultivate mint leaves and use them as a fresh and healthy health drink at SMP IT Khazanah Boarding School. The method used is to provide counseling and practice it directly, how to cultivate and utilize mint plants as a fresh drink. Planting mint can be done by cutting existing plants. The trick is to cut the stalk about 1 cm above the branching. Then, remove some of the leaves on the stalks and submerge them in a container. Mint leaves have a distinctive spicy taste, fresh scent and have various benefits for the body, such as refreshing breathing, calming digestion, boosting immunity, and others. As for how to use it as a fresh drink for health which is combined with several ingredients such as Mint leaves, Lemons or Lime that have been cleaned, Honey or Sugar, and Hot Water. Then the lemons are cut into thin strips, then honey is added and the boiling hot water is poured into the container, then the mint leaves are dipped, and let stand for a moment so that the mint and lemon flavors are stronger then they can be served and drunk in warm conditions. The results obtained were that the teachers and students were very enthusiastic about participating in the community service activities carried out by the Riau University lecturer team from start to finish and almost all participants were excited to try planting, making drinks and enjoying fresh drinks from mint leaves.

The Soil and Water Assessment Tool (SWAT) model which is integrated with the Geographic Information System (GIS) can provide an overview or prediction of the influence of land management on the hydrology of the Micro Sei Tanduk watershed in accordance with the interests of evaluating and monitoring watershed management activities. The purpose of this study was to analyze the management of the Sei Tanduk Micro watershed based on land use patterns, as a basis for determining the best recommendations for planning and evaluating the Indragiri Rokan Watershed Management Project Activities for Fiscal Year 2003 by compiling a Master Plan for the Micro Sei Tanduk Watershed Master Plan Rumbio Village, Kampar Regency. The research method is to process primary and secondary data using a SWAT model that is integrated with GIS in analyzing hydrological characteristics in land use scenarios in the management of the Micro Sei Tanduk watershed, as a basis for providing recommendations. The best recommendation from the evaluation and analysis of the Micro Sei Tanduk watershed management based on land use patterns is scenario 2 in the form of applying agroforestry on mixed dry land agriculture with the insertion of forestry trees based on community participation in the Micro Sei Tanduk watershed, Rubio Village, Kampar District, Kampar Regency.

ABSTRACTon-structural concrete consists of sand, coarse aggregate (palm shell / crushed stone), portland cement adhesive materials and water. Palm shells are treated as coarse aggregate in the concrete mix non-structural as palm shells loud enough to rupture the field are pretty much expected to be able to replace the coarse aggregate properties. Productivity palm shells are quite large in Riau Province with the extent of oil palm plantations.Primary data collection that consists of data analysis grain palm shells, sand grains of the data analysis, the data characteristics and non-structural concrete compressive strength. The materials used are cement Padang kind of PCC, sand from the lake bingkuang Kampar and palm shells of PTPN V Raja Beach Kampar.
