The development of hand sanitizers from a combination of mangrove leaves and patchouli oil has not yet developed in the world and Indonesia, though these two natural ingredients have antibacterial activity as a substitute for alcohol. It is known that many alcohol-based hand sanitizers can cause burning, irritation, dry skin, and cannot be used on wound skin. The purpose of this study was to develop an innovative hand sanitizer in the form of a gel from a combination of mangrove leaves extract and patchouli oil from Aceh. The samples of mangroves (Avicennia) leaves and Patchouli oil were collected from the Kuala Langsa Mangrove Forest and patchouli farmers in South Aceh. Staphylococcous aereus bacteria were obtained from the Laboratory of Universitas Sumatera Utara. This study used a completely randomized design (CRD) with three replications for the gel formulation. The study prepared four formulations namely K (-) as control without mangrove extract and patchouli oil, F-I contained 1g mangrove extract and 10mL patchouli oil, F-II contained 5g mangrove extract and 20mL patchouli oil, and F-III contained 10g mangrove extract and 30mL patchouli oil. Gel hand sanitizer formulations were test for antibacterial active using diffusion method against S. aereus. The data were analyzed using one-way ANOVA. The results of the gel hand sanitizer formulation showed inhibitory effect against S. aereus with the diameter zones of 12.6 mm, 21.33 mm, 19.61 mm and 25 mm for negative control, F-I, F-II, and F-III. The F-III formulation was found as the maximum formula to inhibit the growth of S. aereus.

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%.

The study aims to determine the price fluctuations and their effects on patchouli farm and patchouli oil production in Aceh Province. The Research Method used survey method with an explanatory research as an approach. The location of the study was conducted in Aceh Province, in Aceh Jaya Regency and Aceh Barat Regency. The fluctuations of patchouli oil price have an affect to the motivation of farmers in developing patchouli farming. Farmers in the study location tend to do patchouli farming when the price of patchouli oil is high, instead farmers do not do patchouli farming when the price of patchouli oil decreases. The fluctuations in patchouli oil prices determined by the quality of patchouli oil and market demand have a dominant influence on the development of production and the productivity of patchouli in Aceh. Standardization of patchouli oil quality at the agro-industry level will increase the price of patchouli oil at the farmers level and increase farmers' income. The price of patchouli oil fluctuates depends on Patchouli Alcohol (PA) levels. This is the main reason for traders at the district and provincial levels to reduce prices at the farm level. Aceh Patchouli has oil quality that qualified with basic export standards. But there is still a need for cultivation techniques and better application of refining technology to improve the quality of patchouli oil at the farmer level so that it can increase the price of patchouli oil at the farmer level while simultaneously increasing the income and welfare of farmers. The phenomenon of patchouli oil price fluctuations in high has an important role in the development of patchouli oil agro-industry.

In this study, Oyster (Crassostrea gigas) shell powder which contains calcium carbonate (CaCO3) was converted into calcium oxide (CaO). The Oyster shell powder that had been activated was utilized for the adsorption of the methylene blue (MB) dyeing material, which is one of waste water concerns. Oyster shells were crushed and sieved into 100 mesh sized powder and then calcinated at a temperature of 600℃ and 800℃ both for 4 hours period. To determine the adsorption equilibrium, methylene blue (MB) solution was used with varying concentration from 10 to 50 mg/L in which the adsorbent weighing 3 g was put into a conical flash and shaken until the adsorption equilibrium was reached. As for the adsorption kinetics, 250 mL MB solution was used with initial concentrations of 10, 20 and 30 mg/L, with an adsorbent weight of 3 g and a solution at pH 11 for each concentration. The evaluation of the experimental data from the adsorption process is well explained by the Freundlich equation, with the correlation coefficient value (R2) found to be 0.9999, where the value of the adsorption intensity (n) is close to unity; this shows that the adsorption is multilayer or in other words the adsorption energy is heterogeneous. The kinetics study also shows that pseudo second-order model is the most applicable to the adsorption process. From the pseudo-second-order model, with the correlation coefficient between 0.9984 - 0.9999 can explain that the methylene blue (MB) adsorption process is chemically based sorption or in other words termed as chemisorption.

Space transformation occurs in line with the needs and availability of resources owned by space users. The arrangement and utilization of space is carried out to optimize the function of the space owned and the limited space owned by the space user requires an adjustment in the use of the space owned to achieve business goals as well as the comfort of the living environment. Pante Bidari is a banana sale producing area in Aceh, which is located in East Aceh Regency, where the majority of the people work as small entrepreneurs and workers in the Banana Sale Industry. The process carried out when producing Pisang Sale uses a special room consisting of a storage room, peeling room, sale room and packaging room. This study aims to determine how the transformation of space in a small banana sale house. The method used in this research is a qualitative method. This study found that the spatial transformation that occurred in the small businessman's house of Pisang Sale in Pante Bidari District, East Aceh Regency is one way to optimize the utilization and utilization of space, so that the Pisang Sale production room consists of storage room, stripping room, sale room and packaging room. using residential space as an aspect of activity in residential homes, so that ongoing activities are not disturbed by other activities, residential space in terms of space dimensions there are changes that include addition, reduction and movement of space aimed at adjusting space requirements. Judging from the spatial relationship, there are several spaces that are far from each other and close to each other, so that access to activities carried out can optimize the function of the space.

This study aims to predict the occurrence of erosion in the downstream Krueng Meureubo watershed, West Aceh Regency. Erosion is the loss of topsoil due to rain splash which is analyzed as a factor of rain erosivity, but the occurrence of erosion is not necessarily calculated by the occurrence of rain alone, but many other factors, such as soil erodibility, slope and length of land, land cover and the presence or absence of land conservation efforts. the. The Krueng Meurebo watershed shows a large sediment transport, with an indication that the river is getting shallower caused by sediment deposition at the riverbed, this sediment comes from sediment carried through the process of soil erosion. The method used in analyzing the occurrence of soil erosion in this study is the USLE method and uses a Geographic Information System (GIS). The results obtained are the distribution of erosion rate values in 228 polygons, with the largest erosion rate value occurring in polygon 1 with an erosion rate of 8495.308 tons/ha/year. The smallest erosion rate occurs in polygons 30, 34, 35, 179, and 180, with an erosion rate of 0 meaning that there is no land erosion event, which occurs in organosol and glehumus and regosol soil types, land cover is settlements and water bodies. It is concluded that the occurrence of erosion in a land is very dependent on the type of soil and the type of land cover. It is recommended for land with large erosion events to take serious land conservation actions so that erosion events can be minimized and do not occur continuously which of course can cause the watershed to become critical. Conservation efforts can be carried out in various ways, one of which is by vegetative means using plants that can reduce the rate of soil erosion.
