This study aimed to examine the laboratory-based preparation of chitosan-gelatin bio-composite with the addition of glycerol as an additive to improve its quality which could be further applied for primary wound dressing. The method consisted of three stages; the first was the preparation of raw materials, the second was the preparation of the bio-composites, and the last was the characterization. In this study,chitosan 90.2% DD and gelatine (dissolved in 1% acetic acid) were blended at volume ratios v/v (30:70), and glycerol was added into blended at five different volume 20, 25, 30, 35, 40, 45 (mL) respectively. The biocomposites is then shaped in a glass mold, allowed to at room temperature for 24 hours, and dried in oven at 50oC for 48 hours. The chitosan-gelatin-glycerol bio-composites was smooth, flexible, transparent thin sheet and non-porous. The optimum thickness (4.01 mm) was obtained from a bio-composite with chitosan-gelatin-glycerol ratio of 30:70:45. The same composition rasio was found to have the liquid absorbance reaching 140.34%. The bio-composite with a chitosan-gelatin-glycerol ratio of 30:70:45 also had the highest swelling ability in saline (168.06%). The functional group analysis using Fourier Transform Infrared (FT-IR) spectroscopy revealed the possession of hydroxyl (O-H) and carbonyl (C-O) functional groups suggesting its good biodegradability and environmentally friendly properties. Taken altogether, the results imply the wound dressing bio-composite is hydrophilic. Based on the results of characteristic testing, it is shown that the chitosan-gelatin-glycerol biocomposite has the potential to be applied as a primary wound dressing, which is ideal for wound healing and protection.

Bioethanol characteristics can be used as an alternative fuel to spark-ignition (SI) engines to reduce emissions. This experiment evaluates the production of emissions for SI engines using hydrogen enrichment in the gasoline-bioethanol fuel blends. The fraction of bioethanol fuel blend was added to the gasoline fuel of 10% by volume and hydrogen fuel produced by the electrolysis process with a dry cell electrolyzer. The NaOH was used as an electrolyte which is dissolved in water of 5% by a mass fraction. The test is conducted using a single-cylinder 155cc gasoline engine with sensors and an interface connected to a computer to control loading and record all sensor variables in real-time. Hydrogen produced from the electrolysis reactor is injected through the intake manifold using two injectors, hydrogen injected simultaneously at a specific time with a gasoline-bioethanol fuel. The test was conducted with variations of engine speeds. The emission product of ethanol--H2 (BE10+H2) was an excellent candidate as a new alternative of fuel solution in the future. The engasolinerichment of hydrogen increased the flame speed and generated a stable combustion reaction. The hydrogen enrichment produced CO2 emission due to the unavailability of carbon content in hydrogen fuel. As a result, the C/H ratio is lower than for mixed fuels.

Environmentally friendly plastics can be degraded biologically in an anaerobic environment. This plastic is synthesized from starch such as sago starch which is available in abundance. In the form of bioplastics, its mechanical properties are still not compared to conventional plastics derived from crude oil, so its application is limited. The incorporation of filler material increases its mechanical properties, one of the selected fillers is hemp fiber as used in this study. Thermoplastic starch from sago with flax fiber as a filler and the addition of Polypropylene to improve mechanical properties with a certain composition to maintain its natural biodegradability. The mechanical properties analyzed were tensile strength, elongation and modulus of elasticity. Water absorption tests were also carried out to observe the water resistance properties. The results of the tensile strength test showed that the best tensile strength value of 9.32 Mpa was obtained at the addition of 35% fiber with a TPS: PP ratio of 1:1.5. The same conditions were obtained for the percent elongation with the results of 10.16% and the modulus of elasticity was 91.73 Mpa. Water absorption showed that 55% filler gave the lowest water Â Â Â Â absorption, namely 4.41% at a ratio of TPS: PP 1:0.5. The addition of fiber filler into the bio-composite affects the tensile strength, Â Â Â elongation and modulus of elasticity, the higher the volume of filler entering the bio-composite, the lower the value of tensile strength, elongation and modulus of elasticity, or vice versa. The ratio of addition of polypropylene matrix is also influential, the higher the ratio contributes to the tensile strength, elongation and higher modulus of elasticity. High water absorption capacity will reduce the performance of biocomposite, so the lower the water absorption ability, the better the quality of the biocomposite product and the wider its application

The rapid progress in the field of information technology, especially the internet, has given birth to a lot of information. The ease of publishing an article on a website causes an explosion of news pages which will certainly confuse readers. The diversity and the increasing number of news articles make it increasingly difficult for internet users to find news and large piles of news data on online newspaper sites in Aceh. The grouping of text documents is needed to classify news in online newspapers in Aceh based on the content contained in news articles. In this study, the process of grouping online news in Aceh was tried using the Agglomerative Hierarchical Clustering method. News is grouped with a Bottom-Up design strategy that starts with placing each object as a cluster then combined into a larger cluster based on the similarity of keywords in each news, then the cluster results are compared and put into each news category. The research design was carried out in a structured manner using data flow diagrams in forming the research framework. The study was conducted by taking online news text data on 10 online news websites in Aceh from July 2016 to March 2017 with 1000 randomly generated documents. The process of crawling news data is done using a php script which will only take text files from the news on the website. News grouping is done based on religion, politics, law, sports, tourism, education, culture, economy and technology. The results of the grouping performance of the Agglomerative Hierarchical Clustering method in this study have an average accuracy of 89.84%.

PT. Ika Bina Agro Wisesa (IBAS) is a company that produces products in the form of crude oil or CPO (Crude Palm Oil). The company sets a minimum production target of FFB that must be processed to reach 30 tons in one boiling with a minimum production target of 600 tons/day. The company is required to increase productivity. The problem so far is that the company has never measured the productivity of the production process, which will then affect the achievement of production targets. Measurement of productivity is critical because the measursizeoductivity can determine whether the company meets productivity targets for production or not. Therefore, it is necessary to measure productivity to assess the value of productivity and efforts to increase productivity in CPO production and how to increase productivity in CPO production and efforts to increase productivity using the Objective Matrix (OMAX) method at PT. Ika Bina Agro Wisesa. Analysis of productivity using the OMAX method, ratio 3 (labor productivity) and ratio 4 (machine productivity) has a very high percentage of poor performance, which means that ratio and 4 have an insufficient level of productivity. Unlike the case with the achievement of productivity ratio 1 (productivity of raw materials) and ratio 2 (productivity of working hours) wh, ich shows a low percentage of poor performance, which means that the productivity level of ratio one and ratio 2 has a better productivity level than ratio three and ratio 4 Analysis The results of the productivity index in the company decreased and increased for each month, in November it experienced a decrease of -79.49, while in December it experienced a significant increase in the amount of 595.02 and January at 69.98. in February decreased to -23.63. Furthermore, productivity in March - September 2021 was unstable, with an increase and dropped for July, a decrease of -0.64 and, a slight increase in August of 0.28.

Urban Green Open Space has important benefits for the lives of its residents. However, the problem that often arises is that there are many green open spaces in the city only as spaces that are responsive to the climate, environment, and as noise absorbers. Even though its existence is more than that, Green Open Space should also be able to fulfill the social activities of city dwellers in interacting, communicating and other social realities to create positive mental growth for fellow city residents. Architecture can be used as a vehicle to make a place not only a visual use but also can be a benefit for human life in the quality of its social reality. Therefore, research activities are needed by observing the relationship between Green Open Space and social activities of the city community as users to find the identity of the place so that the character is seen as the cause of the place to exist. The research was conducted by adopting a qualitative method that was translated descriptively at certain times in a factual manner so that the audience got a clear picture of the social reality that occurred. The results of the study explain that the pattern of activities that occur interactively on the character of the place provided contextually is intended for teenage visitors. There is no strict place limit between adolescent habitus social activities, this is a stereotype of the arena, capital, and power of adolescents who tend to be free.
