Abstract

Equine Influenza (EI) is a highly contagious respiratory infection disease in equidae caused by two subtypes of Influenza A Virus (H7N7 and H3N8). Indonesia is recently importing high amounts of horses from The Netherlands intended for equestrian sports, pets, and breeders. This study was aimed to discover the presence of Equine Influenza Virus (EIV) and antibody titres against EIV in imported horses from the Netherlands using Reverse Transcription-Polymerase Chain Reaction (RT-PCR) and Enzyme-linked Immunosorbent Assay (ELISA) techniques. The results obtained were then compared to imported horses’ data. A total of 199 nasopharyngeal swabs and 55 blood samples were collected. The results showed no material genetic of EIV was found in horses imported from the Netherlands, not all recently imported horses had antibodies against EIV, it’s indicated that the imported horses need to be measured the antibody post vaccination before arrived in Indonesia.Keywords - Horse, Equine Influenza, The Netherlands, PCR, ELISA

Abstract

The increasing population growth every year results in many problems, the problem that arises is the increasing amount of waste in the form of human feces that is thrown into septic tanks. Large amounts of human feces can be found, such as in Islamic boarding schools with the number of students continuing to increase, causing the amount of feces to also continue to increase. The problem of human feces can be overcome by utilizing feces into biogas. Utilizing biogas is a solution to replace fossil fuels and also prevents human waste from polluting the environment. The aim of the research is to find out the potential amount of student feces, find out the biogas produced using the anaerobic method, find out the results of converting biogas to LPG fuel and electrical energy and compare the costs of the energy conversion process so as to save the operational costs of the Islamic boarding school. The amount of feces produced from 59 people was 14.75 kg/day with the biogas obtained being 0.068 m3/day, the conversion of biogas to LPG fuel as much as 0.03128 kg/day, the electrical energy produced was 223,892 kJ/day, the result of converting biogas to electrical energy is 0.06224 kWh/day, the cost of saving gas fuel is IDR. 33,456 and the cost of saving electrical energy is Rp. 2,524. So the result of using biogas from human feces is that the greatest energy obtained is electrical energy, while the greatest savings are gas fuel.Keywords - Human Feces, Gas Fuel, Electrical Energy, Biogas, Anaerobic Methods.

Abstract

In 2022, the University Al Azhar Indonesia (UAI) was in the second phase of expansion, focusing on increasing the influx of new students. Each year, UAI allocated funds to execute diverse promotional strategies. However, the effectiveness of the undertaken promotional measures is deemed suboptimal, as the student admissions continue to exhibit fluctuations. To address this issue, researchers have employed the data mining method utilizing the K-Means Clustering algorithm. This study adopts both qualitative and quantitative approaches. Following the data cleaning stage, the initial sample size of 4,342 students is reduced to 2,650. The K-Means Clustering analysis identifies three clusters: the main cluster, minimum cluster, and adaptive cluster. Based on the characteristic data within the first cluster, it is recommended that UAI prioritizes promotional efforts towards students from private high schools in the Jabodetabek area. Additionally, the marketing communication mix, including brochures, banners, printed media, television, and radio, needs to be reassessed. In executing promotional strategies, UAI is advised to carefully consider the unique characteristics of each cluster and to maximize the utilization of social media and websites by incorporating elements of the 7C Framework.Keywords - K-Means, Clustering, Promotion Strategy

Abstract

Plastic to Solar (PLATOS) machine is a machine that processes plastic waste or used oil into fuel through a pyrolysis process. Based on observations made, pure diesel produced by the PLATOS machine has a very cloudy color or brownish black. Therefore, to get clearer fluid, a purification process is needed, one of which is by using bentonite powder. Bentonite powder used is Bleaching Earth Bentonite which can bind or absorb dirt and unwanted materials in oil or diesel, so that oil or diesel becomes paler and clearer. The heating method is used in the purification trial using a blow torch fire flame gun and an aluminum pan as a diesel fuel container. This study aims to observe the extent of the effect of using bentonite to improve the quality of diesel fuel that has been produced. The research was conducted by conducting 4 times the purification process with the same amount of bentonite and diesel weight of 20 grams and 1 liter. Based on the experiments that have been carried out, it can be concluded that the diesel produced has specifications that are within the limits of diesel specifications set by the Director General of Oil and Gas. Overall, the results of these specifications can state that the use of bentonite powder with heating methods up to 100o C can improve the quality of diesel fuel well.Keywords – Bentonite, Purification Process, Pyrolysis, Solar.

Abstract

The FSO communication system is a communication system that uses the atmosphere as a propagation medium for light, which is used as an optical source to transmit data to the receiver. Due to using the atmosphere as a propagation medium causes the FSO communication system to be susceptible to signal weakening caused by varying atmospheric attenuation. So, it is necessary to conduct research on FSO performance based on atmospheric conditions. This research carried out communication design using FSO technology in Pekanbaru City, analyzing the influence of rainy weather and wind data using FSO MIMO. After analyzing and optimizing the parameters contained in the FSO device to achieve the best FSO performance. The design simulation was carried out using optisystem software for Free Space Optics (FSO) analysis using the FSO MIMO technique in rainy and windy weather in Pekanbaru City. One of the impacts of using the atmosphere as a propagation medium is large attenuation. The variables analyzed by the researchers were the rain variable and the wind variable. If the laser uses power up to 10 mW at a frequency wave of 1550 nm. The simulation results of the four-channel FSO MIMO system are able to provide a maximum beam distance of up to 2 km in rainfall conditions and 8 km in windy conditions. This value was obtained through analysis of the BER and Q-Factor values in the simulation results.Keywords - FSO-MIMO, BER, Optisystem

Abstract

Wedang uwuh developed into a ready-to-drink beverage which began to be produced commercially. Determination of shelf life needs to be done to determine the time span and provide quality assurance from the start of production until it is not acceptable to consumers. One of the factors that influence changes in quality is temperature. The main parameters used are pH and color which are considered to most affect the chemical and physical quality of a product. The purpose of this study was to determine changes in pH and color during storage and the shelf life of ready-to-drink Uwuh Wedang. The shelf life estimation method used is the Accelerated Shelf Life Testing (ASLT) Arrhenius approach with storage temperatures of 40°C, 50°C and 60°C thereby accelerating quality degradation. Observations every day - 0, 3, 6, 9, 12, and 15 with three repetitions. Color analysis uses two-way analysis of variance (ANOVA). The research data showed that the shelf life of wedang uwuh ready to drink blanching treatment sequentially at 40°C, 50°C, and 60°C was 18, 15, and 12 days. While wedang uwuh ready to drink non blanching sequentially, we have 10, 9, and 9 days. Storage temperature and time have a significant effect on the color change of ready-to-drink blanching and non-blanching wedang uwuh. Ready-to-drink Wedang Uwuh turns red to brownish orange and the color of Wedang Uwuh ready to drink from blanching treatment is brighter than non-blanching.Keywords - Quality, Temperature, Ready to Drink, Shelf Life, Wedang Uwuh.
