Abstract

This study was conducted to examine the supplementation of green meniran herb extract (Phylanthus niruri L) and kaffir lime leaf extract (Cytrus hystrix D. C.) on the appearance of free-range chicken semen. The study was conducted using a completely random design of unidirectional patterns, using 24 male free-range chickens aged about one year with an average weight of 1.8 kg with eight treatments, three replicates each. Each replicate consisted of 1 chicken. Basal feed uses BR-1 chicken feed produced by PT. Japfa Comfeed Indonesia Tbk. After 1 week of basal feeding, chicken sperm was taken and tested for control (H-0), then began to be treated with testosterone supplementation, as a positive control, meniran extract, kaffir lime leaf extract, or a mixture thereof.  The following semen collection is carried out after 1 week of treatment. Semen collection is carried out every 3 days with five intakes. This study concludes that the supplementation of green meniran herb extract and kaffir lime leaf extract or a combination thereof, macroscopic, does not change the appearance of free-range chicken semen, both volume, color, consistent odor, and pH of semen, but microscopic significantly increase sperm concentration, motility, and Viability. There was no synergy between green meniran herb extract and kaffir lime leaf extract on the appearance of chicken semen.

Abstract

Air quality monitoring is one of the important steps in maintaining public health and the environment. With the development of Internet of Things (IoT) technology, air quality monitoring can be done in real-time and more efficiently. This study aims to environmental policy and design of an IoT-based air quality monitoring system using the ESP32 microcontroller. This system is designed to measure air quality parameters such as CO, NO2, temperature, and humidity using factory-calibrated sensors (DFRobot) connected to the ESP32 microcontroller. Data obtained from the sensors are processed by the ESP32 and sent to a cloud server via Wi-Fi, allowing real-time monitoring via the ThingSpeak platform which can be monitored via mobile devices or the web. The results of the air quality monitoring system design show that devices using electrochemical CO and NO sensors₂and the SHT30 sensor connected to the ESP32 is capable of reading and measuring CO, NOconcentrations., temperature, and humidity with good accuracy with a sample time of ± 20 seconds. In addition, this system can be connected online with the ThingSpeak platform, allowing visualization of measurement data in graphical form in real-time. Thus, the designed system not only functions optimally in detecting air quality parameters, but also supports efficient remote monitoring through Internet of Things (IoT) technology

Abstract

This study aims to analyze the effect of ozonation treatment on the immune activity of vannamei shrimp, compared to non-ozonization treatment. Parameters measured include Total Haemocyte Count (THC), Differential Haemocyte Count (DHC), and phagocytic activity. The results show that ozonation treatment produces higher THC values, namely an average of 75% more than non-ozonation. The DHC value in the ozonation treatment showed an increase in granular cells by 40% compared to the non- ozonation treatment. In contrast, hyaline cells decreased due to a more active immune response against pathogens. Phagocytic activity in the ozonation treatment reached 15%, higher than non-ozonization which only reached 10.33%. These data indicate that ozonation plays an important role in improving shrimp's immune response by reducing the water's pathogen content and minimizing stress. In conclusion, ozonation was proven effective in increasing the immunity of vannamei shrimp by supporting key immunological parameters.

Abstract

Understanding programming algorithms, is a basic competency that must be mastered by high school students in informatics subjects. However, students have difficulty in mastering programming algorithm material as seen by the learning outcomes of students who are still below the KKM, the use of learning media is still conventional (ordinary printed books, whiteboards, limited teaching modules, LCD projectors as well as power points). This research uses the Research and Development (R&D) research method with the 4D development model which consists of 4 stages, namely define, design, development, and disseminate. The data analysis technique used is descriptive data analysis to describe the validity, practicality, and effectiveness of the developed learning media. The results of this development research are informatics e-modules. The results of feasibility validity media experts in the very feasible category, the results of feasibility validity material experts in the very feasible category, the results of practicality teachers in the very practical category, the results of practicality testing by students in the very practical category, and the results of Paired Samples Test testing obtained data Sig < 0.005 (0.001 < 0.005), Tcount > Ttable (3.734 > 20.040) means effective, so this media is valid, practical, and effective to use as learning media.

Abstract

Indonesia is a country with a tropical climate. Rainfall in Indonesia is quite high and greatly affects the growth of mushrooms (fungi). The use of wood cannot be separated from the manufacture of traditional houses. These traditional houses made of wood are very susceptible to fungal attacks. Wood or wood rot fungi are fungi that live attached to decaying trees, but some types of wood fungi grow on living tree trunks and on dead trees. Wood rot fungi are heterotrophic, or do not produce their own food, This study aims to determine the resistance of white teak wood (Gmelina arborea Roxb) against wood-decay fungi. The research method used was a completely randomized factorial design consisting of two factors: factor I (wood) and factor II (fungi). The test samples used for the combination of the two factors measured 5x 2.50x1.50 cm, with a total of 9 test samples placed in culture jars separately. All samples from the base, middle, and tip tests were placed into a jar containing PSA media, and the inoculated mushroom culture was added to the jar. The observed parameters used an analysis of variance to determine whether the treatment had a significant effect on the decrease in teak wood weight. The Least Significant Difference (LSD) test was carried out to determine whether there were significant differences between treatments or not.

Abstract

One of the most intriguing results related to angle trisectors in convex quadrilaterals is Morley's Theorem, which several authors have subsequently extended to non-convex quadrilaterals. Numerous studies have explored the side lengths of angle bisectors, angle trisectors, and the area ratios formed by angle trisectors in both convex and non-convex quadrilaterals. However, no research has discussed the problem of angle trisectors in butterfly quadrilaterals. Therefore, this paper aims to extend the concept of angle trisectors to butterfly quadrilaterals. Various other quadrilaterals will be formed from the construction of these angle trisectors. By employing the concept of concyclic, we will demonstrate the existence of several concyclic quadrilaterals arising from this trisector construction. Triangle angles in butterfly quadrilaterals in geometry play an important role in physics. Geometry provides a visual and mathematical language that allows us to describe, analyze, and understand various physical phenomena.
