Abstract

Cows are one of the livestock whose existence can meet various kinds of human needs because they are the main producer of animal protein such as meat or milk. However, there are problems that cause failure in running a cattle farm. One of the problems is the health factor of the cattle which is disturbed due to a disease. Limited knowledge and livestock health workers become an obstacle for cattle breeders in analyzing the possibility of disease affecting cattle based on the symptoms that appear. For this reason, an expert system was built that can diagnose cow disease based on a website which can later be an alternative when someone has limited access to experts to diagnose the disease he is suffering from. The dempster-shafer algorithm was chosen because it is able to provide certainty in performing diagnostic calculations. From the results of this study, an expert system for diagnosing cattle disease has been developed using the PHP programming language which can implement the algorithm and can run well, as evidenced by passing the testing phase using the black box test method and also successfully passing the accuracy test with experts. with a percentage of 86.67%.

Abstract

Many people choose cats as pets. Cats can benefit humans, but when cats are sick, they can suffer damage, just as cat disease does in humans. Lack of knowledge about the management of cats is one of the leading causes of the high incidence of diseases in cats. The wonosobo area, the cat keeper and the abundance of wild cats, is no exception to the knowledge and insight needed in caring for good cats, and even the number of experts and animal clinics in particular is small. Therefore it requires a system that supports the role of a veterinarian in treating cat diseases, where it can quickly and accurately diagnose diseases in cats based on symptoms of diseases in cats based on previous medical summarizations. Systems built on websites for accessibility and usage. The system's accuracy rate reached 90%, with a 95% f1 score to give the overall size of a model.

Abstract

Lack of animal habitats in nature caused by several human activities such as logging, hunting and land conversion causes animals to lack places to live, which in turn results in a decline in wildlife. At this point conservation efforts are made in order to save animals from extinction. Zoos are a type of ex-situ conservation effort that can be a forum for interaction between humans and animals, so that humans can learn about animals and build close relationships with animals. On the other hand, the zoo can also be a tourist attraction so that it can become an asset for the region to develop its tourism. Referring to these matters, planning a zoo in Wonosobo Regency can become a place for animals and become a new tourist attraction while still paying attention to ecological factors so that it continues to provide comfort for humans and animals in it and does not damage the surrounding environment.

Abstract

Stadiums are the most influential supporting facilities for the sport of football in the world. Having a stadium can add pride to an area. Gelora Wonosobo Stadium is a football stadium in Wonosobo district as well as a stadium that will be used as the headquarters for the PSIW football club (Wonosobo Indonesian Football Association). The club, which has the nickname Laskar Kolodete, was previously headquartered at the Kalianget Stadium which is adjacent to the Kalianget Recreation Park and has not yet received proper stadium facilities and also cannot be called a stadium considering how it is now, therefore the Gelora Wonosobo Stadium was built which is located on Jalan Wonosobo. Kertek is opposite the Dewasni Café Restaurant, the choice of location also takes into consideration several things, namely land use, accessibility, supporting facilities for the surrounding environment and city utilities so that it will make it easier for stadium users. Gelora Wonosobo Stadium is a district class B type stadium which has FIFA standard facilities and has a capacity of approximately 20,000 spectators with a distribution of 400 VIP/VVIP spectator seats, 18,600 general spectator seats, 1000 disabled spectator seats which is 5% of the general spectators. The Gelora Wonosobo Stadium will adopt a modern, futuristic architectural style and without an athletics track. With the absence of an athletics track, the distance between the field and the stands will be closer, so there will be a distance between the stands and the field or a safety zone to see the less orderly behavior of the Indonesian people.

Abstract

In the ever-evolving digital age, the use of digital images has become a significant and widespread phenomenon in various fields. Digital image processing and understanding has become an important requirement in various applications, including pattern recognition and computer vision. On the other hand, the sustainability and understanding of cultural treasures, such as Gamelan, is becoming increasingly crucial. UNESCO has recognized Gamelan as Indonesia's 12th World Intangible Cultural Heritage, reminding us of the responsibility to maintain and preserve this cultural heritage. In the digital era, where interest in traditional musical instruments is declining, Convolutional Neural Network (CNN) is implemented as a solution to classify Gamelan musical instrument types based on visual patterns in images. CNN, implemented in an Android system, showed good results with accuracy reaching 98% in the model test stage and 79% in the Android application test. The classification model using TensorFlow Lite, specifically MobilNetV2, was able to recognize Gamelan musical instrument types in the training dataset. However, it should be noted that this model is limited to that dataset. This research contributes to the merging of technology and cultural heritage, enabling the use of technology to enhance cultural understanding and sustainability.

Abstract

In the assessment of existing reinforced concrete buildings, the compressive strength of concrete, , is a key parameter for performance assessment. The most accurate way to identify it is by conducting compressive strength tests on core concrete samples from structural elements obtained through drilling. The more samples taken, the more accurate the determination of for structural modeling will be. However, sampling in buildings certainly disrupts activities within the building, compounded by drilling marks that leave traces even after repairs. Therefore, sample collection must be selective, yet the results must still provide confidence as input for structural analysis. A method for estimating using the ultrasonic pulse velocity test, UPVT, categorized as a Nondestructive Test, NDT, has long been used and continues to be developed. Various building regulations state that NDT for estimating should be paired with the results of compressive strength tests on core concrete samples to obtain correlation between them. The relationship equation between wave propagation velocity, , and varies between studies, indicating that besides , there are other influencing factors. In this study, samples were taken from 5 (five) buildings of different ages. In addition to , the effects of density, , and age, , were examined. The results of the study indicate that has no effect, while influences the relationship between V and according to the equation with .

Abstract

The road management regulation aims to achieve reliable and excellent road services that prioritize the interests of the community by ensuring the functional and competitive performance of the roads, as well as community participation in road management in accordance with Republic of Indonesia Law No. 2 of 2022. As part of the community, when crossing the Tegineneng Bridge on the Tegineneng-Sp. Tanjung Karang road section in Lampung Province and feeling discomfort from the bridge vibrations, participating individuals conducted vibration measurements using 2 smartphones. The gyroscopes in the smartphones, packaged within a g-force application, were capable of recording real-time vibrations in a user-friendly manner, and the output data was compatible with existing modal analysis software. Subsequently, vibration data recordings using the SSI algorithm yielded dynamic parameters such as a natural frequency of 2.009Hz and a damping ratio of 7.927%. The frequency of 2.009Hz for a span of 60m is lower compared to bridges of the same span from the dynamic bridge test regression equation in Indonesia, which is 2.347Hz. Under these conditions, it is estimated that the Tegineneng Bridge experienced minor structural damage with a damage level of 14.1% and its capacity is lower by 28.2% than the empirical estimate. The damping ratio exceeding 5% is estimated to be due to excessive energy dissipation through cracks in the concrete or through defects in the connections between steel frame elements. It is recommended that relevant stakeholders conduct a detailed inspection of the bridge to ensure its safety and undertake necessary measures to guarantee the safety of its users.
