Abstract

The availability of document in an agency, both government and private, is important, because document contain information that can support all forms of activity in the agency. The availability of document at special higher education institutions of the faculty of engineering does not escape the role of lecturer, as people who play a role in preparing or preparing the necessary document for certain task. However, in its implementation, lecturer are sometimes often late in providing the necessary document, so that this can hinder ongoing activity. Therefore, in this study, the author created an information system to be able to monitor lecturers in providing documents. Users of this system are system administrators, deans, heads of study programs and lecturers. Based on the test results, the lecturer monitoring information system in providing documents can carry out assignment activities for lecturers, collection of assignment documents by lecturers and monitoring processes during the lecturer concerned in the assignment. With the lecturer monitoring application in providing document, the engineering faculty can monitor lecturer who have or have not collected document. The system also provides convenience for lecturer in monitoring the status of document that have been collected, whether they have been followed up or not by the faculty.

Abstract

The creation of class schedules requires a high level of precision and focus to generate the best possible timetable. A schedule with the best solution can provide comfort for both faculty and students, thus enhancing the quality of early meetings during classes. However, in the engineering faculty of Muhammadiyah University Cirebon, classes often do not start simultaneously with other faculties due to the manual scheduling process. Addressing this issue, a system is needed to automate the creation of class schedules. By implementing the Constraint Satisfaction Problems method to impose constraints before evaluating the fitness values in the Genetic Algorithm, it can assist in searching for the best solutions in accordance with the scheduling requirements of each program in the Engineering faculty. The results of black box testing on the system, item code 06, demonstrate that the system can produce schedules that comply with the requirements of each program in the faculty.

Abstract

Irrigation system management aims to realize water utilization in agriculture, which is participatory, integrated, and environmentally friendly. Kamun weir is located in Liangjulang village, Kadipaten sub-district, Majalengka District, and belongs to the Kamun irrigation area. The research entitled Analysis Performance of the Kamun Weir Irrigation Area in the Lutung Barat Canal, Majalengka Regency, aims to provide an overview and problems solving that occur at the irrigation network level, restoring and optimizing its original function. The method analyzes rainfall data for water requirements, cropping patterns, and irrigation physical conditions. The results of the analysis show that the water needs of the Kamun Lutung Barat irrigation area have been met with the existing mainstay discharge. However, there was still a shortage in May period II, where the existing mainstay discharge of 3046 liters/second was still needed to meet the demand discharge of 3423 liters/second. However, after modifying the cropping pattern with padi-palawija-tebu, the water requirement in the second period of May became 2848 liters/s, so the required water discharge has been met with the existing mainstay discharge. Irrigation channel conditions are in the medium classification with a percentage of 67.58%, and the condition of the irrigation building is in the medium classification with a percentage of 66.88%.

Abstract

Making combined materials that consist of unsaturated polyester and coconut fiber is the target of this research. The samples were tested by tensile and hardness tests before and after warm-up, and obtained by the result was that the trend value of hardness of unsaturated polyester+coconut fiber experienced proportional degradation with the addition of the composition of coconut fiber. The composition of 3% coconut fiber+97% unsaturated polyester has the highest hardness value, reaching 46,7 kg/mm2, and downhill becomes 43,1 kgf/mm2 moment heated at a temperature of 500C for 1 hour. Analog to the tensile test, 3% coconut fiber + 97% unsaturated polyester composition has the highest ultimate tensile strength and yield point. Adding fiber can boost the elasticity modulus, but the warm-up treatment causes the expansion of coconut fiber. The result is that the value of the tensile and hardness of the polyblend will go downhill.

Abstract

Energy drinks are stimulants that men or women generally use to handle sleepiness while driving with sleep deprivation. There is no study about energy drink’s effect on gender. This study aims to learn about energy drinks in different genders while driving with sleep deprivation. Research is done using a laboratory approach using a driving simulator. Ten men and ten women were participants (21 ± 0.95 years). Participants were asked to drive for 90 minutes, and before driving the simulator, participants drank coconut water or Kratingdeng based on the planned order. PVT measured awareness before and after participants used the simulator. Dependent variables measured are mean RT, %minor lapses, and mean 1/RT. EEG evaluated sleepiness during the driving session. Based on ANOVA, energy drinks did not influence mean RT (p-value = 0,088), mean 1/RT (p-value= 0,058), %minor lapses (p-value =0,571), and EEG (p-value = 0,348). Meanwhile, EEG measured sleepiness and was only influenced by gender (p-value = 0,048). Based on the test, there is no difference between the two energy drinks. It is caused by an energy drink’s material that gives the body the same stimulant level. There is a difference in Mean 1/RT between gender and energy drinks. It is caused by composition such as potassium in coconut water or taurine and caffeine in Kratingdeng. The research shows that energy drinks do not influence awareness and sleepiness while driving for 90 minutes. However, energy drinks give different results in awareness of different genders.

Abstract

The number of social media users in Indonesia has increased in recent years. The surge in social media users leads to more offensive language on these platforms. The use of offensive language can trigger conflicts between users. Therefore, it is necessary to identify the use of offensive language on social media. This study focused on identifying offensive language, hate speech, and hate speech targets on Twitter. The data used were obtained from previous research on identifying offensive language and hate speech. The amount of data is very influential on the performance of the classification. Therefore, data was added using translation in this study. Classical machine learning (SVM et al.) and deep learning (BiLSTM, CNN, and LSTM) algorithms are used as classification algorithms with word n-gram and word embedding as the features. Three scenarios were done based on the training data used in the classification model development. The result shows that scenario 3, which uses translation for data augmentation, can improve the classification model’s performance by 5%.

Abstract

This study aims to create a web-based comic reading and publishing exchange to make obtaining, reading, and publishing a comic easier. As for the background of this research, in today's modern era, when getting a comic, some people still use conventional methods, so it requires more costs, limited stock, longer time, limited storage space, and more complex maintenance and production costs—extensive distribution. Creating web-based comic reading and publication exchanges is an alternative expected to make reading comics easier and faster. Comic buyers and sellers can also easily make comic transactions because they are systemized and stored safely. Testing the reading site exchange system and web-based comic publications shows that the system has achieved the expected goals. The system can identify user roles; allows the Admin to review or confirm comics and chapters as well as manage genre and user data; provides the seller with the ability to manage data on comics, chapters, and payments; gives customers access to view a list of comics, transaction history, make purchases, and read comics; and the payment system can confirm transactions made by customers.
