Spam on Instagram (IG) is generally a comment that is considered as irritating because it does not relate to the photos or videos which were commented. Spam on comment section can cause some negative impacts such as making it difficult to follow the discussion on the posted status and making someone’s photo or video looks very popular, commented by a lot of followers despite the fact that most of the comments are actually spam. This research tries to build a model that can identify spam comments on IG. The comment on IG is in text format, so in this research, we use text processing methods. We use Support Vector Machine (SVM) for spam identification. The comment data used in this study were collected from Indonesian actors and artists who are the most followed accounts in IG. We have tested the spam identification model using SVM method resulted in 78.49% of accuracy. This result is better than the baseline model using NB method (77.25%). This research also tested some of the different training data proportions and SVM remains better than NB. Another result of this research are some adaptations needed for preprocessing and stemming stages that must be customized to support Unicode characters and unique symbols that commonly found in IG comments section.

Bebayuhan Oton is a ceremony that is believed to Hindu in Bali can neutralize the negative influence of someone's birth day including the character, nature and behaviour according to the Balinese Calendar. This ceremony uses a kind of upakara (ceremony tools and equipment) called banten. Banten bayuh oton or bayuh oton ceremony equipments can be knownby asking bayuh oton expert or Sulinggih (Religious Leader in Bali). However, the time needed to prepare this ceremony is less effective and efficient. The reason is the difficulty of arranging the meeting time with the Sulinggih and the lack of knowledge about bayuh oton ceremony, so it needed an application that can facilitate the search of information related to bayuh oton ceremony also can be used as guidance in the implementation of the ceremony. The information system about bebayuhan was built to facilitate Hindus' community to obtain information about bebayuhan oton. The modeling system used is a tree diagram to connect the procession of bebayuhan oton ceremony with banten and other necessary tools. This system displays the data including the procession, banten as well as the facilities as a complement ceremony

Submission of learning materials with animal themes, especially wild animals to early childhood becomes a challenge for teachers. Two-dimensional displacement media in the form of a monotonous image has the potential to decrease interest in children's learning. Bringing wild animals directly or bringing the children to the zoo requires considerable cost and time and harm. Based on these problems, the authors develop android-based applications that contain fourteen species of wild animals in 3D format that is packed with Virtual Reality (VR) technology. The authors develop applications using development research methods with the ADDIE model. The developed VR application is capable of displaying wild animal animations complete with the sounds and environment of the habitat, as well as the description narrative features and food that can be viewed in 3D and VR modes. The test results showed that the application received a positive response from users, especially children in TK Negeri Pembina Singaraja. The average percentage for the user response test is 88.50%, which means it is very good where children can know the types of wild animals, the movements of wild animals, the sounds of wild animals, the habitats of wild animals and can use them easily.

Identification technology has been widely developed today, such as fingerprint identification, palms and face. Identification is the determination of a person's identity and the process of identifying is an activity in determining or establishing a person's identity. Development of this identification technology has been applied to various devices one of them on Android based smartphone. Most of the development of Android based identification is still use storage technology on the device itself. The Eigenface method is used to extract the relevant information from a face image, then convert it into the most efficient set of codes and the code is compared to the code from the properties it has stored in the database. Face Identification Application Android Based is built by using storage technology on the server (MySQL) and also use the Eigenface Method. The success rate of face identification test results was 68% and the false accept rate of 32%, of the total trial was 25 times identification. Some important factors that influence the success rate of identification are the position of the face and the intensity of light during enrollment.

Forecasting the electrical load becomes important, because it can estimate electricity consumption over a certain time range. Accuracy in electric load forecasting can improve safety and reliability in the operation of power systems such as load flow, maintenance of generating units and scheduling of generating units. In this study used case study system Sulselrabar, which is currently growing, but still not much to discuss about the condition of the current system and which will come. Several methods for predicting electrical loads have been widely used, ranging from conventional to smart-based methods. In this research will be proposed method of artificial intelligence for forecasting Short Term load on Sulselrabar system. The method used is based Fuzzy Logic and Cuckoo Search Algorithm. The combination of Fuzzy logic and Cuckoo Search methods is chosen because the combination of both optimizes optimum fuzzy logic membership, so the forecasting results have a very small error. From the results of the research can be concluded that the result of load forecasting using Fuzzy Logic method optimized using Cuckoo Search Algorithm (FL-CSA) is better than Fuzzy Logic that is not optimized. The analysis results using input data 3 months before day H, to predict the load for one week on January 1 to 7 january 2014, and as a comparison used the predicted day H data. From the simulation results, the mean absolute percentage error (MAPE) is smaller using FLCSA, for the smallest MAPE on 1 January 2014 of 0.06785208%. While the highest MAPE on January 4, 2014 amounted to -0.44973%.
