Abstract

The use of multiprocessor methods in robotics systems has a significant impact on overall robot performance. The Master-slave method is a model of a multiprocessor system where there are several processors that communicate with each other to carry out the robot's overall function. RS-485 can be used as a communication model in the master-slave method. RS-485 is a development of RS-232 which has the ability to communicate with several nodes. In this research, an experiment will be conducted to implement RS-485 to support the master-slave processor communication. Stages of research began with making system design, which includes the design of embedded hardware systems, the design of data communication protocols on RS-485 networks, software design, followed by implementation and testing. The test is carried out to measure the time response of the device to three data transmission models, namely broadcast, addressing slaves without responding and addressing slaves with responses. The test results carried out on three slaves with a communication speed of 9600 bps. Measured response time on broadcast data transmission is 8ms, and address slave without response is 7ms. Whereas delivery by addressing slaves with responses, shows that the measurement method cannot be applied.

Abstract

Sel elektrokimia berbasis mikroba atau Microbial Fuel Cell (MFC) merupakan pengembangan fuel cell yang umumnya berbahan bakar hidrogen murni. MFC menggunakan mikroorganisme sebagai katalis untuk mengoksidasi senyawa organik dalam metabolismenya dan melibatkan proses transfer elektron yang digunakan untuk memproduksi tegangan dan arus listrik. Arus listrik dapat dihasilkan bila terdapat senyawa mediator dalam kompartemen anoda yang akan melakukan penetrasi ke dalam membran plasma sel, kemudian mengambil elektron dari rantai transfer elektron mikroorganisme tersebut serta membawanya menuju ke permukaan elektroda. Penggunaan materi organik, misalnya air buangan organik, yang dapat dimanfaatkan oleh mikroba sebagai sumber energi dapat mereduksi biaya selain menjadi alternatif solusi penanggulangan air buangan organik. Tiga jenis air buangan, yakni yang bersumber dari rumen sapi, industri tahu dan industri sawit dapat dimanfaatkan sebagai substrat dan agensia mikroba pada sistem MFC. Adapun beda potensial tertinggi didapat oleh rumen sedangkan potensial listrik yang paling rendah adalah air buangan tahu.

Abstract

In exposing criminal acts, it is necessary to have a concrete piece of evidence, one of which is by using the role of fingerprints. Police fingerprint identification uses supporting tools such as the INAFIS Portable System (IPS). The process of reading fingerprints using this IPS tool, usually decreases image quality which causes obstacles in reading or analyzing fingerprint patterns. Nowadays digital image processing techniques have been widely used to conduct analysis and pattern recognition. This of course, can be used to perform fingerprint pattern recognition based on texture characteristics. In this study, a system was created that was able to recognize the types of fingerprint patterns as a form of digital technology development (image processing). In this analysis system research, the Gray Level Co-Occurence Matrix (GLCM) method is used by utilizing feature feature extraction by paying attention to the pixel relationship and Multi-Class Support Vector Machine (Multi-SVM) as an introduction to fingerprint pattern types. The data used in this study were fingerprint images of scanning results from IPS tools in the form of arch, left loop, plain whorl, right loop, and twinted loop patterns. Testing this analysis system produces varying degrees of success. The average success rate on this system uses training data which is 91.6% with the highest percentage success rate of 100% in the type of arch, left loop, and plain whorl pattern. While the average success using test data is 66% with the highest percentage success rate of 100% in the arch pattern type.

Abstract

Abstract– Konsep pertanian terpadu yang melibatkan tanaman dan ternak sudah lama diterapkan oleh petani di Indonesia, namun penerapannya masih secara tradisional, tanpa memperhitungkan dari aspek secara finansial maupun dalam konteks pelestarian lingkungan hidup. Konsep sistem tanaman-ternak dilakukan dengan mempertimbangkan aspek-aspek keberlanjutan (sustainable) yang ramah lingkungan (environmentally tolerable), secara sosial diterima masyarakat (socially acceptable) dan secara ekonomi layak (economically feasible). Pendekatan yang dilakukan adalah penggunaan input dari luar yang rendah yang dikenal sebagai LEISA (low external input sustainable agriculture). Adanya dukungan teknologi dalam pendekatan LEISA untuk integrasi usahatani tanaman hortikultura-ternak diharapkan dapat mengembangkan agribisnis yang berkelanjutan dan menciptakan lapangan kerja yang bersumber pada usaha dengan memanfaatkan sumberdaya lokal khususnya limbah peternakan dan pertanian secara lebih efisien. Limbah kotoran ternak sapi dapat diolah menjadi energi dan pupuk organik sehingga dapat mendukung usahatani tanaman hortikultura. Sedangkan limbah usahatani tanaman hortikultura dapat diolah menjadi sumber pakan ternak bagi peternakan sapi. Apabila proses integrasi tanaman hortikultura dan ternak sapi dapat berhasil dengan baik, tidak mustahil akan terjadi peningkatan produksi dan produktivitas, yang pada gilirannya akan tercapai pengembangan agribisnis yang berkelanjutan.
