Abstract

This paper presents a simple method to reduce performance loss due to a parallel program's massive critical sections of parallel numerical integration. The method transforms a fine-grain parallel loop into a coarse grain parallel loop that nests a sequential loop. The coarse grain parallel loop is by nesting a loop block to make task granularities coarser than that naive one. In addition to the overhead reduction, the method makes the parallel work fraction significantly more significant than the serial fraction. As a result, nesting a serial loop within a parallel loop improves the parallel program's performance. Compared to the naïve method, which does not scale the performance of a parallel program of numerical integration, the nesting serial loop method scales a parallel program up to 3.26 times a fold relative to its sequential program on a quad-core processor. This result shows that the proposed method makes the parallel program much faster than the naïve method.

Abstract

Komunitas Sahabat Penyu di Dusun Mampie Kabupaten Polewali Mandar (Polman) adalah kumpulan masyarakat yang aktif dalam kegiatan pelestarian penyu dengan mengumpulkan telur penyu, melakukan penetasan, perawatan serta rehabilitas penyu guna menjaga populasi penyu yang semakin berkurang di daerah tersebut. Hal ini bertujuan untuk melestarikan penyu mengingat semakin berkurangnya populasi penyu yang ada di Polman khususnya di Dusun Mampie. Kegiatan yang dilakukan melalui pendekatan ke sejumlah pemuda dan masyarakat lainya yang selama ini aktif menjual telur penyu ke pasaran untuk tidak lagi memperjual-belikan telur tersebut. Kurangnya kesadaran masyarakat akan manajemen konservasi penyu, proses monitoring jumlah dan perkembangbiakan telur penyu yang masih bersifat tradisional serta permasalahan pendanaan yang masih sangat minim merupakan masalah yang dihadapi oleh Komunitas Sahabat Penyu. Oleh karena itu, kegiatan pengabdian ini menawarkan solusi terkait peningkatan keterampilan para anggota komunitas dalam hal Teknologi Informasi untuk peningkatan kesadaran masyarakat terkait konservasi penyu. Tujuan kegiatan Pengabdian pada Masyarakat ini adalah memberikan pengenalan keterampilan dan pelatihan Teknologi Informasi kepada komunitas Sahabat Penyu tentang pembuatan sistem informasi berbasis website dengan media Wix. Media ini adalah sebuah aplikasi yang telah banyak digunakan untuk membuat website mulai dari blog, online shop, corporate website, serta situs edukasi. Selain itu, pelatihan desain media periklanan sederhana juga diberikan, yaitu pembuatan brosur, pamphlet, poster dan flyer. Dengan keterampilan yang diperoleh dari proses pelatihan Teknologi Informasi yang diberikan oleh tim pengabdian Departemen Teknik Informatika dan Departemen Teknik Elektro Universitas Hasanuddin maka komunitas Sahabat Penyu dapat menciptakan sistem informasi komunitas yang dapat berfungsi sebagai ajang promosi komunitas untuk menjaga eksistensi sehingga otomatis dapat menumbuhkan kesadaran akan pelestarian populasi penyu dan meningkatkan donasi kepeduliaan masyarakat terhadap penyu.

Abstract

Pengabdian masyarakat dilaksanakan di SMP Negeri 1 Takalar ini bertujuan untuk memberikan wawasan baru bagi guru dan siswa terkait metode dan materi pembelajaran interaktif dengan Augmented Reality, yang diharapkan dapat meningkatkan motivasi belajar dan pemahaman siswa, khususnya mata pelajaran Biologi. Augmented Reality merupakan sebuah teknologi yang melibatkan overlay grafis komputer pada dunia nyata, dimana dunia maya tiga dimensi bisa dibawa ke lingkungan dunia nyata secara real-time. Augmented Reality merupakan salah satu teknologi yang dapat digunakan sebagai media pembelajaran. Sebagai media pembelajaran baru, maka diharapkan dapat menambah wawasan bagi para guru dan murid di SMP Negeri 1 Takalar. Selain itu, pengabdian masyarakat ini juga sebagai ajang sosialisasi hasil-hasil penelitian dari dosen dan mahasiswa pada Program Studi Teknik Elektro dan Teknik Informatika Universitas Hasanuddin. Pelaksanaan pengabdian pada masyarakat ini dibagi dalam 2 tahap, yaitu tahap sosialisasi metode pembelajaran dengan memanfaatkan teknologi Augmented Reality dengan smartphone dan tahap pelatihan penggunaan aplikasi edukasi sebagai hasil penelitian tim pengusul. Antusiasme dari kepala sekolah, guru dan siswa saat pelaksanaan kegiatan ini.

Abstract

The purpose of this service is to develop and implement Smart Card-based Smart Campus at the State Islamic Institute (IAIN) Bone. This application platform was developed using the standard Indonesian Smart Card Consortium (KSCI) with a smart card and reader chipset from PT Xirka Silicon Technology and PT. INTI. This application serves to receive, process, and visually display data sent by a card reader. Processing this data is very necessary so that the data collected can be used to facilitate the campus in recording student data electronically and use it for various campus interests. In addition, this application allows access to interoperability with applications on other campuses, for example with fellow KSCI member campuses or other campuses in this case the IAIN Bone campus. When this smart card system is running and stable, the system can be developed to enter various other applications such as ticketing, loyalty cards in various communities, and close loop payments. The implementation of community service was divided into 2 stages, namely the socialization stage about smart campus, especially smart cards and the Smart Card-based Smart Card application training phase on the IAIN Bone campus. The implementation of this activity received a positive response from the campus and has implemented two smart card systems in the campus of IAIN Bone.

Abstract

Digital village is a government program concern on village development to improve the quality of life of rural communities through the use of technology in various aspects of village development. This community service aims to provide essential insight and knowledge regarding Digital Village and its application to support the realization of a smart village. This activity was carried out in Desa Tamaona, Bulukumba Regency, through a socialization process attended by four village officials and ten productive people from the local village. Digital information about this village is still relatively minimal on the Internet, while the potential for natural wealth and products in the village is excellent. Therefore, this activity was carried out to support the concept of village digitization as well as an event to introduce the potential of Desa Tamaona to the outside community. The implementation of this service is carried out by socializing village information applications/systems using the Participatory Rural Appraisal (PRA) method. The results of the initial data collection show that the Desa Tamaona community has sufficient potential for developing a digital village, which is seen from the already high intensity of internet use by the community. After the socialization and training on using the website information system, the participants acknowledged that they got a lot of convenience in accessing information digitally compared to before this activity was carried out. This stage is a motivation for further developing technological resources to achieve the smart village concept, which can also increase digital literacy for the Desa Tamaona community.
