Sistem Pembayaran Tiket Bus Rapid Transit (Brt) Menggunakan Near Field Communication (Nfc)s

Angkutan umum yang sedang berkembang di Indonesia saat ini adalah Bus Rapid Transit (BRT), salah satunya di Kota Padang, Sumatera Barat yang dinamakan dengan Bus Trans Padang. Sistem pembayaran tiket pada Bus Trans Padang saat ini masih kurang efektif karena dilakukan dengan pembayaran uang tunai dengan rata-rata waktu transaksi 20,13 detik dan menggunakan kartu Brizzi dengan rata-rata waktu transaksi 13,02 detik. Pada penelitian ini dirancang sebuah sistem pembayaraan dengan memanfaatkan teknologi Near Field Communication (NFC). NFC-Reader dipasang pada pintu masuk halte dan penumpang hanya perlu mendekatkan NFC tag yang ada di dompet ataupun tas ke NFC-Reader sehingga pintu halte akan terbuka secara otomatis ketika transaksi berhasil dilakukan, dengan rata-rata waktu transaksi 5,38 detik. Dengan sistem yang dibangun, waktu transaksi pembayaran tiket menjadi lebih cepat dan saldo pengelola secara otomatis bertambah seiring dengan pengurangan saldo penumpang setiap transaksi berhasil dilakukan

CURATION AND MANAGEMENT OF CULTURAL HERITAGE THROUGH LIBRARIES

Libraries, museums and archives hold valuable collections in a variety of media, presenting a vast body of knowledge rooted in the history of human civilisation. These form the repository of the wisdom of great works by thinkers of past and the present. The holdings of these institutions are priceless heritage of the mankind as they preserve documents, ideas, and the oral and written records. To value the cultural heritage and to care for it as a treasure bequeathed to us by our ancestors is the major responsibility of libraries. The past records constitute a natural resource and are indispensable to the present generation as well as to the generations to come. Libraries preserve the documentary heritage resources for which they are primarily responsible. Any loss of such materials is simply irreplaceable. Therefore, preserving this intellectual, cultural heritage becomes not only the academic commitment but also the moral responsibility of the librarians/information scientists, who are in charge of these repositories. The high quality of the papers and the discussion represent the thinking and experience of experts in their particular fields. The contributed papers also relate to the methodology used in libraries in Asia to provide access to manuscripts and cultural heritage. The volume discusses best practices in Knowledge preservation and how to collaborate and preserve the culture. The book also deals with manuscript and archives issues in the digital era. The approach of this book is concise, comprehensively, covering all major aspects of preservation and conservation through libraries. The readership of the book is not just limited to library and information science professionals, but also for those involved in conservation, preservation, restoration or other related disciplines. The book will be useful for librarians, archivists and conservators. We thank the Sunan Kalijaga University, Special Libraries Association- Asian Chapter for their trust and their constant support, all the contributors for their submissions, the members of the Local and International Committee for their reviewing effort for making this publication possible

Sediment Organic Matter Content and Macrozoobenthos Abudance in the Estuary of Kambang Pesisir Selatan District West Sumatera

Around the Kambang Estuary, there are fish shelters (TPI), fishing boat ports, residential areas, and mangrove ecosystems. This causes a decrease in water quality due to the increase in organic matter, which has an impact on the life of macrozoobenthos. The study conducted in February 2021 aims to analyze the organic matter content of sediments, identify the type and abundance of macrozoobenthos and the relationship between sedimentary organic matter and the abundance of macrozoobenthos. Determination of stations using purposive sampling method. This research was carried out at 4 stations with 4 sampling points. The results showed that the organic matter content found varied from 4.23 to 8.47%. The abundance of macrozoobenthos ranged from 13.89 to 38.89 ind/m2. The species of macrozoobenthos found at the study site consisted of 8 species from 3 classes of bivalves, gastropods and malacostraca. The relationship between the organic matter content in the sediment and the abundance of macrozoobenthos is obtained by the equation Y = 22.734 + 0.319X, where the coefficient of determination (R2) is 0.003 and the correlation coefficient (r) is 0.054, which is a very weak shows correlation

Implementasi Teknologi Nfc untuk Recording Data Sapi Perah Kelompok Tani Lembu Alam Serambi Kota Padang Panjang

One of the efforts in increasing the productivity of dairy cows is to apply maintenance management to dairy cows in the form of recording livestock data. Lembu Alam Serambi farmer group has a recording system using livestock cards provided by the Animal Husbandry Department. Cattle cards used for data recording of dairy cows are made from a type of paper that has several disadvantages, namely, easily lost, torn, wet, burned, and dirty. Therefore, to overcome this problem, we apply Android using Near Field Communication (NFC) technology. In this community service, the NFC technology implementation system is integrated with cow's ear tag and android application. This system is used to identify dairy cows and process data recording with an Android-based application. In this cow data recording system consists of two mobile apps, namely cow data record application and NFC tap tag application. The system implementation shows that the community service activity can help facilitate the Lembu Alam Serambi farmer group in the process of recording dairy cattle data

Ekstraksi dan Karakterisasi Mikroselulosa dari Rumput Laut Coklat Sargassum SP. sebagai Bahan Penguat Bioplastik Film

Sargassum sp. merupakan rumput laut coklat yang banyak tumbuh disepanjang pantai Indonesia. Tujuan dari penelitian ini adalah mengekstraksi mikroselulosa dari rumput laut coklat Sargassum sp. yang diambil dipantai daerah Banten. Selulosa dan mikroselulosa diekstraksi melalui dua tahapan yaitu proses alkalinisasi dengan kalium hidroksida (KOH) dan dilanjutkan proses hidrolisis dengan asam sulfat (H2SO4). Variable konsentrasi optimal KOH untuk menghasilkan selulosa adalah 0,1%, 0,7% dan 1,3% (b/v), dengan karakterisasi gugus fungsi produk menggunakan Fourier-Transform Infra Red (FTIR). Hasilnya menunjukkan bahwa pola spektrum FTIR selulosa dengan alkalinisasi pada konsentrasi KOH 0,1% dan 0,7%, (b/v) berbeda dengan pola spektrum selulosa dengan konsentrasi KOH 1,3% b/v Optimalisasi proses hidrolisis untuk menghasilkan mikroselulosa dilakukan dalam H2SO4 1 M dengan variabel kecepatan pengadukan 1000 rpm, 1500 rpm, dan 2000 rpm serta variabel waktu proses 30 menit dan 90 menit. Spektrum FTIR mikroselulosa dari semua variabel menunjukkan pola yang sama. Bentuk permukaan selulosa hasil foto Scanning Electron Microscope (SEM) dengan pembesaran 100.000 kali terlihat seperti bulatan, sedangkan mikroselulosa berbentuk garis panjang. Penambahan mikroselulosa pada bioplastik pati tapioka/kitosan menghasilkan bioplastik yang lebih tahan terhadap air dibuktikan dengan sisa bioplastik lebih panjang dibanding blanko setelah direndam selama 8 hari
