Judul: Program Updates of Over The Air Programming System for Multiple IoT Devices Based on AsyncElegantOTA and AutoIT
Abstrak: Internet of Things (IoT) adalah ekosistem objek pintar dengan sensor, teknologi jaringan, dan pemrosesan yang bekerja sama untuk menciptakan lingkungan pintar bagi pengguna. IoT membantu berbagai bidang seperti industri, peternakan, dan pertanian. Perangkat IoT memerlukan fasilitas over the air (OTA) untuk memperbarui perangkat lunak tanpa terhubung langsung ke komputer. Namun, sistem OTA saat ini hanya bisa memperbarui satu perangkat secara manual, sehingga memakan waktu. Oleh karena itu, otomatisasi diperlukan agar perangkat dapat diperbarui secara bersamaan. Penelitian ini melibatkan analisis, perancangan, implementasi, dan pengujian menggunakan perangkat lunak AsyncElegantOTA dengan AutoIT untuk pemrograman OTA multi perangkat. Pengujian dilakukan dengan mengunggah lima program berbeda., The Internet of Things (IoT) is an ecosystem of smart objects with sensors, network technology, and processing that work together to create an intelligent environment for users. IoT aids various fields such as industry, livestock, and agriculture. IoT devices require over the air (OTA) capabilities to update software without direct connection to a computer. However, current OTA systems can only update one device manually, which is time-consuming. Therefore, automation is needed to update multiple devices simultaneously. This research involves analysis, design, implementation, and testing using AsyncElegantOTA software with AutoIT for multi-device OTA programming. Testing was conducted by uploading five different programs.

Judul: Karakteristik Kimia Lignin Sepuluh Jenis Kayu.
Abstrak: Lignin is a chemical component of wood which was concerned in relation to pulping process. The content and reactivity of lignin affect the easiness of delignification in the pulping process. This research aimed to analyze the chemical characteristics of lignin in the ten wood species; which were expressed as total lignin, Klason lignin, acid-soluble lignin, and syringil/guiacyl ratio. Total lignin was defined as a sum of Klason and acid-soluble lignin. Lignin content varied widely between wood species. Klason lignin was 20.51-34.3% and acid-soluble lignin was 0.31-2.8%. Wood species having lower lignin content tend to have higher acid-soluble lignin and syringil/guaiacyl ratios. Consequently, there was clear and positive correlation between acid-soluble lignin and syringil/guaiacyl ratio (R2=0.92)
