Judul: Pembaharuan Program Over The Air pada Banyak Perangkat Iot Berbasiskan AsyncElegantOTA dan 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 Kayu Reaksi Ulin (Eusideroxylon zwageri T. et B.)
Abstrak: Reaction wood which formed in hardwood generally has a lower klason lignin content, higher acid soluble lignin content, and higher syringil unit than opposite wood. Ulin wood (E. zwageri) contains high klason lignin and low acid soluble lignin contents which closed to lignin characteristic of softwood. This experimental aimed to study the difference of chemical characteristic of reaction wood (klason lignin content, acid soluble lignin content, and lignin monomer composition) and polysaccharides content which formed in E. zwageri stem. Visually, the reaction wood part was formed in upper side of leaning stem. Klason lignin content in reaction wood part was lower (32.71%) than opposite wood part (33.74%). However, the lowest lignin content was found in the side wood part (28.15%). Lignin of E. zwageri was composed by syringyl and guaiacyl monomer with average of syringil to guaisyl ratio 0,2. Acid soluble lignin content in E. zwageri was very low (0.69%) that positively correlated with the proportion of syringil unit in lignin. Polysaccharide content of reaction wood part (63.66%) was higher than opposite wood part (62.88%), but the highest content polysaccharides presented in the side wood part (64.19%).
