Judul: Characteristics of plywood made of  Furfurylated Veneer of Hevea brasiliensis Bonded with Polyurethane and Epoxy  Adhesives
Abstrak: Penelitian ini menyelidiki karakteristik kayu lapis berbahan vinir kayu karet (Hevea brasiliensis) terfurfurilasi pada berbagai tingkat modifikasi. vinir kayu karet terlebih dahulu diimpregnasi dengan furfuril alkohol (FA) pada konsentrasi yang berbeda, yaitu 40%, 70%, dan 100%, dengan asam sitrat 3% sebagai katalis untuk polimerisasi FA pada suhu 103°C. Persen peningkatan berat (WPG), sifat mekanik dinamis (DMA), dan gugus fungsi vinir terfurfurilasi dianalisis. Vinir terfurfurilasi yang dihasilkan kemudian dibentuk kayu lapis dengan menggunakan poliuretan atau resin epoksi sebagai perekat. Beberapa sifat fisik, mekanik, dan morfologi kayu lapis furfurilasi dikarakterisasi. Furfurilasi sedikit menurunkan kekuatan ikatan kayu lapis berperekat PU pada FA 100%, sedangkan kayu lapis berperekat epoksi tetap tidak berubah untuk semua konsentrasi FA. Furfurilasi meningkatkan ketahanan kayu lapis terhadap delaminasi terutama pada perlakuan menggunakan FA 40% dan 100%. Pembentukan kayu lapis terfurfurilasi pada penelitian ini membuka peluang potensial penggunaan vinir berkualitas rendah dari jenis kayu cepat tumbuh untuk menggantikan vinir berkualitas tinggi dari hutan alam., This study investigated the properties of plywood made from furfurylated rubberwood (Hevea brasiliensis) veneer at different modification levels. Rubberwood veneers were impregnated with furfuryl alcohol (FA) at different concentrations of 40%, 70% and 100%, using 3% citric acid as a catalyst for FA polymerisation at 103°C. The percentage weight gain (WPG), dynamic mechanical properties (DMA) and functional groups of the furfurylated veneers were analysed. The resulting furfurylated veneer was then used to form three layers of plywood using polyurethane or epoxy resin as an adhesive. Several physical, mechanical and morphological properties of the furfurylated plywood were characterised. Furfurylation slightly decreased the bond strength of PU-bonded plywood at 100% FA, while epoxy-bonded plywood remained unchanged at all FA concentrations. Furfurylation improved the resistance of the plywood to delamination, particularly in the 40% and 100% FA treatments. The formation of furfurylated plywood in this study opens up potential opportunities for the use of low-quality veneers from fast growing wood species to replace high-quality veneers from natural forests.

Abstrak: Pemuda merupakan aktor krusial dalam pembangunan. Alat untuk mengukur kemajuan pemuda adalah IPP. Nilai IPP Indonesia khususnya di Jawa Barat masih tergolong rendah sehingga perlu upaya lebih untuk meningkatkan kualitas pemuda melalui kelompok pemuda yang aktif dalam kegiatan positif. Pada sebuah kelompok, terdapat hubungan antaraktor yang membentuk sebuah jaringan komunikasi. Jaringan komunikasi yang baik dalam kelompok pemuda diharapkan dapat mendorong perubahan positif. Oleh karena itu, tujuan utama skripsi ini adalah untuk menganalisis peranan jaringan komunikasi dalam pembangunan kepemudaan. Penelitian ini menggunakan metode sensus kepada 80 responden dengan pendekatan kuantitatif serta menggunakan software UCINET VI. Hasil penelitian menunjukkan bahwa karakteristik pemuda tidak berhubungan dengan jaringan komunikasi. Korelasi terdapat pada frekuensi konflik antarkelompok pemuda dengan sentralitas kedekatan dan kedudukan dalam kelompok dengan sentralitas tingkatan dan kedekatan. Jaringan komunikasi berperan penting dalam pembangunan kepemudaan khususnya dalam meningkatkan motivasi menempuh pendidikan dan kemudahan memperoleh pekerjaan., Youth is a crucial actor in development. The tool for measuring youth progress is the IPP. Indonesia's IPP score, especially in West Java, is still relatively low, so more effort is needed to improve the quality of youth through active youth groups in positive activities. In a group, there are relationships between actors that form a communication network. Good communication networks within youth groups are expected to encourage positive change. Therefore, the main objective of this thesis is to analyze the role of communication networks in youth development. This study used the census method to 80 respondents with a quantitative approach and used the UCINET VI software. The results of the study show that youth characteristics are not related to communication networks. There is a correlation between the frequency of conflicts between youth groups with the centrality of closeness and position in the group with the centrality of degree and closeness. Communication networks play an important role in youth development, especially in increasing motivation to pursue education and ease of getting a job.
