Abstract

S Sengon (Falcataria moluccana Miq.) is a pioneer tree species that is widely developed in industrial plantation forests and community forests because of its fast growing species. The properties of sengon seeds which are classified as orthodox can decrease their viability and vigor during storage. The colchicine hormone is expected to increase the acceleration of plant growth so that it can increase the success of sengon seed growth. The aim of this research was to see the effect of colchicine treatment on the accelerated growth of sengon seeds. This research was carried out using a Completely Randomized Design (CRD) with one factor, namely colchicine concentration. The concentrations used are: 0 (control), 0.5 ppm, 1.0 ppm, 1.5 ppm, 2.0 ppm. The effect of the treatment was seen through variance testing using SAS 9.0 portable software. The variance results showed that soaking in colchicine solution had a very significant effect on the maximum growth potential, germination capacity and germination value, while the colchicine solution soaking treatment had no real effect on growth speed.

Abstract

Compound N-phenetyl 4-O-asetil ferulamide had been synthesized from ferulic acid and phenetylamine through esterification and indirect amidation method. Esterification reaction of ferulic acid with anhydride acetate was done in pyridine solvent at room temperature. Indirect amidation was perform by chlorination using tionyl chloride in benzene solvent at 70°C and continued by amidation with phenetylamine, catalyzed by pyridine in dichloromethane solvent at room temperature. the compound obtained is brown yellowish crystal with melting point 118-120°C. The rendemen of target compound is 53.81%.

Abstract

This training was designed to introduce ecoprint techniques to members of the Women's Dharma Association of the West Papua Provincial Forestry Service, emphasizing its potential as a community-based business opportunity. The activity utilized natural materials readily available in the surrounding environment, such as butterfly pea leaves and flowers, teak leaves, and other local foliage. The training was conducted in stages, beginning with an introduction to the basic concepts of eco-printing, followed by hands-on practice using two main techniques: pounding and steaming. These techniques were applied to cloth tote bags and ceramic mugs. The results showed that participants demonstrated a higher level of proficiency in producing eco prints using the steaming technique compared to the pounding method.

Abstract

Keterbatasan fasilitas laboratorium konvensional mendorong perlunya alternatif inovatif dalam pembelajaran praktikum kimia. Salah satu solusi yang potensial adalah penggunaan Chemistry Laboratory Application berbasis digital. Penelitian ini bertujuan mengevaluasi efektivitas penggunaan aplikasi Irydium Chemistry Lab dalam praktikum kimia dasar pada mahasiswa program studi pendidikan kimia. Metode yang digunakan adalah kualitatif deskriptif melalui wawancara, survei, dan observasi. Hasil menunjukkan bahwa meskipun aplikasi nonpraktikum telah umum digunakan, namun ternyata masih banyak mahasiswa yang baru mengenal aplikasi praktikum virtual. Mereka menilai Irydium mudah diinstal, ramah pengguna, dan membantu dalam memahami konsep dasar kimia. Temuan ini memberikan wawasan penting bagi pendidik dan pemangku kebijakan untuk mengoptimalkan penggunaan laboratorium virtual, baik di tingkat perguruan tinggi maupun pendidikan menengah melalui kegiatan PPL dan praktik mengajar di masa depan.
