Abstract

Until now, the supply of the seed sources still rely on seeds or germs. Meanwhie, the certain wood species, the production of seeds are insufficient and the handling is quite difficult. Consequently, when seedling, their germination capacities and growth percentages are very low. Providing seed source through shoot cuttings which if it is planted in advantegous condition for regeneration, it will grow and develop into fast growing species as well as good quality species. Supplying of plant growth regulator is expectedly able to affect the plant growth when given according to the plant needs. This research aimed to determine the concetration level of growth reglator IBA (Indole Butyric Acid) for the growth of shoot cuttings of agarwood Gyrinops verstegii. The method used in this research is experiment with completely-randomized design (CRD). Results showed that the concentration level of IBA affected the growth of callus, roots and shoots. IBA treatment at the concentration of 300 ppm showed the best response to the cutting life, growed earlier, the number and the length of shoot are greater. However, in the root zone, the treatment without IBA hormone provided better response which is showed by the number and the length of root.Key words: Gyrinops verstegii, Indole Butyric Acid, growth response

Abstract

Tujuan dari penelitian ini adalah untuk mengetahui pengaruh media kecambah tanah yang dicampur arang limbah gergaji dan arang sekam dalam perkecambahan benih Aquilaria malaccensis. Metode yang digunakan dalam penelitian ini adalah eksperimen yang dirancang dengan Rancangan Acak Lengkap (RAL). Data dianalisis dengan Analisi Ragam (Anova) untuk mengetahui pengaruh media terhadap daya kecambah. Untuk mengetahui mengetahui media perkecambahan mana yang memberikan persen dan waktu perkecambahan yang baik digunakan analisis HSD (TUKEY). Hasil penelitian menunjukkan bahwa persen dan waktu perkecambahan benih A. malaccensis yang baik adalah pada media kecambah tanah yang dicampur arang gergaji dan sekam. Persen perkecambahan pada media ini mencapai 79,33% dengan waktu perkecambahan 20 hari.

Abstract

Tujuan dari penelitian ini adalah untuk mengetahui respon pertumbuhan semai gaharu (Aquilaria malaccensis) terhadap pemberian pupuk organik melalui penggunaan metode eksperimen rancangan percobaan lengkap (RAL) dengan total 180 unit percobaan. Hasil penelitian respon pertumbuhan semai gaharu menunjukkan tidak ada perbedaan yang nyata antara ketiga perlakuan yang diberikan terhadap pertambahan tinggi semai gaharu dengan nilai F hitung 2,196 lebih besar dari pada signifikannya yaitu 0,192. Rata-rata pertumbuhan diameter tertinggi dimiliki oleh perlakuan kontrol yaitu 0,037 cm sedangkan perlakuan media campuran pupuk kandang dan top soil dan media campuran pupuk kandang, EM4+ dan top soil memiliki nilai rata-rata pertumbuhan yaitu 0,09 dan 0,08 cm. Hasil penelitian menunjukkan bahwa tidak ada perbedaan yang nyata antara tinggi, diameter dan percabangan tanaman pada ketiga perlakuan yang diberikan.

Abstract

Sago palm (Metroxylon sagu) plays a vital role in the Papuan indigenous community’s social, economic, and cultural life. It is a source of staple food, household income, and embedded cultural values. This research aimed to determine the extent of sago palm habitat spread using spatial data. The classification method and multispectral imaging were used by employing satellite imagery (Landsat 8 and Quick Bird) and field surveys. The sago forest coverage in Yapen islands was 87.73%, located between 9–50 masl, covering 9,456.26 ha. The results revealed that 43.53% of the habitat lies in the inclination of 2–8% (extreme gentle slope), covering 4,692.45 ha. Sago forest was found in a gleysol soil type with precipitation of 3,000-3,100 mm. The sago forest distances of 0–250 m and 251–500 m to the coastline showed that the habitat covers an area of 153.87 ha and 368.19 ha. The preferable area in this category is Raimbawi Subdistrict, followed by Kosiwo, and the less suitable area, or the marginal land, is in Windesi Subdistrict.

Abstract

This community service program aims to improve the capacity of local Tehit farmers in Southwest Papua to implement efficient and environmentally friendly seeding techniques. The program was implemented through a participatory approach, including outreach, training, and direct field mentoring. The results showed active community participation in all stages, as well as a 65% increase in knowledge, from 25% before training to 90% after mentoring. This improvement directly impacted seed germination success, which increased from an average of 60–65% to 88–92%. Furthermore, the community began using nursery containers with pot trays, contributing to reduced plastic waste and increased environmental awareness. Overall, the program successfully strengthened farmer capacity, increased crop productivity, and supported sustainable agricultural practices. This program directly contributes to the achievement of the Sustainable Development Goals (SDGs), particularly SDG 1 (No Poverty), SDG 2 (Zero Hunger), SDG 12 (Responsible Consumption and Production), and SDG 15 (Life on Land).
