Judul: Relationship between Growth Site Factors and Silvicultural Treatment on Productivity of Kayu Bawang (Dysoxylum mollissimum Blume) in People’s Forest of Bengkulu.
Abstrak: Kayu bawang (Dysoxylum mollissimum Blume) is a local species which is considered as superior in Bengkulu and is used as construction wood. Wood of this species is resistant toward termite attack, has aroma like onion, and is bitter. Kayu bawang has good quality wood, belongs to resistance level B, or resistance level which ranges from fairly resistant to resistant toward termite attack. Kayu bawang has straight stem and is categorized as fast growing species. Planting of kayu bawang has varied productivity. This research was aimed at determining the relationship between growth site factors and silvicultural treatments on productivity of kayu bawang. This study conducted on communities forest in North and Central Bengkulu District, Province of Bengkulu. In this research, principal component analysis was used and silvicultural treatment was analyzed descriptively in qualitative manner. Research results showed that growth site factors which were negatively correlated with productivity of kayu bawang in the research location were slope, altitude, and percentage of light intensity. The optimum planting of kayu bawang in the research location was at slopes ranging between 0-20%, altitude ranging between 23-65 m asl, and percentage of light intensity ranging between 9-19%. Productivity of kayu bawang at poor condition of growth site could be improved through appropriate silvicultural treatment. Silvicultural treatments which had been practiced by the people were still not good yet. Planting stocks being planted were usually originated from natural regeneration. Planting was done in irregular manner (random). Activities of soil tillage, weeding, and prunning were seldom practiced. Besides that, activities of replanting of failure, fertilizer application and thinning were never conducted.

Judul: Model Pertumbuhan Tegakan Kayu Bawang (Protium javanicum Burm F.) pada Berbagai Pola Tanam dan Kerapatan Tegakan
Abstrak: Hutan rakyat merupakan salah satu bentuk hutan yang ditanam di tanah milik masyarakat. Kontribusi hutan rakyat dalam memenuhi kebutuhan kayu akan nyata apabila dikelola dengan baik dan berkembang di masyarakat. Salah satu contoh hutan rakyat yang cukup berkembang di masyarakat adalah hutan rakyat kayu bawang (Protium javanicum Burm F.) di Propinsi Bengkulu yang telah ditetapkan sebagai jenis andalan di daerah ini. Kayu bawang merupakan jenis lokal yang mempunyai pertumbuhan cepat (daur 10-15 tahun) dan kualitas kayu yang baik, terutama untuk kayu pertukangan. Pengembangan kayu bawang dalam bentuk hutan rakyat dimulai pada tahun 1990-an dengan teknik budidaya yang sederhana. Penanaman dilakukan dengan pola tumpangsari atau pola agroforestry. Pada pola tumpangsari, kayu bawang ditanam dengan jenis tanaman semusim seperti cabe dan kacang tanah, namun pola ini tidak banyak dijumpai. Sedangkan pola agroforestry dapat dijumpai dalam bentuk kombinasi antara kayu bawang dan kopi atau dalam bentuk kombinasi multijenis dengan kopi, karet, jengkol dan kayu manis.
