Abstract

Many favorable properties of wood are available in almost all parts of the world, easily obtained in different shapes and sizes, relatively easy to process, as well as very decorative appearance. However, wood also has a weakness that could be damaged by a variety of factors either biological, physical, mechanical or chemical. In reality, the main factors causing damage to the wood are fungi, bacteria, insects and marine animals (marine borer). The organisms might damage the wood because they make as a shelter or as feed. Therefore, there should be conducted wood preservation to overcome the unfavorable properties of the woods. Wood preservation aims to extend the use of low-class durability of timber species such as Bayur (Pterospermum sp), Durian (Durio zibethinus) and Benuang (Octomeles sumatrana Miq). This study aimed at determining the effectiveness of a natural preservative tembelekan (Lantana camara L). The research was conducted at the Forestry Sciences Laboratory, Department of Forestry, Forestry Faculty, Tadulako University and Talise Mantikulore Sub-district, started from May to July 2013. The study was designed with the method of completely randomized design (CRD) with three wood species treatment, namely bayur, durian and benuang. Each was preserved with a natural preservatives of tembelekan extract with a concentraation of 13,04%. There were 10 samples of each type of wood, consisting of 5 test samples preserved and 5 controls (without preserrvatives). There were 30 test samples. The parameters observed were preservative effectiveness of the sample weight after feeding on soil termites. The study shows that highest natural preservative effectiveness on benuang wood was preserved with the sample weight loss of 2,25% and the lowest on bayur wood was preserved with the sample weight loss of 3,47% when they were compared with the control sample (without preservative). Using tembelekan extract might increase wood resistance to soil termite attacks. Keywords: Captotermes sp, Durio zibethinus, Lantana camara L, Octomeles sumatrana Miq, tembelekan.

Abstract

Bunga kelapa sawit bersifat monoceus. Penyerbukannya dapat terjadi oleh bantuan serangga penyerbuk. Kumbang Elaeidobius kamerunicus adalah penyerbuk spesialis, yang bersama dengan jenis-jenis serangga lain melakukan penyerbukan kelapa sawit. Pengelolaan penyerbukan kelapa sawit di setiap perkebunan berbeda karena serangga penyerbuknya pun berbeda sehingga perlu disesuaikan dengan kondisi lingkungan masing-masing. Tidak ada publikasi tentang serangga penyerbuk lokal pada kelapa sawit di Indonesia selain oleh kumbang E. kamerunicus. Pada penelitian ini ditemukan serangga penyerbuk kelapa sawit lainnya, disamping E. kamerunicus, yaitu enam jenis lebah yang terdiri dari Apis florea, A. cerana, A. koschevnicovi, Trigona laeviceps, T. melina, dan T. itama yang mengunjungi bunga jantan anthesis dan betina receptive. Berdasarkan analisa ukuran dan perilaku kunjungan pada bunga betina disimpulkan bahwa hanya tiga jenis A. florea, Trigona laeviceps, dan T. melina yang mempunyai potensi tinggi sebagai penyerbuk bunga kelapa sawit pada bagian permukaan bunga. Sedangkan kumbang E. kamerunicus lebih berperan sebagai penyerbuk bagian dalam dari perbungaan. Populasi kumbang E. kamerunicus per hektar relatif rendah yang menyebabkan sebanyak 35,1% buah kelapa sawit yang tidak berkembang. Pemanfaatan kumbang E. kamerunicus untuk penyerbukan buatan telah dilakukan oleh petani kelapa sawit, namun dilakukan dengan cara yang menimbulkan banyak kematian pada kumbang muda.

Abstract

Elaeidobius kamerunicus (kumbang sawit) adalah penyerbuk utama dari bunga kelapa sawit. Kondisi populasi kumbang sawit dalam suatu lingkungan perkebunan kelapa sawit sangat menentukan tingkat keberhasilan dari produksi buah. Faktor-faktor yang mempengaruhi kondisi populasi kumbang sawit, selain dari faktor internal, juga dari varietas tanaman, pola cocok tanam, pemupukan, dan pengendalian hama terpadu serta kondisi lingkungan fisik dan biotik. Lingkungan fisik salah satunya adalah iklim, sedangkan lingkungan biotik adalah musuh alami yaitu predator dan parasitoid. Penelitian tentang peran lingkungan biotik terhadap populasi kumbang sawit dilakukan pada musim hujan dan musim kemarau di perkebunan kelapa sawit di Kabupaten Penajam Paser Utara, Kalimantan Timur. Ditemukan sebanyak 7 jenis predator yang terdiri dari: 2 jenis burung, 5 jenis serangga (semut Odontoponera denticulata (Formicidae), cecopet Chelisoches morio (Chelisochidae), kepik Velinus nigrigenu (Reduviidae), dan tawon Vespa affinis, V. bellicosa (Vespidae)). Sebanyak 10 jenis tawon parasitoid juga ditemukan (Evaniidae 1 jenis, Braconidae 2, Scelionidae 2, Eulophidae 2, Chalcididae 1, Mymaridae 1, dan Ormyridae 1). Namun, potensi sebagai musuh alami penyerbuk kelapa sawit masih memerlukan penelitian lebih lanjut. Dipertelakan ekologi perilaku dari setiap jenis musuh alam dari kumbang sawit sehingga diketahui tingkat potensinya sebagai pengontrol populasi kumbang sawit.
