Abstract

Indonesia merupakan Negara dengan tingkat pertumbuhan penduduk yang tinggi. hal tersebut berdampak pada tingginya permintaan akan kebutuhan minyak nasional, yang diperdiksi hanya mampu memenuhi kebutuhan energi selama 11 tahun kedepan. Salah satu solusi untuk mengatasi krisis energi yaitu dengan memanfaatkan sumber energi alternatif seperti bioetanol. Selama ini, pengembangan bioetanol berasal dari bahan berpati dan bergula seperti tebu, ubi dan jagung. Padahal bahan-bahan tersebut merupakan sumber pangan yang cukup komersial, sehingga pengembangan bioetanol dari bahan tersebut dapat menimbulkan masalah yang krusial terhadap pemenuhan kebutuhan pangan masyarakat. Oleh karena itu, perlu adanya pertimbangan dalam pemilihan sumber bioetanol yang ramah lingkungan seperti pemanfaatan gulma eceng gondok. Pengembangan bioetanol dari gulma eceng gondok tersebut melalui 4 tahapan yaitu tahan pre-hidrolisis treatment dengan asam sulfat 2%, hidrolisis dengan larutan buffer pH 7, fermentasi dengan memanfaatkan peran mikroba dalam sistem pencernaan rayap Macrotermes gilvus untuk mendegradasi selulosa dan destilasi untuk memurnikan bioetanol yang diperoleh. Penelitian ini merupakan penelitian eksperimental dengan 5 kali ulangan. Variabel penelitian ini yaitu konsentrasi bioaktivator (0%, 10%, 20%, 30%, 40% dan 50%) dan lama waktu fermentasi yaitu 48 jam dan 96 jam. Hasil yang diperoleh pada penelitian menunjukkan sampel dengan lama waktu fermentasi 48 jam dan ditambahkan bioaktivator 50% memiliki kadar alkohol yang paling tinggi yaitu 2,2%.

Abstract

Subterranean termite, Macrotermes, play important role on plant nutritive cycles through disintegration and decomposition of organic matter processes.  In the other hand, subterranean termite can cause wooden damage in the nature and human dormitory as well. Therefore, Macrotermes are potential pest and need to be controlled.  Effective pest-control of subterranean termite can be made when their species status and distribution are well known. This research is aimed to identify the status of species and the dispersal of Macrotermes at their natural habitat in order to explore natural bio-resources richness and as an effort towards effective pest-control due to increasing risk of attack.  Survey method was used termite samples were collected at four different locations which are defined by global positioning system (GPS).  Nest classification is according to Meyer et al. (2003). The nest mapping is based on the elevations of their natural habitat in Gunung Halimun Salak National Park (900-1000 asl), and (600-700 asl), Yanlappa sanctuary (200-300 asl), and Ujung Kulon Nasional Park (0-100 asl). Phylogenetic relationships analysis showed that subterranean termite Macrotermes in the natural forest community are belongs to one big group Macrotermes gilvus Hagen. Based on nest size, the colony of Macrotermes can be classified into three different sizes: large, medium, and small nest.  Large and medium nest can be found in large amount in Yanlappa sanctuary (15 and 23 colonies, respectively) and the majority of small nest occurred in Gunung Halimun Salak National Park at 900 asl (78 colonies). Temperature and humidity is the most environmental factor that can influence on termite and other factor is rain fall, soil structure, and plant vegetation.   Keywords:  Distribution, identify, Macrotermes gilvus Hagen, nest

Abstract

Subterranean termite Coptotermes spp. has been known as the most economically important structural pest in Indonesia. Due to morphological ambiguity, traditional identification of Coptotermes spp. has always been difficult and unreliable.  Through molecular diagnostic method, a study was conducted to determine genetic variation of Coptotermes spp. occurring in Java Island.  Termite specimens were collected from Banten 1, Banten 2, DKI 1, DKI 2, Jabar 1, Jabar 2, Jateng 1, Jateng 2, Yogya 1, Yogya 2, Jatim 1, and Jatim 2.  The method for identification was PCR-Restriction Fragment Length Polymorphism (PCR-RFLP) analysis using four restriction enzymes each of which was applied to CO II amplicon for all the Coptotermes spp. being analyzed.  The results showed the existence of two species of Coptotermes in Java which are different from both Coptotermes gestroi and Coptotermes formosanus.
