PEMANFAATAN EKSTRAK AKAR TUBA (Derris elliptica B.) DALAM MENGENDALIKAN KECOAK JERMAN (Blattella germanica L.)

German cockroach (Blattella germanica L.) are insect pests and vectors of various diseases, so their populations need to be controlled using biopesticides that are easily biodegradable and do not have a negative impact on the environment. The tuba plant (Derris elliptica B.) is a plant that is used as a natural pesticide, especially in its roots. The purpose of this study was to determine the toxicity of aqueous extracts and methanolic extracts of tuba roots based on the LC50 and LT50 values from probit analysis and to compare their effectiveness using the One Way ANOVA test to controlling german cockroach using the bait method with varying concentrations of treatment for 10 individual cockroach with four replications. The LC50-72 hours of tuba root aqueous extract and methanol extract using the feed method were 62.446% (v/v) and 71.857% (w/v). The LT50-60% value of the feed method water extract was 57.926 hours, while the LT50-80% value of the feed method methanol extract was 60.659 hours. The aqueous extract of tuba roots was more effective in controlling german cockroaches than the methanol extract of tuba roots using the bait method

NEMATODA PARASIT GASTROINTESTINAL Pongo pygmaeus wurmbii (Tiedemann, 1880) DI STASIUN RISET CABANG PANTI, TAMAN NASIONAL GUNUNG PALUNG

The orangutans are one of the great apes whose existence is threatened with extinction. Infection from gastrointestinal nematodes is one of the inhibiting factors for the survival of orangutans. The study aims to find nematode parasites infection in orangutans. Observations were made by 27 fecal samples from 13 individual orangutans. All samples were analysed with qualitative methods (native, flotation, and sedimentation). The parasitic nematodes discovered were Ancylostomatidae (hookworm) (61%), Strongyloides stercoralis (61%), Mammomonogamus sp. (38%), Ternidens sp. (23%), Ascaris lumbricoides (23%), Trichuris trichiura (15%), and Trichostrongylus sp. (8%). This is the first study to identify Mammomonogamus sp. and Ternidens sp. in orangutan fecal samples from Gunung Palung National Park. Only about 4% of the 300 orangutans in Cabang Panti are known to be infected with gastrointestinal parasitic nematodes

KUALITAS HABITAT KEPITING BAKAU (Scylla serrata-Forsskål) DI PERAIRAN PANTAI DESA SENGKUBANG KECAMATAN MEMPAWAH HILIR KABUPATEN MEMPAWAH

Mangrove crab (Scylla serrata) is one of the fishery resources that has economic value. The fulfillment of market needs that are still dependent on nature encourages efforts in the cultivation of mangrove crabs (Scylla serrata). Sengkubang Village has a mangrove area which is the habitat of mangrove crabs that have the potential to be used as cultivated land, but data related to habitat parameters and quality are not yet available. The purpose of this study was to determine the characteristics and quality of mangrove crab habitat (Scylla serrata) in the coastal waters of Sengkubang Village, Mempawah Hilir District, Mempawah Regency. The research method used is to measure water quality including temperature, salinity, water pH, substrate pH, DO, tidal waterlogging, substrate texture, vegetation type, and vegetation density. Crab fishing is carried out by free sampling and using traditional traps (bubu). The research data was compared with habitat quality score data based on the Mangrove Crab Habitat Quality Index. The results showed that the quality of the mangrove crab habitat of Scylla serrata in the coastal waters of Sengkubang village, Mempawah Hilir District, Mempawah Regency is classified as moderate with a total value of 58 so that it is quite supportive for the growth and development of mangrove crabs

Insect is a dominant group of animals on earth with the most common number of species and individuals compared to other animal groups. Research about insect diversity in the forest area of IUPHHK-HTI PT. Muara Sungai Landak in swamp peat forest should be done to know its role. The research was aimed to determine the species of insects and to know the effect of environmental factors to insects in the area of PT. Muara Sungai Landak. Insects collected from five different age groups of plants with trapping methods using pit fall trap, yellow pan trap, and light trap. Insects found in the area of PT. Muara Sungai Landak counted as many as to 282 individuals consisting of 18 species, 15 families, and 6 orders. The most widely found number of individuals was the species of Condylostylus longicornis. The highest diversity value was found in the two-year plant age group with a diversity value of H' = 1,69654, while the lowest diversity value was found in the three-year plant age group with the value H ' = 1,2075

JENIS-JENIS SEMUT ARBOREAL (HYMENOPTERA: FORMICIDAE) DI KAWASAN KAMPUS UNIVERSITAS TANJUNGPURA DENGAN TIGA METODE KOLEKSI

Ants as insects occupy various habitats and ecological niches. Universitas Tanjungpura is an area with variable vegetation physiognomies that has the potential to have a lot of ant microhabitat. This study aims to determine the most effective method for collecting arboreal ants (Hymenoptera: Formicidae) found in the campus area of Universitas Tanjungpura. The study was conducted from August 2018 to February 2019 at ten locations  based on their environmental condition. Ants were collected in three different methods: hand collecting, bait traps, and yellow pan traps. There were 39 species of Formicidae collectedfromall locations. These results were obtained by hand collecting (32 species), bait traps (32 species), and yellow pan traps (4 species). Hand collecting and bait traps are the most effective method for collecting arboreal ants in Universitas Tanjungpura

Efikasi Asap Cair dari Kayu Bengkirai terhadap Phytophthora Citrophthora

Bengkirai is one of kind of woods usually used for furnitures and produces lots of woodcuts. This woodcut become the raw material for liquid smoke. The efficacy of liquid smoke produced from bengkirai wood against Phytophthora citrophthora was evaluated. The aim of this research was to evaluate antimicrobial properties of liquid smoke from bengkirai wood against P. citrophthora. Three kinds of liquid smoke were used in three temperatures i.e., 350, 400 and 450ºC. Efficacy of liquid smoke from bengkirai wood for antimicrobial used PDA medium. Simple linear regression was used to measured the effect of liquid smoke concentration to inhibition of P. citrophthora growth. The relationship between the concentration of liquid smoke (X) and inhibition of fungal growth, P. citrophthora (Y) at 350, 400, and 450ºC were Y = 24.51 + 5.27X (r2 = 0.98), Y = 54.31 + 5.53X (r2 = 0,92), and Y = 51.32 + 16.87X (r2 = 0.80). The results showed that the concentration of liquid smoke was significantly different for inhibition of P. citrophthora growth. The higher the concentration the higher the inhibition of microbial growth. The highest inhibition was on liquid smoke of bengkirai wood with temperature pyrolysis of 450ºC and concentration of liquid smoke of 1% with average value of 100%. IntisariBengkirai merupakan bahan baku pembuatan furniture yang banyak menghasilkan limbah potongan kayu. Limbah potongan kayu ini dapat dijadikan sebagai sumber pembuatan asap cair. Penelitian tentang efikasi asap cair dari kayu bengkirai terhadap Phytophthora citrophthora telah dilakukan. Penelitian ini bertujuan untuk mengevaluasi sifat antimikrobia asap cair kayu bengkirai dalam menghambat pertumbuhan P. citrophthora secara in vitro. Tiga jenis asap cair kayu bengkirai hasil pirolisis pada suhu 350, 400, dan 450ºC. Medium PDA digunakan untuk efikasi asap cair kayu bengkirai terhadap pertumbuhan P. citrophthora. Analisis regresi linier sederhana digunakan untuk mengevaluasi pengaruh konsentrasi terhadap daya hambat pertumbuhan P. citrophthora. Konsentrasi asap cair kayu bengkirai yang digunakan adalah 0; 0,5; 1,0; 1,5 dan 2,0 %, v/v. Hasil penelitian menunjukkan bahwa hubungan antara konsentrasi asap cair (X) dan daya hambat pertumbuhan P. citrophthora (Y) pada suhu pirolisis asap cair 350, 400, dan 450ºC berturut-turut adalah Y = 24,51 + 5,27X (r2 = 0,98), Y = 54,31 + 5,53X (r2 = 0,92), dan Y = 51,32 + 16,87X (r2 = 0,80). Makin tinggi konsentrasi asap cair kayu bengkirai makin tinggi daya hambat terhadap pertumbuhan P. citrophthora. Daya hambat pertumbuhan P. citrophthora tertinggi (100 %) pada perlakuan asap cair kayu bengkirai yang diproduksi pada suhu pirolisis 450ºC dan konsentrasi 1 %
