Abstract

Coral reefs are widely recognized as the center of coastal biological activity, coastal protection and geological processes, and also the productive site for fisheries and tourism. By definition, ecological resilience is the ability of a system to undergo, absorb and respond to change and disturbance, while maintaining its functions and controls. The environmental conditions that favor such community resilience may be different from those that favor resistance. From six field components of reef resilience, benthic cover and coral indicators population structure are the most important for reef resilience. This research has been done at 20 sites in northern Aceh reef, i.e. Weh Island (Sabang) and Aceh Besar regency. Benthic coverage data were collected by employing line intercept transects methods, whereas data of indicator coral population structure were collected by employing belt transect. The results show that hard coral ercentage were range from 20.46% - 67.4%. Generally, hard coral cover in areas protected by the Sabang Weh Island management authority was higher than those occurred in open access areas. The resistant corals category includes Porites (massive) and Pavona which are abundant in western Weh Island, while larger coral colonies of resistant category such as Acropora dan Pocillopora, are abundant in eastern Weh Island. If sea surface temperature is increase, west and north parts of the Weh Island will be the most vulnerable areas for coral mass bleaching.

Abstract

This study aims to isolate and identify bioactive compounds contained in the root of tumpunik (Artocarpus rigida BI). The root was firstly extracted using ethanol and then continued with fractionation process using a solvent combination of hexane, chloroform, ethyl acetate, and methanol. The obtained fractionate then was tested its toxicity towards shrimp A Salina larvae. The results show that soxhletation with methanol solvent could produce 36.5 grams of concentrated extract (7.30% of sample weight). Meanwhile, soxhletation using hexane fractionates, chloroform, ethyl acetate, and methanol produces 3.4 grams, 6.9 grams, 9.3 grams, and 16 grams of concentrated extract respectively. The LC50 (ppm) after three-hour toxicity test are 780, 367, 136, and 845 respectively.

Abstract

The number of Diabetes Mellitus(DM) patient in Indonesia tends to increase over the years that put the country in the forth largest number of DM patient in the world. DM becomes one of the main death-causing diseases in Indonesia. Dermatoglyph is a technique that can be employed tohelp diagnose diseases caused by genetic disorder, including early detection for DM. The research aims to reveal the comparison between the DM patients and non DM Patients in terms of finger printpattern, finger ridge number, and ATD angle. The research was undertaken in the Jambi Provincial public hospital by observing 50 DM patients. The collected data were analyzed using Chi Square and t-student tests. The results show that DM patients and non-patients perform difference finger print pattern frequency (X 2:10,8). DM patient tend to have higher arch pattern that that of non-patients.However, the finger ridge number and ATD angle do not indicate any different between DM patients and non-patients.

Abstract

There is a growing concern to use environmentally friendly pesticides including the use of plant-based pesticides. Given that bio pesticides are degraded easily, exploration and scanning to obtain new bio insecticides are continued to be practiced. One of the potential bio insecticides is bulian (Euderoxylon zwagerii). The bulian is a species of hardwood commonly used as construction material by the people of Jambi due to its resistance to termite and mold. The earlier research indicated that the sawdust of bulian is potential to treat Spodoptera litura F., an important crop pest. The purpose of this research is to develop active agents extracted from bulian sawdust to control pest crop especially C. Chalcites. The treatment include the application of bulian extract with concentration of 0,01%, 0,05%, 0,1%, 0,5%, and 1%. The smallest concentration of active extract with the strongest anti-feeding activity will be used as a reference for the following field studies of C. Chalcites. The results showed that, the higher the concentration of n-hexane extract is given, the higher the antifeedant activity of C. Chalcites. The smallest concentration that showed very strong anti-feeding of C. Chalcites is 0.5%

Abstract

This research aims to induce tissue cells of robusta coffee leaves (Coffea canephoravar. Robusta Chev.) for embryogenesis through the addition of growth regulators kinetin and 2,4-D.The growth medium used is a solid Murashige-Skoog medium (MS). The added growth regulators areA = 10-7 Kinetin without 2,4-D, E = 5 x 10-6 M Kinetin and 2.5 x 10-5M 2,4-D; H = 5x10-6M Kinetin and5x10-5 M 2,4-D, I = 7.5 x 10-6M Kinetin and 5x10-5 2,4-D. Explants used were the second leaf from topbranch ortotroph of coffee plants with a size of about 0.5 x 1.0 cm. Observations were made on thepercentage of live explants, explant growth response including the formation of callus, organogenesis,and embryogenesis. The results showed that the planted explants are 100% alive, the growthresponse in the form of direct somatic embryogenesis occurred on the addition of Kinetin 10-7 without2,4-D. Other Treatment, E produced a response in the form of greenish compact callus, while twoother treatments, H and I, form whitish crumb/fragile structured callus. Thus, it was concluded that invitro culture of leaf tissue of Robusta coffee (Coffea canephora var. Robusta Chev.) on Murashige-Skoog (MS) medium with the addition of kinetin growth regulators and 2,4-D at different concentrationsproduce higher different growth rate. Response of growth that occurs is in the form of direct somaticembryogenesis, compact and crumb/fragile structured callus.

Abstract

Preferensi makanan larva Papilio polytes L. pada empat tanaman inang (Citrusaurantifolia (Chrism.) Swing, Citrus reticulata Blanco, Citrus hystrix DC, dan Murraya koenigii L.) telahdiselidiki di laboratorium. Preferensi makan instar pertama P. polytes berbeda nyata (p<0,05) untuktanaman inang di semua kombinasi daun tanaman inang yang diuji, kecuali kombinasi C.hystrix danC. reticulata. Selanjutnya, preferensi makan larva instar ketiga terhadap tiga daun tiga spesiesspesies jeruk kecuali M. koenigii, sedangkan larva instar ketiga tidak menunjukkan preferensi makanyang signifikan diantara Citrus spp. Pada larva instar kelima, tidak menunjukkan adanya preferensimakan pada daun dari semua spesies jeruk, tapi konsisten konsumsi terhdap M. koenigiidibandingkan Citrus spp. dalam berbagai kombinasi yang diuji. Larva P. polytes instar pertama daninstar ketiga lebih selektif dalam hal makan daripada instar kelima. Kandungan nitrogen dalam daunkeempat tanaman inang berbeda nyata (p <0,01), dengan C. reticulata adalah yang tertinggi (4,52%),sedangkan kadar air daun berbeda nyata antara M. koeniggi (71,72%) dibandingkan ketiga spesiesCitrus (76,38-79,12%), tetapi tidak berbeda nyata diantara ketiga spesies jeruk itu sendiri.

Abstract

Patikan kerbau (Eupobia hirta L.) contains some anti-diarrheal compounds or containanti-bacterial substances which are alkaloids, flavonoids and tannins. This study aims to determine theeffect of extract of patikan kerbau on the growth of bacteria causing diarrhea (E.coli). This researchtests phytochemical properties and examines inhibition zone (hallow zone). The design used wasCompletely Randomized Design (CRD) with six treatment of patikan kerbau extract (0 ppm, 1500 ppm,1750 ppm, 2000 ppm, 2250 ppm and 2500 ppm) and four replications. Data were analyzed by usingANOVA and if there is a significant difference, the test will be followed by a DNMRT test at 5%significance level. Phytochemical test was based on the formed color intensity. The results showedthat - average inhibition zone diameter on treatment 2500 ppm with a diameter of 10.75 mm was notsignificantly different from 2250 ppm treatment with diameter of 9.75 mm. However, it wassignificantly different with treatments of 2000 ppm, 1750 ppm, 1500 ppm and control. The controlgroup (0 ppm) with a diameter of 6 mm (no inhibition zone formed) was significantly different fromother treatments. Phytochemical test showed that the active compound contained in patikan kerbauare alkaloids, flavonoids and tannins. These compounds have anti-bacterial property and can be usedas an anti-bacteria.
