Abstract

Penelitian ini bertujuanuntuk mempelajari penularan penyakit CVPD melaluivektor Diaphorina citri stadia imago dan nimfa pada jeruk Siem dan Rough Lemon. Percobaan dilaksanakan dengan menggunakan Rancangan Acak Lengkap pola faktorial dua faktor.Faktor Kultivar Jeruk (Rough Lemon, dan Siem) diletakkan sebagai faktor pertama, sedangkan fakor stadia vektor (Nimfa, dan Imago) sebagai faktor kedua. Empat kombinasi perlakukan masing-masing diulang 5 kali.Tiap perlakuan terdiri dari 2 pot tanaman percobaan.Data respons tanaman terhadap penyakit CVPD yang diinokulast melalul vektor D.citri berbeda stadia diperoleh dengan menghitung:1) masa inkubasi yang diperoleh dengan cara mengamati lamanya waktu yang diperlukan tanaman sejak diinokulasi patogen sampai timbulnya gejala pertama;2) persentase daun klorosis yang diperoleh melalui pengamatan daun sampel yang diambil secara acak dan dihitung jumlah daun yang klorosis dari jumlah daun tanaman sampel, 3) persentase cabang yang bergejala, diperoleh dengan menghitung jumlah cabang yang bergejala dari jumlah cabang seluruhnya per tanaman tiap perlakuan.Hasil penelitian menunjukkan bahwa masa inkubasi penyakit CVPD, persentase daun klorosis, dan persentase daun bergejala lebih cepat dan lebih tinggi pada jeruk Siem dibandingkan dengan pada jeruk Rough Lemon, baik yang ditulari melalui inokulasi dengan D. citri stadia imago maupun stadia nimfa. Tetapi penularan melalui inokulasi D. citri pada stadio imago lebih cepat memunculkan masa inkubasi, persentase daun, klorosis, dan persentase cabang bergejala lebih tinggi dibandingkan dengan stadia nimfa. Jeruk siem dan penularan penyakit CVPD melalui D. citri stadia nimfa dapat dijadikan cara deteksi dini penyakit CVPD pada jeruk

Abstract

Beef is one of the Indonesian favorite foods and provides protein needed for human body’s health and growth. Rumah Pemotongan Hewan (RPH) Jambi is a slaughtering house that provides and distributes beef to traditional markets throughout Jambi City. Therefore, it is very essential to assure safetyof every piece of beef produced by the RPH. This research was undertaken in Biology UP-MIPA Laboratory, University of Jambi, from December 2009 to January 2010. The beef samples were collected from the Jambi RPH. This research employs the Most Probable Number (MPN) method, by observing the growth of Escherichia coli on Endo Agar media, starting from presumptive test until confirmative test. The experiment used 5-5-5 series reaction tubes, including the Durham fermentation tube. The results show that beef produced by the JAMBI RPH is 100% safe to be consumed. The number of Escherichia coli in the fresh beef is still below the maximum threshold level, which is 5 X 101MPN/100 ml

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

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.
