Publisher : Biologi UNJ Press

Various studies had been conducted regarding the effect of curcumin on AD patients, thus, many of the studies had suggested that curcumin had the potential to prevent and treat AD through several molecular mechanisms including act as anti-inflammatory, anti-oxidant, binding the AÎ² plaques, metal chelation, and lowering cholesterol level. One of the prominent characteristics of this neurodegenerative disease is shown by the presence of beta amyloids plaques (AÎ²) and inflammation inside the patientâ€™s brains; and as mention above curcumin had shown its capabilities in inhibiting the AÎ² plaques and act as an anti-inflammation agent.

The main problem in tropical poultry farming that often happens is a high mortality rate. Deaths occurrance mostly by heat stress, a condition which is caused by high temperature ( > 28 Â° C). Prolonged heat stress was given to 24 quails grouped in four groups: A (39 Â° C), B (41 Â° C), C (43 Â° C) and D (45 Â° C). Provision of heat stress was done when the quails were 2 days old. Blood sampling was performed at the age of 6 weeks. Overall, there was an increase in the number of white blood cell, heterophile, eosinophil, monocyte, the ratio between heterophyll and lymphocyte and malondialdehyde (MDA) levels in all treatment groups. While the number of lymphocytes decreased in all treatment groups. Basophils had a significant increase in group C, but there was a decrease in group B and D decreased from control. This indicates that maintenance above temperature > 25 Â° C can cause oxidative stress due to heat stress in quail.

Crested serpent eagle (Spilornis cheela) is a bird of prey with distinctive of uniue vocal. Based on several studies mentioned that there are differences in vocalization at the level of subspecies and is often used to study the role vocalization defining the subspecies in taxonomy. This research aimed to determine the role variation of vocalization pattern in taxonomy on subspecies eagle. The research was conducted from May to September 2017 at Kamojang Eagle Conservation Center. The method used is descriptive method with continuous sampling technique. The samples was an adult eagle from three subspecies serpent eagle. The location of observation determined by purposive sampling with the provisions listening post is less than 5 meters until 30 meters. The data is collected at 7 am to 5 pm. Data were analyzed using sound analysis software. The data taken are fundamental frequency, maximum frequency (MinF), minimum frequency (MinF) and duration. Differences between subspecies were analyzed using Kruskal Wallis and Mann-Whitney U statistical test with SPSS 17.0. The result of the research is The vocalizations can be utilized in the subspecies eagle taxonomy of the species to complement the morphological data, marked by significantly different results on each parameter of vocalization between (Spilornis cheela malayensis) and (Spilornis cheela natunensis). MaxF significantly different in (Spilornis cheela malayensis) and (Spilornis cheela bido), (Spilornis cheela natunensis) and (Spilornis cheela bido).

The composition of feed can improve and optimize the fermentation in sheep rumen. The purpose of this study is to determine the effect of probiotic and cellobiose to rumen fermentation of sheep. Four adult (weight Â±13.5 kg) rumen fistulae sheep were used. The fed given were King grass (Pennisetum purpureum), rice bran and soybean meal that are protected by formaldehyde 0.3% as base feed. Fed treatment were probiotics (0,5% and 1%) and cellobiose (1 ppm and 3 ppm). Parameters measured were pH, N-NH3 and VFA concentration of rumen fluid at 0, 2, 6, 12, and 24 hours after feeding with Completely Randomized Design Factorials 4x5 and continued with Duncan test (Î±=0,05). The ruminal pH range for all treatments between 6.27 - 6.89. The maximum N-NH3 concentration value has been reached at 2 hours after feeding 12.25-18.75 mM. At 0 hours, the total VFA concentration was at an average value of 294.91 mg% and then increased at 2-6 hours reaching its maximum value in the range 661.97-767.70 mg% (p<0.05). The addition of probiotics and cellobiose can optimize rumen fermentation of sheep.

UJI KETAHANAN NILAM TERHADAP Synchytrium pogostemonis PENYEBAB PENYAKIT BUDOK DAN POTENSI PENGENDALIANNYA DENGAN PESTISIDA NABATI Tri Yuliyanti; Sri Yuni Hartati; Reni Indrayanti

Nilam (Pogostemon cablin Benth.) merupakan tanaman semak penghasil minyak atsiri yang memiliki nilai ekonomi yang tinggi. Budidaya tanaman nilam memiliki kendala yaitu adanya serangan kapang Synchytrium pogostemonis penyebab penyakit budok. Tujuan dari penelitian ini adalah untuk mengetahui ketahanan 3 varietas nilam terhadap penyakit budok, dan mengetahui efektivitas dari formula tunggal dan campuran minyak mimba dan seraiwangi terhadap kejadian penyakit budok dan pengaruhnya pada pertumbuhan tanaman. Penelitian ini terdiri dari dua percobaan: 1) Efektivitas metode infeksi dan uji ketahanan tiga varietas nilam terhadap penyakit budok di rumah kaca, dan 2) Uji efektivitas minyak atsiri formula tunggal maupun campuran mimba dan seraiwangi sebagai pestisida nabati terhadap penyakit budok. Hasil percobaan efektivitas metode infeksi menujukkan bahwa metode perendaman akar tanaman dalam inokulum budok selama satu jam lebih efektif menginfeksi penyakit budok dibandingkan dengan metode penyiraman ke media tanam. Hasil uji ketahanan nilam varietas Sidikalang, Patchoulina 1 dan Patchoulina 2 menunjukkan bahwa varietas Patchoulina 1 lebih rentan terhadap penyakit budok karena menimbulkan keterjadian penyakit (KeP) dan keparahan penyakit (KP) hingga 20%, dengan karekter pertumbuhan tinggi tanaman yang lebih rendah dibandingkan varietas lain yang diuji. Sedangkan diantara minyak atsiri yang diujikan, formula minyak atsiri campuran (mimba dan seraiwangi) konsentrasi 0.5% lebih efektif dalam mengurangi penyakit budok, namun efektivitasnya masih lebih rendah dibandingkan dengan perlakuan fungisida benomil 0,3% dan bubur bordo 0,1%. Aplikasi formula minyak atsiri secara signifikan tidak berpengaruh negatif terhadap pertumbuhan nilam, sehingga formula campuran (mimba dan seraiwangi) 0,5% dapat digunakan untuk mengontrol penyakit budok pada tanaman nilam.

A zoo is one of an ex-situ conservation activity whice aimed to conserve plants and wildlife animal an endangered position, for example; the Panthera tigris sumatrae population are decrease. The zoo were succeed to captivate an animal only if they can adopt their normal life into that place. The aim of this research was to study the animal welfare from Sumatran tiger in two different places; Bandung zoo and Ragunan zoo. This research has been conducted in Desember â€“ February 2017. The research method that are used in this study were interviewed and filling draft animal welfare from Indonesian Ministry of Forest No.P.9/VI-SET/2011. The Result of this research were 77% point for Ragunan zoo and 60% point for Bandung zoo which different mean both of that place. Filling draft animal welfare consist beside five freedom of animal welfare; 1). Freedom from hunger and thirst, 2). Freedom from discomfort, 3). Freedom from injury, paint, and disease, 4). Freedom to express natural behavior, 5). Freedom from fear and distress. The conclusion of this research were Ragunan zoo was better than Bandung zoo to applied animal welfare rules.

Research on coral reefs in Pulau Kayu Angin Genteng, Kepulauan Seribu, which was conducted several years ago, obtained the condition of coral reefs and the diversity was medium. Therefore, this study aims to determine the condition of coral reefs, diversity, and the composition of the latest corals that exist in the Kayu Angin Genteng Island. This research was conducted in February - March 2017. The method used descriptive and data retrieval technique with Underwater Photo Transect (UPT). The number of stations consists of 4 locations based on the direction of the wind (North, East, South and West). Each station made of 30 m long transects placed at 2, 4, 6, 8 and 10 m depth. In addition, environmental parameters measurements include temperature, dissolved oxygen (DO), salinity, pH, light penetration and current velocity. Analysis of photo data using CPCe application. The results indicated that the condition of coral reefs in Kayu Angin Genteng Island belongs to enough category and the condition of water quality still supports coral life. The diversity index is included in the medium category. There are 11 growth forms, 17 family and 48 coral genus, based on the highest growth form composition represented by Acropora.
