Abstract

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 Aβ 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 (Aβ) and inflammation inside the patient’s brains; and as mention above curcumin had shown its capabilities in inhibiting the Aβ plaques and act as an anti-inflammation agent.

Abstract

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 ° C). Prolonged heat stress was given to 24 quails grouped in four groups: A (39 ° C), B (41 ° C), C (43 ° C) and D (45 ° 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 ° C can cause oxidative stress due to heat stress in quail.

Abstract

Developing of jewawut cultivation as an alternative source of carbohydrates is one of the efforts to prevent food insecurity. Drought conditions and the availability of drought-tolerant seeds became one of the problems in the development of jewawut cultivation. The purpose of these experiments were to evaluate jewawut response to drought stress simulations at germination phases and to obtain accessions tolerant to drought stress. Drought stress is performed indirectly (PEG 6000 selective media). The research was done in Laboratory of Physiology of Faculty of Mathematic and Science, UNJ from February until July 2017. The experiments were done with a completely randomized design. Parameters of germination were analyzed with Anova test and continued by Duncan Multiple Range Test (DMRT). Lethal doses of PEG reducing 50% of germination (LD50) were 23,25%, with the quadratic equation y = 1,12-2,72x. The results base on germination phase, Buru merah as drought tolerance accessions, Polman merah and Polman kuning as medium tolerance accession, and Buru kuning as susceptible accessions.

Abstract

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.
