The major rice intensity of diseases in Indonesia was increased significantly and has caused a yield loss of up to 20–30%. The experiments had been conducted to investigate the effect of bioameliorant or composted straw (CS) combined with consortia of biofertilizers (CB) and biocontrol agent to restore the soil health and promote the induced systemic resistance (ISR) for increasing the rice productivity. The experiment arranged as randomized block design consisted of 12 treatments (0, 2.5, 5.0 and 7.5 ton of CS per ha combined with 400 g of CB and 200 g inoculant of CB + 200 g inoculant of Trichoderma sp and was provided with three replications. The experimental results revealed that application of 2.5–7.5 ton per ha of bioameliorant combined with 400 g per ha of CB and 400 g Trichoderma sp has increased the ISR and enhanced the rice productivity significantly. The brown spot, sheath rice blight and bacterial leaf blight diseases were reduced from 16.7% to 3.3–8.0%, 20% to 4–10%, 24% to 2.7–4.7% and 20.7% to 8–14.0%, respectively at 7 weeks after transplanting. In addition, the rice grain yield was increased from about 7.1 ton ha−1 to 7.9–10.1 ton per ha.

Ultisol is soil that have problem of soil acidity, low organic matter and low available macro nutrient in particularly low P availability. This is only small part of phosphorus is available for plant because most of the phosphate was still present in the soil were fixed by soil colloids. Some soil microbes are known phosphate solubilizing microbes have capability to dissolve phosphate that transform of P fixed into the soluble P. The field experiment conducted at Jatinangor, West Java Indonesia to determine the effect of PSM on phosphate solubility, growth and yield of maize and phosphorus fertilizer efficiency. Design experiment of Randomized Block Design (RBD) was used in field experiment, consisted of two factors and three replications. Phosphate solubilizing microbe as the first factor consisted four levels i.e without, phosphate solubilizing bacteria (PSB), phosphate solubilizing fungi (PSF), mixture of PSB and PSF. While the second factor was P fertilizer consists five levels (0%, 25%, 50%, 75% and 100% doses of recomendation). The results of the field experiment showed that application of phosphate solubilizing microbes significantly improve the yield of maize in Ultisol Jatinangor, but did not significantly affect on soil P, available soil P, phosphatase and P uptake of plants. Application of a mixture of PSB and PSF better effect on soil available P and yield of maize. Phospate fertilizer dosing at a dose of 25 % , 50 % , 75 % and 100 % recommendations increased available soil P. Fertilizer of P could inhibit the activity of phosphatases. Phosphate fertilizer with dose 50 % recommendation gave better effect on soil P and yield of maize.

We present a wearable time-domain near infrared spectroscopy (TD-NIRS) system (two wavelengths, one detection channel), which fits in a backpack and performs real-time hemodynamic measurements on the brain and muscle tissues of freely moving subjects. It can provide concentration values of oxygenated hemoglobin (O 2 Hb), deoxygenated hemoglobin (HHb), total hemoglobin (tHb = O 2 Hb + HHb) and tissue oxygen saturation (StO 2 ). The system is battery-operated and can be wirelessly controlled. By following established characterization protocols for performance assessment of diffuse optics instruments, we achieved results comparable with state-of-the-art research-grade TD-NIRS systems. We also performed in-vivo measurements such as finger tapping (motor cortex monitoring), breath holding (prefrontal cortex monitoring and forearm muscle monitoring), and outdoor bike riding (vastus lateralis muscle monitoring), in order to test the system capabilities in evaluating both muscle and brain hemodynamics.

Subterranean termites are a group of termite that causes economical loss in the timber and crop cultivation business. In Indonesia, subterranean termites are found attacking garden plants and forest plants such as coconut tree, cocoa tree, palm oil tree, and pine tree. Besides, subterranean termites also damage a lot of construction buildings which are made from wood. In Indonesia, it is difficult to effectively prevent the growth of subterranean termite. One of methods to improve wood durability towards subterranean termite threat is to preserve the wood. Sengon tree bark extract, soursop leaf and tobacco leaf are considered to be used as natural preservatives. This research is aimed to find out the effect of extractives of sengon wood, soursop leaf, and tobacco leaf on the mortality of subterranean termite, and this research is aimed to find out which extract substance that has the most retention, mostly affects subterranean termite mortality, and has the least weight loss. This research used an experimental method carried out in the laboratory, using a complete randomized design design, with four treatments that were repeated five times.\ The results showed that the extractives of sengon bark, soursop leaves and tobacco leaves had an effect on reducing the mortality rate of soil termites but were not significantly different in the retention rate. However, tobacco leaf extractive substance has the most effect in reducing the intensity of subterranean termite invasion and causing the least damage.
