Australia is about to become the premier global exporter of liquefied natural gas (LNG), bringing increased opportunities for helium extraction. Processing of natural gas to LNG necessitates the exclusion and disposal of non-hydrocarbon components, principally carbon dioxide and nitrogen. Minor to trace hydrogen, helium and higher noble gases in the LNG feed-in gas become concentrated with nitrogen in the non-condensable LNG tail gas. Helium is commercially extracted worldwide from this LNG tail gas. Australia has one helium plant in Darwin where gas (containing 0.1% He) from the Bayu-Undan accumulation in the Bonaparte Basin is processed for LNG and the tail gas, enriched in helium (3%), is the feedstock for helium extraction. With current and proposed LNG facilities across Australia, it is timely to determine whether the development of other accumulations offers similar potential. Geoscience Australia has obtained helium contents in ~800 Australian natural gases covering all hydrocarbon-producing sedimentary basins. Additionally, the origin of helium has been investigated using the integration of helium, neon and argon isotopes, as well as the stable carbon (13C/12C) isotopes of carbon dioxide and hydrocarbon gases and isotopes (15N/14N) of nitrogen. With no apparent loss of helium and nitrogen throughout the LNG industrial process, together with the estimated remaining resources of gas accumulations, a helium volumetric seriatim results in the Greater Sunrise (Bonaparte Basin) > Ichthys (Browse Basin) > Goodwyn–North Rankin (Northern Carnarvon Basin) accumulations having considerably more untapped economic value in helium extraction than the commercial Bayu-Undan LNG development.

Red Chilli is commodity of vegetable that has high economic value, but still has slow productivity. The objective of this study was identify the effect of indigenous microorganism (EM 4) application and compost to increased the growth and yield of Red Chilli Plant (Cappcicum annum L) on Ultisol. Field trial was conducted on Ultisols in Horticulture Experimental Station, BatuahLoajanan, Kutai Kartanegara. The soil was characterized by low fertility status. The amount of organic matter and microbial acivity are very low. This trial was started on January until April 2017 using Split Plot Design with three replications Main plot consisted of two levels treatment i.e. without EM-4 (E0) as control and Effective Mikroorganisms-4 (E). Sub-plot was four rates of organic compost i.e. 0, 10, 20 and 30 tons ha-1 and chili was used as test plant.Results indicated that EM-4 treatment showed a significant effect on fruit yield of chilli. It increased the fruit yield 38 percent compare to control. Compost application significantly increased on fruit yield. The relationship between unfermented compost rate and fruit yield shows a linear regression YE0 = 1.699 + 0.047 X (r = 0.95) and quadratic regression for EM-4 fermented compost YE1 = 1,175 + 0,319 X – 0.007 X2(R2 = 0.603). Optimum compost rate was 23 ton.ha-1.To increased fruit yield of chilli, EM-4 fermented compost should be applied into and it can decreased compost rate application.

Photoreduction of carbon dioxide is one of the promising method to reduce green house gas emission. Carbon dioxide can be converted into organic chemical that has higher economic value by utilizing light energy. One of the favorable product is formic acid which is can be used as hydrogen-carrier. For this process, photocatalyst plays important role as it can increase the rate of reaction and as well as the selectivity as such more desirable product can be produced. The objective of present study is to develop photocatalyst which can significantly catalyze the photoreduction process of CO2 to form formic acid. Zinc titanate doped with aluminium is used as the base photocatalyst. Photoreduction process is held in room condition using three 2800 lm lamp. Qualitative analysis of the product is done by silver solid test and acidity test while quantitative analysis is done by High Performance Liquid Chromatography (HPLC) test. The silver solid test results confirm that formic acid is formed during process. Based on acidity profile data, anthocyanin as photosensitizer could increase higher acidity in the mixture than melanin. However, the concentration of formic acid in the solution is still very low so that it cannot be detected by HPLC.
