Evaluation and Selection of Mutative Artemisia (Artemisia annua L.) According to the Altitude Variants
HAYATI Journal of Biosciences , 2011,
Abstract: Induction of genetic variant of Artemisia annua L. was conducted through the application of gamma ray irradiation in 2007-2008. The aim was to obtain a plant with high artemisine content > 0.5% and late flowering period of about > 7 month after planting. Tweleve selected genotypes were subsequently examined to gain genetic stability on altitude of 1500, 950, and 540 m asl. The results showed that the plants had shorter flowering age in Cicurug (540 m asl) than that of in Pacet (950 m asl) and Gunung Putri (1540 m asl). Genotype 8 had the latest age of flowering in the three locations than the other genotypes, however, the growth and biomass were the lowest. Vegetative growth of Artemisia in Pacet and Gunung Putri was better than those in Cicurug. Genotype of 15 in Cicurug and 5A genotype in Gunung Putri and Pacet had higher wet and dry weight than that of two other associates. Based on plant biomass, 5 genotypes from Gunung Putri and Pacet i.e. 1D, 3, 5A, 14, and 15 genotypes were selected, as well as 5 genotypes i.e. 1D, 3, 4, 5A, and 15 genotypes from Cicurug. Analisys on artemisin content successfully obtained 5 selected somaclone lines i.e. 1B, 2, 4, 14, and 3 somaclones.

Jurnal Tanah Tropika , 2012,
Abstract: Turnover of organic matters to the soil can increase the efficiency of chemical fertilizers, improve the plant growthand sustain the environment. Field experiment was carried out in the Buyut Udik Village, Gunung Sugih District,Central Lampung from May to August 2009. Rice straw was composted by three kinds of decomposer (bioactivatorA, B, and C). Rice straw compost (2 Mg ha-1) was applied to the paddy-field soil that was planted by rice (Oryzasativa) of Ciherang Variety. The experiment was arranged in a randomized block design with three replicates. Theresults showed that application of rice straw compost reduced the numbers of empty grain per tiller compared tocontrol (without compost) in which control had the highest percentage of empty grain (15.9%). The application ofrice straw compost that was decomposed by bioactivator A gave the highest numbers of grain per panicle and yieldper plot as followed 162.5 seed and 33 kg plot-1, respectively. Application of various rice straw composts that weredecomposed by three kinds of bioactivator increased the rice grain up to 13-26% compared to control.
Solvent Extraction of Nickel and Cobalt from Ammonia-Ammonium Carbonate Solution by Using LIX 84-ICNS  [PDF]

International Journal of Nonferrous Metallurgy (IJNM) , 2015, DOI: 10.4236/ijnm.2015.43003
Abstract: In the present paper, separation of nickel and cobalt in ammonia-ammonium carbonate solution that simulates pregnant leach solution of Caron Process by solvent extraction using LIX 84-ICNS was studied. LIX 84-ICNS is a novel extractant which is still being studied, especially for nickel and cobalt separation in ammonia-ammonium carbonate solution. A series of solvent extraction tests were performed at various equilibrium pH, temperature, extractant concentration, and volume ratio of organic to aqueous solution (O/A ratio). The investigation results show that the highest nickel and cobalt extraction percentages of 99.8% and 90.3% were obtained from the extraction test at equilibrium pH of 8.75, temperature of 55°C, extractant concentration of 40% (v/v) and O/A ratio of 1/1, respectively. Oxidation of cobalt in aqueous solution prior to extraction is needed to minimize co-extraction of cobalt. Co-extracted cobalt can be decreased from 90.3% to 30.3% by mixing 1% (v/v) H2O22 in aqueous solution prior to the extraction stage. It was found that nickel and cobalt extractions by LIX 84-ICNS are endothermic processes with enthalpy changes of +171.03 and +7.64 kJ/mole, respectively. Based on constructed McCabe-Thiele Diagram, nickel extraction level of more than 99.9% can be obtained in 2 stages at O/A ratio of 0.5. The highest stripping percentages of nickel and cobalt of 98.82% and 3.16% respectively were obtained at 200 g/l H2SO4 stripping agent.

Abstract: One primary need is housing, so developers must build it, but consumers are now more selective in buying housing. The developer who has a good concept and accountability can attract consumers, especially middle to high income buyers. This research discusses the relationship between accountability of developers, viewed from the type of attention given to security, environmental cleanliness, street conditions, street lighting, drainage, and parks, for housing developments which are not finished being built, with variables such as experience, region, estate management, and cost. The results show that the ten developers who were analyzed have good accountability for their unfinished housing development especially Graha Family and Araya Bumi Megah. Abstract in Bahasa Indonesia : Salah satu kebutuhan primer adalah rumah tinggal, maka diperlukan peran serta pengembang untuk menyediakannya, namun konsumen saat ini lebih selektif dalam membeli rumah. Pengembang yang memiliki konsep dan akuntabilitas baik, yang dapat menarik calon konsumen terutama konsumen menengah ke atas. Penelitian ini membahas hubungan akuntabilitas pengembang ditinjau pada jenis pemeliharaannya, yaitu pada segi keamanan, kebersihan lingkungan, kondisi jalan, penerangan jalan, saluran, dan taman untuk kawasan perumahan yang belum selesai dibangun dengan pengalaman kerja, wilayah pengembangan, keberadaan estate management, dan biaya pemeliharaan. Ternyata hasil penelitian menunjukkan bahwa ke-sepuluh pengembang yang diteliti memiliki akuntabilitas pada pemeliharaan kawasan perumahannya yang belum selesai dibangun, khususnya Graha Famili dan Araya Bumi Megah.
