Most community of Pejalin Village has profession as paddy farmers in shifting cultivation. Farmers  in Pejalin Village cultivate paddy with some varieties such as E’ho, Libang, and Usunuan. Some farmers in Pejalin Village sometimes use a lot of inputs, they hope to get high yield. However, the use of a lot of inputs will increase production cost then decrease profit of farming. This research aimed to analysis paddy farming in shifting cultivation by using the varieties of E’ho, Libang, and Usunan. Method that used in this research was method of descriptive qualitative. Determination of sampling uses cencus sampling with 35 respondents. The result of this research showed high cost in farming of Libang variety with cost as much as IDR3,060,725.00 then E’ho variety with cost as much as IDR2,900,687.00 and Usunuan variety with cost as much as IDR2,335,816.00.  The highest income in farming of E’ho variety as much as IDR6,348,785.00 then Libang variety as much as IDR5,203,175.00 and Usunuan variety as much as IDR4,514,530.00 in a planting season. R/C ratio was 3 showed paddy farming that done by farmers is feasible and profitable.

ABSTRACT 1. An indirect paperchromatographic method is described for separating urinary oestrogens; this consists of the following steps: acidic hydrolysis, extraction with ether, dissociation of phenol-fractions with partition between the solvents. Previous purification of phenol fraction with the aid of paperchromatography. The elution of oestrogen containing fractions is followed by acetylation. Oestrogen acetate is isolated by re-chromatography. The chromatogram was developed after hydrolysis of the oestrogens 'in situ' on the paper. The quantity of oestrogens was determined indirectly, by means of an iron-reaction, after the elution of the iron content of the oestrogen spot, which was developed by the Jellinek-reaction. 2. The method described above is satisfactory for determining urinary oestrogen, 17β-oestradiol and oestriol, but could include 16-epioestriol and other oestrogenic metabolites. 3. The sensitivity of the method is 1.3–1.6 μg/24 hours. 4. The quantitative and qualitative determination of urinary oestrogens with the above mentioned method was performed in 50 pregnant and 9 non pregnant women, and also in 2 patients with granulosa cell tumour.

The purpose of this study was to develop a method for rapid quantitative and qualitative determination of the oil from microalgae lipid fraction obtained from Nannochloris sp biomass. The lipid fraction was first refluxed with 4% KOH in MeOH (60, 90, 120 min), followed by reaction with 20% BF3 in MeOH, using different times of reflux (90,120, 150 min) for each time of reflux with 4% KOH in MeOH. The FAME samples were analyzed by GC-MS analysis. 120 min reflux with 4% KOH in MeOH, 90 min with 20% BF3 in MeOH and a ratio lipid fraction: 4% KOH in MeOH: 20% BF3 in MeOH=1:20:27, were required to obtain the higher percent of oil in the microalgae lipid fraction. The relevance of the method developed was proved by TGA analysis and by transesterification of a sunflower oil sample in the same conditions.

Abstract Nitric oxide (NO) is known to mediate many beneficial physiology processes, motivating its detection in vivo as well as in vitro. Electrochemical detection provides the required cellular level determination of NO among several other techniques. In this work, electrochemical micro-sensors for both types of detection, in vivo and in vitro, were developed, exploring the silicon planar technology, which presents high yield and reliability and also permits batch fabrication. The developed in vitro sensor features eight detection sites (10 μm × 10 μm microelectrodes), for determination of nitric oxide spatial distribution or multi-species analysis. Different electrochemical methods were applied to provide sensor calibration and chemical reproducibility. For in vivo analysis, the designed structures have a needle shape (40 μm thick) and they were silicon micro-machined by using plasma etching or etch stop techniques. Different configurations were designed and implemented, containing a number of detection microelectrodes that vary from 2 to 10. The amperometric detection of both nitric oxide and nitride (NO2−) — a molecule that causes an interference — were investigated by using the in vitro micro-sensor configuration. The need of a cationic exchanger (Nafion) was demonstrated in order to provide selectivity to NO for low concentrations. Also, the developed sensor has a sensitivity of 500 A/M.cm2 and a detection limit of 10 μM.

This article aims to describe: the implementation of the SQ3R model to the ability to examine the characters contained in fiction texts in grade IV students of SDN Ganung Kidul 1 Nganjuk in the 2019/2020 Academic Year. This article is an descriptive qualitative research carried out through five stages, namely: (1) data collection; (2) determination of the sample; (3) recording data; (4) reduction; and (5) drawing conclusions. Data sources in this article are journals and books relating to the learning of the SQ3R model on learning to examine the characters contained in fiction texts. These data provide an overview of the application of the SQ3R model on the ability to examine the characters contained in fictional texts. Furthermore, the object of the research is the learning model SQ3R with a subject of 22 students. The conclusion of the article shows that: this SQ3R model is very good to be applied to the basic competencies of Indonesian language class IV semester II, namely the ability to examine the characters contained in fiction texts.
