Gold processing waste contains many chemicals compound such as mercury and cyanide, which may help change the physical character of soil. In this study, the temperature, humidity and soil pH has been measured. Measurements of temperature and soil moisture are carried out using SHT11 sensors directly during gold processing. Measurements were carried out around the pond in three different directions. Each direction has 6 points, spaced 5 m apart. Measurements at one point are carried out for 20-21 hours. The measurement results are then mapped to a contour using Surfer-13. Based on the measurement results, obtained temperature values for all points are in the range 25.2-30.3 °C. While the value of soil moisture around 63.8-89.9%, and the soil pH value ranged from 6.8 to 8.1. The mapping results shows the distribution of temperature, humidity and soil pH with almost the same pattern, where the mercury concentration is linear with soil temperature, and soil pH, but non-linear with soil moisture

The research conducted in order to know farmer perception on goat reproduction in North Lombok District. Farmer groupswereselected by purposive random sampling. Each group represented by 10 respondents. Collected data then tabulated and quantified, interpreted and presented descriptively. The initial populations in the past 5.6 years were 243 (50 males and 193 females), currently remaining458 (340 females and 118 males) excluding those weresold. 80% of respondents know the age of doe’s at the first mating and 88.8% know oestrus signs. 67% of respondents did not know post kidding open days. 100% doe's were naturally mated. 50% respondents stated mating frequenciesfor optimum fertility rate was 1-2 times, 12% said 3-4 times and the remaining 38% did not know. Only 56.7% of respondents knew doe’slength ofpregnancy. Doe’s with twins of two or morekidding were 59.3% and single kid was 40.70%. Almost 100% of respondents know genetically superior bucks. In conclusion, on one hand the perception of respondent's on goat reproduction is relatively low, but on the other hand the goat production was relatively high. To accelerate the increase in productivity of goats in North Lombok Regency, was recommended that local goats are crossed with superior goats such as Ettawa goats or Boer goats

TA descriptive research aimed to identify the characteristics and name of main soils in Lombok Island was carried out through field observation for soil profiles and landform and laboratory analyses for soil physical and chemical properties. The type or name of soil was defined by using The National (Indonesian) Soil Classification System (2014), Soil Taxonomy (SSS-USDA, 2014), and World Soil Reference (FAO, 2014). There were 4 main types of soil in Lombok Island, which were Litosol, Aluvial, Kambisol, and Vertisol; and a fairly developed soil in limited spots was Mediteran. Based on the soil taxonomy system, those soils were respectively equivalent to Orthents, Fluvents, Undepts, Underts, and Udalfs; whereas based on the soil system of FAO, were Leptisols, Fluvisols, Cambisols, Vertisols, and Luvisols. The main characteristics of Litosol/Orthents/Leptosols Lombok were shallow solum (< 25 cm on the rocks or lithic contacts), coarse textured (sandy), nutritionally deficient, very low CEC (< 5 cmolc.kg-) and C-organic content (< 1 %). Aluvial or Fluvents, were mainly utilized as paddy soil, consisting of several layers which it clay and C-organic content were changed irregularly with depth, CEC of top soil (Ap) was medium (5–10 cmolc.kg-), and it was relatively fertile. Kambisols or Undepts was fairly deep (consisting of 40 – 60 cm of A and B horizons,), loamy textured, fairly fertile, CEC was medium, and C-organic content was low – medium (1–2 %). Vertisol or Uderts was characterized by a significant swell-shrinking properties, clay textured, extremely hard to be cultivated, high CEC, Ca, and Mg, and relatively fertile soil. Mediteran or Udalf was a further developed soil (solum > 100 cm), clay translocation has been occurred from upper (E) to lower horizons (Bt), CEC was fair, and it was relatively fertile soil. In conclusion, the pedologic development of soils in Lombok Island was relatively slow due mainly to the low–moderate rainfall, and the soil types were dominated by Litosols, Aluvials, Kambisols, and Vertisols, and Mediteran in small area. In order to provide a complete reference for the characteristics of main soils in Lombok Island, it necessaries to define mineralogy composition through X-ray diffraction analysis (XRD) and thermogravimetry analysis (TGA) of the clay fractions of the soils
