Worms are diseases caused by the entry of parasites (in the form of worms) into the human body. The types of worms that are often found to cause infection are roundworms (Ascarislumbricoides), whipworms (Trichuris trichiura) and hookworms (Necatoramericanus) which are transmitted through the soil (Soil Transmitted Helminthiasis. Examination of helminth infections can be done qualitativelyand quantitative. The qualitative examination that is often used is the Direct slide method. while the quantitative examination that is often used is the Kato Katz method. This study aims to compare the accuracy of the worm infection examination between the Direct slide method and the Kato Katz method by examining stool samples. This research was conducted on 47 Ampenan Elementary School Students located on the coast in Mataram City, where the coastal area is one of the good breeding grounds for worms. This study used a comparative analytical research design with a cross sectional approach. To establish the diagnosis of helminthiasis and the type of worm that infects, an examination of worm eggs in stool samples is carried out using the Direct slide and Kato Katz methods. The results showed that the number of samples infected with STH was more commonly found by the Kato-Katz method. The results of measurements using the Direct slide method and the Kato Katz method showed that the highest prevalence of STH infection was Ascaris lumbricoides infection. Direct slide method produces a sensitivity level of 95.16% and a specificity of 100%.

Lombok is an area with the highest geomagnetic anomaly in Indonesia (Zubaidah et al., 2014). From the end of July to the end of August 2018, Lombok experienced a series of fairly large earthquakes. Identification of geomagnetic signals, especially in the Ultra Low Frequency (ULF) spectrum, can be used as earthquake precursors (Saroso, 2010). Intermagnet IAGA (International Aeronomy Geomagnetic Association) is a network of international geomagnetic observatory stations that have large world geomagnetic data. Big data analysis is very important because very large information is needed in disaster mitigation. This study uses geomagnetic data per second for 24 hours from 28 August to 30 November 2018 taken from Kakadu (KDU) Australia and Nurul Bayan Station (NRB) Lombok. The analytical method used is Differentiation by calculating the F value (total magnetic field) for KDU and NRB, then look for the difference and analyze the pattern. The results found that there was an anomaly phenomenon of the Earth's magnetic field in Nurul Bayan Lombok which was detected for 17 days during October 2018.
龙目岛是印尼地磁异常最严重的地区(Zubaidah et al.， 2014)。2018年7月底至8月底，龙目岛经历了一系列相当大的地震。地磁信号的识别，特别是在超低频(ULF)频谱中，可以用作地震前兆(Saroso, 2010)。国际航空地磁协会(IAGA)是一个拥有大量世界地磁数据的国际地磁观测站网络。大数据分析非常重要，因为在减灾中需要非常大的信息。本研究使用了2018年8月28日至11月30日24小时内从澳大利亚卡卡杜(KDU)和龙目岛Nurul Bayan站(NRB)采集的每秒地磁数据。使用的分析方法是通过计算KDU和NRB的F值(总磁场)来区分，然后寻找差异并分析模式。结果发现，2018年10月，在努鲁巴扬龙目岛发现了地球磁场异常现象，持续了17天。

The use of inorganic fertilizers has an important role in increasing plant growth and production. But it also causes various problems such as decreasing soil organic matter, soil acidity, soil degradation, nutrient imbalance and increasing environmental pollution. Therefore, it needs to be balanced with the provision of organic fertilizers. A field experiment was conducted to study the effect of application of various doses of inorganic and organic fertilizers on N, P, K nutrient uptake and maize plant growth. The experimental design used was a randomized block design arranged in a factorial manner consisting of two factors. The first factor is the dose of inorganic fertilizer (A): 0, 150 and 300 kg ha-1 phonska and the second factor is organic fertilizer plus (P): 0, 10, 20 tons ha-1. The two factors were combined and each treatment combination was repeated three times. The data obtained were analyzed by analysis of variance at the 5% level of significance. The results showed that there was no interaction between the application of inorganic and organic fertilizers on the growth and nutrient uptake of N, P and K. However, the application of inorganic and organic fertilizers had a significant effect on all tested agronomic traits except for plant height. Nutrient uptake of N, P and K also increased significantly due to the application of inorganic and organic fertilizers. The balance of inorganic and organic fertilizer application increases the availability of nutrients as well as the uptake of N, P, and K nutrients by maize plants.
无机肥料的使用对促进植物生长和产量具有重要作用。但也造成了土壤有机质减少、土壤酸化、土壤退化、养分失衡、环境污染加剧等问题。因此，需要与有机肥的提供相平衡。通过田间试验，研究了施用不同剂量无机有机肥对玉米氮、磷、钾养分吸收及植株生长的影响。试验设计采用随机区组设计，由两个因子组成。第一个因素是无机肥用量(A): 0,150和300 kg ha-1 phonska，第二个因素是有机肥加(P): 0,10和20吨ha-1。两因素联合治疗，每种联合治疗重复3次。对所得资料进行5%显著性水平的方差分析。结果表明，施用有机肥和无机肥对水稻生长和氮、磷、钾的养分吸收没有交互作用，但施用有机肥和无机肥对除株高外的所有农艺性状均有显著影响。施用无机和有机肥也显著增加了氮、磷、钾的养分吸收量。无机和有机肥料施用的平衡增加了养分的有效性以及玉米植株对N、P和K养分的吸收。

Weeds are not always detrimental to plants, because there is a period of time when they are most influential on plant growth and yield and a period of time when weeds are present is called critical piriode. A research aimed to determine the critical period of sweet corn with weeds in Central Lombok entisoles. The experimental research method with experiments in the field used a randomized block design (RBD), which consisted of 12 treatments, weed-free plants (TBG) from planting to age, 10;20;30;40;50 and 60 days and the plants were allowed to roll (TG). since planting until the age of 10;20; 30; 40;50 and 60 days. The results showed that the presence of tolerable weeds on sweet corn plants was only until the age of 30 days after planting. Weeds must be weeded after the plants are between 30-40 days old, if done after the plants are 40 days old, the crop yields cannot be saved. The critical period for sweet corn competing with weeds on the Lombok Tengan entisol is in the age range between 30-40 days after planting. Plants that compete with weeds for 40, 50, and 60 days after planting (until harvest) experience a decrease in yield of 60.32%, 82.84% and 98.66%. Meanwhile, plants that did not compete (weed free) for only 10, 20 and 30 days experienced a decrease in yield of 98.61%, 80.16% and 61.40%.

through the development of carbon zinc as an organic material produced from photosynthesis and stored and transported in the form of seagrass vegetation biomass. Seagrass is one of the aquatic vegetation that is able to absorb and store carbon. Seagrasses have the ability to absorb carbon through the process of photosynthesis. The purpose of this study was to describe the potential carbon content of seagrass species in the South Coastal Waters of East Lombok. This type of research is an expolarative descriptive research. The research method is a quadratic transect method. The population of this study were all seagrass species contained in 3 research stations. The collected data was then analyzed using analysis of seagrass species composition, seagrass cover, seagrass density, diversity, uniformity, dominance and analysis of carbon content through seagrass stand biomass (leaves, rhizomes/stems and roots). The result of this research is the discovery of 9 species of seagrass on Lungkak Beach and 5 species of seagrass on Gili Kere and Poton Bakau. The species density in the three study sites ranged from 0.09 to 56.91 stands/m2. Seagrass biomass values ranged from 1.47-261.9 gbk/m2 and total carbon content ranged from 295.91±202.88 gC. The value of this biomass and carbon content was dominated by seagrass species with large morphology such as Enhalus acroides, Thalasia hemprici, Cymodocea rotundata, and Cymodocea cerillata and high density and cover values of seagrass. The relationship between seagrass cover and seagrass carbon has a significant relationship where the higher the seagrass cover, the higher the carbon content of the seagrass.

The parameters observed included: type of feed offered, the amount provided and frequency of feeding, harvest weight, and FCR. Phase II. Evaluation of the chemical composition of the diet used in partnership broiler farming system. The parameters observed included: the moisture, ash, protein, fat and fiber. The data obtained were tabulated and discussed descriptively. Based on the survey results, there are 8 partnership companies, namely PT. MSJ, PT. BBB, PT. Samsung, PT. DMC, PT. BSS, PT. FMS, PT. KUS and PT. PAL, and 6 types of feed used, namely S12, GM-PS, GM 1 EJ, Malindo, Wonokoyo, HD BR1 161. Average feed consumption is 3.24 kg / head / period, with weight gain of 2.10 kg / head / period, with the FCR value of 1.54. Based on the results of the evaluation of the nutritional content, there is a mismatch, especially the protein content which is lower (0.01%) as shown in the leaflet of the starter feed from Wonokoyo company. The conclusion of this study is that in general, the complete feed quality used is in accordance with the SNI based feed quality standards and the broiler productivity produced on partner farms meets the company standards.

This study aims to determine the average leaf angle, harvest age and yield of F1 from cross-hybrid composite; heterosis value and knowing the maternal effect of these three traits on maize. The experiment was carried out in technically irrigated rice fields from November 2019 to February 2020. The design used in this experiment was a randomized block design with two replications. The treatment was 28 F1 as a result of crossing P8IS vs NK212 and P8IS vs NK7328 and their respective reciprocal crosses. The experimental data were analyzed by means of analysis of variance and further tested with the LSD test at the 5 percent level. Heterosis values were calculated on the basis of the parents whose scores were higher (High Parent Heterosis). The t test at the 5% level was used to determine whether the maternal effect was significant. The results showed that the mean leaf angles of F1 lines from crosses and reciprocal P8IS vs NK212 were the same as the two parents; whereas the P8IS vs NK7328 cross is different. The reciprocal of cross number 13 (P8IS vs Nk7328 /R13) has smaller leaf angle than P8IS and is the same as the leaf angle of NK7328. The yield of the F1 lines from the two types of crosses was the same as each of the two parents; however, there was a tendency for an increase in yield compared to P8IS for most of the F1 lines. There was a change in leaf angle properties, harvest age and yield of F1 lines compared to one of the best parents with heterosis values are negative and positive with variations from 0.00 to 65.70 percent. Coefficient of correlation between heterosis with the average value of traits was classified as strong for the harvest age; moderate for yield and weak for leaf angle. These three traits in the two types of crosses showed no maternal effects. Smaller leaf angle, super early harvest age and higher yield, are possible to be obtained from the lines of both crosses.
本研究旨在通过杂交组合确定F1的平均叶角、采收期和产量;这三个性状在玉米上的杂种优势价值及其母系效应的认识。该试验于2019年11月至2020年2月在技术灌溉稻田进行。本试验采用随机区组设计，2个重复。通过P8IS与NK212和P8IS与NK7328及其互交杂交，处理为28f1。实验数据采用方差分析方法进行分析，并在5%的水平上进行LSD检验。以得分较高的亲本计算杂种优势值(高亲本杂种优势)。采用5%水平的t检验确定母体效应是否显著。结果表明:P8IS与NK212杂交后的F1系叶片平均角度与亲本相同;而P8IS与NK7328交叉是不同的。十字数13的倒数(P8IS vs Nk7328 /R13)的叶角小于P8IS，与Nk7328的叶角相同。两种杂交组合的F1系产量与亲本相同;然而，与P8IS相比，大多数F1系的产量有增加的趋势。与杂种优势值最高的亲本相比，F1系的叶角性状、收获年龄和产量均呈负、正变化，变化幅度在0.00 ~ 65.70%之间。杂种优势与各性状平均值的相关系数在收获期为强;产量适中，叶角较弱。这3个性状在两种杂交中均无母系效应。两个杂交系均可获得较小的叶角、超早收获期和较高的产量。

Currently, there are many efficient and effective sprinkler irrigation tools on the market, so it is necessary to be careful in choosing for irrigation. Among them, the Meganet 24D Netafim, including the type of irrigation tool, which still needs testing to know its performance. This study aims to examine the sprinkler irrigation performance of Meganet 24D Netafim, on variations in flow rate and distance between sprinklers, related to irrigation uniformity (CU) and irrigation radius (Rn). This test was carried out on an area of about 1 acre, at a flow rate of Q1=0.42/sec, Q2=0.51 l/sec, Q3=0.52/sec, Q4=0.56 and the test sprinkler distance, r1=2 ,5m, r2=3m,r3 = 3.5m and r4 = 4m. The results of data analysis are presented in the form of tables and graphs and concluded descriptively. The results showed that, in all variations of Q and sprinkler spacing r1, r2, r3 obtained irrigation uniformity (CU) above 85% which was classified as high, while in the r4, Q1 and Q2 tests, CU was obtained below 85% which was considered low. All discharge variations, showing irrigation radius (R) about 5 m. So at r4 sprinkler spacing, it is not recommended in irrigation applications.
