Community structure analysis is one way to describe and assess the environmental quality of an ecosystem. One part of environmental biotic that make up mangrove water ecosystems is bivalves. The mangrove area in the Pangkajene river estuary has become one of the bivalve habitats, which has been widely used by the community. Research on the bivalve community structure of the mangrove area in the Pangkajene river estuary was conducted in April - June 2019, which aims to get an overview and assess the environmental conditions of the mangrove area in the Pangkajene river estuary based on the bivalve community structure. The research place was divided into three stations, each station was divided into two sampling areas, and in each sampling area six sampling points were placed. Sampling was carried out using a 50 x 50 cm plot method. Community structure limits calculated include density, diversity index, uniformity, dominance, and dispersion, as well as measurement of water parameters including pH, Organic C, and substrate texture. The results showed that the composition of bivalve community types consisted of 19 species included in 12 families. The dominant type is Saccostrea sp. with a density of 15.11 ind / m2 (Cr 50.77%). The species diversity index value ranges from 0.91 - 1.91 with an average of 1.50, which indicates the level of diversity of bivalves is relatively low. The Bivalvia community uniformity index includes the unstable criteria and the level of dominance index includes the stable community criteria, with a uniform distribution pattern.

Hyptis capitata is a plant in the family of Lamiaceae used to prevent wound infection and as an antidote for food poisoning by the Bentian people, a local tribe in East Kalimantan, Indonesia. Of the plants in the Lamiaceae family, the biological activities and phytochemical studies of H. capitata are less reported. This work aims to investigate the phytochemicals and biological activities of H. capitata grown at two locations in East Kalimantan, Indonesia. Leaves of H. capitata collected from location 1, Samarinda (coded by HSM), and location 2, West Kutai areas (coded by HWK), were macerated using ethanol. The biological activities of the plant were evaluated in terms of antimicrobial and antioxidant activity, and cytotoxicity against Artemia salina, while phytochemicals were analyzed by qualitative and quantitative tests. The results showed that leaf extract of H. capitata contains alkaloids, flavonoids, tannins, carbohydrates, and coumarins. HSM possessed higher phenolic and flavonoid content than that of HWK. HWK displayed more antimicrobial activity against the test microorganisms particularly P. acnes (29%), S. sobrinus (49%), S. aureus (51%), and E. coli (45%). HSM showed more radical scavenging activity in 1,1-diphenyl-2-picrylhydrazyl (IC50 13.69 μg/ml) and superoxide (IC50 65.11 μg/ml) tests. Brine shrimp lethality test showed no toxicity of H. capitata leaf extracts. The results displayed that H. capitata collected from the two locations showed good antibacterial and antioxidant activities. The results suggested that the biological activities and phytochemicals of H. capitata were affected by the environment where the plant was collected. A study into deep analysis of the effect of light intensity, temperature, soil nutrition, and predatory risks to the biological activity and phytochemicals of the plant is required.
海百合(Hyptis capitata)是一种唇形科植物,印度尼西亚东加里曼丹省的当地部落本提安人将其用作预防伤口感染和食物中毒的解毒剂。在唇形科植物中,H. capitata 的生物活性和植物化学研究报道较少。本研究旨在调查生长在印度尼西亚东加里曼丹两个地方的 H. capitata 的植物化学成分和生物活性。H. capitata的叶片采集自1号地点萨马林达(以 HSM 编码)和2号地点西古泰地区(以 HWK 编码),用乙醇浸泡。通过定性和定量测试分析了植物化学物质,并评估了该植物的抗菌、抗氧化和对鳀鱼的细胞毒性等生物活性。结果表明,H. capitata 的叶提取物含有生物碱、黄酮类、单宁、碳水化合物和香豆素。HSM 的酚类和类黄酮含量高于 HWK。HWK 对测试微生物显示出更强的抗菌活性,尤其是痤疮丙酸杆菌(29%)、梭状芽孢杆菌(49%)、金黄色葡萄球菌(51%)和大肠杆菌(45%)。HSM 在 1,1-二苯基-2-苦基肼(IC50 13.69 μg/ml)和超氧化物(IC50 65.11 μg/ml)测试中显示出更强的自由基清除活性。盐水虾致死试验表明,毛果芸香叶提取物无毒性。结果表明,从这两个地方采集的 H. capitata 具有良好的抗菌和抗氧化活性。结果表明,人头草的生物活性和植物化学物质受到采集环境的影响。需要深入研究分析光照强度、温度、土壤营养和捕食风险对该植物生物活性和植物化学物质的影响。

A decrease in the area of soybean farming has an effect on reducing soybean production from year to year so that it has not been able to meet the needs of national soybean consumption. Land suitability assessment is an effort to be able to optimize land use. In the process of assessing land suitability manually, it is considered inaccurate. The purpose of this study was to determine the land suitability class for soybean plants. The land suitability classification system used is the FAO land suitability classification classified at the sub-class level. Land suitability evaluation uses a matching system, as well as comparing the characteristics of land with plant growing community formulated in the technical evaluation of land guidelines for agricultural commodities. In the matching process Leibig's minimum law is used to determine the limiting factors that will affect the suitability of the class and sub-class of the land. Requirements for growing plants become kiteria in conformity evaluation. The results showed that the limiting factors of land suitability for soybean plants that had to be improved were temperature, rainfall, soil texture, C-Organic, N-Total and P-Available soil. The limiting factor of temperature and soil texture cannot be improved so that the marginal fit class (S3) on actual land suitability remains marginal fit (S3) in terms of potential land suitability.
大豆种植面积的减少,造成大豆产量连年下降,已不能满足全国大豆消费的需要。土地适宜性评价是一项能够优化土地利用的工作。在人工评估土地适宜性的过程中,它被认为是不准确的。本研究的目的是确定大豆植物的土地适宜性等级。所采用的土地适宜性分类体系为粮农组织土地适宜性分类的子类等级。土地适宜性评价采用匹配系统,并将土地特征与农产品土地技术评价指南中制定的植物生长群落进行比较。在匹配过程中,利用Leibig最小律确定影响土地类和次类适宜性的限制因素。植物生长要求成为合格评定的标准。结果表明,温度、降雨量、土壤质地、土壤c -有机、全氮和速效磷是制约大豆适宜性的主要因素。由于温度和土壤质地的限制因素无法改善,导致实际土地适宜性的边际拟合等级(S3)仍然是潜在土地适宜性的边际拟合等级(S3)。

Star fruit is a non-seasonal fruit that can be harvested three to four times a year. One possible way to process a star fruit is to make it into sorbet. Additional ingredients such as sugar and lime juice will help improve the quality of star fruit sorbet. The purpose of this study was to acquire the best formulation of honey star fruit sorbet by adding sugar and lime juice and to find out the effect of different concentration of sugar and lime juice on the level of predilection, physical traits, level of vitamin C, and antioxidants activity. This study consisted of two phases; the production of lime essence in phase one and the making of star fruit sorbet in phase two as the main study. The result of best formulations selected based on organoleptic test of panellists’ level of predilection were formulation of 150 g sugar + 30 g lime, 90 g sugar + 60 g lime, and 120 g sugar + 60 g lime. Analysis of variance results indicated different formulation of star fruit sorbet had significant effect (P<0.05) on colour, flavour, aroma, and overall but showed no difference on the texture of star fruit sorbet. Overall, the best formulation was 150 g sugar + 30 g lime juice with overrun score of 23.52%, pH 4.20, sugar content of 26.85 oBrix, melting time of 43.16 minutes, vitamin C content of 0.968 mg, and antioxidant activity of 320.86 ppm.

Environmental conditions caused by air pollution are so large that it impacts on changes in the ecosystem that affects all aspects of human life. Climate change is caused by increasing greenhouse gases in the earth's atmosphere because the Earth's atmosphere receives more carbon than it releases. This study aims to determine the potential of biomass and carbon uptake in mangrove stems in Pohorua village, Muna Regency. The research is quantitative descriptive, sampling using the Point Center Quarted Method (PCQM) technique measured around the height of the chest height mangrove tree (DBH). Data analysis was performed using an allometric equation in which each mangrove plant has a specific gravity. Carbon uptake found in mangroves stored in the roots, stems and leaves of mangrove plants, the results of the study showed that mangroves can absorb carbon quickly.

Rice Oryza sativa  L is a staple food crop, and its seeds are the most important component part of the agronomic trait of the cereal crop, rich in nutrient and of economic value to human and even livestock. But, it is often threatened by various abiotic and biotic conditions that reduce the yield, because of high incidences of infectious disease agents and non-pathogenic conditions respectively.

Lentil and chickpea are important winter legumes of Nepal. The experiments were carried out to evaluate the agronomic performance of lentil and chickpea genotypes at research field of Regional Agricultural Research Station (RARS), Bhagetada, Doti, Nepal during winter seasons of 2012 and 2013. The 16 lentil genotypes were evaluated in both years whereas 20 and 14 genotypes of chickpea were evaluated in 2012 and 2013 respectively. The genotypes were evaluated in a randomized complete block design with three replications. The results showed that both lentil and chickpea genotypes indicated differences for their morphological traits namely plant height, flowering, maturity, pods/plant and grain yield. The combined analysis of trials over years showed that lentil genotype namely Black Masuro produced the highest grain yield (790 kg/ha) followed by LG 12 (746 kg/ha) and ILL 3111 (747 kg/ha), respectively. Similarly, chickpea genotypes namely ICCX 840508-31 produced the highest grain yield (953 kg/ha) followed by ICCX 840508-40 (911 kg/ha) and BG 372 (850 kg/ha), respectively. It is suggested that the superior genotypes derived from these experiments could be further evaluated in farmers’ fields  before making recommendation for general cultivation
扁豆和鹰嘴豆是尼泊尔重要的冬季豆类。本试验于2012年和2013年冬季在尼泊尔多提省巴格塔达地区农业研究站(RARS)的研究基地对小扁豆和鹰嘴豆基因型进行了农艺性能评价。2012年和2013年分别对16个小扁豆基因型和20个鹰嘴豆基因型进行了评价。基因型评估采用随机完全区组设计,3个重复。结果表明,小扁豆和鹰嘴豆基因型在株高、开花、成熟度、荚果/株和籽粒产量等形态性状上存在差异。多年试验的综合分析表明,小扁豆基因型“黑马苏罗”的产量最高(790公斤/公顷),其次是LG 12(746公斤/公顷)和ILL 3111(747公斤/公顷)。同样,鹰嘴豆基因型ICCX 840508-31的籽粒产量最高(953公斤/公顷),其次是ICCX 840508-40(911公斤/公顷)和BG 372(850公斤/公顷)。建议通过这些试验获得的优良基因型可在农民田间进行进一步评价,然后再推荐普遍种植

The performance evaluation of maize genotypes  at a specific growing region is a key to crop improvement. The objectives of this study were to evaluate grain yield of maize genotypes at Bijayanagar (Mahatgaun VDC) and Tallo Lorpa (Dillichaur VDC), Jumla District of Nepal during spring seasons of 2012 and 2013. The maize genotypes were significant (P< 0.05) for grain yield, days to tasseling and silking and  disease scoring where as anthesis-silking interval, plant height and ear height were non significant. The pooled analysis of the results showed that the highest grain yield was produced by Ganesh-1 (4830 kg/ha) followed by KKT-POP (4408 kg/ha), KKT-14 (3952 kg/ha) and MGU-08 (3913 kg/ha, respectively. From this study, Ganesh-1, KKT-POP, KKT-14 and MGU-08 could be preferable choice for cultivation in Jumla district of Nepal.

Rice ( Oryza sativa  L.) is a cereal and staple food crop of over half of the world’s population. Blast, bacteria leaf blight and drought stresses affect yield of rice drastically ranging from 1-100% loss depending on the severity of disease and water deficit condition. Resistance and tolerance high yielding varieties of blast (Putra1) and drought (MR219 IR99784-156-137-1-3) respectively and also IRBB60 (bacteria leaf blight) were used. The research considered the genetic inheritance of the new improved lines and their interactions. Pedigree breeding method was used to develop two single, double and three-way (and reciprocal) crosses through marker-assisted selection. Southern blot analysis was used to determine success of introgression of resistance/tolerance genes/QTLs and selection, also validated by phenotyped results. Agro-morphological and yield parameters of the various populations were analysed. The results indicated levels of significant differences amongst and between treatments for non-drought stress (NS) and reproductive drought stress (RS) and their interactions. There were significant variation among parents and improved lines on some traits in NS treatment, but RS significantly affected parameters of DF, FFG, YM and most especially the susceptible parent, while the improved lines were tolerant.  Significant interactions was recorded (P≤0.05) between treatment and variety (Trt*Var.) on PL, T, FFG and GLW. Cluster analysis and PCA of relationship among the 9 traits in the two treatments revealed that each of single, double and three-way (and reciprocal) crosses had good lines either under NS and RS.
水稻(Oryza sativa L.)是世界上一半以上人口的谷物和主要粮食作物。稻瘟病、细菌性叶枯病和干旱胁迫对水稻产量的影响很大,损失幅度为1-100%,具体取决于病害的严重程度和缺水状况。选用抗、耐稻瘟病高产品种Putra1和抗旱高产品种MR219 IR99784-156-137-1-3和细菌叶枯病品种IRBB60。研究考虑了新改良品系的遗传及其相互作用。采用家系育种方法,通过标记辅助选择,培育出单、双、三向(和互惠)杂交组合。利用Southern blot分析确定抗性/耐受性基因/ qtl的渗入和选择是否成功,并通过表型结果进行验证。对不同居群的农业形态和产量参数进行了分析。结果表明,非干旱胁迫(NS)和生殖干旱胁迫(RS)处理之间及其相互作用水平存在显著差异。在NS处理下,亲本和改良系在某些性状上存在显著差异,但RS对DF、FFG、YM,尤其是易感亲本的参数影响显著,而改良系则具有耐受性。处理与品种(Trt*Var.)在PL、T、FFG和GLW上存在显著交互作用(P≤0.05)。聚类分析和主成分分析表明,单交、双交和三交(或互交)组合均能获得较好的品系。
