The experiment aimed to induction of insensitive peanut somatic embryo (SE) to culture filtrate medium from various races of S. rolfsii and its plantlet regeneration. To achieve these objective, the experiments have been done in several steps: somatic embryo development, preparation of culture filtrate (CF) medium from various races of S. rolfsii, induction of insensitive peanut somatic embryo and peanut plantlet regeneration of insensitive somatic embryo. Result of experiment showed that selected SEs on selective medium containing culture filtrate of S. rolfsii one race or two races or three races or four races were specifically insensitive only on selective medium containing culture filtrate one race or two or three or four races of S. rolfsii. All SEs selected in culture filtrate medium of four races S. rolfsii (race 1, 6, 8, and 9) were more insensitive on culture filtrate medium of S. rolfsii races compared with SEs that only selected in culture filtrate medium of one race. Selected insensitive SEs had ability to form normal seedling (50.5-65.5%) and abnormal germinated SEs (23.5 - 30.5%). Normal germinated SEs developed to form plantlets. These plantlets were developed to produced peanut plant R1 generation and peanut seeds. Further evaluation using subsequent generation of peanut (R1 and R2) plants need to be conducted to testing peanut line resistance to stem rot disease (S. rolfsii) in the field.The experiment aimed to induction of insensitive peanut somatic embryo (SE) to culture filtrate medium from various races of S. rolfsii and its plantlet regeneration.

The effect of grain mass variations on drying time by adding a pipe heat exchanger to a fluidized bed dryer 通过在流化床干燥器中加入管式换热器,研究了颗粒质量变化对干燥时间的影响
Syahrul, A. Cahyono, M. Mirmanto, H. S. Tira, Sukmawaty, G. Putra
Drying is one way of post-harvest handling to extend the shelf life, especially for agricultural crops. In general, post-harvest drying is only done naturally by using heat from solar energy or commonly called conventional drying. In this study, the grain was dried using a fluidized bed dryer. However, the fluidized bed dryer was modified by adding a pipe heat exchanger. The purpose of this study was to find the effect of grain mass and air intake temperatures on drying time. The Indonesian government has carried out SNI provisions for milling the maximum water content in the material which is 14%. In this study, the grain used was the newly harvested grain where the water content was about 20% with a tolerance of ± 1%. The mass variations in this study were 0.4 kg, 0.6 kg and 0.8 kg and the temperature variations applied were 55°C, 60°C, and 65° C. The results showed the highest heat loss occurs at the highest mass because the air velocity is not able to circulate properly.Drying is one way of post-harvest handling to extend the shelf life, especially for agricultural crops.

干燥是收获后处理延长保质期的一种方法,特别是对农作物。一般来说,收获后的干燥只能通过利用太阳能的热量自然完成,或者通常称为常规干燥。在本研究中,使用流化床干燥器对谷物进行干燥。然而,流化床干燥器通过增加管式换热器进行了改进。本研究的目的是找出籽粒质量和进风温度对干燥时间的影响。印尼政府已执行SNI规定,研磨材料中的最大含水量为14%。在本研究中,使用的谷物为新收获的谷物,含水量约为20%,公差为±1%。本研究的质量变化为0.4 kg, 0.6 kg和0.8 kg,应用的温度变化为55°C, 60°C和65°C。结果表明,由于空气速度不能正常流通,最大的热损失发生在最大的质量处。干燥是收获后处理延长保质期的一种方法,特别是对农作物。一般来说,收获后的干燥只能通过利用太阳能的热量自然完成,或者通常称为常规干燥。在本研究中,使用流化床干燥器对谷物进行干燥。然而,流化床干燥器通过增加管式换热器进行了改进。本研究的目的是找出籽粒质量和进风温度对干燥时间的影响。印尼政府已执行SNI规定,研磨材料中的最大含水量为14%。在本研究中,使用的谷物为新收获的谷物,含水量约为20%,公差为±1%。本研究的质量变化为0.4 kg, 0.6 kg和0.8 kg,应用的温度变化为55°C, 60°C和65°C。结果表明,由于空气速度不能正常流通,最大的热损失发生在最大的质量处。

Effect of solid and liquid extract of Sargassum crassifolium on growth and yield of rice plant 马尾草固体和液体提取物对水稻生长和产量的影响
E. Prasedya, Brigitta A. F. D. Geraldine, Nurul Noviandi Nahdia Putri, A. S. Abidin, A. Jupri, H. Sunarpi
The excessive use of ingonaic fertililizer in agriculture system production reduces soil fertility and polluted out environment. Therefore, the use of organic ferlizer is increased recently. Many authors report that macroalgae is an important source of organic biostimulant and biofertilizer. This is due to the fact that liquid extract contains phytohormone, and solid extract contains essential elements, stimulating growth and production of plants. This article reports effect of solid and liquid extracts on growth and yield of rice plants. Liquid extract (10%) was sprayed during vegetative growth of the plants. On the other hand, liquid extract (5%) was applied directly to growth media. Then, the growth parameters (plant height, tiller number, shoot dry weight and root dry weight), and yield parameters (penicle number and grain weight), were measured during harvesting time. The results show that solid and liquid extracts of Sargassum crassifolium increased the growth and yield of rice plants. This indicates that solid extract of Sargassum crassifolium could be developed as a source of organic fertilizer. On the other hand, liquid extract of Sargassum crassiflium could also be used as a source of organic biostimulant. Both products should support suitable agriculture production.The excessive use of ingonaic fertililizer in agriculture system production reduces soil fertility and polluted out environment.

农业系统生产中过量使用无机肥料,降低了土壤肥力,污染了环境。因此,近年来有机肥的使用量有所增加。许多作者报道,大型藻类是有机生物刺激素和生物肥料的重要来源。这是由于液体提取物含有植物激素,而固体提取物含有必需元素,刺激植物生长和生产。本文报道了固体提取物和液体提取物对水稻植株生长和产量的影响。在植株营养生长期间喷洒10%的液体提取物。另一方面,液体提取物(5%)直接施用于生长培养基。然后,在收获期间测量生长参数(株高、分蘖数、茎干重和根干重)和产量参数(青霉数和粒重)。结果表明,马尾草固体提取物和液体提取物对水稻的生长和产量都有促进作用。这表明马尾藻固体提取物可开发为有机肥的一种来源。另一方面,马尾藻液体提取物也可作为有机生物刺激素的来源。这两种产品都应该支持适当的农业生产。农业系统生产中过量使用无机肥料,降低了土壤肥力,污染了环境。因此,近年来有机肥的使用量有所增加。许多作者报道,大型藻类是有机生物刺激素和生物肥料的重要来源。这是由于液体提取物含有植物激素,而固体提取物含有必需元素,刺激植物生长和生产。本文报道了固体提取物和液体提取物对水稻植株生长和产量的影响。在植株营养生长期间喷洒10%的液体提取物。另一方面,液体提取物(5%)直接施用于生长培养基。然后,在收获期间测量生长参数(株高、分蘖数、茎干重和根干重)和产量参数(青霉数和粒重)。结果表明,马尾草固体提取物和液体提取物对水稻的生长和产量都有促进作用。这表明…

Our previous finding showed that the single culture of Lactobacillus plantarum has a maximum time of 18 hours in order to produce carboxyl cellulose and amylase during cassava fermentation. These two enzymes are important in order to give a final characteristic of modified cassava flour including texture, aroma, flavor and taste. The cyanide content of cassava tuber also decreases during its fermentation process. We therefore aimed to modify the starter using co-culture starter of L. plantarum and L. acidophilusand to analyze the production of extracellular amylase and carboxymethyl cellulose during cassava fermentation. The maximum of carboxymethyl cellulose and amylase activity of 13.76 × 10−3 U/ml and 8.31 × 10−3 U/ml, respectively, were obtained from filtrate that has been incubated at 37°C for 23 and 26 h, respectively under static condition. The Km of CMCase and amylase by co-culture starterof L. plantarum and L. acidophilus (1:1) were 0.4791 × 10−3 U/ml and 0.6133 × 10−3 U/ml, respectively.

我们之前的研究表明,在木薯发酵过程中,植物乳杆菌单次培养最多需要18小时才能产生羧基纤维素和淀粉酶。这两种酶对于决定改性木薯粉的质地、香气、风味和口感至关重要。木薯块茎的氰化物含量在发酵过程中也有所降低。因此,我们旨在利用植物乳杆菌和嗜酸乳杆菌共培养发酵剂对发酵剂进行改良,以分析木薯发酵过程中胞外淀粉酶和羧甲基纤维素的产生。在37℃静态培养23 h和26 h的滤液中,羧甲基纤维素和淀粉酶活性的最大值分别为13.76 × 10−3 U/ml和8.31 × 10−3 U/ml。植物乳杆菌与嗜酸乳杆菌(1:1)共培养发酵剂对CMCase和淀粉酶的Km分别为0.4791 × 10−3 U/ml和0.6133 × 10−3 U/ml。CMCase和淀粉酶的Vmax分别为0.8902 × 10−3和0.8703 × 10−3 g/mL。您之前的研究结果表明,在木薯发酵过程中,植物乳杆菌单次培养产生羧纤维素和淀粉酶的时间最长为18小时。这两种酶对于决定改性木薯粉的质地、香气、风味和口感至关重要。木薯块茎的氰化物含量在发酵过程中也有所降低。因此,我们旨在利用植物乳杆菌和嗜酸乳杆菌共培养发酵剂对发酵剂进行改良,以分析木薯发酵过程中胞外淀粉酶和羧甲基纤维素的产生。在37℃静态培养23 h和26 h的滤液中,羧甲基纤维素和淀粉酶活性的最大值分别为13.76 × 10−3 U/ml和8.31 × 10−3 U/ml。植物乳杆菌与嗜酸乳杆菌(1:1)共培养发酵剂对CMCase和淀粉酶的Km分别为0.4791 × 10−3 U/ml和0.6133 × 10−3 U/ml。Vmax fo……

The effect of expired bread supplementation in local sheep rations on rumen fermentability and digestibility value in vitro 地方羊口粮中添加过期面包对瘤胃体外发酵和消化价值的影响
A. Hanifa, S. D. Widyawati
This study aims to determine the effect of expired bread supplementation on sheep rations in digestibility and rumen fermentability in vitro. The study used a Compeletely Randomized Design (CRD) with 4 treatments and 3 replications. The first treatment P0 was a control, sheep fed with 100% basal concentrates. The second treatment P1, sheep fed with 95% basal concentrates plus 5% expired bread. The third treatment P2, sheep fed with 90% basal concentrates plus 10% expired bread. And the last treatment P3, sheep fed with 85% basal concentrates plus 15% expired bread. Data collected were rumen pH, concentration of NH3 (mM), digestibility of dry matter and organic matter (%). The result showed that feed treatments didn’t significantly affect (P>0.05) on rumen pH, concentration of NH3, digestibility of dry matter and organic matter. The average of rumen PH of treatment P0, P1, P2 and P3 respectively was 6.84; 6.86; 6.82 and 6.87. The average of concentration of NH3 of treatment P0, P1, P2 and P3 respectively was 16.17; 16.07; 13.52 and 16.62 mM. The average of dry matter digestibility of treatment P0, P1, P2 and P3 respectively was 51.76; 53.01; 52.16 and 54.71%. The average of organic matter digestibility of treatment P0, P1, P2 and P3 respectively was 53.16; 55.82; 52.24 and 57.59%. It was concluded that expired bread supplementation at the level of 15% can be used to replace basal concentrates in feed male local sheep.This study aims to determine the effect of expired bread supplementation on sheep rations in digestibility and rumen fermentability in vitro.

Coral Echinoporalamellosa hosts multiple clades of symbionts in Western Alas Strait, Indonesia 在印度尼西亚的西阿拉斯海峡,Echinoporalamellosa珊瑚拥有多个共生体分支
Imam Bachtiar, M. Ghafari, I. Rahman, B. Hilda, Mahrus
Coral symbiont diversity is one of the most important factors in coral resistance and coral reef resilience to bleaching. Many corals host only one symbiont clade, thus many of them vulnerable to climate change induced bleaching. Corals in Alas Strait have survived from several bleaching events. The present study aimed to look at genetic factors that potentially contributed to the survival of Echinoporalamellosa coral. Previously, E. lamellosawas reported to host only one clade of symbiont, either in Pacific or Indian Oceans. Here we provide new evidence on the ability of E. lamellosain hosting multiple clades of symbionts. The symbiont rDNA was extracted from small E. lamellosafragments and amplified by targeting ‘the non-coding gene region’ of ITS1-5.8S-ITS2. The clustering technique was used to determine the clade type of symbiont, by constructing the phylogenetic tree consist of the sequenced samples and downloaded sequences from GenBank NCBI as comparison. The constructed phylogenetic tree was based on Maximum Likelihood (ML) with bootstrap value 1000× to get the best result. The result shows the symbiont in E. lamellosatissue belonged to clades B and C. The combination of the two symbiont clades has never been recorded in previous studies, and it is very likely to have contributed to coral survival from bleaching events.Coral symbiont diversity is one of the most important factors in coral resistance and coral reef resilience to bleaching.

珊瑚共生多样性是影响珊瑚抗白化能力和珊瑚礁抗白化能力的重要因素之一。许多珊瑚只拥有一种共生枝,因此许多珊瑚容易受到气候变化引起的白化的影响。阿拉斯海峡的珊瑚从几次白化事件中幸存下来。目前的研究旨在研究可能影响棘孔藻存活的遗传因素。以前,据报道,在太平洋或印度洋中只有一个共生体的分支。在此,我们提供了新的证据,证明了薄叶藻寄主多个共生体分支的能力。从大肠杆菌的小片段中提取共生体rDNA,并针对ITS1-5.8S-ITS2的“非编码基因区”进行扩增。利用聚类技术,将测序样本与从GenBank NCBI下载的序列进行比对,构建系统发育树,确定共生体的枝型。构建的系统发育树基于最大似然(ML), bootstrap值为1000x,以获得最佳结果。结果表明,在E. lamellosatissue中,共生体属于B枝和c枝。这两个共生体枝的结合在以往的研究中从未被记录过,很可能对珊瑚在白化事件中存活做出了贡献。珊瑚共生多样性是影响珊瑚抗白化能力和珊瑚礁抗白化能力的重要因素之一。许多珊瑚只拥有一种共生枝,因此许多珊瑚容易受到气候变化引起的白化的影响。阿拉斯海峡的珊瑚从几次白化事件中幸存下来。目前的研究旨在研究可能影响棘孔藻存活的遗传因素。以前,据报道,在太平洋或印度洋中只有一个共生体的分支。在此,我们提供了新的证据,证明了薄叶藻寄主多个共生体分支的能力。从大肠杆菌的小片段中提取共生体rDNA,并针对ITS1-5.8S-ITS2的“非编码基因区”进行扩增。利用聚类技术,将测序样本与从GenBank NCBI下载的序列进行比对,构建系统发育树,确定共生体的枝型。构建的系统发育树基于…

Logistic model of abalon’s length growth in Sekotong, West Lombok 西龙目岛Sekotong地区鲍鱼长度增长的Logistic模型
Marliadi Susanto, M. U. Romdhini, S. Kamali, Laya Zurfani
Abalon (Haliotisasinina) is a marine animal that is classified in shellfish and belongs to the class of gastrophoda, family haliotidae. It is one of the mainstays of NTB and national ethnofauna as marine commodities for export. The existence of these snails has provided an important role for the economy of coastal communities not only eaten or sold in the local market but also exported to several Asian countries, Europe and the United States. Thus, the growth of Abalone is very important to know quickly so that the process of abalone cultivation becomes more effective. Abalone growth is a logistical problems, Abalone growth can be observed through changes in weight, length and biomass. this study focused on the growth of abalone length as a continuation of previous research. The length of Abalone is also one of the parameters of successful cultivation and marketing. It should be noted that knowing the growth of Abalone is quiteslows so this also becomes an interesting phenomenon to study. Slow growth is certainly one of the economic problems because it is related to the time of marketing or harvesting. One way to know quickly the growth of abalone is to construct the mathematical modelso that based on the results of analyzing the model can be known the optimal length and time of harvesting. The mathematical model constructed in this case is the Von Berlatanffy model as a generalization of the Verhulst logistics model. Based on the results of analysis of the model obtained the growth of the length of the Abalone reaches a maximum of 12 cm at the age of 80 months. However, harvesting at that age is less effective because it will require more maintenance costs so that the optimal harvesting time is 26 months with an abalone length of 8 cm and the length is said to be the optimal length because it meets national or international market standards.Abalon (Haliotisasinina) is a marine animal that is classified in shellfish and belongs to the class of gastrophoda, family haliotidae.

鲍鱼(balalon)是一种贝类动物,属于腹足纲,鲍鱼科。它是国家海洋出口商品和民族动物的支柱之一。这些蜗牛的存在为沿海社区的经济提供了重要的作用,不仅在当地市场上食用或销售,而且还出口到几个亚洲国家、欧洲和美国。因此,快速了解鲍鱼的生长情况对提高鲍鱼养殖的效率具有重要意义。鲍鱼的生长是一个物流问题,鲍鱼的生长可以通过体重、长度和生物量的变化来观察。本研究的重点是鲍鱼长度的增长,作为以往研究的延续。鲍鱼的长度也是成功养殖和销售的参数之一。值得注意的是,鲍鱼的生长非常缓慢,所以这也成为一个有趣的研究现象。生长缓慢当然是经济问题之一,因为它与销售或收获的时间有关。快速了解鲍鱼生长情况的一种方法是建立数学模型,根据模型分析结果确定最佳采收时长和采收时间。在这种情况下建立的数学模型是Von Berlatanffy模型作为Verhulst物流模型的推广。根据模型的分析结果,鲍鱼的体长在80月龄时达到了12厘米的最大值。然而,在这个年龄采收效果较差,因为它需要更多的维护成本,所以最佳采收时间为26个月,鲍鱼长度为8厘米,据说这是最佳长度,因为它符合国家或国际市场标准。鲍鱼(balalon)是一种贝类动物,属于腹足纲,鲍鱼科。它是国家海洋出口商品和民族动物的支柱之一。这些蜗牛的存在为沿海社区的经济提供了重要的作用,不仅在当地市场上食用或销售,而且还出口到几个亚洲国家、欧洲和美国。因此,快速了解鲍鱼的生长情况对提高鲍鱼养殖的效率具有重要意义。鲍鱼的生长是一个物流问题,鲍鱼的生长可以通过体重、长度和生物量的变化来观察。本研究的重点是鲍鱼长度的增长,作为以往研究的延续。鲍鱼的长度也是成功养殖和销售的参数之一。值得注意的是,鲍鱼的生长非常缓慢,所以这也成为一个有趣的研究现象。缓慢的增长是c…
