Identification of Quantitative Trait Loci Determining Vegetative Growth Traits in Coffea Canephor

Recently the use of molecular markers has been successfully applied for some crops. For coffee, new opportunities have been opened since Nestlé R&D Centre in collaboration with ICCRI completed the first genetic map of Coffea canephora. This study was aimed both to evaluate the phenotypic trait and also to identify the quantitative trait loci (QTLs) controlling the vegetative growth in Robusta coffee. Present study used three C. canephora populations and six genetic maps developed based on these populations using simple sequence repeats (SSRs) and single nucleotide polymorphisms (SNPs) markers. A total of 17 different quantitative data were used for the detection of QTLs on each of three populations. Present result showed that most of these traits were not heritable. The nine vegetative traits have been identified and distributed over seven different linkage groups. Due to some QTLs determining one given trait were overlapping on the same linkage group and were coming from the same favourable parent, a total of 19 QTLs detected for vegetative traits might finally be considered as only 12 QTLs involved. However, only two of them were shared for different traits. One involved for the number/length of primary branches and width of the canopy while the other for length of internodes and width of canopy. These two QTLs might determine the size of the tree canopy in this species

PERBANDINGAN PENGGUNAAN METODE NUMBERED HEADS TOGETHER (NHT) DENGAN METODE STUDENT TEAMS ACHIEVEMENT DIVISION (STAD) TERHADAP HASIL BELAJAR MATEMATIKA Di SMP Negeri 8 Kota Cirebon

Ucu Satriah ( 58451048 ): Perbandingan Penggunaan Metode Numbered Heads Together (NHT) Dengan Metode Student Teams Achievement Division (STAD) Terhadap Hasil Belajar Matematika Di Smp Negeri 08 Kota Cirebon” Sejauh ini proses pembelajaran yang dilakukan di sekolah-sekolah khususnya pada mata pelajaran matematika masih menggunakan metode konvensional yang bersifat teacher centered, yaitu pembelajaran yang berpusat pada guru, belum bisa mengembangkan aktivitas positif siswa yang mendukung proses pembelajaran. Tujuan dari penerapan pembelajaran ini yaitu untuk menciptakan ikatan yang kuat antar siswa, membangun kecerdasan sosial dan emosional, sehingga pada akhirnya siswa bisa berinteraksi terhadap lingkungannya dengan segala kemampuan dan potensi diri yang berkembang dengan baik dan menjadikan siswa sebagi pusat pembelajaran sehingga siswa dapat bertukar informasi dan pendapat satu sama lainnya. Salah satu alternatif pembelajaran yang dapat meningkatkan aktivitas positif siswa dan hasil belajar siswa adalah metode Numbered Heads Together ( NHT ) dan metode Student Teams Achievement Division ( STAD ). Metode Numbered Heads Together (NHT) merupakan metode belajar kelompok yang diawali dengan pemberian nomor kepada setiap anggota kelompok dengan setiap kelompoknya terdiri dari 3-6 orang anggota, dan nomornomor tersebut yang akan menjadi identitas siswa dalam proses pembelajaran. Sedangkan metode Student Teams Achievement Division (STAD) merupakan metode belajar kelompok yang beranggotakan 4 – 5 orang yang dibentuk dari anggota yang heterogen terdiri dari laki-laki dan perempuan yang berasal dari berbagai suku, yang memiliki kemampuan tinggi, sedang dan rendah. Hasil penelitian yang diperoleh dari postes, untuk kelas VIII B memperoleh skor rata-rata sebesar 14,22 dengan nilai rata-ratanya sebesar 71,10 dan termasuk dalam kategori tinggi. Sedangkan untuk kelas VIII E memperoleh skor rata-rata sebesar 14,09 dengan nilai rata-ratanya 70,45 dan termasuk dalam kategori tinggi.

Whereas self-regulated learning is an absolute requirement of the success of distance students. One of the distance education characteristics is the separation of place and time among teachers and learners. To overcome these obstacles distance institution provides learning assistance services for its students in the form of online tutorials. Therefore, this study developed an online tutorial that integrates self-learning strategies that refer to the learning guide book "CERDAS Strategy for science distance education students". This guidance emphasizes on strategies of selecting and applying learning methods, managing time and learning environment, maintaining learning motivation, and doing self evaluation/ self reflection. The aim of this study is to analyze the benefits of the application of self-regulated learning guides integrated with online tutorials (PBTO) on improving student self-regulation and achievement. The method of the ressearch is mixed method research with embedded experimental design. Research respondents are students who follow online tutorials in Strategy of Biology Learning Course, Evaluation of Biology Learning, Animal Development, and Human Anatomy and Physiology in the semester of 2015/2016 in one of distance education in Indonesia. The data were collected using several instruments, namely the scale of self regulated learning, test, observation sheet, questionnaire, and interview. The scale of self regulated learning, observation sheets, questionnaires, and interviews were validated by experts. The scale of learning independence was also tried out. The item test was standardized and obtained from the distance education item bank. Data were analyzed quantitatively and qualitatively. The results show that the implementation of PBTO improve students’ independent learning and achievement. Particularly, firstly, the study guide integrated with online tutorials significantly improve total students’ self regulated learning in the low category. However, it increased students’ self-regulated learning in the moderate category for some aspects, those are, time management and self-evaluation. It increased students’ self-regulated learning in the low category for other aspects such as strategic planning, self-regulation, learning environment management, self-reaction, motivation, self-efficacy, goal setting, strategic planning in science.; Secondly, PBTO improve students achievement in the moderate category; thirdly, in addition to aspects of self-regulated learning, activity students and tutors affected the students' self-regulated learning, and fourth, the independence of learning is positively correlated to the success of student study

Impact of Long Dry Season on Bean Characteristics of Robusta Coffee (Coffea Canephora)

Bean characteristics in Robusta coffee (Coffea canephora) should be taken into considerations in coffee breeding. Beside genetic factor, environment has been known as an important factor in the formation and change of composition of bean characteristics. This research aimed to find out the effect of long dry season on changes of bean characteristics. The population observed consisted of 277 genotypes originated from reciprocal crossings of three parental namely BP 409, BP 961 and Q 121. Observation was conducted in Kaliwining Experimental Garden of ICCRI in Jember, East Java during two years with different drought intensity i.e. 2005—2006 and 2006—2007 production years. The result showed that long dry season decreased the range value of population of normal beans, pea beans and triage beans, and followed by decreasing in the mean value except for normal beans. Long dry season also influence the change of value range of empty bean to higher proportion, and followed by increasing in the mean value. Distribution pattern of normal beans tend in to remain at high proportion, in contrast to those of pea and triage beans. In other side, long dry season tended to change distribution pattern of empty beans to at high proportion. Correlation analysis among beans characteristics showed that normal beans had negative correlations with pea beans and empty beans. Pea beans had a positive correlation with empty beans. Long dry season decreased proportion of pea bean and triage bean, in contrast to those of empty beans. Increasing proportion of empty bean was caused by failure of growth to normal bean under stress condition

Signs of Dystopia and Demoralization in global academia: Reflections on the precarious and destructive effects of the colonization of the Lebenswelt

This document is the Accepted Manuscript version of the following article: Mike Geppert, Graham Hollinshead, (2017) "Signs of Dystopia and Demoralization in global academia: Reflections on the precarious and destructive effects of the colonization of the Lebenswelt", Critical perspectives on international business, Vol. 13(2): 136-150, May 2017, doi: 10.1108/cpoib-07-2016-0026. Published by Emerald Group Publishing Limited.Purpose Our paper has been written in the style of a provocative essay. It starts with the observation that neo-liberalism has become the leading “policy doctrine” in Higher Education (HE) systems across the globe. This has put increasing systemic political and economic pressure on many universities which not only undermine but also “colonize” the Lebenswelt or “lifeworld” (Habermas, 1987) of academics. Design/methodology/approach Our essay draws on concrete empirical examples based on our subjective experiences within the higher educational sector and secondary sources. Findings We are going to highlight and illustrate how the increasing dominance of “neo-liberal science” principles (Lave et al., 2010) severely damage the quality of knowledge production and working conditions of ordinary academics in both national and international academic communities. Practical implications Our essay provides insights into the practical implications of the spread of “neo-liberal science” principles on the work and employment of academics. Originality/value We aim to trigger critical discussion concerning how emancipatory principles of teaching and research can be brought back into the Lebenswelt of academics in order to reverse some of the destructive effects to which our essay refers to.Peer reviewedFinal Accepted Versio

Variation of Potential Yield of Hybrid Population of Robusta Coffee (Coffea Canepor

The low yield of Robusta coffee in Indonesia may be due to the use of planting materials derived from seeds. The research objective was to determine the variation of Robusta coffee yield wich local propagated by using seeds. The study was conducted in Kaliwining experimental Station of ICCRI (Indonesian Coffee andCocoa Research Institute). There were two populations observed. Number of progeny used in this study were 186 genotypes consisting of two groups from crossesBP 409 x Q 121 with 89 progenies and BP 961 x BP 409 with 81 progenies. The results showed that planting materials from seeds exhibit properties mixed results.Progeny that have the best results (yield more than 2 ton/ha) not more than 5% of the total population. In both populations there is a big difference between the progenythat has high and low yield. Highest yield B population could reach 2,500 kg/ha and the C population reached 2,200 kg/ha. The lowest yield can only produce coffee270 kg/ha in populations B and 120 kg/ha in population C

Analysis of Cutting Growth Characteristics in Robusta Coffee(Coffea Canephora Pierre.)

Development of Robusta coffee clones needs special characteristics for rootstock. This research was aimed to study the characteristics of cutting growth of Robusta coffee as influenced by genetic factor. The research was conducted at Indonesian Coffee and Cocoa Research Institute using 269 progenies originated from reciprocal crossing populations among three parentals, namely BP 409, BP 961, and Q 121. BP 308 an easy cutting-propagated genotype was used as control. The research was arranged in three replications of randomized completely block design with 10 cuttings per replication. Each cutting was single planted in plastic polybag of 15 cm x 25 cm without any growth-regulator treatment. Cluster analysis procedure showed root growth characteristics which could be divided into three groups namely easy (85.3%, 3.82 and 6.68 cm), moderate (57.6%, 1.73 and 4.01 cm) and difficult (25.1%, 0.58 dan 1.44 cm) based on proportion of rooted cuttings, number of primary root and length of root, respectively. On the other side, growth of sprout showed good homogenous characteristic, mainly indicated by proportion of sprouted cuttings which generally achieved up to 98% in average. Study on shoot-root ratio of cuttings resulted in two groups of progenies, namely the first which tended to be dominant on sprout growth and the second which tended to balance their root and sprout growth. Based on proportion of sprouted cuttings which almost achieved up to 100% and various proportion of rooted cutting, it could be indicated that growth of cuttings was started and dominated by the growth of sprout
