Amorphophallus muelleri Blume synonym of A. oncophyllus (porang) is one of the species of porang that grows in Indonesia, especially in East Java. It has a high economic value because the tubers contain glucomannan. Earlier work reported that harvest timing and length of storage affected secondary metabolite containing on plants. The study objective was to determine the glucomannan content of porang at 1, 2 months before dormant, at dormant and length of storage time (1 and 2 months after dormant) at room temperature. Glucomannan was isolated from fresh tubers to easier removal of the impurities and obtain the high purity of glucomannan. The highest obtained glucomannan was determined its functional groups using Fourier Transform Infrared (FTIR). The highest glucomannan content was derived in tubers taken at dormant compared to before and after dormant. FTIR spectra confirmed the presence of functional groups that compose the glucomannan compound.
Problems that are often encountered in career planning are students who choose the wrong career because they are forced to follow the wishes of their parents so that careers that are in accordance with the child's wishes, talents, and abilities are ignored. The intervention of parents who tend to dominate their desires in children's studies is considered the right decision, while children are considered still unable to determine attitudes and make decisions to plan their careers. Some of the difficulties that arise during the job search process often occur because individuals do not have a clear career planning direction. In addition, job providers are also more selective in finding and selecting prospective employees. The purpose of this study is to determine whether the use of career tree-based information services can improve students' understanding of career planning or not. This study uses quantitative research with a Quasi-Experimental design experimental research method. The Quasi-Experimental form used in this study is the Pretest Posttest Group Design with a sample of 35 people. The instrument used in this study used a Likert scale model. The results showed that career tree-based information services can improve students' understanding of career plans. Students can understand clearly and with a strong passion to determine their own career by referring to various information obtained through the career
The Cohesion of discourse is divided into two aspects, namely grammatical Cohesion, and lexical Cohesion. In this study, what will be examined is lexical Cohesion. This study aims to identify forms of lexical Cohesion in the text of the speech of German Prime Minister Angela Merkel. Text analysis of this speech uses Halliday and Hasan's cohesion theory. This research is qualitative. The design in this study is content analysis with descriptive characteristics, namely the presentation of data based on the object of research. The data observed were all lexical elements in cohesive words, phrases, clauses, and sentences. The results showed the percentage of use of lexical Cohesion included (1) 37% repetition; (2) synonymy 8%; (3) hyponymy 7%; (4) receives 2%; (5) antonymy 46%. The data shows that the lexical antonym is the most dominant lexical type found in Angela Merkel's speech text.
Makroalga merupakan sumber daya hayati laut yang memiliki nilai ekonomis penting yang dimanfaatkan sebagai bahan makanan dan obat-obatan. Penelitian ini dilaksanakan di Perairan Desa Langara Bajo Konawe Kepulauan yang bertujuan untuk menggetahui Struktur Komunitas Makroalga, seperti indeks keanekaragaman, indeks keseragaman, indeks dominansi, dan pola sebaran makroalga. Penelitian ini dilaksanakan pada bulan April-Mei 2018, yang meliputi pengambilan data dan penggolahan data penelitian. Pengambilan data dilakukan dengan metode transek kuadrat. Pengambilan data di setiap stasiunnya dilakukan sebannyak 3 kali. Jenis makroalga yang diperoleh yaitu Halimeda opuntia, Neomeris vanbosseae, Valonia fastigiata, Dictyosphaeria cavernosa, Halimeda discoidea, Halimeda tuna, Halimeda macrobola, Ceulerpa serrulata, Chlorodesmis fastigiata, Turbinaria ornota, Dictyota bartayresiana, Padina australis, Sargassum polycystum, Amphiroa fragilissima, Glacilaria cotoni, Acanthopora spicifera, Laurencia tronai, dan Glacilaria salicornia. Indeks keanekaragaman jenis makroalga (H’) berkisar antara 0,748−2,182, indek keseragaman (E) berkisar antara 0,477−0,878, indeks dominansi (D) berkisar antara 0,144−0,581, pola sebaran (Id) berkisaran antara 0,705−2,903 termasuk kategori merata dan mengelompok. Substrat pada lokasi penelitian bertekstur pecahan karang dan pasir.Kata Kunci: Struktur Komunitas, Makroalga, Perairan Desa Langara Bajo.
This study aims to examine the effect of motivation, physical work environment, non-physical work environment and job satisfaction on performance. A total of 63 respondents from Non-permanent Employees in the Regional Government of Ternate were surveyed in this study. The analytical tool used in this study is regression analysis. The results showed that of the four hypotheses proposed in this study, only hypothesis 1 was unsupported. Furthermore, at the end of the research results are discussed in this study.
