Abstract

Optimization conditions for thermostable xylanase production of Bacillus licheniformis TS10 by using substrate oil palm empty fruit bunches  has been conducted from November 2015 to January 2016 in the Laboratory of Genetics and Biotechnology, Department of Biology, Faculty of Mathematics and Natural Sciences, University of Sriwijaya, Indralaya. The aims of this study was to determine the potential of oil palm empty fruit bunches ( EFB ) as a substrate for the production of thermostable xylanase by Bacillus licheniformis TS10 and the optimum conditions of temperature, pH and substrate concentration in the fermentation process. The research method is to make the growth curve and the curve of Bacillus licheniformis TS10 enzyme production on EFB substrate. The number of bacterial cells was determined by using a UV-VIS spectrophotometer and total plate count (TPC) through a standard curve. Optimization performed at various pH (5, 6, 7, 8, 9), temperature (50 °C, 60 °C, 70 °C, 80 °C) and substrate (1%, 2%, 3%, 4%) , Test activity at each pH, temperature and substrate using methods DNS by measuring enzyme activity based on the reducing sugar released by the substrate by using dinitrosalicylic acid (DNS). Based on the results of this research showed that oil palm empty fruit bunches (EFB ) has potential as a substrate for the production of thermostable xylanase by Bacillus licheniformis TS10, thermostable xylanase production of Bacillus licheniformis TS10 on the substrate EFB has an optimum condition at pH 6, 80 °C and the substrate concentration of 4%.

Abstract

Culex spp are mosquito vectors that have a very wide distribution capability and are carriers of pathogens that can interfere with human and animal health. The wide distribution makes Culex spp a dangerous threat. DNA extraction is one of the important steps in obtaining genetic information and genetic analysis. Good quality DNA is used for activities such as the use of molecular markers, genome library creation, and sequencing. This study aims to determine the quality, concentration and purity of Culex spp mosquito DNA in Kemelak Bindung Langit Village, OKU Regency. It is hoped that the sample can be used for further research analysis on Mitochondria D-Loop Sequences in Culex spp mosquitoes. Quantitative measurement of DNA in the form of concentration and purity of DNA using Nanodrop Thermo cycle while qualitative DNA using electrophoresis technique. The results of the isolation of the mosquito genome DNA, obtained clear DNA bands without any degradation (smear) and the concentration results for the four samples ranged from 10-100 ng/µL and the DNA purity was good, ranging from 1.8 to 2.00.

Abstract

Jamur tiram putih (Pleurotus ostreatus) merupakan salah satu jenis jamur dari filum Basidiomycota yang mempunyai prospek sangat baik untuk dikembangkan dan memiliki nilai ekonomi yang tinggi, namun tidak semua petani jamur dapat menyiapkan bibit jamur sendiri. Oleh karena itu pengadaan bibit sendiri harus bisa dilakukan petani yang serius untuk berbisnis jamur tiram untuk mendapatkan keuntungan yang lebih besar. Belum terdapat petani yang menanam langsung jamur tiram langsung, umumnya petani menanam jamur tiram dari bibit yang dibeli atau dibuat sendiri. Oleh karena itu, penelitian ini bertujuan untuk menumbuhkan jamur tiram segar pada media PDA dan untuk melihat karakteristik pertumbuhan isolat jamur tersebut pada PDA, benih dan baglog. Penelitian ini dilakukan dengan menggunakan metode purposive sampling, sampel diambil di Desa Payakabung. Data hasil pertumbuhan inokulasi jamur tiram ke dalam botol dan pertumbuhan pada media baglog dilakukan dengan menggunakan Rancangan Acak Lengkap (RAL) diolah dengan bantuan program microsoft excel. Berdasarkan hasil penelitian tersebut didapatkan hasil bahwa isolasi yang dilakukan pada potongan tubuh buah jamur tiram segar dapat tumbuh dengan baik pada media PDA dan karakteristik pertumbuhan isolat PDA1 lebih lambat pertumbuhan miseliumnya dibandingkan dengan isolat PDA2. Kedua isolat memiliki koloni berwarna putih kecoklatan. Tidak ada perbedaan pertumbuhan kedua isolat jamur pada media benih yang disimpan pada suhu 20-25°C dan suhu 26-30°C pada media simpan benih. Pertumbuhan jamur tiram tumbuh dengan baik pada media kayu karet daripada kayu akasia.

Abstract

This article explores the use of directive speech acts in dialogues presented in English textbooks. Drawing on the theoretical framework of speech act theory by Parker and Riley (1994), the study focuses on understanding how directives—utterances that seek to influence the behavior of the listener—are presented in various dialogues. It examines the various forms and functions of directives, their role in communication, and how they help learners of English understand and practice practical conversational strategies. The article highlights the importance of directive speech acts in both formal and informal contexts, with specific examples drawn from English language textbooks. This study uses qualitative descriptive research where data is found in dialogues in textbooks and then matched with theory and poured into a sentence. This study found that there are five types of directive speech acts, namely, orders, warnings, giving advice, suggestions, and recommendations. In this study, 7 command data, 3 warning data, 2 advice data, 8 suggestion data, and 1 recommendation data were found. In this study, two techniques were found in the delivery of speech acts, namely direct and non-direct. Non-direct techniques tend to contain an element of politeness rather than direct. In addition, the speech actions in this textbook can help students understand, and using directive speech acts effectively can significantly improve communicative competence in language learners.

Abstract

The problems that hit the global community raise concern. Classical problems such as poverty, hunger, and access to education are other complicated issues that drive leaders to express their commitment to transforming the world through sustainable development goals. Zakat refers to the social responsibility of the Muslim community toward the universal humanitarian mission and the natural environment as a concern of global leaders. The main goal of bibliometric research is to analyze and measure patterns of scientific publications, the distribution of literature, and the development of research. The article data indexed by Scopus and downloaded is the year of publication, the author's name and affiliates, keywords, and geographical distribution. Based on the Scopus database of 23 documents related to the prospects of Zakat in a Sustainable Economy published in the period 2014-2023 and data analyzed using VOSviewer software, The growth trend of the highest Scopus-indexed Sustainable Economy publication reached 5 publications in 2022 and 2023. This research contributes to the literature related to this theme as well as researchers interested in exploring this field. The research results show that there are still very few publications in this field, so researchers are exploring this theme further.

Abstract

Tujuan dalam penelitian ini adalah kapasitas belajar merupakan elemen krusial dalam pendidikan karena menentukan kemampuan peserta didik dalam menyerap, mengolah, dan mengaplikasikan pengetahuan secara efektif. Dalam konteks pendidikan dasar Islam, kapasitas belajar memiliki peran penting dalam membentuk generasi yang tangguh secara intelektual dan spiritual. Namun demikian, belum banyak penelitian yang mengkaji secara mendalam prinsip-prinsip umum kapasitas belajar dalam perspektif Islam serta relevansinya dalam pengembangan kurikulum dan strategi pembelajaran. Penelitian ini menggunakan pendekatan kualitatif dengan metode kajian pustaka yang menganalisis sumber-sumber ilmiah internasional dan nasional terkait kapasitas belajar dan pendidikan dasar Islam. Hasil penelitian menunjukkan bahwa kapasitas belajar dalam Islam mencakup integrasi dimensi kognitif, afektif, spiritual, dan sosial yang selaras dengan nilai-nilai keislaman. Temuan ini mengindikasikan perlunya pembaruan kurikulum dan strategi pembelajaran agar mampu menumbuhkan kemampuan berpikir reflektif, motivasi intrinsik, serta karakter belajar mandiri pada peserta didik. Penelitian ini juga menyoroti pentingnya peran pendidik dalam membangun kapasitas belajar melalui pembelajaran yang kontekstual dan transformatif. Implikasi dari penelitian ini memperluas pemahaman konseptual dan menawarkan model pendidikan dasar Islam yang lebih integratif dan adaptif terhadap tantangan zaman
