Pengaruh Negatif Stunting terhadap Perkembangan Kognitif Anak

Satu dari tiga anak di Indonesia mengalami stunting. Stunting dapat berdampak terhadap perkembangan motorik dan verbal, peningkatan penyakit degeneratif, kejadian kesakitan dan kematian. Selain itu, keadaan stunting akan mengakibatkan pertumbuhan dan perkembangan sel-sel neuron terhambat sehingga mempengaruhi perkembangan kognitif pada anak. Oleh karenanya, penelitian ini bertujuan untuk mengetahui dampak stunting terhadap kemampuan kognitif pada anak. Metode yang digunakan adalah literature review yang diambil dari jurnal nasional atau internasional maupun website. Penelusuran sumber pustaka dalam artikel ini melalui database Sinta, Google Scholar dan Pubmed dalam 10 tahun terakhir. Berdasarkan hasil telaah didapatkan hasil bahwa stunting memiliki implikasi biologis terhadap perkembangan otak dan neurologis yang diterjemahkan kedalam penurunan nilai kognitif. Anak dengan stunting mengalami 7% penurunan perkembangan kognitif dan nilai matematikanya lebih rendah 2,11 dibanding anak yang tidak stunting. Dalam Tes Kosakata Gambar Peabody dan tes Penilaian Kuantitatif, anak yang stunting mendapat skor 16,1% dan 48,8% lebih rendah dari anak yang tidak stunting. Anak yang mengalami stunting pada 2 tahun pertama kehidupan berpeluang memiliki IQ non verbal < 89 dan IQ lebih rendah 4,57 kali dibandingkan IQ anak yang tidak stunting. Dengan demikian dapat disimpulkan bahwa stunting memiliki pengaruh negatif terhadap kemampuan kognitif anak yang berdampak pada kurangnya prestasi belajar.

Keterlibatan Orangtua Dalam Perkembangan Literasi Anak Usia Dini

Penelitian ini bertujuan untuk mengungkap bentuk-bentuk keterlibatan orangtua dalam perekembangan literasi anak usia dini. Dalam penelitian ini keterlibatan orangtua dilihat dari penyediaan fasilitas, kualitas interaksi yang dilakukan dan kebiasaan orangtua/keluarga. Informan dari penelitian ini adalah ibu dari anak usia dini yang memiliki kemampuan literasi lebih rendah, sedang dan lebih tinggi dari anak seusianya. Metode pengambilan data dari penelitian ini adalah menggunakan wawancara langsung, observasi dan dokumentasi. Metode analisis data dalam penelitian ini menggunakan analisis data induktif deskriptif. Dalam penelitian ini data yang diperoleh merupakan data kualitatif yaitu data yang bersifat narasi deskriptif. Hasil penelitian menunjukkan bahwa praktek pembelajaran yang bersifat monoton, rutin, dan terjadwal dengan menggunakan cara/fasilitas yang sama kurang mengembangkan minat dan keterampilan literasi anak. Di sisi lain, penyediaan fasilitas yang bervariasi, menarik, serta dapat digunakan untuk bermain dapat merangsang minat serta keterampilan literasi anak. Selain itu, kesadaran orangtua dalam mengajarkan literasi sejak dini dan kepekaan orangtua dalam menangkap ketertarikan/ketidaktertarikan anak dalam proses pembalajaran merupakan hal yang penting sebagai bekal orangtua dalam mengajarkan literasi. Cara-cara yang bersahabat seperti bermain bersama, intonasi yang lembut dan sebagainya juga merupakan hal yang dapat menjaga mood anak dalam proses pembelajaran literasi

PAUD SEBAGAI PENANAMAN KARAKTER PEDULI LINGKUNGAN UNTUK MENCAPAI TARGET SUSTAINABLE DEVELOPMENT GOALS (SDGS) : SEBUAH STUDI LITERATUR

Abstract : Early childhood education is a coaching effort to shape children into good individuals through various educational stimuli. This is also inseparable from the importance of instilling good character. One of them is the character of love for the environment. which will have a sustainable impact considering children as a generation in life. Ensuring a healthy life by protecting the environment is one of the SDGs programs. Therefore the importance of awareness and concern for the surrounding environment that can benefit nature as a form of development. It is also based on natural phenomena such as natural disasters and environmental damage caused by various natural or non-natural and human factors. So that the urgency of the need for awareness to all elements of society must be carried out from the bottom and in a sustainable manner. Therefore, education is expected to be an approach to instilling the character of a love for the environment in children from an early age. This study uses a literature review approach to look at ideas about early childhood education in instilling environmental love characters in children to achieve the target of Sustainable Development Goals (SDGs). This study argues that the importance of inculcating a love for the environment in children through early childhood education can be an approach to achieving the target of Sustainable Development Goals (SDGs).

Challenges in Applying Higher Order Thinking Skills Assessment in the Teaching of Arabic in Indonesia

One of the teachers’ responsibilities in the teaching and learning process is to conduct assessments. The main purpose of assessment is to understand students’ learning outcomes. Based on the outcomes, teachers can give feedback to improve the planning and the implementation of the teaching process and to determine the quality of the assessment instrument. The Higher Order Thinking Skills (HOTS)-based assessment is urgently needed in schools to produce competitive graduates who have the critical thinking, communicative, collaborative, and creative skills. However, there are some challenges in the implementation of HOTS-based assessment, such as students’ low motivation and Arabic competence, ambiguous definitions of basic competencies in the curriculum, and lack of HOTS materials in textbooks. These challenges can be solved by making an acquisition-based learning of Arabic, reconstructing the descriptions of basic competence, and adapting HOTS-based assessment which is in line with the students’ ability. Keywords: challenges, HOTS, Arabic teaching, solution

Optimisation of phenolic compounds extraction from misai kucing using RSM

Misai kucing or the scientific name is Orthosiphon stamineus contains lots of phenolic compounds such as phenolic acid, flavanoids and antioxidants. These compounds have various benefits likes antifungal, antimicrobial, antitumor and antibacterial. Besides that, people also used it as remedy to treat the diseases. In order to get components from plant materials, normally they used extraction method. The yield of phenolic compounds extraction is dependent on the size of particles, solvent used, extraction method, power irradiation and condition. The method used for this work is microwave assisted extraction was studied by using response surface methodology (RSM) design for optimization. The 2 level factorial and Box behnken design have been used to determine the optimum extraction and to develop a quadratic polynomial. The highest peak for rosmarinic acid from the extraction of misai kucing is 2.203 at 2.00 to 2.30 minutes while the standard peak of rosmarinic acid is at 2.215 at 2.00 o 2.30 minutes. The highest yield of rosmarinic acid (RA) of 24.7971 mg RA/g DW was obtained at 66.6% of aqueous ethanol concentration with 112W microwave power for 3.75 minutes. The yield for total phenolic content (TPC) and total flavonoid content (TFC) are 48.51 mg GAE/g DW and 233.243 mg QE/gDW respectively. The optimum yields were obtained at 54.68% of ethanol at 170W of microwave power for 4.34 minutes. The lower total solid (TS) was produced higher rosmarinic acid per DW of material but higher TS contain more rosmarinic acid and hence it is affect by reduced its solubility in solvent and lower extraction yield. Longer extraction time increased rosmarinic acid extraction yield at lower TS (0.1 g/ml) because longer time needed for rosmarinic acid to diffuse in the solvent. Since solvent is not saturated at lower TS so the extraction process continues and become higher at longer time. The microwave assisted extraction provides rapid extraction of phenolic compounds without significantly compromising the extraction yield
