Efektivitas Metode Jarimatika Berbantu Kartu Bilangan Terhadap Hasil Belajar Materi Perkalian Siswa

Perkalian dasar merupakan kemampuan berhitung yang perlu dikuasai siswa kelas III untuk dapat menyelesaikan soal perkalian lanjutan atau perkalian susun. Namun, hal ini menjadi salah satu permasalahan berhitung karena siswa keliru dalam mengingat hasil perhitungannya, sehingga diperlukan metode berhitung untuk membantu menentukan hasil perkalian. Penelitian ini bertujuan untuk mengetahui efektivitas metode jarimatika berbantu kartu bilangan terhadap hasil belajar materi perkalian siswa kelas III SDN 15 Mataram Tahun Ajaran 2023/2024. Penelitian ini merupakan penelitian eksperimen jenis quasi eksperimental tipe nonequivalent control group design. Populasi dalam penelitian ini yaitu seluruh peserta didik kelas III SDN 15 Mataram. Teknik sampling yang digunakan yaitu sampling total dengan sampel sebanyak 21 peserta didik kelas III/A sebagai kelas eksperimen dan 23 peserta didik kelas III/B sebagai kelas kontrol. Teknik pengumpulan data dalam penelitian ini yaitu tes hasil belajar berupa tes pilihan ganda dan isian (pre-test dan post-test). Teknik analilsis data dilakukan terlebih dahulu dengan uji normalitas dan homogenitas terhadap data pre-test dan post-test sebagai prasyarat melakukan uji hipotesis dan N-gain. Pengujian hipotesis penelitian menggunakan perhitungan uji Independent Sample t-Test. Hasil perhitungan menunjukkan (4,82)>(2,02) pada signifikansi 5% dengan dk = 42 yang artinya  diterima dan  ditolak. Maka dapat disimpulkan bahwa ada perbedaan antara rata-rata nilai post-test kedua kelas yang artinya metode jarimatika berbantu kartu bilangan efektif ditinjau dari nilai post-test setelah pemberian perlakuan. Hal ini dapat dibuktikan dengan hasil uji N-gain yang didapat adalah 71,6% dengan kategori cukup efektif untuk pembelajaran yang menerapkan metode jarimatika berbantu kartu bilangan

Unraveling the Seismic Signal Anomaly at Mount Rinjani Station: In-Depth Exploration with the Detrended Fluctuation (DFA) Analysis Method in Connection with the 2018 Big Earthquake on Lombok Island, West Nusa Tenggara

We analyzed the seismic signals of the Mount Rinjani station to identify possible seismic anomalies before a series of major earthquakes on Lombok Island in 2018. We observe anomalies before earthquake events Mw >= 5.90. This research applies the detrended fluctuation analysis (DFA) method to investigate possible earthquake precursors associated with the analyzed earthquake. The results showed a relationship between scaling seismic signals (α) that exceeds the threshold of α values during the analysis period, and there is a deviation of the root mean square fluctuations in the corresponding scaling that should be rising but constant. The value of α with constant root mean square fluctuations occurs one to three days before the preliminary earthquake Mw 6.40 (28/07/2018) UTC and eight to 10 days before the main earthquake Mw 6.90 (05/08/2018). The Mw 6.90 earthquake had the most magnitude and could significantly contribute to the appearance of seismic anomalies.Rentetan gempa bumi di Pulau Lombok pada tahun 2018 terjadi pada bulan Juli hingga Agustus yang mengakibatkan banyak korban jiwa dan kerusakan berbagai infrastruktur. Gempa bumi awal terjadi pada tanggal 28 Juli 2018 (UTC) dengan magnitudo Mw 6,4. Kemudian gempa utama (mainshock) terjadi tujuh hari setelah gempa pendahuluan yakni 5 Agustus 2018 berkekuatan Mw 6,9. Gempa susulan terjadi pada 9 Agustus 2018 berkekuatan Mw 5,9 dan pada 19 Agustus 2018 berkekuatan Mw 6,9 dan Mw 6,3. Upaya untuk mengurangi dampak gempa bumi seperti yang terjadi di Pulau Lombok pada tahun 2018 adalah dengan mengetahui tanda-tanda awal sebelum gempa terjadi. Salah satu cara untuk memperkirakan waktu gempa adalah dengan mengidentifikasi anomali pada data sinyal seismik yang dapat dianggap sebagai prekursor. Pada penelitian ini data sinyal seismik yang bersumber dari stasiun Gunung Rinjani tahun 2018 diolah dengan metode Detrended Fluctuation Analysis. Berdasarkan hasil pengolahan data, gradien detrend sinyal seismik (α) teridentifikasi anomali satu hingga tiga hari sebelum kejadian gempa awal. Namun, masih diperlukan penelitian lebih lanjut untuk memastikan anomali tersebut dengan mengolah data beberapa tahun sebelum dan sesudah tahun 2018

Development of Student Cognitive Learning Outcomes Tests Based on Differentiated Learning

Differentiated learning is the core of the independent curriculum now. The aim of this research is to develop an instrument for measuring the cognitive learning outcomes of high school students based on differentiated learning on elasticity material and to obtain its characteristics. Differentiation, in this case, is differentiation of student learning styles. The instrument grid is arranged based on indicators of cognitive learning outcomes, which are then used to compile question items. The test instrument consists of two test sets, each of which has 9 items including two anchor items so that the total number of items is 16 items and has been validated by 6 experts. The validated instrument was tested on 252 respondents spread across high schools in the low, medium and high categories. Dichotomous data were analyzed using the Partial Credit Model (PCM). The trial results showed that all 16 items and the differentiated learning-based student cognitive learning outcomes test instrument were proven to be valid, fit the PCM model, and reliable, which means all items were in the good category. Thus, the test instrument developed meets the requirements for measuring the cognitive learning outcomes of high school students on elasticity material based on differentiated learning.Differentiated learning is the core of the independent curriculum now.

The Application of Different Fertilizers and Depths in The Rearing of Seaweed Caulerpa racemosa Using a Concrete Tank

This study used a concrete tank to analyze the interaction between different fertilizers and depths in C. racemose seaweed rearing. This study was experimental, using a factorial Completely Randomized Design (CRD) consisting of 2 factors, namely fertilizer (P) and depth (K). The fertilizers consisted of NPK (P1) and sap (P2), and the depths (K) consisted of 5 cm (K1), 10 cm (K2), and 15 cm (K3). Each treatment was repeated 3 times, so we had 18 combined treatments. The study was done at the Cultivation Laboratory of the National Innovation Research Agency (BRIN), Lombok, Indonesia. Research procedures included preparing material and tools, rearing C. racemosa, and harvesting C. racemosa. Research parameters included final weight, final length, specific decline rate, and survival rate. Data were analyzed using ANOVA. The results showed that the interaction of different fertilizers and depths affected the final weight, specific decline rate, and survival rate of C. racemosa. Meanwhile, the final length of C. racemosa was only influenced by different fertilizers. The best treatment happened in the interaction of NPK fertilizer and a depth of 15 cm, which gave a survival rate of 89%, a final weight of 88.66 g, and a specific decline rate of -10.67%/dayThis study used a concrete tank to analyze the interaction between different fertilizers and depths in C. racemose seaweed rearing.

According to the WHO data in 2019, nearly all of the global population resides in areas that do not meet the WHO guidelines for air quality. This study is to address the issue of indoor air pollution through the use of Photobioreactor technology and Hydrilla Verticillata plants. The experimental findings demonstrate that the rate of photosynthesis and production of oxygen bubbles by the Hydrilla plants are significantly influenced by adequate light intensity and exposure to CO2. By employing this innovative Photobioreactor technology, it is anticipated that indoor air quality can be enhanced, thereby contributing to the resolution of air pollution problems. This research adopts a combination of descriptive and experimental methods, utilizing a prototype scale for conducting experiments. Secondary data, in the form of published scientific articles from both international and national journals, serve as the source of data. The collected data is then qualitatively analyzed through descriptive means. Based on the results of data analysis, it can be concluded that this research offers valuable insights into the use of Hydrilla plants in innovative technologies for the improvement of air quality and human health, particularly by implementing photosynthesis processes within Photobioreactor technology
