Abstract

Sintesis karbon aktif yang berasal dari limbah kulit lada sebagai material pengolahan air pasca tambang timah (kulong) di Propinsi Kepulauan Bangka Belitung telah dilakukan. Karbon aktif dipreparasi secara kimia menggunakan aktivator KOH 3M dengan nisbah 1:4 dan dikuti dengan aktivasi secara fisika dengan aliran gas N2 pada suhu 600 0C selama 3 jam. Sampel karbon aktif hasil preparasi dan telah mengalami pencucian hingga pH netral selanjutnya dikarakterisasi menggunakan SEM-EDX untuk mengetahui struktur morfologinya. Kemudian sampel karbon aktif dilakukan pengujian pada air kulong dengan parameter tingkat kekeruhan dan Atomic Absorbsion Spectrophotometry (AAS). Hasil SEM-EDX menunjukkan bahwa morfologi sampel berpori, selain itu hasil uji tingkat kekeruhan dengan perlakukan penambahan karbon aktif mengalami penurunan. Hasil serupa juga terjadi pada pengujian menggunakan uji AAS. Berdasarkan hasil pengujian dapat disimpulkan bahwa karbon aktif limbah kulit lada dapat dijadikan sebagai material penyerap pada proses pengolahan air pasca tambang timah (kulong).

Abstract

Analisis sebaran lava bantal Watuadeg di Kecamatan Berbah DI Yogyakarta yang didukung data Vertical Electrical Sounding (VES )telah dilakukan.Keterdapatan lava bantal yang tersingkap di permukaan merupakan penanda bahwa dahulu daerah tersebut merupakan laut. Akibat proses geologi terutama tektonik mengakibatkan lava bantal tersebut terangkat kedaratan. Lava bantal yang belum tersingkap karena tertutup oleh soil (lapukan batuan) menjadi daya tarik tersendiri untuk dikaji. Persebaran lava bantal permukaan dominan mengalir dari sumbernya ke arah selatan dan menyebar ke tenggara serta dibatasi oleh Sungai Opak. Berdasarkan hasil analisis data VES, keberadan lava bantal di lokasi titik pengukuran berada di kedalaman 4 m dengan nilai resistivitas sebesar 1321,08 Ωm. Berdasarkan  dari data geologi dan nilai resistivitas batuan tersebut dapat disimpulkan bahwa penyebaran lava bantal  dominan ke arah selatan dari pusat erupsinya dengan sayap sebaran ke arah tenggara dan barat daya serta sebarannya masih ada di bawah permukaan

This study aims to determine the significant effect of WhatsApp based on Google Classroom and Google Meet with the implementation of the inquiry learning model in physics learning on student learning outcomes. The research was conducted during the Covid-19 pandemic with a DARING learning process, the method used was the pre-experimental method with one group pretest-posttest design. This research was conducted at SMA Negeri 1 Suwawa in the academic year 2020/2021 using saturated sampling technique and random selection of classes, obtained by students of class XI IPA 1 as an experimental class, class XI IPA 3 as replication class 1, XI IPA 4 as class replication 2 and class XI IPA 2 as replication class 3. The research instrument is in the form of an essay test of 8 numbers on the Dynamics of Rotation and Sturdy Object Balance with a KKM of 73. Based on the results of hypothesis testing, it is known that the t value for each experimental class is replication class 1, replication class 2, and replication class 3 are 4.16, 3.089. , 3.19, 3.386 greater than t table 1.705, 1.739, 1.71, 1.72, it can be concluded that there is a significant positive effect of treatment. Based on the analysis of the N-Gain and the effect size, the N-Gain value for the four classes, respectively, is 0.61, 0.59.0.59, and 0.62 in the medium category, for the effect size value is 1.9 with strong effect interpretation. This shows that there is consistency in the treatment given to student learning outcomes.

Abstract

Carbon Dots (CDs) which have been synthesized using the laser ablation method show the presence of UV-Vis absorption in the wavelength range of 303 nm to 333 nm for absorbance and 495 nm to 503 nm for fluorescence. Changes in the time duration 1, 2, 3 hours of CDs resulted in changes in the optical energy gap. The optical energy gap valuesare distinguished by the type of indirect transition (n=2) is 3.40 eV (1 hour), 3.15 eV (2 hour), 2.85 eV (3 hour) and direct transition (n=1/2) is 2.58 eV (1 hour), 2.31 eV (2 hour), 1.70 eV (1 hour).

Abstract

The sago fiber waste is promising as an active carbon material which has a high adsorption in purifying water process. The objective of this research was to make activated carbon from sago fiber waste to be applied for water purification and iron (Fe) adsorption with various of contact time. The carbon activation process uses Phosphoric Acid (H3PO4) and calcined at 800 °C for 2 hours. After drying, then analyzed the water content and ash content. Furthermore, surface morphology testing was carried out using SEM. The application of activated carbon was carried out in dig well water purification and filtering iron (Fe) based on variations in contact time of 10 minutes, 20 minutes, 30 minutes and 40 minutes. Analysis of water content of activated carbon was carried out 3 times with an average value of 3.9662%. Ash content analysis aims to determine the metal oxide content in activated carbon. Analysis of the ash content of activated carbon was carried out 3 times with an average value of 5.3239%. The average value of ash content meets the quality standards of activated carbon SNI 06-3730-1995 where the standard value of ash content for powdered activated carbon is a maximum of 10%. SEM test results show that the surface of the activated carbon is porous but the size is not uniform. The level of Ferrium (Fe) in water that has gone through the purification process using activated carbon. The most effective contact time was obtained, namely 20 minutes and had met the threshold requirements for water turbidity levels according to Minister of Indonesia health. This means that activated carbon from sago fiber is able to adsorb the material contained in water and also very capable in  picking up some bad contents of cloudy and polluted water.
