Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh variasi temperatur aktivasi (600oC, 700oC, 800oC, dan 900oC) terhadap daya serap logam timbal (Pb) dan seng (Zn) menggunakan arang aktif kayu mahoni. Arang aktif dihasilkan melalui proses preparasi, karbonasi dan aktivasi untuk menghasilkan butiran adsorben 100 mesh. Massa adsorben masing-masing 10 gr dan waktu kontak 100 menit. Adsorben dimasukkan ke dalam labu elemenyer yang terisi air logam kemudian dihomogenkan dan dilihat penurunan konsentrasi air logam tersebut. Konsentrasi air logam diukur menggunakan Atomic Absorption Spectrophotometer. Hasil penelitian menunjukkan kondisi optimum penyerapan logam Pb dan Zn pada temperatur 800oC dan 700oC. Efisiensi penyerapan logam Pb 82,84%, dan logam Zn 55,8%. Dapat disimpulkan bahwa semakin besar temperatur aktivasi dari suatu arang aktif, semakin tinggi daya serap dan efisiensi penyerapan logam Pb dan Zn.

Abstract

A prototype of (porous silicon (PS) based) NO(x=1.2) gas sensor based on porous silicon (PS) (operated at room temperature) has been fabricated. The sensor could be operated at room temperature. The (PS) basic material for the material sensor ( i.e. PS) was fabricated in the previous research by varying (parameter of the HF concentrations) concentrations of HF (what is HF?) and (the anodization time) time of anodizations. Its structure, as well as its optic, has been characterized. In this research, we did electrical characterization of PS to find its conductivity. The conductivity of PS is important because PS, as a sensor, utilizes the changes of conductivity when it is passed by NO(x=1.2). (The influence of these parameters on I-V characteristics of the PS and on the sensor performances has been studied in detail) The changes of electrical current because of the varying NO concentrations with time were measured using a current measuring system, then plotted. The result (shows) showed that the sensor could detect NO (and NO) gasses ranging from 16 ppb to 200 ppb and NO gas ranging from 12 ppb to 200 ppb, respectively at room temperature (28C) and at adjusted currents ranging from 20 to 800 μA. The result also showed that the sensor was not completely reversible for NO. xxx22ox

Abstract

This study aims to determine the use of iron sand extract and cashew nut shell activated charcoal in the capacitor manufacturing process and determine the effect of grain size on the capacitor capacitance with electrodes from a composite of iron sand extraction and activated charcoal from cashew nutshells. The sample preparation of cashew nutshell activated charcoal was carried out by carbonation and activation methods at a temperature of 700 0C and continued by extracting iron sand. The results of the iron sand extract were then crushed using a mortar, followed by varying the mass fraction of iron sand starting at 40%, 60%, and 80% for each particle size (60 mesh, 100 mesh, and 200 mesh). Then composite the iron sand extract and activated charcoal mixed for 4 hours, and added 0.7 mL of LiNO3 1M solution. The analysis showed that the highest specific capacitance was found in the 200 mesh grain size, namely 0.0695 F/g.

Abstract

Integrated community service activities KKN-Tematik are a forum for educating and training teachers and students using online learning as an effort to prevent Covid-19 with the purpose that teachers can carry out learning activities by online learning with utilizing several applications such as WhatsApp, Google Classroom, Google meet, and zoom. The activities on the work program KKN-Tematik begins with socialization to teachers in the location of each student, followed by educating and guided training on online learning methods and the use of several applications that can be used, as well as conducting trials involving several students. This activity received positive responses from the teacher with the seriousness and activeness of the teacher to find out the use of applications in online learning which so far has only limited to the use of WhatsApp through questionnaires. In addition, the ability and skills of teachers regarding the use of several applications have increased from the inability to use applications in online learning to be able to use these applications with the readiness of teachers to carry out online learning in the future. However, some of the barriers experienced by the teacher in the implementation of online learning are not yet maximal inability, so they still need further independent guidance and insufficient advice and infrastructure such as internet networks, data packets, and not all students have cellphones

Abstract

This study aims to determine the effect of KOH concentration on crystal structure, functional groups, and surface morphology of lauric acid extracted from coconut oil. The first stage is lauric acid extracted from coconut oil. The results of lauric acid were analyzed using three tools namely XRD (X-Ray Diffraction) which was useful to know the structure of lauric acid crystals, FTIR (Fourier Transform InfraRed) to determine the functional groups of lauric acid and SEM (Scanning Electron Microscopy) to determine the morphology of the surface of lauric acid. The results of XRD analysis at an angle of 2θ, the higher the KOH concentration, the clearer the diffraction peak at an angle of 2θ = 22 ° (002) which characterized lauric acid (C12) which had a monoclinic crystal structure and the results of the FTIR analysis, the higher the KOH concentration, showed the absorption at the number waves 1640.59 cm-1, 1637.03 cm-1, and 1647.89 cm-1 were not much different that have carbonyl functional groups (C = O) which were functional groups of lauric acid (C12).

Abstract

This research aims to determine the effect of activation temperature the crystal structure of activated charcoal. The material used activated charcoal bunches (Arengga Pinnate Merr). The process of making activated charcoal divided into two, namely the carbonization stage at a temperature of 250- 400 oC and the activation stage at a temperature variation of 600 - 800 ÌŠC. To find the crystal structure, the sample characterized by X-Ray Diffraction. The results of analysis the dominant elements diamond before activation with a percentage of 90.2% and an orthorhombic crystalline structure, where the lattice parameter a = 4.12700 Ã…; b = 4.93700 Ã…; c = 4.81900 Ã…. Peak Carbon has a hexagonal crystal structure in all temperature variations. Peak Graphite an orthorhombic crystal structure and at a temperature of 700 oC a hexagonal crystal structure formed. Therefore, giving temperature variations the activated charcoal of the bunches affects the structure of the formed Crystal. Wherein increasing the activation temperature, the crystal structure that forms look more amorphous marked by a widening diffraction peak intensity decreased crystals
