Abstract

Melanjutkan studi ke perguruan tinggi merupakan impian banyak tamatan SMA sederajat. Untuk mewujudkannya, calon mahasiswa harus mempersiapkan diri dengan belajar dan bekerja keras, terutama bagi mereka yang tidak lolos jalur SNBP (Seleksi Nasional Berdasarkan Prestasi) dan harus menghadapi tes UTBK (Ujian Tulis Berbasis Komputer). Program pengabdian ini bertujuan memberikan pengalaman kepada siswa kelas XII tentang bentuk dan tingkat kesulitan tes masuk Perguruan Tinggi Negeri (PTN) serta cara penyelesaiannya. Pengalaman ini membantu siswa mengukur kesiapan mereka dalam menghadapi UTBK sekaligus memotivasi mereka meningkatkan waktu, kualitas, dan kuantitas belajar. Pelaksanaan program terdiri atas tiga tahapan: persiapan, pelaksanaan, dan evaluasi. Kegiatan utama meliputi: (1) review konsep matematika dasar, (2) ujicoba tes pengetahuan kuantitatif dan penalaran matematika, serta (3) pembimbingan soal ujicoba oleh tim. Hasil ujicoba menunjukkan kemampuan siswa dalam pengetahuan kuantitatif dan penalaran matematik masih rendah. Namun, pembimbingan terstruktur meningkatkan pemahaman siswa, menyadarkan mereka akan banyaknya materi yang perlu dipelajari, dan mendorong semangat belajar. Program ini juga membantu siswa lebih memahami jurusan yang diminati. Direkomendasikan kepada pihak sekolah untuk memberikan pembinaan intensif kepada seluruh siswa guna meningkatkan peluang lulus seleksi masuk PTN.

Abstract

Magnetite (Fe3O4) is a spinel-based material that has broad potential in various applications, one of which is for magneto-optics. However, the value of the energy gap obtained from magnetite is too small to be applied. Efforts to improve these characteristics are carried out through transition metal ion doping techniques, one of which is cobalt (Co2+) which is known to modify the electronic structure and stabilize the crystal lattice. This study aims to analyze the optical properties of magnetite nanoparticles that have been doped with Co2+ through energy gap and Urbach energy calculations. The synthesis of Co0.125Fe2.875O4 was carried out using the coprecipitation method. Furthermore, characterization was carried out using UV–Vis spectroscopy and analyzed the size of the energy gap and Urbach energy. The results showed that cobalt doping (Co0.125Fe2.875O4) produced two indirect energy gap values ​​of 2.07 eV and 3.19 eV and one direct energy gap value of 3.63 eV. Urbach energy analysis revealed a very low Eu value of 0.0073 eV, indicating high crystal regularity and minimal structural defects in the material. This study demonstrated that cobalt doping not only increases the band gap energy of magnetite but also significantly lowers the Urbach energy, resulting in a material with more pronounced optical properties.

Abstract

The Mandalika Central Lombok Special Economic Zone (SEZ) is one of the world-class national priority tourist destinations. However, until now there has been no branding of the village's superior woven products that can contribute significantly to the Mandalika SEZ. So it is important to carry out this service activity, to give birth to entrepreneurial pioneer weaving craftsmen towards "LOMBOK WEANING, LOCAL GOING GLOBAL". To achieve this goal, the craftsmen group experienced several problems (1) limited insight into the importance of developing weaving for the tourism sector towards international tourism and (2) the dyeing process was still using conventional methods which took a long time and was impractical. This problem arose due to a lack of human resources owned by the village, even though the natural resource potential it has really supports the songket weaving industrial center. Therefore, the role of academics is really needed to innovate to provide solutions to problems based on green technology. The solutions to the problems that will be offered are (1) activities to open people's insight into the importance of the tourism sector (2) dissemination of green synthesis technology using a modified steam extraction method to produce natural dye powder accompanied by students of the material characterization method course (3 credits). So that both solutions can be delivered appropriately, a systematic flow of activities needs to be carried out consisting of (a) socialization, training, (c) mentoring, and (d) monitoring and evaluation. A series of activities have been carried out, it is hoped that the craftsmen's skills will increase so that they are able to independently produce coloring powder from various existing local natural resources and be able to compete internationally. In addition, different types of leaves will produce different color pigments. Differences in dyeing processes and techniques will produce cotton threads with different qualities. In general, natural dyes always produce soft colors.

Abstract

Batik is an Indonesian cultural heritage that embodies deep philosophical values and national identity. However, traditional batik-making techniques are often considered complex for beginners since they require specific skills. Therefore, the tie-dye technique, also known as batik ikat celup, is introduced as a simpler and more accessible alternative that can serve both as a learning medium and as an entrepreneurial opportunity. This community service program was conducted at Pondok Pesantren Al-Intishor, Mataram, involving 9th and 10th grade students. The method included delivering introductory materials, demonstrations, and hands-on practice in small groups under intensive guidance. The results revealed high enthusiasm among both students and teachers, who acknowledged the relevance of this activity to be integrated into craft and entrepreneurship education. Students successfully understood the stages of tie-dye batik making—from material preparation to the drying process—while also developing creativity through unique motifs and color variations. This program proved effective not only in enhancing knowledge about batik but also in fostering practical skills, self-confidence, and basic entrepreneurial potential. Thus, tie-dye batik training can be regarded as a strategic medium to preserve cultural heritage while simultaneously improving participants’ economic independence.

Abstract

Doping is an effective approach to altering the electronic and structural properties of a material, thereby influencing its optical and magnetic characteristics. This study successfully synthesized and characterized cobalt-doped magnetite (Fe2.5Co0.5O4) nanoparticles from natural iron sand using the coprecipitation method. The main objective was to evaluate the optical properties of the synthesized material through UV-Vis spectral analysis and to compare the band gap energy values using three approaches: the Tauc method (direct and indirect transitions), the Kubelka–Munk method, and the Urbach energy calculation as an indicator of structural disorder. The characterization results revealed that the incorporation of Co2+ ions into the magnetite structure induced significant changes in the absorption patterns, including the emergence of new absorption peaks and a redshift in wavelength. The obtained band gap values were 3.71 eV (Tauc-direct), 2.18 eV (Tauc-indirect), and 2.33 eV (Kubelka–Munk), confirming the presence of two types of optical transitions. Furthermore, the relatively low Urbach energy (0.07138 eV) indicated that the crystal structure remained well-preserved despite the modifications induced by doping. This study highlights the importance of employing multi-method approaches for reliable optical characterization and demonstrates that Fe2.5Co0.5O4 materials derived from local resources possess promising potential for photocatalytic and optoelectronic applications.

Abstract

Fe3-xCoxO4 nanoparticles (x = 0.25 and 0.375) were successfully synthesized using natural iron sand as the base material through a coprecipitation method with the addition of CoCl2·6H2O as a cobalt source. Optical characterization was carried out using UV–Vis spectroscopy in the wavelength range of 200–800 nm to analyze the electronic properties of the material. The measurement results showed that increasing the cobalt fraction strengthened the absorption in the visible region and shifted the absorption onset to lower energies, indicating a narrowing of the band gap energy. Tauc analysis revealed that the direct gap energy decreased from 2.271 eV (x = 0.25) to 2.221 eV (x = 0.375), while the indirect gap energy decreased from 2.222 eV to 2.204 eV. Furthermore, the Urbach energy calculation shows an increase from 0.073 eV at x = 0.25 to 0.074 eV at x = 0.375, indicating an increase in local disorder that broadens the band tail. This finding is consistent with previous research reports on Co-doped magnetite and CoFe2O4, and confirms that cobalt doping is effective in enhancing the visible light absorption capacity. Thus, Fe3-xCoxO4 based on natural iron sand, especially at x = 0.375, has potential applications as an active material in visible light-based photocatalysis and solar energy optoelectronic devices.
