Sugarcane bagasse and eggshell waste are common types of waste found in Indonesia. This article introduces an innovation to utilize these two waste materials as bone implant materials, offering a way to increase their economic value. Bone implant materials primarily consist of SiO2 and CaO, both of which can be derived from sugarcane bagasse and eggshell waste. The process of making bone implants begins with the purification of sugarcane bagasse and eggshell waste to produce SiO2 and CaO compounds. Characterizations conducted at each stage of the reaction process in this research include FTIR, XRD, and SEM.The purification of sugarcane bagasse into SiO2 is carried out using a hydrothermal reaction, while the purification of eggshell waste is performed using the calcination method. Once the high-purity raw materials are obtained, the process continues with the production of bioactive glass. Bioactive glass is a biomatrix material used as a bone implant material. Its composition requires SiO2 = 45%, Na2O = 25%, CaO = 25%, and P2O5 = 5% (weight/weight). The sol-gel method is employed to produce the bioactive glass.After the bioactive glass material is produced, it is further characterized to evaluate its structure and properties. Additionally, bioactivity testing is conducted using SBF (Simulated Body Fluid) to ensure its safety when used as a bone implant and its interaction with body tissues.

Penyalahgunaan smartphone dan penurunan minat belajar peserta didik menjadi permasalahan yang serius pasca Covid 19. Hal ini terjadi karena pesatnya perkembangan teknologi tidak diimbangi dengan kontrol guru dan orang tua saat proses pembelajaran. Akibatnya, peserta didik menggunakan smartphone untuk kegiatan yang kurang bermanfaat. Permasalahan ini membutuhkan kreativitas guru agar kegiatan pembelajaran dapat menarik minat peserta didik. Oleh karena itu, dilakukan penelitian pengembangan media pembelajaran berbasis Android dengan model Problem Based Learning (PBL) menggunakan Powerpoint terintegrasi iSpring Suite. Metode penelitian yang digunakan adalah metode research & development (R&D) dengan model 4D. Subjek penelitian ini yaitu dosen sebagai validator ahli, guru sebagai validator praktisi, dan peserta didik sebagai responden. Kelayakan media ini dinilai oleh seorang dosen, dua orang guru, dan 37 peserta didik kelas XI IPA 1 dan XI IPA 2 SMA Negeri 1 Sukorejo. Penilaian dosen menunjukkan hasil layak pada ketiga aspek, respon guru menunjukkan hasil sangat layak pada dua aspek dan layak pada satu aspek, respon peserta didik menunjukkan hasil sangat layak untuk tiga aspek. Sehingga dapat disimpulkan bahwa media pembelajaran yang dikembangkan layak digunakan sebagai upaya mengatasi permasalahan rendahnya minat belajar peserta didik terhadap kegiatan pembelajaran yang disebabkan oleh perkembangan teknologi.

After the covid 19 pandemic, it had an impact on learning loss in the world of education. so that the Minister of Education, Culture, Research and Technology issued a decree to implement the independent curriculum as stated in the Decree of the Minister of Education, Culture, Research and Technology of the Republic of Indonesia number 262 / M / 2022. Based on the implementation of the independent curriculum that has been running from 2022, there has not been much discussion about the suitability of the Final Semester Summative Assessment in terms of learning outcomes and the distribution of cognitive domains. The research to be carried out uses a type of qualitative research with a descriptive approach. The research will be carried out by determining the object of research on purpose, so the technique used is Purposive Sampling. The suitability of ASAS for Learning Outcomes (CP) which has high results with an average of 78% with various aspects of assessment including completeness of material, breadth of material, depth of material, accuracy of facts and concepts, accuracy of case examples, and suitability for scientific and contextual developments. Based on the distribution of cognitive domains when viewed from the percentage of each school, S01 has an even distribution and shows all levels of Low Order Thinking Skills (LOTS), Middle Thinking Skills (MOTS) and High Order Thinking Skills (HOTS) but dominant in MOTS. The percentage in S02 shows ASAS instruments that have HOTS levels. While in S03, it represents the level of LOTS dominant test items. the knowledge dimension that is often presented is the conceptual dimension, which shows that the question seeks to improve students' concept understanding. 1) It is necessary to measure the ASAS instrument with several peers, so that the effectiveness of the measuring instrument and correlation can be determined 2) Analysis needs to be carried out by identifying the ASAS test instrument based on the AKM test instrum ent 3) The results of the study can be developed by preparing the ASAS test instrument based on the AKM test instrument.

Every year, the paint industry in Indonesia continues to grow. This is due to the growth of the property and housing sectors, which increases the demand for paint nationwide. This research aims to develop environmentally friendly wall paint using betacyanin pigment from red beet tubers through a maceration process as an alternative paint color that is sustainable and beneficial for health and the environment. Betacyanin pigment extraction was carried out using the maceration method with 96% ethanol for 48 hours, then filtered using filter paper and evaporated. Binder and pigment are mixed in a ratio of 14.3:2, 14.3:5, 14.3:8, 14.3:11, 14.3:14, and 14.3:17 until homogeneous. Paint characterization is done through pH, color, density, and adhesion tests. The research results show that the sixth paint variation, with a binder and pigment composition ratio of 14.3 ml:17 ml, provides the most optimal results that closely align with SNI. The paint has a deep red color, pH 7.6, density of 1.18 g/cm³, and adhesion of 100%.

Eyeliner is a decorative cosmetic or make-up product. Eyeliner functions to help emphasize and make the shape of the eyes more prominent and more expressive, make makeup more dramatic without doing many steps, and cover the false eyelash line that sticks to the eyes. This study aims to determine whether activated carbon from coconut shell waste can be used as a natural dye in eyeliner fabrication. This research uses a laboratory experiment method, namely by mixing materials consisting of distilled water, xanthan gum, tween 80, propylene glycol, methylparaben, CH_3 COOH solution with distilled water, ethanol, and carbon pigments in it. Xanthan gum and carbon are mixed in a ratio of 1:10; 1:12; 1:14; 1:16; 1:8; and 1:20 until homogeneous. Fabrication properties were tested, namely homogeneity, pH, drying time, and color tests on eyeliner fabrication. the results were analyzed descriptively. Based on the results obtained, the six fabricated formulations have a deep black color and have an average particle size of 8.1 µm, have an average pH of 6.3, an average drying time of 303 seconds, the six formulations have an evil Minister color, After Dark, Deep Forest chocolate, Holy Crow, Smoked black coffee, Indigo brown ink. It was concluded that pigments from coconut shell carbon can be used as natural dyes in eyeliner fabrication. However, in the physical properties test, namely the homogeneity test and dry time test for eyeliner fabrication, there are still discrepancies in the literature.
