Abstract

Rattan is one of the main materials in simple crafts and a material for interior furniture items. In Indonesia, rattan is very abundant and is one of the largest rattan producing countries in the world. On the other hand, this rattan material is very popular with furniture entrepreneurs because rattan can be made into creative products that have features both in terms of function and aesthetics.. Furniture produced includes chairs, tables, and decorative products. The application of rattan in making table lamps is found on the hood which uses rattan material with a four-axis rattan weaving technique. This technique Arrange the woven material in 4 different directions and will produce a woven pattern with more holes with hexagonal and octagonal pattern shapes. On the lamp body is made of wood glued to the sides of the wood. So the process of making this table lamp is through material observation and experimentation. The purpose of this design is to increase consumer attractiveness to interior needs. The application of rattan material in the design of table lamps produces products that are not only aesthetically pleasing, but also pay attention to aspects of sustainability and functionality needs.

Abstract

The process of implementing da'wah should have a good strategies, methods and management in order to produce quality of da'wah and achieve the predetermined goals of da'wah. Among the assemblies or institutions that oversee the field of da'wah are the Majelis Tabligh Pimpinan Wilayah Muhammadiyah, East Kalimantan. This research uses a type of field research, this is a research that collect data from interview, observation, and documentation. Based on the results of the research, planning the da'wah management of the Majelis Tabligh Pimpinan Wilayah Muhammadiyah of East Kalimantan includes determining the schedule, location, objectives, and activity budget. As for the organization of da'wah formed by structure and function as well as the division of tasks according to their respective fields. Furthermore, the mobilization of da'wah in management went well, the implementation of the da'wah program of the Majelis Tabligh, forming collaborations with various parties, providing guidance/motivation to the board of Majelis Tabligh and preachers. The practice of supervising da'wah in this case the chairman of the Majelis Tabligh provides formal oversight. This is the board of the Majelis Tabligh provides the results of the da'wah activities that have been carried out to the Pimpinan Wilayah Muhammadiyah. This institution has a responsibility to give an assessment, and provides non-formal oversight, by reprimanding members of the Majelis Tabligh who break the rules or are negligent in carrying out the trust.

Abstract

Inflammation serves as the body's defense mechanism in response to tissue damage caused by various factors. Echinacea contains flavonoids such as quercetin, kaempferol, and diosmetin, which exhibit significant anti-inflammatory properties by inhibiting inflammatory enzymes and reducing the production of proinflammatory mediators. This study aims to evaluate the anti-inflammatory effects of echinacea flower extract formulated as Lyotropic Liquid Crystal Nanoparticles (LLCN) and compare its efficacy with viscous echinacea flower extract and diclofenac sodium. Echinacea flower extract was produced using 70% ethanol solvent via ultrasonication. LLCNs were synthesized using a top-down approach and characterized based on particle size, zeta potential, stability, and absorption efficiency. Anti-inflammatory activity was assessed in vitro using 0.2% Bovine Serum Albumin (BSA) solution in Tris Buffer Saline (TBS), with diclofenac sodium as a positive control. The results showed that echinacea flower extract can be converted into LLCN with particle sizes ranging from 10 to 1000 nm. The LLCN formulation of echinacea flower extract showed stronger anti-inflammatory activity compared to the condensed extract, with activity recorded at 54,660 ppm, IC50 for LLCN at 21,823 ppm, and IC50 for diclofenac sodium at 19,984 ppm. Thus, echinacea flower extract LLCN has potential as a natural anti inflammatory agent, which shows higher efficacy compared to its condensed extract form. This indicates that LLCN technology not only improves the bioavailability, but also the effectiveness of the extract in inhibiting inflammation, thus LLCN has the potential to be applied more widely in the development of natural drugs for anti inflammatory therapy.

Abstract

The partners in the Community Service Programme activities are the mothers of RT 1 RW 8 Jumok Jaten. Partners are housewives who have been affected by the Covid 19 pandemic because most of them were laid off by the company. Partners have the opportunity to produce karak without borax. The problems faced by partners are: 1) Lack of knowledge of PKK mothers about the dangers of borax; 2) Limited knowledge and skills about making karak without borax; and 3) Limited knowledge and skills about food safety and packaging. The method that will be carried out to realise the objectives of the Community Service implementation programme is through: 1) Making karak without borax; 2) Financial management training; 3) Marketing management training. The results obtained by the partners were able to make karak without borax which has a compact texture, crispy, and savoury taste, making it safe for consumption.

Abstract

Perkembangan teknologi digital yang pesat telah membawa dampak signifikan terhadap pengelolaan dan penyimpanan data pribadi, khususnya data kependudukan seperti Nomor Induk Kependudukan (NIK), nama lengkap, alamat, serta tempat dan tanggal lahir. Data-data ini memiliki nilai strategis dan sangat rentan terhadap berbagai bentuk penyalahgunaan, mulai dari pencurian identitas, peretasan akun, hingga penipuan berbasis data pribadi sehingga membutuhkan sistem pengamanan informasi yang tidak hanya andal dan efisien, tetapi juga mampu menyamarkan data agar tidak mudah terdeteksi oleh pihak yang tidak berwenang. Penelitian ini bertujuan untuk memberikan metode pengamanan data kependudukan dengan menggunakan kombinasi kriptografi AES dan steganografi Chaotic LSB. Data kependudukan dienkripsi dengan AES disembunyikan secara acak menggunakan chaotic LSB kedalam media citra digital e-ktp yang hanya memuat foto dan nama. Hasil studi literatur dan simulasi konseptual menunjukkan bahwa kombinasi metode ini mampu menjaga kualitas citra digital dengan nilai Peak Signal-to-Noise Ratio (PSNR) lebih dari 30 dB, yang berarti tidak terjadi degradasi visual yang signifikan. Temuan ini mengindikasikan bahwa pendekatan tersebut dapat diimplementasikan secara efektif dalam sistem administrasi kependudukan berbasis digital untuk menjaga kerahasiaan dan integritas data. Dengan demikian, metode ini berpotensi menjadi solusi komprehensif dalam menghadapi tantangan keamanan data kependudukan di era digital.
