“…The brazilin compound is very easy to oxidize due to the addition of OH and turns into a brazilein compound, for this reason, the color produced by sappan wood can be different according to the pH of the solvent used. In this study, sappan wood was extracted using water that has a pH range of 6-7, so that the resulting color is red to purplish red [8,13]. So when applied to betung bamboo coloring, the bamboo will be brownish red on the inside, and very dark brown on the outside.…”

“…Based on this description, this research examines bamboo colored using synthetic dyes, natural dyes, and examines the effect of using preservatives. The natural dye used in this research comes from sappan wood which contains brazilein compounds that produce a red color when the pH is neutral [8]. While the synthetic dye used is Wantex dye no.…”

Bamboo is a widely utilized product. The use of dyes in coloring is now becoming important in bamboo dyeing as color can provide consumer appeal and improve aesthetics. Unlike wood, bamboo has a relatively uniform color, which is beige on the inside and green on the outside. Another important step in bamboo processing is preservation. This research examines bamboo colored using synthetic dyes using textile dyes which are azo group, natural dyes derived from the extraction of sappan wood, and examines the addition of borax boric preservatives. There are four treatments: natural dyes with preservatives, natural dyes only, synthetic dyes with preservative, and synthetic dyes only. Several tests were carried out, namely retention, penetration, staining evaluation using the CIELab method, and color change tests. It was found that natural dyes exhibited higher retention than synthetic ones, and both dyes without preservatives surpassed those with preservatives. Penetration was higher in natural dyes and those with preservatives. In comparison to the natural dyes, the color produced from synthetic dyes has a higher red intensity and a darker brightness level. While the addition of preservatives produces a lighter color with a higher brightness value. All treatments showed discoloration due to UV light exposure.

Untuk meningkatkan jumlah penjualan batik di Kampung Batik Kauman maka perlu diupayakan adanya variasi jenis produk dan efisiensi dalam pembuatannya. Salah satunya dengan membuat produk kain printing/cap bermotif batik dengan zat warna alam yang mudah dan cepat dalam pembuatannya sehingga biaya produksinya lebih murah. Produk kain cap ini lebih diminati dan memiliki daya saing di pasar domesti dan global karena produk yang dihasilkan bersifat ramah lingkungan. Selain itu dalam produksinya dapat mengurangi pencemaran, khususnya lingkungan perairan mengingat Kampung Batik Kauman berada ditengah-tengah pemukiman dan di jantung kota Surakarta. Untuk itu pada kegiatan PkM dilakukan pelatihan pembuatan kain cap yang diikuti 20 pengerajin batik dari Kampung Laweyan. Pelatihan dimulai dengan penjelasan oleh mahasiswa mengenai bahan, peralatan, resep, dan tahapan dalam pencapan kemudian dilanjutkan dengan praktek proses persiapan pada kain yang akan dicap, pembuatan pasta cap, dan proses pencapan pada kain. Diakhir pelatihan, peserta diberikan kuesioner untuk membuktikan keberterimaan ketrampilan pencapan yang telah diperoleh dalam pelatihan. Hasil pengisian kuesioner menunjukkan 100% peserta menyatakan pelatihan yang diikuti dapat meningkatkan pengetahuan dan ketrampilannya. 100% menyatakan hasil pelatihan dapat diterapkan untuk pengembangan usaha dan 89% peserta pelatihan dapat melakukan sendiri pembuatan kain cap. Hasil pencapan dinilai sebagian besar pengerajin kualitasnya belum memuaskan karena dari hasil penilaian peserta hanya 32% saja yang menyatakan kualitas hasil pencapannya baik dan 68% peserta yang menilai ketuaan warna hasil pencapan cukup tua. Untuk itu masih perlu dilatihkan kepada pengerajin cara peningkatan kualitas hasil pencapan agar pembuatan kain cap zat warna alam benar-benar dapat diterapkan dalam pengembangan usahanya.

Objective: Disclosing Agents derived from natural materials are still very minimal. The use of natural materials will increase economic value and have a high level of security. Disclosing solution is the material used to see the presence of plaque. The purpose of the study was to determine the stability of secang wood extract gel preparations based on the biological parameters of Escherichia coli and Salmonella typhi bacteria. Theoretical framework: Research on secang wood has been widely carried out in research on food and beverage ingredients, fabric coloring and fish tanning, beauty. This research was carried out to obtain natural coloring materials and made them in the form of a disclosing agent (disclosing solution), which is useful for checking the cleanliness of a person's teeth. Disclosing agent (disclosing solution) is a plaque coloring agent used in dentistry with the aim of being able to see the effectiveness of oral hygiene measures or to see the presence of a thin layer on the surface of the teeth (biofilm) known as dental plaque (Dyvta et.al., 2009). Method: The research is experimental, adult secang wood is taken and washed using sterile aqua pro injection which is flowed clean, drain, dry and make powder. The powder halved is extracted using different solvents namely ethanol and aquades. Continued making gel with an extract concentration of 10% (w/w). HPMC is dissolved into 50 mL of aquadest on a beaker with a temperature of 80-90 oC, stirred slowly to form a gel mass. Results and conclusion: The results showed that the gel base of the second and third months had contamination, while in the negative control there was contamination from the first to the third month. Statistical tests showed significant differences between the secang wood extract gel group and the positive control and gel bases. Of microbial contamination test results do not contain Escherichia coli contamination and Salmonella typhi bacteria in wood extract gel preparations for the zero month, first month, second month, and third month of storage, this shows that the gel preparation of secang wood extract is stable based on biological parameters. Implications of the research: The implication of this research is to produce a natural dye that can be used to detect plaque on the surface of teeth.
