Abstract

physiological or metabolic processes that can cause cancer in humans. Adsorption is one of the method that is quite effective for removing Cr(VI) in waters because this method uses low cost with good efficiency. Sugar palm fruit peel waste can be used as an adsorbent because it contains active compounds such as carbohydrates, proteins, fats that can play a role in the absorption of metal ions. This sugar palm peel waste will be immobilized using a Ca-alginate medium to increase the absorption of mechanical forces in the adsorption process. The sugar palm fruit peel was activated using 4% NaOH, which was then immobilized by Ca-alginate. The adsorbent was tested to determine its functional group using FTIR and using SEM EDX to see the surface morphology and the elements present in the adsorbent. The results showed that the optimum absorption of metal ions Cr(VI) using Ca-alginate immobilized palm peel as adsorbent at optimum pH 2 with an efficiency of 63% and adsorption capacity of 0.35396 mg/g, the optimum contact time was 75 minutes with an efficiency of 73, 83% and adsorption capacity of 0.41314 mg/g and the optimum concentration at 150 ppm with adsorption capacity of 13.15185 mg/g

Abstract

Setiap jenis tumbuhan ataupun tanaman memiliki bagian morfologi yaitu daun, batang, buah, bunga dan akar. Tidak banyak dari kita yang tahu bahwa beberapa jenis daun ternyata bisa dimanfaatkan sebagai bahan seni atau kerajinan yang bernilai tinggi. Misalnya daun sirsak, daun nangka, daun jeruk, daun rambutan, daun pterydophyta dan lain-lain. Banyak kita jumpai jenis-jenis tanaman tersebut dibudidayakan oleh masyarakat karena buah dari jenis tanaman tersebut memiliki nilai ekonomis yang tinggi. Akan tetapi banyak dari masyarakat tidak memanfaatkan daun dari jenis tanaman tersebut, padahal daun dari jenis tanaman tersebut bisa berpotensi sebagai obat-obatan, selain itu bisa juga digunakan untuk produk kerajinan tangan yaitu dibuat menjadi souvenir. Sekitar desa tangkit banyak terdapat berbagai jenis tanaman yang umumnya tumbuh liar yang tidak terlalu dimanfaatkan dan hanya menjadi sampah. Hal ini memiliki potensi untuk dikembangkan sebagai produk yang memiliki nilai ekonomi seperti souvenir. Produk dapat dihasilkan dengan memberdayakan ibu rumah tangga untuk dapat membantu perekonomian keluarga yang semakin sulit akibat semakin menipisnya stock bahan baku batu bata yang menjadi sumber utama perkenonomian warga. Kegiatan pembuatan souvenir ini sangat penting dilakukan karena bahan dan alatnya sangat mudah didapatkan serta prosedur kerjanya yang tidak susah sehingga ibu-ibu rumah tangga bisa membuat souvenir.

Abstract

As a resource, the local cultural value of Batik Jambi with the Sungai Penuh motif is one of the driving forces in the improvement of the economy, capacity, expertise, and reputation of the region. In reality, the development of Batik Jambi with the Sungai Penuh motif is still relatively stagnant. The demand and interest in Batik Jambi with the Sungai Penuh motif have not seen significant growth from year to year. It is can be attributed to several issues, one of which is the lack of knowledge and skills regarding innovation in batik making, resulting in no distinguishing features compared to other batik motifs from the archipelago. As a solution to this problem, training and mentoring should be provided to members of the Batik community in Sungai Penuh City to innovate the Batik products they produce. The innovation introduced in this program involves the use of photochromic dyes. The basis of photochromic dyeing is the phenomenon of reversible color change induced by light in photochromic molecules, causing the molecules to exist in two different forms. These two different forms of molecules result in different colors. Practically observed, photochromic dyeing causes the applied batik products to change color when exposed to sunlight (color-changing - sun activated).
