Abstract

Indonesia memiliki iklim tropis dimana jumlah radiasi ultraviolet (UV) yang mencapai permukaan bumi sangat tinggi. Paparan radiasi UV yang berlebih pada kulit dapat menyebabkan berbagai efek negatif seperti pencoklatan, eritema, kulit terbakar, dan kanker kulit. Salah satu upaya untuk mencegah efek negatif tersebut adalah menggunakan tabir surya dengan nilai SPF yang tinggi. Senna alata dan Anredera cordifolia merupakan tanaman yang berpotensi untuk dimanfaatkan sebagai bahan aktif tabir surya alami karena adanya kandungan senyawa polifenol serta nilai aktivitas antioksidan yang tinggi pada daunnya. Tujuan dari penelitian ini untuk menentukan nilai SPF kombinasi ekstrak etanol S. alata dan A. cordifolia (CSA) (1:1 v/v) dan kategori proteksinya. Penentuan nilai SPF dilakukan secara in vitro, menggunakan spektrofotometer UV-Vis pada panjang gelombang UV B (290-320 nm) selanjutnya nilai absorbansi yang didapat, dikalkulasi kedalam persamaan matematis Mansur. Penentuan kategori proteksi tabir surya berdasarkan nilai SPF mengacu pada ketentuan Food Drug Administrations (FDA). Hasil penelitian menunjukkan bahwa nilai SPF tertinggi CSA didapatkan pada konsentrasi 600:600 ppm yaitu 20.797 dengan kategori proteksi ultra sedangkan CSA pada konsentrasi 300:200 ppm menunjukkan nilai SPF terendah yaitu 5.228 dengan kategori proteksi sedang. Berdasarkan hasil tersebut, CSA memiliki potensi dikembangkan sebagai bahan aktif tabir surya dengan kategori proteksi sedang hingga ultra.

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. Mitra yang akan bekerjasama dengan kami adalah masyarakat khususnya ibu rumah tangga RT. 26 Desa Tangkit Kecamatan Sungai Gelam Kabupaten Muaro Jambi. Melalui kegiatan pengabdian ini diharapkan akan memberikan pengetahuan, keterampilan dan bakat berwirausaha kepada mitra yaitu masyarakat terutama Ibu-Ibu Rumah Tangga RT. 26 Desa Tangkit melalui pelatihan pengolahan limbah alam lokal menjadi produk bernilai ekonomi untuk membantu perekonomian keluarga. Dalam melakukan pengabdian pelatihan pembuatan souvenir dari limbah alam lokal, diharapkan dapat meningkatkan pengetahuan bahwa limbah alam lokal memiliki nilai ekonomis yang tinggi dan bisa dijadikan sebagai pendapatan. Kegitan ini juga diharapakan dapat meningkatkan softskill mitra dalam bidang kewirausahaan sehingga mitra dapat membuat atau mendirikan sendiri tempat penjualan dari souvenir gantungan kunci dari limbah alam lokal tersebut sehingga bisa membuka lapangan kerja bagi orang lain. Kegiatan dilaksanakan pada hari sabtu tanggal 23 September 2023 di Desa Tangkit Kecamatan Sungai Gelam, dimana ibu-ibu sangat antusias dalam mengikuti pelatihan, diakhir kegiatan terbuatnya produk souvenir gantungan kunci yang bisa membantu menambah penghasilan ibu-ibu dalam kehidupan sehari-hari.

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).

Abstract

Remazol Brilliant blue is an azo dye that is widely used in textile dyeing. The most appropriate handling method to be used in overcoming problems caused by textile dye waste is adsorption. Fly ash is an adsorbent that can be used to overcome this problem. Chemical activation was carried out using 1 M HCl solution. Besides that, physical activation was also carried out at 500°C for 1 hour. Research is needed to determine the optimum conditions for fly ash in dye adsorption to produce high adsorption efficiency. XRF characterization showed that palm shell fly ash was dominated by CaO of 71.064% and SiO2 of 15.734%. Characterization using FTIR shows the presence of Si-O groups in Fly ash. To analyze the surface morphology of the fly ash adsorbent, an SEM test was carried out and it was known that the surface morphology of the fly ash adsorbent after chemical and physical activation showed pore formation. Characterization using Surface Area Analyzer showed a surface area of 13.6153 m2/g. optimum absorption conditions at pH 6 with an adsorption capacity of 15.84 mg/g. optimum contact time of 60 minutes with an adsorption capacity of 15.54 mg/g. The optimum adsorbent mass is 0.5 g with an adsorption capacity of 9.54 mg/g and the optimum adsorbent concentration is at 200 ppm with an adsorption capacity of 69.08 mg/g. In this study the adsorption model used is the Freundlich isotherm. Based on the research result, it is known that fly ash is a suitable adsorbent for dye adsorption which is characterized by high color removal efficiency. Further characterization regarding the initial conditions of fly ash is needed as a comparison for fly ash after activation

Abstract

Corrosion is a decrease in the quality of a metal material caused by a reaction with the environment. Corrosion cannot be eliminated, but corrosion can be slowed down in several ways by adding corrosion inhibitors and synergistic effects. Acacia bark extract (Acacia mangium Willd) with the addition of 0.02 M KI has the potential as a corrosion inhibitor for steel because it contains secondary metabolites, so it can provide a synergistic effect and increase the value of inhibition efficiency on steel. This research aimed to analyze the effect of a mixture of acacia bark extracts (Acacia mangium Willd) with the addition of KI on inhibition efficiency corrosion of mild steel in sulfuric acid media. The method used in this study is the method of weight loss, adsorption isotherms, and thermodynamic parameters, which were carried out by varying the concentration of acacia bark extract and the immersion temperature of the steel. To strengthen the research results, characterization was carried out using FTIR and SEM. The results showed that the corrosion rate of mild steel immersed in 0.75 M H2SO4 corrosive medium with the addition of 0.02 M KI increased with increasing immersion temperature. These results are reinforced by the results of FTIR and SEM analysis which show that there is an interaction between mild steel and acacia bark extract (Acacia mangium Willd) and KI 0.02 M. Based on the thermodynamic parameters, the resulting values of ∆Hads, ∆Gads, and ∆Sads show that the adsorption process of acacia bark extract (Acacia mangium Willd) in corrosive medium H2SO4 0.75 M with the addition of 0.02 M KI took place spontaneously, showing the type of physical adsorption, adsorbed stable, the adsorption process was exothermic and the degree of irregularity in the adsorption process. The inhibition efficiency of acacia bark extract (Acacia mangium Willd) with the addition of 0.02 M KI was highest at 60 °C with an extract concentration of 2.5 g/L of 81%. The higher the immersion temperature, the greater the resulting synergistic effect

Abstract

The COVID-19 pandemic has increased online shopping and food delivery, causing a surge in single-use plastic waste and has become a habit to this day along with the rapid development of digital technology. Dream Central Waste Bank (BSI Dream) in Wijaya Pura Village collects 3 tons of waste monthly but lacked advanced plastic processing technology. This community service initiative aimed to implement a pyrolysis reactor to convert plastic waste into fuel oil and paving blocks, thereby enhancing economic value while promoting environmental sustainability. The activity stages included partner coordination and surveys, reactor performance upgrades, operational training, and evaluation. This activity involved five partners representing the Wijaya Pura Village community.  The reactor successfully produced fuel oil (density: 0.848–0.912 g/mL) and residues suitable for paving block production. The outcome of this initiative demonstrated improved skills among partners, the creation of marketable products and increased community income opportunities. Furthermore, the activity fostered greater awareness of the importance of sustainable waste management and supported the application of circular economy principles.

Abstract

Tilapia fish scales are among the fishery wastes that have not been optimally utilized, even though they have economic potential when processed into chitosan. Chitosan is a poly(2-amino-2-deoxy-β-D-glucose) obtained by deacetylation of chitin, with a high molecular weight ranging from 100 to 1.200 kDa, making it difficult to dissolve in water. To increase its solubility, chitosan can be depolymerized into oligochitosan with a lower molecular weight, around 5 – 10 kDa. This depolymerization process is influenced by temperature, time, and concentration factors. This study aims to determine the optimal conditions for the depolymerization of chitosan from tilapia fish scales using a central composite design (CCD). The stages of chitosan production include demineralization, deproteinization, and deacetylation, yielding a white powder with a molecular weight of 264.214 kDa and a degree of deacetylation of 74.24%. Based on CCD optimization, the optimal conditions for the depolymerization of tilapia fish scale chitosan were 3.6 M H2O2, 50 °C, and 2 hours, yielding a molecular weight of 3093 kDa. Fourier transform infrared (FTIR) characterization showed a peak shift from wave number 3267 cm-1 to 3303 cm-1. Oligochitosan also showed 100% solubility in water at neutral pH
