Abstract

Mikroplastik merupakan partikel plastik berukuran <5 mm yang telah menjadi polutan global di berbagai ekosistem akuatik termasuk perairan Lombok. Penelitian ini bertujuan untuk mengidentifikasi jenis polimer mikroplastik yang terdapat di perairan Lombok menggunakan teknologi Fourier Transform Infrared-ATR. Sepuluh sampel mikroplastik (MCP1-MCP10) dikumpulkan dari berbagai lokasi di perairan Lombok pada tahun 2025. Analisis FTIR dilakukan dengan resolusi 4 cm⁻¹ terhadap semua sampel untuk mengidentifikasi gugus fungsi karakteristik dari setiap polimer. Hasil penelitian menunjukkan bahwa perairan Lombok terkontaminasi oleh lima jenis polimer utama: Polyethylene (PE) 40%, Polyvinyl Chloride (PVC) 20%, Polypropylene (PP) 10%, Polystyrene (PS) 10%, dan Polyethylene Terephthalate/Polyamide (PET/PA) 20%. PE dan PVC merupakan polimer paling dominan, diindikasikan oleh puncak spektral khas pada bilangan gelombang 540-700 cm⁻¹ dan 2900 cm⁻¹. Potensi sumber kontaminan diduga berasal dari aktivitas pariwisata, perikanan, pemukiman pesisir, dan limbah domestik. Penelitian ini memberikan wawasan penting tentang komposisi polimer mikroplastik di perairan Lombok dan dasar untuk kebijakan pengelolaan limbah plastik yang lebih efektif di wilayah pesisir.

Abstract

The eruption of Mount Samalas is the largest volcanic eruption event in Indonesia that occurred in 1257 AD. The eruption column reached 43 km, and produced pyroclastic material that was widely distributed on Lombok Island. Pyroclastic material from the eruption of Mount Samalas is characterized by the presence of pumice. Mataram City is one of the areas affected by the eruption of Mount Samalas. This study aims to determine the presence and distribution of pumice produced by the eruption of Mount Samalas in Mataram City, especially Ampenan District and Sekarbela District. The methods used in this research are georadar method and resistivity geoelectric method. The results obtained show that pumice is distributed in all research locations and found at varying depths, namely the range of 0 - 9 meters. The pumice found is mixed with other materials such as sand, gravel, silt, tuff, and clay.

Abstract

Lombok has become one of the leading tourist destinations, especially with the development of the Mandalika Special Economic Zone. One of the cultural products that has the potential to be offered to tourists is Lombok traditional weaving. The study aims to analyze the effect of the pH of the dye solution on the characteristics of the dyed fabric. The research method uses a mechanical thermal method to obtain anthocyanin powder extraction, standard staining methods namely mordan, staining, and fixation, as well as characterization using tensilons, Color Analyzer software, Hooloovoo, and Encycolorpedi website. The extraction of anthocyanin compounds from teak leaves (Tectona grandis) was successfully carried out by mechanical thermal method. Color analysis and identified color changes are significantly affected by differences in solution pH. The higher the pH used, the darker the color will be produced and the higher the level of color fading in the fabric. The smallest  E value is at pH 6 =5.364 and the largest  E value is at pH 14 = 17.145. However, an increase in pH tends to increase the tensile strength of the fabric. However, the optimum tensile strength condition was obtained in a solution of pH 12, which was 17.414 MPa, while at pH 13 and pH 14, the tensile strength of the fabric decreased to 16.071 MPa. Based on the analysis of the influence of pH of dye solution on fabric tensile strength, it was identified that a 6th-order polynomial model (determination coefficient R2 = 0.9479) was identified as accurate enough to model the influence of pH on fabric tensile strength. Therefore, this finding has potential in the textile industry, especially in increasing the economic value of Lombok weaving.

Abstract

Pengabdian kepada Masyarakat (PkM) ini dilatarbelakangi oleh minimnya data kualitas udara, khususnya konsentrasi partikel halus (PM2.5), di kawasan pesisir Sekotong Barat yang berpotensi terpapar polusi dari aktivitas antropogenik dan alamiah, sehingga diperlukan sistem pemantauan yang representatif. Tujuan PkM ini adalah untuk melakukan pemasangan dan menyosialisasikan jaringan sistem pengukuran sebaran fine particle guna memetakan tingkat pencemaran udara berbasis partikulat secara real-time di wilayah tersebut. Metode pelaksanaan mencakup survei lokasi untuk menentukan titik pemasangan yang strategis, instalasi sensor partikulat yang terhubung ke sistem pencatatan data, serta pendampingan dan pelatihan kepada masyarakat mengenai operasional dan interpretasi data. Hasil implementasi menunjukkan bahwa jaringan sistem telah terpasang dan beroperasi dengan baik, menghasilkan data awal sebaran PM2.5 yang bervariasi berdasarkan waktu dan lokasi, sementara pembahasan mengindikasikan bahwa data ini dapat menjadi dasar ilmiah bagi pemangku kepentingan dalam upaya pengelolaan lingkungan dan peningkatan kesadaran masyarakat akan pentingnya kualitas udara.
