Abstract

Perkembangan industri di suatu negara yang semakin pesat dapat menyebabkan dampak buruk bagi lingkungan berupa pencemaran logam berat yang berasal dari limbah hasil industri yang tidak diolah secara sempurna. Salah satu jenis logam berat yang keberadaannya tidak dibutuhkan makhluk hidup dan mempunyai sifat toksisitas tinggi adalah logam timbal (Pb). Dampak peningkatan konsumsi Pb dapat menyebabkan keracunan dan gangguan pada saluran pencernaan. Membran PVDF (Polyvinylidene Fluoride) dibuat dengan penambahan Al2O3 untuk mengetahui pengaruh penambahan Al2O3 terhadap karakteristik dan kinerja membran dalam pengurangan ion logam Pb2+. Membran PVDF dan PVDF - Al2O3 dikarakterisasi dengan kuat tarik, sudut kontak, dan uji fluks rejeksi. Membran PVDF 20% memiliki kuat tarik terbaik dengan nilai 7,55 MPa dan penambahan Al2O3 meningkatkan nilai kuat tarik menjadi 7,85 MPa. Penambahan Al2O3 pada membran PVDF dapat meningkatkan sifat hidrofilitas membran dengan menurunkan nilai sudut kontak dari 106,0° menjadi 83,6°. Membran PVDF - Al2O3 mampu meningkatkan nilai fluks hingga 38,997 L/m2.jam dan meningkatkan koefisien rejeksi hingga 97,44%. Nilai kadar ion logam Pb2+ berhasil diturunkan dari kadar 10 mg/L menjadi 0,225 mg/L.

Abstract

KKN students of Universitas Islam Negeri Walisongo Semarang held a cherry leaf tea-making activity with PKK women in Krandon village. Using cherry leaves to make tea bags is a creative idea from the students that can be applied in the health sector and as an entrepreneurial idea independently carried out by the community. This initiative is motivated by the fact that most of the population has high blood sugar, cholesterol, and uric acid levels. The primary purpose of this training is to socialize the health benefits of cherry leaves and provide entrepreneurial ideas for selling herbal tea bags from cherry leaves that can be made more attractive and have high selling value. The results of the cherry leaf tea-making training activities have positively impacted the people of Krandon village. Firstly, it can provide information about the benefits of cherry leaves that were previously unknown to the public. Previously, people only used the fruit without knowing that cherry leaves can also be used for health and as an entrepreneurial idea. Secondly, it motivates women to develop the use of cherry leaves as a selling idea. Thirdly, it can produce tea bags from leaves found in many places and substitute other herbal teas.
