Abstract

Zat aditif makanan hingga kini diketahui banyak macamnya dan beberapa diantaranya memiliki efek berbahaya bagi kesehatan manusia. Boraks dan formalin merupakan contoh zat aditif berbahaya yang peredarannya kini sudah dilarang. Namun, tidak menutup kemungkinan zat tersebut masih digunakan oleh sebagian masyarakat guna untuk mendapatkan keuntungan pribadi. Oleh karena itu, perlu adanya upaya agar masyarakat dapat mencegah paparan zat aditif berbahaya ini pada makanan. Deteksi adanya kandungan boraks dan formalin dapat dilakukan sendiri oleh masyarakat khususnya ibu-ibu rumah tangga dengan metode sederhana berbantuan bahan alami yang terdapat di lingkungan sekitar. Kegiatan ini berupa penyuluhan mengenai bahaya boraks dan formalin yang dimaksudkan untuk menghimbau masyarakat agar tidak mengonsumsi makanan yang mengandung zat tersebut. Kemudian dilakukan pelatihan pembuatan kit pendeteksi kandungan boraks dan formalin dengan bahan-bahan alami seperti kunyit dan getah papaya sehingga dapat dilakukan sendiri oleh masyarakat terutama ibu-ibu rumah tangga. Kegiatan pengabdian masyarakat oleh Tim Pengabdian Masyarakat Jurusan Teknik Kimia Universitas PGRI Madiun dilakukan dengan metode ceramah dan demonstrasi sehingga mampu meningkatkan pengetahuan ibu-ibu PKK di desa Bareng Kecamatan Babadan Kabupaten Ponorogo mengenai bahaya boraks dan formalin bagi kesehatan. Ibu-ibu PKK mengetahui cara deteksi adanya boraks dan formalin dalam makanan dengan menggunakan alat deteksi sederhana yang telah dibuat.

Abstract

Publikasi merupakan tahap akhir yang penting dilakukan dalam penulisan karya ilmiah. Publikasi adalah cara yang dilakukan agar karya atau hasil temuan dapat dikenal secara luas, sehingga dapat menambah dan mengembangkan ilmu pengetahuan. Guru dituntut tidak hanya mengajar tetapi juga menghasilkan karya atau temuan. Salah satu bentuk pengembangan profesi guru adalah pengembangan kemampuan guru dalam membuat karya tulis ilmiah. Kemampuan ini dapat dilihat dari publikasi para guru yang dimuat dalamberbagai media, khususnya jurnal ilmiah. Namun sebagian besar guru tidak mau menyusun dan melakukan publikasi karena membutuhkan waktu dan tenaga, sehingga guru hanya menyusun karya ilmiah tanpa melakukan publikasi. Program ini berupa sosialisasi mengenai publikasi karya ilmiah dimaksudkan untuk memberi pengetahuan dan memotivasi guru agar melakukan publikasi karya ilmiah ke dalam jurnal. Selain itu, dilakukan juga pelatihan publikasi karya ilmiah ke dalam jurnal sehingga dapat dilakukan sendiri oleh guru-guru khususnya guru SMK Al-Inabah. Hasil kegiatan ini yaitu pengetahuan guru tentang publikasi artikel makin meningkat.

Abstract

Corrosion is a chemical reaction between metal and chemical substances in free air influenced by typographical conditions, climate, and humidity levels around the metal object. If left unchecked, it can cause damage to the metal infrastructure, material losses, and harm in terms of safety and security. Therefore, a way to inhibit corrosion is needed by creating an environmentally friendly inhibitor from natural materials. One of them is by utilizing Sambiloti leaf as a natural inhibitor. Sambiloto leaves contain tannins which can inhibit corrosion well. This study aimed to determine the efficiency of Sambiloto leaves ethanol extract in inhibiting the corrosion rate of metals in the corrosive medium of well water. HCl was soaked for seven days to determine the correlation between the corrosion rate and extract concentration in different corrosive media. Sambiloto leaves were extracted using the soxhletation method using 96% ethanol solution, then distilled to obtain a pure extract. Sambiloto leaf extract was then varied in concentration, namely 1%, 5%, 10%, and 15%. The corrosive medium is well water and HCl, and the metal material used is nails. The results showed that adding Sambiloto extract with a concentration of 15% in both corrosive mediums had the highest inhibitor efficiency values, namely 97.32% in the corrosive HCl medium and 69.3% in the corrosive well water medium. The results of the regression analysis showed that the addition of Sambiloto extract had a significant effect on the corrosion rate in well water media. In contrast, in the HCl medium, the addition of Sambiloto extract did not significantly affect the corrosion rate.
