Green mussels (Perna viridis) are a type of processed water from a fairly high percentage of production. The high consumption rate is followed by the high amount of residual processing waste produced, namely in the form of shells. Unfortunately, mussel shell is a waste that is not used optimally. In the shells, there are a lot of mineral content, which when processed many benefits will be obtained. Clamshells have been studied to contain a fairly high source of the mineral calcium. This study is preliminary research focused on determining the ability of green mussel shell calcium powder to reduce iron levels in standard solutions with concentrations of 20, 40, 60, 80, and 100 mg / L. The results obtained from this study are the calcium content of green clamshells in the form of calcium carbonate (CaCO3) with calcium reaching 34.93% Wt and can be used properly to reduce iron metal levels.

Dragon fruit skin contains flavonoid compounds, one of which is anthocyanin. This anthocyanin can change color as the pH value changes so it can be applied as an acid-base titration indicator. The purpose of this research is to utilize red dragon fruit skin extract (Hylocereus polyrhizus) as an acid-base indicator in the titration process based on the influence of particle size (3.00 × 3.00 × 1.00) cm; (-14+18); (-18+20); (-20+70); (-70+100); (-100+120) mesh. The extract was obtained by maceration extraction for 24 hours with 96% ethanol solvent: 10% citric acid. The results of determining the color change trajectory were obtained when the acidic condition was light brown and when the alkaline condition was bright yellow. The highest result was obtained at particle size of -14 + 18 mesh with a rendement of 30.42%. The extract was tested as an acid-base titration indicator with a pH range of 8.3–10.0 for the pp indicator as a comparison, while methyl orange was used as a comparison with a pH of 3.1 – 4.4. So that this red dragon fruit peel extract can be used as an indicator in acid-base titration. Keywords: Acid-base titration, particle size, red dragon fruit peel

Saus merupakan jenis bumbu penyedap makanan berbentuk bubur, dengan warna merah atau oranye. Biasanya saus ditambahkan ke makanan sebagai penambah cita rasa, pada kasus tertentu terdapat pedagang yang tidak jujur dalam penggunaan produk saus. Seperti banyak kasus, untuk membuat saus terlihat lebih segar saus biasa ditambahkan pewarna makanan berwarna merah. Tidak jarang pewarna yang ditambahkan adalah pewarna tekstil berbahaya seperti rhodamin B. Jika dikonsumsi terlalu banyak dapat menyebabkan berbagai pernyakit seperti kerusakan hati dan ginjal, gangguan fisiologis tubuh, atau bahkan dapat menyebabkan timbulnya kanker hati. Untuk menghindari hal tersebut, muncul inovasi baru yaitu dektektor rhodamin B dari ekstrak daun tanaman kelor. Pada pembuatan inovasi dilakukan beberapa uji yaitu pengaruh detektor terhadap saus, penentuan kadar vitamin C, dan uji terhadap sampel. Hasil dari empat uji tersebut menunjukkan konsentrasi vitamin c tidak terlalu mempengaruhi perubahan warna. Konsentrasi yang dipakai adalah konsentrasi 2% dengan perubahan warna menjadi merah kirmizi jika positif. Diketahui hanya ada satu sampel saus yang dipakai oleh pedagang mengandung rhodamin B. Dari penelitian inovasi yang dilakukan dapat ditarik kesimpulan daun kelor dapat dijadikan alternatif uji kualitatif penentuan rhodamin B pada saus yang berdedar di Kecamatan Samarinda Sebrang, Samarinda. Kata kunci: Rhodamin b, Kelor (Moringa oleifera), Vitamin C, Kit
