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

Onion skin contains the minerals Ca, K, Mg, P, Zn and Fe as well as the hormones auxin and gibberellin. The hormones auxin and gibberellin are hormones that trigger plant growth and stimulate the growth of shoots and roots. The content of acidic groups in liquid smoke is also able to encourage growth and strengthen plant roots. Research on the combination of these two materials Liquid Organic Fertilizer (POC) is still not much done. This research is expected to increase plant growth and prevent plant diseases. Liquid Organic Fertilizer formulation is applied to spinach plants because spinach can be harvested in a short time, namely 25 days. The purpose of this study was to determine the effect of variations in the formulation of Liquid Organic Fertilizer and the frequency of application of Liquid Organic Fertilizer on the height and number of leaves of spinach plants. The research began with maceration of shallot skin using 96% ethanol solvent, then making Liquid Organic Fertilizer formulations by mixing coconut shell liquid smoke and shallot skin extract at a volume ratio of 1:0, 0:1, 1:1, 3:7 and 7:3. Each Liquid Organic Fertilizer formula was applied to spinach plants with a frequency of 0, 7 and 15 days. The data obtained were then analyzed using ANOVA and continued with Duncan's test. The results showed that the Liquid Organic Fertilizer formula had a significant effect on the height of spinach plants but the Liquid Organic Fertilizer formula did not have a significant effect on the number of spinach plant leaves. The best liquid organic fertilizer formula is 3:7. The frequency of application of Liquid Organic Fertilizer formula did not have a statistically significant effect on the height or number of leaves of spinach plants.
