Long beans are seasonal vegetable crops that are widely used by people in Indonesia and are one type of vegetable that is sold daily. The use of long beans is very diverse, which is served for a variety of dishes from raw to cooked. The parts of long bean plants that can be consumed are the leaves and pods. The purpose of this study was to determine how much influence the application of mulch and manure had on the growth of long beans (Vigna Sinensis L.). The study was conducted in Jatenan Village, Kedungpring District, Lamongan Regency. The altitude of the place is ± 7 meters above sea level. The time of the study was carried out from February to March 2021, using the factorial Randomized Block Design (RAK) method, which consisted of 2 factors with 3 replications. The results of the study of the Effect of Cow Manure Application on the Growth and Production of Long Beans (Vigna Sinensis L.) The results of the study of the Effect of Mulch and Cow Manure on the Growth and Production of Long Bean Plants (Vigna Sinensis L.) can be seen that the best treatment is the goat manure treatment (P1) and plastic mulch treatment (M2) than the other treatments.

Abstract. The purpose of this study was to analyze the ability of chives leaves of ethyl acetate fraction to dissolve calcium in human kidney stones. This research starts from making the ethyl acetate fraction, calibration curve for calcium and measuring dissolved calcium levels in kidney stones by using atomic absorption spectrophotometry. The results showed that the ethyl acetate fraction with a concentration of 2.5% had the greatest anti-calculi capability of 92.02%. The conclusion of this study is that the ethyl acetate fraction of chives leaf has the potential to be anticalculi in the treatment of kidney stones.   Abstrak. Tujuan dari penelitian ini adalah untuk menganalisis kemampuan fraksi etil asetat daun kucai  untuk melarutkan kalsium pada batu ginjal manusia. Penelitian ini dimulai dari pembuatan fraksi etil asetat, pembuatan kurva kalibrasi kalsium serta pengukuran kadar kalsium terlarut pada batu ginjal dengan menggunakan spektrofotometri serapan atom. Hasil penelitian menunjukkan bahwa fraksi etil asetat dengan konsentrasi 2,5 % memiliki kemampuan antikalkuli yang terbesar yakni 92,02%. Kesimpulan penelitian ini adalah bahwa fraksi etil asetat daun kucai berpotensi sebagai antikalkuli pada pengobatan batu ginjal.
