“…The Several studies also say that coconut water is able to preserve food ingredients from meat. Widaningrum et al (2015) stated that banana peel vinegar and coconut water were able to preserve chicken meat the same as commercial acetic acid when stored for 12 days.

Tomatoes are the popular fruit but having short shelf life. This fruit require some treatment to maintain it’s quality during post-harvesting. Eco-enzyme is a fermented liquid, it’s made by fermentation process of fresh waste vegetables or fruits. Previous study showed that spraying tomatoes with Eco-enzyme can maintain the shelf life of tomatoes. This study aim to observe the effect of various liquid in Eco-enzyme fermentation and it’s effect to tomatoes preservation by soaking method. The research was experiment research using quality scale of tomatoes. The Eco-enzyme was fermented using different liquid such as water, coconut water and rice rinsed water. Tomatoes were soaked with each Eco-enzyme treatment with 50% and 100% concentration of each liquid for 5 minutes then rinsed them and observed their quality for 8 days during storage process. The control treatments are non-soaked and non-rinsed tomatoes. The observation include the quality of tomatoes and the quality of Eco-enzyme. The result of this study found that modification of liquid in Eco-enzyme fermentation have different effect for tomatoes preservation. Soaking and rinsing method also have different effect for tomatoes. The best treatment for EE1 is EE1-rinse-concentration 50%, EE2 is EE2-rinse-concentration 100%, and EE3 is EE3-rinse-concentration 50%. The soaking followed rinsing was the best method for tomatoes preservation treatment using Eco-enzyme.

“…Bioavaibilitas merupakan ketersediaan sejumlah logam yang dapat diserap oleh hayati. Semakin tinggi tingkat bioavailabilitas logam berat dalam tanah, semakin tercemar tanaman yang tumbuh pada tanah tersebut (Widaningrum et al, 2007). Bioavailabilitas logi am berat ditentukan dengan metode ekstraksi bertahap.…”

Kintamani dikenal sebagai pusat penghasil buah jeruk siam di Bali. Berbagai usaha dilakukan oleh para petani untuk meningkatkan produksi buah jeruk siam tersebut, salah satunya adalah dengan mengaplikasikan agrokimia. Akan tetapi, penggunaan agrokimia secara intensif tanpa kontrol yang memadai, dapat meningkatkan kandungan logam-logam berat dalam tanah pertanian, seperti yang telah dilaporkan oleh beberapa peneliti. Keadaan ini tentu dapat juga terjadi pada tanah perkebunan jeruk di Daerah Kintamani-Bali. Penelitian ini bertujuan untuk menentukan konsentrasi logam Pb dan Cd total dalam tanah dan buah jeruk siam serta tingkat bioavailabilitas logam berat tersebut dalam tanah perkebunan jeruk di Daerah Kintamani. Metode ekstraksi bertahap digunakan untuk penentuan konsentrasi logam total Pb dan Cd serta bioavailabilitasnya. Hasil penelitian menunjukkan bahwa konsentrasi Pb dan Cd total dalam tanah sebelum tanaman jeruk berbunga berturut-turut pada kisaran 344,0007-381,4229 mg/kg dan 3,6400-5,3236 mg/kg. Akan tetapi, konsentrasi logam Pb dalam tanah saat panen jeruk mengalami kenaikan menjadi 498,8548-514,3733 mg/kg, sedangkan logam Cd mengalami penurunan menjadi 2,7658-3,4094 mg/kg. Dalam buah jeruk ditemukan bahwa konsentrasi logam Pb dan Cd berturut-turut: 18,3048-24,2205 mg/kg dan 12,3983-15,9922 mg/kg. Konsentrasi ini melebihi ambang batas menurut Peraturan BPOM No. 5 Tahun 2018. Bioavailabilitas logam Pb pada tanah sebelum tanaman jeruk berbunga di setiap lahan sebagian besar berpotensi bioavailable dengan persentase rata-rata sebesar 49,35%. Berbeda dengan Pb, bioavailabilitas logam Cd yang ditemukan dalam tanah di lahan 1 dan 3 adalah Cd yang bioavailable yaitu sebesar 43,57% dan 39,09%, sedangkan di lahan 2 adalah non bioavailable dengan persentase sebesar 41,33%. Kata Kunci: bioavailabilitas, jeruk siam, logam berat. ABSTRACT Kintamani is known as the center of Siamese citrus production in Bali. Various efforts have been made by farmers to increase the production of Siamese citrus fruits, one of which is by applying agrochemicals. However, intensive use of agrochemicals without adequate control can increase the content of heavy metals in agricultural soils, as has been reported by several researchers. This situation can certainly also occur in the soil of citrus plantations in the area of Kintamani-Bali. This study aimed to determine the concentration of total Pb and Cd metals in the soil and citrus fruits as well as the level of bioavailability of these heavy metals in the soil. The sequential extraction method was used to determine the total metal concentrations of Pb and Cd and their bioavailability. The results showed that the total Pb and Cd concentrations in the soil before flowering citrus plants were in the range of 344,0007-381,4229 mg/kg and 3,6400-5,3236 mg/kg, respectively. However, the concentration of Pb in the soil during citrus harvest increased to 498,8548-514,3733 mg/kg, while Cd decreased to 2,7658-3,4094 mg/kg. In citrus fruits, it was found that the concentrations of Pb and Cd were 18,3048-24,2205 mg/kg and 12,3983-15,9922 mg/kg, respectively. This concentration exceeds the maximum allowed according to BPOM Regulation No. 5 of 2018. The bioavailability of Pb in the soil before the citrus plants flowered in each field was potentially bioavailable with an average percentage of 49,35%. In contrast to Pb, the bioavailability of Cd found in the soil of fields 1 and 3 was Cd which was bioavailable, with an average of 43,57% and 39,09%, while in field 2 it was non-bioavailable with a percentage of 41,33%. Keywords: bioavailability, heavy metals, siamese citrus.

“…There wasn't Cd found in the vegetable samples, it was suspected that the soil in which the vegetable is grown did not contain Cd. In addition, the abundance of Cd in nature is also relatively very small [18]. Cadmium is a heavy metal that has received a lot of attention from the public and the environment.…”

Utilization of ex-tin mining land as agricultural land is thought to have the potential to contribute heavy metals in agricultural products. The research objective was to obtain data on the metal content of Pb, Cd, and Sn in various vegetable crops such as spinach, cucumber, tomato, cayenne pepper, bitter guard, eggplant, pumpkin, and pepper. In addition to obtaining data on bioconcentration factors (BCFs) of metals in various vegetables. Vegetables were obtained from ex-mining vegetable fields in Jelitik Village, Gunung Pelawan, and Rebo Village, and metal measurements used Analytical Flame Atomic Absorption Spectrophotometry (F-AAS) Jena ContrAA 300. The results showed that the Sn metal in all vegetables analyzed ranged from 4.71 -10.86 mg/kg, Pb ranged from 0 – 5.0 mg/kg, and Cd metal was not found in all the vegetables and soil samples analyzed. The highest of Sn was found in spinach, and Pb in pepper. Generally, the Pb, Cd, and Sn content in vegetables still meets the Indonesian National Standard (SNI) No. 7387:2009, because not exceed the recommended quality standards. Soil from the three villages of ex-tin mining is not categorized as polluted with Pb, Cd, and Sn metals because it does not exceed the target values recommended by WHO. The TFs (Transfer Factors) value of metals in all types of vegetables analyzed was < 1, meaning that the ex-tin mining lands in Jelilik Village, Gunung Pelawan, and Rebo Village, Bangka are still relatively safe for growing vegetables because they do not contribute to the pollution of Pb, Cd, Sn.
