Cenil is still one of the traditional foods that people are interested in nowadays. To make it look attractive, cenil producers often use red coloring substance such as Rhodamine B. Rhodamin B is one type of textile dye that is prohibited from being used in food. Many cases of food poisoning or illness are caused by insecure food consumed, lack of application of hygiene sanitation and the use of hazardous chemical dyes as additional ingredients in Cenil. This research used descriptively with quantitative approach. The population of the study was the producer of the cenil as many as seven producers that are selling at the spread in 4 traditional markets in 3 sub-district of Jember District. The sample in this study is total population. The result of the knowledge level of cenil respondents related to the use of additives dye has a medium category (57%). The result hygiene sanitation of cenil has a good selection quality (57%). The result of a laboratory test to the existence of Rhodamin B dye on cenil showed two samples (29%) which contain positive Rhodamin B. Identification the difference of cenil which containing Rhodamine B have bright pink color, tend to fluoresce, there are nonhomogeneous color spots and bitter taste.

A plate stone mining is one of the mining activities in the district of  Jember.This mining is becoming a major commodity for competing in foreign markets (exports).  A plate stone that has been processed then utilized to furniture, tables, chairs, decorate walls, and  fences. plate Stone is widely used in Japan for house building because it is considered strong and safe from earthquake. The purpose of this study was to determine how the impact of plate stone mining on the environment and public health. This research was a quantitatif descriptive and the population of this study were all stone miners for sample of 33 respondents. Sampling was carried out by using a purposive sampling technique. Variabel studied are the Characteristics of respondents, the Habit ofusing of Personal Protective Equipment, the continuity of the use of masks, working period, work duration, plate stone processing  and on an environment impact.  The Results of this study was the number of sex workers male 51.5% and female of 48.5%. As for the age of majority aged between 31-40 years, working period <5 years of 57% with work duration <8 hours /days of the 93%. The process of manually plate stone processing and the impact of mining is changing the of nature. Suggestion of this research is the need for a supervision of government agencies that deal with health and safety.

Aktivitas TPA dapat mencemari lingkungan sekitar, logam berat adalah cemaran yang berbahaya bagi lingkungan. Kulit pisang kepok dari Kabupaten Jember mengandung selulosa 55% yang memungkinkan dapat  mengikat  logam berat Pb. Tujuan penelitian ini yaitu menganalisis perbedaan kadar Pb pada kelompok tidak diberi perlakuan penambahan massa arang aktif kulit pisang 0g/200ml (P0), dengan air sumur yang diberi perlakuan penambahan massa arang aktif kulit pisang 2g/200ml (P1), 3g/200ml (P2), dan 4g/200ml (P3) dengan air sumur yang mengandung Pb selama 10 menit. Penelitian ini merupakan True Experiment dengan menggunakan metode Rancangan Acak Lengkap (RAL) dengan enam pengulangan. Setiap sampel dikontakkan air yang mengandung Pb, diaduk menggunakan magnetig stirrer dengan kecepatan 300 rpm selama 10 menit, kemudian dilakukan penyaringan menggunkaan kertas saring untuk memisahkan arang dengan air. Data dianalisis dengan kolmogorof smirnof dilanjutkan dengan menggunakan uji statistik One Way Anova. Hasil menunjukkan terdapat perbedaan penurunan kadar Pb yang signifikan antara kelompok kontrol (P0), dan kelompok-kelompok perlakuan penambahan arang aktif kulit pisang kepok (P1=0,000; P2=0,000; P3=0,000). Arang aktif kulit pisang kepok terbukti secara signifikan dapat mengikat timbal (Pb) dalam air.

Amalgamation in the activities of gold processing produces liquid waste containing heavy metals mercury (Hg). Pistia stratiotes is a floating plant that has high adaptability to climate, rapidgrowth rate, and huge nutrients and water absorption.So that, it is possible to be used as phytoremediation plant for absorbing Hg in water. The purpose of this true experiment research wasto analyze the Hg concentration differences between waste water with and without Pistia stratiotes of 300 gr/ 6 l, 400 gr/ 6 l and 500 gr/ 6 weight in 10 days contact time. The data were analyzed by using One Way Anova test at ? = 0,05. The results showed significant differences ofHg levels between control and treatment groups (p<0,05), and 500 gr/6 l Pistia stratiotes weightgave the highest reduction of Hg level in liquid waste, i.e. 77,6 %. It can be concluded that Pistia stratiotes can be used as phytoremediation plant for Hg metal. However, it is necessary todo further research by adding contact times as variable, so that the absorption rate at each timecan be determined.
