Background: Land clearing disputes between communities and foreign investors for gold mining. Where in the end the community chose to open small-scale gold mining lands that only utilized spindles and mercury as amalgam with insufficient knowledge in the use of mercury and the processing of the resulting waste. Situation analysis: Residual mercury from the waste of each log averaged 0.03782 mg/L. The management of waste from logs containing mercury is not anti-absorbent and is left to dry on its own. Lack of concern for waste management is caused by a lack of knowledge about the dangers of mercury. The river water flow in Mitra Village comes from Tetanggga Village which has the same activities. Problems: The waste is allowed to dry on its own causing soil pollution, mercury levels in the river are 0.002 mg/L which exceeds the standard, and there is a lack of public knowledge about the dangers of mercury. Solution: Provide education through counseling on the impact of mercury, training on the manufacture and application of filtering tools and phytoremediation methods. Construction of permanent settling tanks and shelters so that they become anti-absorptive. Conclusion: As many as 94.4% had very good knowledge and 5.56% had good knowledge after conducting counseling on the impact of mercury and 2 logs which were being built with permanent anti-absorptive settling tanks and holding tanks.

Traditional mining business activities for processing gold ore in Lantung District are amalgamated using mercury (Hg) from 2015 to 2021 and are still ongoing. On average, there are ten to fifteen logs in each village, the waste being discharged only through ditches or small streams leading to rivers. Mercury that enters the aquatic environment will experience precipitation, dilution, and dispersion, absorbed by organisms living in these waters. Mercury water will be converted into methyl mercury by certain bacteria called biomethylation. In methyl-mercury (MeHg), mercury has toxic properties, firm binding, and high solubility. If consumed by biota, it will experience bioaccumulation in the body, and if consumed by humans for a long time, it can cause various types of diseases up to death. This study aims to determine mercury levels in the rivers and wells of residents in Sepukur Village and Lantung District. The research method is a survey with a sampling technique that is purposive sampling based on the distance from the logs to the residents' wells and rivers. The results showed that mercury levels in the Padesa Village river and springs were 0.002 mg/L. The average mercury level in the Sepukur Village River is 0.0004 mg/L, dug wells are 0.0014 mg/L, and drilled wells are 0.0024 mg/L. It can be concluded that the mercury levels in the springs in the village of Sepukur exceed the standard, and the river is classified in class 3. Mercury levels in the drilled wells of the residents of Sepukur Village exceed the standard, and the dug wells are still within the safe limits of the standard. Meanwhile, the river level in the Village of Sepukur is still relatively safe.

Bayi dan Balita yang mengalami gizi kurang dan gizi buruk beresiko tiga kali menderita stunting jika tidak segera ditangani dengan baik. Ketidakberhasilan program percepatan penanggulangan stunting di NTB disebabkan adanya kerterbatasan kapasitas penyelenggaraan program stunting disamping keterlibatan masyarakat yang masih sangat terbatas. Tujuan penelitian untuk mengetahui pengaruh intervensi kelas gizi dengan pendekatan interprofessional  collaboration  (IPC) terhadap peningkatan tinggi badan (TB) dan berat badan (BB) bayi balita berisiko stunting serta pengetahuan ibu tentang stunting. Jenis  penelitian ini adalah pra-eksperimen dengan rancangan penelitian one group pretest-posttest design dengan menggunakan total populasi bayi balita berisko stunting di Desa Poto sebagai sampel, yaitu sebanyak 15 orang. Hasil penelitian ini menunjukkan bahwa pendampingan kelas gizi dengan pendekatan interprofesional collaboration berpengaruh secara signifikan terhadap peningkatan TB (nilai p = 0,000 dan thitung = 7,054 > ttabel = 1,761),  BB (nilai p = 0,000 dan thitung = 6,590 > ttabel = 1,761), dan pengetahuan ibu bayi balita terkait stunting (nilai p = 0,000). Pendampingan kelas gizi dengan pendekatan interprofesional collaboration memiliki efektifitas sedang dalam meningkatkan TB (nilai N-Gain Score = 0,48) dan pengetahuan ibu bayi balita (nilai N-Gain Score = 0,54) serta efektifitas rendah terhadap BB bayi balita beresiko stunting (nilai N-Gain Score = 0,012).
