Pengolahan dan Uji Kualitas Pupuk Organik Feses Sapi (Bos Taurus) dan Enceng Gondok (Eichhornia Crassipes) terhadap Pertambahan Tanaman

Usually, the people of Mojopetung Village, Dukun Subdistrict, Gresik Regency in disposing of waste from livestock are left idle in the ground if dried cow feces will be dumped into the rice fields. If in the rainy season the cattle fases will disappear by itself because it is carried by running water and the cow feces seep into will also flow into the river directly. This causes the water to not function properly and cause air and soil pollution. In addition, aquatic biota life is also disturbed not only because of cow feces (Bos taurus) but the existence of Eichhornia crassies which continue to increase people's habit does not use water as they should use as a place of animal baths. These problems can be overcome by processing cow feces with water hyacinth as compost. With the method of applying the fertilizer directly to plant. The method of data analysis was carried out using one-way ANOVA (Analysys of Variance) Test to find out whether or not the influence of organic fertilizer on plant growth. The results showed that the average height of the stem was 32.69 cm in the treatment using compost, 30.84 cm using urea fertilizer, 25.8 cm without fertilizer. The number of leaves that use compost, urea or no fertilizer results in an average value equal to 5 cm, and the leaf color produces a green average for each experiment. ANOVA test on plant growth results in F = 14.608> F table = 3.59. This shows that there are significant differences in plant growth in organic fertilizer applications. the number of leaves and the color of the leaves yielded F = 0 <F arithmetic = 3.59 and F = 0.2 <F arithmetic = 3.59 which showed no significant difference in the number of leaves and plant height.

Dampak Lingkungan Terhadap Kejadian Infeksi Parasit

Penyakit infeksi parasit masih menjadi masalah kesehatan di Indonesia dan di dunia. Pada tahun 2017, World Health Organization (WHO) memasukkan beberapa penyakit parasit ke dalam Neglected Tropical Disease (NTD). Penyakit parasit tidak dapat lepas dari kondisi lingkungan, suhu, kelembaban, iklim, dll. Di Indonesia, masih sedikit artikel yang meninjau dampak lingkungan terhadap insiden infeksi parasit. Tujuan dari penulisan artikel ini adalah untuk membahas bagaimana suhu, kelembaban dan cuaca dapat memengaruhi angka prevalensi penyakit akibat parasit.

Pengolahan Limbah Cair Domestik Pada PMKS PT Sisirau di Kabupaten Aceh Tamiang

Air buangan dari kegiatan rumah tangga atau disebut limbah cair domestik pada perumahan di sekitaran PMKS berpotensi menjadi salah satu sumber pencemaran lingkungan jika tidak dilakukan pengolahan secara benar. Penelitian ini bertujuan untuk memantau aktivitas pengolahan limbah cair domestik pada PMKS (PT Sisirau) Kabupaten Aceh Tamiang. Penelitian menggunakan metode grab sampling. Parameter pengamatan dari sampel air buangan pada perumahan pabrik adalah kadar pH, BOD, COD, TSS, ammoniak, minyak dan lemak. Data yang diperoleh dianalisa dengan membandingkan hasil yang diperoleh sesuai Permen LH dan Kehutanan RI No. P.68/Menlhk/Setjen/Kum.1/8/2016. Hasil penelitian menunjukkan bahwa limbah cair domestik di PMKS PT Sisirau sudah memenuhi standar baku mutu kualitas limbah cair yang aman di buang ke badan air yaitu nilai pH, BOD, COD, TSS, ammoniak, minyak dan lemak berturut-turut adalah 8,02; 23,9mg/L; 50,99mg/L; 25mg/L; 0,29 mg/L; dan < 2mg/L. Nilai-nilai ini berada dibawah kadar maksimum standarisasi.
