Shigella dysentriae is a bacterial species of shigella that occurs in tropical countries, these bacteria are pathogenic gut bacteria are commonly known to cause dysentery. Dysentery is an infection that causes sores that cause ulcers limited dicolon characterized by symptoms known as dysentery syndrome. In user of trimatoprim sulfametaksazol can cause or accelerate the onset of megaloblastosis, leocopenia, or trombostopenia. In regular use, this combination appears to show little toxicity, approximately 75% of these adverse effects involving the skin. "Pandan wangi" (Pandanus amaryllifolius roxb) is one of the plants that can be used as a natural antibiotic against Shigella dysentriae infection because the content of fragrant pandan leaves include flavonoids, alkaloids, saponins and tannins. This type of research is experimental, while the goal is to determine the effect of "pandan wangi" leaf (Pandanus amaryllifolius roxb) juice on Shigella dysentriae. Consisting of 7 concentrations and four repetitions. Using dilution method by observing the growth of bacteria Shigella dysentriae on "pandan wangi" leaf juice that is characterized by the colonies grown on media Mac Conkey (MC). Data analysis uses Anova with an error or a = 5%. The advanced test uses Tukkey test, Honestly Significant Difference (HSD). After doing the research, the optimal concentration of juice of "pandan wangi" (Pandanus amaryllifolius roxb) leaves can inhibit Shigella dysentriae is 25% and can kill Shigella dysentriae from concentration of 50%. The final conclusion is that there is the effect of "pandan wangi" (Pandanus amaryllifolius roxb) leaf juice on Shigella dysentriae. Keywords: Pandanus amaryllifolius Roxb leaves, Shigella dysentriae. PENDAHULUAN Disentri basiler endemik disebabkan olehShigella dysentriae dan terutama di Negara tropis.

Makanan dan minuman yang dikemas dalam kaleng memiliki kemungkinan untuk terkontaminasi logam berat yang berasal dari komponen penyusun kaleng. Kontaminasi logam berat bisa menyebabkan keracunan dan berbahaya bila masuk ke dalam system metabolism tubuh dengan jumlah yang melebihi batas yang telah ditetapkan dalam SNI dan BPOM. Penelitian ini bertujuan untuk menganalisa Timbal (Pb), Kadmium (Cd) dan  seng (Zn) pada sarden, kornet, susu kaleng, sari buah, minuman berkarbonasi. pengambilan sampel dilakukan di dua lokasi berbeda yaitu pasar modern dan pasar tradisional, dengan tujuan agar dapat membandingkan perbedaan pada pasar modern dan pada pasar tradisional.Serapan logam diukur dengan menggunakan spektofotometri serapan atom (SSA) pada gelombang yang spesifik. Hasil penelitian adalah kadar cadmium (Cd) tidak teridentifikasi, kadar logam Timbal (Pb) pada sampel makanan dan minuman kaleng adalah 0.01 mg/kg, 0.018 mg/kg, 0.026 mg/kg, 0.012 mg/kg, 0.027 mg/kg, 0.027 mg/kg, 0.018 mg/kg, 0.015 mg/kg, 0.024 mg/kg dan 0.019 mg/kg, sementara itu cemaran Zn  adalah 0.188 mg/kg, 0.169 mg/kg, 0.193 mg/kg, 0.184 mg/kg, 0.129 mg/kg, 0.105 mg/kg, 0.107 mg/kg, 0.098 mg/kg, 0.176 mg/kg, 0.152 mg/kg. Semua sampel makanan dan minuman kaleng tidak ada yang melebihi batas maksimum cemaran yang telah di tetap kan dalam SNI dan Badan Pengawas Obat dan Makanan. Kadar cemaran logam berat Pb dan Zn pada sampel makanan dan minuman kaleng dari pasar tradisional lebih tinggi daripada sampel makanan dan minuman kaleng dari pasar modern              Kata kunci : Makanan-Minuman Kemasan Kaleng, SSA, Timbal, kadmium, seng

Used cooking oil is the remaining cooking oil from the frying process. The use of cooking oil repeatedly at high temperatures and for a long time causes the peroxide number to increase. High peroxide levels can present a health hazard. Phenolic and flavonoid content contained in sweet orange peel is an antioxidant that acts as an antidote to free radicals so that it can slow down the oxidation of used cooking oil. The purpose of this study was to determine the effectiveness of the long soaking time of the sweet orange peel powder (Citrus sinensis) on the peroxide number in used cooking oil. This type of research is experimental with the number of sample repetitions for each treatment, namely 25 samples. The formulation of the problem of this research is whether there is an effect of the effectiveness of the long soaking time of the sweet orange peel powder (Citrus sinensis) on the peroxide number in used cooking oil. From the results of the examination, the average levels of peroxide numbers in used cooking oil that had been soaked were 1 day 22.7949 mEq, 2 days 19.5965 mEq, 3 days 13.5975 mEq and 4 days 9.5984 mEq. Statistical analysis using ANOVA showed the effect of the effect of soaking duration of sweet orange peel powder (Citrus sinensis) on the peroxide number in used cooking oil p (sig) = 0,000 which is less than 0.05.  Keywords:  Sweet Orange, Peroxide Number, Used Cooking Oil.

Physically, used cooking oil, which is an oil that has been damaged, can be seen from its brown color, rancid smell, thick, foamy and has a high free fatty acid content. This study aims to determine the potential effect of kepok banana peels (Musa acuminata balbisiana Colla) on free fatty acid levels in used cooking oil. The study used an experimental research design. Free fatty acid was measured by titration with the Alkalimetric method and expressed in percent.The mean free fatty acid level in used cooking oil without kepok banana peel powder was 0.993%, the mean free fatty acid content in used cooking oil with the application of kepok banana peel powder of 0.095%. After giving kepok banana powder, used cooking oil decreased rancidity, the color of brown cooking oil was brighter, the smell was fresher, indicating that there was a potential effect of kepok banana peel on free fatty acid levels in used cooking oil. There was a difference in the free fatty acid content of used cooking oil when kepok banana peel powder was administered (p=0.000).Administration of kepok banana peel powder affected reducing free fatty acid levels in used cooking oil.

Dengue Hemorrhagic Fever (DHF) is a disease caused by ectoparasites. The ectoparasite in this disease is the Aedes aegypti mosquito which acts as a vector. Aedes aegypti is a type of mosquito that can carry the dengue virus that causes dengue fever. The symptoms of this disease are rarely noticed and can spread quickly. In addition, this disease also attacks all ages and can cause death. Cymbopogon nardus (L.) Rendle is an aromatic grass from the Poaceae family that produces essential oil mainly in the leaves. The essential oil from C. nardus is known as citronella oil has repellent activity. To determine the effect of citronella powder (Cymbopogon nardus) as activated charcoal packaged in bags for controlling Aedes aegypti in bathroom tubs. This study is an experimental posttest-only control group design consisting of a control group and a treatment group using activated charcoal from lemongrass at a concentration of 1%, 2%, and 2.5%, which was treated on Aedes aegypti mosquito larvae instar III five times test. Data analysis used the One-way Anova Statistical Product and Solutions (SPSS) Version 26 test. The results showed the effect of citronella powder (Cymbopogon nardus) as activated charcoal on the mortality of the third instar Aedes aegypti mosquito larvae. This is indicated by the p-value of 0.197. The high concentration of activated charcoal from lemongrass powder determines the high mortality of third instar Aedes aegypti larvae. This is indicated by the significant difference between the concentration treatments. For further research, an increase in the concentration of activated charcoal is needed to increase larval mortality.
