Abstract

The high value of COD (Chemical Oxygen Demand) is one of the indicators of the burden of organic substance pollution in the wastewater food flavoring industry. COD values can be lowered by converting to biogas. In this study biogas was made through a two-stage fermentation system. At the first stage organic material is conditioned in an acidic state (pH = 4) with variable fermentation time: 2 days, 4 days, 6 days and 8 days. Then at each time fermented for 18 days at second stages. As a result, the amount of biogas volume produced is the same, namely: 7,5 L. However, the most amount of methane is produced at the time of fermentation phase one for 2 days, namely: 83%. While the lowest value is produced at the time of fermentation phase one for 8 days, namely: 70%. At the time of fermentation phase one for 8 days produced the highest hydrogen composition, namely: 9,023 %. The composition of methane at stage one for 4 days produces a higher value, namely: 81.431% compared to the single stage fermentation system, namely: 78.9 %.

Abstract

Abstract Traditional medicine such as saffron-colored rice is still in great demand in Indonesia. If the production process is not carried out in accordance with the method of making and processing herbal medicine, it can cause microbial contamination. The preparation of herbal medicine must meet the requirements for the Total Plate Number (ALT). The aimof this study was to determine the amount of microbial contamination in the liquid herbal rice kencur which is produced by the traveling herbal medicine seller. The study used an experimental method using samples of saffron-colored rice (A, B, and C). Microbial testing went through the stages of homogenization, dilution, mixing with the mediumsnd incubation. Homogenization was initiated by adding 25 ml sample with 225 ml 0.1% Buffered Peptoned Water with a stomacher for 2 minutes. Suspension dilution was carried out in order to obtain colonies that grew separately so that they were easy to count. Mixing with the medium is done by pour plate inoculation method. The solid medium used for ALT is Nutrient agar. Based on the results of the study, the ALT results were obtained, sample A  2.2 x 104 colonies/ml, sample B 2.6 x 104 colonies/ml, and sample C 8.0 x 107 colonies/ml. The results are not in accordance with the requirements stated in the Regulation of the Head of the Drug and Food Control Agency of the Republic of Indonesia Number 12 of 2014 about Quality Requirements for Traditional Medicines.AbstrakObat tradisional seperti jamu beras kencur masih banyakdiminati di Indonesia. Apabila proses produksinya dilakukantidak sesuai dengan cara pembuatan dan pengolahan jamu dapat menyebabkan terkontaminasi mikroba. Penyediaanjamu harus memenuhi syarat Angka Lempeng Total (ALT). Penelitian ini bertujuan untuk mengetahui jumlah cemaranmikroba dalam jamu beras kencur sedian cair yang di produksi oleh penjual jamu gendong keliling. Penelitianmenggunakan metode deskriptif dengan menggunakan sampel jamu gendong beras kencur (A, B, dan C). Pengujianmikroba melalui tahap homogenisasi, dilutasi, pencampurandengan medium, inkubasi dan interpretasi hasil.Homogenisasi sampel diawali dengan sebanyak 25 ml sampelditambahkan 225 ml Buffered Peptoned Water 0.1% dan dikocok dengan stomacher selama 2 menit. Dilutasi suspensidilakukan agar memeroleh koloni yang tumbuh secaraterpisah sehingga mudah dihitung. Pencampuran dengan medium dilakukan dengan metode inokulasi pour plate. Medium padat yang digunakan untuk ALT adalah Nutrient agar. Berdasarkan hasil penelitian didapat hasil ALT yaitu, sampel A 2,2 x 104 koloni/ml, sampel B 2,6 x 104 koloni/ml, dan sampel C 8,0 x 107 koloni/ml. Hasilnya tidak sesuaidengan persyaratan yang tertera pada Peraturan Kepala Badan Pengawasan Obat dan Makanan Republik Indonesia Nomor12 Tahun 2014 tentang Persyaratan Mutu Obat Tradisional.

Abstract

Plastic is a political agenda that always ranks at the top in several countries. Several efforts have been made, starting from studies, providing education, and to producers and consumers to save the environment. The COVID-19 pandemic has disrupted plastic reduction policies covering personal protective equipment (PPE), plastic bags, etc. from regional to national levels, which resulted in significant changes in managing plastic wastes and the negative impacts on the environment and human health. This paper explores the readjustment of policies during the COVID-19 pandemic and its potential implications to the environment. The sudden increase in plastic waste due to the COVID-19 pandemic indicates the importance of strengthening plastic reduction policies, thereby making room for technological innovation to achieve a green economy and provide policy recommendations for future research directions.
