Abstract

Industrial progress and waste of urban domestic activities have an impact on the Pb heavy metal pollution on the environment, this will have an impact on human health. Pb metal can be overcome with biological methods by utilizing bacteria in reducing Pb metal. The study aimed to obtain the species  of resistant bacterial isolates of Pb metal and determine its characteristics. Sediment and water samples were obtained from the Tallo River. Isolation and selection of Pb metal resistant bacteria were carried out on nutrient agar media is 10 ppm added of PbAgNO3, afterwards the colonies that grew and differed were characterized by morphological morphology and several biochemical tests. The characterization results obtained 8 isolates of Pb metal resistant bacteria consisted of 8 isolates from sediment samples and 3 isolates from water samples. The characteristics of each bacterial isolate on cell morphology are the same and biochemical tests show different results.

Abstract

Cabai merah Capsicum annuum L. merupakan komoditas yang rentan terhadap kerusakan dan mudah mengalami pembusukan oleh jamur karena kadar air yang tinggi sehingga tidak dapat bertahan lama. Penelitian ini bertujuan untuk mengetahui pengaruh edible coating dengan penambahan ekstrak jahe merah dalam menghambat pertumbuhan jamur pembusuk serta mengetahui umur simpan cabai merah. Jamur pada cabai merah diisolasi dengan menggunakan metode penanaman langsung (direct planting) dan diperoleh jamur Aspergillus flavus. Selanjutnya dilakukan uji daya hambat terhadap jamur Aspergillus flavus menggunakan ekstrak jahe merah konsentrasi 5%, 10%, 20% dan 40%. Hasil yang diperoleh menunjukkan ekstrak jahe merah mampu menghambat pertumbuhan jamur Aspergillus flavus serta konsentrasi yang tepat sebagai pengawet adalah konsentrasi 5%. Pengamatan hasil pengaplikasian edible coating dilakukan melalui uji susut bobot, uji tekstur, uji warna dan uji Total Plate Count (TPC). Hasil yang diperoleh menunjukkan pengaplikasian edible coating dengan penambahan ekstrak jahe merah dapat menurunkan susut bobot, memperlambat pelunakan dan mempertahankan warna dari cabai merah dengan jumlah koloni jamur yang relatif sedikit yaitu 2,8 x 102 CFU/mL dibandingkan perlakuan kontrol dengan jumlah koloni jamur 2,3 x 104 CFU/mL. Dari hasil tersebut memperlihatkan edible coating dengan penambahan ekstrak jahe merah dapat memperpanjang umur simpan sampai pada hari ke-9, serta mampu menghambat pertumbuhan jamur pembusuk pada cabai merah.

Abstract

Fermented Virgin Coconut Oil (VCO) is a processed oil where the manufacturing process uses baker's yeast, is easy to make and has simple equipment. The high content of lauric acid and vitamin E is beneficial for skin health, so it is often used as a raw material for making soap. One way to improve the function of VCO is the fortification process with dragon fruit which contains high antioxidants. This activity aims to increase community entrepreneurial interest by utilizing local potential into health and beauty products so that it can improve the family economy. Coconut and dragon fruit are the main raw materials for VCO and VCO soap which are easy to find in Sabila Village, Mallawa District, Maros Regency. Community service activities (PKM) begin with counseling/lectures on sterilization techniques, packaging methods and online product marketing. Followed by training on how to make VCO by fermentation and VCO soap with fortified dragon fruit extract. The results of the activity showed the enthusiasm of the participants during the discussion and the results of the pre- and post-test evaluation showed an increase in participants' knowledge about VCO and VCO soap by 78.0% after the training.
