Abstract

Anoxygenic Photosynthetic Bacteria (APB) has beneficial properties including as probiotic candidates, biofertilizers, bioremediation agents, and can reduce H2S concentrations in waters. However, the APB also has a weakness, slow growth.It is known that the interaction of metal ions and the exposure of magnetic fields increases enzyme activity and growth rates. The aim of this study is to determine the effect of metal ions and the exposure to magnetic fields on APB growth. The APB isolate, AM which is isolated from mangrove roots and tested for its effects on metal ions in seawater complete (SWC) media.The metal ions tested were Cu, Pb, Al and Fe with different concentrations. The metal ion is exposed to a 0.2 mT magnetic field for 10 minutes before being added to the media. The cell count results showed that both metal ions exposed and unexposed to magnetic field did not affect the growth of APB AM isolates. However, the metal ion in SWC media affects the spectra pattern of AM APB isolates.

Abstract

Bakteri penghasil enzim protease memiliki kemampuan untuk melakukan bioremediasi limbah protein. Penelitian ini dilakukan untuk mengetahui aktivitas dan karakterisasi enzim protease dari isolat Bacillus sp. (UJ132) yang diisolasi dari udang pasir (Metapenaeus affinis) di kawasan hutan mangrove Desa Margasari, Lampung Timur. Uji aktivitas enzim dilakukan secara kualitatif dan kuantitatif. Karakterisasi enzim meliputi penentuan suhu dan pH optimum, pengaruh ion logam, serta penentuan Km dan Vmaks. Dari hasil percobaan diketahui bahwa enzim protease dihasilkan pada waktu produksi optimum 18 jam dengan aktivitas protease sebesar 0,09 U/mL. Suhu optimum enzim ini yaitu pada suhu 50°C yang menghasilkan aktivitas sebesar 0,08 U/mL. Enzim protease ini mempunyai kondisi optimum pada pH 5 dengan nilai aktivitas 0,09 U/mL. Semua ion logam (Ca2+, Mn2+, Cu2+, Mg2+) berfungsi sebagai inhibitor kecuali ion Fe3+ yang berfungsi sebagai aktivator pada konsentrasi 1 mM dan 5 mM. EDTA dengan konsentrasi 1 mM dan 5 mM berfungsi sebagai inhibitor pada enzim protease isolat UJ132. Nilai Vmaks enzim protease 0,33 U/mL sedangkan Km senilai 4,59 mg/mL substrat, enzim ini mempunyai afinitas yang tinggi terhadap substrat.Shrimp farming produces protein wastes which mainly come from the remnants of given feed and excreta (feces) of shrimp. Bacteria known to possess protease enzymes have the ability to solve this protein waste problem in the shrimp farming industry. This study was conducted to determine the production and characterization of protease enzyme from Bacillus sp. (UJ132) isolated from the mangrove forest area of Margasari Village of Lampung Timur. The enzyme activity test was done qualitatively and quantitatively. The objectives of this study were to determine the optimum production of the enzymes and observe their characteristics, including determining the temperature and optimum pH, the effect of several metal ions, as well as Km and Vmax. The experimental results revealed that the protease enzyme had an optimum time of 18 hours of protease activity as much as 0.09 U/mL. The optimum temperature of this enzyme was 50°C which produced an activity of 0.08 U/mL. This protease enzyme has an optimum working condition at pH 5 with an activity value of 0.09 U/mL. All metal ions (Ca2+, Mn2+, Cu2+, Mg2+) acted as inhibitors except Fe3 + ions which acted as activators at concentrations of 1 mM and 5 mM. EDTA with a concentration of 1 mM and 5 mM served as an inhibitor of UJ132 isolate protease enzyme. The value of Vmax of the protease enzyme was 0.33 U/mL while Km was 4.59 mg/mL suggesting that this enzyme has a high affinity with the substrate.

Abstract

Minyak jelantah (mijel) is known in Indonesia as waste cooking oil. Even though it is a waste, mijel is still used by consumers for savings. The problem is, if it is used repeatedly more than three times, mijel can cause health problems. In addition to health hazards, if discharged through water channels, it can cause environmental pollution. Lack of public knowledge about the dangers of using the mijel in the end will have a negative impact. To educate the public about the health-risks of using mijel, we held a short training for housewives in Kelurahan Tanjung Agung, Bandar Lampung on July 22, 2020. This training provided the targeted housewives with the knowledge and skills to process the waste cooking oil into laundry soap. The purpose of this activity was to educate and provide training to the community, especially PKK women who interact directly with the use of mijel, about the dangers of mijel and how to manage it. PKK women who participated in the training seemed interested and understood the explanation described, this can be seen from the increase in the average pretest score from 55.7 to 81.3 at posttest. The benefits obtained by the participants are: 1) Understanding that using mijel more than three times can cause health problems for consumers. 2) Processing of waste cooking oil to laundry soap can reduce pollution in the aquatic environment.3) Laundry soap made from waste cooking oil can be a source of family income.

Abstract

The research was conducted in a factorial experiment with factor A: far-red light treatment with 2 levels: control (without far-red light), and treatment (far-red light). Factor B was a time of observation with 3 levels: 4, 6, 8 days after wrapping. Wrapping each detached fruit in a combination of four layers of blue-colored plastic, one layer of green-colored plastic, and two layers of red-colored plastic resulted in a red light treatment. Transmission measurement of that plastic combined with a spectrophotometer at wavelength 700-735 nm was 75%. To deter fresh weight, each fruit was weighted with an analytical balance. Total soluble carbohydrate content was determined by the phenol-sulfuric method and counted based on the glucose standard curve (mg/gram tissue). Analysis of variance was conducted at a 5% significant level, and if the interaction was significant, then continued with simple effect determination at a 5% significant level by the F test. The fresh weight average of the soluble carbohydrate content of treated fruits was higher than the control. The fresh weight of chili fruits was relatively constant during observation of both treated and controlled fruits. The total soluble carbohydrate content average relatively did not differ between treated and control fruits. Total soluble carbohydrate content was increased 6 days after treatment and decreased 8 days after treatment. The result of this research concluded that red light inhibited the ripening process of chili fruits by slowing the decrease of fresh weight.
