Abstract

Electroplating process has a negative effect in form metal ions waste. Today, industrial wastewater treatment widely using aluminum sulfate or alum as synthetic coagulants, although hazardous and expensive. This study was conducted to discover the activity of Moringa seeds (Moringa oleifera) as natural coagulants to substitute synthetic coagulants. Trapped metal ions detected by ICP-OES. The results showed that moringa seed coagulants could reduce 53% Cr, 64.56% Mn, and 92.89% Pb in the addition of 15 grams of moringa seed coagulants.

Abstract

Kolesterol, lipid penting untuk proses metabolisme, memegang peran penting dalam tubuh manusia. Namun, kelebihan kolesterol berpotensi menghambat fungsi otak secara optimal. Penelitian ini berupaya untuk meneliti ekstrak daun bidara, menggunakan pelarut n-heksana, dengan tujuan khusus untuk menilai kemanjurannya dalam mengurangi kadar kolesterol. Analisis fitokimia daun bidara mengetahui adanya alkaloid, steroid, dan tanin. Khususnya, kandungan senyawa fenolik yang melekat pada daun bidara muncul sebagai kandidat yang menjanjikan sebagai agen anti kolesterol. Temuan empiris ini memperkuat kemanjuran ekstrak daun bidara, yang memanfaatkan pelarut n-heksana, dalam menurunkan kadar kolesterol sebesar 70,4023%.

Abstract

The Pirdot plant (Saurauia vulcani Korth) is a wild plant that grows abundantly in tropical regions such as in North Sumatra. The active compounds found in Pirdot plant leaves are known to have good antioxidant activity. The aim of this research is to evaluate the n-hexane and methanol extracts of Pirdot plant leaves in inhibiting oxidation in crude palm oil (CPO). In this study, the Pirdot plant leaves were extracted using n-hexane (EHP) and methanol (EMP) solvents. The effectiveness of adding both extracts to the quality of CPO was tested for eight days using the parameters of free fatty acid content and peroxide value. The results of the effectiveness test for adding both extracts to CPO showed a good inhibitory effect on the oxidation reaction in CPO. The EMP extract at a concentration of 5000 ppm was more effective in maintaining the quality of CPO for 8 days, with a free fatty acid content of 3.09% and a peroxide value of 14.03 meq O2/kg.

Abstract

Organic waste from traditional markets and households represents a significant environmental challenge but also offers potential as a renewable energy source through biogas production. This study aimed to evaluate the chemical composition and gas production potential of organic waste collected from Keranggot Market and household sources in Cilegon City. Proximate analysis was conducted to determine pH, moisture content, crude fiber, fat, carbohydrate, and protein levels, while total organic carbon (TOC) was measured using the dry combustion method. Gas composition (N₂, O₂, H₂, CH₄, and CO₂) was analyzed by gas chromatography after storage in drum containers for one and two weeks. The results showed that the waste samples had an acidic pH (5.18), high moisture content (3.00%), high crude fiber content (55.01%), moderate fat (6.76%) and protein levels (5.56%), and a total organic carbon content of 19.11%. The calculated C/N ratio was approximately 21.5, which falls within the optimal range for anaerobic digestion. Gas analysis revealed the presence of methane (1.10%) and carbon dioxide (6.71%) after two weeks of storage, confirming the onset of anaerobic decomposition. These findings suggest that organic waste from Keranggot Market and household sources in Cilegon City has potential as a feedstock for biogas production, although pretreatment may be required to overcome the high lignocellulosic content.

Abstract

One plant with potential to treat skin diseases is the Kesambi plant. Based on community experience in Cilegon, a decoction of Kesambi tree bark has been used to treat skin ailments, including itching, insect bites, and scabies. This research aims to reveal the potential of ethyl acetate extract from the tree bark as a standardized ointment preparation. Extraction was performed using the maceration method. Quality testing of the ointment included antibacterial, safety, stability, organoleptic, and bioactive compound content testing. The best formulation was formulation 1, with an antibacterial inhibition zone of 0.6-0.7 mm, classified as moderate. Increasing the amount of extract did not significantly affect antibacterial activity. The bioactive compound content in the ointment consisted of compounds from the groups of triterpenoids, steroids, phenolics, and flavonoids.

Abstract

Research on drug delivery systems continues to develop, including making the latest formulations on capsule shells as a medium for drug delivery. The effort that has been done was developing non-gelatine drug delivery materials made from the combination of seaweed and cactus. The main component in making gel on seaweed and cactus is the polysaccharide pectin. This study aims to make and determine the characterization of capsule shells from a combination of seaweed and cactus. Capsule shells are made from a combination of pectin extracts from seaweed and cactus with 5 different ratios of 0:4 (A), 1:3 (B), 2:2 (C), 3:1 (D), and 4:0 (E). The characterization involved weight uniformity test, disintegration time test, water swelling test, and dissolution test. Pectin from green seaweed and koboi cactus weighed 235 g and 75 g. The capsule shell weights based on Farmakope Indonesia sixth edition were 307.2, 311.6, 309.7, 304.6, and 308.7 mg. The capsule shell disintegration times, based on Farmakope Indonesia sixth edition, 2020, were 15,16, 14, 21, and 12 minutes, and the best result of the water swelling test was C capsule (2:2) of 666.7%. The results of the capsule shell dissolution test showed that the reduction of the capsule shells did not exceed 10% for 30 minutes according to the Farmakope Indonesia sixth edition. The capsule shells made from a combination of seaweed and cactus can be used as material in drug delivery systems. Non-gelatinized capsule shell which is expected to have anti-inflammatory activity.
