Abstract

The Bestari Landfill of Probolinggo City collects a variety of plastics waste, most of it already in a degraded state. It is estimated to be potential habitat for polypropylene-degrading bacteria. Previous NGS studies identified 2,400 species of bacteria, but did not reveal their physiological and functional characteristics. This study aims to identify PP-degrading bacteria using 16S rRNA analysis. Isolation is carried out by the Enrichment method on Mineral Salt Media (MSM) containing PP granules. The research stages included sampling, isolation, and screening of bacteria for the most effective degrading agents. Six isolates of polypropylene-degrading bacteria were discovered at the Bestari Landfill of Probolinggo City, including B1UM1, B1UM2, B1UM3, B2UM1, B2UM2, and B2UM3. After 15 days of incubation, potential isolates B1UM1, B1UM2, and B2UM1 showed the highest polymer reduction of 8.25%, 7.15%, and 6.25%. Gram staining results showed that isolate B1UM1 was coccus and a Gram-positive bacterium, while isolates B1UM2 and B2UM1 were basil and Gram-positive. Genotypic identification through 16S rRNA sequence analysis showed that isolate B1UM1 had 100.0% similarity with Staphylococcus haemolyticus, BIUM2 had a 100% similarity to Bacillus cereus, and B2UM1 had a 99% had a similarity to Bacillus sp.

Abstract

Pineapple peel waste is an abundant agricultural residue that remains underutilized. This study aims to produce liquid organic fertilizer (LOF) from pineapple peels using EM4 bioactivator, cow manure, rice-washing water, and palm sugar through a 30-day fermentation process. Fermentation performance was monitored via daily temperature and pH, along with nutrient content analysis including nitrogen (N), phosphorus (P), potassium (K), and organic carbon (C-organic). The results showed temperature ranged from 27.9–32.3°C and pH between 3.0–4.0, within the optimal range for microbial activity. However, nutrient concentrations of N (0.153%), P (0.116%), K (0.105%), and C-organic (1.58%) did not meet the Indonesian National Standard (SNI 261/2019). This indicates that pineapple peel alone requires nutrient-rich additives to produce standard-compliant LOF. This study highlights the potential of pineapple peel waste as an eco-friendly LOF source, emphasizing the need for further formula optimization.

Abstract

This study quantified and compared the ascorbic acid content in green and red bird's eye chili (Capsicum frutescens) using UV-Vis spectrophotometry. The method was optimized by determining the maximum wavelength of ascorbic acid in an acid-stabilized solution, found to be 231 nm. A calibration curve was constructed with standard solutions (25-100 ppm), yielding a linear equation y = 0.0514x + 0.6032 (R² = 0.9361). Sample extracts were prepared and analysed in triplicate at this wavelength. The results demonstrated a significant difference in ascorbic acid concentration between the two varieties. The red chili exhibited a higher concentration of 34.39 ppm in the measured solution, corresponding to 0.90% (b/b) of the fresh weight. In contrast, the green chili contained 23.95 ppm (0.60% b/b). This indicates a 50% higher ascorbic acid content in the mature red fruit. The study concludes that ripening significantly enhances the vitamin C content in bird's eye chili, and the red variety is a nutritionally superior source. The validated method proved effective for the quantitative analysis of ascorbic acid in complex food matrices.

Abstract

Detergent wastewater contains high levels of surfactants, particularly Linear Alkylbenzene Sulfonate (LAS), which are persistent and harmful to aquatic ecosystems. This study evaluated the potential of Moringa oleifera seed extract (MOS) as a natural coagulant for detergent wastewater, compared with alum as a synthetic coagulant. The coagulation process was carried out using the jar test method at varying dosages (100–1500 mg/L) and pH levels (4–9). Turbidity was measured following SNI 06-6989.25-2005, while LAS concentration was analysed using the Methylene Blue Active Substances (MBAS) method. Results showed that MOS achieved optimum performance at 1500 mg/L and pH 4, with a turbidity removal efficiency of 94.96% (final turbidity 4.76 NTU) and LAS removal efficiency of 88.94% (final concentration 0.58 mg/L). In comparison, alum reached its optimum at 200 mg/L and pH 6, with lower LAS removal efficiency. Validation with wastewater samples stored for 1–3 nights indicated that MOS maintained consistent performance, while alum showed fluctuating results. An in-silico docking study further confirmed the molecular interaction between LAS and MOS proteins, with a binding energy of –4.8 kcal/mol, supporting the observed experimental results. These findings demonstrate that MOS is a promising, low-cost, and environmentally friendly alternative to alum for detergent wastewater treatment.

Abstract

Penatalaksaan inflamasi di Indonesia saat ini menggunakan obat golongan AINS (Antiinflamasi Non Steroid) maupun AIS (Antiinflamasi Steroid). Mekanisme kerja obat tersebut berhubungan dengan biosintesis prostaglandin, yaitu menghambat kerja enzim siklooksigense yang menyebabkan penurunan sintesa prostaglandin. Akan tetapi, penggunaan obat-obatan tersebut menunjukkan berbagai efek samping seperti tukak lambung, dispepsia, cushing, osteoporosis dan immunosuppresif. Penelitian ini merupakan penelitian eksperimental secara in silico pada daun papaya (Carica papaya L.) yang mengandung flavonoid diduga sebagai senyawa antiinflamasi. Tujuan penelitian ini untuk mengetahui interaksi senyawa flavonoid dengan COX-2 secara in silico. Hasil penelitian menunjukkan senyawa flavonoid diduga sebagai antiinflamasi dengan menghasilkan nilai ∆G antara COX-2 dengan flavonoid sebesar -44,92 kcal/mol. Interaksi yang terjadi antara reseptor COX-2 dengan flavonoid, yaitu terjadinya ikatan hidrogen antara atom O dari flavonoid dengan beberapa residu asam amino dari COX-2, yaitu Aspargarin 39, Lisin 469 dan Sistein 47.

Abstract

Zat besi merupakan salah satu mikromineral yang penting dalam tubuh karena peranan dalam pembentukan sel darah merah. Zat besi dapat ditemukan pada sayuran hijau, salah satunya daun singkong (Manihot esculenta Crantz). Perebusan dilakukan supaya daun singkong menjadi empuk dan lunak. Namun, proses perebusan dengan penambahan zat aditif masakan yang umumnya dilakukan oleh masyarakat dapat memberikan perubahan terhadap ketersediaan zat gizi yang terkandung didalamnya termasuk zat besi. Tujuan penelitian ini yaitu untuk mengetahui pengaruh penambahan zat aditif pada perebusan pada daun singkong terhadap kadar besi (Fe) menggunakan spektrofotometri serapan atom (SSA). Sampel yang digunakan adalah daun singkong yang direbus dengan air biasa, air garam serta air garam ditambah baking soda. Pengujian dilakukan dengan menggunakan Spektrofotometri serapan atom (SSA) pada panjang gelombang 248,3 nm. Kadar Fe dalam sampel yang diteliti yaitu pada sampel yang direbus air sebesar 2,611 mg/100 gr, sampel yang direbus air garam sebesar 2,090 mg/100 gr, dan sampel direbus air garam dan baking soda sebesar 1,651 mg/100 gr. Dari penelitian ini diketahui bahwa kadar Fe tertinggi terdapat pada sampel yang direbus air dan penambahan zat aditif berpengaruh terhadap kandungan zat Besi.

Abstract

The increasing consumption of biodiesel has led to the continued development of biodiesel production using oils that do not compete with food, for example castor oil. This study aims to synthesize and characterize castor oil methyl ester (COME) as biodiesel. The FFA of castor oil is 0.66%, so that a transesterification reaction with methanol using a KOH catalyst can be carried out. The reaction was characterized by Thin Layer Chromatography (TLC) and Gas Chromatography-Mass Spectrometry (GCMS). The highest content of COME is methyl ricinoleate at 65.481%. followed by FFA at 0.4%, a cloud point of -9°C, a pour point of -18°C, and a density at 40°C of 887.2 kg/m3 which is in accordance with SNI. Thus, COME has the potential as a biodiesel candidate.
