Abstract

– We reported our study the electronic structure of graphene in bulk structure and graphene quantum dot (GQD) by density functional theory (DFT) by using in quantum espresso (QE) package. In order simulate the realistic shape of GQD, we set vacuum layer to avoid interaction between quantum dot in the periodic structure in crystal. We examined various shape of quantum dot namely triangular, Hexagon, parallelogram. The band gap is tunable by its shape which open wide application of GQD. We showed that we can tuning the electronic structure of graphene by tuning its structure. In bulk structure, graphene is zero-gap semiconductor. On the other hand, the results on GQD showed the discrete energy level and different shapes of GQD have different energy level and band gap.

Abstract

This study aims to determine the effect of edible coating on the shelf life of passion fruit (Passiflora edulis). Edible coating is modified using durian seed starch. This study used a Completely Randomized Design with three treatments and three replications. The treatments used were the addition of starch and glycerol, respectively 4% and 4%, 6% and 2%, 2% and 6%, 7% and 1%, 8% without the addition of glycerol. The parameters observed were mass loss, total dissolved solids. The results showed that the edible coating with a concentration of 4% durian seed starch and 4% glycerol was the best because it was able to extend the shelf life of passion fruit. In addition, it is able to inhibit the increase in the value of weight loss and total dissolved solids.

Kualitas kimia yang diukur adalah dissolved oxygen (DO), pH, dan salinitas. Sedangkan kualitas mikrobiologi yang diukur adalah kandungan bakteri Escherchia coli. Sampel air diambil dari air sumur gali di dusun Cabbia (AS-1) dan dusun To’balo (AS-2 dan AS-3), Kemudian dianalisis di Laboratorium Dinas Lingkungan Hidup Kabupaten Luwu. Jenis penelitian ini yaitu deskriptif kualitatif dengan mengunakan variabel tunggal yaitu memaparkan variabel yang akan diteliti tanpa melakukan analisa antar variabel dan hasil penelitian ini dalam bentuk deskripif. Hasil penelitian menunjukkan AS-1, AS-2, AS-3 tidak memiliki bau dan rasa, sedangkan analisis warna dihasilkan pada sampel AS-1 (16 TCU), AS-2 (49 TCU), dan AS-3 (24 TCU). Pada analisis kimia berupa DO dihasilkan pada sampel AS-1 sebesar (2,49 mg/L), sampel AS-2 sebesar (1, 81 mg/L), dan sampel AS-3 sebesar ( 1, 97 mg/L), Nilai pH pada sampel AS-1 sebesar (6, 97), AS-2 sebesar ( 6, 93), AS-3 sebesar (7, 06), Salinitas air sampel AS-1 sebesar (0, 2%), AS- 2 sebesar (0, 3%), dan AS-3 sebesar (0,3%). Analisis mikrobiologi pada sampel AS-1 sebanyak (9 MPN/100/mL), AS-2 sebanyak (5 MPN/mL), dan AS-3 sebanyak (17 MPN/100mL). Air sumur gali yang berada di Desa To’balo tersebut tidak layak untuk dikonsumsi secara langsung tanpa pengolahan terlebih dahulu, karena hasil yang telah didapatkan setelah penelitian ada beberapa parameter yang tidak sesuai dengan peraturan yang telah di tentukan.

Abstract

Blumea balsamifera (sembung) is a medicinal plant with well-documented antibacterial, anti-inflammatory, and analgesic properties. However, the systematic identification of its bioactive compounds remains a significant challenge due to the complexity and high dimensionality of LC–MS (Liquid Chromatography–Mass Spectrometry) data. This study aims to develop a robust computational framework for automated compound identification using a hybrid modeling approach.A hybrid model integrating Long Short-Term Memory (LSTM) and Extreme Gradient Boosting (XGBoost) was employed to enhance feature extraction and classification performance. The LSTM component was utilized to capture sequential dependencies in spectral data, while XGBoost performed optimized classification through gradient boosting. This integration enables efficient handling of complex spectral patterns and improves predictive accuracy.The proposed model achieved an accuracy of 91%, demonstrating strong performance in classifying and identifying bioactive compounds. Feature importance analysis identified several key compounds contributing to the model predictions, including Luteolin-7-methyl-ether, Umbelliferone, Blumeatin, Dihydroquercetin-7,4′-dimethylether, Chrysosplenol C, Blumealactone B, and Blumeaene E. These compounds are associated with known pharmacological activities, supporting the therapeutic relevance of B. balsamifera.The proposed hybrid LSTM–XGBoost framework provides an effective and scalable approach for LC–MS-based compound identification. This method reduces analytical complexity, enhances classification reliability, and offers a data-driven strategy for accelerating phytochemical research and bioactive compound validation

Abstract

The catalytic pyrolysis of polypropylene (PP) has attracted considerable attention as a promising approach for converting plastic waste into valuable fuels; however, the development of low-cost and sustainable catalysts remains a major challenge. In this study, the catalytic pyrolysis of polypropylene was conducted to investigate the effect of nickel supported on activated carbon (Ni/AC) derived from sago waste on liquid yield and hydrocarbon selectivity. Pyrolysis experiments were performed at 500 °C using catalyst loadings of 2.5 g, 5 g, and 7.5 g, alongside a non-catalytic run for comparison. The introduction of Ni/AC significantly enhanced liquid production compared to thermal pyrolysis, with the optimum yield achieved at moderate catalyst loading. Gas Chromatography–Mass Spectrometry (GC–MS) analysis confirmed that the liquid fraction was mainly composed of hydrocarbons in the gasoline (C₅–C₁₂) and diesel (C₁₃–C₂₀) ranges. Higher catalyst loading promoted secondary cracking, shifting selectivity toward gaseous products. These findings demonstrate that Ni/AC catalysts from sago waste provide an effective and sustainable approach for converting plastic waste into fuel-like hydrocarbons, underscoring their potential role in plastic waste valorization and sustainable energy development.

Abstract

Rumput laut merupakan komoditas strategis sektor kelautan dan perikanan Indonesia dengan prospek ekonomi yang tinggi, baik untuk konsumsi langsung maupun sebagai bahan baku industri makanan, farmasi, dan kosmetik. Desa Tirowali di Kecamatan Ponrang merupakan salah satu wilayah pesisir yang berfokus pada budidaya Eucheuma cottonii. Hasil observasi dan wawancara dengan Kelompok Tani “Pembudidayaan Ikan Ponrang Katonik” menunjukkan bahwa luas area budidaya mencapai 11 hektar dengan produktivitas rata-rata 1,1 ton/Ha menggunakan metode longline. Permasalahan utama yang dihadapi adalah perubahan kualitas air pada musim hujan, serangan hama, teknik pengeringan pasca panen yang masih tradisional sehingga menurunkan mutu, serta lemahnya akses pasar yang menyebabkan harga jual rendah. Artikel ini membahas pentingnya pemberdayaan petani melalui peningkatan kapasitas teknis, penerapan teknologi tepat guna, perbaikan sistem pasca panen, diversifikasi produk olahan, dan penguatan kelembagaan ekonomi. Hasil pelaksanaan menunjukkan diperoleh Mitra pada saat sebelum dan setelah didampingi terdapat peningkatan hasil produksi budidaya rumput laut maupun dari hasil pemasaran. selain itu, mitra telah mahir menggunakan seluruh teknologi yang ditransfer sehingga mitra tetap dapat menjalankan usahanya berdasarkan pelatihan dari tim pelaksana, serta menjadikan Desa Tirowali sebagai sentra rumput laut yang berdaya saing dan mampu meningkatkan kesejahteraan masyarakat pesisir.
