Abstract

Pengembangan UMKM berbasis pangan lokal merupakan strategi penting dalam mendorong pertumbuhan ekonomi pedesaan. Salah satu contohnya adalah usaha keripik ubi Oemah Pawon Mbok Wo di Dusun Mardiasri, Desa Jururejo, Kecamatan Ngawi, yang masih menghadapi kendala teknis dan finansial. Penelitian ini dilakukan melalui observasi lapangan, wawancara, serta analisis biaya dan penerimaan dengan menggunakan instrumen pembukuan arus kas dan perhitungan indikator finansial. Hasil analisis teknis menunjukkan usaha dinyatakan layak karena didukung lokasi yang dekat dengan sentra ubi, ketersediaan bahan baku yang stabil, penggunaan teknologi vacuum frying yang meningkatkan kualitas produk, serta distribusi yang cukup lancar. Sementara itu, hasil analisis finansial secara kuantitatif memperlihatkan bahwa sebelum ekspansi investasi awal sebesar Rp 1.565.000 dengan biaya operasional Rp 65.432.500 menghasilkan NPV Rp 216.071.159, IRR 72,27%, dan Payback Period 9,7 bulan. Setelah ekspansi, investasi awal meningkat menjadi Rp 32.515.000 dengan biaya operasional Rp 125.912.500, tetapi nilai NPV naik menjadi Rp 317.898.191, IRR tercatat 67,07%, dan Payback Period 11,6 bulan. Perbandingan ini menunjukkan bahwa meskipun efisiensi relatif menurun, keuntungan absolut serta kapasitas produksi meningkat secara signifikan. Analisis sensitivitas juga menegaskan bahwa meskipun perubahan harga bahan baku atau harga jual berpotensi memengaruhi margin dan periode pengembalian, kapasitas produksi yang lebih besar setelah ekspansi membuat usaha lebih adaptif. Oleh karena itu, penambahan mesin vacuum frying dapat dipandang sebagai strategi pengembangan yang tepat untuk memperkuat keberlanjutan dan daya saing UMKM keripik ubi di pasar yang lebih luas.

Abstract

The gonggong snail shell contains high calcium, reaching 67.70%, which potential to be used as a source of natural hydroxyapatite. Hydroxyapatite can be used as a biomaterial for bone substitutes because it is able to integrate with bone tissue without causing toxic effects or inflammation. The purpose of this study was to analyze the effect of temperature and precipitation synthesis time on the characteristics of hydroxyapatite produced from the gonggong snail shell for bone substitute biomaterials. The results showed that precipitation at 900 °C for 4 h is the best solution for synthesizing hydroxyapatite with a Ca/P ratio of 2.76, closely approximating the stoichiometric value of HAp. SEM revealed that the synthesized HAp exhibited a spherical morphology with a tendency to form granular aggregates. FTIR confirmed the presence of characteristic PO43− and OH− functional groups. XRD analysis indicated that primary phase of the synthesized material was HAp, consistent with JCPDS data. The optimal immersion time and temperature for fabricating at 900 °C for 4 h in HAp:alginate ratio (w/w) of 2.5:7.5 (HAPT2C) based on their mechanical properties. But HAp:alginate ratio (w/w) of 5:5 (HAPT2A) demonstrated higher water absorption compared to HAPT2C in the water uptake test. HAp from gonggong snail shell are promising biomaterial candidates for bone substitution applications, warranting further investigation through in vitro and in vivo biocompatibility studies.

Abstract

Tobacco stems (Nicotiana tabacum L.) are abundant agricultural byproducts that are rich in bioactive compounds. Their potential remains underexploited due to limitations in current processing and extraction technologies. This study aimed to identify superior tobacco varieties and optimize Ultrasound-Assisted Extraction (UAE) conditions for total phenolic content (TPC), Total flavonoid content (TFC), and antioxidant activity from tobacco stems. The research was conducted in two sequential stages: (1) Preliminary study for screening of TPC  and antioxidant activity of varieties Paiton 4 and Gagang Rejeb Sidi; (2) Experimental set-up using a Randomized Complete Block (RCB) Design was employed, on the selected superior variety, arranged in a factorial with three replications, factors of temperature (i.e., 40, 50, and 60 °C) and  extraction time (i.e., 30, 45, and 60 minutes). Preliminary results showed the superiority of Paiton 4, with TPC of 568.09 mg GAE/100 g and the highest antioxidant activity (IC50 of 1286.86 ppm). These results revealed that the best selected treatment achieved at a temperature of 40 °C for 60 minutes, producing the highest TPC (195.64 mg GAE/100 g) and the strongest antioxidant activity (141.87 µg AAE/g). This proved the effectiveness of low-temperature UAE in protecting heat-sensitive compounds, although the highest Total Flavonoid Content was obtained at 45 minutes.

Abstract

Tobacco stems (Nicotiana tabacum), often discarded as waste, have significant potential as a source of secondary metabolites, including bio-oil. This study examines the effect of elevation on the chemical composition of White Burley tobacco stems from lowland, midland, and highland regions in Lumajang District using Fourier Transform Infrared Spectroscopy (FTIR). The FTIR results revealed distinct variations in functional groups: the lowland sample showed strong O–H, C–H aliphatic, C=O, and C–O peaks, indicating the presence of oxygenated compounds typical of bio-oil. The midland sample exhibited O–H, C–H aliphatic, and C–O–C bands, suggesting volatile organic and polar compounds. The highland sample revealed O–H, C–H, C=O, and C–O peaks, indicating both polar and non-polar compounds. Physicochemical analysis of aqueous extracts prepared from the same lowland, midland, and highland stem samples showed that the pH values were similar across samples (8.35–8.59), with the lowland sample having the lowest density (1.032 g/mL). These attributes suggest the lowland sample is most favorable for bio-oil production due to its closer pH to diesel oil and lower density. The findings indicate that elevation influences tobacco stem metabolites and physical properties, with lowland stems showing the greatest potential for high-quality bio-oil production.

Abstract

Nicotine is the primary alkaloid in tobacco (Nicotiana tabacum L.), playing a significant role in determining tobacco quality. The Madura variety (Prancak 95) is highly adaptable to dryland conditions, making it suitable for studying the dynamics and rate of nicotine formation at different growth stages and leaf positions. This study aimed to measure nicotine content in Madura tobacco leaves based on plant age and leaf position and to determine its formation rate between growth phases. The experiment employed a randomized block design (RBD) with a factorial pattern, comprising plant age (i.e., 25, 40, 55, 70, and 85 days after transplanting/DAT) and leaf position (i.e., lower, middle, and upper) in three replications. Nicotine content was analyzed using the acidimetric titration method (SNI 01-7134-2006), and the formation rate was calculated as the difference in nicotine content between growth stages divided by the time interval. Results showed that nicotine content increased from 1.24% (25 DAT) to 2.72% (85 DAT). Average nicotine contents were 2.43% (upper), 1.86% (middle), and 1.64% (lower leaves). At 85 DAT, the upper leaves contained about 43% more nicotine than that of the lower leaves. The highest rate of nicotine formation occurred at 70–85 DAT.

Abstract

Functional beverages are increasingly popular due to their health benefits. Spiced coffee has the potential to be developed as a functional drink because of its caffeine and antioxidant content. This study aimed to determine the optimum formulation of Arabica coffee with the addition of spices and to evaluate consumer acceptability. The research design employed the Simplex Lattice Design (SLD) method with coffee concentrations of 94–98% and spice concentrations of 2–6%. The responses observed included antioxidant activity, total phenolic content, and caffeine levels. Data were analyzed using Design Expert 13, while hedonic testing was conducted with Minitab 21 involving 30 panelists. The results indicated that the optimum formulation consisted of 94% coffee and 6% spices, with predicted values of IC50 at 91.428 ppm, total phenolics at 41.105 mg GAE/g, caffeine at 8.569 mg/g, and desirability at 0.865. Sensory evaluation using the 1-sample Wilcoxon test showed that panelists rated the product in the “like” category with a median score of 6, characterized by a dark brown color, dominant spice aroma, and slightly bitter taste.

Abstract

Coffee consumption has been associated with metabolic health and obesity risk, potentially through bioactive compounds that influence energy metabolism. Genetic variation may partly explain interindividual differences in these effects, yet the population-specific relevance of such variants remains unclear. However, the population-specific relevance of these genetic variants remains insufficiently explored. OBJECTIVES: This systematic review synthesizes genetic variants associated with coffee consumption and obesity susceptibility across ethnically diverse populations and validates their relevance in global populations using public genomic databases. METHODS: A comprehensive literature search was conducted in PubMed, Scopus, Web of Science, and Google Scholar to identify genome-wide association studies and candidate gene studies examining genetic variants related to coffee consumption, caffeine metabolism, and obesity-related traits. Identified variants were cross-referenced with dbSNP and the GWAS Catalog to assess allele frequency distributions and genomic support. Study quality was evaluated using the National Institutes of Health assessment tools for observational studies. RESULTS: The review identified genetic variants involved in caffeine metabolism (POR, ALDH2, GCKR), neuroregulation and appetite control (BDNF), taste perception (TAS2R38, CA6), adipokine regulation (KNG1), dietary fat response (APOA2), and obesity susceptibility (MC4R, ARL15).   Public genomic database analyses suggest that several variants are consistently observed across global populations, supporting their potential generalizability. CONCLUSION: This review highlights the broad population-genetic predispositions underlying the relationship between coffee consumption and obesity risk and supports the need for future research that integrates multi-omics approaches with in vivo and in vitro models to elucidate the biological mechanisms of coffee-related genetic variation.
