Abstract

Commercial biodiesel of oil palm is controversial as the palm oil is classified as food oil and palm plantation utilizesfertile land. One potential type of vegetable oil as biodiesel raw material is kemiri sunan (Reutealis trisperma(Blanco) Airy Shaw) oil. This research aimed to prepare a heterogeneous solid catalyst in the form of an impregnatedSiO2by CaO catalyst (CaO/SiO2), to study the effect of the esterification stage on free fatty acid (FFA) content ofoil, and to test the activity of the CaO/SiO2catalyst during the trans-esterification stage for biodiesel formation. CaO/SiO2catalysts were prepared by sol-gel method made from natural materials (egg shells and rice husk). The FFAcontent of kemiri sunan oil was determined through various esterification stages namely 1; 1.5; and 2 hours in thepresence of H2SO4catalyst. While the trans-esterification stage was carried out under reaction temperature of 60°C,oil to methanol ratio of 1:9, reaction time of 2 hours and CaO/SiO2catalyst content of 3%. The results showed thatthe esterification stage for 1; 1.5; and 2 hours reduced the FFA content from 12.5% (without esterification) to 0.65%;0.58%; and 0.54% respectivaly. Biodiesel made from kemiri sunan oil which was synthesized with the addition ofCaO/SiO2catalyst at optimal conditions of trans-esterification stage fulfilled SNI 7182-2015: Biodiesel based ondensity, viscocity, moisture content, iodine number, and cetane number.

Abstract

Lemon processing generates a substantial amount of peel waste, accounting for approximately 40-50% of the total fruit weight. The lemon peel, particularly the flavedo layer, contains essential oil compounds with the potential to be developed into value-added products through distillation. This study evaluates the influence of distillation duration and temperature parameters on the yield and physicochemical quality of essential oil derived from lemon peel waste. The experiment employed a Factorial Completely Randomized Design (CRD) with two factors: distillation time (P = 4, 5, 6, 7, and 8 hours) and distillation temperature (T = 83, 90, 100, 110, and 117°C). The observed parameters included oil yield, specific gravity, refractive index, acid value, and solubility in 70% alcohol. Data were processed using Analysis of Variance (ANOVA) followed by Duncan's Multiple Range Test (DMRT) at a 95% confidence level. The findings indicate that distillation time significantly affects the essential oil yield, whereas temperature variations within the tested range do not show a significant impact. The highest yield of 0.84% was achieved at a distillation time of 8 hours at 100°C. The resulting essential oil exhibited a specific gravity of 0.851 g/mL, a refractive index of 1.473, an acid value of 5.60 mg KOH/g, and a 1:10 solubility in 70% alcohol, all of which meet quality standards. These results demonstrate that optimizing distillation conditions can enhance yield while maintaining the quality of lemon peel essential oil.

Abstract

Pala (Myristica fragrans) merupakan salah satu komoditas perkebunan unggulan Indonesia dengan nilai ekspor yang cukup tinggi dan prospek pasar yang terus meningkat. Biji pala banyak dimanfaatkan pada berbagai bidang, mulai dari industri pangan sebagai bahan penyedap dan flavoring, industri farmasi sebagai komponen obat tradisional, hingga industri kosmetik. Meskipun demikian, dalam beberapa tahun terakhir sejumlah negara tujuan ekspor menolak pengiriman pala Indonesia karena kadar aflatoksin yang terdeteksi melebihi ambang batas maksimum yang diizinkan. Aflatoksin umumnya terbentuk akibat kontaminasi jamur selama proses panen maupun pascapanen, terutama ketika kondisi kadar air tidak terkendali. Proses pengeringan yang kurang optimal dan penyimpanan yang tidak sesuai seringkali meningkatkan kadar air biji pala sehingga menciptakan lingkungan yang mendukung pertumbuhan kapang penghasil aflatoksin. Oleh karena itu, penentuan kadar air kesetimbangan dan kondisi penyimpanan yang tepat melalui pendekatan sorpsi isotermis sangat penting untuk meminimalkan risiko kontaminasi. Penelitian bertujuan mengidentifikasi kondisi penyimpanan optimal yang mampu mencegah pertumbuhan mikroorganisme penghasil aflatoksin pada biji pala. Metode yang digunakan adalah eksperimen dengan menentukan Kurva Sorpsi Isotermis menggunakan larutan garam jenuh NaOH, CH3COOK, MgCl2, Kl, NaCl, KCl, BaCl2, pada berbagai tingkat aktivitas air. Data hasil pengukuran kemudian dianalisis menggunakan model sorpsi Halsey, Henderson, Caurie, Oswin, Chen-Clayton, GAB, dengan mengevaluasi akurasi melalui perhitungan nilai Mean Relative Deviation (MRD). Hasil penelitian menunjukkan bahwa model Oswin  y=0.0851x+0.0333 menghasilkan nilai MRD terendah yaitu 1,6497, sehingga model yang paling sesuai dalam memprediksi kadar air kesetimbangan bubuk pala. Dengan demikian, model Oswin dapat dijadikan acuan dalam merancang strategi pengeringan dan penyimpanan pala untuk menjaga mutu serta meningkatkan ekspor

Abstract

This study aims to optimize the biocomposites of sago pith waste (SPW) for sustainable packaging applications. The biocomposite was prepared using the biodegradable polymer polybutylene adipate-co-terephthalate (PBAT) as a matrix and methylendifenyl diisocyanate (MDI) as a chain extender. RSM-CCD was used to assess the impact of the incorporation of SPW (5-20% p/p) and MDI (1–5%) into the PBAT matrix on the tensile strength and elongation of biocomposites by melt mixing. The optimal formula shown by RSM was 5% SPW and 5% MDI, which resulted in a 5.14 MPa tensile strength and 8.14% elongation. The barrier properties of all treatments, including moisture content, contact angle, and water absorption, were checked. The optimal formula showed good barrier properties compared to other treatments: water content of 3.12%, contact angle of 42.84°, and water absorption of 0.82%. Other characterizations of SEM, FTIR, DSC, TGA, and biodegradability tests showed an increase in SPW-PBAT compatibility due to the use of MDI. MDI as a chain extender had a positive impact on the material's strength, and the addition of SPW accelerated the degradation process, thus improving biodegradability. Keywords: Biocomposite, Chain extender, Melt-mixing, Response Surface Methodology, Sago pith waste.

Abstract

Carrot pulp is a by-product of juice production with a source of pectin and carotene precursors of vitamin A. One way to use carrot pulp is through a drying process, such as convection drying, to produce carrot pulp flour. The purpose of this study was to determine the optimal conditions for drying carrot pulp using a food dehydrator, to determine the characteristics of carrot pulp powder under optimal conditions, and to determine the potential of carrot pulp powder in preparing peel off gel masks. The parameters in this study were moisture content, ash content, and drying yield. In addition, the parameters observed in the optimum carrot pulp flour were color and antioxidant activity. The dryer used was a food dehydrator operating at a temperature range of 45°C to 65°C for a duration of 20 to 26 hours. This research method was an experimental method with optimization using the Response Surface Methodology (RSM) type Central Composite Design (CCD) in the Design Expert 13 application. RSM determined the optimal drying process condition to be 65°C for 26 hours. This condition resulted in a product with a moisture content of 3.033%, an ash content of 5.326% and a drying yield of 11.062%. Carrot pulp flour produced under optimal drying conditions, when formulated into a peel off gel mask preparation, exhibited a drying time of 15-21 minutes.

Abstract

Red ginger contains volatile components that are essential oils. Essential oils can be obtained through the distillation method. Hydrodistillation is a method of distillation that involves providing direct contact between the materials and water at a high temperature, which is influenced by several factors, including time and the solvent feed ratio (SF ratio). This study aimed to determine the best conditions for high yields and essential oil quality using SNI No. 06-1312-1998 as a reference. The research method used was experimental research, and optimization was carried out using Response Surface Methodology (RSM) with CCD design. The treatments for distillation were time (2 hours, 4 hours, and 6 hours) and solvent feed (SF) ratio (8:1, 10:1, and 12:1). The parameters observed were yield, residual solvent content, specific gravity, refractive index, and acid number. The results showed that the time and SF ratio variables had no significant effect on the yield but had a significant effect on the residual solvent content. The optimization process resulted in a time of 6 hours and a solvent volume of 720 ml (ratio 1:12), yielding 0.14 with a residual solvent content of 3,557%. The characteristics of the essential oils produced were 0.8794 for the specific gravity, 1.473 for the refractive index, and 2.13  for the acid number. Red ginger essential oil met the requirements of SNI ginger oil on the parameters of specific gravity and refractive index.

Abstract

Guaiene is a derivative compound produced as a byproduct in the production of patchouli alcohol from patchouli oil (Pogostemon cablin Benth.). This study aims to evaluate the antifungal activity of δ-guaiene extracted from patchouli oil originating from Subang against four types of skin pathogenic fungi: Aspergillus niger, Candida albicans, Microsporum gypseum, and Trichophyton mentagrophytes. The method used was a laboratory experiment, with the main parameters observed including Inhibition Zone Diameter (IZD), Minimum Inhibitory Concentration (MIC), and Minimum Fungicidal Concentration (MFC). The results showed that δ-guaiene inhibited the growth of C. albicans at a concentration of 40%, with an IZD of 0.15 mm. Against A. niger, the compound demonstrated an inhibition zone of 1.4 mm at a 20% concentration and had an MFC of 20%. For T. mentagrophytes, an IZD of 0.4 mm was observed, with both MIC and MFC at 20%. Activity against gypseum showed an IZD of 0.25 mm, with MIC and MFC also at 20%. These findings suggest that δ-guaiene from patchouli oil has potential as a candidate antifungal agent derived from local resources, supporting the development of natural bioactive compounds and sustainability.

Abstract. Amien S, Maulana H, Ruswandi D, Nurjanah S. 2021. Genetic gain and relationship of yield and yield attributes of mutant and cross-bred stevia (Stevia rebaudiana) genotypes. Biodiversitas 22: 3119-3126. Plant breeding programs involved many traits and genetic parameters in the selection process. The information on genetic parameters on yield and other related traits provided an overview for breeders and farmers in selecting new superior genotypes. The purpose of this study was to estimate genetic parameters including heritability and genetic gains in yield and other traits, to determine the relationship between various traits, and to select superior stevia (Stevia rebaudiana Bertoni) genotypes for each trait. Field experiments were carried out in two planting environments, namely, the highlands and the medium plains employing a randomized completed block design and each genotype was three replicates. The results showed that the yield had high heritability and genetic gains  ??in mutant populations, whereas cross-bred populations had moderate heritability and low genetic gains. Stem weight (SW) and number of leaves (NoL) traits were identified as having high heritability and genetic gains in both populations. The GT biplot measurement showed that the yield was identified to have a significant and positive correlation with SW (p<0.05). H4 was correlated with Number of branches (NoB), Yield, SW, and chlorophyll content (Chl) traits in the cross-bred populations. H9 excelled on and was correlated with NoL and plant height (PH). M11 was identified to be highly correlated with NoL, PH, NoB, and Chl traits in the mutant populations, while M15 excelled on and was correlated with yield and SW. The results of this study revealed that there was a potential for improvement in the traits tested of stevia through cross-bred and mutant populations in different environmental conditions. The selected genotypes can be developed in a suitable environment and used for further stevia plant breeding programs.
