Abstract

Tomat termasuk komoditas tanaman yang banyak dijumpai di Indonesia, namun memiliki nilai ekonomiyang rendah dan mudah rusak. Salah satu usaha yang dapat dilakukan untuk mengatasi hal tersebut adalah denganmengolah tomat menjadi berbagai produk olahan salah satunya adalah pembuatan bubuk tomat. Pembuatan bubuksuatu bahan dapat dilakukan dengan metode pengeringan pembusaan. Penelitian bertujuan untuk mengetahuipengaruh penambahan maltodekstrin sebagai bahan pengisi terhadap karakteristik fisikokimia bubuk tomat yangdihasilkan. Metode yang digunakan dalam penelitian ini adalah eksperimental laboratorium dengan analisisdeskriptif. Perlakuan yang dicoba adalah penambahan maltodekstrin (10%, 15% dan 20% b/b), dengan tiga kaliulangan. Parameter yang diamati meliputi: rendemen, warna, laju pengeringan, dan karakteristik fisikokimia bubuktomat yang meliputi warna, kadar air, kadar abu, kelarutan, indeks penyerapan air, bulk density, foam density,kadar vitamin C, dan higroskopisitas. Hasil penelitian menunjukkan rata-rata kadar air awal campuran jus dan pulptomat hasil proses mixing adalah 82,68% (bb) hingga 94,9% (bb). Nilai kadar air bubuk tomat berkisar antara5,86% (bb) hingga 15,28% (bb). Pada penelitian ini hasil terbaik terdapat pada bubuk tomat dengan perlakuanpenambahan maltodekstrin 20% dengan hasil rendemen 15,29%; kadar air 5,86%; kadar abu 6,24%; foam density0,57 g/cm3; bulk density 0,77 g/cm3; kelarutan 95,23%; indeks penyerapan air 12,96%; tingkat higroskopisitas11,36%; kadar vitamin C 75,49 mg/100g. Karakteristik warna bubuk tomat pada perlakuan penambahanmaltodekstrin maupun kontrol menghasilkan warna kromatis merah.Kata kunci: bubuk tomat, maltodekstrin, pengeringan pembusaan, tomatABSTRACTTomato is one of plant commodities that easy to find in Indonesia, but it is easily damaged and has a loweconomic price.

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

Red ginger is a spice plant that has high economic and social value. One of the uses of red ginger is to process it into a product, namely essential oil. This study aims to determine the optimization of the extraction process conditions on solvent volume, time, and extraction power that can produce optimum yield and residual content of red ginger essential oil solvent. The extraction was carried out with the help of microwaves. The research method is experimental design and optimization process with Response Surface Methodology (RSM) type Box-Behnken Design (BBD). The results showed that the optimum yield was at 700 mL solvent volume, 1 min extraction time, and 10% power (69.9 watts) with the equation Y = 0.2076 + 0.0262A – 0.0300B – 0.0013C and the concentration conditions the optimum remaining solvent with the equation Y = 4.98 – 1.0000A + 4.56B + 5.44C. The optimal yield of red ginger essential oil was 0.205%, with a residual solvent content of 3.8%, specific gravity 0.885, acid number 1.399, refractive index 1.485. The results of the optimum residual solvent content of -6.023%. Based on the results obtained, the yield value with the help of microwaves is higher than that without the help of microwaves. Keywords: Essential oil, Microwave, Residual solvent content, Response surface methodology (RSM), Yield.

Abstract

Pepper is one of the agricultural commodities that Indonesia widely exports. Pepper can be processed into various products, including essential oils. Pepper essential oil can be extracted using several methods, including the microwave. This method can speed up the essential oil extraction process. Optimization was carried out using the Box-Behnken design using the three independent parameters: solution ratio, time, and microwave power. The upper and lower limits used for the independent variables are solvent amount of 1,350 mL and 750 mL, time of 90 minutes and 60 minutes, and microwave power of 440 watts and 136 watts. The optimal data generated is treatment with a solvent amount of 1,050 mL, 90 minutes, and 440 watts of power, resulting in validation data of 99.046%. The optimal essential oil treatment gives a specific gravity of 0.8281, a refractive index of 1.4824, solubility in ethanol 1:2, acid number 0.739 mg KOH/g, ester number 19.599 mg KOH/g, and a hue value of 186,38 (green). Oil with optimum treatment also has an IC50 antioxidant activity of 32,919.9 ppm. Keywords: Antioxidant; Extraction; Microwave; Pepper; RSM.

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

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.
