Pati alami memiliki aplikasi terbatas karena tidak selalu memiliki sifat yang diinginkan untuk beberapa jenis pengolahan. Oleh karena itu diperlukan modifikasi untuk meningkatkan penggunaan dari pati tersebut, salah satunya dengan melakukan modifikasi pada struktur pati. Penelitian ini bertujuan untuk menghasilkan pati termodifikasi yaitu pati ikat silang fosfat. Pati ikat silang fosfat disintesisÂ denganÂ mereaksikan pati sukun dengan natrium trimetafosfatÂ dan dilakukan variasiÂ berat natrium trimetafosfat (1%, 2%, 3%) dan waktu reaksi (30, 60 dan 90 menit). Dari hasil uji yang dilakukan dengan menggunakan spektroskopi IR maka terbentuknya pati fosfat didukung dengan munculnya vibrasi P-O-C pada daerah bilangan gelombang 1050-995 cm-1 dan daerah 1643 cm-1. Pengaruh penambahan konsentrasi trinatrium trimetafosfat dapat meningkatkan nilai derajat substitusi dan menurunkan swelling power. Derajat subtitusi diperoleh berkisar antara 0,2343-0,3003, dimana derajat substitusi yang paling tinggi diperoleh pada penambahan berat natrium trimetafosfat 3% dan waktu reaksi 60 menit yaitu 0,3003.

Realizing abundant availability of local bovine bone wastes in Aceh Province, Indonesia, this study is subjected to take competitive advantages from the local bovine bone waste for preparing an inorganic catalyst preparation. In detail, calcined Aceh bovine bones were successfully intercalated lithium through an impregnation method resulting in the inorganic base catalyst, which showed promising activity in the transesterification of castor oil. Prior to the experiment, the Aceh bovine bone waste was calcined at 900 oC in the air atmosphere for 4 hours, led to forming crystalline phases of hydroxyapatite [Ca5(PO4)3(OH)] and calcium oxide [CaO]. Also, the chemical modification of calcined bovine bone with lithium precursor has enhanced the physicochemical properties of the inorganic base catalyst. Finally, the intercalated Aceh bovine bone has shown a feasible activity in transesterification of castor oil into biodiesel, which yielding methyl ricinoleate as the main product.

Edible film can be used to package food well and improve the condition of the food, but damage to food ingredients can also occur due to bacteria, so chitosan-nisin is added as an antibacterial agent. In this research, Edible Film was made by adding 1,2,3,4 g of nisin to a 1% (w/v) chitosan solution to obtain four antibacterial agent solutions, namely 1.0% chitosan and chitosan-nisin: 0.1; 0.2; 0.3 and 0.4% (w/v), then mixed with distilled water, phosphate starch of yellow ivory coconut shoots, and sorbitol, then stirred with a magnetic stirrer, molded and dried in an oven and then tested for the antibacterial properties of the Edible film. The research results showed that Edible Film containing chitosan-nisin solution was the most potent antibacterial in inhibiting 1% chitosan solution with 0.4% nisin with the inhibition zone for each bacterium ranging between 29.9 mm, 30.6 mm. and 28.2 mm. Antibacterial activity increased with increasing concentration of chitosan-nisin solution.

Breadfruit (Artocarpus altilis) is a significant starch source, comprising up to 70.25% of its composition, and holds extensive industrial applications. However, the physicochemical properties of natural starch pose several challenges to its direct use as an industrial raw material. These challenges include high viscosity, substantial swelling power, low solubility, significant retrogradation, limited digestibility, and poor thermal stability. To address these issues, modification of the starch particle size to the nanometer scale is proposed, which is anticipated to enhance both functional and physicochemical properties. This study employs a top-down approach through 2.2 N HCl acid hydrolysis at 38°C for 24 hours. This method offers simplicity, efficiency for scale-up in industrial applications, and relatively higher stability than alternative approaches. Particle size analysis using Particle Size Analysis (PSA) revealed an average particle size of 215 nm. Fourier Transform Infrared (FT-IR) spectroscopy showed characteristic bands similar to natural starch, with slight variations in peak intensity, indicating successful acid hydrolysis and structural disruption of the molecular order. Morphological analysis revealed minimal changes in the granules' surface structure, with clumping observed due to acid hydrolysis. The resultant starch nanoparticles exhibited decreased viscosity and swelling while solubility was enhanced. Therefore, nanoparticle starch holds promising applications in food and non-food industries.

Waste cooking oil (WCO) is a group of oils or fats that have been used for cooking or frying repeatedly and are no longer suitable for use. Repeated heating of cooking oil will cause the formation of trans fatty acids that trigger coronary heart disease (CHD). This study aims to synthesize esters as biolubricant candidates from WCO. WCO was purified using 0.05% (v/v) of H3PO4 and 2% (w/v) of bleaching earth, then saponified with ethanolic NaOH and hydrolyzed with 25% H₂SO₄. The fatty acids obtained were then esterified with pentaerythritol using a dean-stark distillation apparatus with 2% H2SO4 catalyst and toluene solvent at a temperature of 170-180°C for 6 hours. The results of the acid number analysis showed an ester conversion of 83.08%. Furthermore, the FT-IR spectra showed the presence of C=O (1730 cm⁻¹) and C–O–C (1178 cm⁻¹) groups, indicating the formation of esters. These results indicate that esters from used cooking oil have the potential to be environmentally friendly biolubricants.

Natural starch-based materials are promising for drug delivery due to their biodegradability, abundance, and biocompatibility. This study isolated starch from breadfruit (Artocarpus altilis) and converted into nanoparticles via acid hydrolysis using HCl 2.2 N under shaking incubation at 38°C for 24 hours. The process yielded nanoparticles with a recovery efficiency of 67% and an average particle size of 347.76 nm—within the optimal range for passive tumor targeting via the enhanced permeability and retention (EPR) effect. Compared to native starch, the nanoparticles exhibited enhanced solubility and reduced viscosity, indicating improved aqueous dispersion. FTIR spectroscopy confirmed the retention of major functional groups, while SEM analysis showed distinct changes in surface morphology indicative of granule disintegration. To evaluate pharmaceutical applicability, doxorubicin hydrochloride (DOX) was employed as a model drug. The breadfruit starch nanoparticles achieved a high drug loading efficiency of 78.3%. These results demonstrate the potential of breadfruit starch nanoparticles as a sustainable, low-cost drug delivery platform and highlight the value of underutilized tropical starches in nanomedicine.

Schiff bases were successfully synthesized via a condensation reaction between dialdehyde starch (DAS), derived from breadfruit (Artocarpus altilis) starch, and aniline. DAS was prepared through oxidative cleavage of the vicinal diol groups in native starch using sodium periodate. The formation of DAS was confirmed qualitatively by the appearance of a brick-red precipitate upon addition of Fehlings reagent and a marked increase in its water solubility. Fourier Transform Infrared (FT-IR) spectroscopy revealed a strong absorption band at 1635.64 cm, corresponding to the aldehyde C=O stretching vibration, supporting the successful oxidation. The oxidized starch showed a high degree of oxidation (80.9%) and a carbonyl content of 10.36%. Condensation between the aldehyde groups of DAS and the amino group of aniline resulted in the formation of a Schiff base. FT-IR analysis of the resulting compound revealed absorption bands at 1635.64 cm and 1604.77 cm, indicating the formation of imine (-C=N-) bonds, while a peak at 871.82 cm confirmed the presence of aromatic ring structures. The antibacterial activity of the synthesized Schiff base was evaluated using the disk diffusion method, showing strong inhibitory effects against Escherichia coli and Staphylococcus aureus. These findings showed that starch-based Schiff bases represent a promising class of biodegradable antibacterial agents with potential applications in biomedicine and biomaterials.
