Abstract

Red palm oil (RPO) is known for its high carotenoid content, particularly β carotene and α-carotene, which provide significant provitamin A activity. However, it is susceptible to oxidation during frying and results in nutrient loss and quality degradation. This study investigates the effects of high temperatures and prolonged heating durations on the chemical and sensory properties of RPO. The experiment involved heating RPO at three different temperatures (140°C, 180°C, and 220°C) for durations ranging from 2 to 10 hours. Chemical analysis included peroxide values, free fatty acids, and changes in functional groups through Fourier Transform Infrared (FTIR) spectroscopy. Sensory evaluations focused on aroma and color alterations due to heating. Results showed that prolonged heating of RPO at high temperatures led to significant increase in peroxide values, and the formation of oxidation products, including aldehydes and ketones, which negatively impacted the sensory qualities. The oil darkened, and a burnt aroma developed, reducing overall sensory appeal. These findings provide new insights into the optimal frying conditions to preserve the nutritional and sensory qualities of RPO, particularly by minimizing heating duration and temperature. Keywords: Nutritional value, Prolonged heating, Red palm oil, Sensory attributes, Thermal oxidation.

Abstract

Facial skin is most often exposed to UV rays and various disorders that need special creams with active ingredients containing antioxidant properties. This study aims to determine the chemical compounds of butterfly pea or telang flower (Clitoria ternatea L.) and determine the antioxidant activity of its cream products. Six treatments consisted of ratio flower extract to honey were performed. The chemical components of telang flower were determined by GCMS method and antioxidant activity test using DPPH method. Results showed that major compound with retention at 23.989; 27.039; and 27.641 min were hexadecanoic acid, oleic acid, and octadecanoic acid with area percentage of 32.70%; 28.92%; and 15.42%, respectively. In addition, there were 5 minor compounds including palmitoyl chloride with retention 28.710 min and area of 7.07%, glycidyl palmitate (retention 18.767 min, area of 5.76%), Heptacosanol (retention 22.818 min, area of 3.01%), Nitroisobutylglycerol (retention 18.059 min, area of 4.50%), and Hydroxymethylfurfural (retention 14.324 min, area of 2.61%). Based on the antioxidant activity test, the highest antioxidant activity results were found in cream formulation 1 (F1) with an IC50 of 3.906 μg/mL, followed by cream formulation 2 (F2) which has antioxidant activity after of 6.532 μg/mL. Keywords: Antioxidant activity, Telang flower, DPPH, GCMS, Honey.

Abstract

The utilization of technology in the agricultural industry is significantly growing recently. This is mostly due to its ability to enhance labor and land productivity, while simultaneously reducing production costs. The objective of this study is to examine the institutional performance and utilization of farm machinery (alsintan) by rice farmers, and to investigate the correlation between institutional performance and alsintan usage on the productivity and income of rice farmers. The study was carried out in two villages in the Central Lampung Regency, namely Rengas Village in Bekri District, and Trimurjo Village in Trimurjo District. Rice farmers in both villages actively utilized alsintan operated under the alsintan service unit (UPJA). The study findings indicate a strong and meaningful correlation between institutional performance and the utilization of alsintan with productivity and income level of tarmers. Alsintan technology directly impacted productivity and revenue with coefficients of 0.63 and 0.60, with confidence levels of 99.9% and 99.7%, respectively. Institutional performance indirectly affected them with a coefficient of 0.30 and a confidence level of 99.99%. The integration of enhancing institutional performance with the optimization of alsintan technology can foster the enhancement of other factors, such as human resource performance, group member involvement, and external environmental support. Keywords: Alsintan, Institutional, Optimization.

Abstract

Berbagai rempah yang ada di Indonsia telah lama digunakan masyarakat Indonesia sebagai minuman yang diyakini mempunyai beragam khasiat kesehatan.  Salah satu konsumen potensial pengguna minuman fungsional berbahan baku rempah adalah anak-anak usia Taman Kanak-Kanak (TK) karena minuman fungsional rempah dapat menunjang kesehatan pada masa pertumbuhan usia dini.  Berdasarkan hal ini maka Tim Pengabdian pada Masyarakat Jurusan Teknologi Hasil Pertanian, Fakultas Pertanian, Universitas Lampung (Tim PPM THP FP Unila) melakukan pengenalan dan pembiasaan anak usia TK di TK Taska pada siswa-siswi, para guru, dan wali murid sehingga dapat membuat minuman fungsional rempah dan memahami pentingnya minuman fungsional ini agar anak-anak usia TK dapat tumbuh sehat dan optimal.  Berdasarkan hasil kegiatan pengabdian pada masyarakat ini disimpulkan bahwa para responden, yaitu guru dan orang tua murid Taman Kanak-Kanak Tiska, mengerti, memahami, dan dapat membuat minuman rempah fungsional dan mengerti tentang kegunaannya.

Abstract

Coffee skin is an agricultural byproduct that has the potential to be processed into value-added food products such as jam. Coffee skin can be made into jam because it has a pectin content of 27.20-57.24%. The study aims to determine the effect of the addition of citric acid and white crystal sugar, as well as their interaction on the chemical and sensory properties of coffee skin jam. The study was arranged in a Completely Randomized Block Design (CRBD) with two factors and three replications. The first factor was the addition of citric acid with 2 concentration levels of 0.5% (A1) and 0.9% (A2) and the second factor was the addition of white crystal sugar with 4 concentration levels of 40% (G1), 50% (G2), 60% (G3), and 70% (G4). Data homogeneity was tested using the Bartlett test, data addition using the Tuckey test, then the data were analyzed for variance to determine the effect between treatments and further analysis using Honestly Significant Difference (HSD) at the 5% level. The results showed that the interaction of citric acid and white crystal sugar had a very significant effect on water content, color (L*, a*, b*), color score, taste, texture and overall acceptance. The concentration of white crystal sugar had a very significant effect on the total soluble solids and spreadability of coffee skin jam. Treatment A2G3 (AS 0.9% and GK 60%) was the most preferred combination of citric acid and white crystal sugar coffee skin jam.
