Abstract

Kappaphycus striatum, a red seaweed rich in sulfated polysaccharides, serves as a promising raw material for carrageenan production due to its favorable gelling and stabilizing properties. This study aimed to investigate the effect of different extractor solvent ratios on the physicochemical characteristics of refined carrageenan derived from K. striatum. Refined carrageenan was extracted from semi-refined material using hot water at solvent-to-seaweed ratios of 1:40, 1:50, and 1:60, followed by precipitation with isopropyl alcohol. The parameters assessed included moisture content, yield, gel strength, sulfate content, and viscosity. Moisture content remained relatively constant across treatments (?10–11%) and complied with FAO/JECFA standards. In contrast, yield and gel strength increased significantly with higher solvent ratios, with the highest values observed at the 1:60 ratio (30.04% yield; 1090.23 g/cm² gel strength). Sulfate content also increased, peaking at 21.42% for the same treatment. Viscosity was highest at the 1:50 ratio (87 cP), indicating a favorable balance between molecular hydration and structural integrity. All treatments produced carrageenan within acceptable quality standards for commercial use. The results demonstrated that the extraction solvent ratio played a critical role in determining the performance characteristics of refined carrageenan. Therefore, adjusting the water-to-seaweed ratio during extraction may serve as a practical approach to optimize carrageenan properties for targeted industrial applications.Contribution to Sustainable Development Goals (SDGs): SDG 1 :No povertySDG  9: Industry, Innovation and InfrastructureSDG 12: Responsible Consumption and ProductionSDG 14: Life Below Water

Abstract

Fermentasi biji kakao dapat memengaruhi kualitas dengan penurunan senyawa fenolik dan aktivitas antioksidan. Tujuan dari artikel ini adalah untuk mengetahui karakteristik biji kakao yang difermentasi dan tidak difermentasi. Metode yang digunakan dalam penelitian ini adalah studi literatur yang berasal dari Google Scholar, Science Direct, Pubmed dan Research Gate. Adapun pemilihan jurnal yang disitasi telah melalui proses skrining berdasarkan kriteria inklusi, khusus dan eksklusi. Fermentasi biji kakao merupakan tahap penting dalam pengolahan pascapanen kakao, melibatkan suksesi mikrobial dari khamir, bakteri asam laktat (LAB), hingga bakteri asam asetat (AAB), serta berbagai spesies Bacillus dan fungi filamen. Proses ini tidak hanya menghilangkan lendir pada biji kakao, tetapi juga mempersiapkan biji melalui enzim yang memodifikasi warna, rasa, dan aroma. Hasil fermentasi biji kakao juga memengaruhi komposisi kimia, dengan kandungan lemak, protein, pati, sukrosa, theobromin, kafein, dan senyawa polifenol yang berubah. Biji kakao mengandung komponen fenolik, flavanol, antosianidin, proantosianidin, epikatekin, katekin, serta zat psikoaktif seperti teobromin dan kafein. Selain itu, biji kakao menghasilkan senyawa volatil yang berkontribusi pada aroma dan rasa produk akhir, seperti 3-hidroksi-2-butanon, 1-metilpiperidin, dan 2,6-dimetilpirazin. Perubahan warna biji kakao menjadi coklat terjadi akibat oksidasi polifenol, yang membentuk tanin dan memberikan warna coklat. Studi komponen volatil pada berbagai klon kakao menunjukkan variasi, dengan beberapa komponen seperti asam asetat, asam tetradekanoat, dan pirazin muncul pada setiap klon yang telah mengalami proses fermentasi. Senyawa volatil dan non-volatil, bersama dengan komponen kimia lainnya, memberikan kontribusi pada karakteristik warna, rasa, dan aroma pada biji kakao yang dihasilkan

Abstract

Homemade tomato sauce products have the advantage of having a composition that can be ensured to contain minimal harmful chemicals. However, like other processed products, of course, the product will experience a decrease in quality along with the length of storage time. This study aims to determine changes in the quality of tomato sauce produced on a home scale (homemade ketchup) during one month of storage at storage temperatures of 10oC, 250oC, and 350oC. The method used to predict shelf life is the Arrhenius calculation model, which observes changes in pH, aw, and Total Microbes. The findings showed that the pH of tomato sauce tended to decrease with the length of storage time. The number of microbes increased with the increasing temperature and length of storage. Meanwhile, temperature and length of storage did not affect water activity. However, aw tends to increase with the temperature and length of storage. The results of estimating the shelf life with the Arrhenius model based on the water activity (aw) parameter showed that the shelf life of the sauce was 151.75 days with a quality decline rate of 0.001068/day at a storage temperature of 10oC; 96.07 days with a quality decline rate of 0.001685/day at a storage temperature of 25oC and 72.6 days with a quality decline rate of 0.002227/day at a storage temperature of 35oC. The implications of this study indicate that storage at 10oC can extend the shelf life of both tomato sauce products, so producers and consumers need to consider the optimal storage temperature based on the results of this study.

Abstract

Although taro is widely grown in Indonesia, it is one of the underutilized crops which is a good source of nutrition. one part of taro that is rarely utilized is the leaves. The objective of this research is to determine the effect of glucose syrup and gelatin concentrations on the organoleptic properties (preference for color, taste, and texture) of soft candy made from taro leaf extract. The method used in this research is experimental which is arranged in a Completely Randomized Factorial Design (CRD) with two factors, which are The concentrations of are (25%, 35%, 45%) and the concentrations of gelatin are (20%, 25%, 30%). Each treatment being repeated three times. The obtained data were analyzed using ANOVA (analysis of variance), and Duncan’s test was conducted if significant differences were obtained. The results shows that soft candy with 35% glucose syrup and 25% gelatin had the highest preference for color. The formulation with 35% glucose syrup and 30% gelatin was most preferred for aroma. The formulation with 45% glucose syrup and 30% gelatin received the highest scores for texture (3.90±0.308) and flavor (3.95±0.63). This research demonstrates that optimizing glucose syrup and gelatin concentrations in soft candies made from underutilized taro leaf extract can significantly enhance specific sensory attributes like texture and flavor. This study can contribute in providing valuable insights for future product development and highlighting the potential of taro leaves as a valuable food ingredient.

Abstract

Honey has many benefits. Thus, honey counterfeiting often occurs with the ever-increasing demand. However, many do not know how to distinguish between real and fake honey, even honey breeders and hunters find it difficult to tell the difference. The honey used to test the quality of honey is honey produced by Apis dorsata bees or wild bees, the nectar consumed by these bees is the kesambi tree, the kesambi tree that grows a lot on the slopes of Mount Tambora, Bima district. Honey contains a lot of antioxidants such as vitamin C, pinocembrin, chrysin, pinobaksin, catalase, and many other ingredients that are very beneficial for the health of the body. Testing the authenticity of honey using two sensors, namely a gas sensor and a color sensor, the tool has been connected to a database and web application to display test data. The web application can be accessed from any location as long as it is connected to the internet network. The results of the research are the ideal distance for measurements is carried out as far as 2 cm. The success rate in testing pure honey with a mixture of honey has different values, such as the value of pure honey has a gas sensor voltage of 3.3 volts while the value of mixed honey with 50% pure honey and 50% sugar, the value of the gas sensor voltage is 2.54 volts. Mixed honey has a voltage below 3 volts. The results of the color sensor test, namely the sensor output have different values, the RGB value for pure honey is red 206, green 246, and blue 182 while the RGB value for mixed honey is for 20% pure honey and 80% sugar mixture produces an RGB value of Red 156, Green 210, Blue 171.

Abstract

Cocoa plantations face a number of complex and interrelated challenges. Several critical problems threatening the sustainability of cocoa farming include declining productivity due to pest infestations, inefficiencies in the management of cocoa pod husk waste, weak adoption of agronomic practices such as pruning and sanitation, and the occurrence of land degradation caused by decreasing soil organic matter content. The activities conducted included training on the production of liquid organic fertilizer from Gamal (Gliricidia sepium) leaves, instruction on proper pruning and plantation sanitation techniques, processing cocoa pod husk waste into compost, and the creation of IoT-based biopori (absorption holes). The implementation results demonstrated a significant increase in farmers' knowledge and skills, particularly in the aspects of plantation sanitation and the techniques for making organic fertilizers and pesticides from Gamal leaves. Program evaluation revealed a marked improvement in understanding: the category for 'basic knowledge' increased from 16.80 percent to 44.00 percent, and the 'comprehensive knowledge' category rose from 0.07 percent to 36.41 percent. Conversely, the 'no knowledge' category decreased from 48.40 percent to 12.33 percent. The implication of this community service project is that the empowerment program was effective in enhancing farmers' comprehension and encouraging the adoption of sustainable agricultural practices.
