Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh penambahan tepung rumput laut terhadap karakteristik dan indeks glikemik beras putih. Beras putih merupakan makanan pokok masyarakat Indonesia dan diketahui memiliki indeks glikemik yang tinggi. Salah satu upaya yang dapat mengubah karakteristik dan indeks glikemik beras putih adalah dengan penambahan tepung rumput laut. Desain penelitian ini adalah eksperimen yang dilakukan dalam dua tahap: (1) Menentukan produk yang paling diterima secara organoleptik menggunakan Rancangan Acak Lengkap (RAL) dengan empat perlakuan (penambahan tepung rumput laut 1%, 2%, 3% dan 4%), yang dianalisis secara statistik menggunakan Analisis Varians (ANOVA); dan (2) Membandingkan produk dengan penambahan tepung rumput laut terbaik terhadap kontrol dari segi organoleptik, kimia, dan fisik menggunakan uji-t sampel independen, sedangkan data indeks glikemik disajikan secara deskriptif. Hasil penelitian tahap 1, menunjukan perlakuan terbaik adalah perlakuan C (penambahan tepung rumput laut 3%). Penelitian tahap 2 menunjukkan tidak ada perbedaan tingkat penerimaan secara organoleptik (p>0,05) antara kontrol dengan perlakuan terbaik. Sedangkan kadar air, abu, lemak, protein, dan serat lebih tinggi pada produk C dibandingkan dengan kontrol (p<0,05). Kadar guka total dan kadar karbohidrat lebih rendah dari control (p<0,05). Tepung rumput laut efektif menurunkan indeks glikemik beras putih, dimana nilai Indeks glikemik (IG) produk C adalah 42,17 dalam kategori rendah, sedangkan IG kontrol adalah 58,03 dalam kategori sedang

Abstract

Noodles are a food that all groups love. Many noodles sold in the community use natural dyes, although many still use synthetic dyes. This condition can be seen by the public starting to understand the importance of maintaining health, especially food coloring, so many noodles in circulation use natural coloring. Natural dyes are safe to use and have functional properties that are not available from artificial dyes, but have the weakness of being easily damaged during processing, especially at high temperatures. Generally, processed noodles use high temperatures in the process. Therefore, this research aims to identify the noodle processing process that causes the greatest damage to the color quality of the noodles produced. This research used a Completely Randomized Design with four treatments: boiling, steaming, steaming and drying, and steaming and frying. Noodle dough was used as a control in the treatment. This research used three replications. Observations were made on antioxidant activity, polyphenol, anthocyanin, betacyanin, and color quality. Based on this research, the noodle processing that provides the best colour quality is the steaming treatment with antioxidant activity of 21.69%, polyphenol content of 34.99 mg GAE/100 g, anthocyanin content of 40.72 mg/100, betacyanin content of 39.25 mg/100, and colour L* = 45.73, a* = 13.54 and b* = 9.86.

Abstract

This study aims to analyze the types of dominant contaminant molecules, identify the factors causing contamination, compare pesticide residue characteristics between regions, examine the relationship between residues and cultivation or processing practices, and formulate mitigation strategies for pesticide residues in cinnamon (Cinnamomum burmannii) commodities in Jambi and West Sumatra Provinces. The analysis revealed seven dominantly detected contaminant molecules, namely phenylphenol 2-, propamocarb, chlorpyrifos, fipronil, fipronil (sum), isoprocarb, and diethyl-m-toluamide (DEET), each with a detection frequency above five percent. These molecules are suspected to originate from pesticide applications, environmental pollution, and human activities. Statistical analysis using the Mann-Whitney U Test showed that 12 molecules had significantly higher residue levels in samples from West Sumatra compared to Jambi (p < 0.05), including ametryn, anthraquinone, carbofuran and its fractions, ethion, ethylene oxide, griseofulvin, nicotine, propamocarb, chlorpyrifos, DEET, and isoprocarb, indicating a clear regional difference. Jambi samples classified as high-grade had lower residues, reflecting that high quality can be achieved through sustainable farming practices such as integrated pest management and natural drying, rather than intensive chemical treatments. These findings suggest a negative correlation between visual quality and residue levels. Recommended mitigation strategies include the application of IPM, farmer education, post-harvest washing and drying, and environmental remediation. The 2021–2025 trend shows residue fluctuations peaking in 2023 before declining, highlighting the importance of regular monitoring. This research provides a scientific basis to support food safety, sustainable production, and enhance the export competitiveness of Indonesian cinnamon Keywords- pesticide residues; cinnamon; cinnamomum burmannii; Jambi; West Sumatra

Abstract

The use of swampland faces various challenges, such as flooded soil conditions, high acidity levels, and limited access to agricultural facilities and infrastructure. One of the solutions to overcome these challenges is the modernization of agricultural tools and machinery (alsintan), especially the use of hand tractors as an efficient soil tillage tool and in accordance with the characteristics of swampland. Tapus Village is one of the administrative areas located in Pampangan District, Ogan Komering Ilir Regency, South Sumatra Province. Tapus Village already has agricultural tools and machinery in the form of hand tractors that are quite adequate, but their use is still not optimal. The purpose of this study is to determine the role and strategy in optimizing hand tractor agricultural tools and machinery to support the management of swampland (OPLA) in Ogan Komering Ilir Regency in a more optimal and sustainable manner. In this study, methods were used in the form of literature study, gap analysis, SWOT (Strength, Weakness, Opportunity, and Threat) analysis, conducting needs and opportunities studies (KKP) and conducting observations and deep interviews with resource persons using questionnaires. The results of the study show that the optimization strategy of Alsintan hand tractor to support OPLA in Tapus Village can be carried out through the empowerment of farmers through training, socialization, and education on the use and maintenance of hand tractors, increasing the capacity of special operators, utilizing Alsintan hand tractors that are available, increasing UPJA and Alsintan workshops in Tapus Village. It is hoped that the results of this research can support the sustainability of the implementation of the strategy so that it can be carried out efficiently and effectively.

Abstract

The use of coconuts produces agricultural waste such as coconut fiber. Immature coconut fiber and mature coconut fiber are lignocellulosic materials that can still be utilized, one of which is by processing them into furfural. Furfural is a clear liquid with a distinctive almond aroma that is widely used as an additive by the chemical industry. The purpose of this study was to determine the effect of the level of coconut fiber maturity with various catalyst concentrations and differences in reaction time on furfural yield. This study used two samples: mature coconut fiber and immature coconut fiber. The concentration variations used were 10%, 12%, and 14%. The time variations used were 20 and 30 minutes. From the results, it can be seen that the concentration, reaction time and type of raw material showed no significant effect on furfural yield. Young coconut fiber produced a higher yield than mature coconut fiber.

Abstract

The success rate in the seedling process is ofte hampered by inappropriate watering, which can cause the seedlings to rot and die. To overcome this problem, an efficient watering system with a high degree of precision is required. Mist irrigation is one of the appropriate methods because micro-sized water droplets are sprayed to maintain air humidity and reduce the rate of transpiration. This study aims to optimize the application of mist irrigation by evaluating the effect of nozzle height variations on plant growth. Using an experimental method, the variations included nozzle heights of 20 cm, 25 cm, and 30 cm. The parameters measured in this study included water discharge, plant height, number of leaves, and leaf area. The results showed that a watering height of 25 cm produced the best plant growth. The results of this study show that specific adjustment of the nozzle height is very important for improving the efficiency of mist irrigation in the seedling process. Keywords: mist irrigation, seedling, green mustard

Abstract

Kabupaten Jember merupakan daerah potensi kopi terbesar kedua di Jawa Timur dan salah satu kopi yang dibudidayakan yaitu Kopi Robusta. Bentuk diversifikasi produk kopi robusta diantaranya adalah pembuatan permen jeli. Permen jeli yang bertekstur lunak dan manis serta digemari oleh semua kalangan masyarakat dapat dijadikan sebagai alternatif camilan bagi penderita diabetes mellitus (DM). Namun, rasa manis dari gula (sukrosa) yang berlebih dapat memperparah penderita sehingga dibutuhkan pemanis pengganti yang aman bagi kesehatan, yaitu stevia. Stevia merupakan pemanis yang disarankan untuk penderita diabetes karena memiliki kalori yang rendah dan tidak memberikan efek samping. Oleh karena itu, penelitian ini bertujuan untuk mengetahui pembuatan permen jeli kopi robusta dengan formulasi yang tepat dan sesuai sebagai alternatif camilan bagi penderita DM. Metode penelitian yang dilakukan yaitu eksperimental di laboratorium dengan variasi perlakuan stevia dan sukrosa (3:0, 2:1, 1:2, dan 0:3) yang akan dilakukan ulangan sebanyak 3 kali ulangan. Hasil penelitian pada uji organoleptik menunjukkan adanya perbedaan tingkat kesukaan panelis terhadap warna dan rasa serta tidak terdapat perbedaan tingkat kesukaan panelis terhadap aroma dan tekstur permen jeli kopi Robusta. Selain itu, secara keseluruhan ada perbedaan yang signifikan terhadap tingkat kesukaan panelis pada permen jeli kopi Robusta. Berdasarkan uji tekstur dan kadar gula didapatkan hasil tertinggi pada perbandingan konsentrasi ekstrak stevia dan sukrosa (0:3) yaitu berturut-turut sebesar 60,60 g dan 17,46%.
