“…The results indicated that the substitution of coconut dregs and avocado seed flour affected the brightness level (L*) of white bread. This was because the higher substitution of coconut dregs flour produced darker bread (Pusuma et al, 2018) due to the high-fat content of 15.89% (Putri, 2014), which easily oxidized and change the color of the fat to be more concentrated (Panjaitan et al, 2020). The substitution of 5% avocado seed flour also affected the brightness of white bread.…”

Analysis of the relationship between physical properties and consumer acceptance, which is commonly influenced by sensory properties is crucial in delivering a high-quality food product. Therefore, this study aimed to analyze the effect of physical properties, including hardness, adhesiveness, dough expansion, specific volume, color intensity (L*, a*, b*, and °hue), browning index, and analysis of consumer acceptance by employing Partial Least Squares (PLS) regression. The analysis focused on high-fiber white bread made by substituting coconut dregs and avocado seed flour with different ratios, denoted as P0 (control), P1 (90% wheat flour: 5% coconut dregs flour: 5% avocado seed flour), P2 (85% wheat flour: 10% coconut dregs flour: 5% avocado seed flour), P3 (80% wheat flour: 15% coconut dregs flour: 5% avocado seed flour), P4 (75% wheat flour: 20% coconut dregs flour: 5% avocado seed flour), and P5 (70% wheat flour: 25% coconut dregs flour: 5% avocado seed flour). The results showed that consumer preferences had a positive correlation with the physical properties of white bread, including hardness, adhesiveness, dough expansion, specific volume, as well as colors L*, and °hue, while, a*, b*, and had a negative correlation with the browning index. The circular correlation analysis between physical properties and consumer acceptance indicated that the substitution of 25% coconut dregs flour and 5% avocado seed flour in white bread was accepted by consumers.

“…Gracilaria sp. juga mengandung senyawa antibakteri yaitu alkaloid, flavanoid dan steroid yang terbukti mampu menghambat pertumbuhan bakteri (Panjaitan et al, 2020). Selain peran ekonomis juga memiliki peran ekologis yaitu sebagai pengikat nitrogen, fosfor dan karbon yang sangat baik, sehingga dapat menjaga keseimbangan ekosistem perairan (Komarawidjaja, 2005;Arbit et al, 2018).…”

Pertumbuhan Rumput Laut Gracilaria sp. terhadap Variasi Dosis Media Walne

2022

View full text Add to dashboard Cite

Gacilaria sp. merupakan sumber agar yang sangat laku di pasaran baik dalam negeri maupun luar negeri. Untuk memenuhi permintaan pasar maka stok bibit harus terpenuhi salah satunya dengan menggunakan metode vegetatif. Nutrien merupakan salah satu faktor penting dalam proses metode ini. Jika media tumbuh tidak mencukupi kebutuhan perlu dilakukan pemupukan. Penelitian ini bertujuan untuk mengetahui pengaruh variasi dosis media Walne pada pertumbuhan Gracilaria sp. dan mengetahui dosis optimal sebagai sumber nutrien. Metode yang digunakan adalah metode eksperimental laboratoris dengan Rancangan Acak Lengkap (RAL) menggunakan 5 perlakuan 1 kontrol dan 3 ulangan, antara lain perlakuan A (kontrol), B (0,5 ml/L), C (1 ml/L), D (2 ml/L), E (4 ml/L) dan F (8 ml/L). Parameter yang diamati adalah berat eksplan, jumlah tunas, panjang tunas, pertumbuhan berat mutlak, laju pertumbuhan spesifik dan kualitas air media. Data dianalisis menggunakan analisis One-Way ANOVA dilanjutkan uji Tukey dan Games-Howell. Hasil penelitian menunjukkan rata-rata berat, jumlah tunas dan panjang tunas terdapat perbedaan yang signifikan (p < 0,05). Rata-rata pertumbuhan berat mutlak tertinggi pada perlakuan E (4 ml/L) yaitu 0,07 ± 0,01 g/hari dan laju pertumbuhan spesifik tertinggi pada perlakuan E (4 ml/L) 2,24 %/hari. Hal ini diduga nutrien bekerja secara optimal. Hasil pengamatan pH (4 – 7,92), salinitas (23 – 32 ppt) dan suhu (27 – 31 oC). Dosis 4 ml/L merupakan konsentrasi optimal karena pada dosis ini Gracilaria sp. berpengaruh secara signifikan. Gacilaria sp. is a source of agar which is very salable in the market both domestically and abroad. To meet market demand, the stock of seeds must be met, one of them by using the vegetative method. Nutrients are one of the important factors in the process of this method. If the growing media is not sufficient, fertilization needs to be done. This study aims to determine the effect of variations in the dose of Walne media on the growth of Gracilaria sp. and knowing the optimal dose as a source of nutrients. The method used is a laboratory experimental method with Completely Randomized Design (CRD) using 5 treatments 1 control and 3 replications, including treatment A (control), B (0,5 ml/L), C (1 ml/L), D (2 ml/L), E (4 ml/L) and F (8 ml/L). Parameters observed were explant weight, number of shoots, shoot length, absolute weight growth, specific growth rate and water quality of the media. Data were analyzed using One-Way ANOVA analysis followed by Tukey and Games-Howell tests. The results showed that there were significant differences in the average weight, number of shoots and shoot length (p < 0,05). The highest average absolute weight growth was in treatment E (4 ml/L) which was 0,07 ± 0,01 g/day and the highest specific growth rate was in treatment E (4 ml/L) 2,24%/day. It is suspected that nutrients work optimally. The results were observed for pH (4 – 7,92), salinity (23 – 32 ppt) and temperature (27 – 31 oC). The dose of 4 ml/L is the optimal concentration because at this dose Gracilaria sp. significant effect.

Status kesuburan tanah merupakan faktor penting yang menentukan keberhasilan pertumbuhan dan produksi tanaman. Kesuburan tanah menggambarkan kemampuan tanah mendukung pertumbuhan dan produksi tanaman. Ketersediaan unsur hara di dalam tanah terus berkurang akibat dari pengambilan hasil tanam atau pengurasan hasil panen sehingga tanah perlu dipupuk untuk menggantikan unsur hara yang terangkut dan untuk mempertahankan tingkat produktivitas lahan. Pemupukan tanah dapat dilakukan menggunakan pupuk anorganik dan atau pupuk organik. Penelitian ini bertujuan untuk memperoleh pupuk organik Eco Glasum yang ramah lingkungan. Eco Glasum merupakan pupuk kompos modifikasi berbentuk padat yang terdiri atas 3 jenis rumput laut yaitu Eucheuma cottoni, Glacilaria sp., Sargassum sp. dan dikombinasikan dengan ekstrak bawang merah. Penelitian ini dilaksanakan di KP. Fakultas Pertanian, Peternakan, dan Perikanan Universitas Muhammadiyah Parepare pada bulan Juni 2023. Parameter amatan terdiri atas tekstur, warna, dan aroma. Hasil penelitian menunjukkan bahwa pembuatan pupuk organik yang berbahan dasar kombinasi dari rumput laut yang dimodifikasi dengan ZPT alami memiliki tektur yang remah, warna gelap dan tidak beraroma. Gelap ini menunjukkan bahwa pupuk organik memiliki tingkat kematangan yang optimal. Soil fertility status is an important factor that determines the success of plant growth and production. Soil fertility describes the ability of the soil to support plant growth and production. The availability of nutrients in the soil continues to decrease due to harvesting or depletion of crops, so the soil needs to be fertilized to replace the transported nutrients and to maintain the level of land productivity. Soil fertilization can be done using inorganic fertilizer and/or organic fertilizer. This research aims to obtain Eco Glasum organic fertilizer which is environmentally friendly. Eco Glasum is a solid modified compost fertilizer consisting of 3 types of seaweed, namely Eucheuma cottoni, Glacilaria sp., Sargassum sp. and combined with red onion extract. This research was carried out in KP. Faculty of Agriculture, Animal Husbandry and Fisheries, Muhammadiyah University, Parepare in June 2023. Observed parameters consist of texture, color and aroma. The results of the research show that making organic fertilizer made from a combination of modified seaweed with natural PGRs has a crumbly texture, dark color and no aroma. This darkness indicates that the organic fertilizer has an optimal level of strength.
