“…Kadar karbohidrat dari sampel madu ditentukan dengan cara selisih, yang dihitung dengan cara mengurangkan 100% dengan persentase air, lemak, protein, dan abu (satuan dalam %). Perhitungan jumlah energi yang diperoleh dilakukan dengan menjumlahkan hasil pengukuran protein dan karbohidrat kemudian dikalikan 4, sedangkan perhitungan lemak dikalikan 9 (Lestari & Dewi, 2019).…”

Penelitian ini bertujuan untuk memetakan karakteristik fisikokimia dan mutu glikemik madu. Sampel madu yang digunakan ada tiga yang mewakili perbedaan lebah dan pohon sarang lebah. Madu kelulut (MK) mewakili madu yang dihasilkan oleh lebah tanpa sengat (Trigona sp), sedangkan madu tikung (TK) oleh lebah dengan sengat (Apis sp). Madu tikung yang digunakan diperoleh dari 2 pohon sarang yang berbeda, yang disebut MT1 dan MT2. Karakteristik fisikokimia dilakukan uji kadar air, warna, viskositas, kadar abu, protein, lemak, karbohidrat, profil gula (glukosa, fruktosa, sukrosa, laktosa), total asam, dan asam galakturonat. Mutu glikemik dilakukan dengan analisis indeks glikemik dengan relawan sehat. Analisis multivariat dilakukan dengan PCA untuk menentukan pengelompokkan, kemudian pengelompokan dilanjutkan sebagai kelas pada OPLS-DA. Hasil penelitian menunjukkan terdapat 9 karakteristik penting yang membedakan madu Kelulut dengan Tikung, yaitu berurutan dari yang sangat penting, total asam, viskositas, fruktosa, glukosa, IG, b, L, a, dan laktosa. Madu Kelulut memiliki karakteristik dominan, yaitu total asam dan glukosa yang tinggi, serta viskositas yang rendah. Madu Tikung dari lokasi sarang yang berbeda dapat memiliki karakteristik yang berbeda terutama, warna kemerahan dan kecerahan, IG, dan laktosa. Penelitian ini menunjukkan IG memiliki korelasi negatif dengan glukosa dan total asam, akan tetapi berkolerasi positif dengan laktosa.

The study aimed to obtain sorghum mutant lines from the Numbu variety resistant to 3 major diseases (leaf rust, leaf spot, and anthracnose). The research was conducted at the ICERI Experimental Garden. The treatments were arranged using a Randomized Block Design with 3 replications with materials tested were five mutant lines derived from a Numbu variety (lines MM-5, MB-3. MB-5. MM-3, MM-4) and resistant comparison varieties (Kawali and Numbu) and check susceptibility lines (Super 2 and line SRN48-1) as a comparison for each disease. The results showed that the five test genotypes had high resistance to 3 main sorghum diseases. The MB-3 and MB-5 mutant lines were resistant to leaf rust and leaf spot Cercospora, and moderately resistant to anthracnose. The lowest infection rate of leaf rust disease was in the MB-5 line, which was 0.0019. This illustrates the low development of rust disease in this line. While the other 3 strains (MM-3, MM-4, and MM-5) consistently reacted moderately resistant to the 2 main diseases of sorghum (rust and anthracnose).

“…Positive genetic alterations have been produced in several plants through the application of gamma-ray mutagenesis techniques (Lestari et al, 2016;Chaudhary and Deshmukh, 2019;Anne and Lim, 2020;Lestari, 2021). Mutations have produced new and enhanced agronomic features relative to the wild types or parent plants, demonstrating promise in producing new plant varieties.…”

Importance of the work:The sorghum mutant "Gando Keta"is known to have a sticky texture but low production levels, with mutations expected to produce plants with improved yields. Objectives: To use gamma radiation to produce sorghum mutants of "Gando Keta" with high yield and fluffy texture. Materials & Methods: Explants (2 mm high, aged 3 d) were exposed to radiation doses in the range 10-100 Gy in 10 Gy increments. The shoots were acclimatized and their variability was observed. Then, 30 2 nd generation mutant (M2) plants for each dose of 40 Gy, 50 Gy, 60 Gy and 70 Gy were planted and observed for plant height, panicle diameter, panicle length, wet and dry panicle weights and seed weight. Results: Analysis of variance showed significant differences in mean plant height, stem diameter and panicle length. Radiation with doses of 40 Gy and 50 Gy produced significantly greater plant heights than those irradiated with a dose of 70 Gy. Observations on the growth characteristics of the six selected genotypes showed that the genotype "GK50-18" had a significantly greater plant height compared to M2, while the genotypes "GK60-13" and "GK70-5" were significantly lower than the M2 population. Seed weight had wide genetic variability and high heritability, so selection should be based on seed weight characters using the pedigree technique. Amylose analysis identified genotypes with lower amylose contents that should be further tested to determine the stability of the results. Main finding: Selection on the 2 nd generation mutant (M2) population obtained six genotypes with higher productivity: "GK50-18", "GK50-19", "GK60-11", "GK60-13", "GK60-9" and "GK70-5".
