“…Penumpukan gula terjadi dimulai dari paling bawah hingga atas. Jika tingkat kandungan gula ruas bawah dan atas sama, maka tebu dikatakan masak optimal (Supriyadi et al, 2018) Tabel 5 memperlihatkan bahwa produktivitas tanaman tebu di Cangkringan memiliki hubungan yang sangat kuat dan signifikan terhadap jumlah batang per rumpun, jumlah daun hijau dan diameter batang. Jumlah batang per rumpun pada lahan yang diberi blotong jauh lebih tinggi dibandingkan pada lahan tanpa pemberian blotong, meskipun brix memberikan hasil yang sama.…”

Tebu (Saccharum officinarum L) merupakan tanaman rumput-rumputan yang telah dibudidayakan di lebih dari 90 negara, baik di negara tropis dan subtropis. Tebu di Indonesia dimanfaatkan utama sebagai bahan baku dalam industri gula. Saat ini budidaya tebu banyak dilakukan pada lahan marjinal (pasiran) sehingga hasil yang didapatkan kurang maksimal. Penelitian ini dilaksanakan di Dusun Kiaran, Kecamatan Cangkringan, Kelurahan Wukirsari dan varietas tebu yang digunakan merupakan Bululawangan (BL). Penelitian ini menggunakan rancangan penelitian RAK 1 faktor yaitu penambahan blotong, dengan dua taraf yaitu B0 (tanpa blotong) dan B1 (dengan blotong) dengan tiga ulangan. Dosis blotong yang ditambahkan adalah 11,25 ton/ha blotong basah. Analisa tanah dan tanaman serta hasil tanaman dilakukan untuk melihat pengaruh pemberian blotong. Hasil penelitian menunjukkan bahwa blotong basah dari PG Madukismo memiliki kandungan pH yang netral, C organik tinggi dan memiliki kandungan hara baik N, P, K, Ca, Mg, dan Na. Terdapat hasil yang signifikan lebih tinggi pada tebu yang ditanam di lahan yang ditambahkan blotong dibandingkan pada tebu yang ditanam pada lahan tanpa penambahan blotong, pada parameter diameter batang, jumlah batang per rumpun, jumlah daun hijau dan produktivitas tebu. Kadar lengas tanah dan berat volume tanah memberikan hasil yang berbeda nyata antara lahan yang diberi blotong dan tanpa penambahan blotong. Penambahan blotong memberikan peningkatan yang signifikan pada parameter produksi brix dan produktivitas tebu, dengan peningkatan produktivitas hingga 208%. Pemberian blotong sebagai bahan pembenah tanah menjadi salah satu alternatif dalam upaya peningkatan produktivitas tebu di lahan pasiran.

Indonesia is the seventh largest sugar producer in the world. Monoculture sugarcane cultivation has been practiced since the Dutch era, especially in the Entisols, Inceptisols and Vertisols soil orders. The field research with this multilocation design aims to determine the effect of the monoculture sugarcane cultivation period (1–10, 11–20 and 21–30 years) on the growth and yield of sugarcane plants under the three soil orders. Analysis of variance (ANOVA) at a 5% significance and correlation was conducted to determine the effects of soil orders and monoculture period. The results showed that there were significant interactions between monoculture period and soil order on leaf fresh weight, leaf dry weight, root fresh weight, plant height, stalk diameters, number of stalks, leaf area, number of green leaf, root CEC, root length, root surface and root area. There was no interaction between monoculture period and soil order on stalk fresh weight, stalk dry weight, root dry weight, number of nodes. The sucrose content of sugarcane in Entisols at the 1–10 years monoculture period significantly lower (6.03%) compared to 11–20 years period (7.37%) and 21–30 year (7.79%), whereas at the 1–10 years monoculture period in Inceptisols and Vertisols (7.99% and 8.04 %) was significantly higher than that of Entisols (6.03%). Sugarcane productivity at monoculture period 1–10 years in Entisols significantly lowest (49.38 t/ha) compared to Inceptisols (54.82 t/ha) and Vertisols (63.05 t/ha) at the same period, while the 21–30 years period on Vertisols significantly highest (76.18 t/ha) compared to 11–20 years period (68.73 t/ha) and 1–10 years period (63.05 t/ha) in same soil order. These conditions indicate that the effect of long-term monoculture cultivation of sugarcane on the growth and yield of sugarcane varies, depending on the soil order as the grow medium and root parameters have the highest correlation with sugarcane yield. Land management to improve the root area is necessary for optimal plant growth.

Glucose in sugarcane affected cane yield, recoverable sugar, and sugar yield. Glucose is available since the formation of the stems and stored until sugarcane is ready to be harvested. Information regarding the need for glucose to form sugarcane plant tissue is still not widely available. So, research was conducted to determine the quantity of glucose to form sugarcane plant tissue and its relation to cane yield, recoverable sugar, and sugar yield obtained. The research was carried out at the Karangploso Research Station and Laboratory of Plant Chemistry, Indonesian Sweeteners and Fiber Crops Research Institute, in July 2016–September 2017. A split plot design with two factors and three replications was utilized. The main factor was the growth phases, namely, the vegetative phase and maturity phase, while the other factor was sugarcane varieties, namely, PS-881 (early mature), JR-01 (early-middle mature), Kenthung (early-middle mature), and Bululawang (middle-late mature). The measurements of nitrogen, carbon, and the ash content of the leaves and stems were at 5 months (representing the growth period) and 9 months (representing the ripening period). The results showed that quantities of 1.962–2.160 kg and 2.066–2.113 kg glucose were required to form each kg of leaf and stem tissue depending on the growth phase and variety. Glucose requirements in the maturing phase affected the cane yield, recoverable sugar, and sugar yield as much as by 51.48%, 57.60%, and 58.26%, respectively.
