ABSTRACT<br />    <br />Sugar cane is a strategic commodity for the Indonesian government as raw material for the national sugar industry. Cultivation of sugar cane has been shifted to dry areas dominated by Inceptisol, Vertisol, and Ultisol soil. These conditions require certain clones to obtain high sugar yield. New improved varieties have been developed and 8 early-mid maturiting clones have been obtained. The study was aimed to evaluate and obtain earty-mid maturing clones with higher sugar yield than the existing varieties in dry land of Inceptisol soil. The study was conducted at the Karangploso Experimental Station, Malang from July 2015 to September 2016. The study was arranged in a randomized block design with three replications. The treatment consistsed of eight clones of early to mid maturing sugarcane clones and one control variety (Kenthung). The eight clones were (1) PS 04 117, (2) PS 04 259, (3) PS 04 129, (4) PS 05 258, (5) PS 06 391, (6) PS 06 370, (7) PS 06 188, and (8) JR 01. The results showed that three clones (PS 06 188, PS 05 258 and JR 01) produced higher sugar yield (10.45-11.88 ton ha-1), and the other clones showewd lower sugar yield (6.55-9.37 ton ha-1) than that of Kenthung variety (9.16 ton ha-1).PS 06 188 and PS 05 258 clones obtained the highest sugar yield of 11.88 and 11.49 ton ha-1, respectively.<br /><br />Keywords: dry land, performance, Saccharum officinarum,  sugar content, variety<br /><br />

The downside of fossil fuels as non-renewable energy resources in Indonesia has led to invent alternative energy resources. One of alternative sources is biofuels, which are derived from organic compound that originated from plants and living creatures. Here, we used sorghum as a source of biofuels, but current knowledge of sorghum cultivation on dry land is limited. This study aims to determine the influence of sorghum genotypes on their growth and yield in a dry land, and to analyze the potential of sorghum as biofuels. This research was carried out in low land, on vertisol soil, from August to November 2020. We applied a completely randomized block design with one factor and 3 replications. Seven sorghum varieties were identified namely Numbu, Super 1, Suri 3, Keller, Kawali, Black Sorghum, and Bioguma-2. The results showed that each variety had different genetical properties leading to various growth rates in both vegetative and generative phases. Our finding revealed that Keller variety was the most productive sorghum plant as it produced the highest sugar content (20°Brix). Also, Keller was the tallest plants (>300 cm) compared to other varieties. Bioguma-2 was the second, which was proven by its longest stem (307 cm) and high stem sap content (18°Brix). Thus, we recommended the Keller and Bioguma-2 as the suitable sorghum variety to be utilized in biofuels manufacturing.

<p>ABSTRACT<br />The level of sugarcane yield in dry land or rainfed generally still low at 40 to 50 tons per hectare. Farmers prefer maintenance of sugarcane than unloading ratoon cane (RC). This can be understood because unloading RC requires high cost, especially in the purchase of seed cane and tillage. Approach through maintaining ratoon techniques are expected to increase production and sugar yield. The research purposes to obtain cane yield and sugar yield RC optimally with maintaining ratoon techniques in dry land. Research has conducted in the Ngimbang, Lamongan district from June 2013 until August 2014. Sugarcane varieties used PS 862 (early ripening) belong to farmers. The study compiled by randomized block design (RBD) and repeated 3 times. The treatment consisted of 1). Replanting; 2). Off barring; 3). Organic fertilizer; 4). Maintaining 10 plants/m; 5). Giving PGR; 6). The package of (1+2); 7). The package of (1+2+3); 8). The package of (1+2+3+4); 9). The package of (1+2+3+4+5); and 10). Control. The results showed that the complete treatment of maintaining ratoon (replanting, off barring, organic fertilizer, maintaining 10 plants/m and PGR) obtained the highest value on the highgrowth parameters include 304.67 cm and a diameter of 3.16 cm, while the production parameters include the stalk number 5.73 stalk/m, stalk weight 1.29 kg/stalk, and stalk length 264.11 cm. Maintaining ratoon could gave the best cane yield and sugar yield than ratoon plants without maintaining ratoon cane with an increase of cane yield 16.20 tons/ha (32.14%) and an increase of sugar yield 1.38% (25.60%). Maintaining on ratoon cane 4th on rainfed significantly increase the production of sugarcane per hectare although not linear with increasing sugar yield.<br />Keywords: Maintaining ratoon, PS 862 varieties, dry land, Sacharrum officinarum</p><p> </p><p>PENINGKATAN PRODUKSI DAN RENDEMEN TEBU (Sacharrum officinarum) MELALUI RAWAT RATOON</p><p>ABSTRAK<br />Tingkat produktivitas tebu di lahan kering atau tadah hujan umumnya masih rendah sebesar 40 sampai dengan 50 ton per hektar. Para petani tebu lebih memilih rawat ratoon daripada membongkar tebu ratoon (RC). Hal tersebut dapat dipahami karena membongkar ratoon membutuhkan biaya yang lebih besar, terutama dalam pembelian bibit tebu dan olah tanah. Pendekatan melalui teknik rawat ratoon diharapkan dapat meningkatkan produksi dan rendemen tebu. Tujuan dari penelitian untuk memperoleh pertanaman tebu dengan teknik rawat ratoon yang berproduksi dan berendemen optimal di lahan kering. Penelitian dilaksanakan di Ngimbang, Kabupaten Lamongan mulai Juni 2013 sampai Agustus 2014. Varietas tebu yang digunakan yaitu PS 862 (masak awal) milik petani. Penelitian disusun dengan Rancangan Acak Kelompok (RAK) yang diulang 3 kali. Perlakuan terdiri atas 1). Sulam; 2). Pedot Oyot; 3). Pupuk Organik; 4). Pertahankan 10 tanaman/m; 5). Pemberian ZPT; 6). Paket (1+2); 7). Paket (1+2+3); 8). Paket (1+2+3+4); 9). Paket (1+2+3+4+5); dan 10). Kontrol. Hasil penelitian menunjukkan bahwa perlakuan lengkap pada rawat ratoon (sulam, pedot oyot, pupuk organik, 10 tanaman/m dan ZPT) diperoleh nilai tertinggi pada parameter pertumbuhan meliputi tinggi 304,67 cm dan diameter 3,16 cm, sedangkan parameter produksi meliputi jumlah batang terpanen 5,73 batang/m, bobot batang 1,29 kg/batang, dan panjang batang 264,11 cm. Rawat ratoon dapat memberikan hasil produksi dan rendemen terbaik dibandingkan tanaman tebu tanpa rawat ratoon dengan kenaikan sebesar 16,20 ton/ha (32,14%) dan peningkatan angka rendemen 1,38% (25,60%). Rawat ratoon RC 4 pada lahan tadah hujan secara signifikan meningkatkan produksi tebu perhektar meskipun tidak linier dengan peningkatan rendemen gula.</p><p>Kata kunci: Rawat ratoon, varietas PS 862, lahan kering, Sacharrum officinarum</p>

Sugarcane (Saccharum officinarum L.) play an important role for sugar consumption in Indonesia. Problem found with sugar industry in Indonesia is the low productivity of sugarcane because of cultivation techniques caused by low soil fertility. This research aimed to determine effect of Plant Growth Promoting Rhizobacteria (PGPR) and vermicompost in increasing the growth of sugarcane. The research method used Randomized Block Design (RBD) consisted of 2 factors with a combination of 6 treatments. The first factor was A1 = without PGPR A2 = PGPR (10 ml.L-1) and the second factor was P1 = 3.5 t.ha-1 (50% vermicompost recommended fertilizer), P2 = 7.t ha-1 (100% vermicompost recommended fertilizer) and P3 = 10.5 t.ha-1 (150% vermicompost recommended fertilizer). Variables of this observation are plant height, number of tillers, number of stems, number of internodes, stem diameter, brix value and the yield of sugarcane. At the age 7 months after planting, the treatment of PGPR application at a vermicompost dose of 7 t.ha-1 (78.46 t.ha-1) was able to reduce the need for a vermicompost dose which was shown by a higher yield value compared to without PGPR application with vermicompost 3.5 t.ha-1 and vermicompost dose of 7 t.ha-1. A higher stem weight obtained in the PGPR treatment when compared to the treatment without PGPR. At a vermicompost 7 t.ha-1 and a vermicompost 10.5 t.ha-1 showed a higher stem weight compared to vermicompost 3.5 t.ha-1.

Increased productivity of sugarcane in upland area can be done through the implementation of the integration of manure with a high dose of inorganic fertilizer in the double rows and twice plant populations of single row (“double rows double seeds”) planting arrangement. Limited availability of manure and inorganic fertilizer entails the replacement of manure with green manure fertilizer. The research was aimed to obtain a green manure as replacement manure that can be intercropped in the double rows double seeds planting arrangement. The experiment was done in the Asembagus Experimental Station, Situbondo, East Java on January to December 2014 for plant cane (PC) and from January to December 2015 for ratoon cane (RC). Treatments were arranged in a Randomized Block Design time for replication. The treatment includes (1) the four rows of Crotalaria juncea, (2) two rows of Crotalaria juncea, (3) four rows of peanuts in width between rows of sugar cane, (4) manure, and (5) no organic fertilizer. The results showed that the integration of organic fertilizer with a low dose of inorganic fertilizers increases productivity and sugar yield 5.20 to 41.78% and 33.33 to 69.90%, respectively in PC and 7.33 to 32.67% and 5.74 to 29.61%, respectively in RC from no organic fertilizer. Four rows of Crotalaria juncea could replace the role of manure in improving the productivity and sugar yield for PC and two rows of Crotalaria juncea for RC.
