Abstract

Organonitrofos is one type of organic fertilizer capable of providing macro nutrients that more than other organic fertilizers, particularly nitrogen and phosphorous from the compost of a mixture of fresh manure and rock phosphate using Microbial N2-fixer and P-solubilizer. Research purpose was to study the effect of organonitrophos combined with inorganic fertilizer on the growth, production, yield of sugarcane, and determining the most effective combination of agronomically and economically in up landsugarcane. Research consisted of 5 treatments with 3 replications arranged in a randomized complete block design. The treatment were A (300 kg ha-1 Urea, 150 kg ha-1 TSP, 300 kg ha-1 KCl), B (300 kg ha-1 Urea, 150 kg ha-1 TSP, 300 kg ha-1 KCl, 5,000 kg ha-1 Organonitrophos), C (150 kg ha-1 Urea, 75 kg ha-1 TSP, 150 kg ha-1 KCl, 10,000 kg ha-1 Organonitrophos), D (10,000 kg ha-1 Organonitrophos), and E (without fertilization). The results showed that the dose of fertilizer recommendation (300 kg ha-1 urea, 150 kg ha-1 TSP, 300 kg ha-1 KCl) supplemented with 5 ton ha-1 Organonitrofos compared to the doses of fertilizer recommendation (300 kg ha-1 Urea, 150 TSP kg ha-1, 300 kg ha-1 KCl) was not significantly different on growth, yield, productivity of sugarcane and sugar. While the addition of 10 ton ha-1 Organonitrofos at half dose of recommendation (150 kg ha-1 urea, 75 kg ha-1 TSP, and 150 kg ha-1 KCl) produced 106.11 tons ha-1of sugarcane and 7, 95 ton ha-1sugar being lower than the dose of fertilizer recommendation that produced 133.02 tons ha-1sugarcane and 10.72 ton ha-1 sugar resulting macro nutrients derived from half dose of fertilizer recommendation are not able to increase the productivity of sugarcane and sugar.Dose of fertilizer recommendation plus 5 ton ha-1 Organonitrofos was an effective dose of fertilizer agronomically while fertilizer dosage recommendation was the most efficient dose of fertilizer economically.Keywords :dry land, fertilizer, inorganic, Organonitrophos, sugar cane

Abstract

Inerie Ngada variety of red bean plants in East Nusa Tenggara is generally cultivated on a plateau which  breadth is very limited, eventhough the lowland in NTT with dry climate and  agro-climate conditions is very wide. Due to the limited extent of the existing highlands, the efforts to develop red bean plants in the lowlands need to be done. However, the development of this plant is constrained by the altitude of the place in accordance with the growth of red beans. Differences in the height of the place may affect the climate difference, temperature, humidity and light intensity. Therefore, it is necessary to use technology that can modify the microclimate of plants, one of which is the use of biochar followed by adjusting the volume of watering. Seeds are one of the key successes of farming. The use of quality seeds can increase the production of plants including Inerie Ngada variety of red beans. This study aims to determine the effect of the type of biochar and the volume of water supply on red bean seed production of Inerie variety in lowland with dry climate. The research employed a complete randomized design of biochar factorial factor. The types of biochar were  B: B1: rice husk of ranga, B2: wood charcoal, B3: coconut shell charcoal, and B4: sawdust charcoal and water volume (A) factor: A1: 100% of ETc; A2: 85% of ETc; A3: 70% of  ETc; A4: 55% of ETc and A5: 40% of ETc. The results of the study showed that there was an interaction between type of biochar and volume of water towards the total of  pod content, number of seeds and weight of Ngada Inerie of  red beans per plant. The coconut shell charcoal of biochar treatment with 85% Etc of the water supply volume gave the best effect on red bean seeds with total pod content (12,585 pods), number of seeds (32,833 eggs), seed weight (9,493 gr), and seed  weight of 100 (31,065 g). Hence,  the production of Inerie Ngada of red bean seeds  can be developed in dry lowland by using the technology of coconut shell charcoal biochar followed by 85% of Etc of water supply volume.

Abstract

Resistant starch is a starch fraction that can not be hydrolyzed by digestive enzymes in the small intestine and classified as a prebiotic compound. Increasing the content of resistant starch to a certain amount in Siger Rice (modified tiwul) will decrease the cooking quality. The objective of this research was to study the relationship between resistant starch content and cooking quality of Siger Rice (eating quality, texture, and taste). The increase of resistant starch content in siger rice was done by the application of autoclaving-cooling cycling treatment, through steam stages, cooling to room temperature, followed by cooling at 4°C for 0 hours/control, 12 hours, 24 hours, 36 hours and 48 hours. The results showed that the increase of resistant starch content ≤ 10% (9.85%) will improve the quality characteristics of Siger Rice for all organoleptic scores, i.e., eating quality (7,15 to 8,2), texture (7.05 to 8.35), and flavor (6.95 to 8.15); on the contrary, the increase of resistant starch content more than 10% (14.25%) will decrease the cooking quality characteristics of Siger Rice for all organoleptic scores, i.e., eating quality (7.15 to 6.8), texture (7.05 to 6.6), and taste (6.95 to 6.4).

Abstract

The largest food commodity in Indonesia is rice (Oryza sativa), because rice is the main food source for most of Indonesia's population. Rice productivity can be increased, among others through innovation of high yield rice varieties, resistant to biotic and abiotic stress, and have good rice quality. The effort to form high yielding high yielding varieties requires several stages, one of which is power yield test. This research was conducted to obtain potential yield data from the four strains tested in the fourth generation. The strains studied were MS1, MS2, MS3 and ChM strains, with two varieties of varieties, namely Ciherang and Cilamaya varieties. This study used per-line planting method and conducted with Randomize Completly Block Design (RCBD).  Observations were made on selected individual plants as samples. The variables observed were maximum plant height, maximum number of shoots, number of productive shoots, flowering age, harvest age, panicle length, number of grain per panicle, amount of unhulled grain per panicle, total grain per panicle, weight 1,000 grains, Clumps and grain yield per hectare. The data were analyzed by using variance, and if there was any difference between treatments, then the data will be tested further with Least Significant Different (LSD) on stage 5%.. Based on the observation and test, the result of production of each strain is MS1 strain of 7.24 ton.ha-1, MS2 strain of 6.06 ton.ha-1, MS3 strain of 6.29 ton.ha-1, and ChM strain of 6.01 ton.ha-1.
