Abstract

The Legin (Leguminosae inoculum) application is a technology by mixing Rhizobium inoculants with soybean seeds at the time of planting. The goal is when the existing soybean seeds of the surrounding Rhizobium japanicum bacteria will be symbiotic with the soybean roots. The Rhizobium japanicum bacteria can be isolated from effective symbiotic soybean root nodules, then cultured and can be used as inoculants mixed with peat soil. While cutting shoots done by breaking the apical dominance so that pruning effect on plant growth with the aim of encouraging plants to branch off much and produce new shoots, so as to obtain maximum results. This study examines the application of legin and shoot cutting technology on soybean cultivation. Soybean varieties used are varieties of anjasmara. The results of this study indicate that the application of legin and shoot can increase the production of 1.74 tons / ha.

Abstract

The Government of Indonesia (GOI) has been developing agricultural sector to double the production of rice as the main staple food. By intensifying paddy production through jajar legowo planting system, the GOI has been able to increase paddy production and farmers welfare. This study was conducted in Sedayu Sub District from August to October 2017. The aims of this study were 1) to identify the productivity of paddy tegel planting system and paddy jajar legowo (2:1) planting system; and 2) to determine farmers income of paddy tegel planting system and paddy jajar legowo (2:1) planting system. This study implemented descriptive quantitative research. The participants were selected through purposive sampling. The participants were drawn from the population of Argorejo Farmer Group Association (Gapoktan) in Sedayu Sub District. The results show that the productivity of paddy jajar legowo (2:1) planting system was higher (9,04 tonnes/ha) compared to paddy tegel planting system (7,74 tonnes/ha). In addition, farmers net-income from paddy jajar legowo (2:1) planting system was also higher (Rp 30.012.395,83/ha) than paddy tegel planting system (Rp 22.400.344,05/ha). The results of this study can be used to convince farmers in employing the paddy jajar legowo (2:1) planting system rather than the tegel planting system.

Abstract

The aim of this study was to determine the effect of adding flour of tofu solid waste to nutritional value and organoleptic quality of geblek. The study used a complete randomized design with three replications. The factors studied were the concentration of the addition of flour of tofu solid waste with variations 0%, 2%, 4% and 6%. The parameters observed were moisture content, protein content, fat content, carbohydrate content, phytic acid content, crude fibber content and organoleptic quality of raw and cooked geblek. The results showed that the addition of flour of tofu solid waste will affect the nutritional content of geblek, especially its protein content. Addition of flour of tofu solid waste did not significantly influence phytic acid content in cooked geblek while in raw geblek, increased phytic acid significantly occurred in addition of 6% flour of tofu solid waste. Based on the organoleptic test, the panellists favoured raw and cooked geblek with the addition of 2% flour of tofu solid waste whereas raw geblek had water content of 46.59 0.32%, ash content 0.59 0.06%, protein content 0.61 0,00%, carbohydrate content 52,21 0,26%, and phytic acid content 0,009 0,00% while cooked geblek have moisture content 27,20 1,41%, ash content 1,59 0,06 %, protein content 0,72 0,00%, fat content 10,42 0,05%, carbohydrate content 60,08 1,42%, crude fibber content 0,93 0,12%, and phytic acid content 0.018 0.01%.
