Abstract

Research on the integrated control of Crocidolomia pavonana on cabbage aims to test various cabbage cultivation techniques, namely the use of organic fertilizers, botanical insecticides, and multiple croping. This research was conducted in Paslaten Sub-District, Tomohon City, from January 2011 to January 2012. The parameters observed included the percentage of attacks, cabbage production, profit analysis of organic and non- organic cultivation, measurement of climate parameters, analysis of total soil N content, total N content of fertilizer organic foliage and chicken manure. This experiment used a randomized block design (RBD) with orthogonal contrast with eleven (11) treatments and four (4) replications. The results showed that the highest attack percentage at 6 mst was found in mitraflora + B. asiatica fertilizer treatment 12.5% chicken manure + B. asiatica 7.14%, farmer habit patterns 5.36%, and campus organic fertilizer treatment + B asiatica 1.79%. The highest percentage of attacks at 8 mst was found in the treatment of mitraflora + B. asiatica fertilizer 37.5%, chicken manure + B. asiatica 26.79%, campus organic fertilizer + B. asiatica 16.07%, farmers' habit patterns 7.14%. The highest attack percentage at 10 mst was found in mitraflora + B. asiatica fertilizer treatment 21.43%, farmer habit pattern treatment 16.07%, chicken manure + B. asiatica 12.5%, campus organic fertilizer + B. asiatica 10, 71%. The highest cabbage production was produced by the treatment of farmers' habit patterns, namely 42.8 kg / plot, followed by the treatment of campus organic fertilizer + B. asiatica with a production rate of 34.6 kg / plot, treatment of chicken manure + B. asiatica 29.5 kg / plot, fertilizer treatment mitraflora + B. asiatica 27.8 kg / plot.

Abstract

Tailing is a type of waste produced by mining activities and is characterized by very low physical, chemical, and biological fertility, requiring efforts to amend its quality. The addition of organic materials as a soil ameliorant is one such effort of amendment to enhance success in rehabilitating these degraded areas. The aim of this study is to measure the effects of ameliorant on the growth and yield of sweet corn, determine dosage that will give the best growth and yield, and find out if residual mercury exists in the resultant sweet corn crop. This study used a randomized block design with 6 treatments: A= 40 tons/ha of organic fertilizer; B2= 50 tons/ha of organic fertilizer, C = 60 tons/ha of organic fertilizer, D = 40 tons/ha of organic+ fertilizer, E = 50 tons/ha of organic+ fertilizer, F = 60 ton/ha of organic+ fertilizer. The organic fertilizer used was a mix of 50% water hyacinth + 50% chicken manure, while organic+ fertilizer was a mix of 20% water hyacinth + 20% cow manure + 20% chicken manure + 20% traditional market waste + 20% rice straw. Every treatment was replicated four times, resulting in 24 experimental pots. Variables observed were: 1) cob length, 2) cob diameter, 3) cob weight. Data was analyzed using ANOVA and Tukey’s HSD at a test level of 5%. Results show that organic+ fertilizer increases the yield of sweet corn. A dosage of 60 tons/ha gave the best cobs with a weight of 199,89 grams per cob.

Abstract

Chili is a strategic commodity with important economic value in Indonesia. The Ministry of Agriculture included chili in a special program as of 2015 to increase production. Chili as a commodity has a high impact on Indonesia’s economy, party because fluctuations in its price can influence inflation. Data from the Central Statistics Agency indicate that chili supplies decrease during the rainy season while demand increases in the months of Ramadhan, Christmas, and New Year, and in these times chili prices increase and cause inflation. To support national demand, there needs to be an increase in chili productivity. Chili plots sometimes cannot be planted year-round due to the high use of artificial chemical fertilizer with excessive dosage, thus decreasing the quality of land and quality and volume of chili crop yield. For that reason, there needs to be a study that identifies cultivation techniques for chili in the regency of Southeast Minahasa. Study results show that cultivation methods in Molompar village, Southeast Minahasa, still depends on farmers’ experiences. Field instructors have not been optimally guiding the local farmers.

Abstract

Current post-harvest procedures for food crops are lacking, mostly due to the shortage of adequate postharvest facilities and technology, outdated knowledge and skills of the farmers, and lack of awareness of more modern post-harvest handling. Furthermore, farmers have yet to understand and experience the benefits of post-harvest procedures that can increase crop quality. Harvest and post-harvest procedures for food crops are a strategic step in supporting national food security. Post-harvest procedures directly decrease losses, maintain quality, and increase farmer profits and competitiveness. Surveys by Statistics Indonesia (2012) showed that the national conversion rates of Harvested Dry Grain to Milled Dry Grain are 83,26%, while national conversion rates of Milled Dry Grain to rice are 62,47%. This illustrates a national loss potential throughout the conversion chain, estimated to be 40 billion Rupiahs every year. Efforts to improve harvest and post-harvest procedures for foor crops (with good technological support) need to be targeted towards three things (1) reduction of loss; (2) increase of quality and competitiveness (standardize processes and yield quality); (3) increase of farmer welfare. For this reason, the participation of all postharvest stakeholders is required in standardizing the process and yield quality in post-harvest processes.

Abstract

Clove (Syzigium aromaticum L.) is one of the important commodity crop farming, especially as a basic material in the kretek cigarette industry, also belong to the volatile oil-producing spice crops used as basic materials for pharmaceutical and food industries. The study aims were: 1) manipulating the canopy shape of clove plants to be shorter than normal, (2) obtaining the right dose to increase the productivity of young clove plants. Benefit study is to provide information technology for the farmers to increase crop productivity clove.  Research was done in the  Popareng Village,  District of Tatapaan, South Minahasa Regency in November 2011 to May 2012. Research compiled in Randomized Block Design (RBD) with one factor of treatment, consisting of four dosage of paclobutrazol (P), namely: P0 = 0 g tree-1; P1 = 1.0 g tree-1; P2 = 1.5 g tree-1 : P3 = 2.0 g  tree-1. The results showed that paclobutrazol inhibited the high growth of the apical buds is 72% at a dosage of 1.0 g tree-1, 73% at a dosage of 1.5 g tree-1 and 81% at a dosage of 2.0 g tree-1 that produces clove crop 3-year-old to be shorter than normal growth. Paclobutrazol applications increase weight 1000 grain dried flowers tree-1 and production tree-1. Highest production achieved in the paclobutrazol dosage 2.0 g tree-1, which is  0.024 kg of 1000 grain weight of dried flowers and production  tree-1 is 3.350 kg, while the lowest production in a dosage of 0.0 g paclobutrazol (control), is 0.192 kg of 1000 grain weight dried flowers and production tree-1  is 1.012 kg.

Abstract

This research aims to discover the effects of Gibberellin, Kinetin, IAA, and Paclobutrazol growth regulators towards the growth and yield of suluttan unsrat 1 (SU1) and suluttan unsrat 2 (SU2) rice varieties. This research was done using split plots design with SU1 and SU2 varieties being the main plots and the subplots: Z0 (without plant growth regulator (PGR)); ZK (kinetin treatment); ZG (Giberellin treatment); ZI(IAA treatment); ZP (Paclobutrazol treatment).  Each plot was replicated four times. Results show that there is no interaction between varieties and PGR treatment in temrs of growth variables, yield variables, and yield of SU1 and SU2. Gibberellin spray treatment in the beginning of reproductive stage increased plant height during harvest phase and length of rice panicle, but not increase grains per panicle. Individual treatments of IAA, Kinetin, Paclobutrazol growth regulators did not affect growth, yield, of SU1 and SU2. The timing, dosage, and frequency of PGR applications maybe was not yet optimal and did not increase the yield of SU1 and SU2 varieties.
