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procedures for food crops are lacking, mostly due to the shortage of adequate postharvest facilities and technology, outdated knowledge and skills of the farmers, and lack of awareness of more modern post-harvest handling.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.

Abstract

The purpose of this research was to obtain the interaction between the dose of cow manure and the type of local microorganism (MOL) in increasing soybean growth, to obtain the dose of cow manure and the dose of MOL that gave the best growth of soybean plants. The two-factor factorial study used a completely randomized design. The treatment consisted of, Factor I (A) = Dosage of Cow Manure. A1 = 10 tons/ha, A2 = 20 tons/ha, A3 = 30 tons/ha. Factor II (B) = Type of Local Microorganisms (MOL). Bo = No MOL; B1 = MOL Banana hump (5 liters/ha); B2 = MOL Papaya (5 liters/ha), B3 = MOL Rice (5 liters/ha). Each treatment was repeated three times to obtain 36 experimental pots. The variables observed were: plant height and number of leaves as primary data and N, P, K content in each MOL as secondary data). Primary data were analyzed using analysis of variance and if there was a difference, it was continued with the Least Significant Difference Test (BNT) at the 5% test level. The results showed that the interaction between cow manure and various types of MOL significantly affected plant height and number of soybean leaves. 20 tons of cow manure on MOL banana weevil increased the growth of plant height and number of soybean leaves.

Abstract

Indonesia is the second largest vanilla producer in the world. Vanillin produced from the drying process of vanilla fruit is the second most valuable commodity in the food and beverage industry in the world. The main obstacle for vanilla cultivation in Indonesia is the attack of vanilla stem rot (BBV). The cause of disease (pathogen) BBV in Indonesia is Fusarium oxysporum f.sp. vanillae. Therefore, it is very important to obtain information about the population of the pathogen Fusarium oxysporum f.sp. vanillae to support the successful assembly of vanilla varieties that are resistant to Fusarium oxysporum f.sp. vanillae. Currently, information on the diversity of the pathogenic population of Fusarium oxysporum f.sp. vanillae in North Sulawesi Province is unknown. This study reports the diversity of the pathogenic population of Fusarium oxysporum f.sp. vanillae originating from North Sulawesi. Samples of stem rot were taken from several villages in Minahasa and Southeast Minahasa and South Minahasa districts. The stem rot samples were taken to the laboratory for isolation and identification. The variation observed was based on the appearance of the isolates on PDA (potato dextrose agar) media. The results showed that the appearance of the isolate Fusarium oxysporum f.sp. vanillae varies based on PDA media.
