Abstract

ABSTRACTShallot is a primary commodity with high economic value. However, the productivity of shallot is still low due to the competition with nutgrass. Nutgrass reduces the productivity of shallot down to 50 - 80%. This study aimed to analyze the impact of nutgrass population towards the growth and productivity of shallot, particularly the Super Phillip and Bauji varieties. This study also aimed to find the most adaptable shallot variety in regards to the combination of nutgrass in Wayamiya Village of East Bacan District in South Halmahera Regency from January to March 2020. The methods used in this study were Randomized Complete Block Design (RCBD) in a factorial pattern consisting of two factors and Replacement Series Methods. The latter was used to analyze the interaction of these two plant species and the combination of both. The variables observed include the height of the plant (cm), the number of seedlings, the weight of fresh bulb (g), the air-dried weight (g), the dry weight without stover (g), the average diameter of air-dried bulb (cm), the fresh weight of nutgrass (g), the dried weight of nutgrass (g), and the numbers of nutgrass bulbs per cluster and plot. Based on the variance analysis calculations, the population of nutgrass had a real impact on produced shallots, particularly in terms of height (cm), weight of fresh bulb per plot, weight of dried bulb per plot, weight of dried bulb without stover, and diameter of bulb per plot. The relative yield total (RYT) and Relative Crowding Coefficient were used to examine the occurrence of competition between the two plants. The result of this study revealed the production of dried super phillip bulb without the presence of nutgrass was 9,5 tons/hectare. Meanwhile, with the presence of 4 nutgrass (T1), 8 nutgrass (T2), and 12 nutgrass (T3), the average weight of dried super phillip bulb was 6 tons/hectare. This showed a decrease of 3 tons/hectare or around 30%/hectare. Moreover, in regards to dried bauji bulb without the presence of nutgrass, the production was 9.3 tons/hectare. With the presence of 4 nutgrass (T1), 8 nutgrass (T2), and 12 nutgrass (T3), the dried bauji bulb production decreased to 3.3 tons/hectare or around 60%/hectare. There was a negative interaction between bauji shallots with 10% of nutgrass treatment in the planting. In this case, the RYT value was 1. The Relative Crowding Coefficient value of super phillip shallots with 10%, 20%, and 30% of nutgrass populations was more than one. This indicated the super phillip variety was adaptable with the presence of nutgrass. Meanwhile, the Relative Crowding Coefficient value of bauji shallots was below one.Keywords: : Nutgrass, Shallot, Competition

Abstract

East Halmahera is the main area for developing rice and beef cattle in the North Maluku region. The cultivation of food crops and livestock production generates substantial waste which requires proper management. Precise waste management can reduce environmental pollution in agricultural areas while creating added value opportunities. Rice waste is used with cow manure to produce biogas and organic fertilizer through anaerobic digestion technology. In this research, rice waste and cow dung were used to produce biogas and organic fertilizer through anaerobic digestion. The research is a continuation of previous studies on biogas production in a laboratory setting. The study is divided into two stages: firstly, the production of biogas, and secondly, the creation of organic fertilizer from the remaining bioslurry. The performance of a Modified Profile Anaerobic Reactor biogas digester was evaluated using standard parameters such as pH, temperature, total solids, and flame duration. The nutrient content of the organic fertilizer was tested based on various parameters, including C-organic, Nitrogen (N), C/N ratio, Phosphorus (P2O5), and Potassium (K2O). The results of the research showed that a biogas reactor with a capacity of 2.200 kg produced 4.2 kg of biogas with a flame duration of 12 hours, 7 minutes, and 10 seconds. The average temperature during the process was 29°C, and the total solid organic material decomposition was 33%. Total solid processed organic fertilizer with a C/N value of 16.53, C-Organic content of 24.16%, macronutrients N 1.93%, P2O5 0.37%, and K2O of 1.75%.Keywords: biogas, organic fertilizer, rice husks, cow dung, and East Halmahera.

Abstract

This study aims to examine the concentration of Eco-enzymes based on local Ternate resources in dealing with the greed of Tutman Kailan which was carried out in the Tabam sub-district, North Ternate district. The study used a factorial completely randomized completely randomized design (CRD) with two factors as the main factors. Concentration of top taluk ecoenzyme Eight concentrations of top taluk taluk without concentration (R0) to 7 ml/l water (R7) and lead factor. Kailan seed variety that talukat consists of two varieties, namely the Daily Fram variety and the red arrow variety. The tools used in this study were digital scales, ruler, caliper, spoon, 5 kg polybag, digital camera, sack, label, stationery, paper, hoe. The materials used in the research were soil media, kailan seed, Eco-enzyme. The research was carried out in several stages, namely the manufacture of eco enzymes, preparation of planting media, planting, and data collection. The results showed that the concentration of eco-enzyme based on local resources in Ternate did not have an interaction effect but gave a singular effect, a concentration of 5 ml/l water (R5) resulted in the highest plant height of 34 cm and the number of leaves 7.67 while in leaf area, 2006, 85 cm at a concentration of (R7) 7ml/water but not different from R5. Variable stem diameter Plant fresh weight and root dry weight had no significant effect, while the total fresh weight of treatment R5 gave the highest fresh weight of 280 g in the red arrow variety (V2) as well as the total dry weight of 23.37 g in treatment R5 but the difference variety has no effect.Keywords: Concentration of eco enzyme, local resources, kailan plant

Abstract

ABSTRACTThe main objectives of the present study were to identify the potency to develop the Duku Bacan commodity and to formulate the development strategy of the Duku Bacan Cultivation in the Amasing village of South Halmahera Regency. The samples were collected from 51 Duku growersusing the Purposive Random Sampling method. The data were then analyzed descriptively and quantitatively. The quantitative statistical analyses include the analysis of potency (the density index of Duku Bacan trees, the plant productivity of Duku Bacan, and the potency analysis of Duku Bacan plant), Location Quotient (LQ) analysis, and trading margin analysis. Meanwhile, the qualitative analyses consist of the analyses of land suitability, institutional system, and marketing system of Duku. The SWOT analysis was applied to formulate the development strategy, whilst the priority of the development strategy for Duku Bacan was analyzed using the Analytical Hierarchy Process (AHP) model. The findings revealed that the age of Duku growers was classified into the productive age group with the average educational background level was elementary-school. The traditional farming system was predominantly applied by the growers with low or the absence of a technology input. The potency of Duku Bacan plants in Amasing Kali Village of South Halmahera Regency was identified from the yield that reached up to 2,381 tonnes/hectare with the potency of 176,2 Kg per year. The LQ 1 means that Duku Bacan plant is considered the priority local commodity. The lands in Amasing Kali village are suitable for growing Duku and there are 2 (two) marketing channels for Duku developed in this village. The development strategy of Duku Bacan cultivation in Amasing Kali village based on the scale of priority include the enhancement of the roles of Local Government, the establishment of farmer group institution, the increase of farmer capacity, the optimization of duties and roles of extension workers, the increase of plant production, the optimization of potential land use, strengthening the agribusiness system of Duku and promotion,  and also the utilization of economic agencies.Keywords: Duku Bacan, potency, strategy, development
