Abstract

Brown cane sugar is traditionally produced by small enterprises at DesaBlang Mancung (Ketol District, Aceh Tengah Regency), one of them is Sara Ate Enterpriserun by a group of local young men since 2010. The product is purchased by food industriesin Medan and used as ingredients. However, its price was rather low around Rp. 5000,-per kilogram due to high content solid impurities. In this work, we introduced an improveddesign of solid separation equiment to remove un-dissolved content of the brown canesugar juice. A two stage stainless steel screen was applied to filter solids from the juice.The screen also separated entrained bagasse. The filtrate was then flowed to a settler thatallows further separation of solids such as sand or clay. To minimize possibility ofimpurities entrainment during cooking process, the furnace was also modified by usingconcrete construction. As the result, much better brown cane sugar was produced withmuch lower solid impurities (2.2% w/w) and brighter appearance, thus complying grade IISNI 01-6237-2000 .

Abstract

Analysis of Land Suitability Criteria for Cocoa Production of Three Cluster Development in Pidie DistrictAbstract. Development of cocoa in Pidie District is divided into three clusters, namely Cluster Padang Tiji, Cluster Keumala and Cluster Tangse. This study was aimed at the analysis of land suitability for cocoa in order to understand relationships between characteristics of the land and production and fat content of cocoa and factors that influence it. Method used was a survey method to obtain land characteristics, management and production levels of cocoa. Land Unit Map (LUM) of each cluster was formed by overlapping maps of soil type, slope, and land use. Evaluation of land suitability on each LUM was done by suitability classification method developed by FAO. Relationships between characteristics of land and production and fat levels were analyzed using correlation analysis. Multiple linear analyses were carried out for land characteristics that significantly affect production components and fat content. The results showed that clusters of Keumala and Padang Tiji had actual land suitability classes of marginal suitable (S3), while Tangse had those of adequately suitable (S2) and marginal suitable (S3). Potential land suitability classes of Padang Tiji cluster was S3, while clusters of Keumala and Tangse were S2 and S3. Results of multiple linear regression analyses showed that there was a very close relationship (R2=0.95) between characteristics of land and production, while a close relationship (R2=0.64) between characteristics of the land and fat content. Determinants of production were altitude, slope, sand fraction, clay fraction, pH H2O, pH KCl, organic C, total N, available P, Na, Al saturation, cation exchange capacity, base saturation and salinity, while determinants of fat content were altitude, organic C, total N, available P, Ca, and Mg.Abstrak.

Abstract

Indonesia is one of the cocoa producing countries in the world. Although the amount of cocoa production and planted area has increased, the quality of cocoa beans in Indonesia including Aceh is still low. This happened because the farmers did not carry out the fermentation process. Fermentation is one of the most important steps that must be taken to improve cocoa quality. However, it is rarely done because it takes a long time. The purpose of this study was to analyze the use of starter bacteria lactic acid (LAB) and acetic acid (BAA) indigenous Aceh cocoa in fermenting Aceh cocoa. The research was conducted by fermenting cocoa with two different factors, namely the type of starter (control, LAB, BAA, LAB-BAA mixture) and fermentation time (3,4 and 5 days). The results showed that the use of Acehnese cocoa indigenus bacteria starter and different fermentation time had an effect on fermentation conditions and the quality of fermented cocoa beans. Fermentation of cocoa beans with the addition of a dry starter affects the pH value and the percentage of fermented cocoa beans. The best treatment was obtained when using LAB starter with fermentation time of 4 days, with the same fermented quality of cocoa beans with fermentation using LAB and BAA for 5 days of fermentation. Further research is needed to confirm the quality of fermented cocoa beans produced by analyzing volatile chemical components and flavors.

ABSTRACT. Improvement of production and quality of cocoa can be done through the implementation of appropriate technology adoption and implementation of good cultivation techniques in the field of cocoa farmers. Implementation of pruning, composting, composting with different treatment doses will produce a diverse production. This study aimed to analyze the implementation of the adoption of cultivation techniques performed by cocoa farmers in Pidie district. The research location in District Mila and Padang Tijie, with samples of cocoa farmers and land farmers. The samples were conducted by purposive sampling with descriptive analysis model to examine the application of technology and cultivation techniques. Randomized block design was used to examine the use of compost and trimming of various treatments.The results showed that the application of integrated technologies in cocoa cultivation but not perfectly executed. The absence of treatment replications resulted in farmers forget. Cocoa with a dose of compost 9 kg / plant, has the effect of the dry weight of the cocoa beans tend to be greater in the treatment done trimming. A combination of composting 13.5 kg / plant by pruning showed the highest average at the variable total weight of dried fruit and cocoa beans. Organic fertilizers 15 tons/ha yield the best cocoa.

Abstract

Due to increasing demand of petroleum and limited source of fossil fuel, it isneeded to explore and find source of a renewable energy. The biomass from agricultural residues, forest and farm waste has been known as a great source of energy and can be converted into biogas, bioethanol, biodiesel, etc. Reed which is abundant in Indonesia is one of potential sources of lignocellulose biomass that can be utilized as (Imperata cylindrica) a source of renewable energy such as bioethanol. The aim of this study was to optimize yield of glucose from reed using cellulose enzyme. Factors used in this research werepH and substrate particle size. Reed particle sizes were 80 and 100 mesh and pH of the solution were 4.2, 4.8 and 5.5. The results showedthat dried reedwith100 meshes in particle size which hydrolysed in enzyme solution with pH 5.5 at 37oC for 72 hours, producedthe highest yield of glucose in the amount of 80.2 mg/ml (8.02 %). When the incubation time was extended, glucose yield increased to 121.8 mg/ml (12.1%) at 96 hours and then decreased as the incubation time was extended further

Abstract

Coffee (Coffea sp) is one of the most popular drinks in Indonesia, as well as in the world. Coffee plantation has been grown in several areas in Indonesia, including Aceh province, and has become one of the most important plantation products with promising economic value. Both Arabica and Robusta are found in Aceh, however Arabica coffee grown more in the area because of its popularity in International market. This popularity is related to Arabica coffee distinctive flavor and aroma. To grow well, Arabica coffee requires land with altitude 1000 m or more above sea level. Therefore, in Aceh, it is grown in the Gayo Plateau with total area more than 90.000 hectares.  As International market requires higher standard coffee, there is a need to provide a better quality coffee with a better taste, flavor and aroma.  Several coffee varieties have been cultivated in the area for a long time, however the relation between variety and taste flavor has not been fully investigated. Other factors that may affect the taste, flavor and aroma is processing technique applied during postharvest and handling. Both wet hulling and dry hulling are practiced by small holders and farmers in the area. This study is aimed to investigate taste and flavor of Arabica coffee as affected by varieties and processing technique. The already grown varieties used in this study were Ateng Super (V1), Bergendal (V2), Bor-Bor (V3), Tim-Tim (V4) and Lini_S (V5). The processing techniques to be considered were Dry Hulling (TA) and Wet Hulling (TB). Observations to be recorded were organoleptic test (fragrance, acidity, body, flavor, aftertaste, balance), pH analysis and caffeine content. The result shows that the Tim-Tim variety get the highest organoleptic score, while between the two techniques, wet hulling provide a better acceptance from the panelist (get higher organoleptic scores)
