Abstract

Indonesia is a nutmeg exporter with the highest export value during 2012‒2020. However, the growth of Indonesia's export value is lower than its competitors. Therefore, to maintain its position as a major exporter, it is important to know its competitiveness. This study aims to explain the competitiveness of Indonesian nutmeg in the world and in ten export destinations. In addition, this study was conducted to analyze the competitive position in the export destination market. The study uses secondary data from UN Comtrade. The data are Indonesian export values of whole and powdered nutmeg in the international market and in ten destination countries during 2012‒2020. The data were processed using revealed comparative advantage (RCA) and dynamic revealed comparative advantage (DRCA) analysis. The results showed that Indonesian whole and powdered nutmeg were competitive in the world market. However, the competitiveness is lower than nutmeg competitiveness of Sri Lanka. Indonesian nutmegs in ten destination markets are also competitive, with the highest competitiveness being in Italy and Germany. Nevertheless, the always positive growth of competitiveness from two products occurred in Japan, thus make Japan's competitive position in rising star during the period of 2018‒2020. Increasing the competitiveness of nutmeg can be done by increasing the export value of the product through regulations by the government regarding post-harvest handling so that there is only a small amount of aflatoxin. In addition, the government can more focus on increasing exports to Japan. Keywords: competitiveness, dynamic revealed comparative advantage, revealed comparative advantage, nutmeg

Abstract

The balance of ecological and economic utilization plays a real role in maintaining the stability of turtle nesting habitat on the coast. This study aims to calculate the suitability index and visitation carrying capacity (DDK) of sea turtle nesting habitat to maintain the sustainability of its population. The survey was conducted in December 2020 to January 2021 at Batu Kumbang Beach, Pulau Baru Village, Muko-Muko Regency. The analysis used was the Habitat Suitability Index (IKH), Tourism Conformity Index (IKW), and visitation carrying capacity (DDK). The Mukomuko Turtle Conservation Nature Lovers Community (KPAKPM) reported that this beach is still predominantly used as a nesting habitat for green turtles (Chelonia mydas), olive ridley sea turtles (Lepidochelys olivacea), hawksbill turtles (Eretmochelys imbricata), and leatherback turtles (Dermochelys coriacea) in 2018. At least 35 heads of various types landed and laid eggs here and further decreased in 2020 with only 17 heads. The IKH showed that about 84.06%, 75.36%, and 75.36% belonged to the highly appropriate category and were spread out at Stations 1, 2, and 3, respectively. The suitability of the coastal area is at a value of 2.0 ≤ IKW < 2.5, and is categorized as sustainable. The number of visitors allowed according to DDK is only 84 people per day. Batu Kumbang Beach needs to be managed in a balanced manner with a conservation approach and beach ecotourism to ensure the sustainability and sustainability of nesting habitats for various types of turtles. Keywords: beach conservation, ecosystem, turtle nesting habitat

Abstract

Fair Trade (FT) coffee has a higher production volume than other coffee certifications. This phenomenon is triggered by a shift that is influenced consumer behavior patterns. This study analyzes consumer characteristics, purchasing decisions, and satisfaction in buying FT coffee. A cross-sectional study with a quantitative approach was used as the research design. Data were obtained by distributing online questionnaires to 120 respondents using a voluntary sampling technique. Data were analyzed using descriptive analysis, Customer Satisfaction Index (CSI), and Importance Performance Analysis (IPA). The results showed that most respondents were male, with an undergraduate degree and unmarried status. Trends and easy to get drink influence the main reason for purchasing. The main source of information comes from friends who focus on the coffee's taste and flavor. Consumers will continue to buy coffee even though prices have increased. Through CSI calculation, customer satisfaction is worth 74.04%. The results of the IPA calculation show that the main attributes to be improved are price, sales location, and information provision. The results of this study can be used as information on developing a marketing strategy that is adjusted to evaluate consumer expectations. Keywords: characteristics, consumer behavior, fair trade coffee, purchasing decision, satisfaction

Abstract

The scarcity and high cost of high-quality sawn timber has resulted in the switching of furniture industry to using composite wood such as medium density fiberboard (MDF) as the raw material for its products. One of the factors that affect production costs and product quality in the furniture industry is the quality of the cutting tool used in the cutting operation. The quality of the cutting tool could be improved through the addition of coatings on the surface of cutting tool (surface coating). The purpose of this study was to determine the life time of AlCrN, TiAlN, and TiN coated tungsten carbide (TC) tools in cutting MDF. Cutting operations were performed on a computer numerical control (CNC) router machine at feed per revolution (Frev) of 0,10, 0,15, 0,20, and 0,30 mm/rev. The TC cutting tool life was determined based on its wear and was calculated using the Taylor tool life formula. The results showed that coated TC cutting tool provided a better wear resistance and longer life than uncoated TC cutting tool. The low of Frev set in cutting MDF resulted in a lower wear and longer life of cutting tool. AlCrN coated TC cutting tool provided the best wear resistance and longest life, thus it promising to be developed and used in cutting MDF. Keywords: coated cutting tool, medium density fiberboard, surface coating, tool life, wear

Abstract

Edible flower is a flower that is safe for consumption both in fresh and processed form. In fresh form, edible flowers are used as garnishes or food decorations and a unique flavor enhancer. Kenikir (Cosmos sulphureus) is one of the edible flowers that are safe for consumption in fresh form. However, in fresh condition, flowers are easily damaged so that their market share is limited. Coating using aloe vera, which can hold moisture while having antimicrobial properties, is a method to maintain flower freshness. The purpose of the study was to examine the effect of aloe vera coating application to maintain the quality of kenikir as a fresh edible flower. The experimental design used was a two-factor completely randomized design with the first factor being the concentration of aloe vera flour (0.5% and 1%) and the second factor being spray frequency (1 application and 2 applications). Quality parameters measured during storage were respiration rate, weight loss, moisture content, and color. The results showed that the coating with the L2S2 formulation (1% aloe vera flour concentration with 2 applications) was the best treatment with a weight loss value of 7.3%, water content 82.57%, respiration rate 898.99 ml kg-1 hour-1, and has the highest brightness value. Based on these parameters, the L2S2 treatment could maintain the quality of kenikir as fresh edible flowers for up to 5 days compared to the control, which lasted 2 days at 10°C storage temperature. Keywords: aloe vera powder, coat spraying, Cosmos sulphureus, edible flower, kenikir flower

Abstract

The study aimed to determine the effect of lactic acid bacteria, fermentation time, and pressurized heating-cooling cycle on the formation of resistant starch content of beneng taro (Xanthosoma undipes K. Koch) flour. The materials used were beneng corm, isolates of lactic acid bacteria Lactobacillus casei and Streptococcus thermophilus, and MRSB media. The experimental design was randomized block design factorial with two factors: fermentation time (0, 18, and 24 hours) and pressurized-cooling heating (1, 2, and 3- cycles) in 3 replicates. The data were analyzed using analysis of variance and if necessary continued with Duncan's Multiple Range Test at a level of 95%. The tested parameters were the content of resistant starch, amylose, and amylopectin and the data were treated using variance of analysis. The results showed that the combination of L. casei and S. thermophillus produced the highest resistant starch content of 5.66%. Fermentation time of 18 and 24 hours produced resistant starch content of 4.46% and 4.51%, respectively. Autoclaving-cooling of 1-, 2-, and 3-cycle produced a similar type of resistant starch of 3.81%, 4.26%, and 4.16%, respectively. Therefore, the combination of L. casei and S. thermophillus fermented in 18 hours and 1-cycle of autoclaving-cooling is recommended to produce resistant beneng taro flour starch content. Keywords: fermentation, autoclaving-cooling, resistant starch, taro beneng, Xanthosoma undipes K. Koch

Abstract

Under suboptimal conditions, plants generally respond differently to survive. Plant responses include changes in morphology, anatomy, and physiology. This study aimed to investigate the response of eggplant to lack of oxygen due to shallow water table and waterlogging in the generative stage and explored their adaptability to be cultivated in riparian wetlands. This research was conducted from October 2017 to January 2018 in an experimental pond in the village of Demang Lebar Daun Palembang and at the Postgraduate Integrated Laboratory, Faculty of Agriculture, Sriwijaya University, Palembang. This study used a randomized block design with a shallow water table and waterlogging treatments: control (field capacity), water tables of 13 cm, 8 cm, and 3 cm below the soil surface (bss), and waterlogging 2 cm above the soil surface. The results showed that the water table 3 cm bss and waterlogging decreased the relative rate of leaf expansion, specific leaf fresh weight, and specific leaf water content. On the sixth day of the waterlogging treatment, the chlorophyll content decreased by 31.29%. On the other hand, the proline content in the leaves reached the highest level of concentration. After the sixth day, the chlorophyll content increased while the proline content decreased, and the eggplant recovered. Water table 3 cm bss and waterlogging caused the formation of aerenchyma tissue in the roots, which started one day after the treatment. Eggplant is an adaptive crop with a fairly high tolerance for shallow water tables and waterlogging. Keywords: adaptation, aerenchyma, proline, riparian wetland, tolerance

Home garden “pekarangan” plays an important role in conserving plant diversity in urban and suburban area. The suburban area including of pekarangan is a buffer area to preserve the quality of the urban environment. This study aimed to determine the utilization and plant diversity in suburban pekarangan of Yogyakarta. This research was carried out in Maguwoharjo using a survey method for 105 samples of home garden. Data were collected by observation using purposive sampling based on size of yard area. The results showed that the utilization of pekarangan in Maguwoharjo was dominated by ornamental plants, consist of sri rejeki (Aglaonema sp., Araceae), orchids (Dendrobium, Orchidaceae) and frangipani trees (Plumeria sp., Apocynaceae). Other functions of home garden were fruit plant and ground cover/grass. There was found 90 species of plants from 49 families, 27 species of trees, 60 species of shrubs, and three species of ground cover. The Shannon Wienner plant diversity index (H') was above 3 indicating the high category and the Evenness species evenness index (E) was close to 1 indicating a stable ecosystem condition. The H’ and E index based on size of yard area showed 3.74 and 0.88 (very small, <20 m2), 3.90 and 0,.89 (small, 20–50 m2), 3.44 and 0.88 (medium, 50–100 m2), 3.52 and 0.93 (big, 100–200 m2), 3.06 and 0.94 (very big, >200 m2). The results showed that suburban home garden “pekarangan” can support quality of urban ecosystem and its preservation.

Abstract

Cultivation of bell peppers by farmers in Pasirlangu Village, Cisarua District, West Bandung Regency, tends to reach less optimum production, indicated by the average production per crop. The purpose of this study is to evaluate three aspects: (1) factors that affect productivity, (2) allocative efficiency, and (3) income of paprika farming in Pasirlangu Village. The Ordinary Least Squares method was used to analyze factors affecting productivity, the Marginal Product Value method to assess allocative efficiency, and the R/C ratio to calculate cultivation profits. The results showed that labor and seed inputs are inputs that have a significant effect on the productivity of agricultural businesses. In the efficiency analysis, seed input and husk charcoal are not efficient inputs, so these inputs need to be added. The income analysis shows that the paprika farming business in Pasirlangu Village is still profitable even though it is not optimal, as indicated by the ratio of profits and costs, which is > 1. Keywords: bell pepper, income analysis, marginal product value, ordinary least squares, R/C ratio
