Abstract

This study aims to determine the effect of sorbitol concentration and solution volume on the mold on the physical properties of the edible film from sago strach. This research was conducted at the Laboratory of Agricultural Sciences STIP Mujahidin Tolitoli, Tuweley Village, Baolan District, Tolitoli Regency, Central Sulawesi Tengah from October to December 2020. This study used a factorial completely randomized design (FCRD). The first factor (a) is the concentration of sorbitol, namely a1 (5 mL/100 mL solution), a2 (6 mL/100 mL solution), and a3 (7 mL/100 mL solution) while the second factor (m) is the volume of the solution in the mold, namely m1 (5 mL), m2 (10 mL), and m3 (15 mL). The data were analyzed using variance followed by the 1% Duncant Multiple Range Test (DMRT). The results showed that the addition of sorbitol concentration had an effect on the color, thickness, and solubility in water, while the addition of solution volume in the mold affected the color, thickness and water vapor transmission. The best treatment due to the addition of sorbitol concentration to edible film is 5% sorbitol concentration treatment, namely the color has a high brightness level, 0.19 mm thickness, and 41.5% solubility. While the best treatment due to the addition of the volume of the solution on the edible film is the treatment of the 5 ml solution volume, namely the color has a high level of brightness, a thickness of 0.14 mm and a water vapor transmission of 1.11g/m2.hour. Keywords: edible film, sago starch, sorbitol

Abstract

Chrysanthemum cur flowers have many benefits in that they can be used for flower bouquets, pollution absorbers, and even traditional medicinal plants. One of the national chrysanthemum cutting flower centers is in Cianjur Regency, which contributes 53% of total production for West Java Province. Every year, this high production of cut flowers is also followed by higher price differences between the farmer and final seller levels. This study aims to analyze the efficiency of chrysanthemum cut flower marketing in Cianjur Regency. Respondents included farmers, collectors, wholesalers, and florists. Marketing efficiency was analyzed using the composite index method and the Acharya & Aggarwal method, using three indicators: marketing margin, farmer's share, and marketing costs. There are three marketing channels in Cianjur Regency, namely (1) farmers–collectors–wholesalers–consumers, (2) farmers– wholesalers–consumers, and (3) farmers–florists–consumers. The most efficient marketing channel is channel 2, with the lowest index, 1, and based on the Acharya & Aggarwal method, channel 2 has the highest efficiency value, 1.14. Therefore, it can be concluded that farmers' most preferred marketing channel is channel 1 (collectors), which is not the most efficient channel. Preferably, the farmers choose channel 2 (wholesalers) to sell the harvest of their chrysanthemum cut flowers so as not to rely on collectors. Keywords: farmer's Saham, marketing channel, marketing margin

Abstract

Indonesia, a country with high forest and land potential for economic growth, still relies on utilizing these two potentials. This study aims to create a conservation scenario in palm oil plantations that are expected to be able to mitigate surface runoff. The data collected include hydrology, land, area of oil palm plantations, and topography, which were analyzed based on threats and potential conservation that can be applied. Conservation scenarios that need to be carried out are: deadlock alley ditch (dad), mixed tree and palm oil plantations, planting oil palm without land cultivation, and immersing mulch. The simulation results of the dad design, if it rains heavily, all of the rainwater in the palm oil fields can be accommodated without a runoff. Mixed tree and oil palm plants are expected to maintain the availability of nutrients, increase the income of oil palm smallholders, and have a good impact on soil fertility. Planting oil palm without land cultivation is expected to reduce surface runoff, increase water infiltration into the soil, and expand water catchment areas. The immersion of palm mulch is expected to help retain soil moisture, add nutrients, enhance the soil's ability to absorb water, and prevent erosion. Conservation scenarios in the long term, such as dad, mixed tree and oil palm plantations, oil plantations without land cultivation, and mulch immersion, are expected to be able to mitigate flooding. Keywords: Arui watershed, conservation scenario, mitigation, oil palm, surface runoff

Abstract

This study aimed to estimate the level of efficiency and socio-economic factors that predispose the technical efficiency of shallot farming in Aceh Province based on differences in growing seasons. The data analysis method was estimated using the Stochastic Frontier Cobb-Douglas production function with the maximum likelihood estimation (MLE) approach. The 2014 Horticultural Crops Household survey data from the Central Statistics Agency (BPS). The number of samples was 143 shallot farming units. The results showed that seed production, fertilizer, labor, and the harvested area positively and significantly affected shallot output. Shallot farming in this province has been efficient at around 85,09%. Based on the growing season, the value of efficiency in the dry season is 90,08%, which is more efficient than farming in the rainy season, which is 70,03%. However, the technical efficiency value of shallots in the dry season and rainy season can still be improved. In addition to seasonal variables, significant factors affecting the efficiency of shallots are participation in farmer groups and land type, while education and seed sources have no considerable effect. The government's role is to provide quality seeds and conduct cultivation during the dry season to increase the technical efficiency of shallot farming. Keywords: farmer group, season, stochastic frontier, technical efficiency

Abstract

This study aims to calculate the amount of carbon lost and the amount of oxygen that can no longer be produced by the Cogreg Experimental Garden (KPC) due to the harvesting of Nusantara Unggul Teak wood (JUN). Carbon stock loss was measured using the allometric equation method based on the SNI 7724:2011. Calculating the loss of oxygen-producing potential used the comparison method of the atomic weights of carbon and oxygen. The results of this study indicate that the harvesting of JUN at KPC causes a loss of potential carbon storage reserves of 215.384 tons/year or equivalent to IDR7.2 bilions; the loss of oxygen-producing potential is 574,359 tons/year or equivalent to IDR2.66 billions. Meanwhile, the results of harvesting JUN wood can only produce a financial value of IDR1,36 billions. Therefore, the financial value of the KPC's environmental services in the form of carbon storage and oxygen production is much greater than the financial value of harvesting JUN's wood. Keywords: carbon loss, Cogreg Experimental Garden, Jati Unggul Nusantara, oxygen loss

Abstract

This study aims to determine the effect of various doses of rice husk biochar combined with organic amendments of cow manure and inorganic amendments of recommended fertilizer packages (urea, TSP, and KCl) on acid-sulfate soils. Over four months, the study was conducted in the Experimental Land of the Center for the Assessment of Agricultural Technology (BPTP) Pal IX, West Kalimantan Province. The study employed a randomized block design, with treatments including control soil, rice husk biochar 6 t ha-1, rice husk biochar 8 t ha-1, rice husk biochar 10 t ha-1, rice husk biochar 12 t ha-1, package of recommended inorganic fertilizer, package of recommended inorganic fertilizer + rice husk biochar 10 t ha-1, manure 10 t ha-1, and 10 t ha-1 + rice husk biochar 10 t ha-1. The findings revealed that single rice husk biochar amendments and their combination with inorganic and organic amendments had varying effects on the improvement of several physical properties of acid sulfate soils (density, total pore, moisture content, and penetration resistance). The amendment of a single biochar with a dose of 12 t ha-1 resulted in the lowest bulk density of acid sulfate soil, which decreased by 16% compared to the control soil. At a dose of 12 t ha-1, rice husk biochar produced the highest porosity and soil moisture content, 55% and 17%, respectively. The soil strength, as measured by the lowest penetration resistance, decreased by 30% in the treatment of manure 10 t ha-1 + biochar 10 t ha-1 (350 N cm-2) compared to the control soil. Keywords: biochar rice husk, soil amendment, soil properties of acid sulphate

Abstract

Purwakarta Regency is one of the regencies in West Java Province that plays an essential role in agricultural development. One of the efforts to encourage sustainable agricultural development is by developing potential commodities so that scenarios can be drawn up that are in accordance with the region's potential. Optimum land use scenarios with several constraint targets need to be prepared by considering food needs, ecological sustainability, and farm income. This study aims to identify land available for food commodities and simulate the land use allocation of food commodities in Purwakarta Regency to meet food needs, farm income, and tolerance for erosion. Location quotient index, shift-share analysis, land suitability & capability analysis, and Multiple Goals Programming were used to achieve research objectives. The identified leading commodities are peanuts, cassava, and sweet potato. We suggest 15 classes of land available for optimum land use allocation. Space optimization is organized into four scenarios considering erosion control targets, meeting farmers' minimum incomes, and rice production. The smallest erosion is 13,159 tons/ha/year, while the highest possible income is IDR300,500,000,000. The highest rice production is 202.070 tonsGKP, cassava production is 16,919 tons, sweet potato is 2.014 tons, and peanut production is 531 tons. Achieving production targets can support agricultural development and food security improvement programs through sustainable production improvement. Keywords: erosion, farming, income, land suitability, MGP

Abstract

The number of businesses like coffee shops (warkop) in Banda Aceh City makes every business actor required to implement the right strategy in capturing the hearts of consumers so that they can continue to visit that the company's income can increase. Therefore, this study aims to analyze consumer interest in choosing warkop in Banda Aceh City so that business actors can use the information obtained in making decisions to be applied to their business. The observation locations were carried out in five coffee shops. Based on the results of the study, several factors become a reference for consumers in choosing the warkop to visit, including location, place, price, internet, parking facilities, and mushalla. However, in some coffee shops, there are also problems in providing quality services, such as delays in the handling process, slight menu variations, the noise of places, parking lots, and less strategic locations. Thus, if the problem is not addressed properly, it is estimated that it can have an impact on the nature of the next consumer. With a soft systems methodology (SSM) approach, these problems can be overcome. SSM can build a conceptual model that can formulate a strategy for warkop business actors in Banda Aceh City. SSM method results in two suggested recommendation activities. First, technical recommendations, namely that business actors must make efforts in improving their companies, such as determining strategic locations, setting competitive prices, providing adequate parking space, and fixing various other factors. Second, policy recommendations include establishing special SOPs, developing human service resources, incorporating local wisdom, and innovating. So applying these two activity recommendations can provide answers to problems. Keywords: coffee shop, conceptual model, consumer interest, soft systems methodology

Abstract

Organic matter that is usually quite widely available around farmers' land can be one of the solutions in overcoming the problem of soil acidification and nutrient deficiencies in tropical highly weathered soils. However, one of the main problems in utilizing such organic matter on acidic soils is the diversity of its chemical composition, which affects the decomposition of the organic matter. In this study, a mixture of soil with five types of organic matter was incubated, namely cow manure, chicken manure, rice straw, legume plant residue, and their combination, with doses equivalent to 0, 7.5 and 15 tons/ha. Mixtures of soil with organic matter were incubated for 120 days under conditions of field capacity moisture. The aim was to evaluate the amelioration effect of the organic matter on soil acidification (exchangeable-Al and soil pH), available P, and phosphatase activity. The application of organic matter type and dose has a marked effect on decreasing the content of exchangeable Al and increasing soil pH, P-available, and phosphatase activity. Chicken manure application showed the best effect in lowering soil exchangeable-Al and increasing pH, available-P, and phosphatase activity. Keywords: amelioration, manure, phosphatase

Abstract

Oil palm plantation on peatlands is considered to contribute to increasing global warming by releasing CO2 as one of the greenhouse gases that cause global warming. The addition of ameliorants, such as biochar and zeolite, can absorb CO2 from soil respiration and store and filter it in their molecular pores. This research aimed to study the effect of ameliorant application on the CO2 flux, water content, microbial population, and enzyme activities. Ameliorant was applied to peat soil with two factors. The first factor was an ameliorant combination with 6 treatment levels: control (A0); zeolite (A1); biochar (A2); zeolite:biochar 75:25; zeolite:biochar 25:75; zeolite:biochar 50:50, and the second factor was 3 levels dose of treatment (% w/w): 1.5%, 3%, and 4.5%. Peat flux CO2 and water content were measured monthly for four months in the laboratory. Without mixing with biochar (A1), the results showed that zeolite suppressed CO2 flux and suppressed the decrease of water content better than other ameliorant combinations. However, different ameliorant dosage percentages did not show any significant results. Ameliorant application and incubation affected the microbial population and enzyme activities, and the results were varied. Chemical characteristics changed after 4 months of incubation. In conclusion, our results indicate that only zeolite amendment can suppress CO2 flux and decrease water content but did not affect microbial population dynamics and enzyme activities. Keywords: ameliorant, CO2 flux, enzyme activities, lignocellulolytic microbes, peat
