Sorghum is a multifunctional crop as a source of food, feed, and alternative energy. Plant breeding using the radiation mutation technique was applied to improve the characteristics of sorghum according to its purpose. This study evaluated the agronomic and fiber characteristics of selected sorghum mutant lines. Eight sorghum mutant lines were observed in this study (GHP-2, GHP-3, GHP-4, GHP-5, GHP-7, G-5, P-341, and P36.M10). Pahat and Bioguma sorghum varieties were used as control. Compared to eight selected mutant lines, Bioguma variety was the tallest plant. Except for P-341, all selected mutant sorghum lines produced lower plant biomass than Bioguma. The highest sugar content was produced by G-5 and P-36.M10. There are no significant differences in seed production per panicle. The lowest fiber fractions in the leaf and stem were produced by GHP-3 and G-5 mutant lines, respectively. Based on our findings, the P-341 sorghum mutant line can be used as forage sorghum because it produces high biomass and relatively low fiber content. The G-5 mutant line can be projected as an alternative energy source due to its high stem sugar content. Keywords: agronomy, fiber, mutant, sorghum

Bogor is one of the cities with a very rapid development rate, so the need for sand for construction is very high. There are plenty of sand sources in Bogor, feeding by 2 major rivers and 7 tributaries, including the Ciapus River. This river is a job opportunity for sand miners. Based on the study results, the traditional sand mining model is applied. The income from the sand miners is IDR100,000/m3, while the income from the collectors who also distribute the sand to the users is IDR150,000/delivery. The positive impact of this activity is that it can reduce sedimentation in the Ciapus River, while the negative impact is that it caused a change in the shape and function of the river and the road damage around the mining due to the sand transportation, but not on the road within the housing area. In the long term, this activity needs more attention because until now, the Bogor Kota Government still needs to have a regulation regarding type C mining.

The difference in seasonality in the red chili farming business affects the allocation of the use of production factors and the availability of its supply in the market, which is suspected to affect the cost structure and revenue of the farming business. This study aims to calculate the cost structure, revenue, and earnings of red chili farming businesses in the dry and wet seasons in Central Java Province. Data was collected from the 2013 Agricultural Census: 2014 Horticultural Crop Business Household Survey and a 2535 red chili farmers sample. The methods used include the analysis on income, cost and revenue structure, revenue, R/C ratio, and Mann-Whitney differential test. The results showed that the cash and overall costs of farming red chili in the dry season were higher than in the wet season. So are the total and cash revenues. Farming in the dry season is more profitable in terms of cash income, net farm income, R/C ratio, return to total capital, and return to land, which is higher than in the wet season. The results of the Mann-Whitney difference test showed a significant difference in the income factors and R/C ratio of the red chili farm business in the two seasons.

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.

Nitrogen (N) fertilizer of the urea type is very commonly used in Indonesia. The demand for this fertilizer is expected to increase, so an alternative is needed as a complement. Ammonium chloride (NH4Cl) is a by-product produced in the soda ash industry. This compound contains 26% N, which can be an alternative source of N nutrients for plants. The level of the following element, namely chlorine (Cl), is relatively high, so it is a concern that might affect the plant growth. This field experiment aimed to evaluate the effect of the application of ammonium chloride combined with potash fertilizers on the growth, production, and uptake of N and Cl nutrients in sweet corn plants. The trial was designed in a randomized group with nine treatments of 0%, 100%, 150%, and 200% N, combined with potassium sources from KCl and K2SO4. As a comparison, the source of N is urea at a dose of 100% N is referred to as the standard N treatment. Parameters observed included plant height, the weight of corn cobs and corn stover, N and Cl nutrient uptakes in seeds, leaves, and stems. The results showed that the application of ammonium chloride combined with different K sources markedly affected plant height, cob and plant stover weight, and N and Cl uptakes of sweet corn compared to controls. Applying N-ammonium chloride with KCl and K2SO4 showed no significant effect in growth and yield compared to standard N. The N dose showed no significant effect on plant growth and yield compared to the standard N dose. Keywords: by-product, nitrogen fertilizer, soda ash

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.

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

Sorghum is a potential crop as feed forage. The objective of the research was to obtain optimum dose of liming to improve the growth and productivity of sorghum (Sorghum bicolor (L.) Moench) biomass as feed forage. A completely randomized design with 4 treatments and 4 replications were applied for the research. The treatments were doses of dolomite lime addition i.e., 1) SD0 (dolomite lime addition at a dose of 0 ton/ha) as a control, 2) SD1 (dolomite lime addition at a dose of 1 ton/ha), 3) SD2 (dolomite lime addition at a dose of 2 ton/ha), and 4) SD3 (dolomite lime addition at a dose of 3 ton/ha). The result shows that supplementation of dolomite lime at doses of 2‒3 tons ha-1 can increase soil pH after a week of incubation. The dolomite lime addition at a dose of 3 tons ha-1 significantly increases (P<0.05) the plant height (2 weeks after planting) and the number of leaves from a week after planting until the end of the research (10 weeks after planting). In addition, this dose of dolomite addition (3 tons/ha) can increase fresh biomass productivity as well as dry biomass compared to control (SD0). In conclusion, supplementation of dolomite lime at a dose of 3 tons ha-1 was effective to increase the pH value of soil, plant height, leaves number, as well as fresh and dry biomass of sorghum plant. In addition, this dose of dolomite lime produces better green color of sorghum plant leaf compared to without liming. Keywords: biomass production, dolomite lime, feed forage, Sorghum bicolor (L.)

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.

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. \u0000 \u0000Keywords: aloe vera powder, coat spraying, Cosmos sulphureus, edible flower, kenikir flower","PeriodicalId":31211,"journal":{"name":"Jurnal Ilmu Pertanian Indonesia","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49504591","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
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.
