Abstract

This study observed the spacing effect on arthropod diversity in soybean from November 2017 to January 2018. The treatments were arranged in a randomized block design, with five replications and five different spacings: A - 20x20 cm, B - 20x30 cm, C - 20x40 cm, D 20x50 cm, and E - 20x60 cm. The highest arthropods were found at the narrowest spacing (20x 20 cm) and the lowest at the broadest spacing (20x60 cm). Soybean plantations in the study area had a medium category for diversity index (H'), a fairly even category for evenness index (E), and a low category for dominance index (D). All types of relative index values did not differ between treatments.

Abstract

In recent years, the amount of coffee consumption by the Indonesian people has increased. As a result, there is an increase in coffee waste in the form of coffee grounds so it has the potential to have a negative impact on the environment. Proper management is needed so that coffee grounds are not wasted and pollute the environment. Composting is one way to convert coffee grounds into organic fertilizer. The provision of decomposers is useful for accelerating the composting process of coffee grounds so that it affects the quality of the compost produced. This study aims to determine the chemical quality of coffee grounds compost using different decomposers based on the Indonesian National Standard (SNI) 19-7030-2004. This research was carried out in the Compost House Department of Agroecotechnology and Soil Laboratory Department of Soil Faculty of Agriculture, Lambung Mangkurat University, Banjarbaru for three months, from June to August 2021. This research uses quantitative methods (laboratory analysis) to determine the chemical quality of coffee grounds compost. The treatments were decomposers, d1 = EM4, d2 = M21, d3 = Beka, and d4 = Petro Gladiator. The results showed that the use of EM4, M21, BeKa, and Petro Gladiator decomposers produced organic C, total N, P2O5, K2O, Ca, Mg, and C/N ratio of coffee grounds compost in accordance with SNI 19-7030-2004, but the pH value of coffee grounds compost treated with EM4, M21, BeKa, and Petro Gladiator decomposers did not meet SNI 19-7030-2004.

Abstract

The red traditional South Kalimantan cooking spice indicates that the seasoning has a deep red appearance. Although the habang cooking seasoning has a dark red appearance with the main ingredient red chili, this spice does not have a spicy taste but tends to taste sweet. This study aimed to determine the effect of different packaging and storage temperatures on the spice’s characteristics. This study used RBD method with 2 factors and 2 replications. Factor A is packaging variation and B is storage temperature. These observations included chemical tests, total microorganism tests, and sensory tests. Chemical tests and microorganisms were analyzed by the ANOVA and followed by the DMRT. Sensory test data were analyzed by the Kruskal Wallis and followed by the Post Hoc Test. Determination of the best results used the ranking method weighting. The results showed the characteristics were changed during storage. water content, peroxide number, and total microorganisms were increased in line with fat content and pH decreased. Sensitively, Habang cooking spices decreased in aroma, color, and viscosity during storage. The best Habang cooking seasoning was found in the use of cold temperature aluminum foil packaging on the 4th day of storage with a total parameter value of 8,224 and a total value of 30,195, chemical characteristics in the form of the water content of 31.46±0.02, a fat content of 69.67±0, 81, the pH value is 4.26±0.02, and the peroxide value is 3.15±0.06.

Abstract

Bacillus thuringiensis is a disease-causing bacterium in insects that is used to control insect pests that attack crops, both crops and horticultural crops. This bacterium can be isolated from plant residues that have become compost, infected insects, and soil. Isolation was carried out to take bacteria from their natural environment and grow them in artificial media. In swamps, there are important microorganisms involved in the decomposition of organic matter. The microbes that play a role consist of fungi and bacteria, for instance, those are found in rice plantations in Barito Kuala swamps, which include the Actinomycetes, Bacillus, Cromobacterium, and Pseudomonas bacteria groups. B. thuringiensis is widely distributed in nature but is rare due to the many different Bacillus isolates. Therefore, it was necessary to conducted research to determine the presence of B. thuringiensis in plant root areas in more specific soils to increase the possibility of finding B. thuringiensis. This study aims to determine the number of B. thuringiensis isolates obtained in type B tidal land ecosystems. This research was conduct from December 2021 to June 2022 at the Integrated Laboratory and Production Laboratory, Department of Agroecotechnology, Faculty of Agriculture, University of Lambung Mangkurat. This research used a descriptive method. Soil collection was carried out by purposive sampling (sampling technique with certain considerations) in the planting area in tidal land type B. Soil samples were taken from 3 places as a comparison, namely in the rice planting area, orange planting area, and banana planting area B. The parameters observed in this study were the number of colonies, the macroscopic and microscopic shape characteristics of the bacteria, the gram of bacteria, and the test of the killing power of bacteria against P. xylostella insects. Based on the parameters that have been observed, the highest number of colonies was found in citrus plantation samples, with 98 colonies.

Abstract

Meat is an important food commodity in meeting nutritional needs. Damage that leads to a decrease in the quality of fresh meat is mainly caused by microorganisms. One of the pathogenic bacteria that can contaminate broiler meat is Salmonella sp. This research aims to determine the food safety level of broiler meat sold in traditional markets in the city of Banjarbaru regarding contamination by Salmonella sp. bacteria and to prevent the circulation of poultry-origin products (broilers) that do not meet the required standards, which can threaten consumer health. The research method used in this study is a survey and laboratory analysis. This study utilized 56 chicken meat samples from 4 traditional markets using a random sampling method. The test results showed that 18 samples were contaminated with Salmonella sp. bacteria out of the 56 samples. This indicates that the quality of chicken meat sold in some traditional markets, 32.14%, does not meet the standards based on the Indonesian National Standard for chicken meat (SNI 7388:2009)

Abstract

Paddy plant chlorophyll is one of the determinants of plant growth and development, as photosynthesis plays a role in capturing light and transforming inorganic compounds into nutrients that plants need. The problem with the cultivation of paddy in the palm soil is the high saturation of the soil. There is a need for improvement in the ashes, ashes of palm powder, and empty palm cane ashes to lower the saturation. In addition, the application of jakaba LOF is necessary to boost the growth of milk dough crops, especially in the formation of chlorophyll. This research aims to determine the effect of jakaba LOF on the chlorophyll content of aromatic mentik susu rice in peat soil where ash ameliorant has been applied. This study used a nested factorial completely randomized design (CRD). The jakaba LOF application factor was nested in the type of ash ameliorant. The ameliorant type factor (s) consists of four treatments: s0 = no ameliorant, s1 = rice husk ash, s2 = sawdust wood ash, and s3 = empty oil palm bunch ash. The dose factor for LOF jakaba application (j) consists of two treatments: j0 = without application of LOF jakaba, j1 = application of LOF jakaba 15 mL-1. The results of the research showed that the application of LOF jakaba did not have a significant effect on the chlorophyll content of aromatic mentik susu rice in peat soil based on the type of ash ameliorant. Application of ash ameliorant to peat soil planted with milk aromatic rice can increase the chlorophyll b content and total chlorophyll of rice. Treatment without ash ameliorant (s0) can increase the chlorophyll b content and total chlorophyll content of rice by 16.45 mg mL-1 and 15.27 mg mL-1, respectively compared to the treatment of rice husk ash (s1), sawdust wood ash (s2), and empty palm fruit bunch ash (s3).

Abstract

Various agricultural wastes are used as ameliorants to improve degraded peat soils, with a focus on cases in Kalimantan. Peat soil is one of the potential land resources for agriculture in Indonesia, with an area ranging from 12.59 to 14.90 million ha, spread across Kalimantan, Sumatra, and Papua. However, the use of peat soil for agriculture faces many obstacles, such as low pH, low base saturation, organic acid toxicity, and macro- and micronutrient deficiencies. The use of agricultural waste as an ameliorant to improve degraded peat soil has prospects and opportunities. Agricultural waste is rich in nutrients and, if managed well, can contribute to sustainable agriculture. This review outlines the characteristics and potential of various agricultural wastes, such as animal waste, food processing waste, crop residues, and hazardous agricultural waste. These wastes are abundantly available and cost-effective, making them a valuable resource for increasing soil fertility and crop yields. This review provides insight into the application of agricultural waste as an ameliorant for degraded peat soils in Kalimantan and identifies challenges and opportunities in this context. This information is important in enriching future peatland management strategies in relation to increasing productivity and production of cultivated plants on peatlands.

Abstract

This research aimed to evaluate the interaction between chicken manure and tofu liquid waste-based liquid organic fertilizer (POC) on the growth and yield of pak choy, as well as to determine the individual and combined effects of chicken manure and tofu liquid waste POC on pak choy performance. The study employed a completely randomized design (CRD) with two factors. The first factor was chicken manure application: A0 (control), A1 (25 t ha⁻¹), and A2 (35 t ha⁻¹). The second factor was the concentration of tofu liquid waste POC: L0 (control), L1 (10%), L2 (15%), and L3 (20%). The experiment was conducted over three months, from February to May 2024, at the Sustainable Food Yard Demonstration Plot managed by the Palem Asri Komet Women Farmers Group. The results indicated a significant interaction between chicken manure and tofu liquid waste POC on plant height during the first and second weeks of growth. The combination of A1 (25 t ha⁻¹ chicken manure) and L1 (10% POC concentration) yielded the best results. Additionally, chicken manure alone significantly affected the number of pak choy leaves across all four weeks, with A1 again being the most effective treatment. In contrast, tofu liquid waste POC applied as a single factor did not significantly influence plant growth or yield.
