Abstract

This study aimed to determine the effect of dragon fruit peel extract on the motility and abnormalities of native chicken spermatozoa. The study was arranged experimentally using a completely randomized design consisting of 4 treatments and 3 replications. Before treatment, 12 native chicken were randomly divided into groups and adapted for 10 days with commercial feed and drinking water. The treatments were given orally for 8 weeks and consisted of P0 (control), P1 (1 ml dragon fruit peel extract), P2 (3 ml dragon fruit peel extract), and P3 (5 ml dragon fruit peel extract). Cement storage is carried out by the sequencing method. The quality of the collected sperm is tested in the laboratory. The parameters measured were microscopic sperm quality, namely sperm motility, and abnormalities. The results showed that dragon fruit peel extract had a significant effect on spermatozoa motility by increasing the percentage of motility but had no effect on spermatozoa abnormalities. Provision supplement of 5 ml dragon fruit peel extract gave the best results in increasing spermatozoa motility in native chickens.

Abstract

The purpose of this study was to determine the organoleptic value and pH of salted duck eggs with the addition of dragon fruit peel extract (Hylocereus polyrhizuz) at different levels. This study used a completely randomized design (CRD) with 4 levels of treatment and 3 replications, namely without the addition of dragon fruit peel extract, dragon fruit peel extract 5%, 10%, and 15%. The results showed that the addition of red dragon fruit peel extract as a ripening agent significantly affected the pH and organoleptic value of salted duck eggs. The average pH value ranges from 6.10-8.3. The average organoleptic value on a scale of 1-5 for color ranged from 2.38 to 4.39, aroma 2.87-3.78, taste 3.86-4.73. At the same time, the average hedonic organoleptic value (preference level) ranged from 2.85 to 4.71. Overall, the best concentration for all observation parameters was the addition of 10% red dragon fruit peel extract.

Abstract

Consumer demand for mustard needs in Indonesia is increasing. Efforts to produce mustard greens use an aeroponic system to utilize nutrients in dosage and type correctly. The study aimed to determine the proper type of nutrition for the growth and production of two mustard greens in an aeroponic system. This study used a completely randomized design with two factors. The first factor is the type of mustard which consists of two levels, namely pakcoy and pagoda. The second factor to consider is the nutrition applied at three different levels: AB mix, liquid organic fertilizer, and foliar fertilizer. Mustard greens grew and produced significantly differently when grown in an aeroponics system. Other nutrients greatly affected all observed variables, including plant height, leaf number, leaf color, root length, fresh plant weight, and dry plant weight. The use of pakcoy mustard provides the best growth and production of mustard greens compared to pagoda-type mustard. Giving AB mix nutrition to mustard greens can provide the best growth and production compared to nutrition from liquid organic fertilizers and foliar fertilizers. The AB mix nutritional treatment with pakcoy mustard produced the best results in plant height, leaf number, wet weight, dry weight, and root length. AB mix nutritional showing the best leaf color variable with pagoda mustard greens.

Abstract

Fish protein hydrolyzate (HPI) is a dry protein dosage form with more than 60% protein content. HPI is produced from breaking down fish protein into simple peptides and amino acids through the hydrolysis process by enzymes, acids, or bases. The HPI snakehead product is expected to increase the product's added value because it can be applied in the food and non-food fields. This study aims to obtain the papain enzyme concentration that produces the best HPI through the total residual solids (%) test and the degree of hydrolysis test. In addition, to get the proximate value of HPI flour with the best papain enzyme. Based on the total residual solids test (%) and the degree of hydrolysis (%), the best value was obtained in the treatment of adding 20% papain enzyme. This resulted in a value of 13.25% water content, 0.045% ash content, 20.81% protein content, and 0.28% fat content.

Abstract

Waste containing heavy metals is an environmental issue and is a concern of many parties. Heavy metal ions/compounds come from various activities such as the metal production industry, metal plating, mining operations, and leather tanning. Metal waste is one type of inorganic waste that we often encounter in Final Processing Sites due to the continuous accumulation of waste and produce pollutants in the form of leachate. Leachate has the potential to contaminate groundwater. This study aims to explore and identify morphologically bacteria obtained from soil contaminated with leachate and can degrade hazardous and toxic materials on waste containing heavy metals. Soil samples were taken from the landfill soil at TPA Tamangapa, Makassar, taken as a composite sample, while the bacterial isolation used the steak plate method. The research stages included bacterial cultivation, morphological tests, and calculating the number of colonies using the Total Plate Count (TPC) method. The results showed that 10 pure bacterial isolates could grow on NA media enriched with 5ppm lead metal.

Abstract

Sustainable cropping systems are part of a sustainable agricultural system in a broader sense. Some of the pillars of sustainable cropping systems commonly applied in Indonesia, such as vegetation succession, polyculture systems, cropping patterns, crop rotation, are discussed in this review. Furthermore, an analysis of the sustainable cropping system model was carried out: (1). Based on shade coffee plantations that are widely applied in Indonesian coffee plantations, (2). Based on the agricultural cultivation landscape in Bali Province known as the Subak system, which UNESCO has registered as a world heritage site, (3). Based on agroforest rubber plantations which are the local wisdom of Sumatra and Kalimantan.

Abstract

Sea grapes have high economic potential. The development of sea grape cultivation is inseparable from its cultivation techniques. The research objective was to determine the daily growth rate and chlorophyll content of sea grapes in different cultivation techniques. The research was conducted from September to November 2020 at the Polytechnic of Marine and Fisheries, Kupang, East Nusa Tenggara. The treatment in this study was a different cultivation technique with 3 treatments, namely by spreading it (scattering technique), using the substrate (substrate technique), and combining the spread and substrate (combined technique). The results showed no difference in daily growth rate and chlorophyll content even though using different cultivation techniques. The intensity of sunlight more influences the daily growth rate and chlorophyll content. Water quality parameters during the study supported the daily growth rate.

Abstract

Liquid waste is one of the negative impacts of the oil palm processing industry, which can disrupt aquatic ecosystems. This study aims to describe the morphometric conditions of the digestion system of tilapia (Oreochromis niloticus) exposed to palm oil wastewater. The study was conducted from April to July 2020. Tilapia measuring 4-7 cm in length with an average weight of 3-8 grams with 160 fish per treatment. The stages of the research included raising fish, giving oil palm liquid waste, and observing the morphometric digestion system. Fish were exposed to oil palm wastewater with concentrations of 0 mL.L-1, 47 mL.L-1, 70.4 mL.L-1, and 94 mL.L-1 for 64 days. The analysis was carried out on the Gastro Somatic Index (GaSI), Intestine Somatic Index (ISI), Relative Gut Lengths (RGL), Relative Intestine Lengths (RIL), and Hepato Somatic Index (HSI). The results showed that palm oil wastewater could affect the morphometric digestion of tilapia (Oreochromis niloticus). Palm oil wastewater with a concentration of 94 mL.L-1 also affected the GAS of 2.40%, the ISI of 5.49%, and RIL of 549.11%. In the treatment, the concentration of oil palm liquid waste was 70.4 mL. L-1 affected the HSI by 1.70%. However, exposure to palm oil wastewater does not affect RGL. The content of palm oil liquid waste can disrupt the metabolism of the stomach, intestinal, and liver cells. The high concentration of waste can damage the lining of the stomach and intestines, resulting in decreased appetite.
