Abstract

Oyster mushroom (Pleurotus ostreatus) can grow well on materials that contain carbohydrates. One of the fungal growth ingredients that contain carbohydrates is corn flour. In addition to corn flour, molasses can also be used to stimulate the growth of white oyster mushrooms. The purpose of this study was to see the effect of variations in the concentration of molasses and corn flour on the growing media on the productivity of white oyster mushroom (Pleurotus ostreatus). The research was conducted in May-July 2022 at the Center for Breeding and Development of Oyster and Ear Mushroom Cultivation on Sunggal District, Deli Serdang Regency. The research method used was a factorial completely randomized design (CRD) with 2 factors, 16 treatment combinations and 2 replications so that there were 32 baglogs. The first factor contained 4 levels of treatment, namely M0: 0 ml/baglog, M1: 7.5 ml/baglog, M2: 15 ml/baglog and M3: 22.5 ml/baglog. The second factor has 4 levels of treatment, namely J0: 0 gr/baglog, J1: 10 gr/baglog, J2: 20 gr/baglog and J3: 30 gr/baglog. Parameters observed were mycelium growth rate (cm), stalk height (cm), hood diameter (cm), hood thickness (mm), number of branches/clumps, wet weight (g). The results of the highest data mycelium growth rate in treatment J0 of 20.75 cm. The result of the highest data stalk height in the M1 treatment was 6.19 cm. The results of the highest data hood diameter in treatment J0 of 10.18 cm. The result of the highest data hood thickness in treatment J2 was 5.09 mm. The result of the highest number of branches/data clusters in the M3 treatment was 9.13 branches. The result of the highest wet weight (g) data in the M3 treatment was 140.75 gr.

Abstract

The community carries out bathing and washing activities directly in the retention basin which can cause polluted water. Water quality checks need to be carried out before treatment. The purpose of this study was to determine the quality of water in the retention basin. Determination of the sampling location by purposive sampling. Sampling was carried out once in August 2021. Parameter measurements were carried out in the field and in the laboratory. The measurement results are compared with the quality standards listed in the Regulation of the Minister of Health of the Republic of Indonesia Number 32 of 2017 concerning Environmental Health Quality standards and Water Health Requirements for Sanitary Hygiene, Swimming Pools, Solus Per Aqua and Public Baths. A parameter that passed the quality standard was E-Coli while pH, hardness, nitrate, temperature, and TDS still met the quality standards. Retention basin water in Tubuhue Village seen from the parameters of temperature, pH, TDS, hardness, and nitrate can be used for sanitation hygiene purposes, but judging from the parameter E-Coli cannot be used for sanitary hygiene purposes.

Abstract

Misconception is a problem where an individual experiences a misinterpretation related to an understanding that has been agreed upon and is considered correct by experts. The circulation system is one of the biology learning materials with complex concepts and has the potential to create gaps for misconceptions. This study aims to identify misconceptions about the circulation system material in class XI MA PPKP Darul Ma'La Winong Pati students. This type of research is quantitative and uses descriptive and non-experimental methods. The subjects of this study were 30 students from class XI MIA 1 and 2 for the academic year 2021/2022 who were selected by random sampling technique. The instrument in this research is a student's ability test using a three-tier diagnostic test. Based on the results of the study, it was found that misconceptions exist in all concepts of the circulation system material with an average percentage of misconceptions reaching 73.2% (high category). The concept with the highest level of misconception is the blood clotting mechanism by 80% and the lowest is the concept of circulatory function by 53.4%. The cause of this misconception is due to internal factors such as student understanding, as well as external factors, namely the way teachers teach and the use of the internet as a source of information

Abstract

Shrimp waste is a perishable material. The degradation process is carried out by decaying microbes by producing degrading enzymes. The presence of chitin content in shrimp waste causes the emergence of chitinase enzyme-producing bacteria. Chitin is a linear homopolymer composed of N-acetyl-D-glucosamine monomers with -(1,4) glycosidic bonds. Chitin has unique properties, namely; biodegradable, biocompatible and non-toxic. This causes chitin and its derivatives to be widely used in various industrial and biomedical applications so that chitin and its derivatives have great economic value. There were 10 isolates of chitinolytic bacteria from shrimp waste with varying morphological characteristics. The ten bacterial isolates were NR02, NR03, NR04, NR05, NR06, NR07, NR08, NR09, NR10, NR11 and PU01. Chitinolytic index CI value > 2 was produced by 4 bacterial isolates, namely; NR02, NR07, NR09 and PU01. The lowest IK value was generated by NR08 with a value of 0.01. The chitinolytic bacteria obtained have different characters and it is very likely that they come from different types

Abstract

One of the commodities of freshwater fish species that live in swamps and rivers that have high economic value is snakehead fish. In addition to having economic value, it also has a high albumin content and has various functions for health so it is very useful in the medical and industrial world. Snakehead fish is very rich in albumin, which is an important type of protein. There is 60% protein in plasma found in albumin, albumin in the blood functions to increase endurance, and is able to regulate the water balance in cells, waste products can also be removed, in the formation of new cells nutrients can be given so as to accelerate the recovery of body tissue that is split. post operation. The thing that must be considered at the time of feeding is the right amount, time and use. Therefore, the types of natural food that can be used as snakehead fish feed are silk worms (Tubifex sp), water fleas (Daphnia), small freshwater fish (gobies/tilapia). In this study, the design used was a non-factorial completely randomized design (CRD) with three treatments and three replications. From the results of the study, the highest growth of snakehead fish (Channa striata) was found in treatment A, namely absolute weight 6.61 grams, and average The average absolute length growth is 3.13 cm. The highest survival rate was in treatment A, which was 100% and the lowest was in treatment C, which was 76.6667%
