Abstract

This research aimed to provide an overview of the practicum design regarding the differences between animal cell and plant cell used in Student Worksheet in Banyuwangi Regency. The samples used were 6 Student Worksheets of practicum work on animal and plant cells consisting of 3 Student Worksheets from the education unit level curriculum (hereafter, KTSP) and 3 Student Worksheets from the curriculum 2013. The sampling technique used in this research was purposive sampling. The instruments used were obtained from the Biology Education Lecturers Team of Indonesia University of Education which consisted of relevance aspect, Competency Aspect, practical aspect and knowledge construction analysis of Vee Diagram adapted from Novak & Gowin (1984). The results of the analysis showed the following: 1.) relevance aspect, not in accordance with the demands of Basic Competence, 2.) Competency Aspect, there were no objects or phenomena that could be observed and the ability to think was only limited to C1, 3.) practical aspect, showing that the suitability of the tools , materials and practicum steps still did not meet the practicum standards, and 4.) the knowledge construction of title/objective had not been focused, the object of the phenomenon could not be observed and only a few theories, principles, and concepts could be identified. This shows that the role of Student Worksheet in practicum activities has not been optimal and practicum reconstruction is needed so that practicum activities can run optimally.

Abstract

Liquid coffee waste has the main component in the form of organic matter which is very resistant to increasing pollutant loads. Preliminary research results show that the level of pollution exceeds the quality standard with the test results of 23 ppm BOD and 72 ppm COD, so we need a way to prevent pollution. One way that can be used is the phytoremediation method by utilizing plants as pollutant degrading agents. The purpose of this research was to determine the effectiveness of lotus in degradation of BOD and COD of liquid coffee waste. The research method used an experimental method with a Completely Randomized Design consisting of four variations of lotus biomass 0 g, 25 g, 50 g, and 75 g with three replications within 6 days. The results showed a degradation of BOD and COD levels varied. The most effective treatment for lotus phytoremediation on day 3 was P3 with a biomass of 75 g resulting in a degradation of BOD and COD reaching 72% and 71% which met the PP RI No. 82/2001 with a maximum limit of 3 ppm BOD and 25 ppm COD. The results of the homogeneity of variance test showed that the four treatments had homogeneous variance and analysis of variance showed that F count > F table 5% (4.07) and > F table 1% (7.59). These results indicate that lotus is effectively used as phytoremediation of liquid coffee waste. The conclusion of this research is that lotus is effective in BOD and COD degradation of liquid coffee waste.

Abstract

Malaria is a vector-transmitted disease with a high number of cases. Plasmodium parasites are transmitted from the body of the Anopheles mosquito to the host through several mosquito organs, including the salivary glands and the midgut. The salivary glands and the midgut, apart from being a breeding ground for parasites, are known from several studies that various types of microbiota inhabit these two organs. The group of bacteria is the most widely known to be associated with Anopheles mosquitoes. The bacteria found were dominated by Gram-negative bacteria, with Pseudomonas being the most common, followed by Aeromonas, Asaia, Comamonas, Elizabethkingia, Enterobacter, Klebsiella, Pantoea, and Serratia. The group of Gram-positive bacteria was represented by the genera Bacillus, Streptococcus, Lactobacillus, and Staphylococcus. Each species of Anopheles has a different composition of associated bacteria. Anopheles-associated bacteria currently receive much attention because of their role in fighting Plasmodium infection. The ability of malaria vector-associated bacteria to inhibit and fight Plasmodium infection is divided into three mechanisms. Bacteria can triger an immune response through the Immune-deficiency (IMD) pathway, which causes active anti-Plasmodium and the production of antimicrobial peptides, increasing ROS synthesis and microbiota, which trigger hemocyte differentiation to protect against Plasmodium. This function related to inhibiting Plasmodium development needs further research so that later it can become an option for vector-based malaria control without damaging the sustainability of the environment.

Abstract

In Indonesia, the agribusiness sector has begun to expand due to the increase in entrepreneurship of orchid plants. Several genera and species of orchid plants are promising to be traded as ornamental plants, one of which is the moon orchid (Phalaenopsis amabilis). However, the limited number of seeds or plants produced by conventional propagation methods takes a long time to get new tillers. Therefore, tissue culture techniques can be used to grow and reproduce moon orchid plants. In the success of in vitro culture, the balance of growth regulators is an essential factor. On the other hand, synthetic hormones such as 1-naphthalenaecetic acid (NAA) and 6-benzylaminopurine (BAP) are relatively expensive. The study in this research is to substitute the synthetic hormones NAA and BAP with organic ingredients that are cheap and easy to find. Such as Purple Sweet Potatoes and Beans and find out the right concentration of organic matter. This study used a completely randomized design with two factorials (concentration of purple sweet potato and green beans) with three repetitions. PLB (Protocorm Like Bodies) moon orchid (Phalaenopsis amabilis) was treated with: positive control (2 ppm), negative control (without the addition of organic or synthetic hormones), and variations in the concentration of purple sweet potato and green beans organic matter. The result was that C4D0 (500g/L purple sweet potato extract and 0 g/L green bean extract) was an excellent formulation, although there was no significant interaction between purple sweet potato and green bean extracts against moon orchid.

Abstract

Salak seed are used as natural diuretics, it's contain secondary metabolites i.e alkaloids, flavonoids and tannins. Diuretics are compounds that can increase the rate of excretion of urine volume and increase the excretion of mineral salts in the urine. The study was to determine the diuretic effect of salak seed extract on the histopathological structure of the kidney. Salak seed extract was made by maceration method using 70% ethanol and then evaporated. Rats were divided into 4 treatment groups, negative control and 3 treatment groups with the administration of salak seed extract for 7 days orally at a dose of 0.28g/kg body weight, 0.56g/kg body weight and 1.12g/kg body weight. The results showed that the treatment of salak seed extract orally for 7 days could increase urine volume. The treatment of dose 1.12g/kg body weight had highest diuretic effect as indicated by the volume of urine produced 5.00 ml. The treatment salak seed extract had no effect on creatinine and urea levels. The all treatment doses of salak seed extract had no effect on the kidney histopathological structure, i.e it was not effect on glomerular diameter or did not cause atrophy of kidney glomerular.
