Abstract

Peningkatan polutan logam berat kadmium (Cd) di persawahan menjadi masalah lingkungan yang serius karena dapat menimbulkan toksisitas dan berakibat pada penurunan pertumbuhan tanaman pangan yang tidak toleran. Gejala toksisitas Cd pada tanaman dapat dikurangi dengan memanfaatkan unsur benefisial seperti silikon (Si). Namun, peran Si dalam mengurangi gejala toksisitas Cd pada padi ‘Cempo Merah’ belum banyak diteliti. Tujuan penelitian ini yaitu mengkaji peran Si dalam meningkatkan pertumbuhan dan kadar klorofil padi ‘Cempo Merah’ yang tercekam logam berat Cd.Penelitian ini menggunakan desain Rancangan Acak Lengkap 2 Faktorial, yakni perlakuan 3CdSO4.H2O­ dan CaSiO3 (masing-masing dengan konsentrasi 0, 50, dan 100 mg.kg-1 tanah), dengan 3 kali ulangan. Data penelitian dianalisis menggunakan ANOVA (analisis sidik ragam) dan uji DMRT (Duncan Multiple Range Test) pada p 0,05. Hasil penelitian menunjukkan bahwa perlakuan Si (100 mg.kg-1 tanah) efektif meningkatkan pertumbuhan dan kadar klorofil padi ‘Cempo Merah’ baik dalam kondisi tidak tercekam maupun tercekam logam berat Cd. AbstractIncreasing cadmium (Cd) in rice fields become a serious environmental problem because it can cause toxicity and decrease the growth of intolerant food crops. These toxicity symptoms can be reduced by utilizing beneficial elements such as silicon (Si). However, its role in rice 'Cempo Merah' has not been much studied. This study aimed to examine the role of Si in increasing the growth and chlorophyll content in the rice ‘Cempo Merah’ under Cd stress. This study used a Complete Randomized Design, two factorials, namely 3CdSO4.H2O and CaSiO3 (each with 0, 50, and 100 mg.kg-1 of soil concentrations), with 3 replications. The research data were analyzed using ANOVA and Duncan’s test at p 0.05. The results showed that Si (100 mg.kg-1) effectively increased the growth and chlorophyll content in rice both under Cd stress and normal conditions.  Keywords: silicon, cadmium, growth, chlorophyll, rice AbstrakPeningkatan polutan logam berat kadmium (Cd) di persawahan menjadi masalah lingkungan yang serius karena dapat menimbulkan toksisitas dan berakibat pada penurunan pertumbuhan tanaman pangan yang tidak toleran.

Abstract

Nitrogen does not directly have advantages in human physiology system, but it holds one of the most critical roles in plants’ life cycle and productivity. Even though Nitrogen is the most abundant elements in the atmosphere, it is also the most deficient essential nutrients in plants. The proposed idea of the nitrogen-fixing GM crops, particularly wheat, is aimed to overcome those stated cons of the traditional diculture and nitrogen fertilizer. This analysis focus on the overview as well as the pro and cons of the genetically modified nitrogen-fixing plants in providing a better agricultural method. The genetically modifying method to generate a nitrogen-fixing non-legumes carries a significant chance of failure results and hindrance. The multilevel implication occurs when we need to modify the plants that not normally produce nodules in their roots to form the nodules and to modify the Nitrogen-fixing microbes to live in the nodules of non-legumes, which are not their natural dwelling places.In conclusion, the genetically modified crops project to fix their Nitrogen is feasible, but the difficulties and the funds needed still outweigh the benefits obtained in the future. With all of those limitations, the target goal to erase famine in 2050 just by funding the nitrogen-fixing wheat alone seems to be too high to be reached. The funds and efforts should be better spent on other factors and farming methods.

Abstract

Study of the genetic relationship between bananas carried out in Kabawetan Subdistrict, Kepahiang District, Bengkulu Province, from April to October 2019. Data collection on banana exploration studies is carried out in several locations of houses and community gardens in the form of wild plants and cultivation. Morphological data were compiled based on observations of morphological characters of specimens in the field, the character status was adapted from banana descriptors (IPGRI 1996). Morphological characterization results were observed and continued with character selection based on kinship in the form of a tree phenogram. Data were analyzed using the Numerical Taxonomy System (NTsys-pc) 2.02 program with the Unweight Pair Group Arithmetic Mean Method (UPGMA). The results found 6 types of banana diversity collection from 32 pseudo stands (individuals). The collection results obtained in the field are 1 collection of wild bananas and 5 cultivation collections. There are 6 banana distribution locations, namely Mekasari Village, Sumbersari Village, Babakan Village Bogor, Sumbersari Village, Tugu Rejo Village, Sido Rejo Village. Kinship of 6 types was found to have a similarity coefficient between 0.27 - 0.63. Phenograms divide into 2 large groups of 6 types of bananas, namely group A and group B, these two groups are separated by a similarity coefficient value of 0.27. Group A has a total of 5 types of bananas namely kapal, kapok , gembor, and jantan bananas.

Abstract

The increasing length of toll roads on the island of Java also increases the number of green lane that can be used for greening. One of the functions of the green road is for planting carbon-absorbing plants. Tamarind (Tamarindus indica) trees are a type of productive plants that have a carbon sink function. The purpose of this study is to estimate the carbon stock of a model of planting on the green lane of the Semarang-Solo toll road. This research was conducted in September 2019. The method used in this study is simulation calculation and allometric models. Calculation simulation method is used to determine the potential availability of land along the green lane of the Semarang-Solo toll road. Carbon reserve calculation method is done by nondestructive sampling by using an allometric model for the tamarind tree species. The application of this model can produce estimates of stored carbon stock approximately 197.165 ton. Green lane has a very large utilization potential for carbon sequestration and should be used optimally.

Abstract

The Springs of Tiga Rasa Rejenu is one of the springs located at one of the peaks of the seven peaks in the Muria mountains. The Tiga Rasa Springs are located at the peak of Argo Wiloso Rejenu, Kudus Regency. The diversity of vegetation around the Tiga Rasa Springs has an important role in the sustainability of springs source and discharge. This study aims to determine the composition of plants, vegetation forms, the index of importance value of vegetation components, and the abiotic environment impact around the springs. The method used is explorative descriptive analysis by dividing the area into four research stations based on the direction of the eye. At each research station there are three sample plots. Each station is divided into three sampling points with a size of 20m x 20m for trees, 10m x 10m for poles, and 5m x 5m for saplings and 2m x 2m for seedlings. Abiotic environmental parameters measured are air temperature and humidity, light intensity, soil temperature, soil pH, total dissolved solids, and water salinity. The research results around the Tiga Rasa Rejenu spring are that the H' values at the highest level of see dlings is fern Diplazium esculentum, the H' values at the highest level of saplings is the royal palm tree Roystonea regia, and the H' values at the highest level of poles and trees is Pterocarpus indicus. At all stations obtained average H’ value is 1.96 then the vegetation around the Tiga Rasa spring classified to medium plant diversity and medium community stability. Abiotic factors effect on the environmental conditions around the Tiga Rasa Rejenu springs.

Abstract

The lack of participation of men in family planning programs is due to the limited choice of male contraceptive. Traditional medicinal plants are one of ideal alternative types of male contraception. This study aimed to study the effect of Cyperus rotundus L. rhizome on the quality and quantity of spermatozoa in male mice (Mus musculus L.). Twenty male mice were divided into four treatment groups, namely control group (C0), the dose of teki grass rhizome extract 4.5 mg/40 g BW (C1), the dose of teki grass rhizome extract 45 mg/40 g BW (C2), and the dose of teki grass rhizome extract 135 mg/40 g BW (C3) for 35 days. Parameters measured were the motility, viability, morphology, and concentration of spermatozoa. The data were analyzed for diversity and then further tested using the LSD test with a 5% significance level. The results of the analysis showed that giving teki grass rhizome extract had a significant effect on the motility, viability, morphology, and concentration of spermatozoa. It can be concluded that teki grass rhizome can be used as an alternative male contraception because it can reduce motility, viability, morphology, and spermatozoa concentration.

Abstract

This needs analysis aims to determine the problems that occur in Biology learning activities at SMAN1 Anggana. Application of learning models that suit students' needs. The research sample in this analysis is a class X student at SMAN 1 Anggana. The results of the observations showed that as many as 50.00% of the students' daily daily test results used the lecture method. This is because several things include students not paying attention to the teacher during the learning process, students playing with their peers, and monotonous learning. The teacher states that students tend not to ask questions in learning. In addition, the problem that is also faced is that there are still many teachers who apparently have not implemented learning models that can make students more active so students tend to be saturated. The way that can be taken to overcome this problem is by applying the team games tournament (TGT) learning model and the student teams achievement division (STAD). From the observations in the form of analysis of the problems of Biology teachers and students of SMAN 1 Anggana, it can be concluded that the ability of teachers to overcome problems in learning needs to be improved so that students are more active and happy to learn biology.
