“…If the soil already has N 10 3 bacteria fixing bacteria per g of soil, then the number of bacteria inoculated must be more than 10 4 bacteria per g of soil [9]. Overcrowding of soybean plant populations reduces the root nodule' amount [12]. Phosphorus fertilisation and compost increased the number of nodules.…”

Plants have a vulnerability to climate change. Soybean plants must be able to adapt to climate change stresses so that physiological processes and plant development run well and produce optimal soybean seed production. Planting soybean cultivars that can withstand climate change is recommended to maintain soybean production. The effect of soybean cultivars and plant age on the nodules’ amount and leaf chlorophyll content planted during the wet-dry season needs to be studied. The study was designed with a factorial randomised block design and was repeated three times. The first factor is soybean cultivars, and the second factor is planting time. Parameters observed were weather data, chlorophyll content, nodules’ amount, and nodules’ mass. The results showed that the Gepak Hijau and Gepak Kuning cultivars planted at different times had significantly different root nodules’ amount and dry mass of root nodules, while there was no significant difference in chlorophyll content. The nodules’ amount positively correlated with the total chlorophyll. Relative humidity and rainfall reduce the nodules amount and the total chlorophyll. Solar radiation promotes growth in the nodules’ amount and the total chlorophyll.

“…Solar radiation is positively correlated with chlorophyll content (table 1). High light intensity without obstructions in the atmosphere increases the total chlorophyll of plant leaves [12]. The presence of obstruction of solar radiation in the form of rain and humidity can reduce the chlorophyll content.…”

“…The presence of barriers and diversity in habitat that divides the islands can cause genetic difference. According to Jannah et al (2022), isolated populations with distinct habitats or geographical conditions can stimulate the development of certain characteristics, resulting in different adaptation patterns and distinct genetic characteristics. Furthermore, Raji and Siril (2021) noted that geographical dispersion, isolation, and segregation within the species all influence genetic diversity at the species level.…”

Abstract. Yani A, Chasani AR, Daryono BS. 2022. Genetic diversity of eight maize Zea mays L. cultivars from East Nusa Tenggara based on inter simple sequence repeat markers. Biodiversitas 23: 4124-4130. East Nusa Tenggara (NTT) is one of Indonesia's island that has many local maize cultivars. However, the existence of this local corn is threatened by the presence of high-yielding maize seeds. Therefore, characterization of local maize cultivars using molecular marker is needed to conserve the germplasm. This study aims to determine the genetic diversity of local maize cultivars (Zea maysL.) from East Nusa Tenggara based on ISSR markers. This research used eight local maize cultivars (Watar Ohaq, Watar Puluq, Wata Bura, Wata Kuma, Wata Bunga, Pena Muti, Boti Pulut, and Latun Wara). Young leaves of maize were used for DNA isolation. Total genomic DNA was isolated using Genomic DNA Mini Kit for Plant (Geneaid). DNA was then amplified using 5 ISSR molecular markers (ISSR-807, ISSR-808, UBC-809, UBC-811, UBC-834). DNA band profiles were scored based on the presence or absence of bands. Genetic variability was analyzed based on the UPGMA method using the MVSP ver application. 3.1. Local maize from NTT has high genetic diversity (similarity index between 0.29-0.65). Local maize cultivars were separated into two main clusters at a similarity index of 0.43 and the grouping pattern was not influenced by the geographic location of local maize origin.

“…In response to this case, this research aims to provide modules that integrate Kupang localbased knowledge, namely Faloak plants, so that students in Kupang can respond to the current problem of students in scientific literacy and thinking skills in the respective regions. According to Jannah et al (2022), Faloak plants are medicine plants across East Nusa Tenggara, including in Timor Tengah Utara District, Kupang City, Indonesia. Faloak is traditionally boiled, brewed, and consumed to cure various diseases, as believed (Lalong et al, 2022).…”

“…3) The utilization of the Faloak plants as the learning material in the module is scarce. Based on the literature review conducted in several reputable journals, research regarding Faloak plants in Kupang is restricted to Faloak plants as the curing disease (Dean et al, 2019;Siswadi et al, 2021) and the anatomy and morphological aspects of the plants (Asmiati et al, 2019;Uslan et al, 2020;Jannah et al, 2022). Therefore, integrating the Faloak plant as the learning material is new and has become the originality of the current research.…”

Scientific literacy is an essential 21st-century skill that students must master. Scientific literacy is the proficiency to engage with scientific ideas and knowledge that shapes the student’s ability to interpret and evaluate data within scientific inquiry and make decisions regarding natural change, human activities, and technology. In addition to scientific literacy, thinking skills are crucial in the current era. Thinking skills help students solve social, scientific, and practical problems. Therefore, the current research objective is to test the effectiveness of the local-based knowledge module as a learning media to enhance student scientific literacy and thinking skills in Kupang Regency. 78 elementary school students in Kupang, Indonesia, were involved. They were selected based on the random sampling method and divided into experimental and control groups. The data were collected before using the module, during the use of the module, and after using the module. The instrument used to collect the data was tested for validity and reliability with expert validation. The collected data was then analyzed with SPSS 16 package software. Descriptive analysis and MANOVA were performed. The results indicate that the students’ average scores in scientific literacy and thinking skills are enhanced after they use the module. It is emphasized by the significance of the MANOVA analysis, which indicates the difference in score between the group of students who use the local-based knowledge module and those who do not. Based on the results, the module effectively enhances students’ scientific literacy and thinking skills. Therefore, this module can be used by teachers at the learning level to improve their scientific literacy and thinking skills.
