Respon Bunga Pukul Empat (Mirabilis jalapa L.) terhadap Pencahayaan (Terik, Gelap, dan Ekstrem)
Full text linkThe four o'clock flower is one of many plants whose blooming time is influenced by photoperiodism. Long photoperiods can inhibit the initiation of flowering and slow down the development of flower primordia, leading to delayed blooming. This study aims to examine the photoperiodic response of four o'clock flowers (Mirabilis jalapa L.) to shorter durations of sunlight exposure. The research was conducted over one month (September–October 2024), with data collection carried out in Jalan Setia Budi, Tanjung Rejo District, Medan, from 5:00 AM to 10:00 PM.
The study involved observing plants growing in the same location to record the blooming times of the flowers. The data were analyzed descriptively and qualitatively, supported by literature reviews. The results indicated that Mirabilis jalapa L. plants under three different conditions—normal, complete darkness, and extreme conditions—showed slight variations in blooming times despite minor differences. On average, the flowers took 10 hours and 42 minutes to bloom. This suggests that minor environmental differences or specific plant factors may influence blooming times.
Further research is recommended to include flowers of various colors, such as white, red, and mixed hues, as well as to expand the study to villages with different altitudes to gain a deeper understanding of the effects of photoperiodism. As a member of the Nyctaginaceae family and Centrospermae order, the four o'clock flower (Mirabilis jalapa L.) is an adaptive plant that grows easily in home gardens with minimal care, making it an ideal subject for studies of this nature
Pengaruh Pemberian Pupuk Organik Cair (POC) Daun Papaya ( Carica papaya L. ) terhadap Pertumbuhan Tanaman Cabai Rawit ( Capsicum fritescens L.)
Full text linkCayenne pepper (Capsicum frutescens L.) is one of the horticultural crops that is widely cultivated by farmers because of its great demand by the community, not only in the household but also for industrial purposes and for export abroad. Cayenne pepper contains quite a lot of nutrients and quite a lot of benefits. The purpose of this study was to determine the effect of liquid organic fertilizer (POC) on papaya leaves (C. papaya) on the growth of cayenne pepper (C. frutescens). The study used a completely randomized design with three treatments namely liquid organic fertilizer (POC), positive control (K+) and negative control (K-). Each treatment was carried out in quadruples. The results of the ANOVA test with cayenne pepper showed: 1) the average value of plant height was 0.045; 2) the significance value of the number of leaves is 0.038; 3) The significance value is 0.273 for the number of branches. It can be concluded that the application of papaya leaves (POC) has a significant effect on cayenne pepper (C. frutescens) which has a very good value compared to the use of chemical fertilizers (NPK), so it is continued in the Duncan test experiment. The results of the Duncan test for cayenne pepper plant height showed that the POC treatment had a significant effect on plant height and number of leaves compared to the negative control (k-) and positive control (k+). This is due to the addition of organic matter from fermented cow urine and papaya leaves as well as nutrients in the soil, which can be beneficial both for the soil and for plants
Analisis Situasi Didaktis pada Modul Ajar Penjumlahan dan Pengurangan Bilangan Cacah Kelas 2 Sekolah Dasar
Full text linkThis research aims to describe how students’ understanding of adding and subtracting whole numbers is formed. This research is a qualitative descriptive study with teaching modules as the main data source. After surveying didactic situation theory in mathematics through various sources, the paradigm in this theory is then used as a basis for describing learning activities contained in the teaching module. Learning activities in the teaching module are classified based on the theory of mathematical didactic situations. The result shows that in these learning activities, the didactical situation was not developed sequentially. Apart from that, the action situation that is constructed does not show the existence of a dialectical situation between individual students and the milieu. Knowledge construction tends to come from teacher explanations, not from the process of solving problems that involve students' mental activity. This condition can potentially cause knowledge not to be constructed properly, making it possible for students not to be able to use it when facing new mathematical problems and allowing learning obstacles to occur.
