Abstract

Immersive Virtual Learning is learning that is considered meaningful for students to study climate change material which is considered complex because of the many interactions between the systems involved in it, and is considered to be material that is quite challenging for students. It is known that there are still many students who have limited knowledge about climate change so that learning methods are needed that can help them understand the climate change material well. This study aims to see how students' understanding after learning using the Immersive Virtual Learning (IVL) learning method, compared to the understanding of students using conventional learning methods. Using the Pre-Post Experiment Control Group Design design and involving 59 students who were divided into treatment and control classes, produced research data showing that students' understanding in the two classes experienced significant differences in improvement, but the increase in question was very small, even though the class treatment experienced a better increase than the control class. Based on this, it can be concluded that students' understanding has increased slightly after learning to use the Immersive Virtual Learning method. Further research is needed to develop the IVL method in order to provide better learning outcomes.

Abstract

The same rainfall can cause different degrees of water stress depending on soil type, so the production response shown by plants can be different. This study is essential for growers, especially in predicting oil palm production based on water deficit for each soil type. The study was conducted on oil palm plantations in Central Kalimantan, Indonesia, with four soil types in 1,446.15 ha (40 blocks). The source of data collected from oil palm plantations included bunch number, average bunch weight, rainfall, and soil physical and chemical properties for the last 15 years (2007 - 2021). This experimental study used a two-stage cluster sampling method. The results showed that the best productivity, bunch number, and average bunch weight were found on Ultisols. The four soil types tested showed the same annual production distribution dynamic, but the response rate from each soil type showed differences. Entisols and Spodosols were more prone to drought stress due to water deficit than Ultisols and Histosols because of the differences in soil texture. Water deficit causes a decrease in oil palm productivity by 5 - 22% in the first year (Ultisols 12 - 22%; Entisols 12 - 22%; Spodosols 7 - 19%;  Histosols 5 - 15%) and 1 - 8% in the second year (Ultisols 3 - 7%; Entisols 2 - 4%; Spodosols 5 - 8%; Histosols 1 - 5%) compared to previous years production. A decrease in oil palm productivity occurs at 3 - 5 months (bunch failure phase), 1 year (abortion sensitive phase), and 2 - 2.5 years (sex differentiation phase) after a water deficit appears.

Abstract

Climate change is a major threat to food security, especially for farmers in vulnerable areas facing the challenges of climate change. This study aimed to modify the plant genome to increase tolerance to extreme climatic conditions such as drought and high temperatures using genetic engineering methods based on CRISPR-Cas9 technology. Transgenic and control plants were grown in a laboratory experimental design with a quantitative approach. The results showed that the transgenic plants consistently outperformed the control plants under drought, high temperature, and low nutrient conditions. The transgenic plant showed a growth rate of 15.2 and average productivity of 25.7, higher than the control (12.3 and 19.1). Under high temperature conditions, the increase in productivity was even greater, reaching 33.2%, indicating that the inserted HSP gene successfully protects important proteins from heat stress damage. Genetic modification through the expression of genes such as DREB1A, HSP70, and PHR1 was shown to increase plant resistance to environmental stress. With these findings, biotechnology provides a real opportunity to build more adaptive and sustainable agricultural systems, supporting global food needs amid the intensifying challenges of global warming. This research is very relevant in answering the big challenge in the future, which is how to ensure biotechnology can be utilised sustainably to meet the world's growing food needs, without compromising ecosystems and biodiversity.

Abstract

Penelitian pengaruh pemberian campuran limbah solid kelapa sawit dan bokashi kirinyu terhadap pertumbuhan dan hasil mentimun bertujuan untuk menganalisis pengaruh serta takaran terbaik dari pemberian campuran pupuk organik limbah solid kelapa sawit dan bokashi kirinyu terhadap pertumbuhan dan hasil mentimun. Penelitian ini dilaksanakan di Desa Tajau Pecah, Kecamatan Batu Ampar, Kabupaten Tanah Laut, Kalimantan Selatan. Waktu pelaksanaan penelitian ini dimulai dari bulan Oktober 2020 sampai dengan Januari 2021. Penelitian ini menggunakan Rancangan Acak Lengkap (RAL) satu faktor yang terdiri dari 6 taraf perlakuan yaitu P0 (100% limbah solid), P1 (70% limbah solid + 30% bokashi), P2 (60% limbah solid + 40% bokashi), P3 (50% limbah solid + 50% bokashi), P4 (40% limbah solid + 60% bokashi), dan P5 (30% limbah solid + 70% bokashi). Setiap perlakuan diulang sebanyak 4 kali sehingga diperoleh 24 satuan percobaan. Hasil penelitian menunjukkan bahwa perlakuan pemberian campuran limbah solid kelapa sawit dan bokashi kirinyu tidak memberikan pengaruh yang nyata terhadap pertumbuhan dan hasil mentimun.

Abstract

Butterfly pea is increasingly valued as a functional flower crop because its petals are rich in flavonoids and anthocyanins, which are used as natural colorants and antioxidants. However, production on Ultisol is frequently constrained by poor soil fertility and limited nutrient availability. This study evaluated the effects of organic fertilizer source and application rate on vegetative growth, flowering, and phytochemical quality under greenhouse conditions. The study provides an integrated factorial assessment of these response domains across contrasting organic fertilizer sources and rates on Ultisol. A 3 × 4 completely randomized factorial design with three replications compared cattle manure, poultry manure, and water hyacinth bokashi at nominal as-received rates of 5, 10, 15, and 20 t ha⁻¹. Responses included vegetative traits, flowering time, flower number, total flavonoids, and anthocyanins. Fertilizer source, application rate, and their interaction significantly affected flower number, total flavonoid content, and anthocyanin content (all P < 0.001). Poultry manure at 15 t ha⁻¹ produced 48.11 flowers plant⁻¹, 27.00 mg mL⁻¹ QE total flavonoids, and 1.65 mg 100 g⁻¹ anthocyanins; flower number was 32.0% greater than with cattle manure at the same rate. Increasing poultry manure from 15 to 20 t ha⁻¹ reduced flower number, total flavonoids, and anthocyanins by 20.1%, 43.5%, and 43.0%, respectively. Rate responses were non-monotonic and fertilizer-source-dependent. Poultry manure at 15 t ha⁻¹ was the best-performing treatment among those evaluated for balancing flower production and phytochemical quality. These findings support source-specific organic nutrient management of butterfly pea on acidic Ultisols, although multi-location field trials and nutrient-equivalent comparisons are needed before broad recommendations can be made.
