Abstract

Spodosols have been widely used for oil palm plantations, specifically in Kalimantan, Indonesia. However, they are sub-optimal for agriculture due to a lack of water and nutrient-holding capacity and a spodic layer that limits plant root development. Therefore, proper agriculture practices are needed for oil palm to enhance its potential yield. This study aims to determine the effect of the mounding technique on the physiological performance and yield of oil palms in spodosol. The study location was well-managed, with eight blocks of oil palm plantations planted in 2008 on spodosols (Typic Haplohumod) in Central Kalimantan. The mounding technique was applied to four blocks of oil palm planted in 2015, while the remaining four were left without mounding. The parameters observed were soil moisture, transpiration, number of bunches, bunch weight, and yield. The results showed that the average moisture in the mounded soil was 4% greater than the control.  Additionally, the average daily transpiration of oil palm with the mounding was up to 2.30 mm day-1 or three times higher than the control.  The implication was that the average yield of oil palm increased from approximately 1.84 to 3.71 tons ha-1 year-1 compared to no-mounding treatments. Furthermore, the average yield was 19-66% higher than the block without the mounding application.

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

X-ray diffraction (XRD) data and the Scherrer equation were utilized to analyze the crystallite Size of titanium dioxide (TiO2) in a solution of ethylene glycol (EG) and distilled water. The XRD analysis was conducted using a Rigaku Miniflex 600 instrument with an X-ray wavelength of approximately 0.15046 nm. The examination yielded the full-width half maximum (FWHM), which was subsequently examined using the Scherrer equation. This experiment employed TiO2 with a purity level of 99.8% and a crystal Size of 30 nm. The analysis revealed that the average crystallite Size of TiO2 in the sample is 19.45 nm, with the highest measurement at about 30.38 nm. The Spearman correlation equation was employed to validate the outcomes. The Spearman's correlation coefficient between the FWHM variable and the crystallite Size of TiO2 nanoparticles is -0.958. These findings shed light on the crystal structure of TiO2 under these conditions. These findings lend support to the use of TiO2 in a variety of nanotechnology applications. However, more research is needed to understand fully how crystallite-Size TiO2 nanoparticles work in different settings and to find the best ways to prepare samples, including understanding the specific phase and how it affects the stability of fluids. This research contributes significantly to the understanding of the properties of TiO2 in a solution of distilled water and EG, as well as to the characterization of nanomaterials, with particular emphasis on issue 9 of the SDGS Goal concerning industry, innovation, and infrastructure.

Abstract

Pembelajaran sains bukan hanya menekankan kepada penguasaan produk saja, tetapi juga pada penguasaan keterampilan proses serta sikap ilmiah, maka dari itu setiap sekolah hendaknya menekankan keterampilan proses sains diantaranya observasi, inferensi, pengukuran, mengkomunikasikan, mengklasifikasikan dan prediksi. Tujuan dari penelitian ini yaitu untuk menganalisis profil siswa terhadap indikator-indikator keterampilan proses sains dalam pembelajaran IPA bagi siswa kelas 2 sekolah dasar. Metode penelitian yang digunakan adalah metode penelitian kualitatif. Teknik pengambilan data yang digunakan yaitu teknik penilaian observasi pembelajaran dan wawancara terhadap guru serta siswa. Teknik analisis data mengguanakan alur dari Miles dan Hubermen (1992) yaitu reduksi data, penyajian data, dan penarikan kesimpulan. Penelitian yang telah dilakukan menghasilkan datar hasil observasi profil siswa terhadap keterampilan proses sains menunjukkan sebagian besar siswa kelas 2 dalam tahap berkembang. Jadi, keterampilan proses sains di sekolah dasar yang masih rendah harus ditingkatkan untuk memperbaiki kualitas pembelajaran IPA khususnya meningkatkan keterampilan proses sains pada siswa.
