Abstract

The research aims to observe the influence of harvesting time on the change of calcium oxalate (CaOx) content and crystal density in Porang corms. The corms were harvested at different times, i.e., (1) two weeks before the plants shed (R0-1), (2) when the plants shed (R0), and (3) two weeks after the plants shed (R0+1). CaOx was obtained using the modified extracting method. Microscopic observations were obtained from the slices of the edge and center part of porang corms. Parameter observed including CaOx content, corm weight, shape, and density of CaOx crystal. CaOx content and crystal density in corms were analyzed using One way ANOVA. If the results are significant, it will be followed by Tukey Test α 0.05. In the meantime, the relation between CaOx content and corm weight was analyzed using Correlation Test Bivariate. The results showed that CaOx content was relatively higher in porang corms, i.e., 15.98 ± 0.60g/100g. On the other hand, the increasing of CaOx content might improve corm weight. The total density of druse, styloid, and prism crystal was pretty high in corms obtained when the plants shed compared to another harvest time, i.e., 1,494 ± 286; 31,280 ± 17,406 and 6,256 ± 1,533 crystals/cm2 . Raphide crystal density, by contrast, increased in corms obtained after the plants shed, i.e.,1,656 ± 368 crystals/cm2 . Total CaOx crystal density in the edge parts of corms harvested when the plants shed was proportionately higher than in the other harvest times, i.e., 12,292 ± 4,687.89 crystals/cm2 . In contrast, CaOx crystal densities in the center parts of corms were not much different at three harvesting times. The density of druse and prism crystals was somewhat higher in the center part of corms than in the edge parts. In opposition to, the density of raphide and styloid crystals was fairly higher in the edge part of corms than it was in the center parts. However, only raphide crystal density found in the edge and center part of corms was significantly affected by harvest time from all these results.

Abstract

Kalimantan Utara merupakan salah satu provinsi yang berbatasan langsung dengan Negara Malaysia perlu didukung untuk dapat berkembang sehingga masyarakatnya tidak tergantung dengan produk-produk pertanian dari daerah Negara lain. Salah satu hal yang bisa dilakukan guna mendukung hal tersebut adalah dengan menerapkan program pertanian terpadu. Desa batu kajang merupakan salah satu desa terluar di wilayah Kalimantan Utara dan sebagian besar masyarakatnya bermata pencaharian sebagai petani tanaman hortikultura, permasalahan yang ada di desa Batu Kajang yaitu masyarakatnya belum banyak yang memiliki usaha sampingan lain untuk menunjang ekonomi keluarga sehingga masyarakat disana hanya bergantung pada pendapatan hasil panen yang dijual kepasar. Kegiatan pengabdian kepada masyarakat ini dilaksanakan di Desa Batu Kajang Kabupaten Malinau Provinsi Kalimantan Utara. Mekanisme kegiatan dibagi kedalam beberapa tahapan yaitu survei, sosialisasi, pelatihan dan evaluasi kegiatan. Kegiatan pelatihan merupakan kegiatan puncak dari PKM yaitu bimbingan teknis kepada masyarakat mengenai pembuatan instalasi hidroponik dan pembuatan kolam terpal untuk ikan lele. Tahapan pelatihan terdiri dari beberapa tahapan diantaranya pembuatan instalasi hidroponik, Kegiatan pengabdian masyarakat berjalan dengan baik ditunjukkan dengan antuasisme masyarakat desa batu kajang yang sangat besar dalam mengikuti pelatihan tersebut. Budidaya tanaman secara hidroponik dan ternak lele merupakan salah satu solusi terbaik sebagai usaha sampingan dalam meningkatkan pendapatan ekonomi keluarga.

Abstract

Trichomes play a role in protecting plants from herbivores and pathogens, and their formation can be influenced by nutrient availability and environmental factors. This study examined the effect of liquid organic fertilizer (POC) on the development of leaf trichomes in cayenne pepper (Capsicum frutescens) grown on ultisol soil in Tarakan, Indonesia. The experiment used a completely randomized design with seven fertilization treatments: control (P0), NPK (P1), and POC at concentrations of 5–15 g/L (P2–P6), each replicated four times. Leaf samples collected 45 days after transplanting were cleared, stained, and observed microscopically. Several types of trichomes were identified, with non-glandular forms observed more frequently than glandular ones, mainly located along the abaxial midrib and veins. Variation in trichome number and form appeared to increase in plants treated with higher POC concentrations (10–15 g/L). Occasional fungal structures were noted on some leaf surfaces, coinciding with the presence of glandular trichomes. These observations suggest that POC application may influence trichome development in cayenne pepper under field conditions, providing preliminary morphological information relevant to organic fertilization practices on marginal soils.

Abstract

Intercropping is acknowledged as an effective agricultural intensification strategy for limited land. Planting time is an important factor in intercropping systems because it may intensify canopy overlap and shading, particularly because both crops rely on the C3 photosynthetic pathway, potentially reducing growth and yield. This study examined the effect of different planting times for cucumber (Cucumis sativus L.) and peanut (Arachis hypogaea L.). The study was conducted from October 2023 to February 2024 with a one-factor randomized block design. Five treatments were applied: simultaneous planting and cucumber planting at 1, 2, 3, and 4 weeks after peanuts, each replicated five times. Several data were analyzed using analysis of variance (F-test), followed by Tukey’s HSD test at the 5% significance level. This study confirms that differences in planting time between cucumbers and peanuts significantly affect soil macronutrient dynamics, growth and production, and land use efficiency. Soil macronutrient analysis showed that simultaneous planting (P1) resulted the highest soil nitrogen increase (0.38%). However, this treatment also caused a reduction in phosphorus to 15.15 mg per 100 g of soil and potassium to 13.48 mg per 100 g of soil. In contrast, excessive delay (P5) caused nitrogen to drop to 0.11% and phosphorus to decline to 14.19 mg per 100 g soil, despite potassium remaining relatively high (17.87 mg per 100 g of soil). Simultaneous planting produced the highest vegetative growth of cucumber, with an average of 40.68 leaves per plant, the greatest fruit length (22.16 cm), individual fruit weight (414.55 g), and total fruit weight per plant (2498.39 g). Delaying cucumber planting resulted in the lowest value of 828.45 g in P5. The highest pod weight was recorded in P1 at 62.46 g per plant. In contrast, planting cucumbers one week after peanuts (P2) resulted in the lowest peanut yield, at only 47.14 g per plant. All treatments achieved LER values greater than 1, confirming the superiority of intercropping over monoculture. The highest LER was obtained in P1 (1.61). In conclusion, simultaneous planting of cucumbers and peanuts provides the most optimal balance between soil nutrient utilization, crop growth, yield, and land use efficiency. Therefore, synchronized planting time is a key management strategy for improving productivity and sustainability in cucumber–peanut intercropping systems under limited land conditions.

Abstract

This study evaluated the effect of additives in papaya leaf–based botanical pesticides on the vegetative growth of water spinach (Ipomoea reptans Poir). The experiment was arranged using a Randomized Complete Block Design (RCBD) with five treatments and five replications: P0 (control), P1 (papaya leaves), P2 (papaya leaves + garlic), P3 (papaya leaves + lemongrass), and P4 (papaya leaves + soursop leaves). Observed parameters included plant height, root length, number of leaves, and fresh weight. Data were analyzed using analysis of variance (ANOVA), Duncan’s Multiple Range Test (DMRT) at 5%, correlation, and multiple linear regression analyses. The treatments significantly affected most growth parameters. P3 (papaya leaves + lemongrass) produced the best performance, with plant height of 24.35 cm, root length of 22.58 cm, approximately 18 leaves, and fresh weight of 14 g. Correlation analysis showed strong positive relationships between plant height and number of leaves (r = 0.890), and between root length and fresh weight (r = 0.764). Regression analysis identified number of leaves as the strongest predictor of fresh weight (β = 1.015), followed by root length (β = 0.528), whereas plant height showed a negative effect (β = −0.891). Overall, the addition of lemongrass to papaya leaf–based botanical pesticides enhanced vegetative growth and biomass accumulation in water spinach plants.
