ABSTRACT Paulus, J.M. 2005. Land Productivity, Competition, and Tolerance of Three Sweet Potato Clones Planted as Intercroping with Maize. Eugenia 11 (1): 1-7. A field experiment was conducted in Cikeumeuh Experimental Garden of Food Crop Biotechnology Research Station (BAUTBIO) Bogor to study Land Equivalent Ratio (LER), Competition Ratio (CR), and Stress Tolerance (TOL) of sweet potato and maize. The highest tuber yiled of sweet potato was 16,83 ton ha-[1] gained by CIP-2 at 100 cm planting distance of maize and the highest maize yiled was 4,50 ton ha-1 Cangkuang in intercropping with Cangkung clone. The LER, CR, and TOL, CIP-2 and SQ were suitable for intercrops at all planting distance but Cangkuang was not suitable for intercrops with maize.

Abstract

The Archipelago Capital (IKN) as the new capital is on the island of Kalimantan, replacing Jakarta. The IKN development carries the forest city concept which pays attention to environmentally friendly aspects. This writing aims to apply the International Environmental Organization Program in the model and form transmission mechanism and apply the Law of the Republic of Indonesia Number 32 of 2009 in the model and form the transmission mechanism. The endogenous and exogenous variables required for simultaneous equations are by theory and empirical experience. The model built consists of 16 endogenous variables (G) and 29 predetermined variables. This means that in model (K) there are 45 variables. There are 14 exogenous and 16 endogenous variables, so (M) totals 30 variables. Thus, (K – M) = (G – 1). This means that the model is identified precisely and is suitable for analysis using the Two Stage Least Squares Method. Application of the International Environmental Organization Program, namely establishing the International Eco Green University to function in the field of research, development and preservation of flora, fauna and marine biota endemic to the island of Kalimantan. The application of the Environmental Law is realised starting from the process of providing residential or office infrastructure in the form of condominiums to the technology for processing liquid and solid waste materials into organic materials for agricultural fertiliser, biogas, animal feed and land fisheries. The transmission mechanism is from achieving added value in all business fields to the growth of IKN's Gross Regional Domestic Product.

Abstract

This study aimed to (1) examine the effect of giving PGPR (Plant Growth Promoting Rhizobacteria) to increase soybean growth and production and (2) obtain the best dose of PGPR to increase soybean growth and production. The research was carried out in Tontalete Village, Kema District, North Minahasa Regency, North Sulawesi from June 2021 to October 2021. The field experiment was arranged in a Randomized Block Design (RBD). The treatment tested was the concentration of PGPR, which consisted of  P0 = 0 ml/l (control), P1 = 5 ml/l, P2 = 10 ml/l, P3 = 15 ml/l, and P4 = 20 ml/l. The treatment was repeated three times, so there were 15 experimental units. Parameters observed were: plant height, number of branches, number of pods per plant, percentage of damaged pods per plant, the weight of 100 dry seeds, and seed yield/plot. The data were analyzed using the Analysis of Variance (ANOVA) and continued with the mean difference test using the Least Significant Difference Test (LSD) at the 5% level. The results showed that the application of PGPR affected the growth and yield of soybeans by increasing plant height, the number of pods per plant, and dry seed yield. The highest dry seed yield was achieved at PGPR concentrations of 10 ml/l and 15 ml/l, which were 1.34 g and 127.87 g, equivalent to 1.34 tons ha-1 and 1.28 tons ha-1, respectively.

Abstract

This Zingiberaceae plant is widely used as medicine, including temulawak. Because curcuma (C.xanthorrhiza) is a medicinal plant that has many benefits and includes plants needed in large quantities compared to other medicinal plants. Traditionally rhizomes Temulawak is used to treat stomach ailments, liver disorders, constipation, diarrhea, dysentery, fever, hemorrhoids, hypotriglyceridaemic, and anti-inflammatory. Study about plant Curcuma local ignite still not enough researched so that not yet get information compounds which contained in the local curcuma of North Sulawesi for the development for biopharmaceutical development, mapping in the distribution of plants, ecology, plant conservation and protection to maintain local wisdom. Histochemical Test is a method to determine the content of chemical compounds in a plant tissue qualitative. Testing can be done by adding a special reagent or solution to the incision organ plant and will give color which Specific. Activity study this will test curcumin compound group on local ginger from North Sulawesi by histochemical method. research that done is study non experiment with design descriptive qualitative. The results showed that North Sulawesi local white temulawak powder contained curcumin in a sample with a sample weight of 0.10 g at a sample spotting volume of 20 µl with a sample spotting volume of 2040 nanograms, curcumin levels were <0.10 nanograms/mg. Curcumin biosynthesis is influenced by site conditions, agro-climate, genotype, and plant cultivation.

Abstract

To achieve sustainable and environmentally friendly agriculture, organic-based rice cultivation techniques utilising local resources are gaining popularity. Biosaka, a plant extract solution, functions as an elicitor with the potential to increase plant productivity. This study aimed to analyse: (1) the single effect of Biosaka application time on the growth and production of lowland rice; (2) the single effect of Biosaka concentration on the growth and production of lowland rice; and (3) the interaction between application time and concentration in influencing the growth and production of lowland rice. The study was conducted in Taratara Dua Village, West Tomohon District, Tomohon City, from April to October 2024. This field study used IR-64 rice varieties and a randomised block design with two factors: application time (5, 10, and 15 days) and concentration (0, 30, and 60 ml/15 L). The variables measured included plant height, number of productive tillers, panicle length, and grain yield. The results showed no interaction between the two factors. Although the application time factor did not significantly affect any variables, the Biosaka concentration significantly affected the number of productive tillers, panicle length, the number of filled and empty grains, and the dry grain yield per plot. Interestingly, this study achieved the highest yield in the control treatment (0 ml/L), with a dry grain yield of 6.19 kg per plot. This indicates that the Biosaka application, at the concentration tested, did not increase rice yield in this study.

Abstract

Coconut (Cocos nucifera L.) is a highly valued agricultural commodity in Indonesia. The Salak Dwarf variety is particularly popular among farmers due to its short harvest period and high productivity. To further enhance its potential, the use of Plant Growth-Promoting Rhizobacteria (PGPR) is being explored. PGPR are beneficial microorganisms that act as biofertilizers, improving plant growth through mechanisms such as nitrogen fixation, phosphate solubilization, and the production of growth hormones. This study aimed to evaluate the effectiveness of PGPR derived from bamboo roots on the growth of Salak Dwarf coconut seedlings. The research also sought to determine the optimal PGPR concentration for maximizing seedling growth. The experiment was conducted at the BSIP Tanaman Palma in North Sulawesi from January to May 2024. A Randomised Block Design (RBD) was used, with six treatments and three replications, totaling 18 experimental units. The treatments included a control (P0) with no PGPR and five PGPR concentrations (30, 60, 90, 120, and 150 ml/L). The key growth variables measured were plant height, leaf number, pseudo-stem girth, and leaf width. The results showed that bamboo root PGPR significantly influenced all measured growth parameters. The study concluded that the most effective concentration for promoting the growth of Salak Dwarf coconut seedlings was 60 mL/L. This finding highlights the potential of bamboo root PGPR as a natural, sustainable biostimulant to improve coconut cultivation.
