Abstract

One effort to reduce the use of inorganic fertilizer is by using organic fertilizer using manure or rice husk charcoal. The research used chicken manure with 3 levels: A0 = 0 kg/plot (0 ton/ha), A1 = 3.75 kg/plot (10 tons/ha), A2 = 7.5 kg/plot (20 tons/ha), A3 = 11.25 kg/plot (30 tons/ha). The second factor, husk charcoal with 3 levels: S0 = 0 kg/plot (0 ton/ha), S1 = 1.9 kg/plot (5 tons/ha), S2 = 3.8 kg/plot (10 tons/ha), S3 = 5.7 kg/plot (15 tons/ha). The results showed that treatment with a dose of chicken manure at 7.5 kg/plot significantly increased leaf length, tuber wet weight per plant, tuber wet weight per plot, tuber dry weight per plant, tuber dry weight per plot, root volume, soil pH. , soil CEC, soil C-organic content, but had no significant effect on the number of bulbs and Si uptake of shallot plants. The activated charcoal dose treatment had no significant effect on leaf length, number of tubers, wet weight of tubers per plant, wet weight of tubers per plot, dry weight of tubers per plant, dry weight of tubers per plot and root volume. The interaction between the dose of chicken manure and husk charcoal had no significant effect on all parameters observed, and had no significant effect on the availability of silica in paddy fields.

Abstract

Coconut (Cocos nucifera L.) known by many as the "tree of life is a leading agricultural commodity in North Sulawesi. Coconut is one of the most significant palm crops for both commercial and subsistence use worldwide. Airmadidi District has the potential for plantation land, especially coconut, which is indicated by the area of ??coconut plantation land in Airmadidi in 2021 of 3,373.13 Ha. This research aims to produce spatial mapping of coconut plantation in Airmadidi District using visual interpretation techniques; and to determine the area of ??coconut plantations in Airmadidi District. Visual interpretation method using on screen classification of satelite imagery SPOT 2022 obtained from SAS Planet.  Images were digitized with a geographic information system using ArcGIS 10.8.2 software. The results of the visual interpretation show a map of the distribution of coconut plantations spread across all villages in Airmadidi District, North Minahasa Regency. The total area of coconut plantations in Airmadidi District is 3 023 Ha. Tanggari village has the largest spread of coconut plantations, namely 870,460 Ha, while Sarongsong Satu village has the smallest area, only 2.24 Ha. There was a decrease in the area of coconut plantation during the period of three year which was 305,51 Ha.  The decline in the area of coconut plantations in North Sulawesi, especially in Airmadidi District, is thought to be caused by the conversion of coconut plantation land into residential or industrial areas.

Abstract

In order to accelerate the development of the tourism sector, the Indonesian government has designated five tourist destinations in Indonesia as super priority tourist destinations, one of which is East Likupang of North Minahasa Regency in North Sulawesi Province. Paal Beach is one of the main tourist attractions in East Likupang. Even though the beach is very beautiful and the access to it is very good, the number of visits is still far below it's carrying capacity. This research aims to identify appropriate development strategies for the Paal Beach tourist destination to attract more visitors. The analytical tool used is SWOT analysis. The research results show that various external factors are very supportive for the development of Paal Beach.  However, the beach still has various weaknesses that could make it unattractive for some people to visit.   The main identified weaknesses are related to the lack of adequate infrastuctures and supporting facilities So, the main strategy should be to prioritize improving these infrastuctures and supporting facilities. If infrastuctures and supporting facilities are improved, then this area has great potential to be able to take advantage of the existing external factors identified as opportunities, especially with the designation of East Likupang as one of the super priority tourist destinations in Indonesia.

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

Downy mildew is a significant disease of corn plants caused by the pathogenic fungus Peronosclerospora maydis, with attack rates reaching 95%. The application of slow-release fertilizer based on corn cob biochar is expected to increase the resistance of corn plants. Similarly, Bacillus sp. and Pseudomonas sp. are known as antagonistic microorganisms. Bacteria can produce antibiotic compounds that hydrolyze fungal cell walls, siderophores, and other antibiotic properties that inhibit pathogen growth. This study aims to determine the morphological characteristics of downy mildew-infected corn on biochar-applied land. Treatments were arranged factorially in a Factorial Randomized Block Design repeated four times. The treatment was the application of slow-release fertilizer from biochar mixed with NPK fertilizer, namely control, slow-release fertilizer, slow-release fertilizer + cow urine, and slow-release fertilizer + cow urine + bacteria (Azobacter and Bacillus). The results showed that slow-release fertilizer gave the best growth to both normal and downy mildew-affected maize plants. The stomata of typical corn leaves were more open with regular vascular bundles, while those affected by downy mildew had more closed and irregular stomata. The chlorophyll content index in downy mildew-affected maize can also improve by applying biochar-based slow-release fertilizer.
