Abstract

Chili (Capsicum annum L.) is a type of vegetable that is widely cultivated by farmers in several regions in Indonesia. The productivity of chili plants has decreased due to the excessive use of inorganic fertilizers. Fertilization using liquid organic fertilizer from cow dung is one effort to minimize the use of inorganic fertilizers. This study aims to examine the application of POC nutrition from cow dung in a wick hydroponic fertigation system for the development of chili plants. Observations were made to determine the water needs of plants (evapotranspiration) and the development of hydroponic chili plants with different concentrations of nutrients from liquid organic fertilizer from cow dung. Optimal treatment of giving nutrient concentrations of cow dung liquid organic fertilizer to plant water needs or evapotranspiration and development of chili plants is found at a concentration of 1,000 ppm (P3).

Abstract

Information technology is necessary today, especially to present information on land planted with horticultural crops in an area. The need to obtain fast, precise, and accurate information with the existence of an internet network via smartphones has proven to be very helpful in presenting information to local governments and buyers of horticultural products in obtaining products that can be traded to the public. Often the difficulties that occur in several agricultural areas, the information available is only in the form of location data tables and the exact location is unknown. The problem is that this information is not yet available in some areas. Therefore this study aims to create a web-based information system by compiling, storing and showing information about existing horticultural plants by taking a case example in Girian District, Bitung City, North Sulawesi Province. Web-based information is created by combining the information using a geographic information system (GIS) that displays descriptive text, tables, and images based on spatial location. The results of this study are expected to be useful for farmers in Girian District and local governments in planning and evaluating horticultural farming more easily. The research was conducted by building a web using the Windows 10 pro operating system platform, ArcGIS 10.8 software, Google Earth, Microsoft Word, and XML as a web server, and WordPress 5.4.1 as a content management system. Websites that have been built are tested for performance with gtmatrix with good results. The website that has been built can provide information related to horticultural crops in Girian District, Bitung City, especially information about Girian District and also the location of horticultural crops in Girian District, Bitung City.

Abstract

Indonesia has a variety of medicinal plants that are efficacious for preventing or treating various diseases. Each region has unique medicinal plants, such as in North Sulawesi, there are many medicinal plants with local names of "Jarak" (Jatropha curcas), "Jarak Merah" (Jatropha multifida), "Miana" (Coleus Scutellarioide), and "Sesewanua" (Clerodendron Squmatum Vahl). This research applies the Convolutional Neural Network (CNN) method to identify the types of medicinal plants of North Sulawesi based on leaf images. Data was collected directly by taking photos of medicinal plant leaves and then using the augmentation process to increase the data. The first stage is conducting training and validation processes using 10-fold cross-validation, resulting in 10 classification models. Evaluation results show that the lowest validation accuracy of 98.4% was obtained from fold-4, and the highest was 100% from fold-2. The third stage was to run the testing process using new data. The results showed that the worst model produced a test accuracy of 80.91% while the best model produced an accuracy of 87.73% which means that the identification model is quite good and stable in classifying types of medicinal plants based on its leaf images. The final stage is to develop a web-based system to deploy the best model so people can use it in real-time

Abstract

This research is aimed to study the pyrolysis and distillation processes of making liquid smoke from coconut shell related to the influence of time and number of raw materials to improve the efficiency of pyrolysis and distillation equipment. This study used an experimental method where the temperature in tube was set at 90° C and after 45 minutes it was maintained at 90° C and then lowered to 75° C. The observation period of the pyrolysis process was carried out every 30 minutes for 8 hours with 3 repetitions, while the distillation process was carried out every 45 minutes with 4 repetitions. The results of the pyrolysis process showed that the steam temperature and pyrolysis time had a relationship to the volume, yield, density and color of the liquid smoke. The average of temperature is 109.58°C gives average result of 6315 ml in volume, yield 21.60%, density 1.027 g/ml and the color is thick black. In the process of distillation, the temperature of steam in distillation affects the result. The temperature of 90°C of liquid smoke comes out quickly and a lot with a total volume of distillation 770 ml and a yellow-brown color. The temperature of 75°C of liquid smoke comes out slowly and the liquid smoke results slightly with a total volume of distillation 293 ml and a yellowish clear color. The color of liquid smoke using laboratory-scale distillation equipment is different from using a distillation tube tool, so it must be re-distilled to get a clearer color

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.
