Abstract

Abstrak Air irigasi adalah jumlah air yang di aplikasikan ke dalam lahan (pertanian) untuk menunjang proses pertumbuhan tanaman. Mengingat besarnya pemakaian air pada sektor pertanian, sehingga keberadaan sumber air harus tetap dijaga baik secara kuantitas maupun kualitas. Tujuan Penelitian ini adalah untuk mengetahui kualitas air dari Sungai Noan sebagai sumber air irigasi persawahan padi di Desa Molompar Kecamatan Tombatu Timur Kabupaten Minahasa Tenggara. Hasil analisis menunjukkan bahwa nilai Daya Hantar Listrik (DHL), SAR (Sodium Adsorption Ratio), Nitrat (NO3–N),  Fosfat (PO4–P) , dan pH menunjukkan kriteria sangat baik sampai baik sedangkan parameter K menunjukkan kriteria kurang baik atau melebihi standar nilai mutu air irigasi.  Kata kunci : Air irigasi, Standar kualitas air

Abstract

ABSTRACT This study aims to determine the concentration of lead in cabbge plants in Tomohon city.  The results of this study are expected  to provide information to the  public about the amount of lead metal content in cabbage vegetables in Tomohon city. This research was conducted for 3 (three) months, from June to September 2018, the location of sampling in Tomohon City and then analyzed at the Baristand Laboratory. This research was conducted  in a survey using a purporsive sampling  method  by examining samples of cabbage plants that are off  the highway and cabbage that are cultivated far from the highway. Each  location was taken as many as 5 plants.  Pb samples were tested for comparison, wich were analyzed using the Atomic Absorpation Spectrophotometer.  The results of this study indicate that lead concentrations (Pb) in cabbage plantations in Tomohon are detected with concentration values that are still below the standard for heavy metal contamination or are still below the maximum limit. Keywords: Lead, Cabbage

Abstract

The red ginger plant (Zingiber officinale var. rubrum) is one of the commodities needed in various food, beverages, and herbal medicines preparations. So indirectly red ginger is a plant that needs to be cultivated because it has economic value. Knowing the morphological characteristics of the red ginger plant is important for understanding the life cycle, geographical distribution, ecology, evolution, conservation, and definition of plant species. This study determined the morphological characteristics of local red ginger (Zingiber officinale var. rubrum) in the Poso Pesisir sub-district, Central Sulawesi province. The time of the research was conducted from November to December 2022. Research using the method exploration by characterizing the morphological characteristics of red ginger plant aged  10 months. The results obtained a range of plant heights ranging from 43 - 123 cm. The stem length ranges from 27 - 96 cm. Leaf length ranges from 16 - 30 cm. For a wide range of leaves starting from 2,2 - 3 cm. Root length ranges from 12,7 - 47 cm. The weight of rhizomes per clump ranges from 75 - 175 g. From the appearance of details on the outside, the plant is almost uniform throughout and has diversity in the color of the leaves (green, yellowish green, green with yellow spots) and colored stems (dark green, yellowish green, green with yellow spots). This is influenced by the environmental conditions where plants grow.

Abstract

The aim of this study was to test transferability of the predictive models developed in North Sulawesi site using internal data dan external data (Buton island located on the south east coast of the mainland of Sulawesi). Logisitic regression method was used to build the predictive model. Three native palms of Sulawesi namely Pigafetta elata, Areca vestiaria, and Caryota sp were selected in this study. The relationship between environmental variables (e.g. derived from a Geographic Information System (GIS) and Remote Sensing (RS)) and each native palm species occurrence was quantified by the model. Several environmental parameters reflecting land cover, topographic features (elevation, slope and aspect), soil and socio-economic (accessibility) served as predictor variables. Model performance was measured by sensitivity (Sn), specificity (Sp), overall accuracy (S), Kappa statistic and Area Under the Curve (AUC). Predictive models of spatial distribution of the three native palm species were successfully developed using logistic regression method. Using the internal dataset, all models showed greater than 90% overall accuracy at predicting presence or absence which indicates that all models gave good performance. However, using Kappa index, the performance of the logistic regression model was poor. AUC values derived from the ROC procedure showed that the performance of all models was excellent. Nevertheless, when tested on Buton Island, overall prediction accuracy was low. Kappa statistic (0.06 to 0.24) also showed that none of the models performed adequately. It is obvious that predictive ability of the models evaluated with external data from a different island was low. This implies that transferring the models to other regions is not advisable. Unmodelled ecological-relevant processes and algorithmic error are suggested to be the reasons behind the poor transferability of the predictive models.

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.

Analysis Of Irrigation Water Quality For Fields In Treman Village, North Minahasa Kauditan Regency. Ekoton   5. 28-35. This study aims to determine the quality of irrigation water in rice fields in Treman Village, Kauditan District, North Minahasa. This research was conducted for two (2) months, namely from March to April 2023. This research was conducted using purposive sampling method, the sampling technique is Composite. Research samples were taken at three points, namely the Primary Canal, Secondary Canal, and Tertiary Canal. Samples were taken as much as 4500 mL in each Canal, then analyzed at the Manado Industrial Research and Standardization Center Laboratory. The data obtained was analyzed using Bar Chart Statistics. The research shows that the Irrigation Water Quality of Rice Field Areas in Treman Village, Kauditan District, North Minahasa is still classified as very good because it meets the requirements as irrigation water according to Water Quality Of Irrigation based on Ayers & Westcott (1995), and there is no pollution based on Government Regulation No. 22 of 2021 concerning the Implementation of Protection and Management of Irrigation Water.

This study aims to determine the state of the landscape in the Bukit Tetempangan Tourism Object, Mandolang District, Minahasa Regency. This study uses the Digital Elevation Model (DEM) method to obtain the state of the landscape, elevation data, and slope in the Tetempangan Tourism Object area.   Data collection and processing techniques using the ArcGis 10.3 application. The results obtained in the Bukit Tetempangan Tourism Object Area have 3 slope classes, 0 - 25% (somewhat flat) with an area of 17.8 Ha, 25 - 40% (a bit steep) with an area of 5.33 Ha, and >40% (very steep) with an area of 14.87 ha and a height of 568 meters above sea level (masl). The total altitude data obtained can reach 1986 points. Thus, at this location, there must be a conservation application to prevent erosion and landslides.
