Abstract

This study aims to describe the agroforestry patterns implemented by the farmers of Wanga Village, East Motoling District, South Minahasa Regency, in this study the method used was a survey method and the determination of respondents was carried out by purposive sampling. The criteria for respondents in this study were farmers who were born and live in Wanga Village and have land managed with an agroforestry system. The results showed that the agroforestry patterns applied by the farmers in Wanga Village were agrisilviculture, agrosilvofishery, and agrosilvopastura. Based on the number of respondents who applied it, the pattern of agroforestry that was most prevalent in the study locations was agrisilviculture with 27 respondents, while agrosilvofishery was only 2 respondents and agrosilvopastura. The results showed that the agroforestry patterns applied by the farmers in Wanga Village were agrisilviculture, agrosilvofishery, and agrosilvopastura. Based on the number of respondents and the area of ​​land that applies the agroforestry pattern, the most common pattern in the research location is agrisilviculture with 27 respondents with a land area of ​​42 ha, while agrosilvofisheri is only 2 respondents with a land area of ​​3 ha and agrosilvopastura is only 1 respondent with a land area of ​​1 ha . The cropping pattern applied to each crop on the entire farmer's land is a random pattern, regular pattern and group pattern with a total of 26 species. plant. In the agrosilvofishery, the types of fish that are kept are Oreochromis niloticus, Oreochromis mossambicus, Cyprinus carpio, and ornamental fish. The type of livestock kept on agrosilvopastura land is pigs. was only 1 respondent. . The cropping pattern applied to each crop on the entire farmer's land is a random pattern, regular pattern and group pattern with a total of 26 species. plant. In the agrosilvofishery, the types of fish that are kept are Oreochromis niloticus, Oreochromis mossambicus, Cyprinus carpio, and ornamental fish.

Keywords: Agroforestry; Agrisilviculture; Agrosilvopasture; Silvofishery Abstrak Penelitian ini bertujuan untuk mendeskripsikan pola agroforestri yang diterapkan oleh petani Desa Wanga Kecamatan Motoling Timur Kabupaten Minahasa Selatan, dalam penelitian ini metode yang digunakan adalah metode survei dan penentuan responden dilakukan dengan purposive sampling. Kriteria responden dalam penelitian ini adalah petani yang lahir dan tinggal di Desa Wanga serta memiliki lahan yang dikelola dengan sistem agroforestry. Hasil penelitian menunjukkan bahwa pola agroforestri yang diterapkan petani di Desa Wanga yaitu agrisilvikultur, agrosilvofishery dan agrosilvopastura. Berdasarkan jumlah responden dan luas lahan yang menerapkan pola agroforestri, maka pola yang paling banyak di lokasi penelitian adalah agrisilvikultur sebanyak 27 reponden dengan luas lahan 42 ha, sedangkan agrosilvofisheri hanya 2 responden dengan luas lahan 3 ha dan agrosilvopastura hanya 1 responden dengan luas lahan 1 ha. Pola tanam yang diterapkan untuk setiap tanaman pada seluruh lahan milik petani adalah pola acak, pola teratur dan pola kelompok dengan total 26 jenis. tanaman. Di lahan agrosilvofishery jenis ikan yang dipelihara adalah Oreochromis niloticus, Oreochromis mossambicus, Cyprinus carpio, dan ikan hias. Jenis ternak yang dipelihara di lahan agrosilvopastura adalah babi. Kata kunci: Agroforestri, Agrisilvikultur, Agrosilvopastura, Silvofisheri

Abstract

Plant chlorophyll plays an important role in the process of photosynthesis. The amount of its content in the leaves can indicate its adaptation to light conditions. This article describes the chlorophyll content of the Dalugha plant in the swamp edge of Lake Kapeta, Siau Island, Sitaro Regency which grows in open light, open-shaded and shaded conditions. This study aims to analyze the differences in the chlorophyll content of Dalugha plant leaves in open, open-shaded, and shaded growing conditions. The method used is an observational method in which the response of plants is observed in a range of conditions provided by nature. Chlorophyll content was observed by measuring the absorbance of plant leaf extracts using a spectrophotometer. The results showed that there were differences in chlorophyll content in the leaves of the Dalugha plant growing under open light, open-shaded, and shaded conditions. In open light conditions it is lower than in open-shaded and shaded conditions. Keywords: Dalugha, Chlorophyll, Light  Abstrak Klorofil tanaman berperan penting dalam proses fotosintesis. Jumlah kandungannya dalam daun bisa menunjukkan adaptasinya terhadap kondisi cahaya. Artikel ini menggambarkan tentang kandungan klorofil tanaman Dalugha di rawa tepi Danau Kapeta, Pulau Siau, Kabupaten Sitaro yang bertumbuh pada kondisi cahaya terbuka, terbuka-ternaungi, dan ternaungi.  Penelitian ini bertujuan untuk untuk menganalisis perbedaan kandungan klorofil daun tanaman Dalugha pada kondisi tempat tumbuh terbuka, terbuka-ternaungi, dan ternaungi. Metode yang digunakan adalah metode observasional dimana respon tanaman diamati pada suatu kisaran kondisi yang diadakan oleh alam. Kandungan klorofil diamati dengan metode pengukuran absorban ekstrak daun tanaman menggunakan spektrofotometer. Hasil penelitian menunjukkan bahwa ada perbedaan kandungan klorofil dalam daun tanaman Dalugha yang bertumbuh pada kondisi cahaya terbuka, terbuka-ternaung, dan ternaung. Pada kondisi cahaya terbuka lebih rendah dibandingkan pada kondisi terbuka-ternaung dan kondisi ternaung. Kata kunci: dalugha, klorofil, cahaya
