Abstract

ABSTRACTThe objective of this study is to develop Tangkoko - Duasudara Nature Reserves management blocks using Geographic Information Systems approach. The overlaying methods of thematic maps were used to blend land cover, elevation, slope, and distribution of wildlife species. Social data included demographic data in the surrounding area of Tangkoko - Duasudara Nature Reserves. Management block criteria and scoring refer to Peraturan Pemerintah Tentang Tata Hutan dan Penyusunan Rencana Pengelolaan Hutan, Pemanfaatan Hutan dan Penggunaan Kawasan.The result showed that Tangkoko - Duasudara Nature Reserves are divided into three blocks, namely Restoration/Rehabilitation Blocks (1724.29 ha; 23,22%), Jungle Blocks (4.251,41 ha; 57,26%), and Core Blocks (1449,30 ha; 19,52%). Restoration/rehabilitation blocks are spread into five places and physically characterized by moderate slope, medium altitude and low species density. Land cover is dominated by open land and agriculture. Jungle Block are spread into three places and characterized by plane to medium altitude and high species density. Secondary forest is the dominant land cover. The Core Blocks are spread into two places and characterized by steep slopes, high altitude, high species density. The land cover is dominated by secondary forests.

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
