The yard plays an important role in meeting the needs of the community, namely by planting in the yard of the house, especially to meet the needs of the household, especially in meeting the needs of the family's home food, can be planted with food crops such as fruit, vegetables, tubers, spices, etc. The aim of the research was to study the types of food plants found and to know the abundance index and dominance index of food plants found in Mandikapau Barat Village. The method of this research is to determine the area of the yard, take samples of the yard, identify the types of food plant categories (fruits, vegetables, tubers, and spices), and calculate the abundance index and dominance index of these food plants. Results Food plants found totaled 25 families 32 genera 40 species (27 fruits; 5 vegetables; 2 tubers; 6 spices). The highest relative abundance index of the three locations was in the category of spices, bulbs, fruits, vegetables with a value of (28%; 6%; 5%; 4%) with galangal, cassava, papaya and cayenne pepper plants. The average dominance index shows a value of 0.131 which is included in the low category.KEYWORDS: Mandikapau; Kabupaten Banjar; food plant; dominance index
Telah dilakukan penelitian tentang Pola Longsoran di Daerah Rawan Longsor Berdasarkan Nilai Resistivitas Bumi di Desa Sungai Langsat, Kecamatan Simpang Empat, Kabupaten Banjar. Penelitian ini bertujuan untuk mengetahui litologi berdasarkan nilai resistivitas bumi di daerah yang diperkirakan rawan longsor dan menentukan pola longsoran menggunakan metode tahanan jenis. Konfigurasi elektroda yang dipakai menggunakan metode Wenner-Schlumberger (1D). Data dari hasil pengolahan program Progress digunakan untuk menentukan litologi. Hasil litologi tersebut dibuat penampang dua dimensi dan tiga dimensi menggunakan program Surfer sehingga dapat ditentukan arah serta pola longsoran pada daerah pengukuran. Nilai tahanan jenis tanah/batuan antara 6,82 – 145,35 Ωm diduga sebagai zona lemah/pelapukan yaitu lapisan lempung sedangkan nilai tahanan jenis tanah/batuan antara 145,35 – 538,33 Ωm diperkirakan sebagai zona lapisan keras yaitu tanah endapan berpasir. Pola longsoran untuk tanah endapan berpasir diperkiraan pada kedalalaman antara 10 – 30 m, ke arah koordinat X = 285740 mT dan Y = 9635900 mS. Untuk lapisan lempung, longsoran diperkirakan terletak pada kedalaman antara 4 – 6 m, ke arah koordinat X = 285770 mT dan Y = 9635900 mS. Besarnya sudut kemiringan lereng yang terbentuk adalah 16,26o. Pola longsoran pada daerah tersebut adalah pola longsoran translasi dan pola rayapan tanah.
Limau kuit is a typical orange from South Kalimantan which is used by the Banjar people in some certain local culinary. This experiment is explorative research that aims to determine the yield of essential oils obtained by hydrosteam distillation method with ball condenser (type of Allihn) cooling, to determine the characterization of the oil comprising specific gravity, refractive index, optical ratation, solubility in alcohol, the composition of using GC-MS. The leaves of limau kuit were air-dried for one week to decrease the water content and then were cut into smaller pieces about 5 mm in size. A 2.050 grams of the sample lay into the tray of the distillation kettle which was filled with adequate water. The distillation was carried out for about 6 hours and 50-60oC in temperature. The results showed that the performed extraction yielded 0.59%-(v/w) or 0.52%-(w/w) of oils. The oil values of specifie graviry, refractive index, optical ratation, and solubility in alcohol 90% were 0.8285, 1.472, (-)1.90, and 1:4 respectively. The CG-MS analysis showed 31 chemical compounds of the oils and these were five the dominants: γ-terpinene (24,19%), followed by prehnitene (18,26%), (+)-4-carene (8,53%), β-cis-ocymene (7,20%), and β-pinene (5,46%) respectively.
Plant diversity indicates the existence of various variations in shape, color, body structure, and the amount contained in an area or ecosystem. The purpose of this study was to describe the types and number of index values for the diversity of types of flower plant in the yards of the residents of Mandikapau Barat Village. The method of this research was to determine the location by means of a survey, determine the area of the yard, take samples by purposive sampling technique, identify the types of flower plant using plant morphology book, and conduct data analysis by calculating the importance value index, species diversity index, dominance index, and abundance index. type. The results of this study found that there were 60 types of flower plant with an average abundance of 1087 ind/m² and 34 famili; RT 1 (26 species with an average abundance of 317 ind/m² and 20 famili); in RT 2 (26 species with an average abundance of 318 ind/m² and 22 famili); and in RT 3 (49 species with an average abundance of 452 ind/m² and 30 famili). The types of flower plant that were mostly found in RT 1 were dahlia flowers (Zinnia elegans L.) 16.72%; in RT 2, namely dahlia flowers (Zinnia elegans L.) 21.70%; and in RT 3, namely linjuang (Cordyline fruticosa L.) 14.38%. Plant in the tree ornamental plant category were 1.7%, leaf ornamental plant were 13.3%, and flower ornamental plant were 85%. The overall value of the diversity index of flower plant is 2.71, which is in the medium category. The overall value of the domination index of 0.1 for flowering plant is in the low category. The overall value of the abundance index of types of flower plant is 0.78, belonging to the high category. The overall value of the important value index of 0.67% for flowering plant is classified in the high category.
Aliran permukaan merupakan air yang mengalir di permukaan tanah dan merupakan curah hujan yang mengalir ke sungai atau saluran danau dan laut. Di daerah beriklim basah bentuk aliran yang mengalir dikenal sebagai aliran permukaan. Debit adalah laju aliran air (dalam bentuk volume air) yang melewati suatu penampang melintang sungai persatuan waktu. Penelitian ini dilakukan di Catchment Area Sungai Hauran karena dapat dikatakan sebagai daerah tangkapan air bagian hulu dari Sub Sub DAS Apukan, Sub DAS Banyu Hirang, DAS Maluka. Analisis Aliran permukaan dan debit puncak dapat menggunakan Agricultural Non Point Source Pollution Model (AGNPS). Pengolahan data menggunakan model AGNPS diperoleh nilai tertinggi aliran permukaan pada sebesar 7,366 mm. Nilai aliran permukaan yang tinggi terdapat pada daerah tangkapan hulu, hal ini di pengaruhi oleh tekstur tanah dan tutupan lahan pada area tersebut. Besar nilai debit puncak pada outlet keluaran model AGNPS sebesar 3,063 m3/s , sedangkan nilai debit puncak tertinggi yaitu sebesar 3,390 m3/s
