Abstract

The research was done at the period of August 2001 until September 2002 with location in Jambu, Kepuharjo Village, Cangkringan Sub district, Sleman regency, Daerah Istemewa Yogyakarta province. The purpose of these research to detect the increasing production of Arabica Coffee tree and the economic value from the using faces and urine of dairy cow which have been proceeded being complex organic fertilizer. The research method use “on farm research” with involved farmer groups “Dadi Makmur” that has obtained arabica coffee tree since 1994 and care dairy cow with the property between 3-7 dairy cow/person. In those location has been occur the good integration between the arabica coffee trees with dairy cow livestock. In arabica coffe farm, the farmer use stale waste which in the form of faces and urine that has proceeded being organic fertilizer to fertilize their plantation in order to the producing coffee is called organic coffee. In this research is put complex organic fertilizer to arabica coffee tree in dosages 5kg/tree, 10 kg/tree and as a control is not put fertilizer. The research result indicate that the using fertilizer for 10 kg/tree has very real influence to the amount of unproduce coffee production with increasing product are 46,56 % and give the economic value that is relative bigger when compared with using fertilize 5kg/tree and without fertilize giving (control).   Key words :   Economic value, integration of coffee tree-dairy cow, organic fertilizer

Abstract

The 2018 earthquake that shook the city of Palu and surrounding areas with the power of 7.4 MW triggered liquefaction in several locations. Earthquakes and liquefaction that occurred caused damage to Gumbasa’s irrigation canals and some paddy fields. This study was conducted at three points in the paddy fields which 2 points located in the Soulowe village and Sidera village, District of Dolo and one is located in the Lolu village, District of Biromaru. This study aims to determine the infiltration rate in the residents’s paddy fields which have not been planted with paddy for a long time. This is because until the data retrieval performed, Gumbasa irrigation network has not functioned and still under repair. Data were collected using a Double Ring Infiltrometer measuring instrument. The results obtained from this study for constant infiltration rate of BGKn 38 = 1.27 cm/hour, BGKn 42 = 1.10 cm/hour and BGKn 51  = 0.75 cm/hour, which all three are classified as a rather slow with a constant infiltration rate ranging from 0.5 to 2 cm/hour. For the difference in fc values, BGKn 38 and BGKn 42 at 0.17 cm/hour and BGKn 42 and BGKn 51 at 0.35 cm/hour, so that BGKn 38 and BGKn 51 is 0.52 cm/hour. Meanwhile, the value of the difference f0 from the three points is BGKn 38 with BGKn 42 at 3.82 cm/hour and BGKn 42 with BGKn 51 at 4.43 cm/hour, and BGKn 38 with BGKn 51 is 0.61 cm/hour.

Abstract

Penelitian ini bertujuan untuk mengidentifikasi pohon pakan orangutan di Laboratorium Alam Hutan Gambut (LAHG) yang  berlokasi di utara Taman Nasional Sebangau dengan luas 50.000 ha. Metode yang digunakan yaitu  Point Centered Quarter Method. Jumlah titik cuplikan yang didapat yaitu 25 titik yaitu 10 titik pada transek 0 Secret Barat, 5 titik masing-masing pada transek 0.4 Barat, transek 0.8 Barat dan transek 1.3 Timur dengan jarak masing-masing titik cuplikan yaitu ± 50 meter. Hasil pengamatan ditemukan 54 jenis dari 22 famili, INP tertinggi pada Transek 0 Secret Barat yaitu Bintan untuk tingkat pohon dan  tiang,  Manggis Hutan untuk tingkat pancang.  Jangkang Kuning untuk tingkat pohon pada transek 0.4 Barat, tingkat tiang Pupu Palanduk dan tingkat pancang  Bintan. Transek 0.8 Barat pada tingkat pohon Jinjit, tingkat tiang Tabaras Akar Tinggi dan tingkat pancang Mahadarah Daun Besar. Transek 1.3 Timur pohon Jangkang Kuning, tingkat tiang Jambu Burung Kecil  dan tingkat pancang Mahadarah Daun Kecil. Hasil rata-rata indeks keanekaragaman (H’) tergolong sedang dengan nilai 2,37. Lima jenis pohon pakan yang banyak ditemukan adalah Bintan, Jangkang kuning, Manggis hutan, Pisang-pisang besar dan Malam-malam.

Abstract

This research aims to determine the nest density and population of orangutans and the characteristics of orangutan nests in the Lapak Jaru Grand Forest Park (Tahura), Gunung Mas Regency, Central Kalimantan Province. The method used is strip transect, namely by making a path 1000 m long and 20 m wide on each side of the path and a total of 10 lanes. The calculation results of the average density of orangutan nests at the research location were 30.99 nests/km2 and the Orangutan population is estimated at 29.36 Orangutan individuals. The type of tree where most nests are found is Merawan (Silver sp), Meranti (Shorea sp), and Bumps/Bleeding (Santiria corferta) and based on the most dominant family is the Dipterocarpaceae family. The height of the tree where orangutans nest is 11-15 m with a percentage of 21.67%. The most commonly found diameter of nesting trees is 11-20 cm in diameter with a percentage of 64.67%. The nest height most preferred by orangutans is 16-20 m with a percentage of 28.30%. The most frequently found orangutan nest class is class 3 with a percentage of 35.85% and class 4 with a percentage of 33.96%, and the most frequently found orangutan nest position in the research location is position 2 with a percentage of 37.74%.

Abstract

Limited hydrological information in the form of discharge data on a river or watershed can hinder the process of developing water resources in the area. Based on discharge data recorded at the Sidoan Weir, site in Parigi Moutong Regency, the river has the potential to be used for various purposes, such as irrigation, micro-hydro power plants, raw water, and thus. This study aims to determine the similarity between measured discharge data and calculated discharge data on the Sidoan River, as well as to determine the reliable discharge on the Sidoan River. The data used in this study are climatological data, rainfall data, and discharge data (2011-2020), including a map of the Sidoan watershed. Evapotranspiration analysis was performed using the Modified Penman Method. Measured discharge data was used to determine the similarity with calculated discharge, which was analyzed using the F.J. Mock Method. The Flow Duration Curve (FDC) method was used to analyze the amount of reliable discharge. The results of the study show that the average evapotranspiration value ranges from 100 to 150 mm/month. The parameters used in the water availability analysis with the F.J. Mock method were watershed parameters optimized with a correlation coefficient between measured and calculated discharge of 0.78. The results of the study show that the RMSE values before and after optimization of the watershed parameters are 4.16 and 2.76, respectively. The calculation validation was performed using Mean Absolute Error (MAE). The FDC results show that the 80% - 90% reliable discharge is 0.251 m3/second - 0.150 m3/second, while the 50% reliable discharge is 0.860 m3/second. These results can provide an overview of water availability that can be used for water resource development and management
