The effect of Altitude on the Characteristics of Arabica Coffee Fruits and Beans (Coffea arabica L.) in Tarutung District, North Sumatera
No full textArabica coffee (Coffea arabica L.) is a type of coffee that is widely consumed by most people in the world because it provides many health benefits. The altitude of the place has a great influence on the size of the fruit and Arabica coffee beans. This research was conducted in Tarutung District, North Tapanuli Regency. This study aims to determine the effect of altitude on fruit size and Arabica coffee beans. This research was conducted from April 2024 to October 2024. This research used the simple linear equation method on Arabica coffee fruit and beans on several lands with different altitudes in Tarutung District, North Tapanuli Regency. On each land, 10 Arabica coffee fruits samples were taken using descriptive method and purposive sampling technique, coffee fruit and beans were measured using a caliper and analytical scales. The results showed that the altitude of the place had effect on the parameters of fruit diameter, seed diameter, fruith length, seed length, and seed dry weight.63 PagesSkripsi Sarjan
Evaluasi Lahan Kopi Arabika Umur 11-15 Tahun di Kecamatan Tarutung
No full textArabica coffee yield could be determined by the age of the plant and land characteristics therefore it need for land evaluation. This study was aimed to determine the actual and potential land suitable classes for Arabica coffee and to obtain the relationship the land characteristics with Arabica coffee yield at aged from 11 to 15 years. This study was conducted in Tarutung subdistrict, North Tapanuli District from November 2021 to February 2022. This study was conducted using a survey method and sampling with purposive sampling technique. An overlay was made based on the Maps of Altitude, Soil Type, Slope and obtained 19 Land Map Units/LMU. The data from the LMU was matched with a characteristics table of Arabica coffee and then a regression test was performed on the yield using the SPSS v.25 software. The results showed that the actual suitable classes for several LMU (LMU 2, 3, 4 and 5) were classified as marginal suitable with the limiting factors, which were dominated by water availability, rooting condition, and nutrient retention. After efforts to improve the LMU, it were still classified as marginal suitable, but the limiting factor had change to be water availability and rooting condition. In the other LMU (LMU 1) found the actual and potential suitable classes were classified as not suitable with the limiting factor of the rooting condition. Land characteristics not significant on the weight of 100 beans and yield ha-1 of arabica coffee aged from 11 to 15 year.41 HalamanSkripsi Sarjan

Kandungan Logam Berat Pb pada Kol dan Tomat di Beberapa Kecamatan Kabupaten Karo
No full textThis research is aims to find
out the content of heavy metals Pb on cabbage leaf and plum tomatoes in three
districts of Karo Regency, those are Simpang empat, Kabanjahe and Tiga Panah
district. The plant analysis have held in the laboratory of oil palm Research
Centre (PPKS), at April-May 2016, using Random Design Group (RAK) factorial
with three replications. The first factor is the type of plants: cabbage leaf and fruit
skins of tomato, the second factor is the distance from the highway, namely the 5
m and 10 m and the third factor is the leaching that is without being washed and
washed with flowing water. The parameters observed are heavy metal Pb content
in the leaves of the plant and fruit skins cabbage tomato plants.
The results showed that the type of plant, the distance from the highway
and the leaching effect on levels of Pb. The levels of Pb on cabbage leaf at a
distance of 5 m and 10 m without washing each 6.19 ppm and 4.79 ppm and with
leaching 4.48 ppm and 3.86 ppm. While the levels of Pb on tomato fruit at a
distance of 5 m and 10 m without leaching 4.01 ppm and 3.10 ppm and with
leaching 3.08 ppm and 2.26 ppm.46 HalamanSkripsi Sarjan
