Soil Moisture Assessment Using Soil Moisture Index (SMI) Method at the Bangelan Coffee Plantation, Malang Regency, East Java

Water is one of the limiting factors in the growth of coffee plants. If plants experience a lack of water, it can inhibit plant growth and, at a critical level, can lead to drought stress and plant damages. The available soil water to plants can be estimated from the level of soil moisture index. The monitoring of soil moisture status can be used in improving the management of coffee plantations. Soil Moisture Index (SMI) is a method that can be used to estimate the level of soil moisture using remote sensing technology using NDVI and LST values. The purpose of this study was to analyze the status and distribution of soil moisture at the coffee plantation; analyze the relationship between vegetation index and soil moisture; and analyzed the relationship between soil moisture status using the SMI method and soil moisture measured in coffee plantations. Results showed that the soil moisture index obtained from Landsat 8 OLI/TIRS image processing had an average value of 0.60. The average soil moisture index at the study site is 1.05. Soil moisture index from the Landsat 8 OLI/TIRS image has a significant positive effect on soil moisture at the study site (y = 7.4996x – 3.4789; R2 = 0.7146**). It is suggested that the SMI method can be used to estimate soil moisture in the coffee plantation.

In general, the land of Lake Sunyayuri, Cimarias Village, Pamulihan District, Sumedang Regency is an area that has the potential to become a tourist spot with an artificial lake, and a panoramic view of the hills surrounding the lake with a beautiful and calming atmosphere. The productivity of Indonesian coffee is still low compared to the potential that can be increased. The need for plantation land, especially coffee, is still lacking. Utilization of abandoned forest areas in areas with coffee potential can still be carried out, including utilizing the Pamulihan Cekdam area. What is the form of the Sumedang Coffee Agrotourism design in utilizing the existing potential into plantation tourism that provides interesting tourist experiences, recreational facilities, and social interaction as well as coffee education for visitors and the community about how to cultivate coffee from nurseries to products that can be enjoyed and provide a source of income for local communities while preserving the environment?

ANALISIS POTENSI SIMPANAN KARBON AGROFORESTRI PERKEBUNAN KOPI ROBUSTA (COFFEA CANEPHORA) DI PEGUNUNGAN ARGOPURO, KABUPATEN BONDOWOSO

Coffee plantation areas have the potential to absorb carbon dioxide in the atmosphere to reduce the greenhouse gas (GHG) emissions. Especially if coffee plantations are developed with forest plants in agroforestry area within forest management patterns. On the other hand, some coffee agroforestry now, are planted with horticultural crops that can reduce carbon sequestration ability to reduce climate change impact. The objectives of the study are to identify the parameters of the abiotic environment and the potential for carbon storage in robusta coffee agroforestry at Argopuro mountains, Bondowoso Regency. Through the calculation of plant biomass and carbon stock, it is potential to approach the amount of carbon uptake in plants to reduce carbon emissions in the atmosphere. Coffee plantation is one area that can increase carbon sequestration in the atmosphere. The results showed that microclimate parameters at robusta coffeeagroforestry at Argopuro mountains in Bondowoso regency i.e. temperature, air humidity, light intensity has average values of 29.2 oC; 54%; and 2166 lux respectively, then an average of soil pH is 6.00. There were some commonly plants founds in robusta coffee plantation i.e mango trees, avocado trees, dadap trees, pine trees, and more banana plants. Total biomass estimation in robusta coffee plantation area is 144,834 tonnes/ha. The identification of carbon stock show that the robusta coffee agroforestry area with ??2000 m2 can contribute to reduce atmospheric carbon emissions by 72.417 tonnes/ha in Argopuro mountains, Maesan District, Bondowoso Regency. Keywords: Argopuro Mountains; Bondowoso; Carbon stock; Coffee agroforestry; Climate Change.

Flower-visiting insects to Coffea arabica flower at different temperatures and the production of the fruit of arabica coffee

Temperature change may affect insect activity, including flower-visiting insects. Flower-visiting insects, particularly pollinators, have an impact on the fruits produced. This research aimed to study the relationships of flower-visiting insects at different temperatures and coffee production. The gauze experiment was carried out on the coffee plantation that consists of two sites, shaded and unshaded. The study involved 30 arabica inflorescences. The number of flower-visiting insects was recorded and captured. The results showed that the diversity of flower-visiting insects was related to the temperature differences. The flower-visiting insect on the unshaded site was more diverse than the shaded site. The formation of peaberries and the productivity of coffee fruit were also different. Peaberry production was lower (6.24 %) while the fruit mass was heavier (0.15±0.096 g/cherry) in unshaded than shaded sites. However, at the unshaded, the percentage of coffee beans defect was 0.56 % greater than the shaded one. According to these findings, more flower-visiting insects lead to the lower peaberry formation, the heavier fruit mass but potentially causing higher defective coffee beans. The increase in temperature due to climate change can be detrimental because these phenomena will increase the number of coffee fruit defects and insect pests.

The characteristics and tourism destination criteria of coffee plantation agritourism

The coffee plantation agritourism (CPA) is one of the new type of tourism destinations in West Java, Indonesia. The application of sustainable agritourism is used as an effort to increase the number of tourists who are interested in nature tourism. At this CPA the number of tourists is still low and has not implemented sustainable agritourism. The puIDRoses of this study is to identify this agritourism’s characteristics that referred to the perception of tourists towards CPA “K Farmers” and the “K Farmers” achievements of the indicators of sustainable tourism destinations. The methodology of the study is case study by a qualitative design. The result of this study showed that the perception of tourists “K Farmers” is in high level with a perception index value of 33, so it can be concluded that the perception of tourists to Coffee Tourism “K Farmers” is “good”. The criteria of sustainable tourism destinations according to the guidelines from the Minister of Tourism Regulation, CPA “K Farmers” has been and is developing with almost all the criteria in the regulation, but there are still criteria that have not been met by “K Farmers”. This research implies that agritourism business owners need to pay attention to sustainable destination guidelines as a reference in developing their business and meeting the adaptation requirements of climate change, tourism asset and attraction records, access for all, crisis and emergency management.

A Study on Economics of Coffee (Coffea arabica) Plantation in Nagaland, India

The present study was conducted for estimating the economics of coffee plantation in Nagaland. Three districts were selected, and 60 respondents were interviewed from the selected districts. Selection of respondents was carried out with the help of snowball sampling method. Snowball sampling method was used due to limitation of secondary data on coffee farmers and the uneven distribution of coffee farmers. The cost of coffee cultivation was estimated by using different cost concepts used in farm management studies. This study revealed that total establishment cost of coffee was Rs. 22,271/- per acre. The gestation period of arabica coffee found as 4 years for the present study, thereafter the maintenance stage begins with an annual maintenance cost of Rs. 17,762/- per acre. Average yield reported in the study area was 229 kg/acre and making a gross income of Rs. 45,868 /- per acre. The net return worked out as Rs 28,106/- per acre / annum. The productivity of coffee was found as lower than the national average, which maybe as a result of poor availability of labour, the plantations are rainfed and organic by default, therefore absence of fertilizer input may attribute to low productivity. The cost as well as the yield was found lower in the marginal category and increased as the plantation size increases, this may be due to the absence of competitiveness and poor technical knowledge on the management of the plantation among the marginal growers. However having a return to scale value of 1.03 and benefit cost ratio of 1.6, it was cleared that the coffee plantation in Nagaland is profitable and can be undertaken in a commercial scale.
