Published: June 2021

Abstract
Indonesia is known as an agricultural country for its abundant natural wealth. It has a very strategic geographical position, located in the tropics and having high rainfall. The banking sector has a vital role in economic development. Even though bank business activities do not have a direct impact on the environment, banks can protect the environment through credit financing management. The problem observed in this study is the role of agricultural credit financing in realizing green banking in Indonesia. This research uses a normative juridical method supported by a literature review. The results show that the agricultural sector is directly in contact with society and has the potential to damage the environment. The protection from the banking sector is greatly needed to conserve the environment. Any form of potential environmental damage can be prevented through a special clause in the credit agreement. In conclusion, banks have a significant contribution to realizing the environmental sustainability of agricultural activities in Indonesia. At present, green banking in credit agreements has not included a clause regarding environmental management. This research suggests the banks to include a clause on environmental protection in credit agreements in accordance with the concept of green banking.

Abstract
The appropriate concept of land use planning is required since the lands have the opportunity to be developed for agricultural purposes. Gunung Mas regency with total areas of 1,084,012 hectares is mainly covered by forest with various slope classes. The objective of study was to allocate the lands to be utilized based on its capabilities and suitability for food and plantation crops. Land evaluation approach was implemented to provide appropriate land use planning especially for food crop farming and plantation. Hierarchically, procedure of land capability evaluation (LCE) was used to classify lands based on their capability to produce common cultivated crops without deteriorating over a long period of time. Therefore, the proper land use for cultivation was further analysis using land suitability evaluation (LSE) procedure to determine fitness of a given type of land for a specific crop. The application of GIS and remote sensing technology were then used to generate additional spatial data as basic planning analysis. The results showed that agricultural system was located and implemented appropriately at arable lands. The use of LCE and LSE procedure can then be implemented to promote proper land use on sustained basis as important part of agroecological management.

Published: June 2021

Abstract
The black tea powder extract produced through the spray drying technique is an alternative to tea steeping or brewing in the industry. The production of black tea powder extract using the 2-stage spray dry method still has problems such as different colour, product swelling or inflate and blocking. To determine the source of the problem, this study used varied outlet temperatures 105°C, 110°C, 115°C, 120°C and total soluble solids (TSS) 31.3, 35.2, 37.2, 43.9, 44.1, 47.4. Spraying through 2-stage spray dryer with combi fluid bed and high nozzle pressure atomizer model SC 40 SDX III by Delavan. The results show a significant difference between the outlet chamber temperatures with the flowrates, the pressures, and the densities. An increase in outlet temperatures by a multiple of 10°C can significantly reduce the pressure and the flow rate, while the temperatures multiple of 20°C can significantly reduce the densities, but not for the moisture contents and the powder colours. Changes in the outlet temperatures did not have a 0.2% effect on the steeping colours but were affected by TSS. The higher TSS’s value gives an increase in flow rate, pressure, moisture content and steeped powder colours of 0.2%

Abstract

Dipterocarpus or keruing belongs to member Dipterocarpaceae, known as commercial timber producer and oil for pharmacological purposes. Of 70 keruing species in the world, 38 species were found in Indonesia and listed in the IUCN Red List. Due to illegal logging, land conversion, low natural reproduction, and specific habitat requirements, the keruing population tend to decrease every year. Conservation effort was urgent for this species, one of which is an increasing number of species through conservation strategies using the conservation nursery concept. Nursery management in this research was conducted through keruing material field collection followed by sowing and acclimatization for seed and wildings, vegetative propagation using the Komatsu-FORDA Fog Cooling System cutting system, and nursing (watering, weeding, fertilizing, and soil change). The result of our research showed that using KOFFCO nursery application, 1226 individuals of fifteen dipterocarpus species seedlings originated from five provinces in Indonesia was conserved. All species are categorized as threatened based the IUCN red-list category and criteria. Hence, more than 60% of these threatened species were conserved and well-managed through the KoFCo nursery. Seedlings collection and KOFFCO nursery, therefore, play a vital role and support in ex-situ conservation effort and management of dipterocarps genetic resources.
