Abstract
The utilization of Split AC as a water heater is now initiated but still uses a heater from electricity. Besides that, the use of solar thermal radiation as a source of heating has already made much. In this study discussed if both systems were merged into a hybrid-Solar Thermal Air Conditioner (STAC) system. The STAC system will combine the heat refrigerant on a discharge line compressor with a solar heat collector. This system has been designed in previous studies only limited to the analysis of the achievement of the temperature is 40 °C within 20 minutes. But the obstacles experienced by heat cannot last long because it utilizes peak load time from solar radiation and thin tank insulation. For it developed a hybrid system with the replacement of a hot water tank. The method begins by creating a model for the hybrid system modification, the determination of tank insulation material and heat storage wall thickness so that the water heat loss can be reduced. Then on the solar collector modified by the pipe installation series as well as the 20° collector tilt angle. For circulation flow refrigerant from the discharge line compressor added automatic control, it is expected the performance of the system more maximized. The results can be seen that the water heating time can reach values above 40 oC in 30 minutes, the hybrid system efficiency is 47.9%, and the refrigeration efficiency is 75%.

Abstract
Many studies have reviewed economic benefits and ecological benefits of the integration of crop-livestock, but the author has not found a study that examines the farmer’s welfare. This is important because welfare is one of the sustainable (agricultural) development goals. In addition, as an agrarian country, attention to the welfare of farmers in Indonesia is considered very strategic. This study aims to examine the value of the Farmer Household Income Exchanges Rate (FHIER) as an indicator of the welfare level Integrated Plantation of Polyculture Farmers’ (IPPF) households. This study was conducted in Tasikmalaya Regency. The survey method has been carried out to 83 respondents (IPPF). The result based on the value of FHIER shows that IPPF households included in the welfare category. Meanwhile, the result of statistic analysis shows that revenue is a more important factor in determining FHIER. In more detail, it is known that revenue and expenditure from integrated plantation polyculture activities are becoming more important factors as determining the value of FHIER. Therefore, it is suggested to improve the revenues of farming households through the integrated plantation of polyculture farming in order to reach the welfare category (higher value of FHIER).

Published: June 2020

Abstract
The use of shallot bulbs as the main planting material has many weaknesses, so one of the solutions is to use botanical seeds (True Shallot Seed). Physiologically, good seeds have embryos, endosperm, radicles, and testa. Seed viability demonstrated by the viability of seeds, metabolically active, and has enzymes that can catalyze metabolic reactions for germination. The purpose of this study was to determine the potential of the seed to determine its quality. One method for testing seed potential is the viability test through the tetrazolium test and the vigor test through Germination Rate. This research used local varieties of Trisula yields in 2015 (TR 1), Trisula yields of 2018 (TR 2) and as a control used Tuk-Tuk varieties. The results of the viability test using tetrazolium showed that the average viable seeds in the TR1 variety were 90.5%, TR2 94%, Tuk-tuk 95.5% which meant that the potential of the seed was still good because it was over 80%. The results of the vigor test through the measurement of germination rate gave significantly different results on each variable with an average yield of TR1 8.45% per etmal, TR2 11.41% per et mal, and Tuk-tuk 14.27% per et mal.

Published: June 2020

Abstract
Microgreens are young vegetable greens that harvested when the cotyledons have fully developed, which usually occurs at the age of 7-14 days after germination. Kenikir is a medicinal vegetable plant that has many health benefits. Microgreens cultivation in Indonesia is increasing along with public awareness of health, but the information about the best planting media for the cultivation of microgreens is still very limited. This research aimed to study the effect of a combination of manure and biochar on the growth and N uptake of kenikir microgreens. The research conducted in Mojogedang, Karanganyar, Central Java using a factorial complete randomized block design (RCBD). The first factor is the type of manure consisting of control, cows, and goats. The second factor is the type of biochar consisting of husks, coconut shells, and rice straw. The results showed that the combination of manure and biochar treatment can increase plant N uptake. The combination of cow manure with various types of biochar produces the highest N uptake. Cow manure combined with husk, coconut shell and straw biochar successively produced N absorption 1.72%, 1.81% and 1.91%. However, the large uptake of N does not influence the growth of microgreens.. The variety of manure did not significantly affect the growth (plant height, leaf area, and root length) of kenikir microgreens. Biochar type affects plant height. Husk biochar increases plant height by 16.29%, and coconut shell biochar increases plant height by 9.03% compared to straw biochar.

Abstract
Indonesia is facing magnificent dilemma for providing food and other agricultural product to meet the food requirement of rapidly growing population and preserving land resources, health of soil ecosystem and mitigating and adapting to climate change (CC). About 70% of agricultural soils in Indonesia has been exhausted and over mined and categorized as sick soils. The impacts of CC has already hit Indonesia and caused the rise of temperature about 0.2-0.3 °C per decade and sea level (SRL) about 5 mm per year, drought and floods occur more frequently, the change of rainfall intensity and rainfall pattern, the shifting of planting season and lead to the decreasing of crops yield or yield loss significantly. The CC along coastline (95,181 km) increases and cause a severely more consequence on the livelihoods inhabitants (40% of total population) and decreasing of lowland agriculture. The paddy fields in coastal area until 2050 will decrease around 174,461 ha in Java, 8,095 ha in Bali, 78,701 ha in Sulawesi, 25,372 ha in Kalimantan, 3,170 ha in Sumatera and 2,123 ha in Lombok Island. The effort to restore and maintain the health of soil ecosystem, enhance the productivity and to mitigate and adapt to the climate change can be done by adopting climate smart sustainable agricultural (CSSA). The main objectives of CSSA are to increase the productivity and income (economically viable), improve and maintain the health soils ecosystem, build and strengthen the resilience to climate change and mitigate to reduce the GHGs. The integrated of CSSA in a climate smart sustainable farming village (CSSFV) is expected to more effective for building the resilient the soils ecosystem and farmers, mitigating and reduce the GHGS, increasing the productivity and income of the farmer and enhancing the food security in sustainable ways.
