Published: July 2021

Abstract
‘Pedetan’ is a traditional food made from lemuru in Bali. The existence of climate change causes changes in the quantity of fish in the waters of the Bali strait. However, the quality of the ‘pedetan’ must be improved.. This study aims to determine the antimicrobial activity of garlic and Kaempferia galanga in inhibiting the growth of Aspergillus sp. which can contaminate the sardine fish Pedetan. The study was conducted by experimental method by isolating Aspergillus sp. from Pedetan and testing the inhibitory power of garlic and Kaempferia galanga and the Minimum Inhibitory Concentration (MIC) of Aspergillus sp. The results showed that the extract of garlic and Kaempferia galanga can inhibit the growth of Aspergillus sp. Garlic extract can inhibit A. flavus with inhibition zone diameter of 20.65 mm and Kaempferia galanga extract can inhibit the inhibition zone diameter of 23.75 mm. Minimum Inhibitory Concentration (MIC) for garlic extract was 0.4% with inhibition zone diameter of 1.0 mm and Kaempferia galanga with inhibition zone diameter of 1.2 mm. Garlic extract and Kaempferia galanga at 0.5% concentration can inhibit 100% of the conidia Aspergillus sp. Garlic extract and Kaempferia galanga can inhibit the growth of Aspergillus sp. because they contains bioactive compounds that are antimicrobial.

Abstract
Climate change such as an increase in temperature, a change in rainfall patterns, an increase in extreme weather events, and an increase in sea level will affect the agricultural sector, including land degradation. Land degradation can take the form of a decrease in soil fertility, so the use of suboptimal land needs to be applied technology that can increase nutrient availability, and at the same time mitigate the impacts of climate change. The research objective was to obtain technology that could increase soil fertility through the substitution of inorganic fertilizers with organic fertilizer from poultry combined with rice husk biochar in wet suboptimal land. The research was conducted in Sungai Rengas Village, Sungai Kakap District, Kubu Raya Regency, West Kalimantan Province, Indonesia. The method used in this study was an experimental method in the form of a completely randomized design (CRD). The treatment in this study was the application of 5 tons of poultry manure per hectare with 5 tons of rice husk biochar per hectare, so that 7 treatment combinations were obtained, namely treatment A, B, C, D, E, F, and G. The results showed that the combination of 5 tonnes/ha of quail manure with 5 tonnes/ha of rice husk biochar had a significant effect on increasing soil fertility and growth of corn plants and can reduce the use of inorganic fertilizers by 25% to 75% of the recommended dosage.

Abstract
As part of the Jeneberang watershed area, Gowa Regency has an increasing trend of risk of flood disaster which are impact of climate change that has occurred globally. The high rate of population growth and the development of community economic activities are accompanied by the increasing need for space both for settlements and economic activities which results in changes in land cover land use (LULC). This study aims to conduct a study of changes in LULC that can increase the risk of flooding in Gowa regency with watershed area approaches. This study uses a descriptive analysis method with spatial analysis techniques and complemented by other data from agencies, community interviews, and location surveys. LULC data were used in this study are the conversion results from aerial photographs of the Landsat 7 ETM + in 1999 and Landsat-8 OLI / TIRS in 2020 with a map scale of 1: 50,000. The result shows that during the period of study (1999-2020), there were significant changes in LULC in the Jeneberang watershed, where the Jeneberang watershed experienced deforestation of 36.67 Ha, forest degradation of 770.14 Ha and increasing of settlement areas of 3,49747 Ha. The interviews and surveys indicated that the flood disaster-prone areas have grown with residential areas which reduced the water catchment areas and narrowed river boundaries thus increase the potential of flood disaster risk in the future.

Abstract
Increasing temperatures due to climate change caused irregular rainfall in some regions. Changes in rainfall initiate drought to increase every year and negatively impact vital human activities, including agricultural sectors. Drought stress is becoming increasingly important in agriculture because it affects changes in physiological function and leads to a severe decline in crop production. Nano Zn is one of the solutions for drought stress which has a role in enzyme activation, protein synthesis, and carbohydrate metabolism. This study aims to determine the effect of applying nano Zn on rice growth performance in drought stress conditions. The method used was a non-factorial Completely Randomized Design with analysis of variance followed by DMRT at 5% level. The levels of Zn concentration were 0; 0.5; 1; 1.5; 2 ppm Zn. Two varieties were used, ‘IR 64’ as a hybrid cultivar and ‘Mentik Wangi’ as a local cultivar in Indonesia. The variables observed were plant height (cm), number of tillers, number of leaves, biomass weight (g), and root dry weight (g). The result showed that applying nano Zn can increase rice growth due to drought stress on the various variables. The higher the nano Zn dosage, the higher plant height, number of tillers, number of leaves, biomass, and root dry weight by 3-6 %, 2-33 %, 6-23 %, 8-28 %, and 3-34 % respectively compared without Zn. These results can be considered a solution for environmental conditions affected by drought stress by paying attention to Zn concentration level.

Abstract
Particulate matters with sizes below 10 (PM10) and 2.5 (PM2.5) micrometers under polluted air have been causing not only climate change directly/indirectly but also public health problems. These were depended on the level concentrations of PM, chemical species, duration of exposure, as well as meteorological conditions, and how close we are to the emission sources. The aim of the preliminary study is to observe how air pollution concentrations can affect human health. We selected Bandung Metropolitan as a pilot project and located several instruments at Telkom University in the period of 2018-2019. PM2.5 and PM10 data were produced and calculated from microsensors. Health data and related patients from the hospital within 6 km were added to AirQ+ for short and long-term exposure analysis. Results show that temporal data of PM2.5 and PM10 were identified as <20 µg/m3 (in a wet season) to >100 µg/m3 (dry season). In long-term exposure to polluted air, PM2.5 contributed to mortality caused by Chronic Obstructive Pulmonary Disease (COPD) and ischemic heart disease. Meanwhile, post-neo-natal were observed under PM10 mass concentrations. In a short-term period of measurement, March to April and July to August, the respiratory disease has dominant across seasons. Therefore, the coupling of changes in climate and air pollution level will be negatively contributed to more effect on human health.

Abstract
Cashew plants are generally evergreen, so they cover land throughout the year, have a dome-like canopy shape and thick leaves are thought to reduce CO2 emissions, one of the gas that triggered global warming that likely turn into climate change. The research aims to measure carbon stocks and reduce CO2 gas emissions in cashew nuts has been carried out in Pondok Village, Wonogiri, Central Java, one of the cashews growing centers in Indonesia. The method of determining plant samples was carried out on cashew crops by monoculture, the age groups (KU) were differentiated 1, 2, 3, 4 and 5, the measuring plots were determined purposively due to the limited population in the same age plot. Carbon stocks were analyzed using the allomeric method, while CO2 emissions were calculated descriptively. The results showed that cashew plants have the ability to increase carbon stocks and reduce CO2 gas emissions, this ability is kuadratic in line with plant KU. The highest carbon stock by KU 4 plants, the highest ability to reduce CO2 emissions is found in plants aged 30-40 years. The implications of research results on crop management related to emission reduction and increase in C-stock are discussed.

Abstract
Climate change is causing garlic cultivation problems almost all over the world. One of the efforts that can be made to obtain high yields is the use of quality planting materials. Planting material from bulbil and tuber second generation (G2) from bulbil is feasible to study for use as planting material. This study aims to examine the yield potential of various kinds of garlic planting material. The study used a randomized complete block design with 2 treatment factors. Factor 1 were the type of bulbs (parent bulb, parent bulbil, bulb G2, and bulbil G2), and factor 2 were the immersion concentration of GA3 (0 ppm, 50 ppm, 100 ppm, 150 ppm) and repeated 3 times. The results showed that conditions of high extreme temperatures caused abnormal growth of garlic, low plant vigor, decreased growth and yield and high plant mortality. Although the plant growth is not normal, the planting material for bulbs G2 and bulbil G2 has the potential to be developed as planting material. This can be seen from the variables of plant fresh weight, plant dry weight, bulbs dry weight and bulbs diameter.

AbstractSea level variation is an important key for hazard mitigation in the coastal region to study climate change. In the last decade, reflected GNSS signals have been used in many applications, such as snow, sea level, and ocean storm monitoring. In this research, we use GNSS-Reflectometry co-located with a tide gauge station to monitor sea-level variations. We use the Signal Noise to Ratio (SNR) data to derive sea-level height from GNSS. One-month comparison of sea-level variations has been made from a tide gauge and a GNSS measurement in Barus, North Sumatra Indonesia. The results have a mean bias of about 2 cm with a root mean square error of 11 cm and a correlation coefficient value of 0.90. Our result demonstrates that the GNSS-Reflectometry technique is potential to provide a new approach to monitor sea-level changes that complement the existing tide-gauge networks in Indonesia.

Abstract
Plant production and changes in physiological aspects during the growing season can be influenced by climate change, one of which is the light factor in Indigofera tictoria. The production of secondary metabolites Indigofera tinctoria as a source of natural dyes is responsive to light. This study examines the effect of shading time intervals and light intensity on the growth of Indigofera tinctoria L. The study used a Randomized Complete Block Design with a split-plot design consisting of 2 treatment factors, namely: the shading time interval as the main plot with five levels, namely 1-4, 1-8, 1-12, 8-12 and 4-12 weeks after planting. Light intensity as a subplot with three levels, namely the light intensity of 50%, 25%, and 10%. The results showed that combination shading time interval and light intensity significantly affected the number of nodia, leaf area of 8 WAP root biomass. Shade time of 1-4 weeks with a light intensity of 50% showed the highest number of nodia was 45.67 nodia, root fresh weight was 137.00 g, and root biomass was 60.10 g. The shading time interval had a significant effect on the net assimilation rate of the vegetative phase and root fresh weight. The vegetative phase’s net assimilation rate in the 8-12 WAP shading time treatment was 0.029 g.cm2.day−1. The longer the shading time interval with the lower the light intensity can increase the area index and decrease plant growth.

Published: July 2021

Abstract
Gunungkidul District has an area of 485.36 km2, which is a karst area that is included in the Gunung Sewu geopark. The uniqueness of mount karst is mainly in the abundance of carbon stocks in the karst. The karst area’s location has underground river flows, shallow soil solum, and high levels of drought. The objectives were to create actionable strategies for climate change mitigation to reduce the risk of damage to karst areas. The mitigation action strategy aims to reduce the carbon emissions rate from various sources and increase the Karts area’s absorption rate, a community forest area. The methodology uses qualitative research comparing baseline carbon data based on the allometric model. Data collection carried out using the FGD (Focus Group Discussion) method. The results showed that community forests’ average carbon stock was still below the lowest standard of carbon stock’s feasibility in the woods. This situation does not guarantee optimal carbon storage sustainability due to the phenomenon of land-use change and need-cutting. Therefore, the mitigation action strategy needed is to encourage local policies at both the village and district levels in climate change mitigation efforts. This policy will form the basis for mainstreaming climate change mitigation as part of the government’s widely supported work.

Abstract
Research on human activities and socioeconomic development analysis on the Marine Ecological Carrying Capacity (MECC) evaluation index to climate change adaptation at the Sentra Kelautan dan Perikanan Terpadu (SKPT) Nunukan Regency, North Kalimantan in 2015-2019 has been carried out. The purpose of this study was to determine changes in human activity and socioeconomic development of MECC as an evaluation of adaptation and mitigation to climate change. The method using in this research is an approach to the concept of Integrated Ocean Management (IOM) in the form of MECC. MECC can be used as a tool to see the effectiveness and efficiency of a policy on the environment. MECC consists of two components, namely carrying object (OI) and carrier resilience (RI). Carrying object analysis was performed to determine changes in the value of the human activity index and socio-economic development. The value of the carrying index which consists of human activities (HI) and socio-economic development (SI) activities in Nunukan Regency shows a decline during 2015-2019. The value of HI decreased by 82% from 0.19 in 2015 to 0.03 in 2019 due to increased activity in the fisheries and marine transportation sectors. Meanwhile, the SI value in 2014 was 0.25, down 57% to 0.11 in 2019. This was due to the increase in socio-economic activities in Nunukan Regency. Adaptive capacity can be the main key in preventing a decrease in the carrying index. The form of adaptive capacity carried out by utilizing information, building partnerships among the private and non-private sectors, strengthening stakeholder involvement and control, growing capacity constructing, enforcing regulatory frameworks, and protecting weather change and different environmental adjustments in adaptive management structures.

Abstract
Drought is one of the climate change phenomena that has a profound impact on agricultural crops. Various adaptation strategies are used to deal with the impacts of climate change, one of which is the ratoon system of rice cultivation. This study aims to examine the effects of providing a combination of organic amendment and the application of PGPR on soil characteristics, growth, and yield of salibu ratoon system in the rainfed dry land. The research was conducted in Wonosari Village, Gondangrejo, Karanganyar, Central Java. This research used a complete randomized block design with three replications consisting of 2 factors. The first factor is the organic amendment, which is without the addition of organic matter (C1), compost (C2), and rice husk charcoal (C3). The second factor is the PGPR treatment, which is non-inoculated PGPR (P1) and inoculated PGPR (P2). Data analysis used ANOVA level of 5% followed by Duncan’s test. The results showed that the addition of organic matter and the inoculation of PGPR affected the variable root length, yield, and biomass. The addition of organic matter and PGPR can increase crop yields and plant resistance to drought stress by maintaining soil moisture and root elongation mechanisms. Based on the research results, the addition of rice husk charcoal and PGPR inoculation is the best combination for ratoon rice cultivation in the rainfed dry land.
