Published: April 2021

AbstractAgriculture could be a solution for climate change by the widespread adoption of mitigation and adaptation actions. This happens with the help of best management practices such as organic fertilizer. The types of organic fertilizer will affect beans’ production and their quality characteristics, both physically and their nutrient content. The purpose of this study was to determine the effect of brown algae extracts as organic fertilizer applied to bush beans’ quality. The study was conducted in October 2017, on IVEGRI’s experimental field, Lembang, Indonesia about 1200 m above sea level. The experiment used 10 treatments and 3 replications), which were a variation dose of NPK and Liquid Organic Fertilizer (LOF). The physical and chemical characteristics of testing consisted of length, diameter, texture, water content, TSS, fibre, and vitamin C. The quantitative and qualitative analyses were used to determine the beans’ shelf life. Freshness test parameters were consisting of colour, texture, and appearance. Panelists provided a score of 1 (strongly like) to 5 (strongly dislike). Data were statistically analysed, followed by Tukey’s test (5%). The results showed that LOF with standard NPK dosage can increase vitamin C and fiber content of bush beans. Higher LOF dose usage can reduce the change rate of bush beans’ quality on shelf life. LOF from brown algae can reduce the chemical fertilizers used in the soil, so it will slowly create environmentally friendly vegetable production.

Abstract
The use of agro-industrial wastewater can reduce environmental pollution and emissions of greenhouse gases into the atmosphere. One of them is by utilizing its acidity to dissolve phosphate rock (PR) which is used for P fertilizer. The purpose of this study was to determine the effect of agro-industrial wastewater and PR dosage for P availability and nutrient uptake by corn in ultisol soil. Split plot design was arranged with wastewater of tapioca and tofu as a main factor and dosage of PR after acidulation as a sub-plot. The results showed that wastewater had no effect on the available soil P, soil pH, N uptake, P uptake, and dry weights of corn plants, but PR dosage had a significant effect on available soil P, N uptake. There is an interaction between agro-industrial wastewater and PR dosage on the P availability. For acidulation with tofu wastewater, the PR dosage used is lower for the same soil P availability compared to tapioca wastewater. At high P dosages, acidulation PR with wastewater does not have a significant effect on soil P availability. Phosphorus and nitrogen uptake by corn increased with the application of 950 kg ha-1 acidulated PR.

Abstract
The criticality of watersheds in Indonesia can trigger water scarcity and trigger environmental damage if it is not handled as early as possible especially during uncertain climate change conditions. The long-term impact of this condition, if it is not handled properly, is the damage to the ecosystem and habitat that can disrupt rainfall patterns. Regulatory issues, sub-optimal community empowerment, lack of public awareness, and the decrease of forest productivity are some of the causes. This study was aimed to find out the extent of environmental deterioration using indicators of Erosion Hazard (EH) and landslides and to formulate environmental management strategies as an effort to conserve the environment. Data collection for the first purpose was undertaken by observation, literature review, documentation, and for the second purpose was conducted by measurement, observation, and interview. The results of the analysis can be concluded that the level of environmental damage in the Widoro Sub-watershed was in the category of minor damage. It can be seen from EH and landslides that occurred in the Widoro Sub-watershed. The erosion and landslides that occurred were at a harmless level. The environmental management strategy included counseling and assistance activities, improvement of sanitation facilities, and monitoring and law enforcement on community activities related to land use, erosion, landslide and disaster, and also the selection of plants with high value economic.

Abstract
A hydrogen reactor (HR) as co-combustion in a motor engine for reducing emission gas (EG) production has been successfully developed. The use of a motor engine in transportation does not only consume a lot of gasoline but also creates depletion in fossil fuel resources which subsequently increases the EG production. The increase of EG caused the highly hazardous to the environment such as global warming that affected climate change. To overcome this problem, we investigated the effect of HR on reducing EG production and consumption of gasoline for the motor engine. We manufactured the volume 34.5mL, 40.8mL, and 56.5mL of HR, then we used Halanaerobium hydrogeninformans water as hydrogen sources. For combustion, 1L Pertalite gasoline was applied in the engine motor. The experiment was conducted in variation temperature of HR (100 °C, 110 °C, 120 °C, 130 °C, 140 °C), and velocity of the motor engine (2000rpm, 3000rpm, 4000rpm). We examined that the EG production namely hydrocarbon, carbon dioxide, and carbon monoxide were decreasing with the use of HR compared without the HR for all experimental conditions. The result tests also show that the use of HR reduced the consumption of gasoline along with the combustion process. This study demonstrated that HR as co-combustion combined with Halanaerobium hydrogeninformans water has the potential for environmental protection such as climate change due to global EG production.

Published: April 2021

Abstract
Construction activities gradually consume energy during their life cycle, namely material extrusion, transportation, production, assembly line, installation, demolition and disposal. This research aimed to identify research about energy such as embodied and operational energy. Operational energy is energy that is used during building life cycle to decrease global warming effect. This research used a qualitative method to identify and review some literature related to decreased energy construction. This study showed that 98% of researchers focus on energy efficiency in the design, construction and operational stages. Only 2% were investigating at the initiation stage. Some recommendations can be drawn suggesting that energy reduction is possible by applying optimization strategy to all project life cycle (PLC). Initiation and design phase are indirect energy optimization phase through policies and design buildings, which significantly impact energy decrease for further phases. In contrast, construction and operations phase is direct energy optimization phase through energy efficiency on each activity.

Abstract
The development of oil palm plantations on peatlands leads to the release of greenhouse gases (GHG) into the atmosphere. Soil amelioration can improve the fertility of peat soil because consists of polyvalent cations that overcome the negative effect of high-level organic acid as well as reduce GHG emissions. This study aimed to observe the effectiveness of soil amelioration for reducing carbon dioxide (CO2) emission from oil palm plantations on peat soil. The study was carried out on smallholder oil palm at Kumpeh, Muara Jambi District, Jambi Province. The study was arranged with six treatments and four replications of a Randomized Completely Block Design (RCBD). The treatments were control, manure, compost of empty fruit bunch, lateritic soil, pugam (peat fertilizer) type A and type T. The results showed that ameliorants could reduce CO2 emission by approximately 1.7 – 34.4% compare to control except program T. The lowest CO2 emission was produced during 5-7 weeks after the first application of ameliorants. The soil ameliorants should be added every 4 months to control the CO2 emissions from peat soil. Long term observation is needed to more explore the potential of ameliorants to reduce CO2 emission from oil palm plantation in peat soil.

Abstract
The change in morphological patterns upstream of Ogan River were investigated to analyze land-use and climate change impact on the river meandering. This study aimed to investigate morphological changes of Ogan River in Lengkiti area between 1996 and 2019. Two sets of Landsat areal (1990 and 2016) were used to identify the morphological changes during flood periods. Data analysis used the maximum likelihood approach, t-test and Spearman correlation analysis. The morphometric indicators such as river width (W), meander neck length (L), axis length (A), curvature radius (R), water flow and sinuosity of meander (C) were extracted to identify the morphological pattern of river meandering. Analysis of land-use change used Support Vector Machine (SVM) and kernel function method to interpret the meander parameter change. Ogan River in Lengkiti, such as Batu Kuning and Marga Jaya segments, which have rice field and settlement cover from 1996 to 2019, had been cut off. Cut-off occurred due to landslides that entered river’s body and narrowed riverbed. This fasted river flow even though river discharge was same, caused intensive erosion and sedimentation. The increase in water velocity increased flow power, shortened flow distance and cut-off caused reduced meander’s sinuosity (C).

Abstract
Climate change poses weather pattern and heat stress on the soil, along with the sea-level rise and groundwater depletion lead to the expansion of soil salinity hazard on arable lands and turn it to saline-prone lands. In Indonesia, soybean profitability and competitiveness over rice and maize are relatively lower leads to the lesser priority in the development. Further, the cultivation area is declined and start utilizing suboptimal lands, including saline-prone lands. Salinity affects soybean productivity; therefore, the use of salinity-tolerant varieties is key to successful soybean cultivation in saline soils. The study was carried out to evaluate the tolerance of soybean varieties under salinity stress. The experiment was conducted at saline field in Lamongan during 2017 dry season. Forty-one soybean varieties were evaluated based on their responses under salinity stress. Research observations included soil electrical conductivity as the salinity measure, plant growth parameters, yield components, and yield. The data were analysed using descriptive statistics and the tolerance to salinity stress was assessed based on Stress Tolerance Index (STI). Evaluated soybean varieties performed various responses to different salinity levels, both in terms of growth and yield parameters. In general, lesser results were observed for most parameters at higher salinity level. Based on the value of STI, 7 varieties were tolerant to salinity but only 2 among them showed yield productivity of >1.5 t ha-1, i.e., Dena 1 and Lokon. Both varieties are very potential to be used as high-yielding parents for salinity tolerant soybean breeding programs.

Abstract
Plants change their vegetative and reproductive activities as a mechanism to adapt to climate change. This study aimed to document the flushing, flowering and fruiting patterns of 16 Rutaceae species grown at Purwodadi Botanic Garden, East Java. Observations were conducted fortnightly for four years, covering abundances of leaves, flowers and fruits, and used a scoring method from 0–4. The results showed two species with differences in their vegetative activities. Murraya koenigii (L.) Spreng. and Zanthoxylum rethsa DC shed their leaves to a class of 2 (50%). The observed flowering and fruiting patterns included frequency (continual, sub-annual, annual and supra-annual) and class (regular and irregular). The observed species fell into four different frequencies of flowering patterns: annual (nine species), sub-annual (two species), continual (four species) and supra-annual patterns (one species). Most of the observed species performed flowering patterns that differ from their fruiting patterns. Seven species showed same flowering and fruiting patterns, namely Clausena lansium (Lour.) Skeels, Euodia suaveolens var. ridleyi, Glycosmis pentaphylla (Retz.) DC., Luvunga sarmentosa Kurz., Micromelun minutum Wight & Arn., Murraya paniculata (L.) Jack and Triphasia trifolia (Burm.f.) P.Wilson. Some species belonging to regular class performed same flowering time during observation, such as Euodia suaveolens var. ridleyi, Citrus lucida (Scheff.) Mabb., Glycosmis pentaphylla (Retz.) DC, Lunasia amara Blanco, Melicope latifolia (DC.) T.G. Hartley, Murraya paniculata (L.) Jack., Triphasia trifolia (Burm.f.) P.Wilson, and Zanthoxylum rhetsa DC.

Abstract
Indonesian government has launched the Low Carbon Development (LCD) policy which is expected to internalize into the upcoming National Medium-term Development Plan (RPJMN) 2020–2024. LCD aims to support economic growth through low emissions development activities while minimizing the exploitation of natural resources. Hence, the study’s goal was to decide the extent of implementing climate change programs at the local level, as a preliminary study to find the region’s readiness towards LCD. This research was conducted at Pekalongan, which was categorized as a highly vulnerable region to climate change in Central Java. Data was collected using a literature study, focus group discussions (FGD), and in-depth interviews. The results suggested that The Pekalongan City planning document had several adaptations and mitigation plans in response to climate change, supported by several regulations. The energy, waste, and agriculture sectors were the highest contributors to carbon emissions. This study also outlined the implementation of programs and strategies in the energy and waste sectors to reduce greenhouse gases and the obstacles they face, excluding the agriculture sector, because of limited data availability. In general, the response of Pekalongan city to climate change was still hampered by coordination between sectors, not all were elements involved. Furthermore, greenhouse gas inventory had not been specifically budgeted.

Published: April 2021

Abstract
The novel coronavirus COVID-19 outbreak was first reported in Indonesia on March 2, 2020 and then it called for prevention. At the same time, emissions of carbon dioxide reported to have decreased that imply global climate change. Furthermore, the climate change due to a reduction in CO2 emissions during the COVID-19 pandemic affected the demand and supply side of goods and services which in turn had an impact on the economy. One of important indicators in macroeconomics is the inflation rate. Therefore, this study aims to examine the impact of climate change due to the reduction of CO2 emissions during the COVID-19 pandemic and Coronavirus disease on inflation and food inflation in Indonesia. This study uses time series daily data and analysis using Ordinary Least Squares (OLS). The result show that the number of COVID-19 cases has a negative effect on both inflation and food inflation, while the number of recovered cases has a positive effect on both dependent variables. The number of death is only significant to the inflation rate, but it is not significant to the food inflation. The variable of temperature as a proxy variable of climate change has negative influence to the food inflation, but it has not any effects to the inflation rate. In addition, the level of citizen compliance with physical distancing will determine the level of CO2 emission reduction.

Abstract
Kelambut is an important instrument for the Waena Tribe and plays a vital role in raising awareness about climate change mitigation. However, until now there has been no in-depth study about Kelambut music. The purpose of this study is to identify the traditional music of Kelambut musically and to know the meaning of Kelambut for the Waena tribe. This research was conducted using qualitative methods. The data source is the music of Kelambut itself; the informants are the chief of the Waena tribe, performers, and local cultural observer. All data collected through participative observation, interviews, records, and FGDs were analyzed using ethnic music theory and structural-functional theory. The results are: (1) Kelambut is a traditional musical instrument made from natural environmental wood in the Sentani area. It resembles a boat and is played by hitting the inside part and functions as a communication tool and musical accompaniment to dance. (2) Besides valuing it as a work of art, to balance life with the environment, the Waena tribe also interprets Kelambut as sacred music which provides protection, as a liaison with their ancestors, as a sign of the appointment of a tribal chief (Ondoafi), and as the cultural identity.
The Determination of Tidal Constituents using Wavelet Base Harmonic at The Strait of Malacca
Authors: Abubakar A G , Mahmud M R , Tang K K W , Husaaini A 
Published: April 2021

Abstract
Activity at the coastal areas required accurate tidal analysis and prediction. Tides are a result of the response of the water body to the attracting forces exerted by the moon and sun. In this paper, a new novel wavelet base harmonic model (WBH) for tidal analysis and prediction is presented. Discrete wavelet transformation is being employed to present the relationship between multiresolution analysis and wavelet to show the harmonic amplitude and phase angle as a sum of shifting and scaling functions. The coefficients of the shifting and dilating function are resolved to obtain the harmonic constituent (amplitude and phase angle) of a seawater level. It is found that the predicted tide result obtained at four tide gauge stations using the wavelet-based harmonic model agreed with the observed water tide. To test the efficiency of the model root mean square error the correlation coefficient was used.
