Authors: Tunas I G , Azikin H , Oka G M
Published: November 2021

Extreme rainfall is the main factor triggering flooding in various regions of the world including Indonesia. The increase in intensity and duration of current extreme rainfall is predicted as a result of global climate change. This paper aims to analyze the impact of extreme rainfall to the peak discharge of flood hydrographs at a watershed outlet in Palu, Sulawesi, Indonesia. Maximum daily rainfall data for the period 1990-1999 recorded at the Palu Meteorological Station, Central Sulawesi were selected using the Annual Maximum Series Method, and grouped into two types. Type I is the maximum daily rainfall data with extreme events and Type II is the maximum daily rainfall data without extreme events. Frequency analysis was applied to the two data groups using the best distribution method of: Normal, Normal Log, Pearson III Log, and Gumbel to obtain the design rainfall of each data group. In the next stage, the design rainfall transformation into a flood hydrograph is performed using the Nakayasu Synthetic Unit Hydrograph based on a number of return periods in one of the rivers flowing into Palu Bay, namely the Poboya River. The analysis results show that the design rainfall graphs with both extreme rainfall and without extreme rainfall are identical at the low return period and divergent at the high return period with a difference of up to 21.6% at the 1000-year return period. Correspondingly, extreme rainfall has a greater impact at the peak of the flood hydrograph with increasing return periods ranging from -1.28% to 26.81% over the entire return period.

Published: November 2021

The number of workers with disabilities in public and private institutions continues to increase. However, this number has not met the quota target as stipulated in the law on people with disabilities. Therefore, attention from government agencies, the private sector, and other stakeholders is needed. Collaborative governance is often expected to be able to solve complex policy problems and support the creation of sustainable development. This paper aims to explain the stages of collaborative governance in realizing an inclusive workforce for people with disabilities to achieve sustainable development goals in the Special Region of Yogyakarta. This study used a qualitative descriptive design. Data collection was carried out by observation, in-depth interviews, and literature study. The results showed that the collaboration of stakeholders involved in realizing an inclusive workforce was needed. Collaboration has been carried out with the manpower office as the main actor although in its implementation it is still not aimed at achieving the same interests. At the initiation stage, the collaborative process carried out is not yet based on a clear cooperation framework and action plan from each stakeholder. Although there have been deliberation efforts made, they have not succeeded in creating an effective working group and building consensus to achieve inclusive workforce. In addition, the partnership that has been formed has not encouraged stakeholders to jointly evaluate the progress that has been made in cooperation. Thus it can be concluded that collaborative governance in realizing an inclusive workforce for people with disabilities has been implemented but has not yet reached the stage of being able to build a strong framework of cooperation and create broader support for this cooperation.

Authors: Badri Muhammad
Published: November 2021

The spread of COVID-19 is increasingly massive and it involves local transmission. Facing these issues, community-based risk reduction is truly needed. This study aims to describe the society-based risk communication for COVID-19 disaster prevention through “Keep the Village” program, called Jaga Kampung. This study used a qualitative approach by collecting data through interviews with COVID-19 response volunteers in the Jaga Kampung program in Riau Province, Indonesia. This study finds out that the Jaga Kampung program has the aim to prevent the spread of COVID-19, maintain security stability, and protect people's food needs. The implementation of these activities involves the collaboration of communication actors from the police and the army who works in the village, village leader, village health worker, society leader, and volunteer. The officers of Jaga Kampung convey education and socialization of health risks humanistic and persuasively to villagers and newcomers. Communication is done through face-to-face, outdoor media, and social media such as WhatsApp, Facebook, YouTube, and Instagram. This community-based risk communication can increase society's participation in the prevention of COVID-19 so that the health and socio-economy of society is maintained.

Published: November 2021

Due to a rapid increase in urban and built-up areas, the East Coast – Gulf basin of Thailand faces flood hazards more frequently than in the past. In this study, we aim to assess the effects of building construction on flooding, and any link between them. The FloodMap model is used to simulate flooding in the study area in September 2015. Two flooding scenarios were designed; one based only on land surface elevation and the other one with building construction included on the land surface. According to the result, we found that human construction increases flood hazard in the study areas, particularly flood depth. Flood areas are also found to increase if the human factor is added into the model, but in a lesser extent. With human construction, paved road is found to have the highest flood potential compared to other types of road. Built up areas are more flooded, while flooding extent is almost similar to results from the scenario of no human construction in forest and agricultural areas.

The roles of human geography in disaster studies
Authors: Assriyani  , Hastuti
Published: November 2021

A disaster is an event or series of events which threaten and disrupt the human lives. The studies of disaster are constantly considered related to humans because humans act as the causative factor, victim and at the same time the executant of the effort in disaster handling. Pioneered by Gilbert White and pursued by other experts, human geography later shows the roles in examining issues in disaster studies especially in disaster mitigation. Based on several research and notions, many experts in human geography agree that there is nothing natural in natural disaster. Although the disasters are often affected by geosphere physical phenomenon but various human actions and activities on the face of the earth cause certain population to be more prone to natural disaster. If the risks toward disaster need to be reduced, bigger attention needs to be given to minimize population vulnerability, increase people capacity to overcome disaster and strengthen people capability to adapt to disaster area in a long term. Currently, UN as the responsible party in reducing risk of international disaster has been doing community resilience effort adopting Hyogo Framework for Action (HFA) 2005–2015: building the nation and community resilience towards disaster, followed by Sendai Framework for Disaster Risk Reduction (SFDR) 2015-2030: reducing disaster risk and loss.

Published: November 2021

Drones are a very important medium in the world of aerial photography to map military operations, agricultural areas, plantations, mining, urban planning, disaster mitigation, and outreach to remote areas and two types have been identified which are the winged and quadcopter. This research was conducted to map the drought-prone areas during the dry season in the Sermo Reservoir area, Kokap, Kulon Progo Regency between 14-15 August 2019. This involved the use of the DJI Spark quadcopter due to its more stability and wind resistance. The process involved connecting the DJI Spark drone remote controller to a smartphone, opening of DJI Go application, DJI Spark drone activation, smartphone installation on the remote controller holder, propeller installation, GPS settings in a locked position, drone flight and position adjustment, and capturing of the images on the smartphone screen. The results showed the water flow of the Sermo Reservoir has decreased by approximately 4 meters due to the dry season. This was evident in the changes from its original position of136.6 meters above sea level to 132.6 meters and this limits the quantity of water available to irrigate rice fields. The reservoir still has the capability to supply 800 liters per second in Pengasih District but the results of the aerial photographs showed the existence of drought and a decrease in the water discharge.

Published: November 2021

This study aims to determine the achievement of disaster mitigation in handling COVID-19 for the elderly through social welfare services. The elderly are the age group that has the highest risk of death due to the COVID-19 pandemic. This research is descriptive qualitative using in-depth interviews, observation, and documentation. Respondents selected by purposive sampling included government agencies, elderly families, social workers, nursing homes, senior regional commissions, the Yogyakarta Province COVID-19 task force, and the elderly. The study found that disaster mitigation in handling COVID-19 for the elderly was not optimal in lesson learn of understanding and knowledge to the elderly. The result of an emergency response plan has not been responsive because there is no accurate database and systematic and integrative standard procedures in handling the COVID-19. Thus, the assisted early warning system is already running well because of the integrated coordination from the family, local government to the national level in the authority of the COVID-19 Task Force. The mobilization of resources needs has not been able for the particular needs of the elderly during the COVID-19 pandemic in several areas in Yogyakarta Province, especially for neglected elderly. Therefore, the findings of this study recommend optimizing each stage in disaster mitigation to minimizing the risk of death in the elderly effectively.

Published: November 2021

The Covid-19 pandemic poses a threat of forest destruction, especially forest fires, along with the increase of intensity of humans entering and exploring the forest. It is suspected that many people who live in urban areas have lost their jobs due to layoffs and moved to villages, and then opened new lands because their supporting facilities were no longer relevant to the current conditions, the COVID-19 pandemic. These people who abruptly start their activities in the forest and do not understand the rules of preventing forest fires are making the forests vulnerable to fires. The purpose of this study was to determine the effect of the COVID-19 pandemic on the dangers of forest and land fires in South Sulawesi. It used a descriptive method, and data was collected through in-depth interviews with communities that are affected by the COVID-19 pandemic and live around the fire-prone forest areas. The results of the observation were processed by descriptive analysis to get the conclusion. The results showed that about 72% of the affected people are carried out activities in forest areas which 78% of them did not understand the rules of forest and land fire hazards. The results of this study will be recommended to the government, particularly to the policymakers in controlling forest and land fires, especially during the Covid-19 pandemic.

Published: November 2021

Mangrove forests are tropical and subtropical forests that grow typically along the coast or river estuaries. Black mangroves are a type of mangrove found in South Sulawesi, precisely in Maros, Pangkep, and Barru Districts. The decline in black mangrove populations overcomes the threat limit to germplasm which can lead to reduced genetic diversity in black mangrove plants. To reduce the incidence of extinction in black mangroves, information on genetic diversity using one of the markers is required, namely morphological markers in taking samples of tree parts taken, namely the leaves, stems, and roots which are then for monitoring carried out in the Biotechnology Laboratory and tree breeding. The method used in this study is based on the literature on the development of the Tropical Fruit Descriptor information system. The results of the three studies proved that there is a difference between the evidence and the interprovenencies. The very close morphological kinship between them proved to be found in Pangkep. Pangkep’s provenance has a high coefficient compared to the proof of Maros and Barru, which is at the time level of 70%, while the proof of Maros has the lowest coefficient compared to the proof of Barru and Pangkep, which is at the gathering level of 64%.

Lower mountain forest in the complex of Mount Bulusaraung Bantimurung Bulusaraung National Park, is a one of bird’s habitat in the South Sulawesi. This area is a tourist destination, especially mountain climbing activities. Thus, it is necessary to know the diversity of animals, especially birds on this hiking trail, so that the information can be used to support ecotourism activities. This study aims to analyze the diversity of bird species in the complex of Bulusaraung Mountain, Bantimurung Bulusaraung National Park in order to support ecotourism activities. This research was conducted from April to June 2018. Data was collected using the line transect method on three lines, namely the Balleanging, Kattokaddaro and Tompobulu lines. The second and third paths are hiking trails, while the rest are trails leading to community agricultural areas. The geographical position of the transect line was recorded using GPS. The GIS method was used to generate a bird watching trail map. Data analysis was carried out to calculate the individual density and frequency of bird presence. In addition, the species diversity indices, species evenness indices, and species richness indices were also calculated. The results showed that there were 44 species of birds found in the study area, which were 16 species in the Balleanging line, 27 species in the Kattokaddaro line and 37 species in the Tompobulu line. The highest bird species diversity indices value was found on the Tompobulu line (H' = 2.93), while on the Kattokaddaro line it was H' = 2.73 and the Balleanging H' = 2.55. The results of this study will support the management strategy in Bantimurung Bulusaraung National Park in order to harmonize the conservation of biological resources through ecotourism activities that involve local communities to increase their economic income.

Population growth creates competition in meeting the needs of daily life. The forest area is the target for the community to depend on for their life. Palm trees are forest products that have many benefits. This study intends to describe the process of tapping palm sugar, calculate production costs and business income of palm sugar, and describe the marketing flow of palm sugar. This research was conducted for two months, in the Education Forest. Data collection methods include field orientation, observation and interviews. Determination of the sample was carried out by census, namely 14 sugar palm farmers. The analysis was carried out descriptively qualitatively on the process of tapping sap, making palm sugar, and marketing flow. Meanwhile, quantitative descriptive analysis was carried out on the calculation of production costs and income. The results of this study illustrate that the flower bunches tapped are male flowers. The process of tapping includes the following activities: preparation, taking sap, making palm sugar. The results of tapping sap are generally used as raw material for palm sugar. Tapping the sap and making palm sugar is carried out for approximately eight months every year. The process of tapping nira carried out by sugar palm farmers in the location is still based on habits and experiences that have been passed down from generation to generation. The average production cost is IDR 7,026,552.-/year/family and the average income is IDR. 10,705,500.-/year/family, so that the average profit is IDR. 3,675,948.- per year per household. There are three marketing channels for palm sugar in the research location, namely: (1) Producers Directly to consumers (2) Producers to collectors to consumers (3) producers to collectors to the market and to consumers.

The tropical coniferous genus Dacrydium Lamb. is occurring with some species in various habitat types in Kalimantan, Indonesia. So far four species are recorded for that area. Even though the species are considered globally as Endangered and Least Threatened species by the IUCN, in Central Kalimantan the genus is under threat from pressures related to logging, fire and land conversion. Locally known as Alau, this genus prospers in a range of habitats from heath to deep-peat swamp forests in Central Kalimantan. Data from field plots across four sites in Central Kalimantan are used to compare variations in habitat and species composition where Alau trees are present. The results of the analysis show the wide range of habitat structure as well as species diversity where Alau tends to thrive. The characterization of these sites may be helpful in protecting and conserving Alau forest areas under social forestry and local forest management resource use plans.

Silkworm is an insect that can produce silk fiber at any step of life, one of them in the moth phase. There are still not many researchers who have researched pebrine and BmNPV disease detection in the moth phase. This research purpose was to find out pebrine and BmNPV disease detection on moth phase. This research was conducted from January 2021 to March 2021 with samples obtained from the Center for Social Forestry and Environmental Partnership, South Sulawesi in Bili-Bili, Gowa district. The data processing was done at the Laboratory of Biotechnology and Tree Breeding, Faculty of Forestry, Universitas Hasanuddin, Makassar. Data analysis was done using the descriptive analysis method by looking at the primer amplification of Pebrine disease and BmNPV in the silkworm moth phase. The detection of pebrine disease ad BmNPV from the two primers showed that from 12 moths studied, none of the moths detected either pebrine disease or BmNPV disease.

Published: November 2021

This study aimed to analyze the concentration change of Aluminum in the soil with addition of MycoSilvi and soil ameliorant in silica sand post mining soil media. There are three types of MycoSilvi, single or combination, added with soil ameliorant which tested on Albizia chinensis (Osbeck) Merrill. The experimental design used was a factorial design with two factors, MycoSilvi (M) consisting of four levels (M0 = without MycoSilvi; M1 = MycoSilvi type 1; M2 = MycoSilvi type 2; and M3 = MycoSilvi type 3) and soil Ameliorant (LC) consisting of four levels (L0C0 = without soil ameliorant; L1C0 = lime; L0C1 = compost; L1C1 = lime and compost). Data analysis used analysis of variance (ANOVA). The results showed that the combination of MycoSilvi and soil ameliorant decreased aluminum concentration from 7.70 to 0.10 cmol(+)/kg and increased pH from 3.20 to 5.67 were positively correlated with total biomass. Significant changes were shown in MycoSilvi type 3 with the addition of lime and compost (M3L1C1). Application of MycoSilvi type 3 (M3L0C0) gave equivalent response with application of lime (M0L1C0) to increased dry biomass, so that lime can be replaced with MycoSilvi type 3 (M3L0C0) to promote plant growth, especially biomass of plant.
