EFFECT OF THE CHEMICAL OF SOIL ON THE PRODUCTIVITY OF COCOA SPECIFIC WEST SULAWESI Harli 1) L Asrul 2), Baja S. 3), R Padjung4), R. Neswati 5) 1) Al Asyariah Mandar University, West Sulawesi 2,3,4,5 ) Hasanuddin University, Makassar Abstract Cocoa is the main plantation commodity which plays an important role in the Indonesian economy. In addition, cocoa is still the third largest source of non-oil and gas foreign exchange after rubber and palm oil. The area of cocoa plantations in Indonesia in 2015 reached 1. 722,315 ha. Cocoa bean production has continued to decline from 740,513 tons since 2012 to 656,817 tons in 2016. Cocoa is the main plantation crop in several regions in Indonesia, including West Sulawesi. However, cocoa farmers have various problems. One of them is low productivity. The average cocoa productivity is only 650 kg / ha / year. This productivity is still carried by the optimum cocoa productivity. One of the causes of low cocoa productivity is that cocoa plants are planted on inappropriate land. One of the land requirements that must be suitable is the physical and chemical of the soil. This research uses quantitative methods with a deductive approach This research was conducted in West Sulawesi Province in January-August 2020. The results showed that There is a correlation between Same of Basic Cations and cocoa productivity. The bases saturation (Ca, Mg and K) does not have a significant effect on the productivity of cocoa plants in the high productivity category. There is no correlation between pH H20 and cocoa productivity. pH H20 has a positive correlation with C-Organic, salinity, base saturation and the bases saturation.

Energy-efficient Building Design Aesthetic Model Related to Optimization of Solar Energy Utilization Nurul Jamala, Ramli Rahim, Taufik Ishak Department of Architecture, Faculty of Engineering, Hasanuddin University, Indonesia Abstract Optimizing the use of solar energy as a source of natural lighting in buildings is one way of saving energy. The aesthetic value of the building needs to be considered in planning an energy efficient building model. The facade model on the building envelope can reflect the aesthetic value of a building. The research objective is to analyze the aesthetic model of buildings by applying solar energy optimization. The research method is quantitative, namely by simulating the building facade model and then analyzing the simulation results. The simulation uses the ecotech program to determine energy consumption and light intensity in buildings. The research object is an office building, namely the Bank Mega Makassar Building which is located in a coastal area. The results showed that the aesthetic design model of the building affects the consumption of solar energy. The results showed that there was an increase in the average value of the illuminance level by 9-26% from the floor to the highest floor. The average value of the illuminance level on the 1st floor is 3347 lux and on the 7th floor of 5148 lux, so it can be concluded that the light distribution affects the height of the building. The vertical facade model on the building envelope has the highest illumination value compared to the horizontal, diagonal, vertical-diagonal and vertical-horizontal facade models, so it can be concluded that the facade model affects the distribution of natural light. The contribution of this research as a concept in planning a building with aesthetic value and energy saving in the study of natural lighting systems in buildings.

Relevant Indicators of Social Vulnerability during Response Phase Context of Flooding in Tebing Tinggi City, North Sumatra Indonesia Boboy Andika Harahap Griffith University, Queensland, Australia Abstract Indicators to reflect social vulnerability to flood vary among scholars. These variations tend to be developed primarily due to heavy dependency on the statistics data availability. Unless employing such predetermined indicators to assess the states of social vulnerability, scholars were less attracted to study what relevant indicators should be in assessing such social vulnerability. Apart from this gap, majority of the studies have overlooked the significance of time-frame contexts of flooding in determining the situation of social vulnerability. Consequently, many conducted the investigations without questioning the relevance of indicators in terms of time-frame contexts. This current study, accordingly, attempts to investigate relevant indicators of social vulnerability to flood with respect to response phase context. With the study area of Tebing Tinggi in North Sumatra, 76 indicators are tested using Likert scale of survey and Principal Components Analysis (PCA). As a result, 6 retained components produce 12 relevant indicators to reflect social vulnerability to flood during response phase- they are: Elderly, Female, Single parent families, Household or per capita income, Children, Poverty and deprivation, Dependency, Informal sector/day laborer, Slum dwellers, Male, Renters, and Unemployment.

Graduate School Building, Makassar, 90245. South Sulawesi, Indonesia *pramadania.agustine[at]gmail.com b) Griffith University, Nathan Campus, Queensland, Australia Abstract Following an oil spill in the western Java Sea, in July 2019, the issue of oil pollution has received heightened interest. More and more people in Indonesia are increasingly aware that environmental damage will be a serious threat to the sustainability of ecosystems and environmental services. Given that oil pollution does not only endanger the aquatic ecosystem but also the surrounding terrestrial ecosystem, it is important to encourage the involvement of stakeholders to contribute to efforts to prevent and/or minimize the impact of oil pollution in coastal areas that may arise in the future. Thus, since oil pollution is extremely harmful not only to aquatic ecosystems, but also terrestrial ecosystems, coastal management strategies are urgently required to minimize the impact of oil pollution in the future. The overall aim of this research is to provide recommendations for policy formulations that may be adopted by the relevant local government to protect coastal areas from sea water contaminated with oil. To achieve this objective, the operational objectives are: 1) to analyse the extent to which community perceptions of risk to oil spills affect their preparedness in the face of such events- 2) to formulate alternative strategies for the management of coastal areas threatened by oil pollution as part of an effort to maintain the sustainable development of the Java Sea coastline, specifically in this study, the Muara Gembong District. This research uses both qualitative and quantitative approaches, including Statistical analysis, Strength-Weakness-Opportunity-Threat (SWOT) analysis and Analytical Hierarchy Process (AHP). The type of data collected will be primary data and secondary data which are sourced from experts and agencies engaged in the management of the coastal and marine environments Keywords: environmental impacts- oil pollution- coastal development Share Link | Plain Format | Corresponding Author (Pramadania Agustine)

Assessing the Impact of Land Cover Change and Climate Change On Water Availability in Brantas River Basin, East Java, Indonesia Rohandi Prastiawan, ST- Dr. Christopher Ndehedehe (Griffith University)- DR. Roland A. Barkey (Hasanuddin University) 1. Universitas Hassanuddin 2. Griffith University Abstract The cumulative emissions of CO2 in the atmosphere have caused impacts on hydrologic variability. It decreases the precipitation rates and increases surface temperature. On the other hand, unprecedented rates of land cover change have increased stream-flow and evaporation in the watershed. The effect of both climate change and land-use change has become a significant issue in the Brantas Watershed, Indonesia. In this study, SWAT analysis will be performed to observe the correlation between climate change and the impacts of land cover change to the watershed and projected water availability in the future will be measured. The watershed has been classified into five major land cover classifications- forest, water, agriculture, settlement and open land from three different satellite images, 1998, 2008 and 2018. Temporarily, the land cover map has shown major change in forest area, which has decreased 30 % and Open land area has decreased 6%, while agriculture and settlement increased 23 % and 20 % respectively The aim of this study is to contribute to the disaster prevention and mitigation plan for the future, which can be adopted by policy makers, planners and other associated development workers.

Factor affecting July 13th, 2020 flash flood in Masamba Area, North Luwu, South Sulawesi Adi Maulana (a,b*), Iswandy Utama (a) (a) Centre for Diasaster Study, Hasanuddin University (b) Geology Department, Hasanuddin University Abstract The paper discussed the factor affecting flash flood that occurred on July 13th 2020 in Masamba Area, North Luwu, South Sulawesi. At least two major river catchment areas were severely hit by the flash flooding, namely Rongkong and Baliase catchment area. Based on a quick geological observation and a desk study on climatological data couple with a new satellite image interpretation, it is concluded that combination of geology, climatology and bad land use change, play an important role in triggering the flash flood in Rongkong and Baliase River catchment areas. Highly weathered granitic rocks, steep slope morphology and faults system developing in the upstream are some main geological factors that generating the widespread of numerous landslides in which contributing the accumulation of massive debris content in the river. Although rainfall average within three days prior to flooding suggest a moderate pattern (less than 100 mm/day) yet the duration and intensity of the rainfall had caused high volume of water discharge in some sub catchment areas, namely Radda and Masamba sub catchment areas (Baliase) and Binuang sub catchment areas (Rongkong). Spotted and uncontrolled land use change eventually provoke the massive flash flood especially in Rongkong River. Considering the geology and climatology factors affecting the flash flood will not be very easy to overcome in the near future, a comprehensive river upstream management should be implemented immediately to avoid any fatality. It is therefore highly recommended that structural and non-structural mitigation should be applied to mitigate the future disaster.

The characteristics of stomata and chloropyll content of Gofasa leaves (Vitex cofassus Reinw) based on the growth phase and canopy position S A Paembonan, S H Larekeng, S Millang Faculty of Forestry , Universitas Hasanuddin Abstract Stomata characteristics and chlorophyll content in leaves are the two main elements of leaf physiology factors that have a big role in determining the photosynthetic capacity of a tree. Knowledge of the physiological properties of these leaves determines the proper silvicultural treatment in the management of stands. This research aims to analyze the characteristics of leaf stomata and the dynamics of chlorophyll content based on the direction of the canopy and the growth phase of the tree as well as its relationship with the environmental factors where it grows. This research was carried out in 3 different locations, namely in Gowa Regency (153 m asl), Kajang (Bulukumba 76 m asl), and Makassar city (12 m asl). The research variables analyzed consisted of the number of epidermal cells, leaf stomata characteristic, and chlorophyll content of gofasa leaves. The highest average number of stomata was found in leaves exposed to sunlight in the east parts of the canopy with a total of 334,200 stomata/mm2 compared to shade leaves with 224,333 stomata/mm2, while the tree phase level was 265,566 stomata/mm2 compared to seedlings phase which were only 237,400 stomata/mm2. The highest leaf chlorophyll content was found in leaves exposed to the sunlights in the east canopy by 0.0252 m/L while those shade leaves containing 0.0208 mg/L. Likewise, leaf chlorophyll content is higher in tree level phase of 0.0235 mg/L while in the seedling phase it was only 0.0186 mg/L. There was a significant relationship between stomata characteristics and chlorophyll content in leaves with environmental factors. The higher the place to a height of 153 m above sea level, the number of stomata increases as well, and the higher the light intensity of a place is directly proportional to its chlorophyll content. Study of genetic can increase growth of plants by providing genotypes with a more efficient combination of physiological processes for a particular environment.

In vitro shoot multiplication of Morus nigra by combinations of plant growth regulators S H Larekeng, M A Arsyad, A Meliyana, M Restu Faculty of Forestry Universitas Hasanuddin Abstract Mulberry (Morus nigra L) is a dicotyledonous plant in the family Moraceae which often used for silkworms^ breeding. Mulberry propagation still uses conventional technology, such as cuttings and graftings. The problem of mulberry propagation is the low productivity of mulberry gardens. However, tissue culture is a technique of isolating plant parts in the form of organs, cell tissues, and protoplasms that is effective and efficient in order to get uniform and superior plants in a short amount of time. For mulberry growth, the right combination of the Plant Growth Regulator (PRG) in the form of Kinetin, IAA, IBA is needed. Data were analyzed using R-statistic software. The results showed that M6 media (MS + Kinetin 1.5 + 1 IAA) was the best combination of media for the number of shoots, leaf length, and number of roots, with 80% of live explant percentage. Propagation via tissue culture such as clonal propagation, organogenesis, and somatic embryogenesis in callus cultures followed by generation of shoots/plantlets represents a potential effective propagation method in the future.

Community Participation Against Disaster Risk in the Settlement Area of Lero Village, Pinrang Regency Mimi Arifin, Shirly Wunas, Pratiwi Mushar Hasanuddin University Abstract At present, the worrying global issue of coastal areas is its vulnerability to disasters. One of them is coastal abrasion. If it is left unchecked, the abrasion will erode parts of the beach so that sea water will inundate areas that were previously used as sand playgrounds or residential areas and shopping areas on the beach. In overcoming abrasion disasters, mitigation efforts are made to reduce the risk of existing disaster impacts by utilizing the participation of local communities. By involving the community in the entire process, disaster mitigation efforts can be planned and implemented effectively. Lero Village as one of the coastal areas in South Sulawesi, precisely in Pinrang Regency, is at risk of abrasion. The abrasion disaster risk on the coast of Lero Village causes the need for community participation in disaster mitigation efforts. The research objective is to determine the factors that influence community participation in the effort to mitigate the abrasion disaster in Lero Village.. Data collection was carried out through observation, interviews, and questionnaires. The data was analyzed by using SPSS iBM Statistics software with the Pearson correlation test analysis method. The analysis results show that external factors which are communication, social climate, opportunity to participate, and freedom of creation, have a strong and unidirectional influence on community participation in the context of disaster prevention and management.
