Published: December 2021

Abstract
The fishing port as the basis for the capture fisheries sector has a very important role in the national economy. Since the inauguration in 2016 until now, Untia Makassar Fishing Port has not shown an increase in activity as expected. This research objective is to make an inventory of the regulations related to the Untia Fishery Port Management Policies and how is the implementation of the Untia Fishery Port Management Policies. This research uses a descriptive method with a qualitative approach. The sampling technique used was purposive sampling. The method of data collection is done by interview, participatory observation, documentation, and questionnaire. The results show that the Decree of the Minister of Marine Affairs and Fisheries of the Republic of Indonesia Number 74 / KEPMEN-KP / 2016 concerning the Management of Untia Fishery Ports has not succeeded in becoming a tool in increasing fisheries activities. Therefore, it is necessary to coordinate immediately with the Ministry of Administrative Reform - Bureaucratic Reform (Kemenpan-RB) so that the nomenclature of Untia fishery port managers can be immediately determined so that additional human resources and budgeting resources can be added. The efforts must be made so that policy implementation can be maximized in the community, namely (1) local government support for the initiation of the 30 GT ship to facilitate it to the fishery port for use and (2) local government support in the form of regulations for industrial entrepreneurs both in the ship supply industry as well as the marketing and distribution of fishery products to grow the fishery industry at the port of Untia.

Abstract
Widely distribution of serpentinization rock especially ultramafic rocks in Sebuku Island, South Kalimantan, primarily in the concession area of PT. Sebuku Iron Lateritic Ore (SILO). Some representative samples were taken from the site and analyses the level of serpentinization to determine the characteristic of the rocks. The ultramafic rocks in the study area consist of peridotite with a low to high degree of serpentinization to serpentinite. The pseudomorph textures are shown like mesh, bastite, blades/flaky, hourglass, vein, and veinlet. Serpentine occurs as lizardite, chrysotile, and antigorite. Geochemical analysis like XRF (X-ray fluorescence) was used to find out the composition element. By this analysis, the wt.% of the element will be shown and determine the level of Nickel (Ni), and Iron (Fe), and the level of serpentinization also. The Serpentinization levels are affecting Ni and Fe. The higher the serpentinization level, the higher Fe (wt.%), whereas the higher level of serpentinization, the lower Ni (wt.%).

Abstract
Coral reefs in Spermonde waters have experienced degradation as a result of the increasing turbidity in these waters. This research was conducted on Kayangan Island, Samalona Island and Kodingareng Keke Island, Spermonde Islands, Makassar City. The purpose of this study was to determine the percentage of coral cover, types and the how much the turbidity of the waters influence the coral. The researcher measured the coral cover using Underwater Photo Transect and processed the data using CPCe software. The levels of turbidity were taken at three locations and examined in the laboratory and the other parameters were measured on site. The correlation between turbidity and coral cover was analysed by regression analysis method. Based on the regression results, the turbidity level has a negative effect on coral cover. The level of turbidity is higher on Kayangan Island with 0.89 NTU with a cover percentage of 4.95 %, Temperature of 30°C, Salinity of 30 ppm, DO of 5.44 mg/l, pH 7.8 and the species found were Porites and Faviidae. Samalona Island is 0.43 NTU with a percentage of coral cover of 14.08 %, Temperature of 30°C, Salinity of 30 ppm, DO of 5.44 mg/l, pH of 7.7 and the most common types are Acropora and Fungiidae. Kodingareng Keke Island has a turbidity value of 0.32 NTU, Temperature of 29°C, Salinity of 30 ppm, DO of 6.08 mg/l, pH 7.3 and the most common coral species, Fungiidae. Higher levels of turbidity in Kayangan Island will result in the death of certain coral species (unable to adapt) and will also have an impact on the percentage of hard coral cover.

Abstract
Supplies of fresh water in everyday life has increased, but the smaller the potential sources of water so we need to think of alternative uses of water for concrete construction work. This study aims to compare the compressive strength of concrete using sea water and fresh water with water cement ratio of 0.37. An experimental research was conducted by making specimens of concrete cylinder with a diameter of 150 mm and height of 300 mm. The study used specimens of concrete using sea water and fresh water. There were 32 specimens for each kind of concrete. The treatment of each specimen used sea water and fresh water in accordance with the type of mixing water. The immersion periods were 1, 3, 7 and 28 days. Mechanical testing of concrete was conducted by testing the compressive strength and elasticity, while the testing of concrete microstructure was conducted by using X-Ray Diffraction (XRD) and Scan Electron Microscopy (SEM). The results revealed that in the 28-day immersion period. The compressive strength values of the sea water concrete and fresh water concrete were 44.88 MPa and 44.03 Mpa respectively. The difference of compressive strength in the two types of concrete was not significant. The result of microstructure test in the 28-day period revealed that in the sea water concrete, there was a formation of Friedel’s salt (3CaO.Al2O3.CaCl2.10H2O) of 7.71%, tobemorite (3CaO.2SiO2.3H2O) of 58.66% and calcium hydroxide (Ca(OH)2) of 6.18%. In the fresh water concrete, there was a formation of tobermorite (3CaO.2SiO2.3H2O) of 51.35%, and calcium hydroxide (Ca(OH)2) of 22%. There was no formation of Friedel’s salt in the fresh water concrete because there was no mutual reaction between chloride and calcium hydroxide elements. From the regression analysis, showed that the difference of microstructure compressive strength differences caused by differences in the microstructure of the content of the two types of concrete.

AbstractOne of the fundamental problems faced by the province of South Sulawesi is the factor of accessibility, so the role of bridges is quite important. For this reason, the budget planning for standard bridge construction projects also needs to be efficient in terms of preparation and accurate in terms of budget. The Cost Significant Model is one of the total construction cost estimation models that relies more on the prices that have the most influence on the total project cost as the basis for estimation. In general, this study uses data from steel frame bridge construction projects in South Sulawesi Province to formulate a mathematical model with linear regression analysis so that it can be used in the process of estimating similar projects going forward. The Estimation Model which is formed from the regression analysis and the Cost Significant Model in this study, namely; Y = 3.884 (X7) + 0.989 (X8) - 65515.372. With; Y = Estimated Total Cost (Rp/m); X7 = Reinforcement Work Cost (Rp/m); X8 = Steel Frame Structure Work Cost (Rp/m). Where this model can explain 99.7% of the total project cost with a cost model factor of 1.038. The level of accuracy (percentage error estimate) of the estimation results of the Cost Significant Model in this study ranges from - 1.46% to +2.45%.

Abstract
Tidal swamps which are widespread in lowland areas have the potential to be used for agricultural activities. The amount of rain potential available in this type of land can be used to supply water for irrigation purposes so that plants grow optimally. However, the tidal potential especially on the peat swamps area may have a negative impact, namely the occurrence of nutrient leaching from the soil, which is harmful to plants. Rasau Jaya, a tidal lowland area with peat swamp soil characteristic, is an area allocated for rice and corn cultivation. The study was conducted with the aim to determine the physical potential and constraints of land and water management in Rasau Jaya for the cultivation of both types of plants. This research was conducted through field observations and measurements as well as laboratory tests and model scale to evaluate the characteristics of existing land quality based on Land Suitability Classification by the Food and Agriculture Organization (FAO). The result of this study shows that characteristics of water availability in Rasau Jaya is classified as Class S1 Highly Suitable for rice and corn crops, while existing conditions of land in Rasau Jaya III are generally classified in the S2 class Moderately Suitable for rice and corn crops. Appropriate land management is needed to increase land productivity for the cultivation of the Rasau Jaya’s assigned priority crops.

Published: December 2021

Abstract
Electric vehicle (EV) becomes an important option to overcome limited resources of fossil energy resources and to reduce side effects of Internal Combustion Engine Vehicles (ICEV) on the environment and health. However, the implementation policy of EV needs to apply carefully to make this policy sustainable and to minimize its side effects. Therefore, the Government of a country plays a significant role in leading and support the implementation of EV with policy and regulation. This paper reviews policies of Electric Vehicles (EV) in South Korea and Indonesia. The main objective of this review is to evaluate the strengths and weaknesses of the policies implemented in those countries. Three main aspects are elaborated, i.e., the main policy, the technology, and the private sector implementations. This paper also develops recommended policies and actions that could be done in Indonesia by reflecting on the EV policy in South Korea.
Minimizing Power Peaking Factor of BEAVRS-based Reactor Using Polar Bear Optimization Algorithms
Authors: Amatullah Amila , Agung Alexander , Arif Agus 
Published: December 2021

Abstract
Fuel loading pattern optimization is a complex problem because there are so many possibilities for combinatorial solutions, and it will take time to try it one by one. Therefore, the Polar Bear Optimization Algorithm was applied to find an optimum PWR loading pattern based on BEAVRS. The desired new fuel loading pattern is the one that has the minimum Power Peaking Factor (PPF) value without compromising the operating time. Operating time is proportional to the multiplication factor (k

eff
). These parameters are usually contradictive with each other and will make it hard to find the optimum solution. The reactor was modelled with the Standard Reactor Analysis Code (SRAC) 2006. Fuel pins and fuel assemblies are modelled with the PIJ module for cell calculations. One-fourth symmetry was used with the CITATION X-Y module for core calculations. The optimization was done with 200 populations and 50 iterations. The PPF value for the selected solution should never exceed 2.0 in every burn-up step. Out of 28 solutions, the best optimal fuel loading pattern had a maximum value PPF of 1.458 and a k

eff
of 0.916 at day 760 of calculated time (corresponding to a cycle length of 479 days). Therefore, the maximum PPF value was 27.1% lower than the safety factor, and the same operating time as the standard loading pattern has been achieved.

Abstract
The mesoporous gamma-alumina is a good material for metal adsorption. Its textural properties are excellent, mainly for molybdenum-99 radioisotopes adsorption as part of 99Mo/99mTc generator in nuclear medicine. In this work, we have prepared mesoporous gamma-alumina by sol-gel treatment in the presence of glucose as a soft template. The molar ratio of reactant (water: aluminium isopropoxide(AIP)) was applied in the high and low ratios (150:1 and 25:1). The resulted mesoporous gamma-alumina was investigated using characterization analysis of X-ray diffraction, Nitrogen adsorption-desorption, and FTIR. The results indicate that the mesoporous gamma-alumina in the high molar ratio of water to AIP had a higher surface area and better crystallinity than the low molar ratio of reactants. Furthermore, in the Mo adsorption test, the mesoporous gamma-alumina with the high molar ratio posed a higher Mo adsorption capacity up to 55.69 mg Mo g−1 adsorbent. In the future, the molar ratio of reactants should be tuned in the range of around 150:1 to obtain the optimal Mo adsorption capacities of the resulted mesoporous gamma-alumina using the glucose template.
Modelling Electric Energy Availability Toward Popupation Growth and Land Conversion in Padang Lawas Regency
Authors: Siregar Ahmad Munawir , Lusiana Lena , Utami Irza , Fakhruddin Muhammad 
Published: December 2021

Abstract
Electricity consumption in Padang Lawas Regency has increased every year, namely 59,962,000 kWh in 2018, and reached 74,060320,5 kWh in 2020. This increase is in line with the population growth rate so that it also has an impact on land availability. Forecasting electricity consumption absolutely must be done because it greatly affects the distribution and availability of electrical energy. There are three problems related to electrical energy resources. First, the availability of electricity will decrease as demand increases. The second is the increase in population which has an impact on improving the quality of life of the community and the availability of electricity. Third, the increase in land conversion is increasingly massive, causing population density and energy needs in the region to increase. For this reason, it is necessary to project the need for electrical energy for the population and land conversion in Padang Lawas Regency in 2021-2050. The objectives of this study can be used as a basis and choice for policy and strategy making in regional development planning by the Padang Lawas Regional Government. This is done so that the problem of electricity availability can be resolved. This research was conducted using the PowerSim Studio 10 application by simulating a dynamic system model involving several variables that influence each other. The results showed that population variables affect land requirements and total energy consumption. Analysis of electricity availability in Padang Lawas Regency until 2050 will experience an increase in electricity consumption accompanied by an increase in population and land conversion. Based on the results of the simulation scenario, the availability of electricity in Padang Lawas Regency can meet the total electricity consumption needs until 2050, either with or without intervention.
Determining policy recommendations towards electric vehicles incentives in Jakarta using AHP-Entropy
Authors: Radevito Arighi , Putri Utami Dannya Maharani 
Published: December 2021

Abstract
One solution for diminishing carbon outflows is to provide electric vehicles (EV), which can help the sustainable development of the ecosystem in an environmentally way. Jakarta, as a capital city with high levels of pollution, has forced the government to recognize the need for policymakers to correct environmental failures through effective policy solutions. To support policy-driven adoption of EV, incentives shall be given to stimulate EV users. Current regulations have not yet explained regulations for EV’s, direct and indirect consumer benefits, infrastructure for charging, and complementary policies. This paper will compare the world’s best EV policy which will determine the main policy criteria to be developed for Jakarta’s regulation using the analytical hierarchy process and entropy method in giving scaled preferences of sets of standards and alternatives with acceptable inconsistency. AHP is used to determine initial subjective weights from experts, while then entropy will enhance AHP’s weights into objective weight. This study shows that charging infrastructure is the most influential criterion among other criteria followed by consumer incentive, both direct and indirect, complimentary policies, and regulatory incentives. Therefore, it is highly recommended that Jakarta’s government develop EV’s incentive policy in detail as the order above.
Impact of natural gas pricing policy for energy security and macroeconomic resilience: A literature review from global perspective
Authors: Putriastuti M A C , Hanita M , Yusgiantoro P 
Published: December 2021

Abstract
Indonesia’s government has targeted 24% of natural gas in the national energy mix by 2050. However, one of the main problems in Indonesia’s natural gas development is the price mechanism. Unlike many countries, Indonesia’s natural gas market, including its pricing, is still heavily regulated and subsidized by the government. The low natural gas price has damaged the investment climate and slowed the natural gas development in the country. An overview of the global natural gas market evolution, as well as a comprehensive analysis of natural gas market transformation from China and Malaysia, were presented in this paper. The wider gap between supply and demand of natural gas and the increase of the LNG market in Asia have pushed China and Malaysia to reform their natural gas market into a liberalized system. This provides an insight to examine Indonesia’s natural gas pricing policies. The highly regulated market often fails to provide the actual cost of supply, leads to underinvestment, and causes a natural gas shortage in a country. Natural gas pricing policy transformation is mandatory to ensure supply stability and keep up with the global natural gas market dynamic. The transformation should be implemented gradually to give natural gas producers and end-users enough time to adjust to the regulations. In the end, gas-to-gas competition should be set as the long-term goal to allow retail competition in Indonesia’s natural gas market.
