Abstract
The split ring resonator (SRR) and complementary split ring resonator (CSRR) which are popular metamaterial structures for energy harvesting applications has been investigated for its characteristics and performance potential through numerical computation. The results of investigation on the design of the double-T RF energy absorber show a good performance and can operate in multiband with a large bandwidth. The desired absorber device has been optimized by adjusting the physical dimensions in the SRR and CSRR metamaterial structures. By etching two SRR unit cells and six CSRR unit cells in the ground plane, the proposed antenna shows a good performance of the return loss, gain, and bandwidth parameters. Also, the reconfigurable absorber device can be maximized the potential for absorption of RF harvesting energy, both emitted by licensed and unlicensed RF communication devices. The antenna covers the frequency spectra of GSM900 Band, GSM1800 Band, WiMAX Band, and ISM Band applications, respectively as needed. This antenna is good for absorbing RF energy with a smaller antenna size of 72.25% compared to conventional antenna.

Abstract
Energy farces an important role in shaping civilization as a major input from various sectors of life. For Indonesia, the management and utilization of energy will determine the likely existence as a nation forward in the future. This research used a quantitative methodology which is the chosen method is system dynamic simulation. The system dynamics model is the shape and energy utilization in Indonesia to achieve a degree of energy security with complex variables covering economic, social and environmental as well. The model simulation investigates the implications of the use of fuel to the economy and how to find a model of low-carbon energy sustainability in the energy mix policy in Indonesia. The model explores the relationship between population, fuel consumption, fuel production, fuel import, and emissions resulting from the use of fuel. This model will be used as the basis for the simulation scenario of Business As Usual (Base case) so that the visible trend of each variable and how interventions should be done. The interventions that are chosen namely structural intervention where included gas and geothermal as the additional energy resources. Then, a Hypothesis that would be tested in this research is the reduction of CO2 emission and fossil fuel import as the feedback of energy mix policy. The result shows that mix energy policy can reduce the CO2 emission at least 9% on average along the simulation period. On the other hand, the import of fossil fuel import can be reduced averagely by up to 27%. Therefore, the mix energy policy is strongly feasible to be implemented and developed in the future.

Abstract
The main objective of this research were to analyze acreage response of agricultural investments in Jambi soybean production. Study was conducted in Jambi province using secondary data from 1986 – 2017. Acreage response functional form was used to explain and analysis problem of acreage response of soybean production in Jambi. Study was done in 2018. A method of measuring price expectation for analyzing acreage response is used when the influence of price support and market phenomena varies with market conditions. It assumes that the effect of changes in government policies because similar programs for acreage control and price support are likely form of future policies. A method of evaluating support and acreage restriction is developed and tested to see the impact of changing government programs. The results showed that when the support price is much below the expected market price, the truncation effect is negligible and the price support program has only a limited impact on acreage decisions. Alternatively, as the support price levels, the truncation effects become larger, and the resulting impact on acreage decisions is more pronounced.

Abstract
The iconic symbiosis with clownfish is not the only sea anemone-fish association. Several tropical sea anemones provide microhabitat for the Endangered (IUCN Red List) Banggai cardinalfish Pterapogon kauderni. Microhabitat loss from declining sea anemone populations is a serious threat to native P. kauderni populations or evolutionarily significant units (ESUs). One measure advocated to maintain and rehabilitate these P. kauderni ESUs is to restore microhabitat abundance. The objective of this study was to evaluate the feasibility of asexual propagation of wild anemone broodstock with subsequent release. Two species with which P. kauderni commonly associates (Heteractis crispa and Entacmaea quadricolor) were identified through field surveys. Parent anemones were bisected, cutting through the centre of the oral disc. Propagules (half anemones) were placed in empty clam shells as hard substrate. Treatments provided different levels of protection from potential predators, in aquaria (P. kauderni present/absent), concrete tanks (P. kauderni and Diadema urchins excluded/not excluded) or in a net cage on natural substrate (fish and invertebrate fauna including P. kauderni and Diadema setosum). The cut edges of sectioned anemones joined together within seconds, with wounds typically healing in around 7 days and joins hard to see after 3-4 weeks. Growth was faster and long-term survival higher in the net cage compared to tanks for uncovered and covered anemones. The results indicate potential for this propagation method in the context of P. kauderni conservation, and suggest sectioned anemones should be moved to the natural rehabilitation areas once capable of adhering firmly to hard substrate

Abstract
Abstract. Heavy metals such as Cu, Pb, and Zn, have been reported to be the main contaminants found in post-mining areas. Settling pond treatment systems have been applied to the base metal mining area at Sangkaropi, before being discharged into the Koyan River through the agriculture area. This study aims to conduct an assessment of heavy metal contamination in areas impacting base metal mining. The material tested was sediment deposition in the Koyan River which is a sensitive indicator for monitoring contaminants in the aquatic environment. River sediment sampling is categorized into three areas, namely the first area upstream before the mining location, the second from the mining area to settling pond and the third area after settling pond to the agriculture area. The heavy metal test method uses the Atomic Absorption Spectrophotometry type Buck Scientific 205 version 3.94C. The assessment is performed based on the value of contamination factor (Cf) to explain the process of contamination toxic substances to the environment, Geo-accumulation Index (Igeo) to describe the enrichment of heavy metal concentrations above the baseline level and ecological risk factors (Er). The results of this study represent that in the first area, the assessment of Pb metals is low, Cu and Zn metals are unpolluted to low. In the second area, the Pb metal has values classified as strongly - extremely polluted, Cu (low - moderately polluted), and Zn metals (unpolluted - low). In the third area, Er values on all metals are classified as low polluted and Cf and Igeo values are unpolluted. The results of the assessment of the distribution of heavy metals Cu, Pb, Zn will be able to assist policies to direct land use in areas impacting mining and interdisciplinary studies to assess environmental health impacts.

Abstract
Cocoa plantations have ecological functions as carbon sinks and depositors. Cocoa absorbs CO2 during photosynthesis, then converts it to carbohydrates by storing it in the form of biomass in roots, trees and leaves. The purpose of this study was to determine the carbon uptake of cocoa trees and tree growers, undergrowth, necromasses, carbon uptake at the root and carbon uptake in soils in several cocoa planting systems implemented in Bantaeng Regency, South Sulawesi. Sampling is done by purposive sampling method with the basic consideration of the type, density and cropping system applied. Biomass estimation is used non destructive method by measuring diameter at breast height (DBH, 1.3 m) and height of cacao and shade plants. Carbon storage in cocoa plants is distinguished by several cropping systems, namely K1 (monoculture harvesters) and K2 (multistrata harvesters). The results showed that carbon reserves in Bantaeng Regency were 32.38 tons/Ha.

Abstract
Supply chains approaches can be used to solve cayenne pepper-s problems such as unpredictable supply, price fluctuations, uncertainty in production, extreme weather, distribution channels, and price stabilization. Supply chain-s success can be seen from the level of performance. Performance measurement is needed as an approach in order to optimize supply chain networks. The research aims to examine the structure and performance of cayenne pepper supply chain. The study was conducted in Gorontalo and was using survey methods. Data analysis was using descriptive and marketing efficiency analysis. The results showed 1) The structure of the cayenne pepper supply chain in Gorontalo Province consists of seven distribution channels. Sale of cayenne pepper by farmers through collectors (40 percent), wholesalers (26.67 percent), market traiders (10 percent), and retailers (23.33 percent). The primary members of the cayenne supply chain consist of farmers, collectors, wholesalers, out-of-town traders, market traders, retailers, consumers and agroindustries. The secondary members are farm shops, banks, transportation service providers, the Agriculture Service and information media. 2) The most efficient distribution channel is channel six because the smallest marketing efficiency value is 3.17 percent. The cayenne pepper-s market in Gorontalo runs inefficient because it has a price transmission elasticity value of 1.11 (Et> 1). It means the rate of change in prices at the consumer level is greater than the rate of change in prices at the farmers level.

Abstract
Agricultural land is the main and unique factor of agricultural production, because it is difficult to replace in an agricultural business process. This research is intended to conduct a spatial study of changes in land use, especially paddy fields and the suitability of spatial use with the regional spatial plan (RTRW). In this study an analysis of land use change was carried out by comparing multitemporal land cover data (time series), and the suitability analysis of spatial use by comparing actual land cover data with the direction of spatial use specified in the RTRW document. Both of these analyzes were carried out by overlaying maps using GIS (Geographic Information Systems) spatial data processing software. The results showed that within 10 years (2007-2017), an increase in total area occurred in the plantation (1.4%), built land (41.37%), dry land/fields (1.97%) ), and lake/body of water land use class (11.14%). While the area of forest, paddy fields, and shrubs is reduced by 0.12%, 5.09% and 6.68% respectively. The results of overlaying actual land use maps with spatial pattern maps on Gorontalo Regency RTRW show that most (65.67%) land use in Gorontalo Regency is still in accordance with the direction of spatial use which has been specified in the RTRW. Whereas 34.13% of other land uses were identified as not yet suitable (30.57%) and not suitable (3.55%) with the RTRW. Land use that is not yet suitable is still possible to change to adjust the spatial Plan in the future. Regarding paddy fields, the land use suitability matrix with the RTRW shows that 86.18% of the paddy fields in Gorontalo Regency are in accordance with the RTRW (located in the allotment of wetland agriculture areas), while the remaining 13.82% are not in accordance with the RTRW. There is also the potential for new paddy fields with a total area of 6,293 hectares.

Abstract
Sungkai wood (Peronema canescens Jack) is one of prominent materials used for production of furniture and other decorative elements in Kalimantan and Sumatra due to its beautiful fiber and color, and also its fairly smooth texture. Since of massive production, the waste resulted from the processing of sungkai wood are very abundant. Utilization of sawdust or wood shavings of sungkai still generates a relatively low value. In order to increase the value of sawdust and wood shavings of sungkai, this research was aimed to identify the characteristics and performance of bio-briquette produced from the sawdust and wood shaving of sungkai. This research was performed by evaluating the characteristics and performance of bio-briquettes produced from three concentrations (10%, 15%, and 20%) of glue material made from tapioca starch. The results show that, except of the volatile matter, all parameters of the characteristics and performance of the tested briquettes comply with the Indonesian National Standard (SNI) of briquette product. The characteristics and performance of the tested briquettes at the lowest levels are follows: water content (4.52%; SNI: max 8%), ash content (4.36%; SNI: max: 8%), volatile matter (42%; SNI max: 15%), density (0.46 g/cm3; SNI: 0.45-0.85 g/cm3), combustion time (0.14 g/min), ignition time (2.5 second/g), and calorific value (5.889 kcal/kg; SNI: min 5000 kcal/kg). It requires optimization on the carbonization process in order to reduce the volatile matter.

Abstract
One of the most widely used construction materials is concrete. Concrete technology is currently developing, one of which is looking for alternative materials concrete forming. This research focuses on the use of slag as a fine aggregate in concrete, especially in environments containing sulfuric and chloride acid. Observations were made by testing compressive strength, split strength, and flexural strength, with 171 cylindrical specimens and 27 sample beam specimens. The test results show that the relative percentage of compressive strength of normal concrete on H2SO4 curing against normal curing decreased 1.85% and 2.58% on HCL curing. The biggest reduction in the percentage of concrete compressive strength was found in 30% slag substitution with a value 8.42%, while the percentage reduction in the relative strength of the split strength concrete is found in concrete with a slag substitution of 35% with a value 9.26%. As well as the decrease in relative percentage of flexural strength was found in 35% slag substitution with a value 12.84%. Although there is a decrease in each characteristic of concrete, slag material can be used as a constituent for concrete under environmental conditions of sulfuric acid and chloride acid.

Abstract
Development of dairy cows outside Java is an alternative effort to increase population and national milk production. Production produced by dairy cows in the form of milk production, livestock production and production of livestock waste into biogas and fertilizer. The presence of a dairy farming business starting from input, process, and output has formed different modes of production. This study aims to analyze the coexistence of dairy farming modes of production that support utilization in producing biogas as a renewable energy source. The location of the study was conducted in Enrekang Regency from April 2018 to May 2019. Data collection through observation, in-depth interviews, documentation, and triangulation then the data were analyzed qualitatively. The results show that dairy farming can coexist with Dangke production and derivative products, the business of selling calves and unproductive cattle as well as farm waste processing business in the form of biogas both controlled by subsistence, commercial and pre-capitalist modes of production without mutually deadly. This shows that the capitalists who grew up in the dairy farming business in Java are different in Enrekang Regency.

Abstract
Acid mine drainage (AMD) contains high concentration of various heavy metals and have low pH levels. In this study, the comparison between the use of natural zeolite and synthesized zeolite for Cu2+ removal in AMD was conducted. The adsorbent of natural zeolite was prepared through a chemical activating method by adding NaOH. While, synthesized zeolite was prepared from coal fly ash using a two-step method, fusion and hydrothermal process. The AMD used in this study was artificial designed with the concentration of Cu2+ 100 ppm and pH ± 3. The adsorption experiment was carried out using batch method to observe the influential parameters such as adsorbent dosage, contact time, adsorbent isotherms and kinetics. The result from this study is expected to provide better alternative adsorbent between natural zeolite and synthesized zeolite for heavy metal removal in waste water. Furthermore, both natural zeolite and synthesized zeolite have a great potential as a sustainable and economical material for heavy metal removal in waste water.

The challenge for the success of small and medium enterprises in Indonesia is increasing competition that demands adaptation to environmental changes. SMEs fish processing for boneless frozen milkfish in Pinrang Regency has a production capacity of 150 tons per year, potentially producing solid, liquid or gas waste. The purpose of this research is to analyze the potential of SMEs fish processing waste and its utilization in supporting the sustainability of production. The study was conducted in Pinrang Regency from December 2018 to April 2019 with a qualitative descriptive approach. Data collection through field observation, interviews, and documentation. The results showed that the potential of waste produced by 20-30 percent was used as food, feed and fertilizer products. The diversification of the main products into "fish meatballs" and "fish crackers" increases competitiveness and reduction of solid waste. Solid waste is also used to produce by-products in the form of "shredded milkfish" and "fishbone sticks". SMEs fish processing has dynamically applied the concept of clean production in handling and utilizing waste. Waste management has reduced the impact on the SMEs fish processing environment. The implementation of clean production has increased production capacity, product diversification, guaranteed product quality, customer satisfaction, and the welfare of owners and workers. The strategy for handling and managing waste has optimized added value and supports the improvement of competitiveness and sustainability of production.
