Abstract
ABSTRACT Indonesia has a remarkable biodiversity that has been widely processed into traditional medicine. One of the plants that efficacious as a medicine is cherry. Cherries are efficacious as antioxidants, type 2 antidiabetes, analgetic, and antibacterial, because it contains flavonoids, saponins, and tannins. Sulaiman in 2017 examined the antibacterial properties of cherry leaves against the colony of Streptococcus viridans, but no one has examined the inhibitory test of cherry leaves for Streptococcus mutans. The purpose of this study was to determine the inhibitory test of cherry leaf extract against Streptococcus mutans. This research is purely experimental. The first stage of the study was extracted from cherry leaves, the second extract of cherry leaves was tested for its inhibitory power against Streptococcus mutans. Extracts were made in 4 groups namely 3 test concentrations namely K1 (15%), K2 (30%), and K3 (60%), and K0 as the control norm. After the cherry leaves extract was made, it was evaluated. Then tested the inhibition against Streptococcus mutans by diffusion method on blood agar media. Data analysis with one-way ANOVA with p value <0.05. The conclusion is the third concentration of cherry leaves extract gives inhibitory power against Streptococcus mutans and the best is K3 of 13.00 mm.

Abstract
The Constitution of the Republic of Indonesia guarantee the fulfill of the right of every person to develop himself by benefit from the development of technology and science for human welfare. The rapid advance of technology and science is certainly unavoidable but it must be utilized and used to optimally for the progress and welfare of humanity. Various benefits of advances technology have been felt both directly and indirectly. Today, the development of advances technology is increasingly echoed by the presence of the 4.0 Industrial Revolution. Indonesia has seen a variety of opportunities offered by the presence of the 4.0 Industrial Revolution. However, the presence of utilizing these advances technology can also have a negative impact, especially in the dimension of Corruption which is currently growing with various mode of crime and their interests. The potential for the occurrence of Corruption in the development of the 4.0 Industrial Revolution-s era must be carried out accurately and immediately in the form of policies in the field of prevention and eradication. The Corruption Eradication Commission (CEC) as a state agency given the authority to eradicate Corruption needs to have effective and efficient strategies, not only in the area of eradication, but also the application of policies in preventing Corruption. Corruption Prevention Policy can be used by the CEC by utilizing advances technology in this current 4.0 Industrial Revolution. Corruption Prevention Policy in the era of 4.0 Industrial Revolution will assist the CEC in carrying out prevention efforts so that the CEC-s workload in taking action to eradicate Corruption can be more optimal.

Abstract
The Randu Kuning Porphyry Cu-Au prospect area is situated at Selogiri district, Wonogiri regency, Central Java, Indonesia, approximately 70 km east of Yogyakarta city. The area is a part of the East Java Southern Mountain Zone, mostly occupied by both plutonic and volcanic igneous rocks, volcaniclastic, silisiclastic and carbonate rocks. Magmatism-volcanism products were indicated by the abundant of igneous and volcaniclastic rocks of Mandalika and Semilir Formation and many dioritic intrusive rocks of the Late Eocene-Early Miocene magmatism. Porphyry Cu-Au and intermediate sulphidation epithermal Au-base metals mineralisation at Randu Kuning have strong genetic correlation with the magmatism-volcanism processes. The mineralized dioritic intrusive rocks at the area, are distributed at the centre of the depression of an ancient volcanic crater. There are many intermediate sulphidation epithermal prospect area sourrounding the Randu Kuning porphyry Cu-Au. Most mineralizations both porphyry and epithermal environments are associated with the present of quartz- sulphides veins, but not all porphyry vein types contribute in copper and gold mineralization. The early quartz-magnetite veins (particularly A and M vein types) generally not contain Cu-Au or barren, while the later sulphide bearing veins such as quartz-sulphides (AB type) veins, chalcopyrite-pyrite (C type) veins, quartz-sulphides-carbonate (D type) veins are mineralized. Mineralization contain copper and gold deposits in range at about 0.66-5.7 g/t Au and 0.04-1.24 % Cu. Whereas the epithermal level, mineralization mostly related with the present of pyrite+sphalerite+chalcopyrite+quartz+carbonate veins and hydrothermal breccias. The epithermal veins and breccia lead to the occurences of silver, zinc and lead mineralization, it commonly contain around 0.4-1.53 g/t Au, 0.8-8.5 g/t Ag, 0.17-0.39% Cu, 0.003-0.37% Zn, 00089-0.14% Pb. In porphyry environment, copper and gold are likely transported together as chloride complexes (CuCl0 and AuCl2-) in magnetite stability field. The chlorite complexes then react with existing magnetite to produce free gold and chalcopyrite. On the other hand, the epithermal environment, gold and copper usually are transported in a different ion complexes. Au is transported as the thio complexe [Au(HS)2-; Au2(HS)2-S2- and HAu(HS)2-] in phyrite stability field, while Cu is preferably transported as chloride complex in the hematite stability field.

Abstract
Rice is a staple food for most of the population in Maros. Therefore, Maros is one of the rice producer regions in South Sulawesi. However, nowadays Maros experienced an intensive conversion of agricultural land to infrastructure development that leads to a decrease in rice production and affects food security in the future. To ensure that rice production in Maros can increase in the coming year, forecasting is needed for the next few years. This research aimed to describe the development of rice production in Maros from 2001 to 2022. The data used in this research were secondary data between 2001 and 2017 from Maros statistics. This research was a descriptive qualitative and quantitative research using Microsoft Office Excel and Minitab 17. The results showed that the development of rice production in Maros fluctuated and tended to increase every year. Based on the projection result, the rice production will have a surplus from 2020 to 2022 if the harvested area and productivity could increase.

Abstract
Arabica coffee owned by Toraja especially North Toraja is very distinctive with the aroma and flavor produced so that it becomes its own attraction in the hearts of coffee enthusiasts everywhere. But behind the taste and aroma that is very unique there are many problems faced by Arabica coffee farmers in Toraja in particular. This study aims to analyze the potential of North Toraja Arabica coffee agribusiness, which is then followed by studying the benefits that can be done by using the concept of organic farmers to create an appropriate strategy to improve quality in Arabica coffee agribusiness competition. Data taken using observations and direct interviews in the form of a questionnaire to farmers that includes how much can be produced each harvest season, and the price received each sell the harvest to collectors, companies, and several parties who participated in this research. Primary data used in this study are quantitative and qualitative data. The results of this study indicate that the Arabica coffee owned by Toraja has the potential, farmers as producers have a very big role in improving the performance of Arabica coffee development programs. However, observations show that policies in developing human resources in rural areas, especially in terms of farmers quality and skills, are relatively not working as expected. To reduce the level of dependence of farmers to traders, it is necessary to strive for financial institutions that are able to provide capital needs to farmers in a fast time without complicated procedures. Therefore farmers have alternatives to choose marketing channels that can provide better prices.

Abstract
This study uses a library approach and field research. The library approach is carried out by reading theories related to land values from the literature study and used to obtain secondary data. Meanwhile, field research was carried out by observation to find out and document land use in the city of Makassar. The analytical method used is descriptive quantitative and qualitative to describe the land value of the distance between Makassar City and land use. Besides, spatial analysis is also used to interpret the land value of Makassar City based on the Bid-Rent Curve in the form of maps of distance and land use. Moreover, correlation analysis is used to determine the relationship between distance and land use to land value. The results of the study through the analysis stages above show the value of land in the Makassar City is influenced by distance, where the closer to the city center the higher the land value and the farther from the city center, the lower the land value. Also, land use also affects the land value of Makassar City, wherein this study, the most critical land use is commercial land. This shows that there are conditions in accordance with the theory of Rent-Bid Curve.

Abstract
The Study has been conducted on the distribution of heavy metal content of manganese (Mn) on landfill in Antang Makassar. The study aims to determine the presence of heavy manganese metal (Mn) in the landfill of Antang Makassar waste landfill. There are 4 lines namely line A sampling points (A0, A5 and A10), line B sampling points (B0, B5 and B10), line C sampling points (C0, C5 and C10) and line D sampling points (D0, D5 and D10) with a depth of (0-10, 10-20 and 20-30) cm. Total samples analyzed by heavy metal elements using ICP-OES method were 36 samples. The concentration of heavy metal manganese (Mn) in Antang landfill soil has spread horizontally. The results of the analysis showed the presence of heavy metal content of manganese (Mn) in the soil in the Makassar Antang waste landfill, where the samples with the highest heavy metal content were, line A sampling points (A0, A5 and A10) each depth (0-10, 10-20 , 20-30) cm. Line C sampling point C10 at depths (0-10 and 10-20) cm, i.e. sequentially (1660 and 1710) ppm. Line D sampling points (A0, A5 and A 0), except, at the sampling point D0 at a depth of 20-30 cm which is 1460 ppm is still below the normal limit, which is allowed by the Government of the Republic of Indonesia and the General of Drug and Food Control as a pollutant inside soil. Soil pH varies from 4.82-6 and is acidic. Soil pH significantly affects the solubility and mobility of metals, because most metals dissolve in acidic soils. The level of pollution of heavy metal manganese (Mn) for line A, line C and line D at the sampling points (A0, A5 and A10) at depths (0-10, 10-20 and 20-30) cm are included in the category of heavily polluted because the concentration of heavy metals manganese (Mn) contained in the soil far exceeds a predetermined threshold. So that necessary remediation of appropriate prevention to prevent risks to humans and the environment.

Abstract
Seaweed is one of the leading commodities that has enormous potential supported by sea area of 5.8 million km2 with a total area of seaweed cultivation reaching 1.110.900 ha (LIPI, 2009). South Sulawesi Province became the main center of seaweed in Indonesia with the largest contribution (29%) in 2016, one of which was in the Takalar Regency. One type of kelp cultured in ponds is Glacilaria sp. Seaweed production is a strategic step at the level of crop development as it involves a high workload, a simple growing technology, a relatively short planting time of about 45 days (fast yield) and relatively cheap production costs. The growing demand for seaweed from year to year does not follow rising production volumes and fluctuating prices. The purpose of this research is to determine the description of the agrifood subsystem and to determine the productivity of the seaweed company Glacilaria sp. in the regency of Takalar. The design of the research uses qualitative and quantitative types. The number of samples used was 63 people. The method used is observation, interviews and questionnaires. The results of this research are a general description of the agri-food subsystem of seaweed, namely that the seizure process begins at the stage of land supply, facilities and infrastructure, nurseries and maintenance up to the stage of development. exit from harvesting, drying and selling processes. The results of the formulation of productivity, is the use of production, must be lower than the results obtained in terms of inputs, so that the income of fishermen exploiting seaweed Glacilaria sp. can increasing.

Abstract
Sea Cucumber (Holothuroidea sp) is one of the fisheries commodities that has good prospects to be developed because of its high economic value and potential promising market demand both in the local and international markets. Data from the Ministry of Maritime Affairs and Fisheries throughout 2012-2016 shows the trend of sea cucumber exports has increased from 900-2000 tons/year. As for China, Singapore and Taiwan remain the main customers. Demand for sea cucumbers, especially for exports, has increased every year so that fishing and hunting in the sea take place more intensively causing a decrease in catches from the sea. Sea cucumbers can be processed into food and traded in various forms in the form of: food supplement products, cosmetic products and medicinal products which are efficacious for the treatment of various diseases. In the Province, there are many who are engaged in sea cucumbers by implementing the agribusiness system which is not yet optimal. The influence of internal and external factors and the need for sea cucumber development strategies. This study aims to determine the level of financial feasibility, the influence of internal and external factors, sea cucumber agribusiness development strategies. The study was conducted in South Sulawesi Province with locations in Barrang Lompo, Takalar and Selayar, using survey methods with data collection techniques through direct observation, interviews and observations. Data were then analyzed using financial feasibility analysis, SWOT analysis and QSPM analysis. The results showed that sea cucumber business is feasible to run, internal factors (strengths: high sea cucumber prices, weaknesses: use of fishing gear not in accordance with work safety standards) and external factors (high market potential opportunities, threats limited stock), Sea Cucumber has good prospects going forward with the Cultivation strategy, the application of processing technology, Optimizing business and market potential, Increasing capital cooperation

Abstract
Penelitian ini bertujuan untuk mengetahui apakah good corporate governance mampu memperkuat / memperlemah pengaruh asimetri informasi terhadap manajemen laba. Pengumpulan data menggunakan data sekunder yang diperoleh dari laporan keuangan dengan menggunakan teknik sampling jenu. Populasinya adalah semua perusahaan yang terdaftar di Bursa Efek LQ 45 Indonesia (IDX) yang berjumlah 45 perusahaan, dan semua perusahaan digunakan sebagai sampel. Hasil penelitian ini telah diuji asumsi klasik dan metode analisis data menggunakan teknik regresi linier berganda dan moderating regression analysis (MRA). Hasil penelitian menunjukkan bahwa asimetri informasi berpengaruh positif tidak signifikan terhadap manajemen laba, yang berarti bahwa manajemen laba tidak lagi ditentukan oleh asimetri informasi tetapi ditentukan oleh faktor lain. Sedangkan variabel good corporate governance menunjukkan hasil negatif signifikan. Ini berarti bahwa good corporate governance mampu melemahkan atau menurunkan pengaruh asimetri informasi pada manajemen laba. Jadi dengan menurunnya asimetri informasi dalam perusahaan maka tindakan manajemen laba ikut menurun.

Studi ini bertujuan untuk menguji secara empiris kontribusi nilai-nilai keadilan organisasional dalam meningkatkan kepercayaa pada pimpinan Perguruan Tinggi Swasta Makassar. Populasi penelitian ini adalah Dosen perguruan tinggi swasta klaster 3 di Kota Makassar. Penyebaran kuesioner dilakukan dengan menggunakan stratified proporsional random sampling pada Dosen Dipekerjakan dan Dosen Yayasan, sehingga diperoleh sampel sebanyak 150 Dosen namun terdapat 27 angket yang cacat sehingga penelitian ini hanya menggunakan 123 Dosen. Analisis data menggunakan Teknik variance-based SEM (SEM-Pls) (Kock, 2010) dengan menggunakan software WarpPLS 6.0. Hasil penelitian memberikan bukti bahwa nilai keadilan distributive tidak mampu meningkatkan kepercayaan dosen pada pimpinan, sementara nilai keadilan prosedural dan nilai keadilan interaksional yang tinggi terbukti dapat meningkatkan kepercayaan dosen pada pimpinan perguruan tinggi. Penelitian ini membuktikan bahwa kompetensi bukan menjadi factor penentu dalam meningkatkan kepercayaan dosen pada pimpinan perguruan tinggi

Abstract
Makalah ini mengulas konsep dan dimensi employee silence behavior (perilaku bungkan karyawan) dalam organiasi, melalui telaah terhadap berbagai literatur yang relevan. Telaah pustaka dilakukan untuk mendefinisikan konsep perilaku bungkam karyawan, serta perkembangan konsep tersebut dani mengeksplorasi hubungan antar variabel didalam model kajian yang pernah dilakukan. Makalah ini menyajikan rangkuman atas berbagai model penelitian yang menggambarkan berbagai factor penyebab sekaligus konsekuensi dari adanya perilaku bungkam karyawan dalam organisasi. Penyebab perilaku tersebut dapat berasal dari individu, pimpinan dan organisasi secara keseluruhan. Terdapat tiga jenis perilaku bungkam karyawan dalam organisasi, yaitu Acquiescent Silence, Defensive Silence, dan Pro-social Silence. Perilaku bungkam tersebut dapat berdampak negatif bagi diri karyawan sendiri dan selanjutnya juga bagi organisasi. Oleh karena itu organisasi harus dapat mengelola fenomena perilaku bungkam tersebut melalui berbagai aturan, program dan pendekatan yang dapat meningkatkan kesediaan karyawan untuk aktif dalam memberikan pendapat dan kritik demi kemajuan organisasi. Pada umumnya perilaku ini tidak mendapat perhatian yang cukup dari organisasi karena dipandang sebagai hal yang biasa. Namun berbagai studi yang relevan menunjukkan bahwa employee silence merupakan fenomena yang harus diwaspadai oleh organisasi karena dapat menyebabkan berbagai dampak buruk terhadap kreativitas dan inovasi, serta berbagai variabel lain seperti : Job Satisfaction, Job Attitude, Commitment dan performance.

Abstract
The Dengue Fever is an infectious disease which has always been one of the main health problems in Indonesian society. Dengue Fever is transmitted by Aedes Aegypti mosquito bites. The purposes of this study is to estimate the relative risk of spreading the dengue fever disease in Padang. Estimation is done using the Small Area Estimation method with the Empirical Bayes approach. Small area estimation is useful for estimating parameters in small subpopulations (areas) which have limited number of samples thus acceptable parameter values are hard to be obtained. In this study the construction of the model is based on Poisson-Gamma model and secondary data from Dinas Kesehatan Padang 2017 is used. This study resulted that for each district in Padang, the average relative risk of the spreading of dengue fever is almost the same, which are at medium and low level.

Abstract
Supply Chain Management (SCM) can be seen from the upstream, midstream and downstream supply chains. Efficiency can be increased by business strategies in all three sections. The fashion industry such as garment and textile is a very dynamic industry where fashion trends change rapidly in a short time. How can produce products that can adjust to consumer trends or needs become a strategy in increasing the efficiency of SCM. SCM downstream side needs, namely customers must be analyzed by analyzing customer experience such as social influence and analysis to avoid running out of stock, the two things are analyzed with certain attributes. Consumer needs can be explored based on customer purchase history and the phenomenon of current fashion trends. Online marketing, e-commerce, social media as trading media can provide knowledge. Methods related to data analysis such as big data analysis and social trends continue to develop. In this study, the concept of analytic data will be proposed by applying various factors such as social factors, social influences, business, trade, purchase history, collaborated with various techniques with the aim of knowing the needs of people in the fashion world. What data is relevant will be analyzed and processed by relevant methods with the result tendency community on certain fashion. This research will produce an analytical data model of social influence that focuses on the domain of the fashion world which is the input and recommendation for the downstream part of the Supply Chain Management System in order to increase the efficiency and effectiveness of SCM.

Abstract
The lack of coordination in the integration of information systems between government agencies that issue identity numbers causes replication and redundancy of population information data. Another problem is the emergence of citizens concerns over data integrity and security due to national identification records is also used by the private sector. In this paper, one of the solutions offered to overcome the above problem is to build an integrated national identification database system between government agencies by applying the concept of Single Identity Number (SIN) using blockchain technology. Blockchain is a secure and robust system for keeping a record of the identities of all citizens and also able to facilitate data integration between institutions. This paper uses the strengths of blockchain to possess characteristics of immutability that it is possible to store national identification records. The available attributes of the national identification records can be used effectively in applications such as health care records, passport issuance, banking, etc.

Abstract
Abstract. Silicon Oil, which is commonly used in vitreoretinal surgery, is known as Polydimethylsiloxane (PDMS). Silicone oil is used as a substitute for vitreous humor in vitreoretinal surgery. Silicone oil is needed in Indonesia and must be produced with sufficient quality and quantity for domestic needs, currently vitroretinal surgery still uses silicone oil imported from abroad. In this study, PDMS has been synthesized using an addition polymerization process with a polymerization chain growth mechanism, with the monomer octamethylcyclotetrasiloxane, the initiator of Pottasium Hidroxida and the hexamethyldisiloxane chain terminator. The duration of mixing varied from 20 minutes, 30 minutes and 40 minutes, to study the effect of time on PDMS characteristics. The PDMS synthesis we produce is between 65.30% and 86.71% with various viscosities in the range of 900 m.Pa.s and 5000 m.Pa.s. FTIR spectroscopic measurements were found that all synthesized samples were found to have functional groups and structures similar to commercial silicon oil. UV-Vis and refractometer measurements, all samples have transmittance close to 100% and refractive index between 1.3589 and 1.4059. The effect of the length of time on the PDMS gel is on the viscosity the longer the mixing time the higher the viscosity, this mixing occurs at 170oC, stirred using a magnetic stirrer with 300rpm and the concentration of 1M Pottasium Hydroxide. In this study the propagation stage to form a gel began to form in 20 minutes.

Abstract
Mathematics has an important role in developing the human mind power, one of them is critical thinking. The critical thinking ability might be taught by using problem solving. The strategy that is used to solve the problem can be affected by student-cognitive style. The research purpose is to identify student- critical thinking ability in problem solving based on their cognitive styles. The research subjects are two student who have reflective or impulsive cognitive style. The data were collected by giving cognitive style, mathematics ability, and problem solving tests, and interview. The research result showed that the reflective student has seven indicators of critical thinking ability, they are the ability to comprehend and express the meaning of information, distinguish relevant and irrelevant information, analyze the data, collect and organize information, find ways of completion, draw conclusions, and evaluate the completion. Based on the level of critical thinking, she is very critical. While impulsive student has four of the seven indicators of critical thinking ability, they are the ability to comprehend and express the meaning of information, distinguish relevant and irrelevant information, collect and organize information, and draw conclusions. Based on the level of critical thinking, she is critical enough.
