Published: November 2022

AbstractThe use of paper directly proportional to the growth in the number of people. The impact is in the form of environmental problems where there is logging of forest trees, and deforestation so that it affects the ecosystem and the natural environment. Trees are cut down and made into paper for human needs, including to make books as learning media. In the current technological era, the use of books as a medium of learning has an impact on students’ declining motivation to learn. To solve the problem, we proposes the application of Augmented Reality (AR) as a learning medium. This research uses Game Engine Unity and Vuforia which can display 3-dimensional objects, and uses Android as the basis of the system. In this paper, we introduce four equipments of athletic sports. The aim of this research is to reduce the use of paper as a learning medium and increase learning motivation. The result of the research is an Augmented Reality-based athletics introduction application that has been tested for its performance using blackbox testing using various conditions of its marker.

Published: November 2022

Abstract
The presence of primary tin ore on Belitung Island can be found in several areas with varying amounts of presence. One area that has the potential is the Batubesi TB area, Burung Mandi Village, Damar District at East Belitung Regency. This research aims to identify mineral assemblages and alteration types in oxide skarn deposits. The methods used are outcrop observation, sampling, and mineralization-alteration identification. Testing of rock samples through petrographic analysis is to identify minerals through their polarization optical properties and GCA analysis (Grain Counting Analysis) is to determine specific types of minerals that cannot be seen through petrographic analysis. Macroscopically, oxide skarn deposits have a greenish-brick red, black appearance which is dominated by ore minerals (iron oxide, iron carbonate, and iron sulfide), and in some parts chlorite mineral dissemination. Based on the observation result of the optical properties of the rock samples, metallic minerals other than those that have been directly identified were found, such as ilmenite, siderite, cassiterite, and chlorite. The results of the GCA analysis indicate the presence of cassiterite, pyrite, quartz, siderite, hematite, and limonite minerals. Based on these minerals, it can be seen that the type of alteration in the study area is skarn alteration.

Abstract
Besides tin mining, oil palm plantations are also being carried out. On the other hand, this region is well known as a producer of good quality white pepper which in 2010 its reputation was legally registered as a geographical indication. This protection is given due to the environmental factor in this region which cause the quality of white pepper in this region is different from pepper in other region. However, the massive opening of oil palm plantations causes Pepper plantation area in Bangka and Belitung continues to decrease. This study uses empirical juridical methods; linking the effect of tin mining and oil palm plantations with the reputation of white pepper as a geographical indication. It uses primary and secondary data in which the primary is obtained from the results of interviews while the secondary data is obtained from literature study data on a number of documents. From the results of the conducted study, it was found that the oil palm plantations which reduce the area of pepper plantations and also change the quality make impact to the reputation. The impact can eliminate the reputation of white pepper as a juridical geographical indication and at the same time automatically end the legal protection of white pepper as a geographical indication.

Published: November 2022

Abstract
Berok River is one of the small scales of fishing activities in Central Bangka Regency for mooring boats and loading-unloading activities. The flow of entry and exit for fishing boats at the mouth of the Berok River often experience problems, where the channel becomes shallow due to sedimentation. The behaviour of sediment transport in river mouths is influenced by hydro-oceanographic conditions such as river discharge, current velocity, tides, and geographical conditions. This study aims to determine the characteristics of sediment transport around the Berok River estuary through 2-dimensional numerical modeling. The modeling is conducted using MIKE21 software for the existing conditions and the condition with groynes structure. Two modules are used in MIKE21, namely the Flow Model Flexible Mesh (FM) and the Mud Transport (MT) module. The data used in the sediment transport modeling include tides, bathymetry, wind, and sediment properties. The simulation results show the average sedimentation that occurs around the Berok River estuary is about 0.6 m/year, and the average erosion is about -0.3 m/year. With the groynes structure on the left and right of the river mouth, the average sedimentation rate that occurs is reduced to 0.39 m/year and the average erosion is -0.1 m/year.

Authors: Suhdi  , Rodiawan  , Wang S C 
Published: November 2022

Abstract
The rubber fruit shell (RFS) activated carbon has been made using KOH as a chemical activating agent with several variations of the impregnation ratio (1:3, 1:4, and 1:5). To ascertain the impact of the impregnation ratio on the attributes of the produced activated carbon, analysis was carried out using thermogravimetric analysis (TGA), Brunauer–Emmett–Teller (BET) method, X-ray diffraction, and a field emission scanning electron microscope. In the impregnation ratio, 1:5 was carried out as the best result; the value for BET surface area and nitrogen adsorption isotherms were 160 m2/g and 62 cm3/g, where the average pore size diameter was 4.6 nm. Besides, this activated carbon also has around 78.40% carbon. According to the findings of this investigation, the impregnation ratio affects the performance of using KOH as an activator to produce activated carbon from rubber fruit shells. In addition, it could be indicated that the RFS has the potential to be an alternative source of relatively inexpensive activated carbon because the raw materials are available in large quantities.

Abstract
Granular Activated carbon (AC) is commonly used for cleaning water contaminated with Benzene and toluene (BT). Regeneration is needed to extend the lifetime of GAC. This study examines the effect of H2O2 concentration as an electron acceptor for GAC bioregeneration by the consortium of Pseudomonas aeruginosa, Pseudomonas fluorescens, Aeromonas hydrophila, Bacillus coagulants, and Bacillus substilis in a fixed-bed bioreactor. Enrichment was carried out for adaptation to benzene and toluene. The enriched consortium was injected into a bioreactor column containing GAC saturated with benzene and toluene. The H2O2 concentration was varied 10 mg/l, 30 mg/l, 40 mg/l, and 50 mg/l. The contaminant mixture was continuously added with Lockhead and Chase (LC) and H2O2 at a flow rate of 18.2 ml/minute and 1 ml/minute, respectively. The outlet sample was analyzed using a Gas Chromatograph-Flame Ionization Detector (GC FID). The consortium regenerated the GAC by biodegradation of adsorbed benzene toluene. Initial inoculation of enrichment was 3.5 x 105 CFU/ml. The final stationary phase was at 120 hours with 1.37 x 1011 CFU/ml. The optimum biodegradation process was at a concentration of 30 mg/l H2O2 with a concentration of benzene and toluene outlet column II of 25 ppm and 40.5 ppm, respectively.

Abstract
The tofu industry during the processing produces waste in both in liquid and solid forms. Solid waste is usually used as animal feed, fertilizer, tempe or crackers. Liquid waste is used as nata de soya, paper, bioplastics, biogas, electrical energy and organic fertilizers. Small-scale tofu industry rarely utilizes tofu liquid waste and some do not carry out processing. Tofu waste contains organic substances and high suspended solids that can pollute the environment. Therefore, there is a need for waste treatment using an aerobic biofilter. The operating Hydraulic retention time was 5, 10 and 15 hours, the filter height was 135 cm and the nipah fiber height was 50 cm. The results of the biofilm attached to the biofilter reactor and palm fiber were successfully formed a brownish red biofilm which is a colony of microorganisms. The optimum time of tofu liquid waste showed a residence time of 15 hours, so that tofu liquid waste meets the quality standards based on the Regulation of the Minister of the Environment of the Republic of Indonesian No.5 of 2014. The effectiveness of the biofilter reactor in reducing COD is 94.24%, BOD is 95.14% and TSS is 68%.
