Agriculture in Indonesia is a vital sector that can fulfill food needs and provide livelihoods. However, agriculture also contributes to greenhouse gas (GHG) emissions. Indonesia's agricultural sector contributes around 14% of emissions globally and 7% nationally. Greenhouse gas emissions such as methane gas CH4, carbon dioxide CO2, and nitrous oxide N2O are generated from agricultural activities ranging from land preparation, fertilization, transportation of agricultural products, to processing in factories. These greenhouse gas emissions influence the climate change that occurs and affect the increase in temperature and rainfall patterns. In mitigation efforts, this study noted several steps taken. Energy conversion, such as the use of biogas from animal manure can reduce CH4 emissions and the use of pellets from palm waste processing can reduce CO2 emissions. Reforestation with special carbon-absorbing plants to reduce CO2 emissions. The use of organic fertilizers as a partial replacement for inorganic fertilizers is useful in reducing CH4 and N2O emissions. Through this systematic review, it is expected to contribute to the understanding of the role of the agricultural sector in greenhouse gas emissions in Indonesia and provide insight into mitigation efforts that can be applied in achieving sustainable agriculture.

Sungai Limau Village is a coastal area that is prone to groundwater pollution. The raw water source used by residents comes from groundwater by digging wells of poor quality. This research aims to determine whether there has been contamination of residents' well water in Sungai Limau Village based on testing Biological Oxygen Demand (BOD) and Total Suspended Solid (TSS) parameters as well as providing information to residents regarding the appropriate location of wells to be used as a source of raw water. The groundwater sampling method refers to SNI 6989.58:2008 and is taken by Grab Sampling. BOD parameter testing is tested ex-situ in the laboratory in accordance with SNI 6989.72:2009. TSS parameters were tested ex-situ in the laboratory in accordance with SNI 06-6989.3-2004. Then the results of the well water quality test are mapped to the distribution of each parameter. Based on the results of the well water quality test, a value was obtained that exceeded the quality standard according to PP No.22 of 2021 Class 1 for raw water, the Biological Oxygen Demand (BOD) parameter with a value of 123,279 mg/L. So the well water of the residents of Sungai Limau Village is not suitable for use as a source of raw water because it has been polluted by organic materials.

Distribution and Location of Joseon Shinto Shrines during the Japanese Colonial Period
Authors:   Institute For Kyeongki Cultural Studies, Choi Jin Seong
Published: January 2024

This article attempts to grasp the distribution and location trends of Joseon Shinto shrines built during the Japanese colonial period. Joseon Shinto shrines are divided into Shinto shrines(神社) and Shinmyeong shrines(神明神祠) according to their hierarchy. 81 Shinto shrines and 865 Shinmyung shrines were identified in the “Joseon Government-General's Gazette” (1915-1945). For them, the period of completion of the official formalization of the Joseon Shinto shrines (1915-1929) and the period of the Hwangminhwa(皇民化) policy (1930-1945) were divided into two periods, and a distribution map was drawn up. This distribution map overlapped with the railway network built during the Japanese colonial period and was used to identify the distribution trend of the Joseon Shinto shrines. As a result, it can be seen that during the period when the Joseon Shinto Shrine was fully publicized, it was very accessible to the railway network. However, during the period of the Hwangminhwa Policy, the Shinmyeong Shrine spread throughout the country, and its connection with the railway network gradually decreased. This is due to the policy of 'One Myeon(面), One Shrineism' implemented in 1936, Shinmyung Shrines were intensively built up to the myeon region regardless of the railway network. This distribution trend is well seen in Jeollanam-do, Hwanghae-do, and Gyeonggi-do, where many Shinmyung shrines have been built.
The tendency of the location of Joseon Shinto shrines was examined by dividing them into Shinto shrines and Shinmyeong shrines. To this end, the types of locations were identified at 37 places where symbols and names representing Shinto shrines were displayed in the “Topographic Map of Joseon”. In addition, among them, the visual location of the Shinto shrine was analyzed by selecting 6 places where the location of the Shinto shrine was confirmed by photographs, as well as 6 places of Shinmyeong Shrine found on the “Topographic Map of Joseon”. In the case of Shinto shrines, due to the characteristics of the city where they were built, they were divided into open port cities, transportation cities, and traditional cities. As a result, all of the 12 Joseon Shinto shrines selected as examples are located on hills or in the middle of gentle slopes, securing excellent views. In addition, they were landmarks that could be seen from anywhere in the city, town and myeon because they faced the central place in city, and they were relatively close to Japanese settlements due to their easy access to railway stations. Because of this location, the hill on which the Shinto Shrine was built was designated as a park, and later most of it became a park. This hilly-oriented location of the Joseon Shinto Shrine can be extended to the location tendency of all Joseon Shinto Shrines built during the Japanese colonial period.
Influence of outer-rise faults on shallow décollement heterogeneity and sediment flux at the Japan trench
Authors: Schottenfels Emily , Regalla Christine , Nakamura Yasuyuki
Published: January 2024

We investigate the impact of outer-rise normal fault subduction on the structural evolution of the décollement and frontal prism in a portion of the Japan trench that hosted the 2011 Tohoku earthquake. We use seismic reflection data to map the relative occurrence of sediment accretion, sediment subduction, and frontal tectonic erosion in the shallow portion of the subduction zone and correlate these deformation styles to the magnitude of outer-rise fault throw and incoming plate sediment thickness. These data reveal spatial heterogeneity in the modes of deformation over distances of 5-10 km that necessitate correlative heterogeneity in the geometry and composition of the shallow décollement over similar length-scales. We find that sediment accretion predominantly occurs in regions where incoming plate sediment thickness is greater than fault throw. In these areas, the décollement appears to be non-planar and compositionally homogenous. Conversely, frontal tectonic erosion and slope failures are predominantly observed in regions where fault throw is greater than sediment thickness. In these areas, the décollement may be planar but compositionally heterogeneous. Additionally, spatial variations in near trench slip appear to correlate with the dominant deformation modes, suggesting that both sediment thickness and outer-rise fault throw may be important controls on shallow megathrust behavior.

Published: January 2024

The Indonesian Sign Language System (SIBI) is used to translate sign language into text or speech. SIBI helps improve communication between people using sign language and those who do not understand it. Unlike commonly used languages, SIBI sign language is less known to most people due to a lack of interest. To address this, an artificial intelligence-based application was developed, focusing on deep learning to recognize SIBI sign language hand movements in real-time. The model was created with 20 epochs, a batch size of 16, and a learning rate of 0.001. It consists of 13 layers, with the ReLU activation function used for the input layer, while the output layer uses Sigmoid. The ADAM optimizer was used to expedite the model creation process. The image dataset used had a size of 300x300 pixels. In the classification testing of the SIBI alphabet results in this study, it was tested using distance tests. The distance between the webcam and the SIBI language speaker was divided into two categories: 40 cm and 60 cm. For a 40-cm distance, an accuracy of 87.50% was obtained, and for a 60-cm distance, an accuracy of 79.17% was achieved. One limitation of this study is that two alphabets, J and Z, were not included in the dataset. This is because recognition of these two alphabets requires not only finger pattern recognition but also recognition of their gesture patterns.

Corrosion is an electrochemical process between the metal surface and a corrosive environment that can lead to significant losses in various industries, especially in the oil and gas sector. Experimental studies are conducted to evaluate the performance of corrosion inhibitors and available resources. In this research, a machine learning (ML) approach is employed to assess the effectiveness of expired drug compounds as corrosion inhibitors. The primary challenge in machine learning is obtaining a highly accurate model to ensure that predictions are relevant to the properties of the tested materials. Therefore, the polynomial function is tested in the gradient-boosting regressor (GBR) algorithm to enhance the accuracy of the developed ML model. The results indicate that the implementation of the polynomial function in the GBR algorithm can improve the accuracy of the prediction model based on R2 and RMSE metrics.

Published: January 2024

Injection molding is a plastic production process by injecting liquid plastic into a mold. One of the injection molding products is an eye drop head. Eye drops in its production experienced rejects reaching 37.5% due to defects. The purpose of this optimization is to obtain the optimum setting of injection pressure and time of injection molding machine using RSM. The method to achieve the goal through finite element approach with pre-processing includes design and setting boundary conditions for injection pressure (10.5, 11, and 11.5 MPa) and injection time (1.9, 2.0, and 2.1 seconds). Post processing displays the results of product mass, defects, and quality prediction which are further optimized using RSM to obtain optimum values. The simulation results show that higher injection pressure and lower injection time have given satisfactory results for all three parameters (product mass, defects, and quality prediction) observed. Based on the optimization results, the optimal injection molding settings were obtained at an injection pressure of 11.5 MPa and injection time of 1.9 seconds which resulted in a product mass of 0.429 g, weld line defect of 0.1384, and quality prediction of 80.9%.

So it can result in degradation, decreased efficiency and construction, poor water quality, and higher maintenance costs. Water channeled through rusty pipes will pollute the water and adversely affect the health of those who consume it. This study aims to determine the factors causing failures of GI pipe in the distribution pipeline that have failed due to corrosion. The tested pipes is 1/2"ᴓ sized, 5-year-old corroded pipe whose distribution uses a gravity system and a pumping system. To support this analysis, operational data on fluid and environmental conditions around the pipeline are needed, observations on macro and micro structures, and hardness testing. The corrosion rate is calculated through the thickness loss method and the corrosion rate in the gravity system is 0.153 mm / year that higher than pipe in pumping system. Microstructure observations support the characterization of the material that this pipe is a mild steel, where this type of steel has a high Fe content so it is vulnerable to corrosion attacks. Rockwell hardness testing showed that the corrosion rate is directly proportional to the hardness value of the pipeline. The results of the analysis show that the environment around the pipe which has low soil resistivity and high humidity levels is the main factor in the occurrence of uniform corrosion of the pipe. The selection of inappropriate materials is also supportive as the cause of corrosion occurring.

Electrical energy is one of the basic needs that is very important in life, in addition to the physiological development of living things, electricity is also an input for various efforts or activities in order to produce something for survival. Therefore, renewable energy that is more environmentally friendly and an inexhaustible source of energy is needed, namely wind energy. This power generator is called a wind turbine with a vertical shaft. This turbine converts wind energy into mechanical and electrical. In order to obtain a turbine design with high efficiency.  It is also necessary to balance and align each component frame attached to the turbine rotor to produce a perfect/ideal rotation, so as to minimize the occurrence of vibrations caused by the imbalance. the results of calculations with the analytical method on Darrius Helix type obtained value = 0.125 Newton, and = 0.175 Newton, and the value of the angle = 63.43490. Alignment testing is carried out to determine the value of the misalignment between one blade with another blade. The results of the balancing test with the blade ballast obtained additional value, the blade D was 70 grams and the results from the plate addition test were obtained according to the calculation of the analytical method but also less than the maximum requiring additional load on the blade body to get blade A = 12 grams, blade B = 0, blade C = 40 grams, and a spoon D = 90 grams. For the results and discussion of the balancing and alignment method on the savonius type using the static balancing and alignment method using a dial indicator, the values obtained are in the fields A and B, the addition of mass is 59,007 grams and 59.007 grams with angles A and B 11.88 ° , and the value The misalignment deviation in the A, B and center planes is A: 4mm, B: 0.04mm, middle: 0.52mm, while the shaft alignment value is 0 because the value of the alignment of the shafts is the same or parallel.

The article proposes a methodology for testing a library of cryptographic transformations with the implementation of an improved encryption scheme on generalized Suzuki 2-groups in the MST3 cryptosystem. The need to improve existing methods of cryptosystem creation is driven by progress in quantum computer development, which possess sufficient computational power to compromise many existing public key cryptosystems. This is especially true for systems based on factorization and discrete logarithm, such as RSA and ECC. Over the last nearly 20 years, there have been proposals for using non-commutative groups to develop quantum-resistant cryptosystems. The unsolved word problem, formulated by Wagner and Magyarik, uses permutation groups and is a promising direction in cryptosystem development. Magliveras proposed logarithmic signatures, a special type of factorization applied to finite groups, and the latest version of this technology is known as MST3, based on the Suzuki group. The first implementation of the cryptosystem on the generalized Suzuki 2-group had limitations in encryption and protection against brute force attacks. Over the past years, many proposals have been made to improve the basic design. The research conducted by the authors expanded the possibilities of using public cryptography by refining parameters based on non-Abelian groups. The article demonstrates the methodology for conducting tests of the practical implementation of the library of cryptographic transformations with the implementation of an improved encryption scheme on Suzuki 2-groups, confirming its functionality.

Information protection during message transmission is one of the most important tasks in the modern world. The workstations of a particular organization can be well protected using different software and hardware means, but when information is transferred to an open unprotected space, there is a high probability of data leakage, interception, and substitution. In most cases, the use of insufficiently effective security measures causes the loss of personal data of citizens, data of an enterprise or organization that is a commercial secret, information with limited access or even state secrets of the critical infrastructure sector. In this case, it is considered appropriate to use modern cryptographic methods to organize secure data transmission. Considering the ever-growing statistics of cyberattacks on information and telecommunication networks, after in-depth analysis and development of this issue, the authors of the article highlighted the current directions of protection of information and telecommunication networks and security solutions in information and telecommunication networks. The authors have comprehensively covered and investigated the basic principles of the modern state of data transmission security and the organization of information protection during its transmission using the TLS protocol, which made it possible to determine the directions for solving or modernizing existing information security means. Also, attention is paid to the development of a software implementation of the module for secure data transmission in the information and telecommunications network using the improved TLS protocol by means of OpenSSL, which made it possible to establish connections using digital signature algorithms. The authors are planning a series of scientific and technical solutions for the development and implementation of effective cryptographic methods to ensure the security of information and telecommunications networks
