Published: June 2023

Sustainable finance is a form of financing provided by Financial Institutions (FIs) to debtors by considering sustainability aspects into their decisions. Sustainable finance has not become a serious concern and orientation of FIs in providing credit or financing to debtors. Problem financing reflects the problem of two conflicting economic actors (agency). By conducting an analysis of sustainable financial performance and agency relationship analysis, this study shows that assessing the sustainability performance of a company (the debtor) required detail criteria and indicators of sustainable finance. When disbursing credit, banks cannot only look at the financial health and stability of a company. This is because companies that already have sustainability certification and fulfill administrative aspects still have unresolved Environmental, Social and Governance (ESG) issues. The involvement of the parties in building an “Information Hub” (coordination forum) related to ESG practices centered in the regions is important.

Published: June 2023

Research has been conducted into the nature of geothermal rocks in Pamekasan. This place is located in Tlanakan Pamekasan. This study aims to determine the composition of mineral compounds in the soil so that fire can burst out from the soil and the soil does not melt. Three steps can be done with simple refinement and filtering methods, namely X-Ray Fluorescence (XRF), X-ray diffraction (XRD), and Scanning Electron Microscope (SEM). The results of XRF analysis show the element of Api Alam 1 is Ca 66.2%, Api Alam 2 is Si 37.4%, and in hot springs, is Si 39.6%. The XRD results show that mineral qualitatively in Api Alam 1 was in the form of CaCO3 compound at 60.1% and SiO2 at 39.9%, while in Api Alam 2, hot water sources were in the form of SiO2 compound (>90%). SEM Results on Api Alam 1 show that the sample is almost homogeneous (the distribution of CaCO3 and SiO2 is uneven), the presence of slab-shaped clumps that identify the presence of varying grain size, and with high porosity, which indicates that the sample is partially amorphous in structure, in Api Alam 2. The Hot springs show irregular aggregations and poor homogeneity of the sample. The size of the three samples is ten μm or 10.000 nm, while PSA results showed an average size of Api Alam 1 was 509.7 nm, Api Alam 2 was 891.3 nm, and Hot Springs was 468.3 nm.

Published: June 2023

In utilizing various alternative energy, generators are used to convert alternative energy into electrical energy, for example, biomass, wind, and hydroelectricity. Generally, the measurements made on the generators are rotational speed measurements in the form of revolutions per minute (RPM). In developing lab-scale alternative power sources, the availability of generators with complete quality and specifications is still minimal, including RPM capacity. Therefore, the measurement which can read the RPM accurately, digitally, and automatically is needed. However, the measurement tools available are still manual, not automatic, and prone to parallax errors. Hence, a digital and automatic RPM measurement was developed in this study. Two different sensors were used to develop digital RPM based on a microcontroller. The stages obtained started with electronic system development, calibration, and testing of lab-scale renewable energy systems. The measurement can be read from the infrared and optocoupler sensors on the Archimedes turbine. The measurement results showed that the use of the Optocoupler sensor is more accurate than the infrared sensor. This is based on the data obtained from calibration and testing results on the Archimedes turbine. This RPM measurement is digital and real-time.

This study aims to cluster and visualize the earthquake data on a geographical map to determine earthquakes' characteristics using the k-means algorithm. Cluster analysis using the k-means algorithm was carried out on the earthquake data. K-means algorithm is familiar and is one of the well-known techniques to have been applied in cluster analysis. One of Its advantages in cluster analysis is scaling large datasets, for example, earthquake data. The data used in this study is earthquake data in the West Nusa Tenggara from 1991 to 2021. Applying the proposed k-means algorithm, the optimal number of clusters (k) used in this clustering is 2, based on the highest silhouette score of 0.749. The cluster analysis on the geographical map showed that the epicenters of the earthquakes were pretty spread out before 2018, and the number of earthquakes in the eastern region of West Nusa Tenggara is more than in the western area. However, in 2018, the clusters were all bunched in the northern Lombok region. There were a few earthquakes in the west region in 2018, but they happened before August 5. Even after 2019, most earthquakes continue to occur, with the epicenters clustered close to the northern Lombok region

Published: June 2023

The use of pineapple peel has not been paid attention to because of the lack of public knowledge regarding the content and benefits of pineapple skin. However, it can use pineapple skin for herbal drinks and animal feed. Pineapple peel has phytochemical compounds and bioactive compounds such as ZnO. Therefore, this study was conducted to determine ZnO's crystalline phase and the functional group from pineapple peel extract. Synthesis of ZnO from pineapple peel extract used the green synthesis method, with the following steps: pineapple peel was pounded and stirred by heating at 80°C, and then ultrasonicated. The solution was added with NaOH and centrifuged at 4000 rpm. This result is heated at a temperature of 120°C with a 6 and 12 hours holding time. After that, it cooled to room temperature. The results of XRD analysis obtained the optimal ZnO crystalline phase at a holding time of 12 hours according to the pdf cards database (96-210-7060) and nanocrystalline size of 17.55 nm. The FTIR results on the ZnO sample had an absorption peak of 4000-400cm-1 with functional groups O-H alcohol and phenol, -C=C alkene, C=O, C-O, C-N, and Zn-O. It is hoped to be applied later in the medical and industrial fields by obtaining ZnO samples from pineapple peel extract

Published: June 2023

Wind shear is a condition that is detrimental to aircraft because it can cause the aircraft to experience lift, especially during take-off or landing, where wind shear can occur due to bad and unstable weather, so research on the correlation of the atmospheric lability index to wind shear is very important to prevent a plane crash. This research aims to determine the magnitude of the correlation of the atmospheric lability index to the vertical wind shear that occurs at I Gusti Ngurah Rai Airport, Bali. In this research, the Wind Profiler Radar (WPR) brand scintec LAP-3000 was used to obtain wind shear data in the form of wind direction and wind speed data then radiosonde to obtain atmospheric lability index data in the form of Lifted Index (LI), Total-Totals Index (TT), K-Index (KI), and Convective Available Potential Energy (CAPE) index values for each month in 2019-2020. Wind shear measurement was carried out at an altitude of 100-3000 m and data were taken on the difference in wind direction ≥ 60o and the difference in wind speed ≥ 10 knots. Meanwhile, measurement of the atmospheric lability index is carried out by a flying air balloon that has been equipped with a transmitter. All LI, TT, KI, and CAPE index value data and the number of wind shear events were analyzed with Pearson Product Moment correlation. The value of the correlation coefficient (r) between the LI, TT, KI, and CAPE indices was obtained for successive wind shear events of -0.786; 0,250; 0.738, and 0.713. These results show that the LI, KI, and CAPE index values can be used as a reference to predict wind shear events because they have a strong correlation, obtaining a correlation value between 0.60 to 0.79 compared to the TT index.

Published: June 2023

First-principles calculations are increasingly crucial in searching for new materials with customized properties or new functionality. First-principles calculations are superior in speed and cost, and comparable to experiments in terms of accuracy. Two-dimensional (2D) ferromagnetism materials were successfully fabricated experimentally in atomic thin films of CrI3. 2D intrinsic ferromagnetism with perpendicular magnetic anisotropy energy (PMAE) is an encouraging applicant compatible with high-density magnetic storage applications. In this study, spin density functional calculations are investigated on the magnetic anisotropy energy (MAE) in 2D monolayer ferromagnetic CrI3 using a first-principles electronic structure calculation. We include the MAE part calculation from the magnetocrystalline anisotropy energy (MCAE) that comes from the spin-orbit coupling (SOC). In the present calculation, the MCAE part, in addition to a usual scheme of total energy (TE), was evaluated using a grand-canonical force theorem (GCFT) scheme. The MCAE of 2D monolayer ferromagnetic CrI3 is 1.7 meV/unit cell and verified it has an easy-axis perpendicular to the crystal plane, which is a good agreement with experimental measurement. In the latter scheme, employing GCFT, we evaluated atom-resolved, k-resolved, and atomic k-resolved analyses for MCAE can be performed. From the GCFT result, the Cr atom indicates that it is the primary origin of PMAE in the atom-resolved MCAE. The negative MCAE contribution is in points, and the positive MCAE is mainly placed at the line in the 2D first Brillouin zone. Our systematic calculation in this work may also help design an effective structure of monolayer CrI3 in new 2D material magnetic sensor and spintronic device designs.

DETERMINATION OF RUPTURE DIRECTIVITY USING THE LEVENBERG-MARQUARDT ALGORITHM: A CASE STUDY PHILIPPINE EARTHQUAKE (15 DECEMBER 2019 M_w 6.8)
Authors: Fahmi Muhammad Nurul , Sungkono Sungkono , Madlazim Madlazim
Published: June 2023

Earthquake source mechanisms are used to determine local geological characteristics and hazard mitigation. There are several approaches to determine the mechanism of earthquake. In this paper, the relative time of the rupture duration is applied to determine rupture directivity. In determining rupture directivity, the Levenberg-Marquardt (LM) method is proposed to solve the inversion problem. To test the reliability of this method, teleseismic data with an epicentral distance of 40o from the Philippine earthquake on 15 December 2019  6.8, which had a good seismic station distribution with a total of 35 stations, is used. Telesismic data from each station is filtered in the range of 0.25 to 1 Hz to obtain an accurate rupture duration. Furthermore, the rupture duration data set was inverted using the LM method to obtain the direction of earthquake rupture. The results obtained by the curve fitting using the LM method had a good agreement between the observed data and the calculated data. From the curve fitting results, the rupture propagated in the NW direction with azimuth 320.60o ± 2.30o, and this had the same results from previous studies. Therefore, from rupture directivity, the actual fault plane of this earthquake was NP1 which had a strike/dip/rake value of 321o/75o/13o, respectively. The results indicate that the Philippines earthquake of 15 December 2019 had the SE-NW fault orientation, which is part of the Cotabato fault system. The implication of this research is for a preliminary study related to the characteristics of earthquake rupture in areas that have a high level of seismicity. Thus, local residents can avoid areas where ruptures propagate when carrying out earthquake mitigation.

Published: June 2023

Many building materials that function as insulators to maintain indoor temperature stability during hot weather have been developed. One of them is porous ceramics applied to building walls as heat absorbers. Research related to the manufacture of porous ceramics began to emerge to find the optimal composition when applied as an insulator that can absorb heat well. In general, porous ceramics use activated carbon as a pore agent. Activated carbon can be obtained by carbonating agricultural wastes such as coconut shells, hazelnut shells, rubber fruit shells, rice husks, and cocoa shells. Research continues to develop in finding the best-activated carbon base material according to the required material characteristics. Researchers will take advantage of the abundant potential of local natural resources. The method used to make porous ceramics is to mix clay and activated carbon with a clay-carbon composition ratio of 100:0, 90:10, 80:20, 70:30, 60:40, and 50:50. The sample is made by mixing the two materials and then printed by dry pressing method with a load of 5 tons held for 10 minutes. After the sample is dried at room temperature, it is sintered at 900oC with a holding time of 3 hours. Next, the sample is characterized by determining density, porosity, and water absorption and then tested for thermal properties. After that, the surface morphology and elements in the sample are seen. The optimum composition of clay-carbon mixture is 70:30 grams.  Ceramics using activated carbon from rubber fruit shells are suitable as building construction materials as heat insulators because they can absorb heat up to 500oC.

Published: June 2023

The rail cant is an important geometry parameter and is commonly monitored to ensure railway safety and comfort conditions. Understanding the influence of cant variation on the performance of railway components is extremely important to define the tolerance limits of the track and adequacy of maintenance plans. There are numerous rail cant patterns on railways, 1:40, 1:30, 1:20. However, the optimal rail cant to reduce the stress and wear of rail head not been extensively studied. This work performs an analysis of the effect of the rail cant on the rail head stress distribution. To investigate stress and strain in rail head, a Finite Element Model with Ansys software was used. For the analysis was considered a 136RE rail, axle load of 32 ton and AAR-1B wheel profile. The rail cant was varied in 0, 1:20 and 1:40. The results show that the stress in rail and wheel increases with the rail cant. The maximum stress occurred in the condition with rail cant of 1:20. The variation of cant from 0 to 1:20 results in a decrease of approximately 9% in maximum stress, ranging from 947 MPa to 867 MPa. The wheel/rail contact in cant zero condition occurred close to the transition of the wheel tread and the beginning of flange root, resulting in a dynamic instability in the wheelset. In addition to higher contact stress, increases the propensity for the hutting phenomenon, which can accelerate rail and wheel wear

Authors: Kau Sofyan A. P. , Suleman Zulkarnain , Irwan
Published: June 2023

This paper discusses traditional Islamic criticism of the concept of heresy in Salafi Islam, categorizing every new act in religion as iconoclastic heresy. Based on this concept of heresy, ritual ceremonies and practices of traditional Islamic religious traditions are classified as acts of heresy. Through literature research based on literary document sources using abstractive inductive logic methods and content analysis, this study found that ritual ceremonies and practices of traditional Islamic religious traditions are not acts of heresy because they are based on theorem (al-Quran, hadith and allegiance) it is new. New actions (mutants) are categorized as bid'ah if they conflict with the Quran, hadith, and a tsar. Traditional Islam criticizes the concept of heresy in Salafi-Wahhabi Islam for being ahistorical because several traditions show that the innovation of a friend, tâbi'u tâbi'uttab'în, while this innovation was not ordered and practiced by the Prophet; instead, was carried out by the generation of the Salaf.

Published: June 2023

This study aims to explore the management of da'wah organizations generally relies on an unlimited donation mechanism. The non-profit pattern makes it possible for organizations to experience financial risk in times of crisis. This paper reveals the efforts made by the Rumah Tahfiz Impian (RTI) in Bengkulu City to continue to be sustainable during Covid-19. Field data was collected through in-depth interviews with ten informants; non-participant observations were made several times to obtain additional evidence and documentation that was considered supportive. All data is tabulated and analyzed using coding, categorization, and thematic systems. Our panel found that cost-sharing was the key to RTI's success in getting out of the crisis. Inconsistencies in donor donations are still resolved by dividing the daily operational burden among the students' parents and the community around the environment. Several efforts were made, such as scheduling pickets between side dishes and vegetables, rice or primary food donations, and money. This finding provides insight into Rumah Tahfiz which has cases of opening institutions that need more planning and management skills. Research with the same focus but for different cultural backgrounds of society needs to be carried out in the future
Fatwas of the Indonesian Ulama Council (MUI) on National Strategic Issues 2006-2018 in the Perspective of Maqashid al-Syariah
Authors: Matsum Hasan
Published: June 2023

This study discusses the Fatwa issued by the Indonesian Ulema Council on National Strategic Issues 2006-2018. The discussion is important because MUI's authority in issuing fatwas is still directly proportional to the diversity of the Muslim community in Indonesia. Knowing the MUI's considerations in issuing a fatwa will certainly influence the appreciation of implementing the fatwa. However, studies on MUI fatwas are still limited to the study of faith and worship, although nationality is also a priority for MUI in giving fatwas. In constructing the results of the study, the authors use the normative law method, so the legal source obtained becomes the secondary data. The results of the study concluded that MUI's consideration in issuing fatwa on National Strategic Issues is hifz al-ummah. Hifz al-ummah is an aspect of al-daruriyah in maqashid al-shariah, namely maintaining the principles of "togetherness" or "national integrity" as a nation, and seeking the benefit of being present in that life.
Issuance of Family Cards: An Overview of Maslahah Against Legitimacy of Marital Status for Sirri Married Couples
Authors: Fauzan  , Rohmadi
Published: June 2023

This study aims to comprehensively describe the issuance of Family Cards in the perspective of maslahah (social benefit) and justice for the legitimacy of marriage for sirri married couples in Bengkulu Province. This research is a qualitative empirical research with a statutory approach, a case and field approach, and a concept approach. This study found that the issuance of Family Cards for marriages of unmarried couples is a form of upholding justice in a social (commutative) framework where everyone has the same rights over marital status. On the other hand, the issuance of a Family Card for unmarried couples can be categorized as maslahah al-khassah (special benefit) which benefits only a few parties, not maslahah al-ammah (general benefit) which applies to the whole community. This study also found that the impact of including the statement "Unregistered Marriage" in the issuance of Family Cards for unregistered married couples can lead to maslahah al-mulghah in the form of legal confusion regarding the legality of one's marriage while at the same time hindering the updating of centralized data which is on the government's agenda.
