GANGGUAN DISMORFIK TUBUH PADA REMAJA PEREMPUAN
Authors: Awalya Keisya Putri , Taftazani Budi Muhammad
Published: February 2025

Remaja perempuan, terutama di masa pubertas, rentan terhadap kecemasan terkait penampilannya karena tekanan sosial dan standar kecantikan yang tidak realistis yang diperkuat oleh media. Penelitian ini menggunakan pendekatan literatur untuk mengumpulkan data terkait gangguan dismorfik tubuh, termasuk faktor risiko, pendekatan terapi yang telah berhasil, dan upaya pencegahan yang diusulkan. Gejala dismorfik tubuh mencakup tindakan verifikasi fisik berulang dan menghindari interaksi sosial. Gangguan ini dapat menyebabkan depresi, kecemasan, dan rendahnya harga diri, mengganggu perkembangan, sehingga secara keseluruhan dapat menurunkan kualitas hidup. Hasil penelitian menunjukkan bahwa gangguan dismorfik tubuh pada remaja perempuan dipengaruhi oleh beberapa faktor, termasuk perubahan fisik signifikan selama remaja. Mereka juga rentan berperilaku destruktif, seperti menggunakan obat-obatan atau alkohol, sebagai cara mengatasi stres dan ketidakpuasan. Gangguan ini dapat ditangani dengan terapi non-farmakologis, terutama Cognitive-Behavioral Therapy (CBT). Terapi ini dapat dilengkapi dengan terapi farmakologis untuk mengurangi gejala gangguan dan mencegah komplikasi. Penyuluhan dan pendidikan tentang citra tubuh yang realistis serta kesehatan mental diperlukan di sekolah, termasuk melalui kampanye di media sosial. Kelompok dukungan sebaya, orang tua, dan pengajar dapat menjadi sumber dukungan penting dalam mencegah dan mengatasi gangguan ini.   Adolescent girls, especially during puberty, are vulnerable to anxiety related to their appearance due to social pressure and unrealistic beauty standards reinforced by the media. This study employs a literature review approach to gather data related to body dysmorphic disorder, including risk factors, successful therapeutic approaches, and proposed prevention efforts. Symptoms of body dysmorphic disorder include repetitive physical verification actions and avoidance of social interactions. This disorder can lead to depression, anxiety, and low self-esteem, impeding development and overall reducing the quality of life. The study's findings indicate that body dysmorphic disorder in adolescent girls is influenced by several factors, including significant physical changes during adolescence. They are also prone to destructive behaviors, such as using drugs or alcohol, as a way to cope with stress and dissatisfaction. This disorder can be treated with non-pharmacological therapy, particularly Cognitive-Behavioral Therapy (CBT). This therapy can be supplemented with pharmacological treatment to reduce BDD symptoms and prevent complications. Counseling and education about realistic body image and mental health are needed in schools, including through social media campaigns. Peer support groups, parents, and educators can be important sources of support in preventing and addressing this disorder.

Published: February 2025

This article examines the relationship between two variables: socioeconomic level and media literacy (variable X) and parental participation in stunting prevention (variable Y) in Indonesia. Socioeconomic level has long been considered the most dominant factor influencing the risk of stunting in children. This study introduces an additional variable, media literacy, hypothesizing that it may also impact parental participation in preventing stunting in children. The study employs a quantitative explanatory method using Kendall's rank correlation test. The population consists of parents with children under five years old. Sampling was conducted in two stages. First, the sample size was calculated based on the total population across eight Pre- and Postnatal Healthcare Information Centres (Posyandu) with a 5% margin of error. Second, the sample size obtained was distributed proportionally among each Posyandu using simple random sampling. The results show no significant relationship between socioeconomic level and parental participation in stunting prevention, with a significance level of 0.25. However, a relationship was found between media literacy and parental participation in stunting prevention, with a significance level of 0.023 and a very weak correlation coefficient of 0.109 (or 11%). This suggests that higher media literacy among parents has the potential to increase their participation in stunting prevention, albeit the relationship is very weak. This may be because parents do not directly use social media to obtain stunting information but rather for other purposes, such as entertainment or accessing nutritious recipes for children. Additionally, parents may receive stunting information from other sources, including stunting education provided by Posyandu cadres, village midwives, doctors, and nutrition consultants from local health centres.

Published: February 2025

Countries with a vast sea area have faced great concern regarding maritime security. Indonesia, a maritime country with an enormous marine resource that contributes 2.58% to the country’s GDP, ranked second as a vulnerable country to marine threats, such as Illegal, Unreported, and Unregulated (IUU) fishing. This research analyzes the implementation of Indonesia’s 2021 – 2025 Maritime Policy Action Plan and how the policy network cooperates to eradicate IUU fishing. Through qualitative content analysis, several regulations and laws in line with the policy action plan were subject to the analysis and reports published by authorized governmental agencies, such as the Indonesian Maritime Security Agency and the Ministry of Marine Affairs and Fishery. Based on policy network analysis of reports by ministries and institutions/agencies, sectoral ego and integration are the critical issues to curb in the policy community. The lack of an integrated system of information sharing has been a part of challenges in collaborative efforts to attain the state of a secure and safe sea. In this regard, the government must strengthen the information-sharing system in their policy network and the policy community itself to maximize efforts on the security of jurisdiction territory to eradicate IUU fishing. Negara dengan wilayah laut yang luas sering kali menghadapi permasalahan terkait keamanan maritim. Indonesia, negara maritim dengan limpahan sumber daya laut yang menyumbang 2,58% terhadap PDB negara, mendapatkan predikat sebagai negara terentan peringkat kedua terhadap ancaman kelautan, seperti Illegal, Unreported, and Unregulated (IUU) fishing. Penelitian ini menganalisis implementasi dari Rencana Aksi Kebijakan Kelautan Indonesia 2021 – 2025 dan melihat bagaimana jejaring kebijakan bekerja untuk ‘memerangi’ IUU fishing. Melalui konten analisis kualitatif, beberapa regulasi dan undang-undang yang sejalan dengan rencana aski kebijakan dan laporan-laporan yang dipulikasikan oleh instansi pemerintah yang berwenang, seperti Badan Keamanan Laut dan Kementerian Kelautan dan Perikanan, juga digunakan untuk dianalisis. Berdasarkan analisis pada jejaring kebijakan dalam laporan-laporan yang dipublikasikan kementerian dan institusi/lembaga, ego sektoral dan integrasi memiliki peran yang penting dalam pencapaian rencana aksi kebijakan. Kurangnya sistem pembagian informasi yang terintegrasi menjadi bagian dari halangan dalam bekerja sama untuk mencapai keadaan laut yang aman. Berkaitan dengan hal tersebut, pemerintah harus meningkatkan sistem berbagi informasi dalam jejaring kebijakan dan policy community-nya sendiri untuk mengoptimalkan upaya dalam pengamanan wilayah yurisdiksi dalam rangka pemberantasan IUU fishing.

Published: February 2025

This study aims to explore the strategies used by socioeconomically vulnerable women who are heads of low-income families to meet their family's needs. The research was conducted with four socioeconomically vulnerable women who are heads of low-income families in Pasanggrahan Village, Garut. The research data were collected through semi-structured interviews and observations from June-July 2023. The results showed that the participants used the same strategy template to fulfill the needs of their low-income families. Fulfilling economic needs is done by selling snacks in the market. Then, they save food to meet their daily needs and set aside a little money to fulfill other needs. They borrow from mobile banks when facing emergencies to fulfill daily expenses and trading capital and pay health costs when experiencing illnesses that must be treated. This strategy is carried out because the income generated by poor women's family heads or family members can only partially fulfill the family's basic needs. The poverty experienced by the participants was inherited from their families. However, this can be overcome by providing training to improve community entrepreneurship skills and competencies through utilizing village funds.

SOCIO-CULTURAL TABOOS AND THE RISE OF DIGITAL MEDIA UTILIZATION AS A SOURCE OF INFORMATION ON SEXUALITY BY UNIVERSITY STUDENTS
Authors: Qalbi Salikha Tsamratul , Herawati Erna
Published: February 2025

Drawing on John Macionis' definition of sexuality, this study explores the increasing use of digital media as the primary source of information on sexuality among university students, driven by socio-cultural taboos surrounding discussions of sexuality and the declining role of parents in providing education and guidance on sexual matters.  It examines the impact of these socio-cultural factors and their implications for students' understanding of healthy and responsible sexuality. It also aims to provide insights for stakeholders in developing more effective and open approaches to sexual education within both family and educational institutions. This study was conducted using a mixed-method approach combining quantitative and qualitative data, involving university students in Bandung City. The result of this study suggests in many cultures, sexuality remains a sensitive and taboo subject, particularly within family settings. The lack of comprehensive parental involvement in sexual education further strengthens students' reliance on these digital resources. They seek information about sexuality through digital platforms such as websites, social media, and apps, which offer easy and anonymous access to various sources.

Published: February 2025

This study aims to analyze the level of political participation in the upcoming 2024 Simultaneous Regional Head Elections in West Sulawesi Province. A mixed-method approach was employed, combining quantitative surveys and qualitative interviews to assess the political participation index and patterns of participation behavior. The research was conducted from January to April 2024, focusing on participants aged 20 years and above, all of whom were registered voters. The target population included active voters from various districts in West Sulawesi, using stratified sampling to ensure demographic and geographic representation. The sample comprised 122 survey respondents and 15 key informants selected purposively based on their roles in the electoral process. Results indicate that political participation is projected to increase compared to previous elections, though gaps remain between districts. Districts with better access to information and local leaders’ involvement show higher participation. Factors influencing participation include: (1) demographic factors, with the 30–45 age group showing higher participation, while younger generations (under 30 years) demonstrate apathy; (2) socio-cultural factors, where traditional norms and the role of religious leaders influence voter mobilization; and (3) political factors, including trust in candidates and local issues such as infrastructure. Barriers to participation include a lack of political education, apathy due to dissatisfaction with government performance, and administrative issues. Efforts to enhance participation include community-based education and social media, although these have not been fully optimized.

This article delves into the causes of the 2008 financial crisis, particularly focusing on its inception marked by the collapse of the mortgage market, which cascaded into the bankruptcy of numerous banks. The crisis stemmed from volatile real estate prices, leading to loans being issued to borrowers without sufficient collateral, exacerbating insolvency. In Hungary, the situation was exacerbated as most housing loans were denominated in Swiss francs, causing repayment obligations to soar due to rapid fluctuations in the exchange rate. State intervention became imperative amidst rising insolvency rates. Motivated by a longstanding interest in the economic ramifications of low interest rates, the authors aim to probe the factors influencing loan repayment motivations. Their research centers on the evolution and functions of state interest rate regulation, while also scrutinizing late fees and interest provisions related to tax and civil law claims to evaluate their impact on timely payments. Embracing an interdisciplinary approach blending historical, economic, and legal perspectives, the article underscores the necessity for well-calibrated regulatory interventions to mitigate the excesses of unrestricted free markets, especially in light of evolving global economic dynamics. It also underscores the importance of prudent regulations, given theories suggesting that persistently low interest rates may lead to economic distortions beyond a certain threshold, while acknowledging the constraints of interest rate adjustments.

Published: February 2025

The COVID-19 pandemic and the Movement Control Order (MCO) have had a negative impact on the financial well-being and digital well-being of B40 or small household income families in urban areas. In responding to the crisis, the government had launched multiple assistance programs to assist the group. Hence, the study intends to examine the relationship of government assistance towards digital and financial well-being of the group. Utilizing survey, the study involved 417 respondents living at the Public Housing Project (PPR) residential areas in Kuala Lumpur—the capital of Malaysia. The data was analyzed using Smart PLS and the key findings were (1) government assistance programs significantly affect the digital well-being and financial well-being of B40 urban families. However, there is no significant relationship between financial well-being and digital well-being. Besides, the Importance-Performance Analysis (IPA) indicated that the importance of government assistance programs towards digital well-being performance is higher than financial well-being. The assistance programs offered by the government plays essential role to ease the digital and financial constraints of B40 urban families during a difficult time. Reforms to the government assistance programs, the empowerment of digital aid packages, and the enhancement of social security net initiatives for B40 urban families are necessary to enhance the group’s preparedness and resilience in the face of new shocks in the future.

Después de una emergencia ambiental relacionada con las lluvias, conocer las precipitaciones ocurridas en la zona de la emergencia en esas horas o día nos ayuda a determinar si se trató de un evento climático excepcional o regular. Esta información permite evaluar la responsabilidad de una organización en el contexto de la fiscalización ambiental por parte del gobierno. Este trabajo nos permitirá obtener de una manera correcta los valores de precipitaciones del Satélite GPM (Global Precipitation Measurement) que brinda datos con resolución de 0.1° equivalente a 10 km aproximadamente, y periodicidad de 30 minutos, mediante una plataforma web open access. Con fines educativos en la investigación, se exhiben tres escenarios de descarga de datos del satélite GPM, dos de estos escenarios presentan omisiones que resultan en inexactitudes, mientras que el tercer escenario se ejecuta de manera precisa. Los datos satelitales se procesaron a través del software ArcGis obteniéndose el valor de las precipitaciones y se realizó una correlación lineal comparándolos con los valores de precipitación de las estaciones meteorológicas convencionales del Servicio Nacional de Meteorología e Hidrología del Perú (SENAMHI) en las mismas ubicaciones geográficas y en el mismo día, obteniéndose un valor de correlación de Spearman de 0.4, 0.5 y 0.6 para el primer, segundo y tercer escenario respectivamente. Lo cual indica que el uso de los valores obtenidos del satélite GPM en un día puede ser confiable cuando es descargado de manera precisa y es recomendable su uso cuando se tengan zonas de estudio que están a una distancia mayor de 10 km de una estación meteorológica.

Published: February 2025

Based on the installation method, anchors classified into 2 groups, namely cast in place and post installed anchors. Based on the load transfer mechanism, post installed anchors can be categorized into two namely, mechanical anchors and adhesive anchors. Adhesive anchor system consists of steel inserted into holes drilled in the concrete, with a structural adhesive as the anchorage adhesive agent between the concrete and steel. Factors that can affect the strength of an anchor embedded in concrete include the diameter and spacing of the anchor edges and the quality of the concrete material used. This research was conducted by modeling post adhesive anchors embedded into concrete then subjected to tensile forces to determine the effect of using anchor edge spacing with varying anchor diameter and concrete quality on the tensile strength of the anchor based on theoretical calculations and Midas FEA NX modeling. The modeling that will be studied is a total of 64 samples, consisting of variations in anchor diameter of 10 mm, 12 mm, 16 mm, 19 mm, variations in anchor edge spacing of 60 mm, 75 mm, 130 mm, 250 mm, and variations in concrete quality of 20 MPa, 25 MPa, 30 MPa, 35 MPa.

Authors: Ferdianto Yohanes , Gondokusumo Onnyxiforus
Published: February 2025

One of the most important stages in implementing a construction project is the Cost Budget Plan (RAB), in Indonesia using the Work Unit Price Analysis (AHSP) which is regulated by the Ministry of Public Works as a guide in calculating the project cost budget plan. However, not all contractors use the AHSP method as a guide in estimating project costs. In this research, a comparative study was carried out on which method is more effective on the total value of project realization costs. This research was conducted on a mall project located in Bali. The work studied is plumbing work which includes clean, used, dirty and vent water. From the results of the research carried out, calculations using the AHSP method have a value of Rp. 347,618,312 while using the contractor method has a value of Rp. 352,986,279. These two makanethods are compared with the total project realization value of Rp. 351.160.225. The difference between these two methods is the coefficient of wages and materials. In the AHSP method the coefficient has been determined while the contractor method is based on experience on construction projects. From the results of the comparison of cost budget estimates, it can be concluded that the contractor's method is more effective in calculating the planned cost budget because the difference in costs from the contractor's method is closer to the total cost of project realization.
Abstrak
Salah satu tahap terpenting dalam pelaksanaan proyek konstruksi adalah Rencana Anggaran Biaya (RAB), di Indonesia menggunakan Analisa Harga Satuan Pekerjaan (AHSP) yang diatur oleh Kementerian Pekerjaan Umum sebagai pedoman dalam menghitung rencana anggaran biaya proyek. Akan tetapi, tidak semua kontraktor memakai metode AHSP sebagai pedoman dalam melakukan estimasi biaya proyek. Pada penelitian ini dilakukan studi komparasi metode mana yang lebih efektif terhadap nilai total biaya realisasi proyek. Penelitian ini dilakukan pada proyek mall yang berlokasi di Bali. Pekerjaan yang diteliti adalah pekerjaan plambing yang mencakup air bersih, bekas, kotor dan ven. Berdasarkan hasil penelitian yang dilakukan, perhitungan dengan menggunakan metode AHSP memiliki nilai Rp. 347.618.312 sedangkan menggunakan metode kontraktor memiliki nilai Rp. 352.986.279. Kedua metode ini dibandingkan dengan nilai total realisasi proyek sebesar Rp. 351.160.225. Adapun perbedaan kedua metode ini adalah koefisien upah dan bahan, pada metode AHSP koefisien sudah ditetapkan sedangkan metode kontraktor berdasarkan pengalaman pada proyek konstruksi. Berdasarkan hasil perbandingan estimasi anggaran biaya, maka dapat disimpulkan bahwa metode kontraktor lebih efektif dalam menghitung rencana anggaran biaya karena selisih biaya metode kontraktor lebih mendekati total biaya realisasi proyek.

Published: February 2025

The population growth in Bandar Lampung city is accompanied by an increase in vehicles, leading to a growing need for road space. The inadequate road conditions often cause traffic issues such as reduced speed and potential congestion. The bottleneck of Jl. Letjen Alamsyah Ratu Prawiranegara from 5.50 meters to 3.80 meters reduces the effective lane width. Macroscopic traffic analysis was conducted using four models: Greenshields, Greenberg, Underwood, and Bell. The macroscopic modeling results show that there is a reduction in capacity due to the reduction in effective lane width, accompanied by a decrease in vehicle speed considering VM, Dj, and Sff values. Shock wave analysis was also conducted, with results for Wednesday showing a demand of VA = 952 vehicles per hour and DA = 45 vehicles per kilometer, and an effective delay duration (r) of 1 minute. The wave shock analysis revealed backward forming shock wave (ωAB) = -0.90 km/h, backward recovery shock wave (ωCB) = -5.82 km/h, and forward forming shock wave (ωAC) = 5.15 km/h. The time from peak flow to the end of congestion (tp) was found to be 0.18 minutes, with a potential queue length (QM) of 17.76 meters. Given the queue length, it takes 1.44 minutes for the lane to normalize until the end of congestion.
Abstrak
Pertumbuhan penduduk kota Bandar Lampung tentu diikuti dengan pertumbuhan jumlah kendaraan. Secara tidak langsung membuat kebutuhan akan ruang gerak kendaraan semakin bertambah. Kondisi ruas jalan yang kurang memadai sering menyebabkan masalah lalu lintas seperti penurunan kecepatan dan potensi antrian. Penyempitan jalan di segmen Jl. Letjen Alamsyah Ratu Prawiranegara mengurangi lebar jalur efektif dari 5,50 m menjadi 3,80 m. Analisis terhadap karakteristik makroskopik lalu lintas dilakukan dengan empat model yaitu Greenshields, Greenberg, Underwood, dan Bell. Secara makro hasil pemodelan memberikan kesimpulan bahwa terjadi pengurangan kapasitas akibat pengurangan lebar jalur efektif disertai dengan berkurangnya nilai kecepatan kendaraan ditinjau dari nilai-nilai VM, Dj, dan Sff. Analisis gelombang kejut juga dilakukan, hasil analisis hari Rabu dengan permintaan arus VA = 952 smp/jam dan DA = 45 smp/km serta durasi efektif hambatan (r) = 1 menit menunjukkan adanya gelombang kejut mundur bentukan (ωAB) = -0,90 km/jam, gelombang kejut mundur pemulihan (ωCB) = -5,82 km/jam, dan gelombang kejut maju bentukan (ωAC) = 5,15 km/jam. Selang waktu dari kondisi arus jenuh hingga lokasi antrian berakhir (tp) diperoleh sebesar 0,18 menit dengan potensi panjang antrian (QM) sejauh 17,76 m. Dengan kondisi panjang antrian tersebut, perlu waktu penormalan lajur hingga antrian berakhir selama 1,44 menit.

Lean duplex cold rolled stainless steel beams are an alternative material in steel construction. This steel has a dual microstructure consisting of ferritic and austenitic phases, providing a combination of high mechanical strength and superior corrosion resistance. The cold rolled steel process plays an important role in ensuring accurate dimensions and good surface quality of these steel beams, while maintaining the desired mechanical properties. This study aims to determine the changes in flexural strength of square hollow beams against circular hollow beams that have been studied previously. In addition, this study evaluates the flexural strength equation of perforated beams in ASCE specification and validates the proposed modified equation from previous studies. A total of 120 numerical specimens having variations in cross-section and hole size as well as material temperature were made using the ABAQUS program. The numerical specimens were rectangular hollow section beams of lean duplex material. Numerical simulations were conducted to obtain the pure flexural strength value from the four-point loading method. The evaluation results show that the ASCE equation has not met the safety requirements while the proposed modified equation has met the safety requirements. The evaluation of the effect of hole shape showed that the majority of square holes had less flexural strength than circular holes.

Balok baja tahan karat canai dingin jenis lean duplex merupakan material alternatif dalam konstruksi baja. Baja ini memiliki struktur mikro ganda yang terdiri dari fase feritik dan austenitik, memberikan kombinasi kekuatan mekanis yang tinggi dan ketahanan terhadap korosi yang superior. Proses baja canai dingin memainkan peran penting dalam memastikan dimensi yang akurat dan kualitas permukaan yang baik dari balok baja ini, dengan mempertahankan sifat-sifat mekanis yang diinginkan. Penelitian ini bertujuan untuk mengetahui perubahan kekuatan lentur balok berlubang persegi terhadap balok berlubang lingkaran yang telah diteliti sebelumnya. Selain itu penelitian ini mengevaluasi persamaan kekuatan lentur balok berlubang pada peraturan ASCE dan memvalidasi persamaan modifikasi yang diusulkan dari penelitian sebelumnya. Sebanyak 120 spesimen numerik yang memiliki variasi penampang dan ukuran lubang serta temperatur material dibuat menggunakan program ABAQUS. Spesimen numerik yang dibuat yaitu balok berpenampang hollow persegi panjang dari material lean duplex. Simulasi numerik yang dilakukan untuk memperoleh nilai kekuatan lentur murni dari metode pembebanan four-point loading. Hasil evaluasi menunjukkan persamaan ASCE belum memenuhi syarat keamanan sedangkan persamaan modifikasi yang diusulkan telah memenuhi syarat keamanan. Hasil evaluasi pengaruh bentuk lubang menunjukkan 60% penampang berlubang persegi memiliki kekuatan lentur lebih kecil dari penampang berlubang lingkaran (maksimal 30% lebih kecil).

The characteristics of the underlying soil greatly influence the stability of building foundations. Clay and sandy soils are commonly used in civil construction, each with drawbacks. This study aims to enhance the shear strength of clay and sandy soils by adding Type C fly ash. Clay soil samples were taken from Cengkareng, West Jakarta, fly ash from steam power plant Paiton, Central Java, and sandy soil from Garut, West Java. Testing included index properties, atterberg limits, grain size analysis, compaction, triaxial, and direct shear. The results indicate that adding Type C fly ash can significantly increase sandy soil's shear angle and cohesion. In contrast, adding fly ash in clay soil tends to reduce the shear angle but increase cohesion. Assuming an everyday stress of 10 kg/cm², the shear strength of sandy soil increased by 11,91 % with a 20% Type C fly ash mixture, whereas the shear strength of clay soil decreased by 43,00 % with a 20% Type C fly ash mixture. The conclusion from this study indicates that Type C fly ash is more effective when used in sandy soil to enhance shear strength, and further research is needed to determine the optimal fly ash content for various soil conditions.

Stabilitas pondasi bangunan sangat dipengaruhi oleh karakteristik tanah di bawahnya. Dalam konstruksi sipil, tanah lempung dan pasir sering digunakan, namun keduanya memiliki kelemahan masing-masing. Penelitian ini bertujuan untuk meningkatkan kuat geser tanah lempung dan pasir melalui penambahan fly ash tipe C. Sampel tanah lempung diambil dari Cengkareng, Jakarta Barat, fly ash dari pembangkit listrik tenaga uap (PLTU) Paiton, Jawa Tengah, dan tanah pasir dari Garut, Jawa Barat. Pengujian meliputi index properties, atterberg limit, grain size analysis, kompaksi, triaxial, dan direct shear. Hasil menunjukkan bahwa penambahan fly ash tipe C dapat meningkatkan sudut geser dan kohesi tanah pasir secara signifikan, sedangkan pada tanah lempung, penambahan fly ash cenderung mengurangi sudut geser namun meningkatkan kohesi. Dengan asumsi tegangan normal 10 kg/cm², kuat geser tanah pasir meningkat sebesar 11,91 % pada campuran fly ash tipe C 20%, sedangkan kuat geser tanah lempung menurun sebanyak 43,00 % pada campuran fly ash tipe C 20%. Kesimpulan dari penelitian ini menunjukkan bahwa fly ash tipe C lebih efektif digunakan pada tanah pasir untuk meningkatkan kuat geser, dan penelitian lebih lanjut diperlukan untuk menentukan kadar fly ash yang optimal pada berbagai kondisi tanah.
Genesis of the Institution of Denunciation in the Theory and Practice of the Law of Treaties

International treaties throughout the history have always played a key role in regulating relations between states. However, the constant development of international law and the changing conjuncture of international relations have led to both the conclusion and withdrawal from international treaties. The doctrine of international law, including the history of international law and the law of treaties, focuses more on the procedures of signing, conclusion and entry into force of international treaties, while the issues of termination of international treaties have less attention from international legal scholars. The relevance of the topic of denunciation of international treaties is due to both the difficulties arising in the exercise of the right to denunciation and the need for a detailed international legal regulation of this process. In order to identify the essential characteristics of the institution of denunciation of international treaties, the article conducts a comprehensive historical and legal analysis using the methods of comparative legal research. The novelty of this article lies in systematizing the evolution of the right to denunciation of international treaties from exogenous to endogenous character, as well as in identifying the influence of political factors on its practical implementation. For the first time, these developments are considered in the context of the fundamental principle of the law of treaty - pacta sunt servanda. It is noted that the institution of denunciation of international treaties has undergone significant evolution since ancient times. The key role in its formation was played by the London Convention of 1871 and the Vienna Convention of 1969. These documents were used to develop the periodization of the right to denunciation, which includes three stages. The existing international legal framework regulates the application of the right of denunciation in a non-exhaustive manner, resulting in a fragmented practice. Further development of this institution requires the unification of norms and mechanisms of control of the right to denunciation to prevent abuse of this right and to ensure the stability of international treaties.

Secara sosial, bahasa digunakan masyarakat untuk membangun dan mempertahankan hubungan sosial. Secara kultural, bahasa digunakan masyarakat untuk mengekspresikan budaya yang diciptakannya. Karena budaya antara satu masyarakat dengan masyarakat lainnya berbeda maka bahasa yang digunakan untuk mengekspresikannya juga berbeda. Salah satu bahasa yang memiliki perbedaan gender adalah bahasa Jepang. Data yang diteliti berfokus pada jenis kandoushi, kategori kandoushi berdasarkan gender penutur. Tujuan penelitian ini adalah untuk mendeskripsikan bentuk kandoushi doui yang digunakan oleh penutur pria dan penutur wanita. Alasan memilih penelitian ini adalah penelitian yang membahas penggunaan kandoushi pada danseigo dan joseigo masih belum banyak dilakukan. Penelitian ini dilakukan dengan pendekatan kualitatif dengan sumber data anime Dr. Stone karya Riichiro Inagaki musim satu yang dirilis pada bulan 5 Juli 2019 dan terdiri atas 24 episode. Data dianalisis menggunakan teori milik Masuoka dan Takubo. Ditemukan total 71 data  kandoushi jenis doui dengan bentuk hai (はい), Ee (ええ), Aa (ああ) Un (うん), dan Haa (はあ). Dari data tersebut ditemukan bahwa penutur pria cenderung menggunakan kandoushi Aa (ああ) sedangkan penutur wanita cenderung menggunakan kandoushi Un (うん) ketika setuju terhadap ucapan lawan tutur.
