    Green open space (RTH) is one of the important elements of the city and can be accessed by the community, which functions as ecological, socio-cultural, architectural, and economic. Physically, green open space (RTH) can be divided into natural green open space in the form of natural wild habitats, protected areas, and national parks, as well as non-natural or built green open spaces such as parks, sports fields, cemeteries, or green roads. In the green open space, there are plants that grow and are useful, among which there are different types of plants planted, namely tree plants, shrubs, vines, and herbal plants. One of the functions of tree vegetation in Green Open Space (RTH) is to help absorb GHG emissions. This study aims to identify the characteristics of vegetation in the education corridor on Jalan ZA Pagar Alam Bandarlampung and identify vegetation absorption in the education corridor on Jalan ZA Pagar Alam Bandarlampung to see the availability of green lanes as green open space in the Education Area Corridor at Jalan ZA Pagar Alam Bandarlampung. In this case, data collection was carried out through primary data collection with observation collection techniques to determine the characteristics and amount of tree vegetation, and the analysis carried out was descriptive quantitative with the calculation of the central tendency, namely the mean and mode. Based on the results of the analysis, the education corridor on Jalan ZA Pagar Alam has the availability of 782 individual tree vegetation with 31 tree vegetation characteristics, and the most abundant tree vegetation characteristics are Pometia pinnata or matoa trees. The characteristics of the existing trees have their respective uptake capabilities. In the education corridor, Jalan ZA Pagar Alam has an absorption capacity of 37.66 tons/day or 1,129.79 tons/month or 13,557.46 tons/year from 782 individual trees with different characteristics. which has the largest absorption, namely palm trees, with an absorption capacity of 27.41 tons/day, or 822.31 tons/month, or 9,867 tons/year

    ABSTRAKSI: Sistem information retrieval dikatakan ideal jika sistem dapat menemukan seluruh dokumen yang relevan saja tanpa dokumen yang tidak relevan, namun adanya varian morfologik yang bermacam-macam seperti accelerate, accelerated, acceleration tidak dianggap satu morfologi yaitu accelerate, sehingga teknik stemming perlu diterapkan pada sistem information retrieval untuk mengubah varian morfologik dari term-term menjadi sebuah bentuk kata sehingga dianggap ekuivalen oleh sistem selain itu juga mampu mengurangi ukuran index file retrieval dan untuk meningkatkan keakuratan retrieval (efektifness). Pada tugas akhir ini penulis engimplementasikan lovins stemmer dan Porter stemmer serta melakukan modifikasi dengan menggabungkan Lovin-Porter stemmer, saat stem hasil dari algoritma porter dibandingkan dengan term awal hasilnya sama maka dilakukan proses stemming menggunakan algoritma lovin (dapat diistilahkan penggabungan secara seri). Pada tugas ini dilakukan pula analisis pengaruh penerapan stemming. Hasil penelitian menunjukkan bahwa dengan stemming sistem mampu mereduksi term yang dihasilkan sehingga mampu mengurangi ukuran index file walau akurasi term yang dihasilkan tidak 100% menemukan bentuk root dari morfologi setiap kata. Dari sudut pandang performansi sistem bisa dikatakan penerapan algoritma modifikasi Lovin-Porter lebih baik dibanding algoritma Porter dan Lovin dimana nilai precision yang dihasilkan rata-rata menunjukkan peningkatan.Kata Kunci : Stemming, Information Retrieval, Precision, Recall, Algoritma Lovin, Algoritma Porter, Modifikasi Algoritma Lovin-PorterABSTRACT: Information Retrieval system ideal if the system can find all relevant document without retrieved non relavant. Variation morphology in English word can be likes accelerate, accelerated, acceleration. The fact they are one conflation of accelerate, this is the stemming needed on the information retrieval system. For changed variation morphology from terms to be a root word and readed as one class conflation with the system and to increasing efectiveness, we the author with affix removal stemmer algorithm lovin,porter and the modification of lovin and porter (Lovpot), from the testing with measure of accuracy. In this paper, writer implements Lovin’s stemmer and Porter’s stemmer also doing modification by combining Lovin-Porter stemmer, if stem result from porter algorithm is compared with earlier term. That’s had a conclusion that’s accuracy term stemmed its not 100% found the morfology of root word. And with performance and strength measure lovpot algorithm performance is better than porter and lovin cause the precision average of lovpot show increasing.Keyword: Stemming, Information Retrieval, Precision, Recall, Algoritma Lovin, Algoritma Porter, Modifikasi Algoritma Lovin-Porte

    This study aims to determine the effectiveness of the Takeshima/Dokdo Island dispute resolution mechanism between Japan and South Korea through non-juridical channels. The dispute has been started since the Japanese occupation in South Korea, so in this paper the author wants to examine the dispute resolution mechanism that has been carried out by Japan and South Korea in their efforts to resolve the Takeshima/Dokdo Island dispute. This type of research is normative legal research that emphasizes the approach to legislation. The results of this study indicate that the settlement mechanism carried out by Japan and South Korea using non-judicial channels is still not effective. The two countries have negotiated twice, namely in 1998 and 2006. In the same year as the second negotiation, South Korea decided to free itself from the UNCLOS dispute resolution. Then in 2018 Japan established a permanent connection to the island of Takeshima/Dokdo. South Korea's refusal to take the dispute to the International Court of Justice and the failure of negotiations, have left ambiguity over the ownership status of Takeshima/Dokdo islands.Penelitian ini bertujuan untuk mengetahui efektivitas mekanisme penyelesaian sengketa Pulau Takeshima/Dokdo antara Jepang dan Korea Selatan melalui jalur non-yuridis. Sengketa tersebut telah dimulai sejak zaman pendudukan Jepang di Korea Selatan, sehingga pada tulisan ini penulis ingin meneliti mekanisme penyelesaian sengketa yang telah dilakukan oleh Jepang maupun Korea Selatan dalam upayanya menyelesaikan sengketa Pulau Takeshima/Dokdo. Jenis penelitian ini adalah penelitian hukum normatif yang menekankan pada pendekatan peraturan perundang-undangan. Hasil dari penelitian ini menunjukkan jika mekanisme penyelesaian yang dilakukan Jepang dan Korea Selatan menggunakan jalur non-Yudisial, masih belum efektif. Kedua negara telah melakukan negosiasi sebanyak dua kali, yakni di tahun 1998 dan tahun 2006. Pada tahun yang sama dengan negosiasi kedua, Korea Selatan memutuskan untuk membebaskan diri dari penyelesaian sengketa UNCLOS. Kemudian Jepang di tahun 2018 mendirikan permanen terkait pulau Takeshima/Dokdo. Penolakan Korea Selatan untuk membawa sengketa ke Mahkamah Internasional serta ketidak berhasilan negosiasi, membawa ketidakjelasan bagi status kepemilikan pulau Takeshima/Dokdo)

ABSTRACT In reading and understanding the Heritage Book text, Arabic qowaid skills are urgently needed, especially Qowaid Shorof. In qowaid shorof, it is also needed the ability to understand Al-Amtsilah At-Tashrifiyyah, namely the ability to repeat and remember changes in sentences and meanings from one form to another, which by having a good ability to understand Al-Amtsilah At-Tashrifiyyah, then will easily read the heritage book well too. Especially in giving meaning and understanding the contents of the text conveyed by the Author of the book to the reader. So that the ability to understand Al-Amtsilah At-Tashrifiyyah is the most important thing in the learning of the knowledge of the religion, especially in applying to the skill of reading Arabic texts, such as the heritage book. Likewise what happened in the An-Najah Mamba'ul Ma’arif Denanyar Jombang Islamic School, the ability of students to read and understand the text of the heritage book is in accordance with the ability to understand the AL-Amtsilah At-Tashrifiyyah that they have. That is, when students are good at understanding Al-Amtsilah At-Tashrifiyyah, their ability to read heritage text is good, and vice versa. The purpose of this research were to: (1) Know the Ability of Students in understanding Al-Amtsilah At-Tashrifiyyah in the An-Najah Mamba'ul Ma'arif Denanyar Jombang Islamic School (2) Knowing the Student's Ability to Read the Heritage Book in the An-Najah Mamba'ul Ma'arif Denanyar Jombang Islamic School (3) Knowing whether there is a relationship between understanding Al-Amtsilah At-Tashrifiyyah and Student Ability to Read Heritage Books at An-Najah Mamba'ul Ma'arif Denanyar Jombang Islamic School. The approach used in this research is a quantitative approach to the type of correlation. In data collection, researchers go through the following stages: written examinations in the two aspects above and documentation. Then proceed with testing the hypothesis through product moment correlation analysis. The results of this research indicate that: (1) Understanding Ability of Al-Amtsilah At-Tashrifiyyah Students in the An-Najah Mamba'ul Ma'arif Denanyar Jombang Islamic School, based on the results of data analysis on 47 respondents, with very good categories, with a percentage of 87,2%. (2) Students' Ability to Read the Heritage Book in An-Najah Mamba'ul Ma’arif Denanyar Jombang Islamic School, based on the results of data analysis on 47 respondents, in the good category, with a percentage of 74.8%. (3) The correlation test between the two variables states that the sigificance value is 0,000. If the significance value is smaller than 0,05 then between the two variables there is a relationship. While the value of rxy = 0,793. This states that there is a correlation between the ywo variables, with the correlation level being high.

    This study is motivated by the nature of human beings born on the earth as khalifatu fi al-ard or as a leader. In this case, humans are expected to not only be their own leaders but also be leaders in managing, maintaining and managing the earth properly in all aspects of life. However, in the midst of this distribution era, this did not happen. This happens because the current development is so fast and advanced. The main key in this case is the choice or application of leadership models. Basically, the leadership model is diverse, but there is an interesting leadership model to study, namely prophetic leadership. To get data relevant to this problem the author uses descriptive analysis method, namely by providing a clear picture of the concept of prophetic leadership which includes, definitions, principles, nature and types of prophetic leadership. The results of the study show that this leadership model is ideal for implementation in daily life, because this model, was first applied by the Prophets of his time. In addition, the attributes of the Prophet also inspire leadership. Thus, it is expected that leaders can uphold these traits so that they can become good role models in all aspects of life both in society, nation and country

    بسم الله الرحمن الرحيم In the Name of Allah, Most Gracious, Most Merciful THE ROLE OF INDEXING FOR A JOURNAL Islamic economics, banking and finance is still a niche area of research. The number of journals publishing Islamic finance literature has grown since the first academic journal dedicated to Islamic finance was launched in 1983 by King Abdulaziz University in Saudi Arabia. Yet, it should be recognised that the number remains small compared to their conventional counterparts. There are only a few specialised academic journals that publish literature in areas related to Islamic accounting, economics, business, banking, finance and management. As at September 2023, less than ten such journals are Scopus-indexed and only one is included in Clarivate Analytics’ Web of Science Social Sciences Citation Index (SSCI). Indexation of a journal in prestigious databases is a reflection of the journal’s quality and impact. Indexed journals are recognised as authoritative sources of information and are considered of higher scientific quality than non-indexed journals. By getting indexed and abstracted in major indexes and databases, journals gain international visibility and become more accessible to their readers. This paves the way for published articles to be seen by more readers and cited more often by scholars. Therefore, the more visible a journal is, the more authors’ articles will be seen, read and cited and the greater the opportunity for the journal to contribute to the wider scholarly community within its field of specialisation. A major index is Scopus, Elsevier’s abstract and citation database. Scopus-indexed journals have been evaluated and accepted by the Scopus Content Selection and Advisory Board (CSAB) for meeting rigorous quality and impact criteria. Scopus’ minimum assessment criteria include peer-reviewed content, regular and timely publication, relevance to an international audience, and ethical publication policies. Scopus-indexed journals are further categorised into four quartiles within their specific subject area. Quartile 1 (Q1) consists of the highly-ranked journals, having the highest level of quality and impact. It is then followed by Quartile 2 (Q2), Quartile 3 (Q3) and Quartile 4 (Q4). SSCI, another highly-regarded index that ranks the most prestigious journals in the social sciences stream, forms part of the ‘Web of Science Core Collection’, which also comprises the Science Citation Index Expanded (SCIE), Arts & Humanities Citation Index (AHCI) and Emerging Sources Citation Index (ESCI). The Web of Science Core Collection recognises only journals that demonstrate high levels of editorial rigour and best practices. For inclusion in SSCI, SCIE and AHCI, journals within the respective category (i.e., social sciences,  sciences, and arts and humanities) must meet both rigorous quality criteria and impact criteria. If a journal meets only the quality criteria, it enters the ESCI. Journals which enter ESCI are further evaluated for impact and are then included in either SCIE, SSCI or AHCI. Although there is no absolute rule, journals that fall within Q1 and Q2 are much more likely to be assessed for positive impact. According to the Web of Science Journal Evaluation Process, the quality criteria include:    ·  ISSN·  Journal title·  Journal publisher·  Website address and functionality·  Content access·  Peer review policy·  Contact details·  Scholarly content·  Content relevance ·  Article titles and abstracts in English·  Clear language·  Timeliness of publication·  Publication volume·  Journal format·  Publication ethics statement·  Bibliography·  Appropriate citations to the literature ·  Editorial affiliation details·  Editorial board composition·  Author affiliation details·  Author distribution·  Grant support details·  Validity of statements·  Adherence to community standards   ISRA International Journal of Islamic Finance (IJIF) is Scopus-indexed, and its latest quartile as at 5 September 2023 is Q1 (Development), Q2 (Finance) and Q2 (Economics and Econometrics). It is also included in ESCI, beginning with Vol. 9 No. 1 (2017). The ongoing challenge for IJIF is to maintain its rank within the top quartiles in Scopus by continuing to increase the number of citations of its published articles. IJIF’s final hurdle is to meet the Web of Science’s impact criteria so that it can be considered for inclusion in SSCI. These impact criteria include: Comparative Citation Analysis — this benchmarks IJIF’s impact factor against existing SSCI journals.   Author Citation Analysis — this checks that IJIF’s authors are regularly publishing in other SSCI journals. Editorial Board Citation Analysis — this checks that IJIF’s Editorial Advisory Board members are regularly publishing in other SSCI journals. Content Significance — this checks that significant and original contributions to the field are being published with regularity. Obviously, the challenge remains for IJIF to attract highly-cited papers, high profile authors whose work attracts citations, articles that discuss hot and emerging trends, and original research that contributes to the body of Islamic finance knowledge, among others. Necessary measures will be taken at the level of IJIF to improve its impact on the Islamic finance community.  IJIF Volume 15 Number 3 September 2023 This issue of IJIF publishes nine articles that have been long awaiting publication. We thank the authors for considering the publication of their articles with IJIF despite the long wait. The delay was regretfully caused by the pagination constraints we faced when publishing with our last publisher.

    Model of Land Cover Change Caused by Toll Road Access Using Cellular Automata in Sumatra Island

    Full text link
    The use of land is a part of the fulfillment of human needs. The establishment of a large-scale infrastructure project often triggers an increase in land cover around its infrastructure project. Most of the increase in built up land tends to occur in areas that are traversed by or located near main accessibility routes such as toll roads. Although the construction of toll roads can improve accessibility between regions, land is a limited resource. So that it becomes the basis for researchers to identify the changes in land use in regencies and cities on the island of Sumatra that are crossed by toll roads that have been operating. The goal of land use change analysis is to give a description or explanation, predict, look at the effects, and make a decision (prescription). This research was conducted by identifying the changes in the existing land cover and predicting the land cover using cellular automata. Cellular automata have proven to be a method that is suitable for predicting the dynamics of land use through spatial simulation. The results show that there was an increase in the amount of land built from early 2017 to 2030. The covered land is developed around the toll gate after it is actively operated. In all provinces studied, deviation discrepancies were found in the conservation and cultivation areas. Deviations that occur in conservation areas need to be considered as there should be no land built in these areas, which means that there are cultivation activities in the conservation areas
