Palm oil waste (by product)can be used as a potential feed for livestock. Nevertheless, the study research of the effect of Palm oil waste (by product) as a feed to the bull performance was limited. The purpose of this research is to get technology to improve semen quality through improving protein ofÂ feed based on palm oil waste (byproducts). This research was conducted in PTPN 6 Jambi andÂ used 30 bulls that separated into 3 treatments, treatment I (feed protein 12% and suplementation), treatment II (feed protein 12%) and treatment III (existing feed, feed protein 10%). Parameter were measured i.e feed consumption, libido, sperm motility, mass movement, sperm concentration, sperm abnormality, volume, pH, consistency, colour, body condition score and average daily gain. Design of this research was completely randomized design. Data was analyzed use ANOVA. The result showed that there is no significantly different on semen quality between treatmens. Semen quality of three treatments were appropriate to standart of quality semen of bull (sperm abnormality <20%, sperm motility >50% and sperm concentration >500 million/ml). Based on this consideration, feed with protein level 10% more efficient because it needs less cost but results a good semen quality. The conclusion of this research is protein level 10% can supporting performance reproduction of bull.

Aktivitas ekonomi di masyarakat tidak terlepas dari uang yang mampu mempengaruhi pertumbuhan ekonomi. Uang yang beredar terlalu banyak di masyarakat dapat mengakibatkan terjadinya inflasi, sedangkan terlalu sedikit uang yang beredar mampu memperlambat pertumbuhan ekonomi. Upaya untuk mengatasi permasalahan tersebut adalah memastikan ketersediaan uang kartal berdasarkan aliran uang masuk (inflow) dan aliran uang keluar (outflow) di Bank Indonesia melalui prediksi yang akurat. Metode FBProphet diimplementasikan dalam penelitian ini untuk meramalkan inflow dan outflow regional Bank Indonesia di Provinsi DKI Jakarta. Data yang digunakan dari periode tahun 2011-2023 menggunakan frekuensi bulanan, dengan data pelatihan dari tahun 2011-2022 dan sisanya sebagai data uji. Hasil evaluasi kinerja berdasarkan metrik MAPE dengan menerapkan metode prophet secara basic, menunjukkan tingkat akurasi pada inflow tergolong wajar, sedangkan pada outflow tergolong tidak akurat. Penerapan komponen hari libur, khususnya berupa dataframe holidays, mampu meningkatkan kinerja metode prophet dengan selisih MAPE sebesar 15.89% pada inflow, sehingga menjadi 25.06%, sedangkan pada outflow menjadi 34.57% dengan selisih MAPE sebesar 25.05%. Penerapan hyperparameter tuning dengan Bayesian optimization juga mampu meningkatkan kinerja metode prophet lebih optimal serta menunjukkan bahwa komponen hari libur yang optimal diterapkan pada inflow adalah dataframe holidays dan country holidays, sedangkan pada outflow hanya dataframe holidays. MAPE yang dihasilkan dari penerapan Bayesian optimization, pada inflow menjadi 21.18% dengan selisih sebesar 19.77%, sedangkan pada outflow menjadi 29.78% dengan selisih sebesar 29.84%.

This study aims to analyze the impact of using Zep Quiz as a game-based assessment medium on students’ reading comprehension skills in English learning. The study is grounded in the need for more engaging and interactive assessment innovations to address students’ boredom and anxiety when facing conventional tests. The research employed a quasi-experimental design with a non-equivalent control group, involving two tenth-grade classes at SMK Kosgoro Nganjuk. The experimental group was assessed using Zep Quiz, while the control group took a traditional paper-based test. Data were collected through a reading comprehension test and a learning motivation questionnaire. The findings indicate that the experimental group’s average score (78.5) was slightly higher than that of the control group (76.1), although the difference was not statistically significant (p = 0.254). Nevertheless, the use of Zep Quiz was proven to enhance students’ motivation, engagement, and comfort during the assessment process. Interactive features such as avatars, real-time feedback, and a competitive atmosphere helped reduce anxiety and foster a stronger learning spirit. These results suggest that Zep Quiz serves as a valid, enjoyable, and academically reliable digital assessment alternative.

Teacher–student interaction plays a critical role in shaping learning experiences, influencing students’ cognitive, emotional, and communicative development. This study aims to synthesize findings from recent empirical and conceptual studies through a Systematic Literature Review (SLR) focusing on discourse analysis in English language classrooms. A total of selected articles published between 2020 and 2025 were reviewed to identify patterns, power relations, communicative strategies, and pedagogical implications of classroom discourse. The findings reveal that teacher talk remains dominant in many contexts, characterized by directive speech, display questions, and limited dialogic space. However, several studies highlight the importance of fostering student-centered communication, utilizing technology to enhance interaction, and understanding cultural dynamics in shaping classroom discourse. Power relations, emotional contagion, and deixis were found to significantly influence participation and meaning-making processes. Moreover, discourse-based instructional models and critical discourse analysis approaches demonstrate potential in encouraging reflective pedagogy and communicative competence. Overall, this review underscores the need for teachers to develop awareness of linguistic choices and interactional patterns to build inclusive, dialogic, and empowering learning environments. The synthesized insights offer practical implications for educators, policymakers, and curriculum designers aiming to improve teaching practices and enhance student engagement.

Persaingan pada industri pariwisata digital menuntut perusahaan untuk memahami perilaku pelanggan secara lebih mendalam. PT Travlr Guides Indonesia saat ini masih menerapkan pendekatan pemasaran yang bersifat umum dan belum memanfaatkan data transaksi pelanggan secara optimal, sehingga berpotensi menyebabkan strategi promosi tidak terarah, tingkat keterlibatan pelanggan rendah, serta kecenderungan pelanggan beralih pada pesaing. Penelitian ini bertujuan untuk melakukan segmentasi pelanggan PT Travlr Guides Indonesia berdasarkan perilaku transaksi berbasis model RFM (Recency, Frequency, dan Monetary) dengan kerangka kerja Knowledge Discovery in Database (KDD). Data yang digunakan berupa data transaksi pelanggan PT Travlr Guides Indonesia melalui platform Thebalibible pada periode Januari 2024 hingga Februari 2025. Hasil penelitian menunjukkan jumlah optimal klaster sebanyak tiga klaster. Algoritma Possibilistic Fuzzy C-Means (PFCM) menghasilkan nilai Silhouette Coefficient (SC) sebesar 0.468 dan Davies-Bouldin Index (DBI) sebesar 0.811. Algoritma Equilibrium K-Means (EKM) menunjukkan kinerja yang lebih baik berdasarkan nilai SC sebesar 0.477 dan DBI sebesar 0.781, sehingga hasil segmentasi algoritma EKM akan digunakan sebagai dasar perumusan rekomendasi strategi pemasaran. Berdasarkan hasil tersebut, terbentuk tiga segmen pelanggan yang meliputi segmen at risk customers, segmen loyal customers, segmen low-value customers.
