This study aims to analyze the effect of share allocation to institutional investors, auditor reputation, and underwriter reputation on the level of underpricing in initial public offerings (IPOs) on the Indonesia Stock Exchange during the period 2016–2020. Using a purposive sampling method, this study analyzed 120 companies conducting IPOs. Data were analyzed using multiple linear regression to test the relationship between independent variables and the level of underpricing. The results showed that share allocation to institutional investors had a significant negative effect on the level of underpricing, indicating that institutional investor participation can reduce information asymmetry. In addition, auditor reputation had no effect on underpricing, while underwriter reputation showed a significant negative effect on the level of underpricing, meaning that the presence of highly reputable parties can increase market confidence in companies conducting IPOs. Control factors, such as company size and company age, also affect the level of underpricing although their contribution is relatively smaller compared to the main variables.

Kajian ini menyimpulkan bahwa pola tafsir maqâṣid merupakan penafsiran yang berlandaskan penafsiran moderat dengan pijakan utamanya adalah tujuan Al-Qur’an dan syariat dengan berlandaskan pada lima langkah, yaitu: 1) Identifikasi Ayat. Tahap ini menggambarkan tiga fitur; holistik, interrelasi hierarki, dan kebermaksudan; 2) Identifikasi Makna. Tahap ini, menelusuri makna ayat primer, yang bertujuan memperoleh spirit ayatnya; 3) Eksplorasi Maqāșidasy-Sharî‘ah. Tahap ini menjadi ciri khas pendekatan Maqāșid asy-Shari’ah dalam menafsirkan Al-Qur’an, karena maqâṣid al-Shari’ahal-khâssah bakal digunakan sebagai wawasan penghubung dua konteks yang diambil dari ayat sekunder; 4) Kontekstualisasi Ayat. Proses ini mengacu kepada Maqāșid asy-Shari’ah yang sebelumnya telah dilakukan eksplorasi; 5) Penarikan Kesimpulan. Studi literatur ini mempertegas bahwa pola tafsir maqasidi juga mengacu pada komponen-komponen yang harus ada dalam dunia tafsir Al-Qur’an, yaitu 1) Penjelasan; 2) Maksud firman Tuhan; 3) Sesuai kemampuan manusia. Dengan ketiga komponen tersebut muncul konsekuensi khusus dalam suatu proses penafsiran atas Al-Qur’an. Sebuah pola penafsiran yang relevan dengan perkembangan zaman

Kamuflase merupakan salah satu bentuk adaptasi morfologis makhluk hidup agar tidak dapat dikenali oleh pemangsa dengan mengatur warna tubuhnya sesuai dengan latar belakang objek di lingkungannya. Keragaman hewan yang memiliki kemampuan kamuflase salah satunya dapat diamati pada batang pohon. Jenis pohon dengan warna dan struktur berbeda dapat menjadi tempat hidup bagi spesies dan tingkat kamuflase yang berbeda pula. Salah satu tempat dengan keragaman flora dan fauna yang tinggi dan masih terlindungi adalah di Taman Hutan Raya Ir. Djuanda. Tujuan penelitian ini adalah untuk mengetahui bentuk adaptasi kamuflase dan kesesuaian morfologi hewan yang hidup pada dua jenis batang pohon yaitu Pterygota horsfieldii dan Khaya anthotheca pada tiga plot berbeda di Taman Hutan Raya Ir. Djuanda, Bandung. Data diambil dengan metode VES (Visual Encounter Survey) dengan mengambil gambar menggunakan kamera HP Xiaomi Redmi Note 10s. Hasil dokumentasi yang diperoleh kemudian dianalisis rata-rata nilai RGB (Red, Green, Blue) menggunakan perangkat lunak ImageJ untuk mengetahui nilai Euclidean Distance. Hasil penelitian menunjukkan terdapat beberapa famili hewan yang diidentifikasi dengan nilai rata-rata RGB yang paling mendekati rata-rata RGB pohon pada plot 1, 2, dan 3 secara berturut-turut adalah famili Gryllidae, Araneidae, dan Formicidae. Selain itu, nilai Euclidean Distance terkecil ada pada plot 3 yang menunjukkan tingkat kamuflase hewan yang paling baik. Dengan demikian, dapat disimpulkan bahwa perbandingan nilai rata-rata RGB hewan dan rata-rata RGB pohon tidak berbeda jauh pada ketiga plot. Hal itu menunjukkan bahwa seluruh hewan pada ketiga plot memiliki kemampuan kamuflase yang baik.

Whip smut symptoms have emerged in sugarcane plantations in Central Lampung Regency, Lampung Province. However, the identity of the pathogen and its sensitivity to various fungicidal active ingredients remain unclear. This study aims to identify the whip smut pathogen in sugarcane plantations in Central Lampung Regency and evaluate its sensitivity to different fungicidal active ingredients.The research involved morphological and molecular identification of the pathogen, along with sensitivity testing against fungicides containing carbendazim, prochloraz, and mancozeb, as well as plant-based fungicides derived from puyangan (Zingiber zerumbet) and jamuan (Curcuma zedoaria) extracts. Morphological analysis revealed that the whip smut pathogen has septate hyphae, cylindrical sporidia measuring 7.45–18.31 µm in length and 1.63–3.89 µm in width, and round, yellowish-brown teliospores with an average size of 6.39 × 6.66 µm. Molecular identification confirmed that the LA UKN isolate from Central Lampung Regency belongs to Sporisorium scitamineum, with a bootstrap value of 93%. Sensitivity testing indicated that the pathogen is highly susceptible to carbendazim and prochloraz but less sensitive to mancozeb, puyangan extract, and jamuan extract.

Pests in sugarcane plantations are a major cause of damage, which could lead to severe damage to the crop, reduction of sugar quality, and significant economic loss. One of the major pests known in sugarcane plantations is stem borer (Chilo sacchriphagus), which attacks the canes. Two primary parasitoids, Trichogramma chilonis, which predates the stem borer eggs, and the Jatiroto fly (Diatraeophaga striatalis), which predates the stem borer larvae, are discussed here. This paper presents a time-dependent ten-dimensional dynamical mathematical model consisting of four-stage stem borer compartments, three-stage Trichogramma compartments, and three-stage Jatiroto compartments. Simulations are presented to describe the phenomenon of Trichogramma predation, Jatiroto predation, and simultaneous predation of both predators. It is shown that the release rate of each predator and a combined release of two predators can significantly reduce the infestation levels to a tolerable level for sugarcane production. The oscillatory dynamics of the stem borers and the Jatiroto flies affected the release timing strategy based on the level of infestation in the field. The results are expected to help us better understand the predator-prey phenomenon in the field and improve the forecasting of infestations in the field.
