Abstract

Waterfalls in Mount Halimun Salak and Babakan Madang serve as critical water sources for Bogor residents, necessitating environmental monitoring using aquatic insect bioindicators. This study identified and compared aquatic insect communities across these waterfalls to assess water quality. EPT orders (Ephemeroptera, Plecoptera, Trichoptera) were prioritized as bioindicators due to their sensitivity to physicochemical changes and association with clean water. Purposive sampling was conducted along 10-meter transects at three stations per location with three replications. Samples were collected using hand nets and preserved in 70% alcohol. Environmental parameters measured included humidity, water temperature, TDS, current velocity, and pH. Specimens were identified using stereo microscopes, reference materials, and the Waterbug Application. Data analysis employed Shannon-Wiener Diversity Index, EPT abundance metrics, NMDS ordination, and BMWP-ASPT Index. Results revealed higher individual counts at Babakan Madang, while Mount Halimun Salak demonstrated greater species diversity. The abundance of EPT is dominated by the Baetidae Family. NMDS Ordination shows the distribution of families in 6 observation stations. Based on the measurement of the BMWP-ASPT Index, the Mount Halimun Salak and Babakan Madang waterfalls have moderately polluted water quality. These findings highlight the importance of continued biomonitoring to protect these vital freshwater resources for local communities.

Abstract

Diabetes is a disease caused by insulin dysfunction or impaired insulin production, leading to elevated blood glucose levels (hyperglycemia). It is classified into three types: Type 1, Type 2, and Gestational Diabetes Mellitus (GDM). Type 2 diabetes is a condition resulting from insulin resistance. Previous research has identified microorganisms isolated from Ficus deltoidea that produce α-glucosidase inhibitors. This study aims to determine the potential of extracts derived from Streptomyces tendae as an α-glucosidase inhibitor through both in-vitro and in-vivo assessments, specifically evaluating the extract's effectiveness in reducing blood glucose levels in Sprague Dawley rats with Type 2 diabetes. Although the isolates from previous studies showed a decrease in activity, they remained capable of lowering blood glucose levels in the rats. Statistical analysis of the Oral Glucose Tolerance Test (OGTT) provided sufficient evidence to conclude that the combination of time (minutes) and extract administration significantly influenced the reduction of blood glucose levels in diabetic rats (P<0.05). Diabetes was induced in the rats using low-dose streptozotocin. The results showed that "Dose 1" of the extract significantly reduced blood glucose levels compared to control (aquades) treatment starting from the fifth day of administration and was effective in suppressing further increases in blood sugar (P<0.05).

Abstract

Mawar (Rosa spp.) merupakan tanaman berbunga yang termasuk dalam famili Rosaceae. Mawar dianggap sebagai salah satu tanaman hias yang paling populer dan banyak diminati di berbagai sektor. Popularitas ini menyebabkan perlunya produksi mawar dalam skala besar, khususnya bunga potong hibrida. Penelitian ini bertujuan untuk mengidentifikasi komposisi media yang optimal untuk memproduksi mawar cv. Shangrila dalam jumlah besar dan dalam jangka waktu yang lebih singkat, terlepas dari perubahan musim. Penelitian ini menggunakan Rancangan Acak Lengkap (RAL), dengan sembilan kali ulangan untuk semua perlakuan kecuali perbanyakan tunas aksiler. Eksplan yang digunakan adalah ruas batang dengan satu buku. Setelah sterilisasi, eksplan dikulturkan pada media Murashige dan Skoog (½ MS) setengah kekuatan tanpa zat pengatur tumbuh selama satu minggu. Langkah ini dimaksudkan untuk mengevaluasi efektivitas antibiotik yang digunakan selama tahap akhir proses sterilisasi. Hasil penelitian menunjukkan bahwa BAP pada konsentrasi 3 mg/L menghasilkan jumlah tunas tertinggi. Komposisi media yang sama, tanpa ekstrak kecambah kacang (B3T0), menghasilkan persentase pembentukan tunas tertinggi dan panjang tunas terbesar. Media perakaran yang optimal adalah campuran pasir dan vermikulit 1:1, yang dilengkapi dengan nutrisi dari larutan ½ MS tanpa penambahan auksin.

Abstract

Serangga memiliki berbagai peran di alam, seperti polinator, predator, dan mangsa. Interaksi antara serangga dengan tumbuhan berbunga merupakan elemen penting dalam mendukung proses reproduksi tanaman. Penelitian ini bertujuan untuk menganalisis keanekaragaman serangga pengunjung dan analisis pemisahan temporal kunjungan serangga pada bunga tanaman jagung di Kebun Cikabayan IPB, Dramaga, Bogor. Pengamatan keanekaragaman dilakukan dengan metode Visual Encounter Survey (VES) pada bunga pertanaman jagung selama 15 menit pada pukul 07.00–09.00 dan 15.00–17.00 pada fase generatif dan fase pasca-generatif.Pengamatan serangga pengunjung bunga jagung didapatkan 26 morfospesies yang termasuk dalam 8 ordo dan 22 famili. Tiga famili serangga dominan mengunjungi bunga jagung adalah Apidae, Vespidae, dan Formicidae. Spesies pengunjung terbanyak adalah lebah madu (Apis cerana, 83 individu). Hasil analisis menunjukkan tidak ada pemisahan temporal komposisi serangga pada perbedaan waktu dan fase pembungaan. Hasil NMDS menunjukkan pada fase pasca-generatif terdapat kecenderungan pemisahan waktu kunjungan pad pagi dan sore hari.

Abstract

Bama Beach is one of the tourism areas in Baluran National Park (BNP), which is also a habitat for long-tailed macaques (Macaca fascicularis). This species is commonly found with aggressive behavior and bravery towards humans at Bama Beach. The aim of this study is to determine the level of interaction that occurs between LTM and humans at Bama Beach, BNP. The method used was a survey questionnaire (Likert scale) and also field observations to support the results of the interaction level in May 2023. Questionnaire data collection is aimed at visitors (64 respondents) and BNP staff (six respondents). While field observations were collected by scan sampling methods during seven days. There are seven categories of interaction that were observed, i.e., proximity, physical contact without being aggressive, taking humans' stuff, intimidating, chasing or lunging, facial or voice threats, and biting or scratching. The results of the questionnaire based on a Likert scale obtained an average index value of 34.25% (mild interaction). The resulting interaction level is supported by the acquisition of the percentage of interaction categories based on field observations, namely the proximity interaction, which has the highest value (44%). Whereas, we also found the threatened interaction to humans, including intimidating (20%), facial or voice threats (16%), taking humans' stuff (14%), and chasing or lunging (5%).
