Abstract

The Sumatran elephant (Elephas maximus sumatranus), classified as Critically Endangered, plays a vital role in maintaining tropical forest ecosystems. However, habitat degradation, fragmentation, and land conversion have escalated human and elephant conflicts in Sumatra. These conflicts cause severe economic losses, crop destruction, and over 200 elephant deaths between 2010 and 2023, mainly from poaching and retaliation. This review aims to examine mitigation strategies implemented in Bukit Barisan Selatan, Way Kambas, and Gunung Leuser National Parks, and to assess their effectiveness and sustainability. Using a literature review method, relevant scientific publications on elephant conflict mitigation were systematically analyzed. Findings indicate that combined structural and non-structural approaches such as sound deterrents, elephant trenches, tame elephant patrols, and community-based units (CRU and ERU) effectively reduce short-term conflicts. Long-term success, however, requires integrated, ecosystem-based strategies emphasizing habitat restoration, corridor connectivity, and adaptive land-use planning. This study highlights the need for humanistic and sustainable mitigation to foster coexistence between humans and Sumatran elephants.

Abstract

Capsicum chinense merupakan salah satu varietas cabai yang populer digunakan dalam masakan dan dikenal mengandung beragam senyawa bioaktif yang bermanfaat bagi kesehatan. Sebagian besar penelitian sebelumnya berfokus pada bagian buah, sementara tangkai yang berperan sebagai jalur transportasi nutrisi dan metabolit sekunder masih jarang dieksplorasi. Penelitian ini bertujuan untuk mengidentifikasi golongan metabolit sekunder yang terdapat dalam tangkai Capsicum chinense melalui skrining fitokimia. Sebanyak 50 gram serbuk tangkai cabai diekstraksi dengan metode maserasi menggunakan pelarut etanol 96% pada perbandingan 1:10 (b/v), kemudian filtrat diuapkan dengan rotary evaporator hingga diperoleh ekstrak kental. Ekstrak selanjutnya diuji secara kualitatif untuk mendeteksi keberadaan alkaloid, flavonoid, tanin, saponin, steroid, dan terpenoid. Hasil penelitian menunjukkan bahwa ekstrak tangkai Capsicum chinense memberikan reaksi positif pada uji Mayer dan Bouchardat, uji Salkowski, serta uji menggunakan akuades dan FeCl3, yang masing-masing mengindikasikan adanya senyawa alkaloid, terpenoid, saponin, dan tanin. Sebaliknya, uji flavonoid dan steroid tidak menunjukkan perubahan warna. Temuan ini menunjukkan bahwa tangkai Capsicum chinense berpotensi sebagai sumber senyawa bioaktif alami yang dapat dikembangkan lebih lanjut.
