Abstract

Beras termasuk komoditas pangan masyarakat Indonesia selain jagung dan sorgum. Hama kumbang bubuk termasuk penyebab kerusakan beras di penyimpanan. Kerentanan beras dipengaruhi oleh jumlah F1 dan median waktu perkembangan hama kumbang bubuk. Penelitian bertujuan menentukan kerentanan beras putih terhadap infestasi hama kumbang bubuk beras selama penyimpanan. Jenis beras putih yang digunakan terdiri dari berbagai varietas padi yaitu Ciherang, Mekongga, Cigeulis, Inpari 30, Inpari 32, 42, 44, dan Inpari Sidenuk. Pengujian kerentanan menggunakan metode tanpa uji pilihan. Variabel pengamatan meliputi jumlah F1, median waktu perkembangan, indeks kerentanan, dan susut berat beras. Hasil penelitian menunjukkan bahwa kerentanan beras tersebut ditentukan oleh jumlah F1, median waktu perkembangan, dan persentase susut berat. Beras dari Varietas Ciherang dan Cieugelis tergolong moderat sampai rentan, sedangkan dari Varietas Inpari 30, 32, 42, 44, Inpari Sidenuk, dan Mekongga tergolong moderat terhadap infestasi S. oryzae selama penyimpanan.

Abstract

Storage of cereal is a section of the stage post-harvest and helpful for maintaining food availability against crop failures and natural disasters. The losses yield commodity cereal happened at the stage storage caused by Rhyzopertha dominica. This study aimed to determine the comparison population R. dominica and damage to rice and sorghum based on the storage period. The types of cereals used are rice and sorghum. The research was arranged in a completely randomized design (CRD) with the treatment of storage periods for rice and sorghum consisting of five levels is storage for 40, 60, 80, 100, and 120 days. Observation parameters included population R. dominica and damage as well increased moisture content of rice and sorghum. Data obtained from the observations were analyzed using analysis of variance.  The results showed that the population of R. dominica and damage more happened to sorghum than rice based on the storage period. The storage period of 120 days could increase population R. dominica, damage and moisture content of rice and sorghum. Knowledge of the storage period for rice and sorghum give information so that not to stored rice and sorghum for long time periods

Abstract

Hypothenemus hampei (Ferrari) (Coleoptera: Scolytidae) or Coffee Berry Borer (CBB) is the most destructive major pest that causes quantitative and qualitative losses in Arabica coffee. The research aimed to calculate population, attack H. hampei, coffee yield losses, the measure distribution pattern of H. hampei on various Gayo arabica coffee varieties, and the analyze estimated decrease in the production of coffee based on population and attack H. hampei in Gayo arabica coffee. The location chosen as a place of observation and sampling is a smallholder coffee plantation with variations in elevation. Each area is determined by two points of observation and sampling locations. At each sampling location, 80 ripe or red coffees were taken, 80 dark or yellow coffees, and 80 young or green coffees (24 pieces per four branches per tree). The results showed that the population and attack of CBB pests on Gayo 3 varieties are relatively high compared to Gayo 1 and Gayo 2 varieties. The distribution pattern of CBB on all varieties of Gayo Arabica coffee showed an aggregated distribution based on population and attack. The decrease in arabica coffee production has the potential to occur on a variety Gayo 3.
INTENSITAS SERANGAN DAN POLA SEBARAN HAMA PENGGEREK BUAH KAKAO (Conopomorpha cramerella) DI KABUPATEN ACEH UTARA: ATTACK INTENSITY AND DISPERSION PATTERN OF THE COCOA POD BORER (Conopomorpha cramerella) IN NORTH ACEH DISTRICT Dhean, Tengku; Hendrival, Hendrival

Abstract

Hama penggerek buah kakao (Conopomorpha cramerella) merupakan salah satu hama utama yang dapat menyebabkan kehilangan hasil kakao hingga 80% di Indonesia. Penelitian ini bertujuan untuk mengkaji intensitas serangan dan pola sebaran hama penggerek buah kakao pada perkebunan kakao di Kabupaten Aceh Utara, Provinsi Aceh. Penelitian dilaksanakan pada Januari–Februari 2026 di tiga kecamatan, yaitu Nisam Antara, Matangkuli, dan Tanah Luas, menggunakan metode purposive sampling. Pengamatan dilakukan pada 10% dari total populasi tanaman per petak, dengan 20 buah kakao sebagai sampel per pohon setiap minggu selama empat minggu. Intensitas serangan dihitung berdasarkan skor kategori kerusakan (0–3), sedangkan pola sebaran ditentukan menggunakan nisbah ragam terhadap rata-rata (S²/m), indeks pengerombolan Lloyd (m̅/x̅), serta koefisien Green (Cx). Hasil penelitian menunjukkan bahwa persentase serangan berkisar 10,50–19,50% di Nisam Antara (kategori ringan), 34,75–44,25% di Matangkuli (kategori sedang), dan 50,50–63,50% di Tanah Luas (kategori berat). Intensitas serangan masing-masing berkisar 4,58–9,42%, 19,25–28,02%, dan 29,58–39,67%. Berdasarkan ketiga parameter pola sebaran, hama penggerek buah kakao menunjukkan pola sebaran mengelompok (aggregated) di seluruh lokasi pengamatan. Tingginya intensitas serangan dan pola pengerombolan hama diduga berkaitan erat dengan kondisi kebun yang tidak terawat, kurangnya pemangkasan, serta terbatasnya penerapan pengendalian hayati. Temuan ini menegaskan perlunya strategi pengendalian hama terpadu untuk menekan serangan hama dan meningkatkan produktivitas tanaman kakao.
