Abstract

Diuron herbicide has been used in the pineapple plantation in Lampung, Indonesia, for more than 35 years. It has been realized that the use of herbicides with the same mode of action intensively can speed up the evolution of resistant weeds over a long period of time. This study aimed to determine whether Dactyloctenium aegyptium from pineapple plantation has evolved resistance to diuron and to examine whether the resistance correlates with the weed physiological activities. The study was conducted at the University of Lampung, from September 2018 to March 2019. The study consisted of two stages, i.e. Stage 1: Weed resistance test and Stage 2: Physiological activity test on resistant weed. The study used a split-plot design. The main plot was the origins of weeds (exposed and unexposed to diuron) and thhe supplots was the diuron dose. The result showed that D. aegyptium exposed has high-level resistance to diuron. The physiological activities of D. aegyptium which has a high level of diuron resistance exhibited higher carbon assimilation, stomatal conductance, and transpiration rates than the sensitive D. aegyptium.

Abstract

Identifikasi Gulma Di Perkebunan Kelapa Sawit Rakyat Tanaman Belum Menghasilkan. Tumbuhnya gulma di perkebunan kelapa sawit dapat menurunkan produktivitas kelapa sawit. Gulma bersaing dengan tanaman kelapa sawit dalam memperebutkan sarana tumbuh. Pengendalian gulma harus dilakukan berdasarkan rekomendasi yang tepat sesuai dengan gulma sasaran. Penelitian ini bertujuan untuk mengidentifikasi jenis-jenis gulma yang ditemukan di kebun kelapa sawit tanaman belum menghasilkan. Penelitian dilakukan pada bulan Juni tahun 2022, di kebun kelapa sawit rakyat, Desa Karang Anyar, Kabupaten Lampung Selatan. Penelitian menggunakan metode deskriptif secara purposive sampling pada piringan tanaman kelapa sawit. Hasil identifikasi gulma diperoleh 4 famili yang terdiri dari 10 spesies yaitu Asystasia gangetica, Praxelis clematidea, Mikania micrantha, Synedrella nodiflora, Borreria alata, Axonopus compressus, Paspalum conjugatum, Cyperus iria, dan Cyperus esculentus. Namun, jumlah gulma yang paling banyak ditemukan yaitu A. gangetica.

Abstract

Salah satu faktor yang perlu diperhatikan dalam meningkatkan produksi tanaman kopi adalah pemeliharaan tanaman khususnya pengendalian gulma. Adanya gulma pada tanaman perkebunan dapat menimbulkan kerugian dalam berbagai aspek seperti penurunan hasil panen akibat persaingan unsur hara, air dan sinar matahari. Inventarisasi gulma dilakukan untuk mengetahui gulma penting di lapangan sehingga dapat menentukan pengendalian gulma. Penelitian ini bertujuan untuk mengetahui jenis gulma yang terdapat pada perkebunan kopi rakyat. Penelitian ini dilakukan pada bulan Juni tahun 2023, di kebun kopi rakyat Desa Tugusari, Sumber Jaya, Lampung Barat pada ketinggian 750 mdpl. Pengambilan sampel dilakukan dengan metode kuadran 1 m x 1 m secara purposive sampling pada piringan tanaman kopi sebanyak 4 ulangan. Pengambilan data dilakukan dengan mengidentifikasi jenis gulma dan jumlahnya disetiap kuadran. Hasil inventarisasi gulma diperoleh 7 Family yang terdiri dari 10 Species yaitu: Setaria plicata, Eleusin indica, Drymaria cordata, Asystasia gangetica, Borreria alata, Erechtites valerianifolia, Cosmos caudatus, Ageratum conyzoides, Cuphea balsamona  dan Lindernia crustacea. Family dengan Species gulma yang banyak ditemukan adalah Asteraceae sedangkan jumlah gulma yang paling banyak ditemukan yaitu Drymaria cordata.

Abstract

Weeds are highly undesirable plants in plantation areas, including robusta coffee plants. This is as a result of the presence of weeds that might minimise the productivity of robusta coffee plants. Currently, various types of weeds found in robusta coffee plants are known. This study aimed to enumerate the types of weeds found in robusta coffee plants. The research was conducted in June 2023 in robusta coffee plantations in Wiyono Village, Gedong Tataan, Pesawaran, Lampung Province. The research was conducted by purposive sampling with the plot method. The analysis showed that the composition of weeds in coffee plants consisted of 9 families and 14 species. Ageratum conyzoides appeared to dominate the coffee plants with the highest Summed Dominance Ratio (SDR) value (46.08%).  The weeds diversity index (H') in coffee plants was 0.823 and the dominance index was 0.636576.
