Abstract

Anthracnose is a major disease of chili peppers caused by complex of Colletotrichum species. Intensive application of fungicides is the main choice for control anthracnose. This study aimed to evaluate the sensitivity of Colletotrichum spp. to fungicides and determine the effective concentration to control Colletotrichum spp. This study was conducted from March to July 2024 at the Plant Disease Laboratory, Faculty of Agriculture, Lampung University. Anthracnose pathogens were isolated from Tegineneng District, Pesawaran Regency, Lampung Province. Sensitivity tests were conducted using the recommended concentration with poisoned food techniques. The effective concentration determination test was carried out only on fungicides that showed a resistance response using the poisoned food technique. The fungicides tested were those used by farmers in the location where the samples were taken. The sensitivity test results showed that the fungus Colletotrichum spp. from Tegineneng District was highly resistant to propineb. Colletotrichum spp. from locations 3 and 4 are still sensitive to carbendazim, but from locations 1 and 2 are resistant. Colletotrichum spp. from locations 2, 3, and 4 were still very sensitive to mankozeb, while those from location 1 were moderately resistant. The effective concentration of propineb for locations 1, 3, and 4 was 5x the recommended concentration, and for location 2 was 4x the recommended concentration. The effective concentration of carbendazim for location 1 was 5x the recommended concentration, and for location 2 was 2x the recommended concentration. The effective concentration of mancozeb fungicide at location 1 was 2x the recommended concentration.

Abstract

The sustainability of palm oil agribusiness was a strategic issue that connected economic, social, and environmental aspects in its management. Plantation practices and the palm oil industry contributed significantly to national economic growth and farmer welfare, but in reality, this activity was often associated with deforestation, land degradation, and social conflict. The importance of integrating various aspects of sustainability with agribusiness as a system from farmer perceptions produced priority elements that needed to be prioritized. The purpose of this study was to analyze the determinants of sustainable palm oil agribusiness development. This study was designed using a quantitative method with a survey approach. The sampling technique used proportionate stratified random sampling with a total of 249 smallholder palm oil farmers as respondents. Data processing was carried out using the Partial Least Square (PLS) analysis tool approach. The results of the study showed that the evaluation of modeling findings highlighted a significant influence of farmer rationality on the performance of the agribusiness system and sustainable palm oil agribusiness, as well as a significant influence of the performance of the palm oil agribusiness system on sustainable palm oil agribusiness. Meanwhile, in reality, the test results showed that farmer characteristics did not have a significant influence on any variable. Furthermore, the level of sustainability of palm oil agribusiness was perceived by farmers as more important in order from the social, environmental, technological, and economic dimensions. There was a need for cooperation and support from various parties to achieve and improve the sustainability of palm oil agribusiness, both from the fulfillment of input, production, handling of results, marketing, and supporting services to ensure its sustainability.

Abstract

Tantangan utama dalam budidaya porang adalah meningkatkan kemampuan adaptasi tanaman terhadap naungan, sehingga porang dapat tumbuh dengan baik di bawah kanopi pohon perkebunan. Percobaan ini bertujuan untuk mengkaji pertumbuhan siklus hidup pertama tanaman porang yang berasal dari ukuran bulbil yang berbeda pada tanaman sela di antara pohon karet. Percobaan ini dilaksanakan di kebun karet rakyat yang telah berumur 20 tahun, pada bulan Agustus 2021 - Januari 2022, di Desa Lubuk Batang Kabupaten Ogan Komering Ulu Provinsi Sumatera Selatan. Penelitian ini menggunakan Rancangan Spilt-Split Plot dengan 3 faktor. Petak utama terdiri atas perlakuan naungan yaitu tanpa naungan (N0) dan ditanam di antara pohon karet (N1), dan anak petak  yang terdiri dari perlakuan berat bulbil yaitu bulbil  2 g - 3,9 g (B1), bulbil 4 g - 5,9 g (B2), dan bulbil 10 g -15,9 g (B3); anak-anak petak terdiri atas  morfologi bulbil yaitu tanpa turberkel (D0) dan tuberkel menonjol (D1). Hasil percobaan menunjukkan porang yang ditanam di antara tanaman karet lebih cepat muncul tunas dan mempercepat pecah selubung pertiole 33 HST dan 43,94 HST. Selain itu, tuberkel yang menonjol juga mempersingkat waktu kemunculan tunas selama 45,52 hari. Selanjutnya berat bulbil yang lebih tinggi yakni 10 g – 15,9 g  juga memengaruhi morfologi tanaman porang di antara panjang midrib 14,17 cm, lebar anak daun 5,61 cm,  serta luas daun 212,81 cm. Naungan menjaga kelembapan substrat namun sedikit memperlambat kemunculan tunas dan membuat tunas lebih pendek, namun memperpanjang tangkai daun, meningkatkan luas daun, serta mengurangi ketebalan daun. Selain itu, semakin besar bobot bulbil, semakin cepat pertumbuhan tunas dan tanaman porang. Kondisi bulbil dengan tuberkel menonjol mempercepat kemunculan tunas di atas permukaan tanah dibandingkan dengan bulbil yang masih dalam kondisi tanpa turberkel.
