Abstract

Coffee (Coffea sp.) is one of the leading commodities in the Indonesian plantation sector. The low productivity of coffee plants can be caused by several factors, one of which is the loss caused by the Coffee Fruit Borer (CFB) Hypothenemus hampei Ferr (Coleoptera: Scolytidae). This research aims to study the flowering phenology of coffee plants and the influence of different plant varieties on the phenology of the CFB. The research was conducted using an exploratory survey method and laboratory analysis. Based on the results, the phenology of H. hampei in each phase has different characteristics, and it was found that there is overlap in the phenology phases of coffee fruit, which causes the life cycle of H. hampei to remain uninterrupted throughout the year. The highest population of H. hampei was found in the BGN 371 compared to the BP cultivar.

Abstract

Bahan organik merupakan salah satu upaya pengelolaan lahan akibat kegiatan pembakaran sisa pascapanen tebu. Bagian tumbuhan yang dapat dijadikan sebagai bahan organik dapat berasal dari serasah daun dan ampas tebu. Salah satu manfaat pemberian bahan organik ialah sebagai sumber energi terhadap fauna tanah, khususnya Collembola. Collembola merupakan organisme yang memiliki habitat di tanah dan berperan penting sebagai perombak bahan organik. Keberadaannya dipengaruhi oleh ketersediaan bahan organik yang ada di suatu lahan, sehingga populasinya akan berbeda-beda. Penelitian ini menguji pengaruh pemberian bahan organik serasah daun tebu dan ampas tebu terhadap kelimpahan Collembola yang ada di lahan. Kegiatan penelitian berlokasi di Badan Standardisasi Instrumen Pertanian Tanaman Pemanis dan Serat (BSIP TAS) yang berada di Kecamatan Karangploso, Kabupaten Malang, Jawa Timur. Penelitian ini menggunakan Rancangan Acak Lengkap (RAL) dengan 3 perlakuan yang terdiri dari masing-masing lahan kontrol (P0), lahan serasah (P1), dan lahan serasah + ampas tebu (P2) dengan 6 ulangan pada setiap perlakuan.  Collembola yang ditemukan pada lahan tebu berjumlah 2.247 individu yang terdiri dari 2 ordo (Poduromorpha dan Entomobryiomorpha), 4 famili (Neanuridae, Entomobryidae, Isotomidae, dan Paronellidae), dan 13 morfospesies. Perbedaan jenis serasah dan bobot memberikan pengaruh terhadap kelimpahan Collembola yang didapatkan di lahan tebu.

Abstract

The Integrated Pest Management (IPM) program was implemented by the government from 1989-1998 through Integrated Pest Management Farmer Field School (IPM-FFS) activities. However, not all regions received this socialization. The uneven socialization activities regarding IPM have resulted in not all farmers having good knowledge about IPM and not all attitudes and actions taken by farmers are in accordance with IPM. Therefore it is necessary to study the evaluation of the level of success of the IPM program that has been implemented. The research was conducted in Purwoasri Village and Langlang Village by interviewing 20 farmers from each village with a questionnaire containing farmer characteristics, farming characteristics, knowledge, attitudes and actions of farmers in IPM. The data obtained was analyzed descriptively by simplifying the data to make it easier to interpret. The results of the research show that the IPM program in Purwoasri Village has been quite successful because IPM farmers are better than nonIPM farmers in terms of farming characteristics, knowledge, attitudes and actions in IPM.

Abstract

This research aimed to determine effect of applying sugarcane litter on the abundance of Collembola species in sugarcane fields using the IPM and conventional systems. This research was conducted from August to January 2021 in sugarcane plantation at sweetener and fiber crop research center (BALITTAS), Karangploso, Malang. Data were analyzed using the formula of diversity index, evenness and dominance and further analyzed with the T test. The results showed there were 5 families of Collembola found in IPM field namely Brachystomellidae, Neanuridae, Sminthuridae, Isotomidae and Entomobrydae. On conventional field, there was no family Neanuridae. Application of litter and intercropping on IPM field increased population of Collembola, while in conventional field, the Collembola population was lower. Application of sugarcane litter increased the levels of organic matter and population Collembola in IPM sugarcane field

Abstract

Humidity at a low level reduces the growth and development of borer pests. On the contrary, coffee plants under shaded conditions grow and develop under higher humidity and lower temperatures, causing the risk of X. compactus. This research aimed to evaluate differences in twig borer attack intensity and their relationship with environmental and management factors. From August to December 2023, research was done in twelve coffee plantations in UB Forest, Dampit, Bangelan, and Ngantang. Direct observations such as infestation intensity, temperature, relative humidity, canopy cover, and the diversity and abundance of weeds and shade trees, were done. We also recorded the pruning, pesticide use, and fertilizer application. The relationships between infestation intensity and habitat management variables were analyzed using general linear models. We concluded that the twig borer infestation intensity varied widely among plantations, with the highest levels recorded in Ngantang. Temperature, canopy cover, species diversity, and weed abundance did not significantly influence infestation levels. Nevertheless, relative humidity presented a significant positive correlation with infestation intensity. Moreover, among the observed management practices, only pruning intensity significantly reduced twig borer infestation, while pesticide application and fertilization had no significant effect.
