No full textInnovation attributes and their linkages to behavioral drivers of farmers’ intention to adopt True Shallot Seed
Full text linkTrue Shallot Seed (TSS) has been promoted as an alternative solution to overcome shallot yield problems in Indonesia. A case study method was employed to assess perceptions of innovation attributes and their linkages to behavioral drivers of farmers’ intention to adopt TSS. Respondents were shallot farmers in Cirebon and Brebes involved in participatory on-farm trials. All innovation attributes, i.e. relative advantage, compatibility, complexity, triability and observability are perceived as positive by farmers. Farmers’ attitudes toward TSS suggest a favorable evaluation of TSS innovation. Concerning subjective norms, farmers believe that researchers/extension workers encourage their behavior to adopt TSS. In terms of behavioral control, farmers perceive the ease of performing TSS adoption. Meanwhile, farmers also indicate a high intention to perform the behavior of adopting TSS. This pre-adoption case study has generated some hypotheses for further detailed examination and test. Those hypotheses address important research needs, such as understanding TSS innovation attributes as perceived by farmers, the antecedents of farmers’ attitudes toward TSS, and the role of farmers’ behavioral preferences toward intentions to adopt TSS. It is recommended to integrate the innovation diffusion theory with the theory of planned behavior as the framework for future adoption studies using survey research method
Analisis Trend Hasil Per Satuan Luas Tanaman Sayuran Tahun 1969-2006 Di Indonesia
Full text link. Adiyoga, W. 2009. Yield Trend Analysis of Vegetable Crops in Indonesia 1969-2006. The study wascarried out in April to June 2008 by utilizing secondary data of annual vegetable production and harvested area that coveredthe period of 1969-2006. Vegetable crops included in this study were kidney bean, bunching onion, shallots, garlic, hotpepper, potato, cabbage, chinese radish, cucumber, chinese cabbage, eggplant, tomato, and carrot. The objective ofthis study was to analyze the temporal trend of vegetable production and yield in Indonesia using yield trend, growthtrend, and yield stability trend analysis. The results indicated that long-term trend analysis of 1969-2006 period did notshow any slowing yield growth for all vegetable crops studied. However, the ten-years periods trend analysis suggeststhe trend of slowing yield growth for kidney bean, shallots, garlic, hot pepper, chinese radish, and chinese cabbage incertain ten-year periods. During the period of 1969-2006, the lowest average annual production growth was shownon garlic (-6.3%), and the highest was on carrot (8.5%). The lowest annual growth in harvested area was shown bygarlic (-7.5%), while the highest was indicated by tomato and carrot (6.6%). The lowest annual yield growth was foundon hot pepper (-2.5%), while the highest was on kidney bean (6.8%). The production growth of shallots, hot pepper,potato, chinese radish, cucumber, chinese cabbage, tomato, and carrot in 1969-2006 has been dominantly harvestedarea-led. Meanwhile, yield growth has been a dominant source of kidney bean, bunching onion, garlic, cabbage, andeggplant production growth. During 1969-2006, absolute yield variability for chinese radish was increasing, while forcucumber and chinese cabbage was decreasing. Furthermore, a decreasing relative yield variability, i.e. more stableyield, was indicated for kidney bean, bunching onion, shallots, garlic, hot pepper, cucumber, chinese cabbage, eggplant,tomato, and carrot. The lowest yield coefficient of variation was shown by chinese cabbage, while the highest wasshown by hot pepper. The effort for increasing bunching onion, garlic, potato, cabbage, chinese cabbage, and carrotproduction should be initiated by identifying the causes of harvested area variability that have to be sorted in terms offactors such as relative profitability and other constraints. Meanwhile, since a greater contribution of yield variabilityto production variability was identified, the effort for increasing kidney bean, shallots, hot pepper, chinese radish, cucumber, eggplant, and tomato production suggests the need for identifying the causes of yield variability in termsof research, extension, and policy measures. Responding to a slowing yield trend for some vegetable crops, breedingresearch activities that are increasing yield frontier-oriented still need to be prioritized. Moreover, breeding researchactivities that are generating reduction in yield variability, such as disease and pest resistance and environmentalstressedtolerance should also be emphasized
Research and extension linkages in technology generation and transfer for food and horticultural crops in West Java, Indonesia
No full textThe primary purpose of this study was to examine the linkages between research and extension agencies in generating and transferring technology for food and horticultural subsectors in West Java, Indonesia.This study used a descriptive-comparative survey method. The two populations included in this study were: (a) researchers from food crops and horticultural research institutes and (b) extension workers (subject matter specialists) for food and horticultural crops in West Java, Indonesia. The samples were randomly selected and the data were collected through a mailed questionnaire. Some statistical procedures and content analysis were used to analyze the data.The findings indicated that the effectiveness of linkage mechanisms, in terms of the intensity of resources/information exchanged was still perceived to be low. This effectiveness was perceived to be mainly influenced by the extent to which a mutual resource exchange occurred between the two agencies.The overall perceptions about the five linkage indicators studied (integration, coordination, availability and relevance of new technology, structural conflict, and operating conflict) were found to be moderate to low. Contextual factors that were mostly perceived as determinants for linkages were internal and external pressures and resources availability. Meanwhile, the extension workers perceived that they faced more limitations regarding the financial resources available and received more frequent pressure from farmers, superiors, colleagues, and national policy makers to establish closer linkages. There was still a tendency that researchers perceived extension workers as less competent and having less capacity to follow through on joint activities that had been agreed upon.More attention should be given to designing policies for encouraging research-extension linkages. Linkage mechanisms should be developed by considering a mutual resource exchange between research and extension agencies. Furthermore, these mechanisms should be developed appropriately on the basis of the institutional and political context in which they would be used.Made available in DSpace on 2011-05-07T12:06:04Z (GMT).

Pemahaman tentang preferensi konsumen sangat penting dalam proses pengambilan keputusan pemangku kepentingan utama, termasuk bagi produsen/petani serta berbagai pihak terkait yang beroperasi di dalam subsektor sayuran. Penelitian ini diarahkan untuk menghimpun informasi menyangkut preferensi konsumen atau optimalisasi utilitas atribut produk untuk komoditas prioritas/unggulan sayuran (kentang, bawang merah, dan cabai merah). Kegiatan penelitian dilaksanakan pada Bulan Juni sampai dengan September 2008 di tiga kota besar konsumen sayuran, yaitu Jakarta (DKI Jaya), Bandung (Jawa Barat), dan Padang (Sumatera Barat). Penelitian survai menggunakan kuesioner terstruktur dilaksanakan untuk mewawancarai 335 responden yang dipilih secara acak di ketiga kota tersebut. Atribut produk yang diamati mencakup atribut eksternal, internal, dan organoleptik. Preferensi konsumen diidentifikasi menggunakan analisis konjoin yaitu salah satu modul dalam program SPSS. Hasil penelitian menunjukkan bahwa konsumen mengekspresikan preferensinya terhadap kentang yang berukuran 6–8 butir/kg, berkulit mulus, dan memiliki jumlah mata sedikit (<10). Konsumen menganggap ukuran umbi kentang merupakan faktor terpenting dalam menilai atau membeli kentang, dan secara berturut-turut diikuti oleh faktor permukaan kulit serta jumlah mata. Sementara itu, bawang merah yang paling disukai konsumen ialah bawang merah dengan diameter umbi 2,5 cm, berwarna kulit merah-ungu tua, dan beraroma tidak menyengat. Urutan kepentingan atribut bawang merah menurut persepsi konsumen secara berturut-turut yaitu warna kulit, ukuran umbi, serta aroma. Sementara itu, konsumen lebih menyukai cabai merah yang besar, kulit berwarna merah terang, dan memiliki kepedasan agak pedas. Dalam konteks atribut produk cabai merah yang digunakan untuk mengukur preferensi, faktor terpenting yang berpengaruh dalam proses pengambilan keputusan yaitu warna kulit, dan secara berturut-turut diikuti oleh faktor jenis cabai serta tingkat kepedasan.ABSTRACT. Adiyoga, W and Nurmalinda 2012. Conjoint Analysis of Consumer Preferences on Potato, Shallots, and Hot Pepper’s Product Attributes. Understanding consumer preferences is important in the context of decision-making of key stakeholders, including producers themselves, as well as development agencies that operate in the vegetable subsector. This study was aimed at collecting information on consumer preference or optimizing the utility of product attributes of vegetable priority crops (potato, shallots, and hot peppers). It was carried out in June-September 2008 in three big vegetable consuming cities, Jakarta (Capital Special-Region of Jakarta), Bandung (West Java), and Padang (West Sumatera). Survey method by using a structured questionnaire was implemented to interview 335 respondents randomly selected in the three cities. Parameters observed were external, internal, and organoleptic attributes. Consumer preferences were identified by using conjoint analysis – a module in Statistical Program for Social Sciences (SPSS). The results showed that consumers express their preference to potato that has some characteristics, such as medium size of tuber (6-8 tubers/kg), smooth-flawless skin, and few numbers of eyes (<10). Tuber size were perceived as the most important factor affecting purchasing decision, and followed by skin and number of eyes. The most preferred shallots was the one that has a diameter of 2.5 cm in size, dark-violet red skin color, and least strong aroma. The rank of shallot’s attributes importance as perceived by consumers were skin color, tuber size, and aroma, consecutively. Meanwhile, consumers prefer hot peppers that has the characteristics of bright-red skin color, big-hot peppers type, and slightly hot. Within the context of measuring preference, the most important hot peppers attribute that influences consumer decision making were skin color, and then followed by hot peppers type, and hotness
Segmentasi Konsumen Kentang, Bawang Merah, dan Cabai Merah Berdasarkan Peubah Sosio-Demografis dan Kepentingan Kriteria Produk
Full text linkPenelitian bertujuan untuk mengidentifikasi segmen-segmen konsumen kentang, bawang merah, dan cabai merah berdasarkan peubah sosio-demografis dan persepsi tentang kepentingan kriteria produk. Penelitian survai dilaksanakan di tiga kota besar konsumen utama sayuran, yaitu Jakarta (DKI Jaya), Bandung (Jawa Barat), dan Padang (Sumatera Barat) pada bulan Juni sampai dengan September 2006. Responden terdiri dari 335 konsumen kentang, bawang merah, dan cabai merah yang dipilih secara acak. Alat analisis yang digunakan ialah statistik deskriptif, tabulasi silang, dan analisis klaster. Hasil penelitian menunjukkan bahwa untuk kentang, dua peubah sosio-demografis (pendidikan dan pengeluaran) dan 11 peubah kriteria produk (kesegaran, rasa, kebersihan, nilai gizi, tidak mengandung residu pestisida, penampakan luar, tidak ada tanda busuk, harga, kemasan, label produk, dan kenyamanan tempat pembelian) berpengaruh nyata terhadap perbedaan karakteristik segmen konsumen kentang. Jumlah segmen konsumen kentang yang dianggap paling sensible (pantas/masuk akal) ialah tiga segmen (segmen 1=120 orang, segmen 2=12 orang, dan segmen 3=203 orang). Berdasarkan komposisi tersebut, pemasar/petani kentang disarankan agar lebih mengarahkan strategi pemasarannya ke segmen 3. Untuk bawang merah, tiga peubah sosio-demografis (pendidikan, pekerjaan, dan pengeluaran) dan 13 peubah kriteria produk (kesegaran, kebersihan, nilai gizi, tidak mengandung residu pestisida, penampakan luar, tidak ada tanda busuk, harga, warna, aroma, label produk, produk lokal, produk impor, dan kenyamanan tempat pembelian) berpengaruh nyata terhadap perbedaan karakteristik segmen konsumen bawang merah. Jumlah segmen konsumen bawang merah yang dianggap paling sensible ialah dua segmen (segmen 1=113 orang dan segmen 2=222 orang). Komposisi anggota klaster tersebut menyarankan kepada pemasar/petani bawang merah agar lebih mengarahkan strategi pemasarannya ke segmen 2. Untuk cabai merah, empat peubah sosio-demografis (pendidikan, pekerjaan, pengeluaran, dan frekuensi memasak sendiri) dan 11 peubah kriteria produk (kesegaran, rasa, kebersihan, nilai gizi, tidak mengandung residu pestisida, penampakan luar, tidak ada tanda busuk, harga, warna, label produk, dan kenyamanan tempat pembelian) berpengaruh nyata terhadap perbedaan karakteristik segmen konsumen cabai merah. Jumlah segmen konsumen cabai merah yang dianggap paling sensible ialah tiga segmen (segmen 1=152 orang, segmen 2=2 orang, dan segmen 3=181 orang). Komposisi anggota klaster tersebut menyarankan kepada pemasar/petani cabai merah agar lebih mengarahkan strategi pemasarannya ke segmen 3 dan 1. Penelitian lebih lanjut perlu mempertimbangkan pencantuman peubah kriteria produk secara lebih terinci dan spesifik.The objective of this study was to identify market or consumer segments of potato, shallots, and hot peppers based on socio-demographic variables and the importance of product criteria. Consumer surveys were carried out in three big cities of vegetable main consumer in Indonesia i.e. Jakarta (DKI Jaya), Bandung (West Java), and Padang (West Sumatera) from June to September 2006. Respondents of these surveys were 335 potato, shallots, and hot peppers consumers who were randomly selected. Descriptive statistics, cross tabulations, and cluster analysis were used for data elaboration. Results show that for potato, two socio-demographic variables (education and expenditures) and 11 product criteria variables (freshness, taste, cleanliness, nutrient value, no pesticide-residue, appearance, no blemishes, price, packing, product label, and convenient purchasing place) were significantly contributing to the separation of the potato clusters. Three clusters are identified as the most sensible subgroup for potato consumer segments i.e. segment 1=120 cases, segment 2=12 cases, and segment 3=203 cases. Based on this composition, potato marketers/farmers were suggested to focus on segment 3 for implementing their marketing mix strategy. For shallots, three socio-demographic variables (education, employment, and expenditures) and 13 product criteria variables (freshness, cleanliness, nutrient value, no pesticide-residue, appearance, no blemishes, price, color, aroma, product label, local product, imported product, and convenient purchasing place) were significantly contributing to the separation of the shallots clusters. Two clusters were identified as the most sensible subgroup for shallots consumer segments i.e. segment 1=113 cases and segment 2=222 cases. Based on this composition, shallots marketers/farmers are suggested to focus on segment 2 for implementing their marketing mix strategy. For hot peppers, four socio-demographic variables (education, employment, expenditures, and self-cooking frequency), and 11 product criteria variables (freshness, taste, cleanliness, nutrient value, no pesticide-residue, appearance, no blemishes, price, color, product label, and convenient purchasing place) were significantly contributing to the separation of the hot peppers clusters. Three clusters were identified as the most sensible subgroup for hot peppers consumer segments i.e. segment 1=152 cases, segment 2=2 cases, and segment 3=181 cases. Based on this composition, hot peppers marketers/farmers were suggested to focus on segment 3 and 1 for implementing their marketing mix strategy. Further study needs to consider involving more detailed and more specific product criteria variables
Seed Systems in the Four Shallot Producing Areas of Java: A Focus Group Discussion
No full textUnderstanding shallot seed systems is crucial for managing crop biodiversity on-farm where it is of both private value to farmers and social significance for future crop improvement and the resilience of the farming system. Focus Group Discussion (FGD) was carried out in Cirebon-West Java, Brebes-Central Java, Bantul-Yogyakarta S.R and Nganjuk-East Java. In Java, FGDs estimate that the share of formal seed sector in the total shallot seed supply rarely exceeds 5%. Hence, the seed supply is heavily relied on the informal seed system in which farmers use their-own strategies, including farmer-saved seeds, farmer seed exchange, and farmer-managed seed production. In the meantime, FGDs indicate that both systems in general are still characterized by low quality seeds, limited clean/healthy seeds, lack of supporting qualified human resources, lack of supporting infra-structure, and low transfer of seed technology. Both systems actually have considerable strengths to be leveraged and weaknesses to be improved. Therefore, FGDs suggest that integrating and recognizing the coexistence of the formal and informal seed systems in the four shallot producing areas in Java should be embraced to optimize the mutual benefits between the two systems

Full text link. Adiyoga, W., T. A. Soetiarso, and M. Ameriana. 2008. Component Interactions in Crop-livestock System in West Java Highland Ecosystem. This study was carried out in West Java highland areas (Lembang – Cibodas and Suntenjaya village, Pangalengan-Pulosari and Margamulya village, and Ciwidey – Lebakmuncang and Panundaan village) from June to October 2004. The objective of this study was to examine the component interactions of crop-livestock system in highland ecosystem. Respondents surveyed were those who grew vegetables and raised livestock simultaneously. Number of respondents selected were as follows: Lembang 40 respondents, Pangalengan 45 respondents, and Ciwidey 44 respondents. The results showed that crop livestock system (CLS) in West Java highland can be classified as diversified mixed farming systems, not integrated, consist of components such as crops and livestock that co-exist rather independently from each other (minimum interactions). In this case the mixing of vegetable crops and dairy-cows primarily serves to minimize risk and not to recycle resources. Nutrient flows tend to be linear, since the activity of resource-recycling is not significant. Minimum interactions between components were also reflected from zero contribution of labor from dairy-cow subsystem to the total labor requirement for vegetable cultivation; 0-25% contribution of manure from dairy-cow subsystem to the total organic fertilizer requirement for vegetable cultivation, and 0-10% contribution of crop wastes or by-products from vegetable farming to the total feed requirement for dairy-cows farming. Regarding resource utilization, there was high competition in labor-use, especially family labor, between vegetable and dairy-cows farming. Positive impacts of CLS perceived to be significant were the use of leys containing grasses and legumes to reduce erosion and use of manure to improve soil structure and fertility. Meanwhile, the negative impacts of CLS, such as pollution; environmental disruption and health hazards from disease and pest chemical control measures were beginning to be perceived as slightly significant and need more attention for finding the problem solution
