The Village

Sampali Village is an agricultural area that is very suitable for banana planting. Various types of bananas found in the village include Barangan, Kepok, Molen, Raja and banana Nangka . Banana shoots from harvested mother plants are used for development in new areas. Banana seedlings from the suckers appear healthy, but often these suckers die after 1-2 months of planting in new areas. This is because these bananas have been infected with fungal pathogen wilt caused by Fusarium oxysporm f. sp cubense and Ralstonia syzygii subsp. celebesensis causes of blood diseases. Both of these pathogens are the main cause of the low quality of banana seeds. The use of low-quality banana seedlings (sapling sources), high pest and disease attacks are the factors causing the reduced amount of banana planting land which results in low banana production in Sampali Village, Percut Sei Tuan District, Deli Serdang Regency. Banana farmer groups in the village of Sampali have never used and planted banana seedlings that were propagated by tissue culture. The objectives of the activity were: 1. Socialization and practice of propagation of banana seedlings from sucker . Mycorrhizal inoculant application when planting seedlings in a polybag. To increase the knowledge of farmer group members and also the  students of Agricukture Faculty,Universitas Medan Area the learning of banana propagation techniques is carried out in vitro at the Balai Benih Induk Hortikultura, Gedung Johor Medan . The method used to solve the above problems is the provision of material, the practice of making banana seedlings through the propagation of tillers and a visit to the Balai Benih Induk Hortikultura, Gedung Johor Medan. At the end of the activity, an increase in the knowledge and skills of participants in providing quality banana seeds is the source of banana propagation in the village Sampali

Banyuwangi Regency is one of the agricultural centers in East Java province and Indonesia. Mostly,Banyuwangi people work as farmers due to the fertil soil and wide amount of agricultural land in Banyuwangi . Thelarge number of people who work as farmers initiating the formation of farmer groups. One of the farmer groups in theSrono sub-district of Banyuwangi is the "Tan Selo 1" farmers group located in the village of Sukomaju and the "TanSelo 2" farmers group in Sukonatar village. The normal average price of one banana bunch in Banyuwangi is between50-60 thousand depending on the type and quality of bananas. Problems arise when the quantity of bananas in the marketarose, the price of 1 bunch of bananas decreases dramatically. The price of 1 bunch which is usually set at 50-60thousand drops drastically to only 20-30 thousand. This is certainly a problem for farmers in the Tan Selo group. The lackof knowledge of Tan Selo farmers about alternative variants of processed banana based products and the lack ofknowledge of the marketing strategies make it hard for the Tan Selo farmers to increase the economic value of bananaswhich have been used as an alternative income for farmers. Therefore, the solutions offered to overcome the problems offarmers include: equipping and improving farmers' knowledge about the variety of processed banana-based foods andtheir marketing strategies, conducting training to make variations on banana-based foods, conducting training oneffective marketing strategies. Overall, a series of community service programs were carried out perfectly as it expected.The percentage of participants' understanding in choosing high quality bananas is 85%, the percentage of participants’ability in processing banana-based foods is 86%, and percentage of participants who successfully sell processed foodproducts by utilizing online shopping sites is 70%

The community empowerment is an effort to provide power or empowerment to the community. According to one expert in which he defines community empowerment, namely as the community's ability to develop and be interrelated so that it has the aim of finding new innovations in a community development. (Mardikanto, 2014). The community Empowerment to be precise in the field of agriculture and several Farmer Groups in Tegal Kunir Lor Village is one of the places that becomes objects to improve the quality of agricultural products. This research uses descriptive study and uses qualitative research methods. Based on the research results, empowerment and development needed to be increased towards planting and farmer motivation. The obstacles faced need to be conquered with the problem of not optimal irrigation or irrigation channels to the rice fields. The paddy fields and irrigation infrastructure and agricultural tools are not yet complete. So, it has not made the agriculture managed by the Farmer Group not able to optimize the paddy fields. Implementation of community spirit has not been optimal regarding several issues of awareness that had not been overcome. Enthusiasm of the community has not fully volunteered to enter the Farmer profession in the village of Tegal Kunir Lor so that only a few people, especially the elderly, are doing rice planting in the fields. Village Government, BPP Agricultural Extension Agency, Village Office Staff need to go counseling to encourage residents around the village. This effort is made to create a resilient agriculture that requires quality human resources and make a successor for future progress through agricultural extension activities with an approach farmer groups that support agriculture-based agribusiness system.

Sari Perbanyakan tanaman stroberi secara konvensional dilakukan dengan menggunakan stolon, tetapi kurang efektif serta kualitas bibit yang dihasilkan kurang baik akibat adanya akumulasi penyakit. Budidaya stroberi memerlukan adanya perbanyakan bibit secara massal, tetapi tidak mengubah kualitasnya. Multiplikasi in vitro menjadi solusi untuk penyediaan bibit berkualitas dalam jumlah besar. Upaya untuk mendapatkan tunas in vitro dalam jumlah banyak yakni perlu adanya penambahan zat pengatur tumbuh golongan sitokinin seperti Benzylaminopurine (BAP) atau Thidiazuron (TDZ). Tujuan penelitian ini adalah mengetahui dan menetapkan jenis serta konsentrasi sitokinin dengan hasil terbaik dalam multiplikasi stroberi kultivar Tochiotome. Percobaan dilaksanakan di Laboratorium Kultur Jaringan Tanaman, Teknologi Benih, Fakultas Pertanian, Universitas Padjadjaran. Penelitian menggunakan Rancangan Acak Lengkap yang terdiri dari tujuh perlakuan yang diulang lima kali, yaitu: Kontrol (tanpa sitokinin); BAP (0,25 ppm; 0,50 ppm; 0,75 ppm), dan TDZ (0,25 ppm; 0,50 ppm; 0,75 ppm). Hasil dari percobaan menunjukkan bahwa penambahan sitokinin tidak berpengaruh nyata terhadap jumlah tunas dan bobot segar planlet. Media perlakuan kontrol dapat menghasilkan jumlah akar lebih banyak dibandingkan dengan media ditambah sitokinin. Penambahan BAP 0,50 ppm  berpengaruh positif terhadap jumlah daun dan dapat menghasilkan runner secara in vitro. Pemberian BAP 0,50 ppm cenderung dapat meningkatkan dan mempercepat produksi bibit tanaman stroberi kultivar Tochiotome.Kata Kunci: Benzylaminopurine (BAP), Thidiazuron (TDZ), Stroberi, Kultur Jaringan AbstractStolon is used for conventional propagation of strawberry, but it is less effective and the quality of the seeds is not good due to the accumulation of disease. In vitro multiplication becomes a solution for the supply of quality seeds in a fast time. The addition of growth regulator cytokinin, such as Benzylaminopurine (BAP) or Thidiazuron (TDZ) can produced the large number of shoot. The objective of this study was to obtain the best type and concentration of cytokinin in the multiplication of strawberry ‘Tochiotome’. The study was conducted at the Plant Tissue Culture Laboratory, Seed Technology, Faculty of Agriculture, Universitas Padjadjaran. This study used a Completely Randomized Design (CRD) with seven treatments and five replications, that were: Control (without cytokinin); BAP (0.25 ppm; 0.50 ppm; 0.75 ppm), and TDZ (0.25 ppm; 0.50 ppm; 0.75 ppm). The results indicated that addition of cytokinin did not affected increasing number of shoots and fresh weightof plantlets. Control media can produce larger number of roots than those containing PGRs, this might be due to the endogenous auxin concentrations found in strawberry plants. Also, cytokinin inhibited root formations process. Plants treated with BAP 0.50 ppm increased for the number of leaves and produced runners in vitro. This study showed application of BAP with 0.50 ppm increased and accelerated the production of strawberry ‘Tochiotome’ seedlings.Keywords: Benzylaminopurine (BAP), Thidiazuron (TDZ), Strawberry, Tissue Culture

This exploratory qualitative study examined consumers’ perceived barriers and benefits of plant food (fruits, vegetables, grains, legumes, nuts, seeds) consumption and views on the promotion of these foods. Ten focus groups were conducted in Melbourne, Australia. Groups consisted of employees of various workplaces, community group members, university students, and inner-city residents. Health-related benefits predominated, particularly relating to the properties of plant foods (e.g., vitamins). Taste, variety, versatility, and environmental benefits were also considered important. The main barriers to eating plant foods were lack of knowledge and skills and length of preparation time. The poor quality of plant foods was also an issue for consumers. Awareness of the promotion of plant foods was generally high. Participants noted that promotions require a stronger practical emphasis with a focus on quick, easy-to-prepare foods and meals. These findings provide insight into effective ways to promote a higher consumption of plant foods.

AbstractThe legalization of Cannabis sativa L. for recreational and medical purposes has been gaining global momentum, leading to a rise in interest in Cannabis tissue culture as growers look for large-scale solutions to germplasm storage and clean plant propagation. Mother plants used in commercial propagation are susceptible to insect pests and disease and require considerable space. While micropropagation can produce disease free starting material in less space, current published in vitro micropropagation methods are not robust and few report high multiplication rates. Further, these micropropagation methods rely on photoperiod-sensitive plants which can be maintained in a perpetual vegetative state. Current methods are not adaptable to long-term tissue culture of day-neutral cultivars, which cannot be maintained in perpetual vegetative growth. In this study, we chose to develop a micropropagation system which uses C. sativa inflorescences as starting materials. This study used two cannabis cultivars, two plant growth regulators (PGR; 6-benzylaminopurine and meta-topolin) at different concentrations, and two different numbers of florets. Here we show that floral reversion occurs from meristematic tissue in C. sativa florets and that it can be used to enhance multiplication rates compared to existing in vitro methods. Floret number was shown to have a significant impact on percent reversion, with pairs of florets reverting more frequently and producing healthier explants than single florets, while cultivar and PGR had no significant effect on percent reversion. Compared with our previously published nodal culture studies, the current floral reversion method produced up to eight times more explants per tissue culture cycle. Floral reversion provides a foundation for effective inflorescence-based micropropagation systems in C. sativa.

Loa Village is one of the villages located in Paseh District, Majalaya, Bandung Regency. Loa Village has potential to be developed, in the field of animal husbandry. Many of the resident raising the chicken and duck in groups, but still use the traditional method, which is naturally hatching eggs by the hen so that it is difficult to get Kampong chicken seeds. With the village profile as above, we are challenged to provide the knowledge and techniques of raising Kampong chickens to Loa Village public, especially to farmer group members, through the virtual KKN-PPMD Padjadjaran University. The purpose of this activity is to increase the knowledge and skills of breeders in raising chickens, hatching eggs, composing the rations, processing chicken products and increasing the production of day old chicks. Apparently, the enthusiasm of the participants to gain knowledge and skills in raising Kampong chicken was quite high. Knowledge of the participants regarding the management of chickens, the preparation of rations are still lacking, but the enthusiasm of farmers to learn all the knowledge about raising Kampong chickens is very good, so that this activity can increase knowledge about how to hatch eggs and skills to operate the incubator and  have a great passion for the business of  Kampong chickens. Abstrak Desa Loa merupakan salah satu desa yang berada di Kecamatan Paseh, Majalaya Kabupaten Bandung. Desa Loa memiliki potensi yang harus dikembangkan, salah satunya yaitu potensi di bidang peternakan. Banyak dari penduduknya yang merupakan kelompok peternak ayam dan entok, tetapi masih menggunakan cara trasional yaitu menetaskan telur secara alami oleh induk sehingga sulit mendapatkan bibit ayam kampung. Melihat profil desa seperti di atas, maka kami tertantang untuk memberikan pengetahuan tehnik beternak ayam kampung kepada para anggota kelompok tani melalui Kegiatan KKN-PPMD virtual universitas Padjadjaran kepada masyarakat Desa Loa khususnya kepada kelompok peternak. Tujuan dari kegiatan ini adalah untuk meningkatkan pengetahuan dan keterampilan peternak dalam budidaya beternak ayam, menetaskan telur, menyusun ransum, dan pengolahan hasil ternak ayam serta meningkatkan produksi anak ayam untuk bibit. Dari kegiatan ini antusiasme peserta untuk memperoleh pengetahuan dan keterampilan usaha budidaya beternak aym lokal cukup tinggi. Wawasan peserta mengenai tatalaksana pemeliharaan ayam, serta penyusunan ransum masih sangat kurang, tetapi animo peternak sangat baik untuk belajar semua pengetahuan tentang budidaya beternak ayam lokal, sehingga kegiatan ini dapat meningkatkan pengetahuan mengenai cara-cara menetaskan telur dan keterampilan mengoperasikan cara menetaskan telur dengan mesin tetas dan semangat untuk usaha beternak ayam kampung.

In vitro culture of immature inflorescences of F1 hybrid plants originating from the cross between the common wheat cultivar Roazon and two inbred lines of rye was carried out with 2,4-dichlorophenoxyacetic acid in the medium. After 3 or 8 weeks of culture as undifferentiated callus, 62 plants could be regenerated. Of these, 47 reached the adult stage; 46 of which were analysed for chromosome counts and chromosome pairing. For 44 of these, chromosome counts showed high stability and phenotypes were similar to those of the mother plants. In vitro culture of immature inflorescences could therefore be considered as a possible vegetative multiplication method to obtain numerous copies from one individual. The three other plants exhibited variations in phenotype and chromosome number: one was an amphiploid, and a chromosome was lost in each of the other two. All meristematic cells and pollen mother cells were involved in these numerical changes for each plant. The amphiploid plant (2n = 56) was nonchimeric and all the spikes were highly self-fertile. It could be an efficient method for chromosome doubling. This underscores the usefulness of inflorescence tissue culture for overcoming the sterility barrier in interspecific hybrids.Key words: wheat × rye hybrids, tissue culture, amphiploidization, aneuploidy, meiotic behaviour.
