Pembangunan dan pengembangan kualitas masyarakat petani dalam melaksanakan usahatani merupakan salah satu aspek yang mendukung terciptanya peningkatan produksi dan produktivitas pertanian, sehingga keuntungan dapat ditingkatkan. Pembangunan pertanian khususnya tanaman hortikultura yang telah dilaksanakan, telah memberikan kontribusi yang positif terhadap perkembangan ekonomi. Semakin jelas dan nyata bahwa sistem perekonomian, semakin dipengaruhi oleh sektor pertanian. Sektor ini mempunyai dampak dalam kelangsungan pendapatan petani suatu daerah. Budidaya tanaman sayuran di Indonesia umumnya dilakukan dengan pola tanam monokultur dan polikultur. Monokultur adalah sisitem budi daya pada suatu areal lahan yang ditanami dengan satu jenis tanaman saja. Sedangkan polikultur merupakan sistem budi daya tanaman pada satu areal lahan yang sama dalam satu tahun ditanami dengan beberapa jenis tanaman, baik yang ditanam dalam waktu yang bersamaan atau waktu yang sedikit berbeda. Perkembangan hama dan penyakit cenderung lebih mudah terjadi pada pola tanam monokultur karena sumber makanan bagi hama dan patogen selalu tersedia. Sebaliknya pada pola tanam polikultur yang diikuti dengan pola rotasi tanaman dapat memutus siklus hidup hama dan penyakit. Rotasi tanaman memiliki banyak keunggulan. Pada beberapa sistem budidaya tanaman organik, rotasi tanaman sangat direkomendasikan. Beberapa keunggulan rotasi tanaman adalah mampu mengurangi intensitas serangan hama atau penyakit, meningkatkan kesuburan tanah, serta rotasi tanaman sangat direkomendasikan. Beberapa keunggulan rotasi tanaman adalah mampu mengurangi intensitas serangan hama atau penyakit, meningkatkan kesuburan tanah, serta mampu membentuk ekosistem mikro yang stabil. Selain itu, di dalam dunia agribisnis pada beberapa jenis komoditas terutama jenis sayuran mampu memenuhi permintaan pasar yang diinginkan.
The research was aimed to formulation combination of composite flour as partly substitution of wheat flour from blend of wheat flour, sweet potato flour and taro flour. This research used a Completely Randomized Design (CRD) Non Factorial, with different level of substitution in percents, i.e :T1 = wheat flour (100%), T2 = wheat flour (75%) : sweet potato flour (25%), T3 = wheat flour (50%) : sweet potato flour (50%), T4 = wheat flour (25%) : sweet potato flour (75%), T5 = wheat flour (75%) : taro flour (25%), T6 = wheat flour (50%) : taro flour (50%), T7 = wheat flour (25%) : taro flour (75%). The parameters analysed were moisture content, ash content, protein content, fat content,carbohydrate content and hedonic value of colour, aroma, flavour and texture. The results showed were significant differences (p<0.5) difference formulation combination of composite flour with different level of substitution. The proximate composition showed that wheat flour had higher protein content (9.46%) and lower carbohydrate content (87.77%), while sweet potato flour had protein content(3.96%) and carbohydrate content (92.92%); taro flour had protein (5.62%) and carbohydrate content (92.83%). The sensory analysis of cake showed significant differences between 100% wheat flour and formulation combination of composite flour samples. It was concluded that formulation composite flour T4 into wheat flour gave the cake with the best overall quality acceptabily.
Andung sari 1 coffee seeds made in Suka Mbayak Village have a large fruit production, but not too high, do not have many wild shoots, are resistant to pests and stems so that farmers are more interested in planting Arabica coffee seeds (Coffea arabica) Andung sari varieties 1. The research method in the research area was determined purposively or deliberately based on the primary data of 20 families of Andung sari 1 arabica coffee farmers, with the characteristics of the respondents described by gender, education, age and occupation. Based on the results of respondents in the field according to gender, the male andung sari coffee farmers were the most respondents (90.1%). Based on the latest education, the most respondents were junior high school and high school students (38.8%). According to respondents, the most age groups were respondents aged 31 - 40 years (65.6%) and while based on job respondents the most respondents were coffee farmers (60.5%). Based on the results of the above research, it can be concluded that cultural, social, personal and psychological factors simultaneously have a positive and significant effect on the decision to purchase Arabica coffee seedlings of Andung Sari 1 variety, this can be seen in the value of F count> F table (18,144> 2,494 ) and the significant value is smaller than the significant level 0.05 (0.000 <0.05), then the fifth hypothesis is accepted, meaning that it simultaneously has a positive influence on the decision to purchase Andung Sari 1 coffee seedlings.
Community service is carried out as part of the implementation of the Tri Dharma of Higher Education which aims to assist the community in increasing knowledge and skills in the field of making brown sugar that utilizes the sap of palm oil stems. Oil palm stem sap can be processed into brown sugar which is an alternative for processing palm oil waste in Sei Musam Village, Sei Batang Serangan District, Langkat Regency. The method of implementing this community service activity is in the form of assistance to brown sugar producers in the form of technology transfer, management, and equipment support. Assistance activities carried out for 2 (two) days. The result of the mentoring activities is an increase in palm sap processing skills, and an increased understanding of business management, especially in financial governance with simple bookkeeping. Assistance to brown sugar artisans needs to be done considering the quality of brown sugar produced so far is still low and the shape of the brown sugar produced is not uniform. The assistance team provided equipment in the form of a brown sugar molding tool to produce a uniform brown sugar mold so that when it is packaged it looks neat for marketing. From the community service activities that have been carried out, it shows that the craftsmen are able and successful in making brown sugar uniform shapes and are able to calculate the cost of producing brown sugar from palm oil stem sap.
The study was done to see how chrysanthemum flower products developed from the way chrysanthemum flower production and marketing was developed. To know internal and external strategies and swot analysis support the development of chrysanthemum products in Karo regency. Adhesive control of research areas. The sample is a goatherd, a farm group, a chief of the service who endear the farm service, a goat merchant, and an entire agency of Suka village. Data retrieval through interview, documentation and observation questionnaire. The result of the study are internal factor : Stregth (natural resourches, human resourches, security strive) Weakness (limited markets, limited land, lack of government support), External factor : Opportunities (regional auotnomy, chrysanthemum flower derivatives, markets that are open locally and abroad, opening up new agrotourism) Threats (pests and disease, competitor flowers, chrysanthemum price fluctuations) and strategy of a swot matrix, which is to improve the natural resourches quality through training and expand its chrysanthemum farm effort, increase productivity and the quality of chrysanthemum flower and their markets, increase productivity and the quality of chrysanthemum flower to be able to compete with foreign market, open up new agrotourism with the support of natural resourches and regional autonomy.
