Abstract

Cabbage (Brassica oleracea var capitate), broccoli (B. oleraceae L. var italica), carrots, and cauliflower (B. oleracea var botrytis) are the primary vegetable crops grown in Ngablak. The role of chemical fertilizers in crop enhancement cannot be avoided in the production of vegetables. Chemical fertilizers come in a variety of forms, including nitrogenous, phosphate, and potassium fertilizers. Fertilizer use not only boosts crop yield, but also modifies the physical, chemical, and biological aspects of the soil. However, the continual use of chemical fertilizers has led to a loss in soil organic matter (SOM) and a deterioration in the quality of agricultural soil. The excessive use of chemical fertilizers hardens the soil, diminishes soil fertility, pollutes the air, water, and soil, and depletes vital soil nutrients and minerals, consequently posing environmental risks. This research breakthrough is needed to reduce chemical fertilizers. Biochar, a pyrolyzed or anaerobically-grown biomass, could be used. This study examined the effects of biochar on disease suppression and yield in Brassica oleracea plants in rich soils in Magelang, Central Java. The treatment of this study was control, biochar, biochar+compost. The results of this study can be concluded that the maximum wet and dry weight of broccoli and cabbage plants was achieved in the biochar+compost treatment. Biochar and biochar+compost can enhance the nutrient content of the soil in broccoli, cauliflower, and cabbage. In addition, biochar has an effect (positive or negative influence) on disease in test plants. During June observations, the controls had the highest incidence and plant disease severity, whereas adding biochar and biochar+compost reduced disease incidence and plant disease severity. Increased potassium in conjunction with changes in the chemical characteristics i.e. increasing pH, total N, and C- organic of the soil results in the formation of resistance.

Abstract

Aplikasi urea secara intensif dianggap berpotensi menurunkan kualitas tanah, dan kualitas pangan. Kendala aplikasi urea di daerah tropis adalah rendahnya efektifitas karena pencucian dan volatilisasi yang intensif. Penurunan dosis urea dapat dilakukan dengan mengintensifkan aplikasi pupuk hayati karena murah dan terbarukan. Pelapisan urea dengan pupuk hayati dapat memudahkan aplikasi kedua jenis pupuk. Dalam penelitian kami sebelumnya, urea berlapis pupuk hayati padat telah diformulasikan dengan menggunakan Bacillus subtilis, B. megaterium, Azotobacter chroococcum dan A. vinelandii. Penelitian ini bertujuan untuk membuktikan pengaruh urea berlapis pupuk hayati (UBPH) terhadap pertumbuhan dan hasil tanaman selada (Lactuca sativa L.) cv. Romain; dan penurunan dosis urea pada satu musim tanam. Percobaan lapang menggunakan rancangan acak kelompok dengan lima perlakuan dan lima ulangan. Pertanaman selada diberi satu dan setengah dosis dari dua formulasi UBPH. Hasil penelitian menunjukkan bahwa tidak ada perbedaan pertumbuhan, serapan P dan hasil yang nyata antara tanaman yang diberi UBPH dan urea konvensional tetapi setengah dosis UBPH menghasilkan produktivitas selada yang sama dengan satu dosis urea konvensional. Aplikasi setengah dosis UBPH menghasilkan serapan N tajuk yang sama dengan satu dosis urea meskipun terdapat satu formula UBPP yang menurunkan serapan N. Hasil penelitian menunjukkan bahwa aplikasi pupuk urea yang dilapisi dengan pupuk hayati padat dapat disarankan untuk mendukung budidaya selada dan mengurangi dosis urea.

Abstract

Soybean is important commodity because it is consumed by the whole communities. Soybean plays important role in national food security. In fact, the needs for soybeans currently still depend on import of soybean seeds. The stakeholders and communities have made some efforts to increase soybeans production, and one of them is providing superior and high-qualified varieties, as well as profitable for farming. Objective of the study was to know relationship between agronomic characters and economic values in soybean varieties assessment. The study was to analyze the farming of new superior varieties in comparison with local superior varieties by applying different dose of fertilizer. Furthermore, the research was carried out to look for superiorities of the varieties before they are released. Conclusions of the research are (1) the harvest yield per hectare showed that the treatment of YS2 and YS3 have the highest yields with average values 2.4 and 2.2 tons/ha, respectively. (2) The highest farming income was derived from the treatment of YS0, (3) Extra expenses for farming which were expended for both varieties of Yasi 6 and Grobogan will be able to increase the harvest yield but could not afford to raise income, (4) Yasi 6 could be cultivated in accordance with the farmers’ habits and will be able to raise income.

Abstract

Ketersediaan air sangat berperan dalam siklus hidrologi lingkungan, dimana dalam konsepnya menyatakan jumlah air disuatu luasan tertentu dipermukaan bumi dipengaruhi oleh besarnya air yang masuk (input) dan keluar (output) pada jangka waktu tertentu. Ketidakseimbangan air dapat menyebabkan terjadinya kelebihan (surplus) dan defisit (kekurangan air) dan dapat berdampak pada berbagai sektor, salah satunya di sektor pertanian tanaman pangan yakni terjadinya pergeseran musim dan perubahan pola tanam. Dampak tersebut dapat diminimalisir bila dilakukan pengelolaan yang baik terhadap lahan dan lingkungannya yakni melalui perhitungan kondisi neraca air dalam suatu wilayah. Penelitian ini bertujuan untuk (1) menganalisis sebaran spasial neraca air lahan di wilayah hujan tipe D, (2) menetapkan Waktu dan Pola Tanam berdasarkan Neraca Air lahan Padi dan Palawija di wilayah hujan tipe D. Penelitian ini menggunakan metode survei dan analisis perhitungan neraca air. Hasil penelitian menunjukkan bahwa surplus air di wilayah Kecamatan Palangga dan Baito memiliki periode surplus 8 bulan dengan nilai 192, 40 mm/bulan yang terjadi pada bulan Juni dan terendah 2,04 mm/bulan yang sebarannya meliputi semua titik pengambilan sampel adapun secara administrasi meliputi desa Kiaea, Watudemba, Watumerembe, Wawonggura, Eewa, Onembute, Anggondara, Mekar Sari, Wawouru, Aosole, Sanggi-sanggi, Palangga, Tolihe, Sambahule, Matabubu, Mekarjaya, Wonua Raya, Ahuangguluri, Amasara, Wawouru, Mekarsari, Anggondara, Aosole, Eewa dan Onembute. Defisit air di wilayah Kecamatan Palangga dan Baito memiliki periode 4 bulan dengan periode tertinggi pada bulan Juni yakni 58,59 mm/bulan di titik 6 dan terendah pada bulan Februari dengan nilai 4,68 mm/bulan di titik 2. Wilayah Kecamatan Palangga dan Baito memiliki pola tanam jagung+kacang hijau-padi sawah-bero/sayuran; kedelai/padi sawah-bero/sayuran; jagung+kacang tanah-padi sawah-bero/rumput pakan.

Abstract

Tourism villages can develop if the community supports them. To accomplish a goal, a community that is part of the institution must be able to perform its duties and functions as a unitary institution. The institutions have to communicate with one another and work together to develop Lerep Tourism Village. This research will outline the roles of each institution and examine this synergism. Based on the institutions participating in the management of the Lerep Tourism Village, the location was chosen using a purposive sampling strategy. This is a qualitative approach with case study research. Purposive sampling was used to select 26 informants to interview, covering head of village and hamlets, leaders and members of institutions, representative of communities from 4 hamlets. In-depth interviews, observation, and documentation were utilized to obtain the data, and evaluated using Miles Huberman’s flow model. The data’s veracity was examined using source triangulation and technique triangulation. The results show that each institution namely Government Institution, Economic Institution, Art and Cultural Institution, Agricultural Institution, and Environmental Institution plays different roles. There are varieties of purposes in institutional synergy. However, institutions have implemented elements of effective communication and coordination. Such synergies lead to the establishment of new tourist attractions and facilities, increase in the number and satisfaction of visitors, job opening and increase in community income, moreover receiving recognition and passing the certification process. There needs to be discussions and follow-up process regarding improving the internal conditions of institutions and communities between hamlets.

Abstract

One of the important problems in soybean production is the weed growth. This study was conducted to observe the growth of weeds in the growth of soybean plants that are given compost. Anjasmoro soybean varieties were planted in Surakarta, on April 14, 2020. There are four types of treatment, namely given compost fertilizer made from tobacco leaves, soursop leaves, a mixture of tobacco leaves and soursop, and without fertilizer. Weeds were allowed to grow together with soybeans in 15 polybags, per treatment. Observation and identification of weeds were carried out twice, 4 weeks after planting and at harvest time. The results found 9 kinds of weeds consisting of 5 species of Monocots and 4 types of Dicotiles. The total wet weight of weeds was every treatment: 1,539 grams, while the wet weight of the soybean crop at harvest was 858.4 grams. Wet weed weight in the control treatment was 284,8 grams. The wet weight of weeds in soybean plants was the largest mixture fertilizer treatment that is 514,8 grams. The number of pods ranges from 17 to 26. The sum of seeds per soybean plant in giving mixed compost is at most 98 grains. Mixed fertilizer treatment can increase the yield of Anjasmoro soybean, although weed growth up.

Abstract

As the standard of living increases, the orientation of food consumption shifts from fulfilling intake to fulfilling nutrition. The acquisition of sustenance by means other than farming and government aid can enhance nutritional satisfaction, increasing energy consumption as a measure of food security. This study aimed to assess the impact of food acquisition outside expenditure on the food security of cassava farmer households in Wonogiri Regency. The research was conducted in July 2022. The method of analysis was descriptive quantitative with purposive location determination. A representative sample of 80 households was chosen by applying the proportionate allocation formula. Data were collected using 2 x 24-hour Food Recall. The data analysis in this study focused on three key variables: income, the proportion of food spending, and the Wilcoxon test of energy consumption and food security among farmer households. These variables were examined before and after food acquisition from external sources. The results showed that the average monthly income of farmers was Rp4,985,487.00. The proportion of food expenditure amounted to 33.36 percent. Wilcoxon test showed a significant difference in energy consumption before and after food acquisition outside expenditure. The food security classification of cassava farmer households before the acquisition of food outside expenditure showed that 21.25 percent were classified as food secure, 15 percent were classified as food susceptible, 52.5 percent as food insecure, and 11.25 percent as severely food insecure. After the additional food outside expenditure, the food security classification increased, with 45 percent classified as food secure, 23.75 percent as food susceptible, 25 percent as food insecure, and 6.25 percent as severely food insecure. This finding demonstrates that food utilization from farming and the Non-Cash Food Assistance (Bantuan et al./BPNT) program positively impacts the food security conditions of cassava farmer households in Wonogiri Regency.

Abstract

Food security in Indonesia can realized when the population’s food needs are met. One of the efforts to increase food security carried out by the Food Security Agency under the Indonesian Ministry of Agriculture is implementing the Sustainable Food Yard (SFY) program or Pekarangan Pangan Lestari (P2L) in Indonesia. The SFY program utilizes yards, idle land, or empty land for agricultural activities. Semarang City includes the regions that have received the SFY program since 2020. This research aims to determine the status of food security and the role of the SFY program on the food security of farm households participating in the SFY program in Semarang City—the research conduct using a survey method on 130 farm household samples. The data collection technique is in the form of interviews using a 24-hour food recall questionnaire. The data obtained was then processed using cross-tabulation analysis between energy sufficiency percentage and food expenditure shared with the Microsoft Excel application to determine the food security status of farm households. The role of the SFY program on the food security of participating farm households was analyzed descriptively. The research results show that the distribution of food security status of farm households participating in the SFY program in Semarang City is 88.46 percent food secure, 3.08 percent vulnerable, and 8.46 percent questionable. The role of the SFY program in the food security of farm households is not very significant in increasing energy consumption and reducing household food expenditure.

Abstract

This study was carried out in field of Sulimani Polytechnic University, Halabja Technical College of Applied Sciences, Department of Agriculture Project Management, in 2021-2022 to test of different types of peat moss (Latvia, Iraq, Turkish, Germany, and Holland), and various level of peat moss (0,2.5, and 5 percent) on the growth and yield of radish plant (Raphanus sativus). This experiment was designed complied random block design (RCBD), with fifteen treatments and three replications. As results, the morphological properties (chlorophyll, leave tall, leave weight before and after dry, root tall, root diameter, root weight before and after dry, root and leaves dry, root and leaves water content) showed that the statistically not significant different between treatments. However, the highest chlorophyll was taken from treatment Iraq+ level 5 percent (23.967). Also, the highest leave tall, leave weight before dry, root dimeter, root tall, and root weight before and after dry was obtained from treatment that consist of Germany peat moss + level 5 percent (18.4 cm, 22.2 g, 8.4 cm, 39.157 mm, 58.433 g, 2.333 g) respectively. Also, the maximum of leaves weight (g) after dry was obtained from the treatment of Holland peat moss + level 5 percent (2,6 g). Furthermore, the interaction between treatment showed statically not significant different between them. Thus, application of peat moss is important to cultivation of radish and organic crop production. Even so, recommendation to the farm and scientist to use higher level that the level used in this study.
