Soybean is the basic material for any kind of industry, such as tofu and tempeh industries. Soybean cultivation will be better if use a sustainable agricultural system, such as using organic fertilizers. This research purpose was to find out the effect of organic fertilizer on the growth and yield of local soybean. The research used a complete randomized design with one factor which was a variety of organic fertilizers with 6 treatments. Various fertilizers used in this research consist of inorganic fertilizer, liquid organic, compost, cow manure, rabbit urine, chicken manure, and goat manure. Each test unit consists of 4 pots (plants) and each was repeated 4 times. The results showed that the provision of compost and goat manure increased the growth of local soybean plants, include plant height and the number of leaves at 42 DAP and leaf area at 28 DAP. The application of various organic fertilizers (liquid fertilizer, compost, cow manure, goat manure, and rabbit urine) is unable to increase the yield and yield components of local soybeans.
Turmeric (Curcuma longa) and ginger (Zingiber officinale) are included in important spice commodities in Indonesia. The altitude and the environmental condition have an impact on the secondary metabolite content in the medicinal plants. Moreover, the current situation of climate change also affecting on the local environmental condition which is impacting on the secondary metabolite production. This research aims for determining the effects of altitude and soil characteristics on secondary metabolites. The research method was surveyed, then purposive sampling on farmlands with different altitude and soil characteristics at Karanganyar District, Indonesia. The variables observed were altitude, climate, soil characteristics (soil pH, Cation Exchange Capacity, Organic Matter, texture, Nitrogen, Phosphorus and Potassium), and secondary metabolites of turmeric and ginger (curcuminoid, gingerol, shogaol). The results indicated that the secondary metabolite of turmeric affected by altitude, soil pH, soil texture sand and soil available phosphorus. On the other hand, the secondary metabolites of ginger are affected by altitude, soil pH, soil organic matter, soil texture (silt and sand), and soil phosphorus. Turmeric and ginger in the highlands were produced more secondary metabolites compared with in lowlands.
Background The environmental conditions resulted by the agronomic management practices may govern the secondary metabolite contents of medicinal plants, including Java tea (Orthosiphon aristatus B). Abiotic factors such as temperatures have been known to determine the secondary metabolite contents of Java tea. This study aimed at evaluating the effects of soil temperature resulting from soil mulching and harvest age on total phenol, flavonoid and antioxidant contents of Java tea. Methods The research was arranged using nested (hierarchy design) with completely randomized design under a screen house at Karanganyar, Indonesia, from July to December 2019. The main factor was soil mulching (control; black plastic mulch, transparent plastic mulch, biodegradable mulch and rice straw mulch) with three replicates. The main factor was nested in the temporal hierarchy factor, namely harvest age which consisted of two levels, i.e., 80 and 100 days. The observation parameters were soil temperature of 10 min (maximum; mean; minimum and soil temperature-based Growing Degree Days, GDD) with sensors and logger; plant growth (plant height, number of leaves, fresh and dry weight); and secondary metabolites including phenol, flavonoids and antioxidant. Results The results confirmed the order of the highest to the lowest mean soil temperature was resulted under the transparent plastic mulch > straw > black plastic mulch > control > biodegradable plastic mulch (26.69 > 26.29 > 26.10 > 26.07 > 25.68 °C, respectively). Overall, the harvest age 100 days resulted in higher plant growth, indicated by the higher fresh and dry weight of biomass, higher phenol and antioxidant contents than 80 days. Soil mulching, especially with plastic and biodegradable plastic mulches with long harvest age (100 days) effected into lower fresh and dry weight of plants. On the other hand, soil mulching indirectly resulted in lower phenol but higher flavonoid contents through higher soil temperature, while antioxidant contents were higher under the big soil temperature-based Growing Degree Day (GDD). The total phenol, flavonoids and antioxidant produced ranging from 193.75 to 412.50 mg GAE/ 100 g DW; 81.13 to 141.47 mg QE/ 100 g DW; and 1875.5–2144.4 µmol TE/g DW. Conclusion Higher maximum soil temperature resulted in lower phenol content, while higher minimum soil temperature and shorter harvest age increased total flavonoid. Longer harvest age produced more total phenol and antioxidant due to bigger soil temperature-based Growing Degree Day (GDD). Graphical Abstract

Climate change such as long drought will have an impact on food supply. Adaptation to these conditions must be conducted by improving food production. This study aims to determine the effect of straw and mycorrhizal use on soil moisture, nutrient availability and uptake as well as upland rice yield. This field trial used 3 x 2 factors, with 4 replications arranged in a Complete Randomized Block Design. The first factor consists of without straw; fresh straw (10 ton/ha); and weathered straw (10 ton/ha). The second factor was without and with mycorrhizae (5 gram/plant). The result showed that the application of fresh straw and weathered straw combine with mycorrhizal inoculation can increase soil moisture, improve the availability of soil N, P, K, increase the uptake of N, P, K. There is a positive correlation between soil moisture content with the uptake of N, P, K on the plant. Moreover, The highest grain yield (3.9 ton/ha) was obtained at the weathered straw combine with mycorrhizae. An application of rice straw in any condition can optimize soil fertility and can be used as a way of adaptation to climate change.
Peternakan di Indonesia didominasi oleh peternakan skala kecil. Peternak ini menjalankan sistem pemeliharaannya dengan sangat sederhana terutama perhitungan kebutuhan pakan belum sesuai dengan kebutuhan ternak. Permasalahan yang lain, saat musim hujan pakan hijauan berlimpah sedangkan di musim kemarau pakan hijauan, terutama rumput, jumlahnya terbatas, sehingga dibutuhkan teknologi pengawetan pakan saat pakan melimpah. Pengabdian kepada masyarakat ini bertujuan untuk mentransfer IPTEK berupa pengolahan pakan fermentasi dengan menggunakan FJLB (fermented juice of ephypitic lactic acid bacteria) di Kelompok ternak Putra Rahayu dan Ngudi Rejeki di Kelurahan Tawang Rejo, Kecapatan Jatipurno, Kabupaten Wonogiri. Kelompok ternak di kelurahan ini beranggotakan petani-petani kecil, dimana kegiatan berternak adalah kerja sambilan dan bukan penghasilan utama. Sehingga rata-rata jumlah ternak yang dimiliki, khususnya ternak ruminansia hanya berkisar kurang dari 5 ekor. Pelatihan pembuatan silase pakan komplit ini dilaksanakan pada tanggal 20 Juni 2021. Metode yang digunakan dalam pengabdian ini pemberian materi atau penyuluhan dan pelatihan. Metode pengambilan data adalah interview dan kuesioner. Tahapan pelatihan dimulai dengan pemberian materi kemudian praktik secara langsung. Mitra mencampur semua bahan konsentrat dan hijauan yang sudah dicacah kemudian dicampur dengan molases dan FJLB. Semua bahan kemudian dimasukkan ke dalam drum sampai padat dan ditutup rapat. Hasil dari kegiatan pengabdian ini adalah peternak meningkat pengetahuannya tentang cara menyusun ransum, cara membuat silase, dan tahu cara membuat FJLB sebanyak 100%. Kegiatan pengabdian ini juga menghibahkan alat berupa pencacah rumput odot dan penggiling jagung. Melalui kegiatan pengabdian ini diperoleh bahwa mitra meningkat pengetahuannya tentang fermentasi pakan silase dan cara pembuatannya. Livestock in Indonesia is dominated by small-scale livestock. This breeder runs a straightforward maintenance system and is not following good and successful farming methods. Feed technology is not yet known, especially the calculation of feed requirements of livestock. Small-scale farmers do not yet understand how to provide the daily amount of feed to their livestock. Another problem is that during the rainy season, forage feeds are abundant. In the dry season, forage feeds, especially grass, are limited, so feed preservation technology is needed in the rainy season so that it can be given during the dry season. This community service aimed to transfer science and technology to process fermented feed using FJLB (fermented juice of ephypitic lactic acid bacteria) in the Putra Rahayu and Ngudi Rejeki livestock groups in Tawang Rejo Village, Jatipurno District, Wonogiri Regency. The livestock group consists of small farmers, where livestock farming is only a side job and not the main income. So that the average number of livestock owned, especially ruminants, is only around five heads. This complete feed silage-making training was held on June 20, 2021. The methods used in this service were interviews, questionnaires and training. After training on making feed silage with FJLB, farmers increased their knowledge about how to prepare rations, how to make silage, and know how to make FJLB. Through this service, tools in the form of a mutton grass chopper and corn grinder are also provided, which are useful for farmers to feed livestock so that they are more efficient and can use the land around their homes for food source plants, namely elephant grass and corn. Through this service activity, it was found that partners increased their knowledge about fermented silage feed and how to make it.
