Low nutrient availability and high soil bulk density are caused by the loss of fertile soil particles due to the kinetic energy of rain. Land management that does not apply conservation principles such as soil covering is one of the factors causing this to happen. This research was conducted to determine the impact of using plastic mulch as one of conservation actions. This research was conducted at the experimental field University of Siliwangi, Mugarsari. Soil samples were taken from mulched and without mulch lands as treatments. Soil samples were collected at 0-10 and 10-30 cm soil depths. Soil samples were taken to analyze the chemical properties of the soils (i.e., pH H2O, organic C, total N, available P, exchangeable K, Ca, Mg, Na) and physical properties (i.e., soil bulk density, porosity, water content, and texture). The results showed that the use of mulch had a significant effect (p<0.05) on pH H2O, organic C, total N, available P, exchangeable K, exchangeable Ca, bulk density, and water content. The results of the correlation showed that increasing organic C in mulched land had an effect on decreasing BD (r = -0.739). In addition, the organic C increased soil porosity (r = 0.612). Meanwhile, soil depth had no effect (p>0.05) on soil chemical and physical properties.

Petani kapulaga di Desa Kalijaya sudah bertahun-tahun membudidayakan kapulaga jenis lokal (Hibrida Dompo), meskipun demikian masih banyak petani yang memilih menjual kapulaga ke tengkulak dalam kondisi basah. Padahal penjualan biji kapulaga dalam kondisi basah menyebabkan harga jual rendah dan membuat tingkat keuntungan yang diterima petani minim. Selain itu, petani juga menghadapi keterbatasan keterampilan dalam penanganan pasca panen, lemahnya kemampuan analisis kelayakan usaha, dan keterbatasan dalam memperluas pasar. Tujuan kegiatan pengabdian masyarakat ini adalah untuk meningkatkan kapasitas petani dalam penanganan dan pemasaran produk kapulaga sehingga mampu menembus pasar ekspor. Kegiatan pemberdayaan masyarakat ini dilakukan dengan metode Participatory Rural Appraisal (PRA) dengan bentuk kegiatan berupa pendampingan dan penyuluhan. Hasil pelaksanaan kegiatan menunjukkan bahwa program pendampingan pemasaran mencapai keberhasilan dengan persentase sebesar 80,53% atau naik sebesar 29,04% dari sebelumnya. Hal ini berarti terjadi peningkatan pengetahuan dan pemahaman petani pasca dilakukan kegiatan pemberdayaan. Keberhasilan juga ditunjukkan dengan adanya kesepakatan penawaran kerjasama antara petani dengan eksportir berupa Letter of Intent (LoI). Selain itu, hasil evaluasi kepuasan kegiatan menunjukkan bahwa seluruh indikator kepuasan mencapai skor rata-rata diatas 4,21 artinya semua indikator termasuk dalam kategori sangat sesuai.

Desa Tanjungpura merupakan salah satu desa di Kecamatan Rajapolah yang memiliki potensi perikanan yang layak untuk dikembangkan. Tingginya antusiasme masyarakat ditunjukkan dengan terbentuknya kelompok budidaya ikan nila bernama Sawala Tanjungbuana. Kelompok tersebut mampu menggerakkan perkonomian desa sektor perikanan melalui budidaya ikan menggunakan sistem bioflok dan saat ini sudah memiliki 15 bioflok. Usaha ikan nila bioflok mengalami perkembangan cukup pesat mengingat permintaannya yang relatif stabil. Namun dalam perjalanannya, banyak aspek yang harus diperbaiki dan ditingkatkan. Berdasarkan hasil observasi, ditemukan berbagai permasalahan diantaranya, belum adanya pemanfaatan limbah bioflok dan limbah kotoran ikan dan produk yang di jual hanya ikan segar. Kegiatan pengabdian ini bertujuan untuk memfasilitasi potensi hilirisasi produk ikan nila baik dari segi diversifikasi produk, sehingga diharapkan terjadi peningkatan mutu dan produksi ikan nila, nilai tambah produk guna memperluas pemasaran produk ikan nila, serta terciptanya kemandirian dan ketahanan pangan

Improving the quality of compost paper is important to increase the availability of nutrients and reduce heavy metals. The quality of compost paper can be improved by using Pseudomonas aeruginosa bacteria, which can help mineralize nutrients and break down or convert heavy metals into less harmful forms. This study used a completely randomized design with five treatments in different concentrations of Pseudomonas aeruginosa bacteria (10%, 15%, 20%, and 25%). The analysis parameters used were pH H2O, Total N, organic C, C:N, Pb and Hg in the resulting compost. The results showed that the KK3 treatment produced higher pH H2O and Total N than other treatments. The availability of Pb metal on KK3 produced a relatively smaller value compared to other treatments, likewise, although it was not significantly different from C. The correlation results showed no significant relationship (p>0.05) between increasing doses of Pseudomonas aeruginosa and the availability of nutrients and heavy metals. The mineralization and incubation processes were factors in the study of improving the quality of compost by using Pseudomonas aeruginosa.

Land in Tawangsari District, Sukoharjo Regency had a limiting factor in the form of water availability. One of the local commodities cultivated for generations on dry land in this region is gembili (Dioscorea sp.). However, the gembili cultivation process has not produced optimal productivity and is threatened with extinction. Therefore, gembili cultivation and use of dry land need to be optimized by carrying out integrated land management. The aim of utilizing dry land is to increase local food production and sustainability as alternative food and maintain national food security. This research was conducted using data on productivity, quantity and type of fertilizer obtained through interviews with gembili farmers and secondary data on soil types obtained from BPP Tawangsari District, Sukoharjo Regency. The results showed that grumusol and lithosol soil types had no significant effect (p > 0.05) on gembili productivity. Providing organic + inorganic fertilizer with giving organic fertilizer without a combination produced values that were not significantly different (p > 0.05). However, the average productivity results were sequentially from grumusol and lithosol (6.1 ton.ha-1 and 7.1 ton.ha-1). Meanwhile, the use of organic fertilizer is 8.06% higher compared to organic fertilizer + inorganic fertilizer. The results of the multiple regression test for organic fertilizer had a significant effect (p < 0.05) on the productivity of Dioscorea sp..
