Abstract

Tujuan penelitian adalah untuk mengeksplorasi aspek-aspek yang mempengaruhi petani dalam meningkatkan produksi tanaman pangan dilahan kering iklim kering. Penelitian dilaksanakan di Dusun Brang Pelat, Desa Pelat Kecamatan Unter Iwes, menggunakan pendekatan survei. Pemilihan dan penentuan sampel responden dilakukan secara purposive sampling. Pengumpulan data dilakukan melalui teknik observasi langsung, pencatatan dan wawancara mendalam pada 66 orang responden menggunakan kuesioner. Metode analisis data yang digunakan dalam penelitian adalah analisis deskriptif persentatif. Hasil penelitian menunjukkan bahwa karakteristik demografi, terdiri dari: umur, jenis kelamin, status perkawinan, asal responden, dan tanggungan keluarga. Karakteristik social ekonomi petani lahan kering terdiri dari: pendidikan, pekerjaan utama, pekerjaan sampingan, pengalaman berusaha tani, pendapatan, lama bekerja dalam sehari, luas lahan yang dimiliki, dan kepemilikan lahan.

Abstract

Brantas River is the largest river in East Java, flowing from the city of Batu upstream until downstream in Surabaya and Sidoarjo. This river plays a crucial role as a vital natural resource that supports the various needs of the surrounding communities. This study serves as a preliminary investigation with the primary aim of assessing the water quality in three different zones of the Brantas River: the upper, middle, and downstream sites. Additionally, this research includes a review to identify the organisms exposed to water pollution in the Brantas River. The study was conducted from November 2020 to April 2023, utilizing an exploratory observational method at 19 observation stations. The data obtained was subsequently analyzed using a descriptive approach. Various parameters were observed, including pH (a measure of acidity or alkalinity), hardness (the concentration of calcium and magnesium ions), alkalinity (the capacity of water to neutralize acids), nitrate, nitrite, fluoride, and heavy metals such as lead (Pb), copper (Cu), and iron (Fe). The research findings indicate that in several upstream areas of the Brantas River, there were elevated hardness, nitrate, lead (Pb), and iron (Fe) that exceeded the established water quality standards. In the middle section of the river, water quality was generally satisfactory, although a few locations exhibited slightly elevated levels of lead (Pb). Meanwhile, all locations downstream of the Brantas River demonstrated water quality that exceeded the prescribed standards. After a literature review, it was discovered that various biota in the Brantas River have been exposed to pollutants, including fish species and plants like Ipomea aquatica and Eichhornia crassipes. Therefore, it is necessary and urgent to improve water management and monitoring plants and biota in the Brantas River to preserve organisms in aquatic and terrestrial ecosystems. Keywords: Brantas river, pollution, water quality

Abstract

Pepaya (Carica papaya L.) merupakan tanaman hortikultura yang banyak dibudidayakan. Tanaman pepaya sangat digemari dikalangan masyarakat Indonesia. Berdasarkan data Badan Pusat Statistik (BPS) produksi pepaya di Indonesia fluktuatif dari tahun 2012 sampai tahun 2014. Fluktuatifnya produksi pepaya disebabkan kurangnya manajemen lahan di kebun pepaya, penggunaan varietas unggul dan ketersediaan lahan pertanian yang terbatas. Peningkatan produksi pepaya pada setiap kebun dapat dilakukan dengan penerapan teknologi lubang resapan biopori berkompos, dimana lubang biopori akan dikombinasikan dengan bahan organik untuk meningkatkan kualitas lahan dan produktivitas di agroekosistem pepaya yang berkelanjutan. Tahapan pelaksanaan kegiatan tersebut dimulai dari persiapan awal, pelaksanaan kegiatan (sosialisasi dan penerapan Lubang Resapan Biopori Berkompos/ LRBB), monitoring dan evaluasi penerapan LRBB pada kebun pepaya.

Abstract

The decreasing land area for coffee cultivation in Indonesia has led to a reduction in coffee production. The availability of land with potential for coffee plantation is also decreasing. As a consequence, coffee is cultivated on less fertile lands, such as lands dominated by clay fraction. This land generally has a low pH so that the nutrient content is more absorbed in Al and Fe which react in an acidic environment. Furthermore, heavy texture of soil also inhibits root growth, making it difficult for plants to absorb nutrients. In this study, biopore infiltration holes were used as a solution to improve acidic soil with a dominant clay fraction. The research was conducted at Agrotechnopark Jatikerto, Malang Regency and the soil analysis was conducted at the Soil Chemistry Laboratory, Faculty of Agriculture, University of Brawijaya during 2020-2022. This research was conducted experimentally with a group randomized design. There were four treatments in this study, namely 1) control/no biopore, 2) 30 cm empty biopore, 3) 30 cm biopore + 2.12 kg compost fertilizer, and 4) 30 cm biopore + 1.05 kg goat manure fertilizer.  The results showed that biopore infiltration holes added with compost or goat manure fertilizer were able to increase pH, soil organic C, CEC, BS, and total N-P-K nutrients. Furthermore, the increase in organic C and total N-P-K nutrients in the study area was also directly proportional to the increase in chlorophyll content and coffee production. The increase in chlorophyll content and coffee production is a result of the increase in chlorophyll content and coffee yield.
