Publisher : Universitas Wahid Hasyim

Pembangunan pertanian dapat diartikan sebagai suatu proses yang ditujukan untuk selalu menambah produksi per kapita, yang sekaligus dapat mempertinggi pendapatan dan produktivitas usaha tiap-tiap petani dengan jalan menambah modal dan ketrampilan untuk memperbesar turut campur tangannya manusia di dalam perkembangan tumbuh-tumbuhan dan hewan. Dalam pembangunan pertanian, diversifikasi pada umumnya dihubungkan dengan suatu peralihan atau perpindahan dari komoditas ekspor untuk ke arah pengusahaan komoditas baru yang dipandang sebagai jalan keluar dalam menghadapi permintaan pasar. Diversifikasi pertanian adalah suatu pemilihan dan adopsi dari beberapa tambahan tipe komoditas yang berorientasi pasar, untuk dihasilkan melalui budidaya pertanian secara modern, baik pada tingkat nasional maupun regional. Perumusan masalah yang diajukan dalam penulisan makalah ini adalah:1. bagaimanakah karakteristik pelaku sistem agribisnis untuk mencapai pertanian yang tangguh?2. Upaya apa yang harus dilakukan agar pengembangan diversifikasi pertanian berhasil? Lembaga ekonomi yang tangguh harus memiliki ketrampilan dalam menerapkan inovasi untuk terus meningkatkan produktivitas efisiensi usaha. Mengusahakan untuk memperoleh keuntungan yang layak diukur dengan tingkat kewajaran yang berkembang terus. Lembaga ekonomi harus mampu menghadapi risiko usaha dari perubahan situasi ekonomi di dalam maupun di luar negeri, juga dapat memanfaatkan skala usaha untuk mencapai efisinsi yang tinggi. Ciri ketagguhan lainnya dari lembaga ekonomi adalah memiliki kemampuan mandiri menghadapi pihak-pihak lain dalam dunia usaha. Lembaga sosial pedesaan haruslah mampu menciptakan iklim yang sehat sehingga para petani produsen dapat mengembangkan usahanya, menciptakan iklim usaha bersaing secara kreatif. Ciri ketagguhan yang lainnya, lembaga sosial dituntut untuk menciptakan iklim yang mendorong anggota masyarakat bekerja keras, ulet dan jujur untuk mencapai tujuan. Untuk menjamin keberhasilan pengembangan diversifikasi pertanian, senantiasa diperlukan adanya pengembangan teknologi pertanian sesuai dengan kebutuhan petani, pengembangan kelembagaan, peningkatan kualitas sumberdaya pertanian, perbaikan gizi masyarakat, perbaikan sistem pemasaran dan perlu adanya campur tangan pemerintah.

Cabai merupakan komoditas hortikultura penting di Indonesia. Cabai banyak dibudidayakan karena memiliki harga jual dan permintaan pasar yang tinggi. Perlu adanya stabilisasi untuk meningkatkan produksi cabai sehingga kebutuhan cabai dapat terpenuhi. Beberapa usaha untuk meningkatkan produksi cabai yaitu pemenuhan unsur hara berdasarkan kebutuhan tanaman cabai. Pemberian pupuk kandang mampu membantu menyediakan hara yang dibutuhkan tanaman cabai tanpa merusak tanah jika digunakan dalam waktu panjang. Peningkatan efektifitas pupuk kandang dapat dilakukan dengan penambahan biofertilizer seperti PGPR. Kombinasi pupuk kandang dan PGPR dapat dijadikan alternatif untuk meningkatkan kesuburan tanah, pertumbuhan, produksi tanaman cabai tanpa menyebabkan kerusakan lahan. Penelitian ini dilaksanakan pada bulan Maret sampai dengan Juli 2020 di Green House dan Laboratorium Ekologi dan Produksi Tanaman, Fakultas Peternakan dan Pertanian, Universitas Diponegoro, Semarang. Penelitian ini menggunakan rancangan acak lengkap dengan pola faktorial 3x5 dengan 3 ulangan. Faktor pertama (P) yaitu pupuk kandang ayam (P1), pupuk kandang sapi (P2), pupuk kandang kambing (P3). Faktor kedua (B) terdiri dari kontrol/0 ml/liter (B0), PGPR komersial 5 ml/liter (B1), PGPR 5 ml/liter (B2), PGPR 12,5 ml/liter (B3) dan PGPR 20 ml/liter (B4). Data yang diperoleh dianalisis menggunakan analisis ragam (ANOVA). Uji lanjut yang digunakan yaitu uji jarak berganda duncan. Hasil penelitian menunjukkan pemberian pupuk kandang ayam memberikan pertumbuhan dan produksi terbaik pada variabel tinggi tanaman tetapi pupuk kandang ayam tidak berbeda nyata dengan pupuk kandang sapi pada bobot buah per tanaman, jumlah buah per tanaman, dan berat segar tanaman.

Publisher : Universitas Wahid Hasyim

The high temperature exposure on the food containing synthetic sodium nitrite (NaNO2) can cause the formation of harmful compounds of N-nitrosamine carcinogen. Nitrite (NO2-) have also been reported to react with amine in gastric acid to form N-nitrosamine. N-nitrosamine carcinogen can induce tumor in many organs of the human body. The objectives of this study were to investigate the capacity of activity of nitrate reductase (ANR) and determine the formulation of various fresh vegetables that are naturally rich in nitrate (NO3-) as a natural curing agent substitute for synthetic sodium nitrite in beef curing. Natural sources of nitrate of fresh vegetables is expected to be safer and healthier for consumption. The leaf and leaf stalks of fresh celery, fresh red spinach and fresh marigolds were separated and evaluated ANR respectively in their ability to produce nitrite during a certain incubation time. Nitrite in fresh vegetables is utilized to react to pigment beef in complex reactions series of curing. In general, the evaluation of leaf ANR showed higher than leaf stalk ANR of fresh celery and fresh red spinach. Natural nitrite that is generated by leaf of fresh celery, fresh red spinach and fresh marigolds was 0.69; 0.73 and 0.63 mg NO2-/g/h respectively. Natural curing process of beef requires incubation time which allows the conversion of nitrate to nitrite which is sufficient to produce the characteristics of naturally cured beef products similar to the conventional curing using synthetic sodium nitrite. Fresh celery leaf is recommended as a natural curing gent of beef curing because it has long been recognized by consumers more suited to a wide range of processed beef products. Natural curing of beef using fresh celery leaf is recommended as much as 22 g and incubate at room temperature for 2 hours to produce the NO2- equivalent of 30 ppm NaNO2. Key Words: natural curing, natural curing agent, activity of nitrate reductase, fresh celery leaf and beef
