Abstract

Optimization of The Use of Production Inputs on Cassava Farming on Dry Land in Central Java. The cassava farming in Central Java is not the main farming developed in dry land.   Utilization of dry land for cassava production requires adequate productin inputs.  This research aimed to know : 1) performance the use of production inputs, 2) factors that affect the production of cassava, and 3) optimization of the use of production inputs. The research was done in three areas of cassava development, namely Wonogiri, Pati and Purworejo district on April-December 2016.  Multiple regression linear was used to analysis the factors influencing production and was continued by optimization test.  The result showed that planting area and Phonska fertilizer have positive effect, while SP-36 fertilizer have negative effect on cassava production.  Therefore, to obtain the maximum production, the farmers reduce SP-36 fertilizer because it was not optimal and addition of Phonska fertilizer because it was less than optimal.optimization, production inputs, cassava Usahatani ubi kayu di Jawa Tengah merupakan usahatani sampingan yang dikembangkan di lahan kering.  Pemanfaatan lahan kering untuk usahatani ubi kayu memerlukan input produksi yang memadai.  Penelitian bertujuan untuk mengetahui : 1) keragaan penggunaan input produksi, 2) faktor-faktor yang mempengaruhi produksi ubi kayu, dan 3) optimasi penggunaan input produksi pada usahatani ubi kayu.  Penelitian dilaksanakan di tiga kabupaten yang merupakan wilayah pengembangan ubi kayu, yaitu di Kabupaten Wonogiri, Pati dan Purworejo pada bulan April-Desember 2016.  Untuk menganalisis faktor-faktor yang mempengaruhi produksi dengan menggunakan regresi linear berganda, dilanjutkan dengan uji optimasi penggunaan input produksi.  Hasil analisis fungsi produksi menunjukkan bahwa luas tanam dan pupuk Phonska berpengaruh positip, sedangkan pupuk SP-36 berpengaruh negatif terhadap produksi ubi kayu.  Oleh karena itu untuk mendapatkan produksi yang maksimal petani perlu mengurangi jumlah pupuk SP-36 karena sudah berlebih dan menambah pupuk Phonska karena jumlahnya belum optimal.optimasi, input produksi, ubi kayu

Abstract

Budidaya padi merupakan salah satu sumber potensial penyumbang gas rumah kaca seperti gas methan (CH4), yang menyumbang sekitar 11% berupa emisi gas CH4di dalam atmosfer. Implementasi pengelolaan tanaman terpadu (PTT) padi sawah ramah lingkungan diharapkan mampu menekan emisi gas methan. Pengkajian telah dilaksanakan dengan tujuan untuk mendapatkan paket teknologi PTT padi Ramah Lingkungan yang  meningkatkan hasil padi dan menurunkan emisi gas methan pada lahan sawah irigasi. Pengkajian di lahan petani (“Onfarm research”) telah dilaksanakan pada daerah penghasil varietas Rojolele yaitu di Desa Gempol, Kab. Klaten dari bulan Maret sampai bulan September 2016 seluas 1,8 ha yang melibatkan sembilan petani binaan, setiap petani seluas 0,20 hektar. Rancangan Acak Kelompok digunakan dengan delapan ulangan. Dua jenis PTT Padi Ramah Lingkungan dan Pengelolaan Tanaman Terpadu Padi eksisting.Pertama, PTT Padi  Ramah Lingkungan (PTTRL)) teridiri atas dua sumber pupuk organik yaitu pupuk kandang (PTTPukan)  dan petroganik (PTTPetro) . Kedua, PTT eksisting yang dominan (PTTExist). Data yang dikumpulkan meliputi tinggi tanaman, jumlah anakan, komponen hasil dan hasil padi. Pengamatan emisi (gas CH4 dan gas N2O) dengan menggunakan “sungkup”  pada umur 42, 63, 105 dan 112 Hari setelah tanam (Hst). Pengukuran emisi rumah kaca dilaksanakan di Kantor Balingtan Pati. Analisis data menggunakan Uji beda Duncan pada taraf 0,05. Hasil penelitan menunjukkan bahwa  (1) Penerapan (PTTPetro) memberikan hasil yang tertinggi (5,219 t GKP/ha) meningkatkan hasil sebesar 30 % di atas kontrol ((3.620 t GKP/ha), dan menurunkan emisi gas CH4 sebesar 13,6% di bawah kontrol (emisi:76,05kg CH4/ha/musim).

Abstract

Lahan sawah tadah hujan memiliki kesuburan dan ketersediaan air yang rendah, namun masih menjadi sumber pendapatan petani. Penelitian dilaksanakan di Desa Gemolong, Kecamatan Gemolong, Kabupaten Sragen dari Oktober–Desember 2021, dengan metode survei. Penelitian bertujuan untuk mengetahui kelayakan finansial usahatani padi, sumber pendapatan dan pengeluaran rumah tangga dan mengidentifikasi kesejahteraan rumah tangga. Hasil penelitian menunjukkan bahwa pendapatan petani dari usahatani padi sebesar Rp21.050.905,00/ha/musim. Pendapatan rumah tangga petani berasal dari usahatani padi, usahatani jagung, dan luar pertanian dengan kontribusi 41,52 persen, 18,88 persen, dan 39,60 persen. Distribusi pendapatan digunakan untuk konsumsi pangan (31,10 persen), konsumsi nonpangan (41,89 persen), biaya usahatani (22,84 persen), dan 4,16 persen pendapatan tidak dibelanjakan. Rata-rata rumah tangga petani lahan sawah tadah hujan berada dalam kondisi sejahtera, ditunjukkan dengan nilai pendapatanlebih besar dibandingkan nilai pengeluaran, pendapatan perkapita lebih tinggi dari angka garis kemiskinan dan nilai tukar pendapatan rumah tangga sebesar 1,78. Pekerjaan di luar pertanian mengurangi jumlah rumah tangga di bawah garis kemiskinan dari 9 menjadi 2 rumah tangga dan meningkatkan jumlah rumah tangga sejahtera dari 31 menjadi 38 rumah tangga. Oleh karena itu, untuk meningkatkan kesejahteraan rumah tangga petani diharapkan dapat memberi pelatihan keterampilan agar petani memiliki akses terhadap kesempatan kerja di daerah pedesaan, baik di sektor pertanian maupun nonpertanian.

Abstract

Lone wolf terrorism is terrorism committed by individuals without direct affiliation with large terrorist organizations. This phenomenon is increasingly worrying in various countries, including Indonesia. Attacks by self-radicalized individuals have a different pattern from conventional terrorism, as the perpetrators act alone and are difficult to detect by security forces. In Indonesia, the increase in Lone Wolf terrorism cases in recent years is due to the easy access to the internet and social media that spread radicalism. The city of Surabaya came under scrutiny after the terrorist attacks in May 2018, where several acts were linked to large networks such as Jamaah Ansharut Daulah (JAD). The government and local communities, such as the Community of Peace Fighters, have tried to prevent radicalization through deradicalization programs and monitoring of vulnerable individuals. However, the individualistic and disorganized nature of lone wolf terrorism makes it difficult to anticipate. This research aims to identify patterns of radicalization that can give rise to lone terrorists, who are not directly affiliated with terrorist groups. The method used is interdisciplinary legal research with a qualitative approach, which was carried out at the Surabaya Peace Fighters Community, which is under the guidance of the Special Da'wah Institute (LDK) of the Muhammadiyah Regional Leadership (PWM) of East Java. The results of this study show that there are so many external factors that make a person radicalized. One of them is ideological factors, social conditions, structural injustices that encourage them to rebel, and the most powerful is the understanding that radical actions are justified by religious teachings (Islam).
