<p>ABSTRACT<br /> <br />Tidal swamp lands containing acid sulphate is easily become idle land, which can be fixed by reducing oxidation process of pyrite (FeS2). The pyrite oxidation causes disturbance on the growth and yield of rice plant. An experiment was conducted by means soil leaching in order to reduce accumulation of pyrites. The research had been conducted in Simpang Jaya village, Barito Kuala District in 2012 using a split plot design with three replications. As the main plot was leaching, and no leaching treatment, while as the subplot was soil tillage, i.e., 1) control, 2) weeds cleared without tillage, 3) soil tillage at a depth of 15 cm, and 4) soil tillage at a depth of 30 cm. The results showed that the leaching treatment combined with tillage at a depth of 15 cm or 30 cm increased the number of rice tillers, shoot dry weight, and number of panicles per hill, and number of seeds per hill, thus the leaching treatment was able to increase rice production.</p><p>Keywords: acid sulphate, leaching, pyrite, tidal swamp land</p>
Latar belakang: Angka Kematian Ibu (AKI) merupakan salah satu indikator pembangunan kesehatan di Indonesia. Upaya percepatan penurunan AKI dapat dilakukan dengan menjamin agar setiap ibu mampu mengakses pelayanan kesehatan ibu hamil yang berkualitas. Apabila antenatal care dimanfaatkan dengan baik maka kesehatan ibu dapat terpantau secara berkesinambungan dari masa kehamilan sampai dengan persalinan. Metode: Desain penelitian adalah kuantitatif dengan rancangan cross sectional study. Populasi pada penelitian ini adalah semua ibu yang memiliki bayi usia 0-11 bulan di Kabupaten Gowa sebanyak 122 orang. Sampel sebanyak 93 orang diambil dengan menggunakan teknik accidental sampling, besar sampel ditentukan dengan menggunakan rumus Slovin Hasil: Persepsi ibu hamil terhadap peran petugas kesehatan dalam pelayanan antenatal berdasarkan pengorbanan moneter tidak menunjukkan korelasi. Ibu hamil yang memiliki persepsi pengorbanan moneter kecil dan mengatakan peran petugas kesehatan kurang dalam pelayanan antenatal sebanyak 90,0%. Ibu hamil yang memiliki persepsi pengorbanan moneter sangat kecil dan mengatakan peran petugas kesehatan kurang sebanyak 83.1%. Sedangkan persepsi pengorbanan waktu menunjukkan adanya korelasi dengan peran petugas kesehatan dalam pelayanan antenatal. Ibu hamil yang memiliki persepsi pengorbanan waktu besar dan mengatakan peran petugas kesehatan kurang dalam pelayanan antenatal sebanyak 100%. Ibu hamil yang memiliki persepsi pengorbanan moneter besar dan mengatakan peran petugas kesehatan kurang dalam pelayanan antenatal sebanyak 90.2%. Kesimpulan: Persepsi ibu hamil terhadap peran petugas kesehatan dalam pelayanan antenatal berdasarkan pengorbanan moneter tidak menunjukkan korelasi sedangkan berdasarkan pengorbanan waktu menunjukkan ada korelasi. Perlu meningkatkan kecepatan proses pelayanan pemeriksaan kehamilan pada ibu hamil oleh tenaga kesehatan. Kata kunci: Pelayanan antenatal, Ibu Hamil, Pengorbanan, Waktu, Moneter Abstract Background: Maternal Mortality Rate (MMR) is one indicator of health development in Indonesia. Efforts to accelerate the reduction of MMR can be done by ensuring that every mother is able to access quality maternal health services. If antenatal care is utilized properly, maternal health can be monitored continuously from pregnancy to delivery. Methods: The study design was quantitative with a cross sectional study design. The population in this study were all pregnant women who had a gestational age of 7 to 9 months in Gowa Regency as many as 122 people. A sample of 93 people was taken using accidental sampling technique, the sample size was determined using the Slovin formula. Results: Perception of pregnant women towards the role of health workers in antenatal care based on monetary sacrifice did not show a correlation. Pregnant women who have a perception of small monetary sacrifice and say the role of health workers is lacking in antenatal care are 90.0%. Pregnant women who have a perception of monetary sacrifice are very small and say the role of health workers is less as much as 83.1%. While the perception of sacrifice of time shows a correlation with the role of health workers in antenatal care. Pregnant women who have the perception of sacrifice of big time and say the role of health workers lacking in antenatal care as much as 100%. Pregnant women who have a perception of great monetary sacrifice and say the role of health workers is lacking in antenatal care are 90.2%. Conclusion: Perception of pregnant women towards the role of health workers in antenatal care based on monetary sacrifice does not show correlation while based on time sacrifice shows there is correlation. Need to increase the speed of the process of pregnancy examination services for pregnant women by health workers. Keywords: Antenatal care, Pregnant Women, Sacrifice, Time, Monetary
Tindakan tidak aman (unsafe action) adalah tindakan yang dapat membahayakan pekerja itu sendiri maupun orang lain yang dapat menyebabkan terjadinya kecelakaan yang dapat disebabkan oleh berbagai hal seperti tidak memakai APD, tidak mengikuti prosedur kerja, tidak mengikuti peraturan keselamatan kerja dan bekerja tidak hati-hati. Tujuan penelitian ini adalah untuk mengetahui faktor yang berhubungan dengan tindakan tidak aman (unsafe action) pada pekerja dibagian produksi PT Sermani Steel. Metode penelitian yang digunakan penelitian kuantitatif dengan pendekatan cross sectional. Populasi pada penelitian ini yaitu seluruh pekerja yang ada di bagian produksi PT. Sermani Steel yaitu sebanyak 47 pekerja. jumlah sampel sebesar 47 diambil menggunakan teknik total sampling. Data diproleh menggunakan kuesioner. Hasil uji statistik dengan menggunakan chi-square Hasil penelitian ini menunjukkan bahwa tidak ada hubungan pengetahuan dengan tindakan tidak aman (p value= 0,335), tidak ada hubungan masa kerja dengan tindakan tidak aman (p value= 0,197), tidak ada hubungan beban kerja dengan tindakan tidak aman (p value= 0,326), ada hubungan kelelahan kerja dengan tindakan tidak aman(p value= 0,000), tidak ada hubungan pengawasan dengan tindakan tidak aman(p value= 0,122).
Indonesia has a wet tropical climate which is part of its territory crossed by the equator. The rice planting period in Indonesia follows the climatic conditions generally divided into two planting seasons, namely the rainy season from October to March and the dry season from April to September. Almost every 3 to 5 years extreme climate changes occur namely El-Nino and La-Nina which have an impact on rice production. Nationally, the extreme climate phenomenon above showed the effect on rice production. El-Nino during the year 1970–2010 was reported to cause a decrease in rice production around -4.08%, while La-Nina in the same period caused an increase in production by about 1.78%. However, the two extreme climatic conditions had reduced rice productivity by -0.50% and -0.65%, respectively. Most of the tidal swamplands have long been cleared and used for the cultivation of lowland rice. In an effort to optimize tidal swampland as a source of rice production in the future, several strategic actions are needed. The purpose of this paper is to uncover the effects of extreme climate change (El-Nino and La-Nina) on rice production and productivity in tidal swamplands and strategic efforts to overcome the decline in rice production due to the extreme climate changes.
Lahan rawa pasang surut ke depan memegang peranan penting dalam peningkatan produksi padi untuk mendukung swasembada pangan. Percepatan swasembada pangan dapat dilakukan melalui demontrasi plot teknologi budidaya padi. Untuk mendapatkan paket teknologi pengelolaan terpadu yang adaptif mendukung pengembangan padi di lahan rawa pasang surut, dilakukan kegiatan diseminasi pada lahan petani Desa Matang Danau, Kecamatan Paloh, Kabupaten Sambas, Provinsi Kalimantan Barat. Kegiatan dilakukan pada musim kemarau (MK) 2018, musim hujan (MH) 2018/2019 dan MK 2019 masing-masing seluas 50 ha yang terdiri dari 5 ha paket teknologi introduksi (P1) dan 45 ha paket teknologi petani (P2). Teknologi yang diterapkan terdiri: penggunaan varietas unggul, penyiapan lahan, pengelolaan air, sistem tanam jarwo 2:1, dan pengelolaan hara. Pengumpulan data dilakukan melalui catatan kegiatan harian dan survei. Hasil kegiatan diseminasi menunjukkan bahwa hasil padi unggul pada MK 2018 berkisar antara 2,44 - 5,39 ton/ha GKG, musim hujan 2018/2019 berkisar 7,3 - 8,4 ton/ha GKG dan MK 2018 2,4 -4,4 ton/ha. Secara ekonomi dari perbaikan teknologi budidaya padi varietas unggul sebanyak 8 varietas pada MK 2018, 5 varietas pada MH 2018/2019 dan 6 varietas pada MK 2019 mempunyai prospek baik untuk dikembangkan pada skala luas. Persepsi petani terhadap budidaya padi unggul introduksi pada skala peringkat setuju.
