Abstract

One of the obstacles in efforts to increase rice productivity is the damage caused by the attack of the rice stem borer. Annual yield loss caused this insect pests is quite high, reaching 10-30%. The attack of stem borer has long been encountered and is a problem in rice producing areas on Buru Island, such as in Savanajaya Village. This study aimed to obtain data on the types of pests, population levels and the intensity of damage in five rice varieties due to stem borer attact and to determine the varieties that had the lowest population and damage intensity in the Saavanajaya Village, Waeapo District, Buru Regency. The method used was a survey method that focused on five varieties of rice cultivated by farmers, to obtain population data and the intensity of damage. The results showed that the type of pest that attacked the five rice varieties of IR-64 variety in Savanajaya Village was the white rice stem borer (Scirpophaga innotata), with the highest larval population (per cluster) of 1.27 individuals and the intensity of damage 5.20%, followed by Cigeulis variety with a larval population of 1.17 individuals and damage intensity of 4.70%, the Ciherang variety with a larval population of 1.07 individuals and damage intensity of was 4.25%, the Mekongan variety with a larval population of 1.1 individuals and damage intensity of 4.15%, and the lowest was the Membramo variety with a larval population of 1.03 larvae and damage intensity of 4.12%. The damage intensity of at the study site, although different between varieties, could all be classified into the category of mild attack.

Abstract

Organic fertilizers have an important role in the success of vegetable cultivation. Marine mud contains a lot of nutrients and organic matter, so it is useful for improving degraded soils in the short term and a source of nitrogen and minerals (especially Ca and Mg) in the long term. This study aimed to examine and explain the effect of doses of cow dung fertilizer and marine mud, for the growth and yield of spoon mustard (Brassica rapa L). This research was conducted at the Plastic House of the Faculty of Agriculture, Pattimura University, from June to August 2018. The experiment in this study was a factorial experiment in a completely randomized design with two factors. The first factor was sea mud from Tulehu Village (L) with 4 levels, namely: without sea mud (control), 100 g, 200 g and 300 g per kg of soil. The second factor was cow manure (K) with 4 levels, namely: without cow manure (control), 5 g, 10 g. and 15 g per kg of soil. The variables observed included plant height, leaf number, leaf area, plant biomass fresh weight, crown fresh and root fresh weight. Data were analyzed using Analysis of Variance (ANOVA) and further test using Duncan's test at 0.05 level. The results showed that the sea mud treatment had a very significant effect on the variables of plant height (3, 4 and 5 weeks after planting, WAP), leaf number (4 and 5 WAP), leaf area, plant biomass weight and plant crown weight, number of leaves (3 WAP) and root weight, but had no significant effect on plant height at age (1 and 2 WAP), and number of leaves (1 and 2 WAP). The treatment of cow dung fertilizer had a very significant effect on the variables of plant height (2, 4 and 5 WAP), number of leaves (3 and 5 WAP), plant biomass weight and plant crown weight, a significant effect on plant height (3 WAP), leaf number (4 WAP), but had no significant effect on plant height (1 WAP), leaf number (1 and 2 WAP), leaf area and root weight of plants. The interaction between the treatment of marine mud and cow manure gave a very significant effect on plant height (4 and 5 WAP), but there was no interaction on the other observation variables. Keywords: cow manure, marine mud, ‘spoon’ mustard, Ultisol soil ABSTRAK Pupuk organik mempunyai peranan penting terhadap keberhasilan budidaya tanaman sayuran. Endapan lumpur laut banyak mengandung unsur hara dan bahan organik, sehingga bermanfaat untuk memperbaiki tanah-tanah terdegradasi untuk jangka pendek dan sumber nitrogen dan mineral (khususnya Ca dan Mg) untuk jangka waktu panjang. Penelitian ini bertujuan untuk menguji dan menjelaskan pengaruh dosis pupuk kotoran sapi dan dosis lumpur laut untuk pertumbuhan dan produksi tanaman sawi sendok (Brassica rapa L).

Abstract

The use of satellite imagery in agriculture has been widely used, for example in plantation areas or in rice fields. Satellite imagery can estimate the area of paddy fields and estimate rice production; however, the application of satellites for mapping the planting season in rice fields using Landsat 8 OLI imagery and NDVI (Normal Difference Vegetation Index) transformation has not been widely undertaken. This study aimed to analyze the growing season in paddy fields based on the results of NDVI analysis of Multitemporal Landsat 8 OLI imagery. Based on the results of research analyzed from the spectral value of NDVI images recorded in March and May 2020 then added with the results of observations and farmer interviews in September 2020, it was found that there were color differences in NDVI images caused by differences in planting time or plant age at the time of recording the image. The planting season in rice fields in the Buru regency was generally two times per year or five times per two years. The increase in the rice planting season could be realized due to the availability of water in the field that was sufficient for the growth of rice plants, both from irrigation and rainfall. Based on the interpretation of the images used and field checks, it was found that the accuracy test results showed the overall accuracy of 88%. The overall accuracy value is considered correct if it exceeds the tolerance limit given, which is ≥ 80%. Keywords: Buru Regency, growing season, Landsat 8, NDVI, paddy fields ABSTRAK Pemanfaatan citra satelit pada bidang pertanian telah banyak dilakukan, misalnya pada areal perkebunan ataupun pada areal persawahan. Citra satelit dapat menduga luas lahan sawah sampai dengan menduga produksi padi; tetapi pemanfaatan citra satelit untuk pemetaan musim tanam di lahan sawah menggunakan citra Landsat 8 OLI dan transformasi NDVI (Normalized Difference Vegetation Index) sampai saat ini belum banyak dilakukan. Penelitian ini bertujuan untuk Menganalisis musim tanam di lahan sawah berdasarkan hasil analisis NDVI Citra Landsat 8 OLI Multitemporal. Berdasarkan hasil penelitian yang dianalisis dari nilai spektral citra NDVI perekaman bulan Maret dan Mei tahun 2020 ditambah dengan hasil pengamatan serta wawancara petani pada bulan September 2020 didapatkan adanya perbedaan warna pada citra NDVI yang diakibatkan oleh perbedaan waktu tanam ataupun umur tanaman pada saat perekaman citra. Musim tanam pada lahan sawah di Kabupaten Buru umumnya dua kali per tahun atau lima kali per dua tahun. Peningkatan musim tanam padi dapat terealisasi karena ketersediaan air di lapangan untuk mencukupi pertumbuhan tanaman padi, baik yang bersumber dari air irigasi maupun curah hujan. Berdasarkan interpretasi citra yang digunakan dan pengecekan lapangan didapatkan bahwa hasil uji akurasi menunjukkan hasil overall accuracy sebesar 88%. Nilai overall accuracy dianggap benar jika melebihi batas toleransi yang diberikan yakni ≥ 80%. Kata kunci: Kabupaten Buru, Landsat 8, lahan sawah, musim tanam, NDVI

Abstract

One of the environmental factors that affect cassava productivity is climate/weather. Climate change has the potential to have an impact on various sectors, one of which is the food crop sector. Cassava is one of the local food commodities in Ohoi Wain that is at risk of being affected by the impact of climate change. This study aimed to identify the dominant climate factors affecting cassava production, assess farmers' adaptation strategies to climate change and analyze the impact of climate change on production and farmers' income. The method used was descriptive analysis method used to analyze the dominant climate factors affecting the production of cassava and the adaptation strategy adopted by farmers, algebraic averaging technique for rainfall analysis, quantitative analysis for analyzing farmers' income and regression equations to see the relationship between rainfall and cassava productivity. The results showed that the climatic factor that most dominantly influenced the production of cassava was rainfall. The adaptation made by farmers to climate change was by changing planting time, minimum tillage, selecting superior varieties and applying organic mulch. Climate change, marked by a decrease in rainfall in 2015, caused the productivity of cassava to decrease by 46,4% and farmers' income to increase by 11,45%. The decrease in rainfall had a very significant effect on the decrease in the productivity of cassava or had a strong relationship, which was shown by the correlation coefficient value r = 0,04731 and a high level of accuracy with R2 = 89,2%. Keywords: adaptation, climate change, cassava production, income ABSTRAK Salah satu faktor lngkungan yang berpengaruh terhadap produktivitas ubi kayu adalah iklim/cuaca. Perubahan iklim berpotensi untuk memberikan dampak pada berbagai macam sektor, salah satunya adalah sektor tanaman pangan . Ubi kayu merupakan salah satu komuditas pangan lokal di Ohoi Wain yang beresiko terpengaruh dampak perubahan iklim. Penelitian ini bertujuan untuk mengidentifikasi faktor iklim yang dominan mempengaruhi produksi ubi kayu, mengkaji strategi adaptasi petani terhadap perubahan iklim dan menganalisis dampak perubahan iklim terhadap produksi dan pendapatan petani. Metode yang digunakan adalah metode analisis deskriptif, digunakan untuk menganalisis faktor iklim yang dominan mempengaruhi produksi ubi kayu dan strategi adaptasi yang dilakukan petani. Teknik rata-rata aljabar digunakan untuk analisis curah hujan, Analisis kuantitatif digunakan untuk menganalisis pendapatan petani dan persamaan regresi untuk melihat hubungan antara curah hujan dan produktivitas ubi kayu. Hasil penelitian menunjukkan bahwa faktor iklim yang paling dominan mempengaruhi produksi ubi kayu adalah curah hujan. Adaptasi yang dilakukan oleh petani terhadap perubahan iklim adalah dengan melakukan perubahan waktu tanam, pengolahan tanah minimum, pemilihan variatas unggul dan penggunaan mulsa organik. Perubahan iklim yang ditandai dengan penurunan curah hujan pada tahun 2015 menyebabkan produktivitas ubi kayu mengalami penurunan sebesar 46,4% dan pendapatan petani mengalami peningkatan sebesar 11,45%. Penurunan curah hujan berpengaruh sangat nyata terhadap penurunan produktivitas ubi kayu atau memiliki keeratan hubungan yang kuat, yang ditunjukan oleh nilai koefisien korelasi r = 0,04731 dan tingkat akurasi yang tinggi dengan R2 = 89,2%. Kata kunci: adaptasi, pendapatan, perubahan iklim, produksi ubi kayu
