Abstract

Corn (Zea mays L.) is a potential agribusiness commodity in meeting food needs. In the national economy, corn is the second largest contributor after rice in the food subsector. One potential area for corn production is Kupang Regency which has a lot of marginal lands (dry land). This study aims to determine the factors that influence the production and technical efficiency of corn farming in Kupang Regency. This study, using the Cobb-Douglas production function method, is a functional form of the corn production function in the study area and the Stochastic Frontier method is estimated using the Ordinary Least Square (OLS) and Maximum Likelihood Estimation (MLE) methods. The results showed that all the variables in the significant model were soil, seeds, Urea, KCL, SP36, pesticides and had signs that matched expectations. The study also found that farmers were technically efficient with an average of 75 percent and factors that had a significant influence on increasing technical personnel, namely age, formal education and income.

Abstract

Penelitian ini bertujuan untuk menganalisis efisiensi saluran pemasaran biji jambu mete indikator yang digunakan yaitu pendekatan struktur, perilaku dan kinerja pasar (S-C-P) biji jambu mete didesa Lailunggi. Penentuan lokasi penelitian berdasarkan pertimbangan karena Desa Lailunggi merupakan pusat produksi jambu mete. Responden yang dijadikan sampel adalah petani, pedagang pengumpul, pedagang perantara dan pedagang besar. Pengambilan sampel responden petani dilakukan menggunakan metode simple random sampling sebanyak 40 responden petani dari total anggota populasi sebanyak 201petani. Responden pedagang tengkulak 6 orang, pedagang perantara 5 orang dan pedagang besar 6 orang jadi jumlah keseluruhan yaitu 57 responden. Dari Hasil penelitian menunjukkan bahwa pemasaran biji jambu mete di Desa Lailunggi tidak effisien. Hal ini dilihat dari harga yang diterima petani tergolong kecil pada saluran pemasaran I. pembagian harga di antara lembaga pemasaran tidak merata. struktur pasar didesa Lailunggi terbentuk pasar persaingan tidak sempurna, cenderung ke pasar monopsoni atau oligopsoni. perilaku pasar terdapat dua saluran pemasaran. Saluran pemasaran I petani- pedagang pengumpul- pedagang perantara- pedagang besar. Saluran pemasaran II petani- pedagang perantara- pedagang besar. Pada saluraan pemasaran I sebanyak 81,5% petani. Pada saluran pemasaran II sebanyak 18,4% petani. Kinerja pasar yaitu hasil analisis marjin pemasaran, saluran pemasaran I memiliki marjin sebesar Rp 500/Kg, sedangkan saluran pemasaran II sebesar Rp 1000/Kg. selanjutnya analisis farmer share tertinggi pada saluran pemasran II yaitu 95,83% dan saluran pemasaran I yaitu 92,75%.

Abstract

South Lamaknen District is the center of coffee production in Belu Regency. Coffee production is influenced by external and internal factors, H. vastatrix attacks are among the main external factors that limit coffee production in this district. Data information related to leaf rust disease in Belu district does not yet exist. Data on the distribution and severity of coffee leaf rust disease in this district do not yet exist. Such data is needed to determine appropriate control strategies to improve coffee production. The study aimed to obtain data on the severity of coffee leaf rust disease in smallholder coffee plantations in Belu Regency. The research method used was purposive random sampling (PRS) in the Belu people's coffee center in Lakmaras and Henes Villages, South Lamaknen District, with a geographical location between 9 ْ0.9' 26.61"N and 125 ْ 09' 50" LS, at an altitude between 866,7 – 1007,7 m above sea level. This study shows that coffee leaf rust disease is spread in geographical locations 9 ْ 0.9' 26.61"N and 125 ْ 09' 50" LS. The highest intensity of coffee leaf rust disease occurred in Henes village, which was 39%, while Lakmaras village was 22%. External factors affecting the incidence and severity of disease are temperature and use distance between coffee plants.

Abstract

Corn is the main commodity in dry land farming for most farmers in NTT Province and acts as a food source to maintain food security and as a source of income (cash income). Kupang Regency is one of the corn centre districts in NTT Province because it prioritises economic development in the agricultural sector in the food crop sub-sector. This study aims to measure the level of allocative efficiency of the use of corn farming production factors. This research was conducted in Kupang Timur District, Kupang Regency, East Nusa Tenggara Province in 2024. The research was conducted using a survey method with simple random sampling. The sample determined as respondents was 92 farmers based on the area of cultivated land. The method used is the calculation of marginal product analysis, used to measure allocative efficiency and economic efficiency, which is measured by the division between technical and allocative efficiency. The results of the research analysis show that the factors that have a significant effect on corn farming production are land area, seeds, urea, KCL, SP36 and Pesticides. Furthermore, from the results of the analysis of allocative and economic efficiency, the efficiency values for the overall farmer category are 0.47 and 0.35, respectively and based on the division of land area, it shows that corn farming in East Kupang District is still inefficient. Corn farming efficiency needs to be improved through the use of production factors that have a significant effect on technical efficiency, such as land area and the addition of technology. Allocative and economic efficiency of corn farming can also be improved by reducing the use of excessive inputs and expensive input prices that which can save high farming costs so that it can affect farmers' income.
