Abstract

The use of location weights on the formation of the spatio-temporal  model contributes to the accuracy of the model formed. The location weights that are often used include uniform location weight, inverse distance, and cross-correlation normalization. The weight of the location considers the proximity between locations. For data that has a high level of variability, the use of the location weights mentioned above is less relevant. This research was conducted with the aim of obtaining a weighting method that is more suitable for data with high variability. This research was conducted using secondary data derived from 10 daily rainfall data obtained from BMKG Karangploso. The data period used was January 2008 to December 2018. The points of the rain posts studied included the rain post of the Blimbing, Karangploso, Singosari, Dau, and Wagir regions. Based on the results of the research forecasting model obtained is the GSTAR ((1), 1,2,3,12,36) -SUR model. The cross-covariance model produces a better level of accuracy in terms of lower RMSE values and higher R2 values, especially for Karangploso, Dau, and Wagir areas.

Abstract

Plant growth-promoting bacteria (PGPB) have become an important subject of research to increase maize production. The PGPB consortium should provide more benefits than single or dual inoculation. This study aimed to investigate the effect of a PGPB consortium on improving maize growth and yield. The field experiment used a split-plot design. The main plot consisted of three maize varieties (Talenta, Pertiwi-3, and Bisma), and the subplot consisted of three formulations of PGPB consortia [endophytic bacteria isolates, Acetobacter sp., cellulolytic, and ligninolytic (F1); endophytic bacteria isolates, Azospirillum sp., cellulolytic, and ligninolytic (F2); and endophytic bacteria isolates, cellulolytic, ligninolytic, Acetobacter sp., and Azospirillum sp. (F3)] and one control. PGPB consortia formulation did not influence maize growth significantly, but maize varieties did. Pertiwi-3 showed the highest value in all growth variables, followed by Bisma and Talenta, respectively. The effect of PGPB consortia formulation upon ear fresh and dry weight depends upon the maize variety, and Pertiwi-3 showed the highest value in yield variables. PGPB consortia formulation 2 was the most effective to apply for Pertiwi-3 cultivation, while PGPB consortia formulation 3 produced higher yields for Talenta and Bisma. These findings indicated that specific PGPB formula could improve the yield for specific maize varieties.

Abstract

Peningkatan produksi bawang merah dapat dilakukan dengan pemulsaaan. Mulsa plastik maupun organik yang umum diaplikasikan masih memiliki kekurangan sehingga diperlukan inovasi dengan pembuatan mulsa organik lembaran (Organic Mulch Sheet, OMS). Penelitian bertujuan mengkaji pengaruh komposisi OMS terhadap pertumbuhan dan biomassa tanaman bawang merah. Penelitian dilakukan bulan Desember 2019 sampai Februari 2020 di Lahan Percobaan UMM, Junrejo, Batu, Jawa Timur. Bahan berupa benih umbi bawang merah dan bahan baku OMS (eceng gondok, pelepah batang pisang dan sabut kelapa). Rancangan percobaan yang digunakan RAK sederhana dengan 6 perlakuan yakni 1 kontrol (tanpa mulsa) dan 5 perlakuan komposisi OMS (persentase eceng gondok (EG):pelepah batang pisang (PP): sabut kelapa (SK)) yakni M1 (40%EG: 40%PP: 20%SK), M2 (30%EG: 50%PP: 20%SK), M3 (50%EG: 40%PP: 10%SK), M4 (60%EG: 30%PP: 10%SK) dan M5 (40%EG: 50%PP: 10%SK). Data pertumbuhan dan biomassa dianalisis ANOVA, dilanjutkan dengan uji beda nyata jujur (BNJ) Tukey, dan perhitungan nilai AGR dan CGR. Komposisi OMS berbahan dasar eceng gondok, sabut kelapa dan pelepah batang pisang berpengaruh nyata terhadap tinggi tanaman, diameter batang, jumlah daun serta jumlah anakan pada akhir masa vegetatif. Aplikasi OMS meningkatkan biomassa (berat basah dan berat kering total) tanaman secara nyata pada saat panen. Perlakuan OMS yang terbuat dari 40% eceng gondok, 40% pelepah batang pisang dan 20% sabut kelapa menunjukkan pertumbuhan dan biomassa tanaman serta nilai AGR dan CGR yang lebih tinggi dibandingkan perlakuan OMS lainnya. Kata kunci: average growth rate, biodegradable, biomassa, crop growth rate

Abstract

How farmers are willing to pay bio-activators needs to bestudied. The purposes of this study are to analyze theknowledge and use of bio-activators, as well as thewillingness to pay for bio-activators in rice farming. Theresearch was conducted in Malang Regency, with a sampleof 82 farmers from Ngajum and Gondanglegi Districts. Datawere analyzed by descriptive and multiple linear regression.The results showed that the farmers are aware of one tofour brands of bio-activators, and three of the brands areused by the rice farmers. The benefits of using bioactivators that are mostly perceived by rice farmers arefertilizing the soil and plants, thereby increasing theproduction of rice farming. Willingness to pay for bioactivators is based on the prevailing market price, there isno willingness to pay a premium price. Factors that have apositive effect on willingness to pay are land area andbenefits of bio-activators. The wider the agricultural landowned by the farmer and the greater the perceived benefits,the greater the value of willingness to pay will be. Thisinformation can be taken into consideration formanufacturers of bio-activators as a new introductionbefore being released in the market.

Abstract Kaumrejo Village which is located in Malang Regency, precisely in Ngantang has the potential in the form of a durian tree which is the largest commodity produced by the Kaumrejo Village, the problem experienced by partners is how the management system and plan for making a tourist village with an attraction in the form of the original Ngantang durian are indeed become the commodity of the Kaumrejo village, besides that durian management groups have not yet been formed which will later become the main support for the tourist village, while the output targets proclaimed by our group are the first to provide social mapping of the community's carrying capacity of plans for the formation of tourist villages and the formation of groups. -the group that will indeed become the main support for the durian tourism village, it can be said later that the concept of the tourism village is community based tourism. Abstrak Desa Kaumrejo yang terletak di Kabupaten Malang, tepatnya di Ngantang memiliki potensi berupa pohon durian yang merupakan komoditi terbanyak yang dihasilkan oleh Desa Kaumrejo tersebut, permasalahan yang dialami oleh mitra adalah bagaimana system pengelolaan dan rencana pembuatan desa wisata dengan daya Tarik berupa durian asli Ngantang yang memang menjadi komoditi desa Kaumrejo tersebut, selain itu belum terbentuknya kelompok – kelompok pengelola durian yang nantinya akan menjadi penopang utama desa wisata tersebut, sementara target luaran yang dicanangkan oleh kelompok kami adalah pertama pengadaan pemetaan sosial terhadap daya dukung masyarakat akan rencana pembentukan desa wisata dan pembentukan kelompok-kelompok yang memang akan menjadi penopang utama desa wisata durian itu, bisa dikatakan nanti konsep desa wisatanya adalah community based tourism.

Abstract

Hydroponic technology is a solution to overcome the limitations of agricultural land with high production and quality. Macro and micro nutrients are elements that are useful for plant growth and development. Over-absorption of elements that contribute little to crop productivity and quality can be avoided, and fertilizer costs can be minimized by applying elements quantitatively to the nutrient solution supplied to plants. The purpose of this study was to determine the nutritional formula with macro and micro nutrients in red spinach (Amaranthus tricolor L.) with the desired plant size, so that fertilization management can be obtained. The research used several levels of nutrient concentration and circulation of water flow. At 25 hst when red spinach was harvested the nutrient concentration formula that showed the highest yield was 311 mg/l-1 nitrogen, 76 mg/l-1 phosphorus, 349 mg/l-1 potassium, 286 mg/l-1 calcium, 157 mg /l-1 magnesium, 248 mg/l-1 sulfur, 7 mg/l-1 iron, 2.9 mg/l-1 manganese, 0.6 mg/l-1 zinc, 0.6 mg/l-1 boron, 0.1 mg/l-1 copper, 0.06 mg/l-1 molybdenum. This calculation is a proper concentration to be used as a reference for sustainable hydroponic nutrient management. Keywords: nutrient concentration, red spinach, hydroponics, NFT system
