Abstract

The decline of land quality has an impact on the decline of productivity which in turn reduces production. This kind of thing happened to rice fields in the research area of Seririt District. The objective of this study was to evaluate the rice field quality in Seririt District, Buleleng Regency, Bali Province. The study used a survey method to take soil samples, followed by laboratory analysis for each homogeneous land unit (HLU). The HLU was determined by overlapping soil type maps, slope maps, and utility maps. Parameters analysed were bulk density, texture, porosity, water content, organic C, pH, cation exchange capacity (CEC), base saturation (BS), nutrients (total N, available P, and available K), and biomass C. The results of the laboratory analysis were compared with the criteria for soil quality based on ten minimum data sets (MDS) for each HLU. The results showed that the soil quality at the study site is classified as very good in HLU I with a soil quality index (SQI) of 18. This HLU is located in Rangdu and Ringdikit villages, with an area of 125.15 ha. Good SQI was observed on HLUs II, III, IV, V, VII, and VIII, respectively, located in Banjar Asem, Lokapaksa, Pangkung Paruk, Bestala, Ume Anyar, Mayong, Joanyar, the SQI value of 22-25 is 2,321.49 ha with the limiting factors of total N, total P, texture, and bulk density. The suggested rice field management plan is the addition of organic, nitrogen, and phosphate fertilisers.

Abstract

This research aims to determine the land suitability class for secondary crops, limiting factors, improvement efforts and making land use maps. The crops evaluated included peanuts, sorghum, soybeans, corn. The research location was carried out in Gerokgak District, Buleleng Regency, Bali Province from December 2020 to February 2021. Based on the results of slope maps, soil type maps, and overlapping land use maps, 9 homogeneous lands were obtained. The research method used a survey method for land characteristics and for soil sampling, then soil analysis was carried out in the laboratory. The suitability of the land is carried out to the sub-class level, by comparing the characteristics of the assessment land with the conditions for growing existing plants. The results showed that the actual land suitability classes for maize, sorghum, soybeans, and legumes were S3 (Marginal Suitability) to N (Not Suitability); In SLH6, SLH 8, SLH 9 for maize, sorghum, soybeans, and peanuts are classified as N (Not Suitability) while in SLH 1, SLH 2, SLH 3 , SLH 4, SLH 5, SLH 7 belong to S3. General directions for land use that can be taken to increase land productivity in the research area are terracing, garden sanitation, fertilization using urea fertilizer and SP36.

Abstract

One of the efforts to increase soil productivity, fertilization efficiency and yield increase is the application of environmentally friendly fertilization technologies. The purpose of the study was to determine the the growth response and yield of mustard greens to the application of organic fertilizer, and which organic fertilizer gave the highest yield. This research was an experiment in the greenhouse of the Experimental Garden of the Faculty of Agriculture, Udayana University using polybags. The research method used a completely randomized design (CRD), with 3 treatments each with 3 levels, and repeated 4 times so that 36 treatments were obtained. The treatments given were vermicompost fertilizer (KS0 = no vermicompost, KS1 = 5 t/ha, KS2 = 10 t/ha); goat manure (KK0= without goat manure, KK1= 5 t/ha, KS2= 10 t/ha); and organic fertilizers sold on the market (K0 = without organic fertilizer application, K1 = 5 t/ha, K2 = 10 t/ha). Each polybag was filled with 2 plants so that the total plants were 72 plants. Based on the results of the study, it can be concluded that the application of organic fertilizers (compost, vermicompost and goat manure) can increase growth and yield compared to no organic fertilizer application. The application of organic fertilizer 10 tons/ha, gave the highest yield, for a plant height of 35.00 cm; number of leaves 16.25 sheets, 79.29 g, fresh weight and 67.88 g dry weight (compost fertilizer), 34.98 cm, 21.75 sheets, 84.54 g, and 69.72 g (vermicompost fertilizer) , and 35.98 cm, 25.50 sheets, 72.83 g and 61.25 g (goat manure). It is recommended that the cultivation of mustard greens can be done by providing any type of organic fertilizer because it helps growth and yield.

Abstract

Praktek mengkombinasikan pupuk kandang ayam dengan NPK merupakan kebiasaan petani kentang di desa Candikuning, Tabanan, Bali. Petani mengeluarkan biaya cukup besar rata-rata 10 Juta untuk penanaman 1 ha kentang untuk mendapatkan kotoran ayam ini. Kompos berbahan baku residu kentang akan menjadi alternatif pengganti pupuk kandang ayam. Penelitian telah dilakukan bertujuan membandingkan kebiasaan petani dengan aplikasi kompos residu kentang dan NPK terhadap perbaikan karakteristik tanah (sifat fisik, kimia dan biologi) dan pengaruhnya terhadap peningkatan hasil kentang.  Hasil percobaan laboratorium menunjukkan bahwa pemberian 100% kompos residu kentang menyebabkan peningkatan KTK, C-organik, P-tersedia dan K-tersedia dengan nyata masing-masing sebesar 170,57%; 172,62%; 69,71% dan 208,20% dibandingkan tanpa pupuk, tetapi tidak menyebabkan meningkatnya KB. Perlakuan 100% kompos residu kentang meningkatkan total jamur secara nyata dibandingkan kontrol. Perbaikan karakteristik tanah menyebabkan meningkatnya berat total umbi segar rumpun-1 maupun ha-1 masing-masing 345,39% dan 157,84% akibat pemberian 100% kompos dibandingkan tanpa pupuk. Perlakuan 100% kompos  maupun kombinasinya dengan NPK (75%, 50% dan 25%) dan kombinasi pupuk kandang ayam dengan NPK (75%, 50% dan 25%) juga nyata meningkatkan indeks panen hampir lebih dua kali lipat (200%) dibandingkan kontrol.

Abstract

Landslide is one of the disasters that often occurs in Indonesia. Bangli is one of the areas in Bali with a high potential for landslides, especially in Kintamani. This study aimed to identify the potential and vulnerability of landslides in Sukawana and Awan Villages, Kintamani District, Bangli Regency. This study used survey and scoring methods according to the Natural Disaster Center at Gadjah Mada University for the parameters that cause landslides, namely, landform, rainfall, slope, geological structure, land use, and soil type. The landslide potential in Sukawana Village is low landslide potential with an area of 71.97 ha (1.81%) in Banjar Kubusalya, a medium potential with an area of 2,198.07 ha (55.30%) in Banjar Kubusalya, Banjar Sukawana and Banjar Paketan and high potential with an area of 932.81 ha (23.47%) located in Banjar Kuum and Banjar Sukawana. Awan Village has medium potential with an area of 772.20 ha (19.43%). For areas with high vulnerability, settlements are 110.96 ha (69.97%) in Sukawana Village, and the road network is dominated by local roads along 28.82 km (34.81%), which are in Sukawana Village.
