Abstract

Acid sulfate soils are one of the potential lands for agriculture with appropriate treatment. The main problem in these soils is the chemical properties, which is high in acidity and limited nutrients availability and Fe and Al toxicity. Amelioration techniques are needed to improve the chemical properties of the soil, which is oyster mushroom baglog waste compost. This research aims to study the effect of oyster mushroom baglog waste (OMBW) compost to soil chemical properties, also to know the best dosage which affects chemical properties. The research was conducted at the greenhouse of the Agroecotechnology Department and the Laboratory of the Soil Department, Faculty of Agriculture, Lambung Mangkurat University, Banjarbaru. The research was started from August-October 2020. One-factor completely randomized design (CRD) with five treatments and five replications was used, the b0 treatment was not OMBW compost, b1 was 5 t ha-1, b2 was 10 t ha-1, b3 was 15 t ha-1, and b4 was 20 t ha-1. The application of the OMBW compost significantly affected the soil pH and decreased soluble-Fe and Al, but did not significantly affect the Eh value at 2 WAA (Week After Application). The best concentration of dose of OMBW compost was 10 t ha-1 which improved soil pH, decreased soluble-Fe and Al.

Abstract

Arthropoda Preference Test has been carried out on Zinnia Sp. In paddy plantations (Oryza sativa L.). This study aims to determine the level of arthropod diversity in paddy cultivation areas using Zinnia sp. compared to rice without Zinnia sp. The method used is a survey method with purposive sampling which was determined intentionally. The results of the comparison of the 2 treatments showed that in the vegetative phase the number of pests, predators, and parasitoids was more without treatment than using treatment, while the generative phase used less treatment than without treatment. Indeed, from the number of species obtained, there was no signicant difference, but it was seen from the number of fewer pests and more predators with refugia plantations compared to those without refugia. This is evidenced by the comparison of rice yields obtained more with treatment than without treatment 561:429 in units of kg.

Abstract

The lotus is one of the aquatic plants that grow in the Lebak area and is widely used as food and medicine by the local community. The lotus growing environment determines its growth. The distribution of lotus plants has not been well identified. This study aims to determine the distribution of lotus mapping for environmental evaluation of lotus growing in Teluk Sinar Village, Sungai Pandan District, Hulu Sungai Utara Regency, South Kalimantan Province. The study used data collection methods with primary and secondary data survey techniques. Primary survey through delineation of lotus plant boundaries in the field. Field measurements were also carried out to identify the environmental variables of lotus growing. In addition, the interpretation of high-resolution satellite imagery and low-resolution satellite imagery for spectral analysis. The environmental variables for growing lotus include water depth, light penetration depth, water pH, and sediment pH. The results of the study revealed a map of the distribution of lotus and the growing environment of the lotus. The lotus distribution map was obtained from the results of overlaying several thematic maps, image interpretation, and field measurements using Arc View and Arc GIS software. The distribution of lotus plants can grow in an environment with a water depth of 35-121 cm, a light penetration depth of 23-100 cm, a water pH of 6.25-8.37, and a sediment pH of 3.33-4.69. The results of the Lotus Distribution Mapping and the Lotus growing environment obtained can be used as a basis for determining the potential distribution of Lotus in each region.

Abstract

The purpose of this study was to determine the optimal level of use of sago pith silage to replace rice bran in the ration on the production performance of male Peking ducks. The research treatments included: T0 = No sago pith silage (control), T1 = Use of 5% sago pith silage in the ration, T2 = Use of 10% sago pith silage in the ration, T3 = Use of 15% sago pith silage in the ration, T4 = Use of sago pith silage 20% in the ration. The experimental diet contained 16% crude protein and 3000 kcal/kg metabolizable energy. The Pekin ducks used in this experiment were 2 weeks old. The research design used was a complete randomized design using five feeding treatments, five replications, and four ducks per replication pens. The parameters measured were feed intake, weight gain, body weight, feed conversion, the percentages of carcass, giblet, and abdominal fat at 8 weeks of age. The results showed that the use of sago pith silage had no significant effect on feed consumption, weight gain, body weight, feed conversion, and the percentages of carcass and giblet. However, the use of sago pith silage increased abdominal fat. It can be concluded that the use of sago pith silage up to 20% to replace rice bran in the ration has no negative effects on the performance and carcass quality of ducks.

Abstract

About 22,000 hectares are planned to be converted to oil palm plantations by the local government. However, this area has been the source of livelihood for the Banjar people for generations. This economic-environmental services valuation was carried out using a total valuation approach. Previous studies have shown that swamps have economic benefits as a source of water for rice farming (Oryza sativa), timber (Melaleuca cajuputi), fisheries, handicraft crops (Eleocharis dulcis), and for drinking water. They also have ecological benefits in biological functions such as fish feed and breeding grounds, Galam (Melaleuca leucadendron) breeding, water storage, carbonate stocks, and biodiversity value. The total economic value was 21.3 million IDR per ha, with a ratio of the economic value of 7.15% and the value of ecosystem services (ecological) of 92.85%.
