Coffee Agro-Technopark Development Strategy in Tabanan Regency to Strengthen Agriculture and Tourism Synergism

Tabanan Regency has various superior agricultural commodities, including coffee plantations and potential tourist attractions. Tabanan’s agriculture and tourism sectors have not been fully exploited, so the two have not yet run synergistically. Planning for an agro-technopark (ATP) is expected to create a production area based on agricultural technology, livestock and natural beauty. The ATP will leverage the potential of upstream and downstream agribusiness, infrastructure, and supporting services in coffee production, processing, and marketing. The research objective was to identify the sub-system of input, process, output, and development strategy of coffee ATP in Munduk Temu, Tabanan Regency. Data collection was carried out in two stages: secondary data collection with document study methods and primary data collection in the field using observation and interview methods. Data were analyzed using SWOT and strategic priority determination using Quantitative Strategic Planning Matrix (QSPM) analysis. The results showed that coffee cultivation with an integrated system supporting coffee ATP in Muduk Temu Tabanan fulfills input, process, and output requirements. Still, the quantity and quality of each sub-system need to be improved. The strategic position of coffee ATP development is in quadrant I (SO Strategy). Strategic priorities with the highest TAS value: 1) implementing technological innovations for managing pre-harvest and post-harvest Robusta coffee to support product diversification (st5 = TAS 6.94); 2) Policies from the local government in regulation and providing assistance to Subak Abian in supporting the development of ATP Coffee (st1= TAS 6.87); 3) Implementing crop-livestock integration to optimize resource potential (st3=TAS 6.86); 4) Implementing research results and studies based on superior products (st.4 = TAS 6.62). It is necessary to strengthen the institutional synergy between Village Owned Enterprises (Bumdes) managers, Subak Abian, and tourism stakeholders in improving the agricultural sector in synergy with the tourism sector.

The Effect pf Source of Organic Materials and Application Time on Growth and Yield of Beetroot (Beta vulgaris L.) in Dry Land

Beetroot ( Beta vulgaris L.) is a horticultural plant that has many benefits that lie in tubers. Red beets are widely planted in highland areas with loose soil conditions. Currently, the expansion of land for food crops is experiencing problems due to limited productive land. The use of dry land as agricultural land has the main obstacles, namely low soil fertility, low organic matter content, and generally clay and dust-dominated soil. The application of organic matter needs to be added aiming to improve the physical properties of the soil, especially soil texture so that the soil becomes loose so that it does not hinder the tuber development process. The research was carried out from April 2020 to August 2020 at the Agro-Techno Park (ATP) Jatikerto garden. The study used a split-plot design with organic material sources as the main plot, namely B1: goat manure, B2: Azolla compost, B3: UB compost, and the time of application as subplots, namely T1: simultaneously planting, T2: 1 month before planting, and T3 : 2 months before planting. Observational data were analyzed using analysis of variance (Test F), if there was an influence between treatments, further tests were carried out using the Honest Significant Difference (BNJ) test. The results showed that the use of UB compost was better applied 1 month before planting because it produced high tuber weight per harvest plot and was more profitable. Based on the results of farming analysis, the use of UB compost with an application time of 1 month before planting is feasible to cultivate with an R/C reaching 3.67.

SIMULASI PENGUKURAN LONGSOR PADA KELERENGAN DAN KEDALAMAN BIDANG GELINCIR YANG BERBEDA

Landslide is one of the geological disasters that often occurs in Indonesia. Landslides can be caused by several factors; there are human factors and natural factors. In principle, landslides occur when the resisting force is smaller than the driving force. Landslides on a small and large scale can occur over time and have a fairly severe impact. Therefore, this study simulated the effect of slope and depth of slip surface on the duration and volume of landslides, which are simulated on two soils with different texture classes. Landslide simulations were conducted at Agro Techno Park and The Experimental Gardens Faculty of Agriculture. The simulation used eight treatments and ten replications consisting of three factors there are soil texture, slope and depth of slickenside. Landslide simulation was conducted using an acrylic box with a size of 100 cm x 50 cm x 75 cm with rain intensity 70 mm hour-1. The variables measured are landslides duration, landslides volume, soil texture and bulk density. Data analysis used an independent sample t-test. The result showed slope and slickenside have a significant effect on landslides duration and landslides volume. The greater the slope, the landslide occurs faster on landslides duration and the greater the volume of the landslide. The deeper slickenside has a longer landslides duration, but the volume of the landslide is larger. It showed that the greater slope has a smaller influence on the depth of slickenside and soil texture on the landslides duration and landslides volume.

SIMULASI PENDUGAAN LONGSOR: PENGARUH INTENSITAS HUJAN PADA TANAH DENGAN TEKSTUR DAN KANDUNGAN BAHAN ORGANIK YANG BERBEDA

Natural factors and human actions can cause landslides. Natural factors include high rainfall intensity and mountainous areas or hills with steep slopes. Human actions that can cause landslides are land conversion and inappropriate land management. This study aimed to explore the effect of rain intensity on soils with different textures and organic matter content. The landslide simulation study was conducted at the Agro Techno Park and Experimental Field, Faculty of Agriculture, Brawijaya University. This study used an acrylic box (size 100 cm x 50 cm x 75 cm) and aluminium plate as a base, which was adjusted to a slope of 50. There were eight treatment combinations consisting of three factors: soil texture (silty and clayey), rainfall intensity (70 mm hour-1 and 120 mm hour-1 ), and organic matter application (without and with organic matter application). The variables measured were landslide duration and volume. The results showed that the duration and volume of landslide materials are largerly influenced by rainfall intensity. Adding organic matter to the soil at any rainfall intensity may decrease landslide duration and volume by half compared to without organic matter application. Among the three factors examined (soil texture, organic matter application and rainfall intensity), rainfall intensity seems to be the most determining factor in landslide duration and volume.

Most areas in Indonesia have a high risk of landslides due to geological and geographical conditions. Landslide is affected by natural factors (such as slope stability) and human-made factors (such as land use). Slope stability is influenced by morphological conditions and hydrological conditions. Land use or land cover may affect surface roughness, which determines the infiltration rate into the soil. This study was an attempt to explore the influence of slope gradient and litter thickness on time required for landslides and the volume of landslides. This research was carried out in two different locations, Agro Techno Park and the Experimental Garden of the Faculty of Agriculture. The study was conducted in eight treatments, combinations of three factors, i.e. soil texture, slope gradient, and litter thickness, using ten replications. The duration required for landslides and the volume of landslides were measured. The gradient of the slope has a significant effect on the volume of landslides. An increase in slope at any litter thickness resulted in up to three times more volume. The difference in slope also has a significant effect on the time required for landslides. The clayey texture needs two times the longer time required for landslides to occur. The slope gradient has a more dominant influence than the thickness of litter and soil texture. The effect of the thickness of the litter is getting bigger; on the other hand, the effect of soil texture is getting smaller with increasing slope.

Landslide is the process of moving slope-forming material that moves out of the slope. Landslides cause adverse impacts, such as damage to residences, public facilities, death tolls, and damage to agricultural land. Factors for landslides are influenced by disturbing slope stability due to steep slopes, high rainfall intensity, and movement of soil, rock, or a mixture of both. The research was conducted at Agro Techno Park of Brawijaya University (silt loam texture soil) and the experimental field of Faculty of Agriculture Brawijaya University (clay texture soil). The landslide simulation tool used acrylic (100 cm x 50 cm x 75 cm), with an aluminum plate as a base for adjusting the slope. Artificial rain was set to be stable at an intensity of 70 mm hour-1. This study used a combination of three factors, namely soil texture (C: silt loam and J: clay); slope (L1: 40° and L2: 50°); and surface rock (B1: 25% and B2: 50%), so that there were eight treatments with ten repetitions. The landslide duration and volume were measured. The data obtained were then statistically analyzed through the normality test and the unpaired t-test. The results show that increasing slope gradient from 40° to 50° on silty loam texture with similar rock content at the soil surface resulted in 6 times faster and two times larger landslide volume. At a very steep slope, the effect of soil texture and % rocks at the surface would be smaller on landslide duration but became more significant on landslide volume. Generally, the landslide factors can be ranked from the most significant effect as follows: slope gradient, soil texture, and rocks coverage at the surface.

Landslide is a natural disaster that often occurs in Indonesia. The total of landslides from 2003 to 2018 is 363, which were caused by controlling factors and triggering factors or restraining factors. The relation between two factors (litter and rock) that cause landslide is still rarely researched. This research was carried out from September 2020 to March 2021, in Agro Techno Park Cangar and Jatimulyo Experimental Station. A simulation used an acrylic box (100 cm x 50 cm x 75 cm), with soil 20 cm thick on an aluminium plate adjusted at a slope of 50°. Rainfall intensity was set at 70 mm hour-1, using an Adjustable Water Gun (as a rainfall simulator) with a current of 2.6 amperes rotation sprayer A. There were eight combination treatments consisting of three factors. The variables measured were landslide duration and volume. Data obtained were then analyzed using an unpaired t-test. Apparently, the faster the landslide occurs, the larger the avalanche volume. Among the three factors observed (soil texture, litter and rocks at the surface), surface litter was the most determining factor for landslide duration and volume. Landslide duration and volume were far different between the two soil textural classes when there was no litter at the soil surface. In contrast, if there was 3 cm litter, landslide duration and volume were quite similar between the two soil textural classes. To a small extent, the occurrence of the rocks at the soil surface may fasten and increase landslide volume.

Study of microbial inoculants effect on the quality of corn stover silage planted in different areas in Kelantan

Corn stover silage serves as high-energy forage for the ruminant animal as it consists of a relatively high energy content, good digestibility and palatable. The microbial inoculants applied to silage will increase the good bacteria concentration, resulting in a higher lactic acid level, resulting in a quicker drop in the pH. The present study aimed to investigate microbial inoculants’ effects on the quality of corn stover silage planted in different areas in Kelantan. The samples of corn plant collected from PPK Tanah Merah and Agropark, UMK Jeli Campus. Each sample was treated with an effective microorganism (EM) as the treatment with the ratio used was 1: 1: 1»2: 4: 1, for molasses, salt, urea, water and EM. In contrast, the sample with no inoculation of EM served as the control. All samples were ensiled for 21 days to obtain complete fermentation. The chemical composition of the silage determined by proximate analysis. The pH value and physical characteristics of the silage were recorded. All collected data were subjected to analysis of variance. After 21 days, moisture (66.47% and 69.70%) and crude protein (13.8% and 21.2%) content were significantly higher (p<0.05) for both treatment samples from Agro Techno Park (AGPK) Universiti Malaysia Kelantan and Persatuan Peladang Kawasan (PPK), Jedok, Tanah Merah compared to the control. The results showed a significantly lower pH value (3.76 –3.81) (p<0.05) for samples treated with EM compared to control. All samples’ physical characteristics expressed a good ranging of quality silage as the texture was firm and not slimy with greenish-brown and yellowish-brown colour with a pleasant odour. There was no presence of mould observed for all samples except for control from AGPK. As a conclusion, the microbial inoculants applied to corn stover silage and fermented for 21 days had improved the moisture and crude protein content and decreased the contamination level, thus improved the quality of corn stover silage.
