The performance of Balinese pigs fed with different protein levels
Full text linkThis study aims to determine the effect of feeding rations with different protein levels. This research was conducted in Nyitdah Village, Kediri District, Tabanan Regency, Bali, which lasted for 12 weeks. The design used was a completely randomized design (CRD) consisting of four treatments and four replicates. Each replicate contained one pig. The treatments were Balinese pigs fed a ration with 14% protein level (P1), Balinese pigs fed a ration with 16% protein level (P2), Balinese pigs fed a ration with 18% protein level (P3), and Balinese pigs fed a ration with 20% protein level (P4). The variables observed were performance, nutrient digestibility, and income over feed cost. The results showed that growing pigs fed different protein levels had no significant effect (P>0,05) on initial and final weights, body weight gain, ration consumption, FCR, and nutrient digestibility. It can be concluded that feeding rations with protein levels of 14% to 20% showed no significant effect on the performance of the pigs and nutrient digestibility, however, rations with 16% protein content produced the highest income over feed cost
Analysis of the contribution of porang farming branch to total farming income in Mundeh Kauh Village, West Selemadeg District, Tabanan Regency
Full text linkPorang plantation farming is the main commodity as one of the sources of regional income, as well as the prosperity of the community. The development of farming is essentially for rural oriented economic development with the goal of increasing the income of the village community and for the ultimate goal of reducing the number of poor people in rural areas, as well as being able to open new jobs. The porang plant is developed in Tabanan Regency because the land and natural conditions are suitable for the needs of porang and have the potential to be large enough to be absorbed into the export market. This research was carried out in Mundeh Kauh Village, West Selemadeg District, Tabanan Regency. Mundeh Village is one of the areas that develops the Porang commodity. The population in this study is all farmers who are members of the Porang Farmers Group "Maju Bersama" in Mundeh Kauh Village as many as 14 farmers, where the sample is determined by census, so that it is determined that the farmer sample is 14 farmers. The analysis used is quantitative, namely looking for porang farming income and its contribution to the total farming income
The effect of feeding with different energy and protein content on the carcass and body fat composition of Joper Chicken in tropical lowland regions
Full text linkThe research aims to determine the carcass and body fat composition of Joper chickens fed chicken feed with different energy and protein content in tropical lowland areas. The experiment used a Completely Randomized Design (CRD) with four treatments and six replications, each experimental unit consisting of 5 Joper chickens. The treatments in this experiment were: Joper chickens which were fed with a metabolizable energy (ME) content of 2700 kcal/kg and crude protein (CP) 14% (A), ME 2800 kcal/kg and CP 15% (B), ME 2900 kcal /kg and CP16% (C), ME 3000 kcal/kg and CP 17% (D). The results of the research showed that the slaughter weight and carcass weight of Joper chickens treated with feed C were the highest, not significantly different (P>0.05) from those treated with feed D, but those treated with feed B and A were significantly (P<0.05) lower than feed C. Commercial carcass cuts and carcass physical composition were not significantly different (P>0.05) between treatments A, B, C, and D. Fad fat and gizzard fat, mesenteric fat, and abdominal fat were lowest in feed treatment A. Feed treatments B, C, and D were significantly higher (P<0.05) than feed treatment A. It can be concluded that Joper chickens were fed with an energy content of 2900 kcal/kg crude protein 16% (C), ME 3000 kcal/kg and crude protein 17% (D) higher than fed with an energy content of 2700 kcal/kg and crude protein (CP) 14% (A), energy 2800 kcal/kg and crude protein 15% (B). Feed treatment A produced the lowest body fat composition, which was significantly different (P<0.05) compared to treatments B, C, and D
Analysis of income and risk of Porang farming
Full text linkThis research data analyzed quantitatively to find the amount of income and risk of farming. The research was conducted in Mundeh Kauh Village, West Selemadeg District, Tabanan Regency and Depeha Village, Kubu Additional District, Buleleng Regency. The samples were taken from 19 Porang farmers from members of the Maju Bersama farmer group using the saturated sampling method and 11 Porang farmers from the Bali Porang Farmers Association (P3B) using the accidental sampling method. Farming income is the difference between the farming income obtained and the total farming expenditure. Farming risk is analyzed using the coefficient of variation. The research results reveal the following. The average income of Porang farming in Bali is IDR 2,130,493.46 per production cycle with an average plant population of 2,155 plants. The risk of Porang farming is classified as a large risk as indicated by the coefficient of variation (CV) value of Porang farming income of 1.96 (>0.5). The source of risk in Porang farming is the high variation in production due to exposure to tuber caterpillar attacks and falling prices due to the closure of Indonesian Porang exports due to non-fulfillment of food safety requirements in importing countries
The motivation of farmers to defend paddy fields from land conversion
Full text linkThe agricultural sector is a sector that plays a big role in terms of food availability and suitability. However, population growth and development dynamics have shifted land use which eventually poses problems. Changes in the use of agricultural land to non-agricultural can also be referred to as land conversion. Land function change or commonly referred to as land function change is a change in the function of part or all of the land area from its original function (according to plan) to other functions that have a negative impact (problem) on the environment and the potential of the land itself. Bali itself, it is not spared from the impact of land conversion. This can be seen from year to year the land area in Bali continues to decline, this is due to the rapid growth of the tourism sector in Bali. Gianyar Regency is one of the regions in Bali Province whose tourism development is very rapid, one of which is Ubud District, Gianyar Regency which is a tourism center area that causes the surrounding area to be affected by land conversion. Pejeng Village, which is one of the villages in Tampaksiring District, Gianyar Regency, is affected by the rapid development of tourism in Gianyar Regency. The location of Pejeng Village, which is the border between tourism centers in Ubud, has caused many investors to hunt for productive land in this area.What is interesting here is that farmers continue to maintain their land, so it is interesting to conduct research on the motivation of farmers to defend their fields from land conversion in Pejeng Village, Tampaksiring District, Gianyar Regency

Full text linkThis research aims to determine the productivity of broilers given fermented garlic peel extract (Allium sativum) through drinking water. The study used a completely randomized design (CRD) consisting of 4 treatments and 4 replicates, each consisting of 5 broilers. The treatments were drinking water without fermented garlic peel extract (P0), drinking water with 1.5% fermented garlic peel extract (P1), drinking water with 3% fermented garlic peel extract (P2), and drinking water with 4.5% fermented garlic peel extract (P3). The observed variables were performance, carcass wight, digestive tract bacteria namely Lactic Acid Bacteria (BAL), and body fat components of broilers. The results showed that broilers fed with fermented garlic peel extract at the level of 1.5%, 3.0% and 4.5% had a significant effect (P<0.05) on final weight, weight gain, FCR, slaughter weight, carcass weight, breast weight, back weight, wing weight, upper thigh weight, lower thigh weight, and Lactic Acid Bacteria population on jejenum. However, it was not significantly different (P>0.05) to the initial weight, drinking water consumption, feed consumption, carcass percentage and (thigh, back, wing, upper thigh, lower thigh percentage), and body fat
The Wastewater-contaminated treatment with heavy metals by using a sustainable green nanomaterial
Full text linkThe current research included treating wastewater with sustainable nanotechnology to remove some trace elements (arsenic, copper, baron, lead, and chromium) by using a nanomaterial extracted from potato plant waste in a sustainable, green, environmentally friendly way, with two different additions, the first adding 0.5 grams and the second adding 1 gram of nanocellulose. For two different periods (6 hours and 12 hours) for both quantities of nanocellulose. The results showed that nanocellulose has a great ability to remove the studied elements from wastewater after comparing their original concentrations that were in the water before treatment with nanocellulose. The results showed that increasing the amount of nanocellulose and increasing the time led to an increase in the removal rate, and this was clear from the results of the statistical analysis, which showed the presence of a positive significant correlation between the rate of removal of trace elements from waste water with increasing the amount of nanocellulose and increasing the time. When comparing the removal rates of the studied elements from wastewater with the PH values, it was found that the pH is the control of these rates, as the highest removal rates were at the neutral or close to acidic level, the pH between 5.5 and 7.5, and when the pH tends towards basicity (8 - 9.5) The removal rate decreased. The results also showed that the removal rate varies between the elements and this depends on the concentration of the element present in the water, its chemical composition, and the degree of its binding to the substance used for treatment

Estimation of existing and contribution of mangrove restoration by REMAJA PHE ONWJ Program to carbon stocks in coastal Karawang Regency, Indonesia
Full text linkOne of the efforts to mitigate climate change is the preservation of mangrove ecosystems because of their function as carbon storage and absorbers. The coast of Karawang Regency is a potential area for mangrove ecosystems, but information on existing carbon stocks and sequestration is not yet known, let alone the contribution of mangrove rejuvenation, including from rehabilitation seedlings. The study results show that the total carbon stock on the coast of Karawang Regency ranges from 13.75 – 56.89 MgC ha–1 or 5,799.88 – 24,003.58 MgC. This value is obtained from the contribution of three main species, namely A. marina of 4.38 – 15.38 MgC ha–1, R. apiculata of 5.80 – 24.63 MgC ha–1, and R. mucronata of 3.57 – 16.88 MgC ha–1. The carbon sequestration value (CO2-equivalent) on the coast of Karawang Regency ranges from 50.40 – 208.58 MgCO2-eq ha–1 or an overall of 21,266.23 – 88,013.14 MgCO2-eq. This value was obtained from the contribution of three main species, namely A. marina of 16.07 – 56.41 MgCO2-eq ha–1, R. apiculata of 21.25 – 90.29 MgCO2-eq ha–1, and R. mucronata of 13.08 – 61.88 MgCO2-eq ha–1. The total contribution value of stock and carbon sequestration from mangrove rejuvenation in the simulation up to 10 years of diameter growth reached 24.58 MgC year–1 and 90.14 MgCO2-eq year–1. These values are an accumulation of three categories of youth, namely the existing sapling category (7.86 MgC year–1 and 28.82 MgCO2-eq year–1), the existing seedling category (4.72 MgC year–1 and 17.32 MgCO2-eq year–1), and the seedling category (3.64 MgC year–1 and 13.33 MgCO2-eq year–1)
