Authors: Sumantra K , Wijaya I M W 
Published: November 2021

Abstract
Tourist visits to Pandawa beach in 2017-2018 experienced a very sharp increase reaching 273%. It is necessary to analyse the environment’s carrying capacity as a basis for planning and the right strategy in its management. The purpose of the study was to analyse the environmental carrying capacity of the Pandawa coast, Kutuh Village, Badung Regency and their utilisation strategies for sustainable development. The study examined the physical carrying capacity (PCC), actual carrying capacity (RCC), management capacity (MC), and adequate carrying capacity (ECC). The results showed the current number of actual visitors with an average of 3,727 visitors/day, which is still far below the physical carrying capacity, which is 20,618 visitors/day, while the actual carrying capacity is 18,864 visitors/day. So, the estimated amount visits per month that can be received is as many as 565,927 visitors/month. At the same time, the ECC value of the number of tourist visits can still be optimised by 109 visitors/day. It means that the number of officers currently available is quite capable of serving 3,727 visitors/day. The strategies to optimise the visit are the addition of facilities, tourist attractions, promotions and increasing the role of local communities in environmental preservation.
Reduction of waste generation to extend the lifetime of landfill: review

Published: November 2021

Abstract
The increasing number of people in Indonesia, one of which is the city of Semarang, has led to increased community activities. Increased community activities will affect the increase in the amount of waste production. It will also impact the service life of the landfill, so efforts need to be made to extend the service life of the landfill. Efforts can be made to reduce the amount of waste that goes to the landfill, usually by sorting organic and inorganic waste. Reducing the amount of waste can also be done by utilizing waste that has been buried in the landfill (TPA), then processed into alternative fuels or RDF (Refused Derived Fuel). Waste reduction by sorting organic and inorganic waste has been carried out in several places, namely Putri Cempo TPA, Milangsari, and Sukoharjo, with percentage reductions of 79.6%, 35%, and 58%. Meanwhile, the use of waste into fuel or RDF (Refuse Derived Fuel) can also be used as an effort to extend the service life of the landfill because waste that has been buried for a long time has a high calorific value so that it meets the requirements as fuel for the pyrolysis process.

Published: November 2021

Abstract
The Sendai Framework for Disaster Risk Reduction 2015-2030 (SFDRR) serves as the international standard for disaster risk reduction. The SFDRR places a new emphasis on risk reduction during the post-disaster recovery phase. Additionally, SFDRR encourages tangible and verifiable outcomes for catastrophe loss reduction, such as indicators for tracking progress toward seven global targets. The purpose of this article is to map the current response to the biological disaster (Covid-19) in the City of Balikpapan, Indonesia, for the Sendai Framework, using academic literature and publicly available data from governments and organizations. To provide timely responses to COVID-19 at the municipal level, this study conducted a rapid examination of newly available information from the Balikpapan government and other sources. According to the analysis’s findings, Covid 19 will have ramifications for the Sendai Framework unless the government adopts necessary legislation to keep the Sendai Framework on track. SDFRR was used to detect COVID-19 responses in Balikpapan City, although one target in the SFDRR is unclear or unidentified. Despite the fact that this goal, “Improving Disaster Preparedness for Effective Response and “Building Back Better” in Recovery, Rehabilitation, and Reconstruction,” is crucial to the Sendai Framework’s success.

Published: November 2021

AbstractWaste is one of the problems in Indonesia. Waste that is not managed correctly can lead to waste generation. One of the methods to reduce waste is the 3R System through a waste bank. However, the reality that happens in the field is that many waste banks are challenging to develop. This plan aims to plan the concept of capacity building and formulate waste bank strategies in Semarang City, especially the Banyumanik, Tembalang, and Tugu Sector. The methods used in this planning are waste sampling (SNI 19-3964-1994), recycling rate, and SWOT analysis. This planning shows the same trend that the largest inorganic waste generation in Banyumanik Sector is cardboard by 23%, in Tembalang Sector and Tugu Sector are also cardboard by 32% and 24%. For the next five years, the planned recycling rate has met 50%, namely for Banyumanik sector at 57.79%, Tembalang sector at 61.19%, and Tugu sector at 58.69%. The SWOT analysis found that there are four strategies for developing waste banks: the preparation of an organized and systematic flow of inorganic waste sales, formation of diversified activities, completeness of documents, and cooperation with third parties.

Published: November 2021

Abstract
Postmortem epidydimal preservation at low temperature (3-4°C), is a way to preserve and recover male genetic material. This effort aims for prolonging male function as sperm source, followed with its utilization in assisted reproductive technologies. This study aimed to observe the quality of sperm form cauda epididymis which preserved at low temperature for consecutive days. Sperm were retrieved from twelve cauda epididymis of Kacang Goat and its qualities namely motility, intact membrane, life/dead, and abnormality (all in %) were evaluated in every 2 days until 0% motility. Data were compared using analysis of variance at a = 0.05. Result shows significant (P<0.05) decrease in motility, intact membrane, and life/dead, but increase in abnormality during observation at day 0, day 2, day 4 and day 6, respectively. At the respective days, motility was 91.33±1.25%; 74.67±3.88%; 28.17±2.25% and 0.33±0.57%, intact membrane was 54.83±1.04%; 39±3.77%; 25.1±3.32% and 14.83±2.75%, life/dead was 55.17±4.01%; 36±3.5%; 24.3±3.25% and 12±2.78%, abnormality was 3.16±0.76%; 4.16±0.76%; 6.16±2.25% and 11±2.17%. According to the study, it is concluded that preserved sperm from cauda epididymis at low temperature shows decrease in quality and its utilization should rely on the quality status to select the most appropriate assisted reproductive technology.

Abstract
This study was aimed to analyze the genetic variation of bPRL (Bovine Prolactin) gene and its association to milk production in Indonesian Friesian Holstein (IFH) dairy cattle. In total 49 DNA from whole blood were extracted and followed with PCR-RFLP to distinguish the genotype difference between individual samples. The fragment of bPRL gene was amplified using pair of primer forward 5’-GAGTCCTTATGAGCTTGATTCTT-3’ and reverse 5’-GCCTTCCAGAAGTCGTTTGTTTTC-3’, resulting in 156 bp PCR product size. DNA digestion then performed using RsaI restriction enzyme that recognizes 5’-GT↓AC-3’ sites with blunt-end termini. According to the study, two genotypes were discovered that are AA and AB, with respective frequencies of 0.84 and 0.16. Based on the genotype grouping of milk production data, AB genotype yielded 4016.63±1344 kg while AA genotype yielded 3314.32±1153 Kg of milk per lactation. However, there is no statistical (P>0,05) difference between both genotypes on the amount of milk yielded. It is concluded that bPRL gene was not associated with milk production traits in the studied Indonesian Dairy Cattle population.

Abstract
Tropical countries such as Indonesia face high temperatures, which impact the energy utilization in poultry. This study aims to predict the egg production pattern of quail supplemented with methionine in a low-energy diet. In total, 204 laying quails were divided into two treatments: Control (T0) and 0.12% methionine supplementation (T1). After three weeks adaptation period, daily egg production data were collected for two periods of four weeks each (treatment period week 4-11). The t-test was applied to analyze the egg production data. Egg production patterns were predicted using logistic regression. The egg production pattern of T1 showed a significant increase compared to T0 during the treatment period (p<0.01) and overall period (p<0.01). Peak production from T0 and T1 was 59.14% vs. 66.82%, with a production rate of 0.22 vs. 0.18 and prediction accuracy of 91% vs. 86%, respectively. In conclusion, methionine supplementation to a low-energy diet increased egg production of quails.

Published: November 2021

Abstract
This study investigated the effect of dietary betaine supplementation and floor space on quail egg production parameters. With six replicates, four hundred fifty-six quails (21-day-old) were randomly assigned to a 2×2 factorial arrangement. The first factor was floor space of 225 cm2 (F1) and 164 cm2 (F2) by allocating 16 and 22 birds per cage (size: 3600 cm2). The second factor was dietary betaine supplementation at 0% (CON) and 0.15% (BET). Egg production was collected in 2 periods (2×28 days) starting from 43 days old. The age of the first production, 10%, 50%, and peak production, was also recorded. There is an interaction between dietary betaine supplementation and floor space on the age of productive parameters, where quails receiving betaine supplementation reached faster 50% production and peak production (p<0.05). Furthermore, the F1 group had a higher average egg production than F2 (p<0.05). BET group had a higher average egg production than CON (p<0.05). Thus, floor space 225 cm2 can be applied in the tropics provided the quails received dietary betaine supplementation.

Abstract
The study aimed to observe the effect of adding probiotic powder on the hematological status and egg production in layer-phase laying hens. This research was conducted for 30 days, located in a layer farms in Sumedang Regency, West Java. The production of probiotic powder was carried out at the Central Laboratory, Padjadjaran University. The blood was analyzed at the Multitest Commercial Laboratory, Margahayu Raya, Bandung City. The variables observed in this study were the levels of erythrocytes, leukocytes, hematocrit, and egg production in layer-phase laying hens. This study used an experimental method with statistical analysis using a completely randomized design (CRD) with four levels of probiotics (0%, 2%, 3%, 4%) and five replications. The research data were analyzed using the 0.05% Variety Print Test. The result of this research showed that the addition of probiotic powder gave the same effect on the levels of erythrocytes, leukocytes, and hematocrits of laying hens. However, probiotic powder increased egg production along with the addition of the dose of probiotic powder. It can be seen that 2%, 3% and 4% probiotic powder increased 64.1%, 41.5% and 118% egg production compared to control.

Published: November 2021

Abstract
Pasundan cattle are native Indonesian cattle located in West Java, Indonesia. These cattle have a superior trait in reproductive performance although reared in extreme environmental conditions with low-quality of feed, and resistance to parasite diseases than other cattle breeds. However, the ability to maintain Pasundan cattle genetic diversity, avoiding inbreeding, keeping the population healthy, and high reproduction efficiency are among the significant challenges currently occurred. The application of assisted reproductive technology (ART) seems promising to overcome those challenges and would impact the efficiency of genetic diversity conservation and preservation. This review aims to present the possibility to use the available ART in Pasundan cattle. The ART reviewed are the advanced technology of sperm cryopreservation, sex selection, artificial insemination, and in vitro embryo production. The sperm cryopreservation combined with sperm sexing is the most promising technology to maximize the use of genetic material of Pasundan cattle. Moreover, sexed sperm would have a promising impact on artificial insemination and/or embryo production to increase the cattle population. Furthermore, to protect genetic diversity, it is possible to apply the artificial reproductive technique and sperm or embryos conservation for genetic utilization in the future.

Abstract
Swamp buffalo has been an integral component of society in the swamp area in South Kalimantan. The system is characterized by 2-5 farmers rearing herds semi intensively in one shared kalang, a traditional wooden shelter on swamp area. This study was aimed to determine the reproductive characteristics of female swamp buffalo under kalang systems in Hulu Sungai Selatan Regency, The Province of South Kalimantan. The data of reproductive characteristics and farming systems were collected through interviewing 21 farmers in 4 kalang groups who kept 351 buffaloes (153 of them were females). The observed parameters were average of productive females ages, age at first mating, calving interval, post-partum estrus (PPE), percentages of pregnant and lactating cows. Results showed that the average of productive female buffalo ages was 9.9 ± 0.99 years; female swamp buffaloes were first mating at 51.4 months; first calving at 63.4 months; calving interval was 16.5±0.70 months; PPE was 4.9±0.64 month; gestating and lactating cows were 21.6% and 60.1%, of the productive female population, respectively. We concluded reproductive characteristics of female swamp buffalo under kalang production systems can be enhanced through improvements of the production system, including pre-weaning calf management, feed supplementation, and health care practices.

Published: November 2021

Abstract
Multiple ovulation and embryo transfer (MOET) is a reproductive technology to increase the livestock population in a short period. The success of ovary stimulation programs is influenced by an individual’s response to follicle-stimulating hormone (FSH) stimulation. In this study embryo production was carried out on local cows represented by Peranakan Ongole (PO) cows and exotic cows represented by Simmental cows. FSH stimulation was performed on 10 PO cows and 10 Simmental cows. On Day-1 Cue Mate® (progesterone) was inserted intravaginally. FSH injection (400 mg) was carried out intramuscularly from D-10 at reduced dose with 12 hours intervals (Day-10: 100 mg; Day-11: 60 mg; Day-12: 40 mg per injection). On Day-12, prostaglandin (PGF2α) was injected and Cue Mate® was removed. Artificial insemination (AI) was performed 48 hours after PGF2α injection for 3 times at 12 hours intervals. The embryo was collected 6 days after the last AI (Day-21). Superovulation response was detected on 70% of PO cows and 90% of Simmental cows. The average number of transferable embryos in Simmental cows (9.11±7.27) was higher than PO cows (7.86±7.78). This research shows that Simmental cows are more responsive to FSH stimulation, and can produce more transferable embryos than PO cows.

Abstract
The bidara plant is known as a plant that contains active ingredients and phytochemicals that have the benefit of stimulating physiological processes in the body to run well and have a healthy effect. This study aimed to determine the effect of giving bidara leaf extract on the production performance and mortality of broiler chickens. A total of 60 DOC broiler chickens were used in this study with an average body weight of 45 g which was divided into 4 treatments, including T0: control, T1: 10% bidara leaf extract, T2: 15% bidara leaf extract, T3: 20% bidara leaf extract. Each treatment was repeated 5 times with 3 research units per plot. The study was carried out experimentally in vivo using the Completely Randomized Design (CRD) research method. The data was processed by analysis of variance with the F test at the 5% level and continued with Duncan’s test. The results showed that the treatment had a significant effect (P<0.05) on production performance and mortality in broiler chickens at the 10% bidara leaf usage level. The use of bidara leaf extract can be used as a supplement in the maintenance of broiler chickens as a substitute for synthetic supplements.

Published: November 2021

Abstract
This study was conducted to determine the factors that influence farmers in using rice straw as feed for their ruminants. Primary data was obtained from a survey through face-to-face interviews involving a total of 395 farmers as respondents in Magelang Regency, Central Java, Indonesia. Farmers were selected by multistage random sampling. The data, then, were analyzed by using logistic regression. The results showed that 45.06% (178 respondents) used rice straw as feed, where only 3.37% (6 respondents) adopted the fermented straw. The type of ruminant kept by farmers, the amount of training attended, and land size affected the rice straw utilization as ruminants feed. Adopters of rice straw utilization are farmers who maintain large ruminants and tend to manage large areas of land. This finding also revealed that providing continuous training on feed technology for farmers is important. Furthermore, periodic assistance by extension workers is needed to enhance farmers in adopting the innovation of agricultural technology.

Published: November 2021

Abstract
This study was conducted to determine the effect of using complete feed containing protected soybean groats on fat-tailed lamb carcass production. A total of 9 thin-tailed lambs aged 12 months were divided into 3 groups of ration treatment: the first group only received a 100% complete feed ration (P1), the second group received a 90% complete feed ration, and 10% protected soybean groats (P2), while the third group received 80% complete feed and 20% protected soybean groats (P3). Data were analyzed using a Completely Randomized Design. Differences between treatments were further tested with Duncan’s Multiple Range Test. The results showed that complete feeds containing protected soybean groats on fat-tailed lamb carcass production had no significant effect on carcass weight, carcass percentage, carcass size, percentage of carcass size, meat weight, meat weight percentage, fleshing index, but had a significant effect on carcass production. We concluded that the use of complete feeds containing protected soybean groats increased carcass production of male fat-tailed lamb.
