Abstract

Etawah grade goat is a result of grading up line between Kacang and Etawah goats, which well adapted to Indonesia’s humid tropical climate. This goat is a dual-purpose goat breed for milk and meat production. The objectives of this study were to evaluate the polymorphism of fecundity genes through the investigation of four candidate genes for prolificacy, i.e., BMP15 (exon 1), BMPR1B (exon 1), KISS1 (exon 1), and KISS1 (intron 1) and their associations with the litter size of Etawah-Grade does. The diversity of BMP15 (exon 1), BMPR1B (exon 1), KISS1 (exon 1), and KISS1 (introns 1) genes were analyzed by the PCR-RFLP technique. A total of 106 of DNA samples were collected from Etawah-Grade does at BPTU-HPT Pelaihari in Pelaihari, South Kalimantan (51 heads) and Cordero Farm in Bogor, West Java (55 heads). Genetic polymorphisms between the two Etawah-Grade groups were calculated as well as their allele and genotype frequencies and the Polymorphic Informative Content (PIC). The Kruskal-Wallis one-factor ranked analysis of variance was used to determine whether there was any effect of genotype of the fecundity genes on litter size. The polymorphic information content (PIC) estimated at BPTU-HPT Pelaihari was 0.313, whereas at Cordero farm was 0.174, and overall PIC was 0.244. There was no association between genotypes of BMP15 (exon 1), BMPR1B (exon 1), KISS1 (exon 1), and KISS1 (intron 1) genes and litter size. Results indicated that BMP15 (exon 1) and KISS1 (exon 1) genes were monomorphic. However, the other two loci showed polymorphisms. The BMPR1B (exon 1) locus had two genotypes with the frequency for CC (96.23%) and for GG (3.77%), and KISS1 (intron 1) locus had three genotypes with the frequency for TT (80.19%), AT (17.92%), and AA (1.89%).

Abstract

Revenue is an important thing for farmers, because with the income the farmers can meet the needs of the household. The higher the income then the welfare of farmers will be improved. The purpose of this research is to identify the characteristics of farmers, analyze farmers' income and factors affecting the income level of rubber farmers in Sako Suban Village. The selection of villages was done purposively but the selection of respondents was conducted by accidental sampling. The data used in the primary data were collected by using interview method. Quantitative data processing used linear regression by using a significant level of 10%. The results of the research showed that the education of the farmers was low, the average age of the farmers was 46 years, and the majority of the farmers work as rubber farmers. Rubber contributed 63% to the total revenue and the rest comes from company laborers and loggers and average farmer incomes was IDR733.389/month. Variables that affect farmers' income are rubber prices, farmers groups, and farmers experience in rubber gardening. The variables that have no significant effect on farmers' income are the education of farmers, the labor in the family, and the land area.

Abstract

Chlorophyll has long been used as a green colorant for food and non-food applications. One source of chlorophyll is suji (Dracaena angustifolia (Medik.) Roxb.) leaf. The suji leaf chlorophyll has advantages and unique characteristics compared to the other chlorophyll sources that potential to be developed as a natural colorant. However, chlorophyll is easily degraded due to enzymatic and environmental factors. During processing and storage, the chlorophyll structure changes to its derivative compounds which are no longer green. Several attempts have been done to maintain the quality of the green color and quantity of chlorophyll contained in suji leaves. The formation of metallo-chlorophyll and development of suji leaf powder colorant have not been able to match the quality and quantity of its extract. These constraints become a challenge in the development of suji leaves as a natural colorant.

Abstract

A research was conducted to study the potential of solid oil palm waste as an antibrowning and as a repellent of Aedes aegypt. The amount of oil palm waste is increasing along with the expansion of oil palm plantation. A prevention method is needed to overcome solid, liquid, and gaseous wastes of oil palm which pollute the environment. Cellulose, hemicellulose, and lignin contained in solid waste of oil palm can be anaerobically fermented naturally to produce garbage enzyme which can be used as an antibrowning and as a repellent of Aedes aegypt. Browning index and polyphenol level were tested with UV Vis spectrophotometry while repellent level was tested using Aedes aegypti mosquito and a formula applied to the skin. The result showed that the acidity level (pH) was between 3.54-3.15. The highest antibrowning properties were found in oil palm fiber (SKS) and palm oil cake (BKS) with a browning index value of 0.037 with a relative inhibition (antibrowning) of 78%. Meanwhile, the highest repellent properties toward Aedes aegypti was showed by the on palm empty fruit bunch (TKS) + oil palm fiber (SKS) with 79.76% effective rejection percentage. There fore, fermented oil palm waste has an antibrowning effect and a repellent Aedes aegypti mosquito.

Abstract

The duration of soil moisture greatly determine the sugarcane content. Until now the effect of soil moisture duration on the sucrose content have not been studied. The objective of this study was to evaluate the duration of soil moisture before harvest that determines the yield of various types of sugarcane maturity rates. The research was conducted at Village Karangploso Malang starting from July 2015-October 2016. A factorial experiment was arranged in Randomized Block Design with 3 replications. The first factor consisted of 9 duration of average of soil moisture (1.0 week; 0.5; 1.0; 1.5; 2.0; 2.5; 3.0; 3.5; and 4.0 months) before harvesting. The second factor consisted of 4 varieties/clones (Bululawang, PS 06 199, Kenthung, and PS 881). The results showed that sugar cane plants required the duration of soil moisture in the range of 1.5-4.0 months before harvesting depending on the variety/clones. Bululawang variety (late maturity), PS 06 199 (middle to late maturity), Kenthung variety (early to middle maturity), and PS 881 varieties (early maturity) each required an average of 60,23% soil moisture during 3.0-3.5 months, 70.00% for 3.0 months, 81.40% for 2.5-4.0 months, and 86.25% for 2.0-3.5 months before harvesting to obtain the optimum sucrose content.

Abstract

Fish has two chemical sensory/receptor systems that smell (olfactory) and taste (gustatory) odor that adapt to the specific substance of the environment. In general, olfactory is similar to nasal organs for human nostrils. The olfactory receptors detect chemical stimuli in the form of electrical signals. Based on the ability of fish that can respond to chemical stimuli through the sense of smell, a substance can be used to attract the attention of fish. In response to this reality, AFA (Amino Acid Fish Aggregation) can be developed as a fish collecting tool to attract fish bu using amino acid preparation that works though the sense of smell and taste of fish. The objectives of this study were to design and produce a prototype of Amino Acid Fish Aggregation (AFA), to determine the productivity of catches of raft lift net by using AFA, and to calculate the length of the weight of the catch using AFA. The data used were catch data with weights and lengths of fish catch by raft lift net using AFA. The results showed that the AFA prototype which had a size of p x l x t : 35 x 22 x 15 cm and the highest catches was found at 18.00-00.00 WIB by using AFA with raft lift net. The catches using AFA in Palabuhanratu waters amounted to 5 types of fish, namely stolephorus sp., sardinella sp., rastrelliger kanagurta, euthynnus affinis, trichiurus sp., and positive allometrics were found in rastrelliger kanagurta and anchovy, but negative allometrics were found in euthynnus affinis, sardinella sp., and trichiurus sp.

Abstract

Most of Amorphophallus muelleri seeds for corm production derives from natural production in the forest. The objective of research was to evaluate seed quality and seedling growth from natural and gibberellin (GA3)-induced flowering, and different growing media in order to develop seed production technology. The experiments were conducted at Leuwikopo Experimental Farm of Bogor Agricultural University, Bogor, Indonesia from August 2016-April 2017. A. muelleri seeds from six culture practices were compared, i.e., mother corms with natural flowering were planted in soil media, soil+rice husk charcoal, and soil+cow manure, and mother corms induced flowering using GA3 (1.000, 1.500, and 2000 ppm) were planted in soil media. Results indicated that berry size, color, seed color and size and seed germination rate were independent of seed production method, i.e., non-induction, GA3 induction, and growing media. Germination rate was >90%, and no abnormal sprouting was found. The highest seedling establishment, represented by full-expand of first leaf, was obtained from seeds of soil+rice husk charcoal media. Seedling from seeds of soil+rice husk charcoal and soil+cow manure media had larger leaves than the other treatments. Present study implies that application of rice husk charcoal or manure in the seed production of A. muelleri is important to obtain high quality seedling.

Abstract

Continuous forest and land fires in Indonesia require multi-stakeholder concerns. Further, focal point should be on the grass root actors, since they are the closest to the fires, in term of location; the understand the most about the site situations, and could be the first responders to the fire events. Those actors, also could play a role as, either protagonists or antagonists, in the fire management program, depend on their situations. Based on the above narration, this research aimed to understand roles and challenges faced by those actors at the site level. This research was conducted in August-December 2017 in three villages, in Siak District, Riau is Village Penyengat, Sungai Rawa, and Rawa Mekar Jaya. The choice of location was based on comparable different fire frequencies occured among those three villages respectively the most, moderately, and the least frequent. The method utilized in this research was actor analysis. The data were collected from primary (interviews) and secondary sources (literatures). The analysis results showed that there were too many key players, influencing actors with negative roles, and actors with improper roles in the fire management activities. De-concentrating the influences of the Central Government and MoEF, as well as derivative legislations to legalize the roles of both the National Agency for Disaster Countermeasures (NADC-BNPB) and Army, to be involved in the fire management activities are also needed to solve the problems.

Abstract

Dextran is a long chain of carbohydrate polymers synthesized by dextransucrase enzyme with sucrose as a substrate. The physical, chemical conditions, temperature, and the concentration of sucrose in the isolate bacterial growth media play an important role in dextransucrase production. This study aims to isolate and characterize the dextransucrase producing bacteria. The bacteria were isolated from sugar cane. TBT 3.2 Isolate which had the highest viscosity (1.48 cP) and crude dextran (7.87 g/L) production was selected. TBT 3.2 Isolate was identified as Paenibacillus polymyxa with 99% similar identity. The Paenibacillus polymyxa TBT 3.2 was characterized based on their ability to produce dextran and cell number. The bacteria had the optimum growth conditions on the media for producing dextran at pH 7, temperature 30°C, and concentration of 20% sucrose. The highest dextransucrase activity and the highest specific activity were obtained after 25 minutes of incubation, with the activities of 29.41 mU/mL and 0.46 U/mg. Based on the results of this study, the Paenibacillus polymyxa TBT 3.2 can be used as a dextran producing bacteria.
