Potential and Challenges on Amphibians and Reptiles Research in West Java

West Java Province has the largest population amongst others in Java, and therefore land conversion rate in the region is increasing. Approximately 40% of forest areas in West Java has been converted between 1990–2015. As a consequence, the number of bi­odiversity in the region is decreasing, including amphibians and rep­tiles. These groups play an important role in the food chain of an ecosystem, and are very sensitive to environmental changes. How­ever, comprehensive research on amphibian and reptile species in West Java is suboptimal. Visual Encounter Survey has performed in seven districts in West Java for one month and has recorded 26 amphibian species and 27 reptile species. These species were in­cluding Javan endemic species (for example: Fejervarya iskandari, Huia masonii, Limnonectes microdiscus, Megophrys montana, and Microhyla achatina), introduced species (Calotes versicolor), and species with a new distribution record (Leptophryne borbonica and Kalophrynus minusculus). In addition, cryptic species (Genus Lep­tophryne and Cyrtodactylus), which are interesting for further stud­ies, were observed. This study has demonstrated that the potential of a comprehensive study of amphibian and reptile species in West Java is great. Apart from this, conserving the biodiversity in the region also challenging due to the high rate in land conversion

Mount Halimun Salak National Park (TNGHS) is one of the conservation areas in West Java. One of the areas in TNGHS is Cikaniki Resort which has various mushrooms. Mushroom is one of the potential biodiversity that has been developed for various purposes such as food, medicine and others. The purpose of this study was to determine the potential of mushroom and the distribution of mushroom in the cikaniki resort of Mount Halimun Salak National Park. The method was line transect. The results of this study were that there were 50 types of mushrooms, 35 mushrooms known to the name of the species and 15 unknown names of mushroom which distribution to an altitude of 1638 masl. Mushrooms were used as food producers such as, Agaricus bisporus, Auricularia polytricha, Agarics, Auricularia delicate, and Tramella fuciformis. Mushrooms were used as medicines such as Ganoderma applanatum, Laetiporus sp., And Phellinus linteus.

Geohazard Mitigation Based on Local Wisdom for Limestone Mining Site in Padalarang Area of West Java

Padalarang area of Bandung Barat Regency is famous as location of limestone mining site in West Java Province. Several geological hazards such as landslide, soil erosion and sedimentation are frequently happen in the study area. Despite the environmental damages due to geohazards, there are still many people living in this area. The objective of this paper is to reveal the efforts of disaster risk reduction based on local knowledge and wisdom of people living around the limestone quarry. Methodology in this study consists of geohazards potential mapping to delineate the area of vulnerability and mapping of the people’s knowledge and experiences in their efforts to reduce the risk of disaster around their environment. Results show that several quarries in the study area are prone to landslide and rockslide with high vulnerability. Soil erosion and sedimentation are traceable in the rivers. Native inhabitants around mining site get used to build their homes on the slope in a traditional way to avoid the danger of sliding.. Eventhough the recent home building is popular using bricks but in some cases, the traditional building is expected to be more resilient to geohazards. Stone Garden and Guha Pawon are means of keeping environmental friendly and part of geohazard mitigation.

Shear wave velocity structure beneath Bandung basin, West Java, Indonesia from ambient noise tomography

Summary We investigated the seismic shear wave velocity structure of the upper crust beneath the Bandung area in West Java, Indonesia, using ambient seismic noise tomography. We installed 60 seismographs to record ambient seismic noise continuously in the city of Bandung and its surrounding area for 8 months. After inter-station cross-correlation of recordings of ambient seismic noise, we obtained empirical Green's functions for Rayleigh waves. Group velocity dispersion curves for Rayleigh waves between periods of 1 s and 8 s were measured on each inter-station path by applying the multiple filter analysis method with phase-matched processing. The spatial variation of group velocities shows a good correlation with the geological structure of the Bandung Basin. The Rayleigh wave dispersion maps were inverted to obtain the 1D shear wave velocity profiles beneath each station, which were interpolated to infer a pseudo-3D structure under the study region. The results show that the Bandung Basin has a thick layer of sediment. Along the northern, eastern and southern mountains surrounding the Bandung Basin there is high-velocity structure, except to the west of the Tangkuban Parahu volcano, where a massive low-velocity structure extending throughout the upper crust might indicate the presence of fluids or partial melts.

Perilaku Seksual Remaja dan Pengaruh Lingkungan Sosial pada Anak-Anak Keluarga Migran dan Nonmigran

Premarital sexual behavior in adolescents is a social problem that needs attention. Premarital sexual behavior is problematic, because it is not balanced with adequate knowledge of reproductive health, so it often results in unwanted pregnancies among adolescents. The social environment is one of the factors that can be a driving factor for adolescent behavior, but on the other hand the social environment can also make behavioral changes. This article will describe adolescent sexual behavior, both for adolescents from migrant and non-migrant households in the CHAMPSEA (Child Health and Migrant Parents in South East Asia) research area in West Java and East Java. Respondents for this article are young adults with a sample of 429 adolescents from migrant and non-migrant households. The results of the study show that as many as 5.07 percent of unmarried adolescents have had premarital sexual relations, which are carried out both by adolescents from migrant and non-migrant households. Based on gender, premarital sexual behavior is more often carried out by girls than boys. While the age of first premarital sexual intercourse is mostly carried out by adolescents aged 18 years (35 percent), which is different from their perceptions of the age of marriage. Whereas based on the social environment of adolescents, there are 28.74 percent of respondents who have friends who have premarital sexual relations, have premarital sexual relations.

Influence of Motivation, Internal Control Structure and Women Economic Empowerment on Poverty Reduction Implication on Improvement of Productivity

Poverty is a global problem, often linked to needs, difficulties and shortcomings in many circumstances. Some people may understand this term subjective and comparative, while others see it in terms of moral and evaluative, and others understand it from a scientific point of view [1-4]. This poverty problem always accompanies the development process undertaken by each country. Poverty is a major problem facing developing countries including Indonesia. As a multi dimensional social phenomenon, poverty not only deals with economic dimensions but also deals with structural, psychological, cultural, ecological and other factors. The number of poor people is likely to increase, and it is undeniable that most victims of poverty are women and children [5-8]. There are still many women experiencing discrimination in various aspects of social, cultural as well as economic. Village women are particularly vulnerable Women need to be involved in planning, implementing activities, and evaluating and analyzing the impact of development. Nevertheless, the symptoms of poverty still show a real figure [6-10]. Regency, Subang, Indramayu and Cirebon are the North Coast Area of West Java where coastal areas tend to be higher poverty level [11-15].

Primary Productivity of Blanakan Fishpond at Subang, West Java

Subang regency is one of the largest fisheries area in West Java, so it is important to maintain the quality of fishpond area in Blanakan, Subang. Primary productivity can be defined as the production rate of organic carbon per unit time which is the result of solar energy by green plants to be converted into chemical energy through photosynthesis. Primary productivity can be used to define the quality of an ecosystem including fishpond. The aim of this research was to measure the value of primary productivity in mangrove fishpond, determine the correlation between the primary productivity and the content of nitrate, phosphate, and chlorophyll-a, and to analyse the significance primary productivity differences among three sampling stations. The samples were collected from three sampling stations, where all of those consist of mangrove Avicennia marina vegetation. Each station was divided into two points based on different depth i.e. 0 and 1,5 meters. The measurement of primary productivity was done by light-dark bottle method, meanwhile the nitrate, phosphate and chlorophyll-a concentration by spectrophotometer method. The result showed that the value of primary productivity ranged from 39.0625 to 101.5625 mgC/m3/day with the highest value obtained at station I and the lowest value at station III. According to statistical test, there were a significant differences of primary productivity value among three sampling stations with the value is 0.003 (p < 0.05). Correlation analysis showed that primary productivity was correlated positively with chloropyll-a and negatively with nitrate and phosphate contain water.

Short Communication: Phenotypic diversity of male pelung chickens in West Java Province, Indonesia

Abstract. Asmara IY, Garnida D, Setiawan I, Partasasmita R. 2019. Short Communication: Phenotypic diversity of male pelung chickens in West Java Province, Indonesia. Biodiversitas 20: 2243-2248. Pelung chickens are indigenous chickens from Cianjur District, West Java Province, Indonesia. The male chickens have long and beautiful crowing and have a distinct body figure compared to other indigenous chickens. Chicken contests are conducted regularly as media to show singing ability and body performance of Pelung chickens. Pelung chickens raised in different areas may have different phenotypic characteristics due to keeper preferences. Also, the phenotypic characteristics of the winners of chicken contests may influence keepers to select their chickens. The objective of this study was to determine the phenotypic characteristics of male Pelung Chickens in different areas in West Java, Indonesia. Comb type, as well as the color of eye, beak, skin, plumage, and shank, were recorded in the study. Data were collected through a survey involving 160 male birds in four different districts in West Java Province including Cianjur, Sukabumi, Bandung and Garut Districts. Key informant interview was carried out to support quantitative data. The results showed a limited variation of phenotypic characteristics among male Pelung chickens. Comb type, as well as skin and plumage colors, are criteria to select male Pelung chickens. Phenotypic characteristics of contest winners are also a reference for Pelung keepers in breeding selection.

A 5 kW of cross-flow type micro hydro power plant has been designed to fulfill the need of energy in rural area in West Java. The primary data is taken on site by considering the height of water level, water flow rate, and other parameters related to topography of the location. The system is designed by two main steps of theoretical calculation and calculation-based construction. After installation on site, a maximum water flow rate of 63.7 liters/s and generator output power of 4,025 watt are smoothly reached. The expected 5 kW of generator output power is not yet obtained, due to many losses that still occur. This situation should encourage further study for more promising development.

An Application of Markov Chain for Predicting Rainfall Data at West Java using Data Mining Approach

Markov chain model is a stochastic process to determine the transition probability of a state space based on a previous state. We can use a stationary distribution of first order-Markov chain model to determine the long terms probability rainfall phenomena. A rainfall data in West Java area has a big data because we can have a large rainfall data from many cities and regencies both of in spatial and time series observations. Furthermore, in this paper, we demonstrate an application of Markov chain using a Data Mining approach to get the knowledge as a pattern for description and prediction the monthly rainfall data in wet seasons December-January-February (DJF) using Knowledge Discovery in Database (KDD) method through pre-processing, data mining process and post-processing. We simulate the monthly rainfall data from the year 1981-2017 using four-state spaces: low (0), medium (1), high (2), and very high (4). The result of Markov chain shows that the probability of occurrence rainfall phenomena for four state spaces are: low (22.62%), medium (24.86%), high (25.46%), and very high is 27.05%. It means that West Java area over the long term condition will have a very high rainfall probability.

Interpersonal Communication Among Parents and Children in Fishermen Village in Cirebon Indonesia

Communication is crucial for the fishermen community in Indonesia because most of Indonesia's territory is the ocean. Being a fisherman was one of the backbone professions, and interpersonal communication was a bridge to inherit the traditional values of fishermen who had been passed down from their parents to their children from generation to generation. With communication, the local cultural values of the fishing community would be maintained. This paper discusses interpersonal communication in the basis of Attraction Theory and Theory of Relationship Stage. The writing was reviewed qualitatively using an ethnographic communication approach in fishermen community in Cirebon area of West Java. The study was based on direct observation of fishermen community activities, in-depth interviews, and focus group discussions with community in Citemu Village. The results of the study revealed that fishermen's work was done traditionally by making wadong , as well as selling and processing sea product. These activities were communicated by parents to children to inherit the local entrepreneurial value of fishermen. Parental interpersonal communication to children was carried out on the basis of attractions through creating meaning for the similarity of family background, physical and emotional closeness, giving rewards, and involving children in various fishing activities. Parents also paid attention to children's interest in being involved in activities, even economic pressure sometimes made parents use their authority. However, togetherness and the relationship between parents and children were conducted continuously, especially when problems occured because parents still believed that the closeness and blood bonding would restore and improve the relationship. Keywords: Attraction theory, communication ethnography, fisherman, interpersonal communication, relationship stage theory.

Screening for amylolytic activity and characterization of thermophilic Actinobacteria isolated from a Geothermal Area in West Java, Indonesia

Abstract. Syafitri WA, Ningsih F, Setyaningsih PP, Rachmania MK, Sari DCAF, Yabe S, Yokota A, Oetari A, Sjamsuridzal W. 2019. Screening for amylolytic activity and characterization of thermophilic Actinobacteria isolated from a geothermal area in West Java, Indonesia. Biodiversitas 20: 1929-1938. In this study, we describe the screening for amylolytic activity of 17 thermophilic Actinobacteria isolates obtained from the soil of Cisolok geysers, a geothermal area in West Java, Indonesia. All isolates were screened for amylolytic activity by the starch-agar plate method at various temperatures. The results showed that all of isolates were able to grow at 45oC. The growth abilities of the isolates grown in ISP 1 medium varied at temperatures from 45 to 60oC. Fifteen of the 17 isolates showed amylolytic activity at 45oC, 13 showed such activity at 50oC, and four showed activity at 55oC. Only three isolates, designated SL1-2-R-2, SL1-2-R-3, and SL1-2-R-4, showed growth and amylolytic activity at 60oC. These three isolates were selected for molecular identification. The nearly full-length of 16S rRNA gene sequences data showed that these three isolates have a similarity of 99.93-100% with Actinomadura keratinilytica WCC-2265T and of 98.74-98.91% with A. miaoliensis BC 44T-5T. Phylogenetic tree shows that all three isolates are clustered together in a monophyletic group with the type strain of A. keratinilytica WCC-2265T as their most closely related species, with 100% bootstrap support. Based on sequencing of the 16S rRNA gene, phylogenetic comparison, and phenotypic characterization, the three isolates were identified as A. keratinilytica.

Analisis Seismisitas Berdasarkan Data Gempa Bumi Periode 1958-2018 Menggunakan b-Value Pada Daerah Selatan Jawa Barat dan Banten

The area of West Java and Banten, especially is Southern is one of the areas prone to earthquakes, caused by the fact that the area is part of the ring of fire path and the presence of faults that are still active faults, such as the Cimandiri Fault, the Baribis Fault and the Lembang Fault. The purpose of this study is to determine the level of seismic activity, the fragility of the rocks and the level of the return period to make earthquake resistant buildings. The seismotechnical parameters of a region can be calculated using the Frequency-Magnitude relationship with the Guttenberg-Rithcher formulation, namely by using the Maximum Likelihood method. Based on the results of the research obtained from the combined data of USGS and BMKG, the magnitude of the 4 SR and the depths of 0-300 km. Based on the analysis and distribution of seismicity, it was found that the higher of the frequency the smaller earthquake magnitude is obtained. The results of the seismotechnical parameters provide variations of the b-value in South West Java and Banten around 0.95-1.45, with the highest value in the South of Pandeglang Regency (1.35-1.45) and the lowest in Tasikmalaya District (0.95-1.05). Variations of the a-values of an area around 6.5-9, while the highest value is in the South of Pandeglang Regency (8.5-9) and the lowest in Tasikmalaya Regency (6.5-7). The Seismicity Index is 0.632 and the Seismicity of the largest earthquakes is 0.004. Probability is at a time interval of 20 years with value as follows P (7.20) = 8%; P (7.40) = 15%; P (7.60); 21%. While variation of the return period are with variations of 5 SR = 1-4 years, 6 SR = 15-55 years and 7 SR = 150-550 years
