Hymenopteran Parasitoids

Hymenopteran parasitoids are biological control agents that contribute mortality to economically important pest of oil palm plantations. In this research we investigated the diversity and abundance of Hymenopteran parasitoids at PT. Mopoli Raya, Aceh Province, Indonesia. Data were collected by adopted a purposive sampling method in mature and immature plantations by using light trap, malaise trap, and yellow-pan trap.  Specimens were identified at Universitas Syiah Kuala and final taxonomic confirmation was conducted at Gadjah Mada University.  We found that the species richness and evenness of the Hymenoptera parasitoid species in mature oil palm plantations tended to be higher than in immature plantations.  It is suspected that in immature oil palm plants (4 years) synthetic pesticide application is more intensive and it has a negative impact on the presence of parasitoids compared to the mature.

The initial phase of the fish life cycle is a critical phase associated with high mortality due to sensitivity to predators, food availability, and also environmental changes that occur in nature. Disruption of the initial stages of fish life has a negative impact on fish populations. Until now there has been no information about fish larvae around the Banyuasin River Estuary. Therefore, research is needed on the diversity of fish larvae around the Banyuasin River Estuary, South Sumatra Province. This research were used purposive sampling method, sampling technique in the form of Cruise Track Design with continuous parallel survey trajectory. Based on the results of the study found as many as 10 families consisting of 1483 individuals of fish larvae in March and 1013 individuals of fish larvae in May consisting of Engraulidae 1,601 individuals of fish larvae, Mungiloidei as many as 109 individuals, Leiognathidae 50 individuals, Chanidae 453 individuals, Scatophagidae 20 individuals , Belonidae 39 individuals, Gobioididae 5 individuals, Chandidae 183 individuals, Syngnatihidae 6 individuals, and Gobiidae 30 individuals fish larvae. The index value of fish larvae diversity is classified as medium category (March 1.02 and May 1.12), Morisita index shows the distribution pattern of fish larvae classified as a group (March 0-14.17 and May 2.43-10.40 ), and the evenness index value is in the medium category (March 0.437 and May 0.521).

The objective of this experiment was to obtain forage/ cover crops productivity and carrying capacity for ruminant animals in Pelalawan Regency, Riau in the dry season. Data were collected from civil palm oil plantations at the aged 7, 10 and 14 years in the end of dry season with a destructive sampling method. Sampling used line intercept method which every hectare were picked 10 points by using a pair of 1 m2 sized quadrant. The result showed that the number of vegetations/ cover crops in oil palm plantations aged 7, 10 and 14 years was 42 types.The proportion of forage which consist grass, legume and ferns was diverse at each age of oil palm plantations. Forage production under oil palm plantations aged 7, 10 and 14 years were 2,571 kg/ha, 1479.76 kg/ha and 1417.22 kg/ha as fed and amounted to 811.41 kg/ ha, 471, 15 kg/ ha and 456.91 kg/ ha in the dry matter production. Average carrying capacities of oil palm plantations aged 7, 10 and 14 years was 0.36 Animal units (AU)/ha/year, 0.21 AU/ha/year and 0.20 AU/ ha/year.Penelitian ini bertujuan untuk mengetahui potensi jumlah covercrop dan kapasitas tampungnya di kebun sawit sebagai sumber pakan hijauan ruminansia pada musim kemarau di kabupaten Pelalawan, Riau.

The purposes of this study were to know marketing channel, marketing margin, share, and marketing profit of fresh fruit bunches of oil palm in Tempakan Village, Batu Engau Subregency, Paser Regency. The study was conducted from June to August 2016. The sampling method was done with two ways as random sampling in farmer level and in marketing channel as snowball sampling. Data analysis were done by calculating marketing margin, share, and marketing profit. The results of this study showed that there are two marketing channels in reserach location are channel of level zero and channel of level one. Marketing margin in farmer level was Rp40.39 kg-1 and margin in whole trader level was Rp314.44 kg-1. The average share of farmer level was 97.58% and in trader level was 81.48%. Margin and share that profitable for farmer is at channel of level zero. The average of profit in whole trader level of fresh fruit bunches was 112.75%, that meant marketing by whole trader is profitable.

The increasing of growth of any oil palm crop is not accompanied by safe behavior in the use of PPE in oil palm plantations. This is evident from most workers who do not work safely by not using PPE when they accomplished their activities. This study aims to determine of the use of Personal Protective Equipment (PPE) to workers in oil palm plantations. This is a quantitative research with cross sectional.The study population was all plantation workers totaling 77 workers and the sampling technique using total sampling method from the total total population of 77 workers. The results showed that the behavior of using PPE was in the bad category at 61.0%. Knowledge (p = 0.031), attitude (p = 0.001) and training (0.018) are variables that have a relationship with the use of PPE. Conclusions show that most workers know about the use of PPE but workers do not believe that one way to reduce the risk of workplace accidents is by using personal protective equipment and most of them have said that they have attended training in the use of personal protective equipment.

The behavior of alcohol consumption among street children is a serious health problem, because the behavior can have a negative impact. This behavior occurs due to imperfect social interaction in the community and life within the family of street children. This study aims to determine the factors that influence the behavior of alcohol consumption in street children in Kediri. This research method using quantitative approach method. The population in this study is all street children in Kediri with the criteria of adolescents ie age 10-19 years. The sample used in this study were 30 respondents, using accidental sampling method. The variables used are alcohol consumption behavior, attitude, knowledge, affordability, and peers. Data were collected using questionnaire and data analysis using Chi-square test. The results showed that of 30 street children respondents 76.7% consumed alcohol. The result of Chi-square test shows that the level factor of knowledge, attitude, affordability and environment of peers who have many opportunities to perform alcohol consumption behavior is the affordability factor with OR = 15.8. This means that the easier a person to get an alcoholic drink the greater the chance to behave alcohol consumption.
