Abstract

ABSTRAK. Penggerek batang merupakan masalah utama pada budidaya mangga di wilayah rendah basah. Informasimengenai hama ini masih sangat sedikit, sehingga upaya untuk mendapatkan teknologi pengendalian agak sulitdilakukan. Penelitian bertujuan untuk mengumpulkan data mengenai jenis penggerek, tingkat serangan OPT padabeberapa lokasi dan varietas mangga, serta eksplorasi untuk mendapatkan musuh alaminya. Penelitian dilakukandengan metode survai mulai Januari 2005 sampai dengan Desember 2006. Hasil penelitian menunjukkan bahwahama penggerek yang menyerang tanaman mangga di Sumatera Barat dan Sumatera Utara adalah Rhytidodera integra(Coleoptera: Cerambycidae) (Kolbe 1886). Selain didominasi jenis hama tersebut, di Kebun Percobaan Balai PenelitianTanaman Buah Tropika juga ditemukan jenis lain, yaitu spesies Palimna annulata Oliver (Coleoptera: Cerambycidae).Perilaku kedua jenis hama tersebut sama, yaitu menyerang mangga mulai dari pucuk kemudian menuju ke bagianbatang utama. Hama penggerek batang menyerang hampir semua varietas yang ditemui dan ditemukan di semuadaerah yang disurvai. Tingkat serangan rerata hama penggerek batang di Sumatera Barat 8,83% dan di Sumatera Utara10,36%. Varietas mangga yang terserang paling parah di Sumatera Barat adalah Cengkir (23,26%) dan di SumateraUtara adalah Podang (19,01%). Lima jenis agens pengendali biologi hama penggerek batang mangga ditemukanselama pelaksanaan survai. Hasil penelitian ini dapat digunakan sebagai informasi awal untuk menyusun teknologipengendalian hama penggerek batang mangga.ABSTRACT. Muryati, M. Istianto, and Affandi. 2010. Some Bioecological Aspects of Mango Stem Borer.Stem borer is the most important pest on mango in the wet lowland area. The information about this pest was stillvery limited, therefore, it is difficult to arrange its control strategy. The research were intended to collect data on thespecies of stem borer from some locations, its damage severity on some mango varieties as well as its natural enemies.The study was conducted by survey method from January 2005 to December 2006. The research revealed that thestem borer found in some locations was dominated by Rhytidodera integra (Coleoptera: Cerambycidae) (Kolbe 1886).Besides this species, another Cerambycidae, i.e. Palimna annulata Oliver was also found at Aripan Research Stationof Indonesian Tropical Fruit Research Institute. Both species have a similar behavior. The stem borer attacked almostall varieties that were found in research locations. The damage severity of mango by stem borer was 8.83 and 10.36%in West Sumatera and in North Sumatera, respectively. The most severe damage of mango variety in West Sumaterawas Cengkir (23.26%), while in North Sumatera was Podang (19.01%). Five species of natural enemies were foundduring the study. The results of this experiment can be used as initial information to control mango stem borer

Abstract

The research objective was to quantify the development and survivorship rate of S. dorsalis in different phenological stages of mango and selected weeds. The research was conducted in the laboratory of PT. Trigatra Rajasa, Mango plantation in Ketowan, Arjasa, Situbondo, East Java, Indonesia from February to September 2015. The development and survivorship rate were done through observation of life span of S. dorsalis from egg to pupa. Analysis of Variance and Duncan Multiple Range Test (p = 0.05) with 5 replications were applied to ensure the significant differences among the treatments. The result showed that development and survivorship of Scirtothrips dorsalis were supported by mango flushes and flower as well as some weeds such as Leucania leucochepala, Ipomoea triloba, Achalypha indica, Desmanthus leptophyllus and Azadirachta indica as source of food. Achalypha indica was the most suitable host with development time (12.82 ± 0.21 days) and survivorship (33 %). Weed Tridax procumbent, Momordica charantia and Mimosa pudica were unable to provide the living requirement for immature developmental stage of S. dorsalis.

Abstract

Coolant and twist drill angle is one of the factors that affect the quality of the workpiece. Coolant selection and twist drill angle are useful for reducing hole roughness and increasing drill hole precision. In addition, the coolant must be easily degraded in the environment so that the environment is not polluted. An example of coconut oil is oil that can be degraded in the environment. This study aims to determine the effect of coconut oil (CO) and drill bit angle on the hole and hole precision obtained during the drilling process. In experimental testing, conventional drilling machines are used for test testing. the tests were carried out under various machining parameters, namely spindle rotation speed of 1100 rpm, drill bit angles of 130° and 135°. Based on these parameters, the spindle rotation speed of 1100 rpm and the drill bit angle of 135° is rougher than the drilling results for the spindle rotation speed of 1100 rpm and the drill bit angle of 130°. In addition, the roundness of the drilled holes for a spindle rotational speed of 1100 rpm and a drill bit angle of 130° is more precise than the spindle rotation speed of 1100 rpm and a drill bit angle of 135°.

Abstract

Purpose—The purpose of this article is to try to look at the risk aversion determination factors that encourage the behavior of the educated workforce using or not using insurance products. The indicators used are income, education level, number of Dependents, Gender, employment status, place of residence, generation group, insurance product information Method—The analysis model used is probit regression. Primary data obtained through a survey of 111 respondents and only 93 educated workers in Aceh Province met the specifications and filled in completely. Research Results—The results show that only employment status has a positive and significant effect on labor preferences for insurance products, while other factors are not significant. Limitations — This research is still limited in samples, factors that are used as objects of research and less in-depth about the role of information affecting people's behavior. This is a suggestion for researchers to further conduct more comprehensive research. Practical Implications—The results of this study can be used as a reference for the government and companies must synergize with each other in planning insurance programs. High-income workers are expected to join insurance programs, mutual care is an important social capital to maintain the economy. The government or insurance company must increase the socialization of information on the importance of insurance programs to deal with the uncertainty of future risks.

Abstract

Fruit flies are an economic important of pest on horticultural crops. One of the commodities that are affected much due to fruit fly attack is salacca var. pondoh. The number of fruit flies attacking salacca increased from 2018 to 2021. The aims of the research was to study the population dynamics in salacca orchards in relation to climate factors and host plants. The research was conducted from July 2022 to May 2023 in salacca orchards that are members of the Salacca Farmers Association Mitra Turindo in Wonokerto, Turi, Sleman, Yogyakarta, Indonesia. The methods were counting the number of fruit flies trapped in three observation groups with different levels of sanitation and host plants around salacca orchards. Descriptive and arithmetic methods were used to determine the pattern of population oscillation among the three observation groups and differences in sanitation levels and host plants around the salacca orchards. The result showed that population fluctuations of Bactrocera spp. in salacca orchards were correlated with rainfall and relative humidity and less correlated with temperature and wind speed. Fruit fly abundance was lower in salacca orchards with better sanitation and fewer host plants around the salacca orchard.

Abstract

Fruit flies (Diptera: Tephritidae) are major pests in the horticultural sector. However, comprehensive information on their distribution across different habitats in Central Sulawesi is still lacking. This study aimed to assess the species diversity of fruit flies in three habitat types—urban, agricultural, and forest areas—in Central Sulawesi, Indonesia. Collections were conducted from November 2022 to May 2023 using Steiner traps baited with cue lure (CUE) and methyl eugenol (ME). Fruit fly specimens were identified to the species level, and diversity, dominance, and evenness indices were calculated. A total of 32 species and 10,393 individual fruit flies were collected across the three habitat types. The forest habitat exhibited the highest diversity and evenness indices, followed by agricultural and urban areas. In contrast, the urban habitat showed a higher dominance of certain species. The most dominant species were Bactrocera dorsalis (ME trap) and B. albistrigata (CUE trap). Notably, the presence of rare species found exclusively in forest habitats contributed significantly to the higher species richness observed there.

Abstract

Edible film is a thin layer that has the function of packaging or coating food that can be consumed directly with the packaged product. Edible film made from starch has the disadvantage that it is fragile and easy to use. The aim of this research is to determine the effect of glycerol concentration on the characteristics of edible film from kimpul tuber starch. The experiment was carried out using a completely randomized design (CRD), with 4 treatments with glycerol concentrations of 0.5%, 1.0%, 1.5% and 2.0%, each treatment was repeated 4 times. The results showed that the solubility, thickness, wvtr, and elongation values increased with increasing glycerol concentration used. A glycerol concentration of 2.0% produces the highest solubility value of 58.33%, thickness of 0.174mm, wvtr 33.38g/m2.hour, and elongation is found at a glycerol concentration of 1.0% with a value of 21.397%. However, on the contrary, the transparency, compressive strength, and tensile strength of edible film decrease with increasing glycerol concentration. Glycerol concentration has a significant effect on the values of solubility, thickness, transparency, compressive strength, tensile strength and elongation, but does not have a significant effect on the value of the water vapor transmission rate (WVTR). A glycerol concentration of 1% produces the best edible film with a solubility value of 38.33%, thickness of 0.125mm, transparency of 18.656%/mm, WVTR of 28.25g/m2.hour, compressive strength of 103.56N/m2, Tensile Strength of 2.9428MPa, and Elongation 21.397%.

Abstract

Undang-Undang Nomor 32 Tahun 2009 Tentang Perlindungan dan Pengelolaan Lingkungan Hidup menjadi dasar hukum yang mengatur berbagai aspek terkait dengan perlindungan dan pengelolaan lingkungan hidup khususnya terhadap pengelolaan Limbah Bahan Berbahaya dan Beracun. Di dalam Undang-Undang Nomor 32 Tahun 2009 diatur secara tegas bagaimana pengelolaan limbah B3 diatur secara tegas. Pasal 59 ayat (1) Undang-Undang Nomor 32 Tahun 2009 yang berbunyi “setiap orang yang menghasilkan limbah B3 wajib melakukan pengelolaan limbah B3 yang dihasilkannya.” Telah mengisyaratkan bahwa kegiatan yang menghasilkan limbah B3 sepenuhnya akan menjadi tanggung jawab pelaku usaha. Hal ini disebabkan dampak negatif dari limbah B3 ini sangat besar. Maka dari itu Implementasi terhadap Undang-Undang Nomor 32 Tahun 2009 Tentang Perlindungan dan Pengelolaan Lingkungan Hidup perlu di benahi dan dilaksanakan dengan baik bagi seluruh pihak terkait untuk menciptakan lingkungan hidup yang sehat dan tidak tercemar.
