Abstract

Butterfly pea (Clitoria ternatea L.) is an important perennial herbaceous plant with a range of uses as ornamental plants, fodder crops, medicine, and sources of natural food colorant and antioxidants. The leaves and pods are commonly used as a source of protein in fodder, while the flowers are usually dried and processed as a high antioxidant-containing tea. The blue variant of butterfly pea was the most commonly used variety, although there are quite diverse butterfly pea varieties. The present study aimed to observe the morphological variations among the 26 butterfly pea accessions that originated from a wide range of areas in Bali. The explorative method was used to obtain diverse specimens (accessions) of butterfly pea in Bali, and subsequently, morphological characterization of the accessions was performed. The primary data of morphological traits that were recorded included stems, leaves, flower structures, flower colors, pods, and seeds. The data were analyzed descriptively to determine the morphological variations between accessions. The results showed three major morphological variations: (i) the colour of the flower (corolla), (ii) the corolla structure, and (iii) the stamen structure. The colour of corolla has four variations: white, mauve, light blue, and dark blue; while the corolla structure has two variations: normal and multiple layered corollas. The stamen character showed a correlation with the structure of the corolla. The normal corolla has diadelphous stamens, while the multiple layered corollas have solitary stamens. These morphological variations are the genetic richness of Indonesia’s biodiversity and should be protected and conserved.

Abstract

Strategy For Improving Effectiveness of Fire Care Society (MPA) in Control of Forest Fire in Bali Province. Land and forest fires seem to be an annual disaster in Indonesia. The Ministry of Environment and Forestry is initiated to form Fire Care Community Groups, called Fire Care Society (MPA). MPA in Bali has been established since 2012. The study is needed to determine the community perception who live around the forest areas, to determine the effectiveness of MPA, and to analyzed strategic increases the effectiveness of MPAregarding forest fires controlling. Research data has been collected through a closed questionnaire to compile the respond of respondents in the google form. The respondent consisted of MPA member and non-member and related stakeholders. The types of data that been collected include respondent’s perceptions, MPA participation, and implementation of Perdirjen PPI number 3, 2018. These data then analyzed with the SWOT method. The results showed that the MPA and non-MPA members have positive perception of natural factor and human behavior as a factor of forest fires. The highest value of MPA’s participation in fires-fighting is 3.71 and participation influenced by environmental factors valued at 3.84. While the implementation of Perdirjen PPI decree is 66.39%. The SWOT analysis shows the MPA in progressive strategic S-O. So this study concludes that the MPA hasn’t been fully effective. The effectiveness can be improved by providing adequate support through clear regulations, budget allocations, and increasing human resource capacity.

Abstract

With the enactment of a global agenda known as the Sustainable Development Goals (SDGs), all local governments must mainstream the environment in various government programs and policies. The mainstreaming is carried out because of the increase in anthropogenic activities which are predicted to have an impact on the existence of development and the environment. The Province of Bali has a variety of traditional wisdom that has significantly contributed greatly to environmental services and the provision of environmental services. However, increasing population growth has the potential to reduce environmental quality because of the excessive exploitation of natural resources without taking into account the sustainability of Bali's natural resource functions that have limitations. Related to this, the sensitivity and alignments of the environment that were patterned in the SDGs from various stakeholders need to be improved in an effort to build togetherness to conduct environmental management holistically.

Abstract

Changes in the function of land on the riverbanks into residential areas have triggered a large amount of organic material that enters into river water, causing river water to degradation in quality. If we ignored this, it will trigger the growth of pathogenic bacteria that endanger human life. One alternative way to overcome the degradation in river water quality due to increased organic material is using the MBBR method with bamboo as its media. This one of method that uses the growth of bacteria attached to the media to reduce the organic material content in river water. The purpose of this experiment was to determine the effect piece of bamboo media and the biggest effectiveness value of reducing BOD and COD levels in Muding Kaja tributary water with a determined of filling ratio, dissolved oxygen and detention time. The results show that the highest effectiveness using the MBBR method with bamboo media can reduce BOD level until 90,946 % with filling ratio 30% and time detention as long 5 hours and reduce COD level until 30,435 % by using filling ratio 30% and time detention for 5 hours. From this research we can conclude that MBBR method using bamboo as media affected to reduce BOD5 dan COD level. MBBR Method very efffective to reduce BOD5 level and less effective to reduce COD level in water river. Keywords: River water pollution, Moving Bed Biofilm Reactor, Bamboo media, Effectiveness

Abstract

Penelitian bertujuan untuk mengetahui pertumbuhan generatif Asystasia pada berbagai dosis dan waktu dekomposisi pupuk kotoran kambing. Penelitian menggunakan rancangan acak lengkap (RAL), pola faktorial. Faktor pertama adalah waktu dekomposisi yang terdiri dari 3 taraf, yaitu waktu dekomposisi 4 minggu, 2 minggu dan tanpa dekomposisi. Faktor kedua adalah dosis pupuk kotoran kambing dengan 4 taraf, yaitu tanpa pupuk 0 ton ha-1, 10 ton ha-1, 20 ton ha-1, dan 30 ton ha-1. Setiap kombinasi perlakuan diulang empat kali, sehingga pot yang digunakan keseluruhan adalah 48. Variabel yang diukur adalah waktu berbunga pertama kali, total produksi biji, berat biji per 100 biji, jumlah kelopak biji, dan dimensi ukuran biji (panjang, lebar dan tebal). Hasil penelitian menunjukkan bahwa tidak terjadi interaksi diantara kedua faktor pada semua variabel yang diukur. Penambahan dosis pupuk kotoran kambing sebanyak 10 ton ha-1 secara nyata memperpanjang waktu berbunga Asystasia pertama kali dibandingkan kontrol, namun demikian pengaruh waktu dekomposisi tidak menunjukkan perbedaan yang nyata. Penambahan dosis pupuk 10 to ha-1 secara nyata dapat meningkatkan jumlah produksi biji per pot, tetapi juga secara nyata menurunkan berat biji per 100 biji dibandingkan kontrol. Dimensi biji (panjang, lebar dan tebal biji) tidak dipengaruhi baik oleh dosis pupuk maupun waktu dekomposisi. Dari penelitian ini dapat disimpulkan bahwa penambahan dosis pupuk kotoran kambing 10 ton ha-1 dapat menunda waktu berbunga, meningkatkan jumlah biji, tetapi menurunkan berat biji Asystasia.

Abstract

This study aims to analyze the water quality of the Badung River based on Class II River water quality standards according to Government Regulation No. 22 of 2021, determine the water quality status, and calculate the potential pollution load of the Badung River. Water quality measurements were conducted at five sampling points. The parameters measured and observed include Temperature, Total Suspended Solids (TSS), pH, Biochemical Oxygen Demand (BOD), Chemical Oxygen Demand (COD), Dissolved Oxygen (DO), Sulfate (SO42), Nitrate (NO3), Total Phosphate (P), Oil & Grease, Total Detergent, and Total Coliform. Samples were analyzed in the laboratory for physical, chemical, and microbiological parameters. The water quality status of the Badung River was determined using the pollution index method, and the potential pollution load was calculated using the wastewater emission coefficient approach. The results showed that the water quality and status of the Badung River are classified as lightly polluted, with an average pollution index value of 3.65. The potential pollution load entering the Badung River in the domestic sector is 0.78 tons/day for BOD, 1.07 tons/day for COD, and 0.74 tons/day for TSS. Factors contributing to the lightly polluted water quality status include population density, poorly managed domestic activities (household waste), which contribute to high pollution parameter values such as BOD, COD, and TSS, and a lack of waste management infrastructure
