Abstract

ABSTRAKFungsi sumber mata air Senjoyo sebagai kawasan lindung resapan air dan sekitar mata air perlu mendapat prioritas untuk menjamin keberlanjutan sumber mata air Senjoyo. Keberhasilan pengelolaan sumber mata air Senjoyo sebagai kawasan lindung resapan air dan sekitar mata air dapat ditunjukkan dengan status keberlanjutan pada dimensi ekologi. Penelitian ini bertujuan untuk menganalisis status keberlanjutan sumber mata air Senjoyo pada dimensi ekologi. Status keberlanjutan ditentukan berdasarkan indeks keberlanjutan yang dirumuskan melalui metode RAP-WARES (Rapid Appraissal for Water Resources). Penelitian yang dilakukan merupakan penelitian survei dengan data primer dan sekunder yang dikonversi menjadi data kualitatif dalam bentuk skala likert sesuai atribut yang telah disusun. Hasil skoring data ke skala likert kemudian dianalisis dengan teknik Multi-Dimensional Scaling (MDS). Hasil analisis menunjukkan bahwa indeks keberlanjutan Mata Air Senjoyo pada dimensi ekologi adalah sebesar 54.78 dan termasuk dalam kriteria cukup berkelanjutan. Model MDS yang dibangun menghasilkan nilai stress dan nilai R2 berturut-turut sebesar 14,12% dan 0,948. Nilai tersebut menunjukkan bahwa keseluruhan atribut yang digunakan dapat mengkaji dengan cukup baik status keberlanjutan kawasan mata air Senjoyo dalam dimensi ekologi. Selisih Indeks Monte Carlo dan Indeks MDS adalah sebesar 0.246 yang membuktikan bahwa kesalahan dalam proses pembuatan skor untuk setiap atribut cenderung kecil, variasi dalam pemberian skor untuk setiap atribut akibat perbedaan pendapat responden relatif kecil, proses analisis yang dilakukan berulang stabil dan kesalahan dalam pemasukan dan kehilangan data dapat dihindari. Berdasarkan hasil analisis sensitivitas, terdapat dua atribut yang paling sensitif yaitu atribut perlindungan terhadap sungai dan mata air (perubahan RMS 3,50%), dan atribut aktvitas pariwisata (perubahan RMS 3,20%). Sehingga penelitian ini menyimpulkan bahwa, pengelolaan yang dilakukan masih perlu disesuaikan dengan prinsip pembangunan berkelanjutan, terutama pada aspek perlindungan terhadap sungai dan mata air dan aktivitas pariwisata. Direkomendasikan untuk lebih mengembangkan pariwisata berbentuk ekowisata daripada pariwisata massal untuk menjamin keberlanjutan Sumber Mata Air Senjoyo.  AbstractThe function of the Senjoyo springs as a water catchment protected area and around the springs needs to be prioritized to ensure the sustainability of the Senjoyo springs. The success of the of Senjoyo springs management as a water catchment protected area and around the springs can be shown by the sustainability status of the ecological dimension. This study aims to analyze the sustainability status of the Senjoyo spring on the ecological dimension. Sustainability status is determined based on the sustainability index that was formulated using the RAP-WARES (Rapid Appraissal for Water Resources) method. This research is a survey research with primary and secondary data which is converted into qualitative data in the form of a Likert scale according to the attributes compiled. The results of scoring the data to a likert scale were then analyzed using the Multi-Dimensional Scaling (MDS) technique. The results of the analysis shown that the sustainability index of Senjoyo Springs on the ecological dimension is 54.78 and is included in the criteria for being quite sustainable. Stress values and R2 values of the MDS model that was built successively are 14.12% and 0.948. This value indicates that all of the attributes that used can properly assess the sustainability status of the Senjoyo spring on the ecological dimension. The difference between the Monte Carlo Index and the MDS Index is 0.246, which proves that the error in the scoring process for each attribute, the variation in presenting scores for each attribute, and the results of the respondent's disagreement are relatively small. Also, the analysis process that is repeated is stable and errors in data entry and loss can be avoided. Based on the sensitivity analysis, there are two most sensitive attributes, namely the attribute of protection against rivers and springs (change in RMS 3.50%), and attributes of tourism activities (change in RMS 3.20%). So, the conclusion of this study is the management that carrying out still needs to be adjusted to the principles of sustainable development, especially in the aspect of protecting rivers and springs and tourism activities. It is recommended to develop tourism in the form of ecotourism instead of mass tourism to ensure the sustainability of Senjoyo Springs.

ABSTRAKPeluang peningkatan perekonomian melalui kegiatan budidaya udang masih sangat terbuka bagiIndonesia, namun harus memperhatikan aspek keberlanjutan usaha budidaya maupun lingkungan.Penelitian ini bertujuan untuk mengkaji kondisi dan potensi wilayah pesisir Kabupaten Bantulsebagai sentra budidaya tambak udang berkelanjutan di pantai selatan Indonesia. Metode yangdigunakan adalah studi kasus melalui observasi dan wawancara, serta analisis data secara deskriptif.Hasil penelitian menunjukkan bahwa kondisi tambak udang dilihat dari aspek lingkungan memilikikualitas air yang baik akibat tidak adanya pencemaran dari luar, karena kawasan tersebut bukanmerupakan wilayah industri. Namun, keberadaan tambak dikawatirankan dapat merusak lingkunganapabila tidak dikelola dengan baik. Kondisi yang ada saat ini menunjukkan bahwa pengelolaantambak masih kurang baik karena tidak adanya sistem pengolahan limbah yang berdampak padamunculnya penyakit berak putih udang pada tahun 2016. Dilihat dari aspek ekonomi, keberlanjutanterjadi karena permintaan ekspor udang yang masih sangat tinggi dan belum bisa terpenuhi. Aspeksosial menunjukkan bahwa lokasi tambak udang di wilayah penelitian menimbulkan konflik sosialdengan adanya permasalahan status kepemilikan lahan, perijinan usaha, serta benturan dengankebijakan pemerintah setempat.Kata kunci: potensi, tambak udang, pesisir Bantul, konflik, berkelanjutanABSTRACTOpportunities to increase the economy sector by shrimp ponds farming activities are still very openfor Indonesia, but must consider the aspect of the sustainability of the cultivation and theenvironment. This study aims to examine the condition and potency of thr coastal areas of BantulRegency as a center for sustainable shrimp ponds farming in the southern coast of Indonesia. Themethod used is case study through observation and interview. then data were analysed descriptively.The results showed that the condition of shrimp ponds in terms of environment has good air qualitydue to the absence of pollution from the outside, because there is not an industrial area. However,the existence of the ponds are considered to damage the environtment if not properly managed. Inaddition, the condition of pond management is still not good because there is no sewage treatmentsystem, and cause the disease berak putih in 2016. From the economic aspect, the sustainability iscaused by the great number of demand that can not to be fulfill yet. Social aspects show that locationof shrimp ponds emerge conflict by the problems of land-planting status, business licensing, andcollision with the government.Keywords: potency, shrimp farm, Bantul’s coastal, conflict, sustainability

Abstract

Most of the tidal land in the lakeside of Rawa Pening is currently used for rice farming activities. This activity is thought to have negative impacts on seasonal herbaceous wetland ecosystem in this region. The study aimed to analyze the influence paddy fields toward the seasonal herbaceous wetland ecosystems in Rawa Pening Lake through an vegetation composition and structure approach. This study is a quantitative descriptive research with field observation method. Data of vegetation was collected using line intercept transect technique in the area widely of 625 m2 for each affected and unaffected ecosystem sample. Data analysis was performed by calculating the Sorensen Similarity Index (IS), the Margalef Diversity Index (R), the Shanon-Wiener Diversity Index (H'), the Dominance Index (C), and the Evenness Index (E). The results showed that there were differences in the composition and structure of vegetation on the two ecosystem samples, seen from the value of similarity index (IS) between both of them that included in the low criteria (39.85%). The results also showed that the Shanon-Wiener Diversity Index (H') and the Margalef Diversity Index (R) on the affected ecosystem sample  (H' = 1,9834; R = 1,825) are lower when compared to the unaffected ecosystem sample (H'= 2,1297; R = 2,112). So it can be concluded that the existence of paddy fields has changed the composition and structure of vegetation and reduced the diversity of vegetation in the affected ecosystem. Based on these conclusions, it is recommended to construct a sustainable management system of paddy fields on Rawa Pening Lake's tidal land as the effort for natural ecosystems maintenance in this region, especially in the biodiversity and ecological services preservation.

Abstract

Findings of blood at the crime scene (TKP) can provide important information in criminal cases such as homicide. Blood findings at crime scenes are usually blood spots or traces of blood that can be found on various substrates. This study aims to determine the type of wall substrate and environmental conditions that have the ability to preserve blood better, prove by success rate in identifying blood type in ABO system until 336 hour of exposure. In this study, blood samples were exposed to three variations of wall substrates, namely plastered walls, plastered and painted walls, plastered and oil-painted walls; and in two different environmental conditions (indoor and outdoor). The method used to identify blood type in this study was absorption elution. First, blood samples from substrate was transferred to a gauze by NaCl 0,98%. Then a confirmation test was carried out to ensure that the gauze sample contains a blood sample. Positive results of the confirmation test were indicated by a change in the color of the sample to bluish green when it is dripped with H2O2 and Leuco Malachite Green (LMG). The positive sample was then dripped with antiserum to determine the blood type. The success of identification of blood groups was indicated by the agglutination in the samples that were dripped with antisera A, because the blood samples used in this study are group A. The results showed that the success rate of blood group identification on the three types of substrates in the indoor environment for 336 hours was 100%. Meanwhile, in the outdoor environment, only blood samples exposed to plastered wall substrate and wall paint for 264 hours could be identified for their blood type. It can be concluded that the three types of wall substrates have the same ability to preserve blood samples for up to 336 hours of exposure, but the environmental conditions that give the best percentage of successful blood group identification were in indoor conditions. For further research is recommended to focus on external environmental factors that have the most influence on the success of blood group identification in dried blood samples.

Abstract

Utilization of Turi leaves (Sesbania grandiflora) and cassava tubers (Manihot esculenta) as a protein source to replace some fish meal can be done by silage of the two ingredients. This silage fermentation process requires adding inoculum from the fermented liquid to obtain good quality silage. This study aims to determine the effect of fermented liquid on the quality of silage made from Turi leaves and cassava tubers for fish feed ingredients through parameters of Titration End Point and pH levels. The research treatment was the addition of fermented liquid for four days with a sugar content of 1% (CT4-1%) in the treatment silage (S_CT4-1%), compared to the initial silage (SA) and the negative control silage (SKN). The results showed a significant (P<0.05) addition of CT4-1% fermented liquid, namely Titration End Point S_CT4-1% a significant increase of 281.9% from 18.33 mL in SA to 70.00 mL in treatment. The pH condition significantly decreased from 5.35 in SA to 4.17 in the treatment. Titration End Point on SKN only increased by 90.9% from 18.33 mL to 35.00 mL, with pH only dropping from 5.35 to 4.31. Study concuded that CT4-1% produced excellent quality silage of Turi leaves and cassava tubers based on TAT and pH levels. This quality can increase the chance of silage of Turi leaves and cassava tubers treated with CT4-1% as a partial substitute for fish meal in fish feed manufacture.

Abstract

Gedong Songo is a National Tourism Development Area in Bandungan region with an increasing number of visitors. Previous studies found that littering and water pollution were some of the prominent problems in Gedong Songo. The lack of knowledge and awareness towards environmental management was identified as the center of the issues. A conservation effort in the form of an early environmental education targeted elementary school students was suggested to address this problem. The environmental education was performed in State Elementary School Candi 1 and Candi 3 Bandungan and was designed as a series of activities, including lectures, discussions, observations, as well as experimental activities. As a result, many students were found to be actively engaged throughout the activities and showed an improved attitude. They realized the importance of washing hands, keeping environmental hygiene, and problem-solving. Further evaluation indicated that the students had developed a better understanding of general environmental management. Therefore, it can be concluded that early environmental education can potentially transform students' knowledge and awareness about the importance of environmental conservation. Through these activities, it is expected that the obtained experiences will support the Gedong Songo environmental conservation in the future.

Abstract

This study aims to determine the effect of probiotic concentration on the density and composition of infusoria grown on banana leaf substrate (Musa paradisiaca). This research is an experimental study in a one-factor Completely Randomized Design (CRD) with five levels of treatment, namely the probiotic concentration 0 ml/l,  0,5 ml/l, 1 ml/l,  2 ml/l and 4 ml/l with 4 repetitions for each treatment. Observations were made on days 2, 4, 6, 8, 10, 12, and 14 to obtain data in the form of infusoria density, infusoria species diversity and the number of individuals per species. These data were used to determine the density, diversity index (H'), dominance index, and the composition of infusoria species in each treatment. The results showed that the concentration of probiotics had a significant effect on the density of insuffocia (sig 0.010) based on One Way ANOVA analysis. The infusoria diversity index was included in the low category in all treatments. In line with these results, the dominance index in all treatments was in the high category. The results showed that Paramecium sp dominated the composition of the infusoria at all concentrations. The probiotic concentration was 0,5ml/l; 1ml/l; stimulated the growth of Chlorococcum and was replaced by Trichocerca tenuior populations at concentrations of 2 ml/l and 4 ml/l.Keywords: Antioxidant; chromatography profil; DPPH method; white frangipaniPengaruh Konsentrasi Probiotik Terhadap Kepadatan dan Komposisi Infusoria yang Ditumbuhkan pada Substrat Daun Pisang (Musa paradisiaca)ABSTRAKPenelitian ini bertujuan untuk mengetahui pengaruh konsentrasi probiotik terhadap kepadatan dan komposisi infusoria yang ditumbuhkan pada subtrat daun pisang (Musa paradisiaca).

Abstract

COVID-19 has a low fatality rate but has developed into a pandemic due to its highly infectious nature. Nonetheless, COVID-19 fatality is increasing in patients with a history of comorbidities. Based on survey, it was concluded that the understanding of the residents of RT 02 RW 08 Dusun Rogomulyo, Semarang Regency regarding the comorbid COVID-19 was still lacking. In addition, there was the limited funds as problem among residents to carry out medical check-up regularly. Therefore, it was necessary to increase the understanding and detection of the comorbid COVID-19 presence in these community groups. This Community Service consists of four stages of activities, including survey, health education, free medical check -up, and data analysis. The free medical check-up produced the existing comorbid COVID-19 information in this community group as its activity output, namely cardiovascular disease, especially hypertension (51.1%) and cholesterol (20%). This information supports socialization activities and was able to foster understanding and awareness of citizens to better maintain their health conditions, especially related to the comorbidity of COVID-19.

Abstract

The pathogenic fungi, such as Fusarium in the rhizosphere of tomato (Solanum lycopersicum) negatively affects the yield and quality of the plant. A number of biological control agents have been used for protecting tomato plants against wilt diseases including various fungal species. The objective of this study was to evaluate the antagonism effects of Trichoderma atroviride and T. harzianum against the pathogen Fusarium sp. associated with tomato wilt. In this study, the antagonism of these Trichoderma spp. against the Fusarium sp. was tested in vitro by the dual culture technique, and the percentage inhibition of radial growth (PIRG) and the antagonism reaction (scale 1-5) were evaluated. The results showed that T. atroviride and T. harzianum led to 70.8% PIRG and scale 1 antagonism reaction, and 40.6% PIRG and scale 3 antagonism reaction against Fusarium sp. associated with tomato wilt after 7 days of incubation, respectively. These results indicate that application of T. atroviride and T. harzianum may be promising approach for biological control of Fusarium wilt of tomato and may play an important role in sustainable agriculture.

Abstract

Air yang menenuhi kriteria kualitas air yang bersih menjadi salah satu standar kualitas hidup masyarakat banyak. Akan tetapi seiring dengan berkembangnya zaman, ketersediaan air yang memenuhi kualitas sangat sulit ditemukan. Masyarakat Kecamatan Sukun yang mengakses air yang sudah terjamin bersih masih sangat minim. Penyakit diare menjadi penyakit berbasis lingkungan yang disebabkan oleh konsumsi air yang yang paling banyak terjadi di Kecamatan Sukun. Penelitian ini bertujuan untuk mengetahui keterkaitan antara kualitas air tanah dangkal dengan tingkat risiko terkena penyakit pada masyarakat di Kecamatan Sukun Kota Malang. Kualitas air tanah dianalisis dengan menggunakan metode Water Quality Index. Tingkat risiko terkena penyakit dianalisis dengan metode Quantitative Microbiological Risk Assessment. Sedangkan untuk mengetahui keterkaitannya menggunakan uji korelasi Pearson Product Moment. Hasil dari penelitian menunjukkan parameter E. coli tergolong cukup tinggi, sedangkan untuk parameter pH, TDS dan suhu tergolong dalam kategori aman. Nilai indeks kualitas air berada pada kategori cukup, baik, dan sangat baik. Tingkat risiko terkena penyakit diare pada masyarakat tergolong tinggi. Keterkaitan antara kualitas air tanah dengan tingkat risiko terkena penyakit di lokasi penelitian tergolong dalam hubungan kuat negatif. Tingkat risiko terkena penyakit diare pada masyarakat tergolong tinggi, akan tetapi fakta di lapangan menujukkan bahwa masyarakat rata-rata tidak mengalami gangguan kesehatan khususnya diare. Hal ini disebabkan karena masyarakat menerapkan perilaku hidup bersih dan sehat dengan baik.
