Soil termites play a role asÂ a primary decomposer in natural forests. These types of termites canÂ Â be turned into residential pests as more land use to be plantations, housing, and buildings. This study analyzed the distribution of subterranean termites' reproductive caste, its identification, and environmental factors that influence the development of subterranean termites. The research methods used include distribution analysis using UV flying traps, surveys usingÂ GPS, identification of reproductive castes, and environmental factors includingÂ soilÂ nutrients,Â vegetation analysis, temperature, soil moisture, air humidity, and wind speed. The results showed that the distribution of termites is found throughout the Gunungpati Semarang area. The identification of reproductive caste/alates found was Termitidae. EnvironmentalÂ factorsÂ thatÂ affect the life of termites in the Gunungpati Semarang area December 2019-January 2020 include the temperature of 27.0-28.4 oC, the humidity of 60.2 -61.2 %, air pressure 950.5-975.0 hPa, soil pH 4.84 - 5.60 and soil moisture 29.7-34.0 %. The vegetation was dominated by the Apocynaceae, Sapindaceae, andÂ Euphorbiaceae. The highest value of diversity and vegetation index sequentially are Sekaran, Patemon, and Ngijo. It is found that the entire Gunungpati area of Semarang is a suitable habitatÂ for the growth and development of the Termitidae. The finding will help the authoritative institution to consider Gunungpati as a conservation area.

AbstractThis study seeks to understand the disaster-prevention consciousness focused on landslide, earthquake, and volcanic eruption among 22 students pursuing a major in Geography in the Social Science Faculty, Semarang State University (UNNES), Indonesia. It analyzed the students’ consciousness through short comments toward questions “What can we do?”, which focused on preventing, defending, reducing, and mitigating the impacts of the three kinds of natural disasters. The average number of the description was 5.7, and the median was 5. More than half of the students mentioned points related to “before disaster and usual life,” “after disaster and restoration,” “hardware/structural,” and “software/non-structural.” All the answers described ideas with reasons. But only four students described ideas based on educational viewpoints, indicating students’ lack of scientific viewpoints in elaborating their ideas about disaster prevention. This finding calls for improving students’ consciousness regarding disaster prevention through education.AbstrakPenelitian ini bertujuan untuk memahami kesadaran pencegahan bencana yang difokuskan pada tanah longsor, gempa bumi, dan letusan gunung berapi di antara 22 mahasiswa yang mengambil jurusan Geografi di Fakultas Ilmu Sosial, Universitas Negeri Semarang (UNNES), Indonesia. Kesadaran mahasiswa dianalisis melalui komentar singkat terhadap pertanyaan "Apa yang bisa kita lakukan?", yang difokuskan pada pencegahan, pertahanan, pengurangan, dan mitigasi dampak dari tiga jenis bencana alam tersebut. Rata-rata jumlah deskripsi adalah 5,7, dan median adalah 5. Lebih dari setengah mahasiswa menyebutkan poin-poin yang terkait dengan "sebelum bencana dan kehidupan biasa," "setelah bencana dan pemulihan," "perangkat keras/struktural," dan "perangkat lunak/non-struktural." Semua jawaban menggambarkan ide-ide dengan alasan yang mendasarinya. Namun, hanya empat mahasiswa yang menguraikan ide-ide berdasarkan sudut pandang pendidikan, yang menunjukkan kurangnya sudut pandang ilmiah dalam mengelaborasi ide-ide mereka tentang pencegahan bencana. Temuan ini menunjukkan perlunya peningkatan kesadaran mahasiswa mengenai pencegahan bencana melalui pendidikan. How to Cite: Yoshinori, F, Tuswadi, Takehiro, H, Tetsuo, I., Subekti, N. (2024).

Organic waste is the type of waste that has the largest amount in Indonesia. If not managed properly, the organic waste can cause various kinds problem. One of the technologies to overcome this is by means composting using Black Soldier Fly (BSF) larvae. BSF larvae (maggot) has a better decomposition ability compared to organisms as well as other microorganisms. The aims of this research is to determine the most effective substarte that can affect the growth of black soldier larvae and the speed of bioconversion. This research is a quantitative descriptive study with an expreslanatory design. The study uses two variables (independent and dependent). Independent variables in this study are feeding frequency and type of organic waste as substrate. The dependent variables in this study are the speed ofbioconversion and the growth of black soldier larvae. The instruments used in this study are experiment research. The primary Data was obtained from 8 different composition and kind of organic waste. The analysis used is univariate analysis of variance using the SPSS 25.0 application. Results showed that restaurant waste is the most effective waste for reduction by black soldier fly larvae because it produces larvae with the best growth and the highest bioconversion rate among other waste.

AbstractAn open environment with drainage and lush green grass around the hotel allows mosquitoes to breed. Mosquitoes from the genus Culex are one of the vectors for transmitting arboviruses and filariasis. Temephos is an active ingredient often used to control Culex quinquefasciatus and considered as environmental pollution. Therefore, it is necessary to develop environmentally friendly larvicides, such as the Bacillus thuringiensis biolarvicide. Many studies were conducted to control Aedes aegypti mosquito larvae using these microbial agents, but very little for controlling Cx. quinquefasciatus mosquito larvae. This study aims to compare the effectiveness of temephos and B. thuringiensis biolarvicides. Cx. quinquefasciatus larvae were divided into the insect sample group with temephos and the B. thuringiensis biolarvicide group at concentrations of 0.01, 0.02, and 0.03 mg/L. The number of dead larvae was calculated at 1, 2, 3, 4, 5, 6, and 24 hours. Data analysis was performed using probit analysis of lethal time (LT50 and LT90). From statistical analysis, B. thuringiensis as larvicides showed 100% mortality of mosquito larvae. B. thuringiensis biolarvicide can be used as a substitute for chemical larvicide since it is proven effective in killing Cx. quinquefasciatus mosquito larvae in 24 hours and is environmentally friendly.AbstrakLingkungan terbuka dengan sistem pembuangan dan rumput yang hijau di sekitar hotel memungkinkan nyamuk berkembang biak. Nyamuk dari genus Culex adalah salah satu vektor yang mengirimkan arbovirus dan filariasis. Temephos adalah bahan aktif yang sering digunakan untuk mengendalikan Culex quinquefasciatus dan dianggap mencemari lingkungan. Oleh karena itu, perlu untuk mengembangkan larvasida yang ramah lingkungan, seperti Bacillus thuringiensis biolarvasida. Banyak penelitian yang dilakukan untuk mengendalikan larva nyamuk Aedes aegypti menggunakan agen mikroba ini, tetapi sangat sedikit untuk mengendalikan larva nyamuk Cx. quinquefasciatus. Penelitian ini bertujuan untuk membandingkan efektivitas temephos dan B. thuringiensis biolarvasida. Larva Cx. quinquefasciatus dibagi menjadi kelompok sampel serangga dengan temephos dan kelompok B. thuringiensis biolarvasida pada konsentrasi 0,01, 0,02, dan 0,03 mg/L. Jumlah larva yang mati dihitung pada 1, 2, 3, 4, 5, 6, dan 24 jam. Analisis data dilakukan analisis waktu letal probit (LT50 dan LT90). Analisis statistik, B. thuringiensis sebagai larvasida menunjukkan 100% kematian larva nyamuk. B. thuringiensis biolarvasida dapat digunakan sebagai pengganti larvasida kimia karena terbukti efektif dalam membunuh larva nyamuk Cx. quinquefasciatus dalam waktu 24 jam dan ramah lingkungan.

Citrus are a horticultural commodity that has high economic value and tends to be liked by many people. In the Bawen area, Semarang Regency, there is a plantation that cultivates various types of orange plants. Many citrus plants have signs of pest attacks that have not yet been identified. This research aims to obtain data related to insect diversity and the level of damage caused by insect pest attacks on citrus plants. This research is an exploratory type of research, using a survey method. The research location was determined using purposive sampling by taking three fields of Siam Honey, Sumowono and Pamello oranges. Insect sampling was carried out using pitfall trap, yellow trap, direct observation and interviews. The results of the study showed that the diversity index was H' = 3.3, honey siam = 3.3, pamello orange (H' = 3.1) and sumowono siam (H' = 2.9). The similarity value of the three types of orange is 0.8 and the dominance is 0.05 (honey siamese), 0.06 (pamello) and 0.07 (sumowono). At the time of research, orange plants were in the generative phase so they could attract more insects. The level of damage due to pest attacks is classified as moderate. The conclusion of this research is that the highest species diversity value is Siam Honey, then Pamello orange and Siam Sumowono, the presence of insects is evenly distributed and no one species dominates. The benefit of this research is to obtain information regarding the diversity of insect types and the level of damage caused by insect pest attacks.
