ABSTRAK. Fenomena UHI (Urban Heat Island) mengakibatkan suhu udara perkotaan menjadi tinggi, sehingga menurunkan kualitas lingkungan kota. Untuk dapat meningkatkan kualitas kota dan mengimbangi pertumbuhan kota, maka pemerintah menggalakkan pengembangan infrastruktur hijau perkotaan melalui pengembangan Ruang Terbuka Hijau (RTH). Kota Kendari memiliki beberapa ruang terbuka yang beberapa diantaranya merupakan pusat aktifitas dan interaksi masyarakat kota, diantaranya Taman Walikota dan Pelataran Tugu Religi. Penelitian ini merupakan penelitian deskriptif untuk mengetahui kondisi iklim mikro dan kenyamanan termal ruang terbuka. Data-data yang dikumpulkan berupa karakteristik dan nilai indikator iklim mikro yang meliputi suhu udara, kelembaban relatif, dan kecepatan angin pada sejumlah titik ukur pada siang hari. Data yang dikumpulkan dianalisis menggunakan uji Statistik Independent T Test untuk mengetahui perbedaan iklim mikro antara kedua lokasi dan analisis Temperature Humidity Index (THI) untuk mengetahui tingkat kenyamanannya. Hasil dari uji statistik menunjukkan tingkat perbedaan yang tidak sigifikan antara kedua lokasi, meliputi suhu udara (sig.=0,283); kelembaban relatif (sig.=0,115); dan kecepatan angin (sig.=0,105). Sementara itu, melalui analisia THI menunjukkan nilai index tidak nyaman hampir terjadi pada keseluruhan titik ukur. Nilai THI tertinggi pada lokasi Taman Walikota terletak pada titik A5 (THI=31,9), yaitu pada daerah memiliki kecepatan angin rendah karena posisinya pada bagian tengah kawasan. Sedangkan pada lokasi pelataran Tugu Religi, nilai terendah THI diperoleh pada titik B9 (THI=33,12), yakni titik yang sebagian besar material permukaan lahannya berupa aspal. Kata kunci: ruang terbuka, temperatur, angin, kelembaban relatif, Temperature Humidity Index ABSTRACT. The UHI (Urban Heat Island) phenomenon affected urban air temperatures become high, which decreases the quality of the city environment. To be able to improve the quality of the city and to balance the growth of the city, the government promotes the development of urban green infrastructure through the development of Green Open Space (RTH). Kendari City has several open spaces, some of which are the center of the activities and interactions of urban communities, including the Taman Walikota and the Pelataran Tugu Religi. This research is a descriptive study to determine the microclimate conditions and thermal comfort of open spaces. The data collected is in the form of characteristics and values of microclimate indicators which include air temperature, relative humidity, and wind speed at some measuring points during the day. The collected data were analyzed using the Independent T-Test Statistic Test to determine the differences in microclimate between the two locations and the Temperature Humidity Index (THI) analysis to determine the level of comfort. The results of the statistical tests show a significant level of difference between the two locations, including air temperature (sig. = 0.283); relative humidity (sig. = 0.115); and wind speed (sig. = 0.105). Meanwhile, through THI analysis, the uncomfortable index value almost occurs at the whole measuring point. The highest THI value in the location of the Taman Walikota is located at point A5 (THI = 31.9), which is in the area with low wind speed because of its position in the central part of the city. Whereas in the location of the Pelataran Tugu Religi, the lowest value of THI is obtained at point B9 (THI = 33.12), which is the point where most of the surface material in the land is asphalt.

Maggot Lalat tentara hitam (Hermetia illucens) merupakan salah satu jenis insekta yang memiliki kandungan protein tinggi yang bagus digunakan sebagai pakan unggas. Tujuan dari penelitian ini adalah untuk mengoptimalkan produksi kandungan nutrisi maggot dengan penggunaan media feses ayam dengan ampas tahu. Penelitian ini dilaksanakan di mini rancs petrenakan, Universitas AL-Asyariah Mandar dan akan dilanjutkan dengan analisis nutrisi di Laboratorium Kimia Pakan Fakultas Peternakan UNHAS. Penelitian ini dirancang dengan menggunakan metode RAL dengan 4 perlakuan 3 ulangan, sehingga jumlah unit percobaan yaitu 12. P1 = ampas tahu 100% P2 = ampas tahu 50% + feses ayam 50% P3 = ampas tahu 75% + feses ayam 25% P4 = ampas tahu 25% + feses ayam 75%. Kualitas produksi nutrisi paling tinggi pada perlakuan P3 dengan kadar bahan kering 30,47%, protein kasar 42,98%, lemak kasar 34,09%, dan serat kasar 10,40%.
Bamboo is a sustainable building material because the use of new materials is sustainable. In the City of Kendari, there are still craftsmen of bamboo woven wall material. This research is important to do because to reveal how to make bamboo woven wall material by local craftsmen in Kendari and to find out the pattern of making bamboo woven wall material against the principles of sustainable architecture. This research is aimed at identifying and reviewing work tools, work materials, and how to make bamboo woven wall material against the principles of sustainable architecture by local craftsmen in Kendari City. This study uses a case study method with a qualitative approach. This study concluded that the principles of sustainable architecture in bamboo woven wall materials are as follows: working tools are used simply to reduce the use of new materials, the materials for making come from vegetation grown so that the location and natural resource ecosystems are sustainable, and how to make use of human energy so that it saves energy.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
