Penyelenggaraan perkuliahan pada semester genap tahun ajaran 2020/2021 di Universitas Sulawesi Barat dilaksanakan secara daring untuk meminimalisir resiko penularan virus corona. Media pembelajaran daring yang dominan digunakan di Universitas Sulawesi Barat adalah eLearning UNSULBAR. Penelitian ini bertujuan untuk mengukur usability atau tingkat kebergunaan eLearning UNSULBAR studi kasus pada Prodi Pendidikan Biologi FKIP Universitas Sulawesi Barat. Pengukuran usability menggunakan USE Questionnaire yang dikembangkan oleh Arnold Lund meliputi empat aspek yaitu usefulness, ease of use, ease of learning, dan satisfaction. Data penelitian dianalisis menggunakan software SPSS dan Microsoft Excel. Hasil penelitian menunjukkan bahwa keempat aspek usability berada pada kategori sangat layak dengan usefulness (82.59%), ease of use (81.80%), ease of learning (83.46%), dan satisfaction (81,28%). Adapun hasil usability secara keseluruhan mencapai 82.11% dengan kategori sangat layak digunakan.

Honey is a natural liquid that generally has a sweet taste produced by honey bee (Apis sp.) from plant flower extract (flora nectar) or other parts of the plant (extra floral) (SNI 01-3545-2013). Bees sucked a variety of flowers and fruit juice, collected in the body, then taken to the nest and formed into honey. Honey can be used to a drug because it contains antioxidants and antimicrobials. Sweet and bitter honey were mostly produced by Apis dorsata forest bee species in the forest of Battang which now can not be cultivated properly. Characteristics of physical and chemical quality of honey vary depending on internal and external factors. Internal factors include the type of interest. External factors are like seasons, soil conditions and geographical location as well as processing and storage. Diastase enzymes, hydroxymethylfurfural (HMF), reducing sugars and moisture content, have important parameters for the quality of honey. This study aims to determine the quality of honey based on diastase enzyme activity test, HMF test, reducing sugar content and moisture content in two samples of Battang forest honey. The results showed that diastase enzyme activity 5,06 DN and hydroxymethylfurfural were not detected in honey sweet sample of Battang forest and have fulfilled honey quality requirement based on SNI 01-3545-2013. The result of moisture content analysis 22,96% and reducing sugar level 64, 91% almost reach the standard quality requirement of honey. The bitter honey sample of Battang forest, only hydroxymethylfurfural (not detected) analysis has fulfilled the quality requirement of honey based on SNI 01-3545-2013, but diastase enzyme activity <1 DN, moisture content 31,11% , and the reducing sugar content of 54,75% don't qualified based on SNI 01-3545-2013 standard.

Taman Bahari Gonda Polewali Mandar (Polman) merupakan kawasan perencanaan ekowisata bahari yang mengalami destruksi karena adanya kerusakan ekosistem mangrove. Hal ini memberi dampak negatif pada kehidupan ekosistem pesisir dan juga dampak ekonomi bagi masyarakat sekitar, sehingga menjadi urgensi untuk mengembalikan keberlangsungan ekosistem mangrove di taman bahari Gonda tersebut dengan melalui restorasi ekosistem Mangrove. Kegiatan ini bertujuan untuk meningkatkan kesadaran masyarakat tentang pentingnya mangrove dan upaya restorasinya, serta melibatkan mereka dalam kegiatan restorasi dan pengelolaan mangrove secara berkelanjutan. Metode yang digunakan dalam kegiatan ini meliputi : (1) Sosialisasi Program Kegiatan, (2) Presentasi dan Diskusi, (3) Demostrasi dan Praktek Lapangan, dan (4) Monitoring dan Evaluasi. Hasil dari kegiatan ini menunjukkan bahwa masyarakat menjadi lebih sadar akan pentingnya mangrove dan upaya restorasinya. Mereka juga mampu melakukan penanaman propagul dengan benar dan kegiatan ini juga memberikan dampak positif bagi ekonomi masyarakat, karena dapat meningkatkan potensi pariwisata dan penghasilan dari produk-produk yang dihasilkan dari mangrove

Sago extraction processing into sago flour is generally still done in a traditional or semi-mechanical way, with less attention to aspects of hygiene, and resulted sago fermentation spontaneously. This study aimed to isolate and characterize indigenous lactic acid bacteria (LAB) from sago wastewater which obtained directly from the traditional sago processing industry in Malangke Barat, South Sulawesi. The sago wastewater was stored for 1, 3 and 7 days of fermentation. The research was conducted on the LAB isolation and purification on MRS agar medium supplemented with 0.5% CaCO3. Two purified putative LAB isolate were each obtained from 1 day fermentation and 3 days fermentation. The LAB isolate from 1 day fermentation has milky white colors and smooth-round colonies, while LAB isolates from 3 days fermentation has creamy colors and smooth-round colonies. Both of the isolate were gram positive-rods, non-motile and negative catalase reaction.
