This study aims to determine the effect of the addition of mealworm frass and molasses on the proximate value of white oyster mushrooms. This type of research was an experiment using a completely randomized design (CRD) consisting of four treatments with three replications each. Test parameters include water content, ash content, crude protein, crude fat and crude fiber. Proximate data on water content, ash content, crude protein, crude fat and crude fiber were analyzed using analysis of variance (ANOVA) and Tukey's follow-up test with a 95% confidence level. The results showed that treatment with frass and frass molasses had an effect on water content, ash content, crude protein, crude fat, and a decrease in fiber content. Therefore, it can be concluded that the addition of mealworm frass and molasses affects the proximate value of the resulting oyster mushrooms.Keywords: White Oyster Mushroom, Flour Caterpillar Frass, Molasses, Proximate.

Telah dilakukan identifikasi senyawa aktif dari kulit buah kakao (Theobroma cacao L.) yang berpotensi sebagai antimikroba. Ekstraksi kulit buah kakao dilakukan dengan cara maserasi menggunakan pelarut etanol 70% dan aseton : air (7:3). Kulit buah kakao yang diekstrak dengan pelarut etanol dan aseton memiliki hasil rendemen yang berbeda, etanol memperlihatkan hasil rendemen yang tinggi dibandingkan dengan pelarut aseton. Berdasarkan hasil uji fitokimia secara kualitatif menunjukkan bahwa ekstrak kulit buah kakao pada setiap perlakuan mengandung senyawa alkaloid, flavonoid, tanin dan saponin, sedangkan terpenoid hanya teridentifikasi pada ekstrak menggunakan pelarut etanol. Dari hasil penelitian ini menunjukkan bahwa ekstrak kulit buah kakao berpotensi sebagai antimikroba Kata kunci: Kulit buah kakao, Aseton, Etanol, Fungisida Nabati.

This study aims to determine the effect of microwave radiation energy on the formation of chitosan from Black soldier fly pupae (Hermetia illucens). Microwave radiation Chitin isolation from BSF pupae was demineralized (HCl 5%, 45C) and deproteinated (NaOH 4%, 45C), then the transformation of chitin into chitosan (deacetylation) was carried out using microwave radiation with different powers, namely 240 watts, 400 watts, 560 watts and 800 watts with a radiation time of 5 minutes. Determination of the degree of deacetylation is determined by observing the spectrum produced using the infrared spectrophotometer (FTIR). The results showed that the degree of chitosan deacetylation produced on average was 61% at 240 watts; 400 watts at 63%; 560 watts by 66%; and 800 watts by 72%. Based on the research results, it can be concluded that microwave radiation energy affects the formation of chitosan in this case indicating that the higher the microwave radiation energy, the higher the degree of deacetylation of chitosan produced.Abstrak: Penelitian ini bertujuan untuk mengetahui pengaruh energi radiasi gelombang mikro terhadap pembentukan kitosan dari pupa Black soldier fly (Hermetia illucens). Radiasi gelombang mikro Isolasi Kitin selongsongan pupa BSF demineralisasi (HCl 5%, 45 C) dan deproteinasi (NaOH 4%, 45 C), selanjutnya transformasi kitin menjadi kitosan (deasetilasi) dilakukan dengan menggunakan radiasi gelombang mikro dengan daya yang berbeda-beda yaitu 240 watt, 400 watt, 560 watt dan 800 watt dengan waktu radiasi selama 5 menit. Penentuan derajat deasetilasi ditentukan dengan mengamati spektrum yang dihasilkan dengan menggunakan spektrofotometer inframerah (FTIR). Hasil pengamatan menunjukkan bahwa derajat deasetilasi kitosan yang dihasilkan rata-rata yaitu pada daya 240-watt sebesar 61%; 400 watt sebesar 63%; 560 watt sebesar 66%; dan 800 watt sebesar 72%. Berdasarkan hasil penelitian, dapat disimpulkan bahwa energi radiasi gelombang mikro berpengaruh terhadap pembentukan kitosan dalam hal ini menunjukkan bahwa semakin tinggi energi radiasi gelombang mikro semakin tinggi pula derajat deasetilasi kitosan yang dihasilkan.

Sabun padat adalah sabun yang dibuat dari reaksi saponifikasi dari lemak padat dengan NaOH yang digunakan untuk membersihkan badan. Bahan baku utama dalam pembuatan sabun adalah minyak atau lemak yang diperoleh dari bahan-bahan nabati dan hewani. Salah satu minyak nabati yang dapat digunakan adalah minyak Virgin Coconut Oil (VCO) yang memiliki khasiat terhadap kesehatan kulit. Minyak zaitun juga dapat ditambahkan sebagai salah satu bahan baku dalam pembuatan sabun. Minyak zaitun memiliki manfaat sangat baik bagi kesehatan tubuh, kecantikan wajah, rambut, kulit dan untuk mengatasi berbagai masalah gangguan penyakit. Kandungan asam oleat yang tinggi pada minyak zaitun sangat bermanfaat bagi kulit. Minyak zaitun yang sudah diolah menjadi sabun dianggap sebagai obat terbaik untuk kulit kering karena membantu mengangkat sel kulit mati dan melembabkan kulit bersisik. Selain itu, minyak zaitun juga mampu mengurangi bekas luka dan mengencangkan kulit keriput. Pelatihan dilaksanakan pada bulan Desember 2022 di Desa Cikoang, Kabupaten Takalar. Metode pelaksanaan yang digunakan dibagi dalam tiga tahap, yaitu tahap persiapan, sosialisasi dan pelatihan. Hasil yang diperoleh dari pengabdian ini yaitu respon peserta cukup tinggi. Hal ini dapat dilihat dari kehadiran dan antusias mereka dalam mengikuti pelatihan. Masyarakat memiliki keterampilan tambahan dalam memanfaatkan Virgin Coconut Oil (VCO) dan minyak zaitun menjadi sabun padat.
