KADAR SERAT, AKTIVITAS ANTIOKSIDAN, VISKOSITAS DAN SIFAT SENSORIS JELLY DRINK SUSU KECAMBAH KEDELAI DENGAN VARIASI KONSENTRASI DAUN CINCAU HIJAU
Soybeans have a fairly high protein content. The derivative product of soybean sprouts is soy sprouted milk. One of the product developments from soy sprouted milk is a jelly drink. This requires additional ingredients that function as jellying agents. Cyclea barbata leaves are one of the natural jellying agents, besides that green jelly is high in fiber and rich in antioxidants. The purpose of this study was to determine the effect of Cyclea barbata concentration on fiber content, antioxidant activity, viscosity, and sensory jelly drink of soy sprouted milk. This study used a single-factor Complete Randomized Design (RAL), namely the concentration of green grass grass leaves (2%,3%,4%,5%,6%). The variables analyzed were fiber content, antioxidant activity, viscosity, and sensory (hedonic quality). The results of this study showed that the concentration of Cyclea barbata leaves had a significant effect on fiber content, antioxidant activity, viscosity, and sensory (taste, color, texture), but did not have a real effect on sensory (aroma). The best treatment is at a concentration of green jelly leaves of 6% with a value of fiber content of 7.83%, antioxidant activity of 14.95%, viscosity of 4.70 mpa.s, and sensory 3.43 (close to like)
Designing and Manufacturing of Grain Dryer Machine using Coconut Shell Fuel as an Alternative Heat Energy
Many problems in the process of drying grain with a solar heat source. One of the factors is the erratic weather, where the rainy season comes along with harvest time. To overcome these obstacles, a grain dryer was designed that uses a rotary system that is simpler and more efficient and uses coconut shells as an alternative fuel. This study aims to obtain fast and affordable grain drying results by farmers using a rotary system dryer with coconut shell fuel. The benefit of this research is to provide an alternative solution for the community in dealing with harvesting in the rainy season by reducing land for drying grain. Equipment preparation was carried out in particular by using standard equipment to cut and connect the seat frame including the use of silencers and gasoline-fueled motors as propulsion and other supporting equipment. The components of each unit of grain drying machine are assembled and tested in stages according to procedures and functions. The test results show that the use of coconut shell can reach drying temperatures faster than the use of LPG, coconut shell fuel is better at reducing the moisture content of grain than the use of LPG. Testing of coconut shell fuel is done by drying 30 kg of grain for 20 minutes and 15 minutes. It can be concluded that the use of coconut shell as an alternative fuel can achieve a faster drying temperature than the use of LPG fuel. The use of coconut shell fuel to dry 30 kg of grain and reach a moisture content of up to 12% requires an effective time of 15 minutes

Determination of anthracnose (Colletotrichum gloeosporioides) resistance group in shallot (Allium cepa var. aggregatum)
Shallot anthracnose, caused by Colletotrichum gloeosporioides, is a devastating disease in a tropical country with high humidity and rainfall. Chemical control of anthracnose is neither economical nor eco-friendly, and genetic resistance is considered an efficient management method. This study aimed to determine the resistance groups of several shallot varieties and predict resistance heritability characteristics. In this study, a total of 13 Indonesian shallot varieties were evaluated for anthracnose resistance and separated into two groups, resistance and susceptible, based on K-means clustering developed by using disease resistance/susceptibility characteristics such as incubation period, disease incidence, disease severity, and spot diameter. The results indicate that the Agrihorti, Maja Cipanas, Batu Ijo, and Rubaru varieties were identified as resistant groups based on lower disease severity and incidence, smaller spot diameter, and longer incubation period. Maja Cipanas and Rubaru were more consistent in all variables, which is recommended as a source of genetic resistance genotypes. On the other hand, the Biru Lancor, Bima Brebes, Srikayang, Violetta, Slupu Merah, Pancasona, Sakato, Katumi, and Kuning varieties were identified as susceptible groups based on high disease severity and incidence, large spot diameter, and short incubation period.
Keywords: susceptibility characteristics, genetic resistance, k-means clustering, disease severit
Elevating Arabic Speaking Skills: Plotagon and Digital Comics as Catalysts for Enhanced Learning Engagement and Proficiency
Active student participation and engagement in diverse practice exercises are essential for mastering all four language skills. Due to the lack of active participation, students' proficiency in Arabic language learning, particularly in speaking skills (maharah kalam), falls below the required educational benchmarks. This research uses a quasi-experimental approach to assess the effectiveness of two different learning media: Plotagon for Tenth-grade students of IPS 1 and digital comics for Tenth-grade students of IPS 2 in improving Arabic speaking skills. The research findings indicate that students who used Plotagon as a learning tool to enhance their speaking skills achieved significantly better learning outcomes on average compared to students who used digital comics for the same purpose. Additionally, this study found that students who utilized Plotagon for learning exhibited higher engagement levels than those who used digital comics. These findings highlight the significance of active engagement in learning Arabic and indicate that Plotagon animation can be a valuable tool for enhancing learning outcomes and student engagement
KELAPA SAWIT SEBAGAI BASIS INDONESIA PENGHASIL UTAMA BIOFUEL DAN KARBON AKTIF
Indonesia merupakan salah satu negara produsen sawit dunia. Data menujukan bahwa tahun 2013 produksi minyak sawit Indonesia sebesar 30,5 juta ton dan naik 40,95 % dalam waktu 6 tahun. Tahun 2019 Produksi sawit Indonesia menjadi 43 juta ton. Perkembangan produksi minyak sawit Indonesia periode 2013-2019. Selain sebagai produsen sawit dunia, ternyata Indonesia juga sebagai pemimpin produsen sawit dunia. Produksi minyak sawit 43 juta ton tersebut akan menjadikan Indonesia berpotensi menghasilkan 12,9 juta ton tandan kosong kelapa sawit (TKKS) dalam setahun. Hal ini setara dengan 1.612.500 truk tandan kosong, suatu jumlah yang luar biasa besar. TKKS ini dapat dijadikan karbon aktif yang memenuhi standar karbon aktif bahkan bias menghasilkan karbon aktif berkualitas tinggi. Karbon aktif dapat digunakan untuk proses pemurnian pada industri, proses pengolahan air, proses pengelolaan limbah, proses bleaching, adsorpsi dan penghilang bau. Pada sisi lain dengan produksi minyak sawit sebanyak 43 juta metrik ton per tahun, dengan asumsi 15 persen saja diubah menjadi biodiesel dan biofuel, dengan yield rata-rata 70% maka dapat memenuhi biodiesel dan biofuel 4,515 juta ton pengelolaan atau setara 3.840 juta liter biodiesel dan biofuel
